Patent JP-S6383991-A (JP)
Title: Static memory
Inventor: MATSUI MASAKI
IPC: G11C11/419
Filed: 1986-09-29
Abstract: PURPOSE:To perform read operation at a high speed and reduce power consumption by providing a pair of transistors TRs for n-channel type transmission gate selectively controlled by a column selection signal and a pair of TRs for p-channel type bit line pull-up controlled to the non-selected state. CONSTITUTION:On a selected column, a pair of TRs Q14 and Q15 for pull-up are not selected but a pair of TRs Q3 and Q4 for transmission gate are selected. At the time of read-out, a pair of TRs Q3 and Q4 for transmission gate are loads for pull-up of a pair of bit lines BL, but they are not turned on until bit line potentials are reduced from the supply power potential by threshold voltages of TRs Q3 and Q4 for transmission gate. Consequently, no DC current paths exist on bit lines in the range from the supply power potential to potentials lower than it by threshold voltages, and the potential difference between a pair of bit lines is increased at a high speed because the speed of this increase is determined by only the leading-in current of a memory cell, and the quick sense operation is performed.

Title: Controller for separately excited ac/dc converter
Inventor: IIO HISATAKA
IPC: H02J1/00
Filed: 1993-08-25
Abstract: PURPOSE:To allow continuous stable operation of an AC/DC converter while feeding power as high as possible even in case of three-phase imbalance by effecting constant pulse interval control when the voltage of an AC bus is balanced whereas detecting the phase of voltage being applied to each arm individually when the voltage of AC bus is imbalanced. CONSTITUTION:When a relay 10 is disabled, i.e., the voltage of an AC system is balanced, by an operating signal fed from an undervoltage relay for monitoring the voltage of an AC system connected with converters 3, 7, the converters 3, 7 are operated under constant pulse interval control thus suppressing the nontheoretical harmonics generated therefrom. Upon function of the relay 10, e.g. when the voltage imbalance increases or the voltage drops due to fault on the AC system, the voltage phase is detected for each phase arm of the converters 3, 7 thus operating the converters 3, 7 while ensuring the margin angle required by each arm for normal commutation.

Title: Printer control device
Inventor: HONDA SUSUMU
IPC: B41J5/30
Filed: 1990-09-04
Abstract: PURPOSE:To prevent page data from becoming lost by ensuring that page data can be transferred to a parking storage from a receiving buffer part even if a power supply switch is turned OFF and at the same time, a power supply voltage can be applied to the parking storage independently. CONSTITUTION:If a power supply switch 6c is changed from 'ON' position to 'OFF' position by an operator, a power supply monitor 6b detects the OFF state and transmits a detection signal Q to a power supply voltage control part 6a. Then the power supply control part 6a which has received the detection signal Q checks count information in a buffer counter 5. As the count information in the buffer counter 5 indicates the amount of page data in the receiving buffer 2, a power supply voltage is applied to each part by the power supply control part 6a, if the count information is present in the buffer counter 5. In this case, data page is transferred to the parking storage 4 from the receiving buffer 2 by a data transfer control part 3, and the power supply voltage continues to be applied by the power supply control part 6a until the count information is no longer present.

IPC: E21C35/18
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a crack by providing a first tip protruded from the tip face of a cylindrical shank, and second tips divided along the circumferential direction of the shank so as to cover the tip part peripheral surface of the shank. SOLUTION: A recessed part 1a is formed at the tip face of a cylindrical shank 1 coaxially with the shank 1 toward the base end side. A first tip 3 is planted in the recessed part 1a fixedly by brazing in the state of protruding from the tip face of the shank 1. Semicylindrical second tips 4c divided in plural pieces along the circumferential direction of the shank 1 are further planted radially outward of the recessed part 1a fixedly by brazing so as to cover the peripheral surface of the shank 1, thus forming a round pick. Accordingly, even though distortion is generated between the second tip 4c and the shank 1 at the time of fixing the second tip 4c to the shank 1 by brazing, this distortion is absorbed by the joint of the second tip 4c so as to prevent the generation of a crack in the second tip 4c and the fall of the second tip 4c.

IPC: B62D137/00
Filed: 1991-09-12
Abstract: PURPOSE:To reduce fatigue of a driver at steady turning by providing a second setting means in which an assisting force larger than the assisting force of a first setting means according to steady turning state is set. CONSTITUTION:A control unit 60 has a function to judge if it is in the steady turning state, that is, a steering wheel 13 held or not from outputs of a steering angle sensor 62 and a steering angular velocity sensor 63. When brought into the steady turning state, a control means which has been operated so far by an assisting force set by a first setting means is operated according to the assisting force set by a second setting means. Here, as the assisting force set by the second setting means is set at a value larger than the assisting force set by the first setting means and suitable for steady turning, a holding force of the steering wheel is reduced at steady turning. Thus, burden of a driver becomes smaller and fatigue of the driver can be reduced.

Abstract: PURPOSE:To enhance the sensitivity of a CCD camera without causing the deterioration of a resolution or the generation of a flicker by adding the charge of more than two picture elements arranged in a horizontal direction, and operating an inter-field offset sampling. CONSTITUTION:A reset pulse RS is prepared by thinning out the conventional reset pulse by every other piece. The charge for the two successive picture elements in the horizontal direction is successively stored in a floating capacitor FC by driving a CCD 2 for a horizontal transfer by such driving signal, the charge for the two picture elements is added so that the output of the CCD 2 can be two times as much as the conventional output, and the sensitivity can be two times as the result. Moreover, the phase of the reset pulse is shifted by 180 degrees between the first field and the second field in order to operate the inter-field offset sampling. That is, the position of the picture elements to be added is changed at every field so that a spatial sampling point can be used as the inter-field offset sampling.
