Title: Detection of current or potential difference
Inventor: KAWAKATSU TAKESHI
IPC: G01R19/165
Filed: 1987-07-24
Abstract: PURPOSE:To easily detect a very slight potential difference or current and to detect integrated current by a simple and inexpensive device by using an electrochromic EC material as a detecting material. CONSTITUTION:Metallic magnesium bars 33, 35 are disposed near an underground embedded pipe 31 and are connected in a hand hole 37 disposed on the ground. About 800mV potential difference is generated between the pipe 31 and the bars 33, 35 and, therefore, the potential difference can be easily known at all times by using the EC material having the discoloration generation voltage (threshold voltage)( lower than said value, for example, WO3, as the detecting material. The detecting material for which the suitable EC material is used and a suitable detector are combined and are installed between the contacts B and C or B and D of the hand hole 37, by which the integrated current is exactly known and the degree of corrosion of the embedded pipe 31 and degree of elution of the magnesium bars 33, 35 are more exactly estimated by the simple means.

Title: Charge control circuit
Inventor: MAEKAWA TAKIO
IPC: H02J7/10
Filed: 1988-07-26
Abstract: PURPOSE:To perform highly accurate charge control by converting the maximum voltage of a battery under charge into digital value and storing the digital value, and suppressing the charge current when the terminal valtage of the battery drops by a predetermined level below the stored value. CONSTITUTION:A charge current output section 2 supplies charge current to a battery 8. The voltage of the battery 8 is detected through a battery voltage means 4 and converted into a digital value through an A/D converting section 31. The maximum digital value is stored in a memory section 33. When the digital value fed from the A/D converting section 31 drops by a predetermined amount below the maximum value stored in the memory section 33, a control section 32 suppresses the charge current fed from the charge current output section 2.

IPC: G06F3/06
Filed: 1989-07-19
Abstract: PURPOSE:To attain the transfer of data at a high speed between a computer and a magnetic disk device and to improve the data throughput by using an auxiliary storage means where the data to be transferred are written and a transfer data information storage means. CONSTITUTION:A main CPU 11 writes the transfer data block information (information on the address and the quantity of data to be transferred) into a RAM 15 and a hidden RAM 20 set in the same address as the RAM 15 before the transfer of data started to a magnetic disk device 10. At the same time, a cache CPU 18 transfers data to a cache RAM 19 from the device 10 via a high speed disk I/O 22 in response to the write of the transfer data block information to the RAM 20. Thus a DMA controller 14 can perform the high speed transfer of data between the RAM 15 and the RAM 19 via a host computer I/O 21. Then the data throughput is improved.

Title: Control circuit for loudspeaking call
Inventor: NONAMI TAKAYUKI
IPC: H04M1/60
Filed: 1985-08-26
Abstract: PURPOSE:To prevent the operation by a sound volume change-over switch due to the fluctuation of a noise level in a silent time by adding a low limiter circuit at each front stage of a transmission sound volume detector and a receiving sound volume detector. CONSTITUTION:An inputted voice and a noise are inputted to a transmission low limiter circuit 9 through a microphone amplifier 2. Only a signal having a level over a prescribed one can be passed through the circuit 9. The noise having the level under the prescribed one is not inputted to a transmission sound volume detector 10 by the circuit 9, making the output '0' same as the output in a silent time. That is the same as the operation at a receiving low limiter circuit 11. Therefore, a sound volume change-over switch controller 13 is not operated because the fluctuation of an input signal is not generated, then unnecessary switching operation is eliminated.

Title: Joining method of multiple parallel wires
Inventor: KOSAKA YASUO
IPC: H01B7/08
Filed: 1994-08-09
Abstract: PURPOSE:To continue and join insulating wires each other securely through a conductive member, by providing planes partitioned by mesh form grooves to at least one side pressure surface of a vibration horn and a receiver unit. CONSTITUTION:A vibration horn pressure surface 11 uses the junction of multiple parallel wires formed by joining 51 lines of polyurethane insulating wires with the diameter 0.11mm. On the pressure surface 11, numerous grooves 12 are provided orthogonally each other, and the planes partitioned by the grooves 12 are regular tetragons. When a copper foil is connected to the multiple parallel wires by an ultrasonic welding by using the vibration horn and the receiver unit, a secure all continuety can be obtained between all the 51 lines of insulating wires. In this case, by making the angle formed by the grooves 12 and the insulating wires 35 to 55 deg., the insulating wires are held by the planes 13 of the pressure surface 11, and the wires are never dropped in the grooves 12. Consequently, the insulating wires can be continued and joined each other securely through a conductive member, because there are planes 13 partitioned by the mesh form grooves 12.

Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To realize high integration of memory device by providing a pull-up device and a pull-down device being pulled up and down, respectively, based on a data inputted from an access device. SOLUTION: When a HIGH level voltage is inputted to a bit line BL after a word line WL is turned on in order to store a HIGH data at a node N, a pull-down transistor DT is turned off and a pull-up transistor UT is turned on. Consequently, HIGH data is stored at the node N. In this regard, a power supply voltage Vf is higher than a voltage being applied to the bit line BL by the threshold voltage of the pull-up transistor UP or more. When a LOW data is inputted to the bit line BL after the word line WL is turned off, the pull-up transistor UP is turned off and the pull-down transistor DT is turned on. Consequently, LOW data is stored at the node N.
