A function separation type photoconductor for use in electrophotography comprises an electroconductive substrate, a carrier generation layer vapor deposited on the substrate and a carrier transport layer formed on the carrier generation layer. The carrier generation layer is made of an indium phthalocyanine having the general formula ##STR1## wherein Me represents indium, and X is a halogen selected from the group consisting of chlorine, bromine and iodine.

A lead-acid battery according to the invention contains an electrode grid structure that comprises dispersoid-containing lead having relatively high strength and good corrosion resistance. The dispersoid particles exemplarily are selected from the oxides, nitrides and carbides that are substantially insoluble in lead and in sulfuric acid of concentration suitable for use in a lead-acid battery. Significantly, the dispersoid-containing lead has average grain size of at least 20 .mu.m. In conseque...

A public works device comprises a body, a telescopic jib including at least two sections of which a first section is pivotally mounted on the body and a second section is mounted for sliding relative to the first section, first control means for controlling relative sliding of the two sections and connected between the two sections, second control means for controlling pivoting of the first section relative to the body and which is connected between the first section and the body, and a linkage ...

The invention relates to a modular device that comprises a reaction zone that includes a catalyst bed and a zone for separation by distillation, as well as independent circulation channels for liquid fluid and gaseous fluid.

A method of thermally treating a substrate that has multiple layers is provided. A substrate layer that is covered on opposite sides is oxidized from side edges thereof toward a center thereof such that, via the following steps, a defined central portion is not oxidized. The substrate is heated in a process chamber to a prescribed treatment temperature. A hydrogen-rich water vapor is introduced into the process chamber for a specified period of time, wherein such introduction is effected prior t...

Disclosed is a laser/fiber mount that can advantageously be used in laser transmitter packages for a variety of purposes, including pump laser packages for optically amplified optical fiber transmission systems and fiber-to-the-home systems. Both laser and fiber are attached to the same unitary body, preferably a Si body. An integral heater serves to melt a quantity of solder that serves to bond the fiber to the body after alignment of the fiber to the laser. A relatively thick dielectric layer ...

We have discovered that coherent variation of at least two laser parameters can result in improved device performance, e.g., in pure amplitude or frequency modulation at frequencies substantially above 1 GHz, or in previously unattainable modulation frequencies. Among the relevant laser parameters are pumping rate, optical gain coefficient, photon lifetime, confinement factor, effective carrier temperature, output frequency and spontaneous emission factor. Exemplarily, the pumping rate and the o...

A curable composition which comprises: (1) a compound which contains on average more than 1 epoxy group per molecule; (2) a compound which contains on average more than 1 phenolic hydroxyl group per molecule; and (3) a catalytic amount of a catalyst compound which contains: (a) a cation containing at least one heterocyclic nitrogen-containing ring, and (b) an anion which is a conjugate base of fluoroarsenic acid, fluoroantimonic acid, fluorophosphoric acid, chloroarsenic acid, chloroantimonic ac...

The present invention relates to a driving unit comprising a multiple-stage planetary gear type reducer used to reduce rotation speed of a hydraulic motor and output the reduced rotation speed, which is used as a driving device for a traveling apparatus. The driving unit of the present invention is so structured that a trunnion boss for rotatably supporting a planetary gear train of a final state is supported at opposite ends thereof. This structure enables the load applied to the trunnion boss ...

An instrument is connected to a driving-in tool or drilling tool for elements on or in the form of an implant or drill for dentine. The tool includes an electric motor, the torque of which can be sensed, and which can be controlled by a control unit. A display unit is arranged so as to partly or fully display a curve representing the driving-in function performed. A tightening function is determined by a scale based on the slope of the curve, wherein a flatter slope represents a lower quality fu...
