Title: Anti-lock brake controller
Inventor: AOKI TAKASHI
IPC: B60T8/48
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To produce a suitable slow speed for increasing hydraulic pressure by disposing, between an open/close valve & an orifice and input hydraulic pressure passage, pressure-sensing-type flow regulating means which reduces the degree of throttling to restrict the flow of operating liquid more than an orifice according as the hydraulic pressure of a master cylinder side is larger than a predetermined value. SOLUTION: When hydraulic pressure for braking in an anti-lock control is increased, a control hydraulic pressure room 44 is cut off from a reservior and the differential pressure between a brake hydraulic room 43 and the control hydraulic room 44 is reduced according as operating liquid flows from the brake hydraulic room 43 to the control hydraulic room 44 in a locking state via the second orifice 42, thereby moving the piston 40 to a side increasing the volume of the brake hydraulic room 43 and thus increasing hydraulic pressure for braking. Pressure-sensing-type flow regulating means 4FL are disposed between an open/close valve 231 & the first orifice 241 and input hydraulic passageways 141 , 142 . When the output hydraulic pressure of the master cylinder M is larger than a setting pressure, the increase of hydraulic pressure for braking is slowly adjusted.

Filed: 1987-08-04
Abstract: PURPOSE:To reduce the rate of production of defective products by preventing any void from being formed in a semiconductor device by forming a solid resin material being a package material to resin-seal the semiconductor device into a conical trapezoidal shape. CONSTITUTION:A tablet 23 is formed of a solid resin material being a package material for resin-sealing a semiconductor device placed on a lead frame, and is formed into a conical trapezoidal shape as a whole. When a mold is drawn to a vacuum by a suction unit upon closing the mold, air involved in the tablet can also be exhausted from a space between the outer side surface of the tablet 23 and the wall surface of a pot to the outside of the mold. Thereupon, although the tablet 25 is expanded by expansion of air in the tablet, delta2 and delta3 are specified so as for the air to make contact with the wall surface of the pot, assuring that the air in the tablet is exhausted. Thus, any void involved in the tablet is prevented from being produced, thereby reducing the rate of production of defective products.

Abstract: PURPOSE:To form a plasma nitrided silicon film of a protective film which overcomes against moisture and ion contamination such as sodium with less crack and without damage on metal wirings by forming a metal inactive layer on the surface of metal wirings. CONSTITUTION:Aluminum is deposited on the entire semiconductor substrate 1, patterned, anodic oxidation is selectively performed with an acid which has solubility for an anodic oxidation film, a voltage is applied into weak acid such as citric acid to cover the surface of the aluminum with stable composite oxidized film. The surface of the aluminum wirings is formed with an inactive layer 9 of particularly stable aluminum, and aluminum inactive layer 10 is filled between the wirings. Thereafter, the surface is covered by a plasma nitrided silicon film. Since the surface of the aluminum becomes stable aluminum inactive state, activating molecules and activated atoms existing in gas plasma are prevented from being reacted with the surface of the aluminum. Since irregularity can be reduced, no entering route exists for molecules of water, and cracks are hardly produced in the plasma nitrided film.

Filed: 1988-08-06
Abstract: PURPOSE:To improve the purifying efficiency for a catalyst in a theoretical air-fuel ratio region by selecting the use of a PID control means or an integration control means according to the engine operation state. CONSTITUTION:A control circuit 24 judges a region in which the operation state of an engine 1 is in the high load and high speed revolution and the output is increased by making the air-fuel ratio rich or a region in which the cooling water temperature is low and the combustion state is instable immediately after the engine start. When the aimed air-fuel ratio is not set to a theoretical air-fuel ratio, the PID control for determining the feedback correction coefficient from the deviation between the aimed air-fuel ratio and the actual air-fuel ratio and the variation rate of the actual air-fuel rate is carried out. When the aimed air-fuel ratio is set to an ordinary theoretical air-fuel ratio, the integration control for carrying out the integration processing for the feedback correction coefficient is carried out according to the rich or lean state of the actual air-fuel ratio. Since the air-fuel ratio varies periodically within a minute range, having the theoretical air-fuel ratio as center, the purifying efficiency for a three-component catalytic converter 18 can be improved.
