Title: Semiconductor storage device
Inventor: HIDAKA HIDETO
IPC: G11C11/401
Filed: 1986-06-20
Abstract: PURPOSE:To eliminate undesired power consumption by inhibiting the operation of a column decoder system in response to a prescribed control signal inputted externally when a column address strobe signal is in nonactive state. CONSTITUTION:A signal S is given to one input of a NAND gate 32 via an inverter 31 and signals WE, CAS are given to one and the other input of an OR gate 35 via inverters 33, 34 respectively. The output of the OR gate 35 is given to the other input of the NAND gate 32 and a signal CE is outputted from the output of the NAND gate. When the signal CAS is on a H level, that is, in the nonactive state, when the signal WE is kept on a L level, the signal CE is kept on the H level. Thus, no column decoder system is operated at the CAS standby state and the internal circuit is inoperative regardless of the transition of an undesired external address signal. Thus, undesired consumption of power current Icc is eliminated.

IPC: G05B23/02
Filed: 1992-05-12
Abstract: PURPOSE:To correctly evaluate the equivalence regardless of error accumulation in the case of the existence of an integral element or a learning element in the control logic of a controller. CONSTITUTION:Control result data is inputted from an engine to a controller 40 whose equivalence to an engine control system 30 should be verified, and control signals from both of them are compared with each other by a comparator 14.

IPC: G11B7/246
Filed: 1988-06-14
Abstract: PURPOSE:To obtain an optical data recording medium excellent in stability and low in manufacturing cost by supporting a layer containing a specific dye in contact with an injection molded polycarbonate substrate. CONSTITUTION:A layer based on a dye represented by formula (I) (wherein X is ClO4, PF6 or CF3SO3) is supported in contact with a substrate and a layer such as a bottom coat layer is not provided between the dye layer and the substrate. From such an aspect that there is no possibility of explosion, dyes wherein X is PF6 and CF3SO3 are pref. among the dyes represented by the formula (I) and, when a viewpoint of raw material cost and light fastness is further added, a dye wherein X is PF6 is most pref. When the support amount of the dye represented by the formula (I) is low, satisfactory optical characteristics are not obtained and, therefore, the dye is supported in such an amount that the absorbancy measured through the substrate to light of 830nm pref. becomes 0.3-1.5. An injection molded polycarbonate substrate may be one of a continuous servo system equipped with grooves or sampled servo system equipped with discrete marks but the substrate of the sampled servo system easy to receive the effect of a dimensional change shows more marked effect.

Title: Braking force control method of sliding prevention device
Inventor: KUMAGAI NORIMICHI
IPC: B60T8/66
Filed: 1992-05-14
Abstract: PURPOSE:To suppress reduction of braking force and increase of brake distance by reducing braking force for a certain period of time when it is detected that wheels slide, monitoring rotation speed of wheels for a certain period of time after that, and reducing braking force for a certain period of time again if rotation speed of wheels is not restored to the vicinity of vehicle speed. CONSTITUTION:When sliding is detected (point A'), brake cylinder pressure is reduced for a certain period of time (t1), and then brake cylinder pressure is maintained for a certain period of time (t2). The certain periods of time t1, t2, are the time which are determined in advance by taking the operation of a sliding prevention device into considerations. Brake cylinder pressure immediately when the point (B') where rotation of wheels is directed toward readhesion is detected during a series of operations is held, and brake cylinder pressure is reduced again when the point B' does not exist. This operation is continued until the point B' is detected. When the point B' is detected, brake cylinder pressure at the time is held, and when the readhesion point (C') is detected, brake cylinder pressure is restored to the predetermined value.
