Title: Anti-lock braking device
Inventor: SEKIGUCHI AKIHIKO
IPC: B60T8/48
Filed: 1994-11-04
Abstract: PURPOSE: To utilize rear wheel braking force more efficiently than an actual braking force distribution even when diagonal wheels are select-low controlled at the same time. CONSTITUTION: In anti-lock control pressure reduction, braking fluid inside a right front wheel FR wheel cylinder 2 is let flow into a reservoir via a flow passage 12 in a piston 11, while braking fluid inside a left rear wheel cylinder 3 is let flow into the reservoir via an orifice 15, so that a pressure reduction rate of the rear wheel cylinder 3 becomes lower than that of the front wheel cylinder 2. As the piston 11 is moved by means of a fluid pressure of a master cylinder while a pressurizing condition is accomplished again, the fluid pressure from the master cylinder is fed to the rear wheel cylinder 3 via a proportioning valve 5 and is fed to the front wheel cylinder 2 only via an orifice 13 formed in the piston 11. Therefore, a pressurizing rate to the front wheel cylinder 2 becomes lower than that to the rear wheel cylinder 3.

IPC: H01L23/522
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To increase the densities of borophosphate-silicate glass and an oxide existing on the glass before forming a pattern, by exposing the glass and undoped oxide to a high temperature before a line patterning step, a contact etching step, and an ion implanting step. SOLUTION: After a dielectric layer of borophosphate-silicate glass having fluidity is stuck to the surface of a substrate, another dielectric layer of a material having no fluidity is stuck to the surface of the glass layer. Then, contact etching and a high dose of ion implantation are performed so that an undoped oxide composed of SiO2 existing on the dielectric layer having no fluidity can be exposed to a junction activating annealing temperature, namely, a high annealing temperature of about 800 deg.C to 1,100 deg.C. After the ion implantation, contacts and lines are metallized by again exposing the contacts and lines to a high annealing temperature. Therefore, the densities of the borophosphate-silicate glass and SiO2 existing on the glass can be increased before forming a pattern.

Title: Driver in ink jet printer
Inventor: FUTAGAWA YOSHIKIYO
IPC: B41J2/055
Filed: 1989-10-20
Abstract: PURPOSE:To reduce the number of components and to stabilize an ink jetting by a method wherein a scanning voltage generation means made of an amplifier for a pair of transistors serially connected to a power source generates a scanning voltage of an arbitrary waveform and a low impedance. CONSTITUTION:A signal on a line 11a excites a transistor TR2 of N channel, converts the level through resistances R4 and R5, and rapidly raises transistors TR3 and TR4 of a P channel. A transistor TR7, which is electrically conducted at a timing of a signal on a line 11c to have a grounding potential at the last stage of a scanning voltage in a falling direction, compensates the threshold of the gate electrode of a transistor TR6. Diodes D1 and D2 prevent the transistors TR3 and TR4 from having an inverted bias. In this construction of a scanning voltage generation means 10, a scanning voltage has approximately the same amplitude as that of a power source voltage, and an output impedance is determined by the transistor TR4 in the rising direction and by the transistors TR6 and TR7 in the falling direction to be set at approximately 1OMEGA. A low imped ance output realizes a stable ink jetting state with no possibility that a change in load may affect a scanning voltage waveform.
