Title: Tungsten thin-film resistor
Inventor: TAKASU HIROAKI
IPC: H01L27/04
Filed: 1989-01-27
Abstract: PURPOSE:To increase a resistivity and to reduce a temperature coefficient by a method wherein silicon is contained in a tungsten thin-film resistor. CONSTITUTION:Silicon is contained in a tungsten thin-film resistor so that a high resistance value at 1kOMEGA/square or higher of a sheet resistance value and a small temperature coefficient can be obtained. Since a resistance temperature coefficient of tungsten is positive and the resistance temperature coefficient of silicon is negative, a composite film resistor of these both can realize a small temperature coefficient (300ppm/ deg.C or lower). Thereby, a high resistance value can be obtained without a need to strictly control a film thickness; a circuit operation can be stabilized by reducing an influence by generated heat.

Title: Fuel jet nozzle for diesel pile hammer
Inventor: YONEKUBO YOSHIHARU
IPC: E02D7/12
Filed: 1981-02-12
Abstract: PURPOSE:To improve the firing of a pile driver for making the pile driving work efficient by providing in the nozzle holder a device by which the jet pressure of a fuel is adjusted by varying a pressure-regulating spring force to push a push bar for a needle valve which is slidable inside a nozzle holder. CONSTITUTION:When pulling downwards the operating rope 14 of a ratchet handle, the ratchet handle 10 makes a circular movement and a gear 8' also moves in the same direction. A pressure-regulating spring 3 is distorted and compressed when a ratchet gear connection screw 11, a gear 8, and a spring force regulating screw 6 displace in the same direction synchronously with the gear 8'. When loosening the rope 14, the handle 10 goes back to its original position but a ratchet claw 12 is still hooked on the gear 8, so that the gears 8 and 8' do not rotate. By pulling or loosening the operating rope 14, the regulating screw 6 is clamped, the push bar 2 for the needle valve is projected, and the jet pressure of fuel is gradually increased. Thus, switching from nozzle atomization to driving atomization or vice verse can be easily performed.

IPC: G09F9/33
Filed: 1994-02-16
Abstract: PURPOSE:To prevent the cost from greatly increasing and to eliminate color changes with a viewing and listening position by arranging three green projection tubes in array, arranging two red projection tubes on both the sides of the green projection tube arranged in the center, and arranging four blue projection tubes in the four corner. CONSTITUTION:The three green projection tubes 2 are arranged in the intermediate lateral array, one red projection tube 1 is arranged each in the stages above and below the center stage, and one projection tube 3 is arranged each in the four corners. The projection tubes 1-3 of the respective colors are symmetrical about the green projection tube 2 in any direction, so chromaticity variation is in a canceling direction and a hue difference with the viewing and listening position is not generated. Further, the screen luminance of green is dominant, so the three green projection tubes 2 are provided to increase a light output by 1.5 time as large as that of a six-tube system. Thus, the respective color projection tubes 1-3 are arranged symmetrically so as to make the chrominance variation with the viewing and listening position extremely small, so this receiver is adaptive to a large-sized screen, and high luminance and superior cost performance are obtained.
