A resistor having a ceramic sintered body and at least one resistor film embedded therein so as to be covered by the ceramic sintered body except for portions of the resistor film-chat are connected to external electrodes. The sintered body is mainly composed of ZnO, and contains at least one element of Bi, Pb, B and Si as a subcomponent with respect to the main component.

A fixed wrench has a handle, and an open end located at one end of the handle and formed of a left jaw and a right jaw. The left jaw and the right jaw are provided respectively with a first actuating surface and a second actuating surface. A first holding portion for holding a first fastening piece is formed by the first actuating surfaces of the left jaw and the right jaw. A second holding portion is formed by the second actuating surfaces of the left jaw and the right jaw for holding a second ...

A cursor which is fixed at a point in a display screen, where navigational controls move the contents of display screen rather than the cursor. Preferably the cursor is used in conjunction with hand held displays.

An easy to install and easy to expand broadband local area network is disclosed. The network has a star-type architecture based upon a fixed-gain, fixed-loss approach to amplification and a star-feeder approach to providing user connection to the network.

A turret is movable in azimuth within a turret support structure and a large caliber cannon is movable in elevation within the turret. An automatic loading mechanism is contained within the turret operating to move fixed ammunition rounds between a turret mounted magazine and the cannon breech. The magazine in one embodiment includes a rotating carousel and a number of rotatable drums mounted thereon. The drums have storage cells for ammunition rounds. A transfer mechanism operates to move the r...

A fixed quality source coder receives and performs VQ on an input signal I.sub.D. The signal I.sub.D may be characterized by the number of samples/frame and bits per sample, and may be provided by a traditional source coder. The traditional source coder may include a sample-and-hold (S/H) circuit producing rxs samples/frame and an ADC providing n bits per pixel. In a first embodiment, the number of bits/sample is increased. In the second embodiment, the number of samples/frame is increased. In a...

A divider used in containers has intersecting partitions and two parallel tying strips located centrally of the divider. The tying strips hold the partitions substantially parallel so that the divider may be inserted by machine into a container and will remain in a fixed spacial relationship while the container is filled with goods by automatic casing machinery. The partitions and the tying strips have transverse cuts and are joined by interlocking the cuts in a rectilinear network. The corners ...

A fail-fixed servovalve includes a jet pipe for discharging a pressurized liquid wherein the jet pipe may be selectively signaled to deflect and unbalance the pressures at opposing ends of a spool which would otherwise remain centered within a sleeve by resilient means at opposing ends thereof. The spool includes a plurality of circumferentially relieved areas interspaced between a plurality of lands with interconnecting passages therebetween wherein a servopiston may be actuated to move by pres...
