Abstract: PURPOSE:To retrieve the information at a high speed when the number of virtual units is set to an optical card by recording and reproducing the data retrieving directory to the optical card with a command given from a host computer. CONSTITUTION:The data retrieving directory 10 is recorded and reproduced to an optical card 1 with a command given from a host computer of an information recording/reproducing system. Then directory 10 consists of a logical unit number LUN11, a key word 12, a relative address 13 and a pointer 14. While the card 1 is divided into two areas. The pointer 14 consists of an updating flag 141, a track number (relative address) 142 to which a key word to be updated is written, and a number LUN143. Then it is possible to avoid a mistake where the position of a keyboard is written twice at its update by writing the track number 142 where the key word to be updated is written. Then an identification flag updated by the pointer 14 is written.

Title: Motor self-cooling type air pump
Inventor: IO SHINICHI
IPC: F04B39/06
Filed: 1984-06-15
Abstract: PURPOSE:To prevent a motor from overheating when it is operated for a long time by allowing air which flows through suction and exhaust valves provided on a piston and a diaphragm while an air pump is operated, to be sucked and exhausted through suction and exhaust ports which are provided close to said motor. CONSTITUTION:When a DC power source is applied to a brush 15, a rotation torque is generated in a rotor 13 through a commutator 14, to rotate a crank shaft 17, causing a rod 19 to start reciprocating motion. Thereupon, due to the action of flowing ports 23 and valve bodies 25 which are provided on a diaphragm 21 and a piston 20, and to a flowing port 27 and a valve body 28 provided on a partition 11a, air flows from an actuator chamber 26 into a pump chamber 30 and a crankcase 24, to suck and operate an actuator. The air flowed into the crankcase 24, flows outward through a suction and exhaust port 29, after passing by the side of the rotor 13 as shown by the arrow C. Accordingly, the rotor 13 which is a main component of a motor, can be cooled by this air, attaining the desired end.

Title: High impedance input circuit
Inventor: WAKUTA TETSUYA
IPC: H03K19/0175
Filed: 1994-06-06
Abstract: PURPOSE:To enlarge an input dynamic range and to facilitate connection with other circuit blocks by setting the center DC potential of a high impedance input circuit near the half of a power supply potential. CONSTITUTION:When a current made flow to the base of a first transistor 1 changes for DELTAi, current change at the emitter of the first transistor 1 and the base of a second transistor 2 becomes hFE.DELTAi. Thus, the current of hFE<2>.DELTAi changes in the emitter and collector of the transistor 2 and the change of hFE<2>.DELTAi+hFE.DELTAi of the current for the added portion of the emitter current of the transistor 1 and the collector current of the transistor 2 appears in output. That is, the input impedance of the base of the transistor 1 becomes approximately (hFE<2>)-fold of the impedance in the emitter, the voltage value upper limit of a signal input terminal 8 becomes the collector potential VCC-Vbe of the transistor 1, a lower limit becomes the two of the Vbe of a current source 7 and the Vbe of the transistor 1 and the followup ability of the output to input is improved.

Title: Specific gravity detecting method of electrolyte in lead storage battery
Inventor: YONEZU KUNIO
IPC: H01M50/569
Filed: 1983-07-06
Abstract: PURPOSE:To measure the stable potential where the fluctuation between the electrodes is reduced with high accuracy, by discharging an electrode composed of PbO2 or Pb chraged continuously with low current for short time then opening the circuit and measuring the voltage. CONSTITUTION:PbO2 or Pb electrode charged continuously with low current density, for example 5mA/cm<2>, is discharged for short time then open circuited to measure the voltage. Since it is charged continuously with low current, it causes no deterioration due to reaction with diluted sulfuric acid while since the potential is measured under open circuit, polarization due to charge/discharge will never occur to reduce fluctuation between electrodes resulting in accurate measurement of stable potential.

Title: Character input device
Inventor: AOKI YUTAKA
IPC: G06K9/03
Filed: 1986-05-29
Abstract: PURPOSE:To obtain an easily useable character input device which requires no special preparation, by outputting continuously a retreat code and a selected character code, when a user selects a correct candidate after having outputted only a character code of the first candidate. CONSTITUTION:When a user writes a character, a two-dimensional coordinate data is inputted in detail by a coordinate input means 10 in accordance with a motion of his hand, and a decision of its write end is executed. In other case than the write end, its coordinate data is sent to a character recognizing means 11, and the input of the coordinate data is repeated. In case of the write end, the means 11 executes the recognition, based on the inputted coordinate data. A result of recognition becomes a candidate character code group, but only a first candidate in said group is sent to a code output means 13 and its code is outputted. The user decides whether a candidate has been selected or not by using a character selecting means 12, and thereafter, if it is not selected, the device is prepared for the next character input. Also, when said selection has been executed, first of all, a retreat code is outputted through the means 13, and subsequently, a character code of the selected candidate is outputted in the same way, and thereafter, the device is prepared for the next character input.

Title: Semiconductor switch circuit
Inventor: KANBARA YOSHITAKA
IPC: H02M1/08
Filed: 1979-09-28
Abstract: PURPOSE:To increase both the dV/dt limit value and the gate sensitivity as well as to decrease the malfunction by securing the quick transfer for the variable resistance element provided to the photo thyristor to the high resistance state via the light variable resistance element which is controlled by the light ignition signal. CONSTITUTION:With application of the sudden voltage to anode terminal A of photo thyristor 11, the capacitor comprising the nB-pC region flows the charge current to transfer transistor 2 from the high resistance state to the low resistance state. And thus the short-circuit is secured between the gate and cathode terminals of thyristor 11 to prevent the erroneous ignition. In case the ignition signal is applied in the state under which transistor 2 is not reset to the high resistance state yet, transistor 5 is transferred to the low resistance state via part of the gate ignition signal sent from light emitting diode 8. Thus the residual carrier at the base region of transistor 2 is discharged to cathode terminal K of thyristor 11 to secure the quick reset to the high resistance state.

Title: Primary battery, secondary battery, charging method and device for secondary battery
Inventor: HANEDA SHOJI
IPC: H01M10/30
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent producing of dendrite in a secondary battery at charging, preclude deterioration, etc., of the cyclic characteristics of the secondary battery, and hinder the battery capacity from decreasing. SOLUTION: A secondary battery 15 is accommodated in an accommodation part 5 located in a DC magnetic field generated by permanent magnets 11 and 13 of a DC magnetic field generation part. An AC magnetic field generated perpendicular to the DC magnetic filed is impressed on the secondary battery 15 from electromagnets 7 and 9 of an AC magnetic field generation part. With this impression of DC magnetic field and AC magnetic field on the secondary battery 15, vibration is generated in a magnetic filed 23 in a separator 21, and in this condition, charging on the battery 15 is conducted. The vibration of the magnetic powder 23 suppresses deposition of the metal as the negative electrode material likely to be produced in the battery 15 at the time of charging. Accordingly there is no problem even if metal is used as negative electrode material.  Because no dendorite is produced at charging even if the thickness of the separator is lessened, this is free of inconvenience such that the battery capacity decreases.
