Title: Battery charger
Inventor: YAMADA YUICHI
IPC: H02J7/10
Filed: 1993-11-30
Abstract: PURPOSE:To charge a battery intermittently by providing a charging control means which prepares and delivers a stop instruction and a restarting instruction to stop and restart charging operation. CONSTITUTION:This charger is provided with an current detection circuit 220, a timer 231 and a charging control part 232, which are added to a charging circuit. The charging control part 232 starts the timer 231 according to detection results by the current detection circuit 220, and according to an indication from the timer 231, the charging control part 232 controls the operation of a charging means 102 consisting of a constant voltage circuit 213 and a constant current circuit 214. In the current detection circuit 220, the voltage drop by a resistor 221 is amplified by an amplifier 222, and the current of the amplifier I increases to deliver comparative results between the output of the amplifier 222 and the reference voltage Vf1 from a voltage generating part 223 to the charging control part 232 as the detection results. It is thus possible to prevent the battery from being left over-charged and maintain the battery in a roughly full charged condition.

IPC: G11B19/20
Filed: 1988-11-29
Abstract: PURPOSE:To easily execute card cleaning at the time of card loading, to prevent a card from jumping-out and falling-off at the time of card eject and to easily take out the card with simple constitution by using a pair of rollers such as a cleaning roll and a driving roll. CONSTITUTION:A cleaning roller 1 has a roller shaft, which can be rotated in a necessary direction with being interlocked to motive force systems 6-12, and the cleaning roller 1 is freely fitted to a roller shaft 5 at a prescribed rotary angle relatively rotatably. A driving roller 14 has a friction coefficient, which is larger than that of the cleaning roller 1, with a card 17 and the driving roller is interlocked with the motive force systems 6-12 and rotated at the time of card loading. Then, at the time of card eject, the interlock with the motive force systems 6-12 is canceled and the driving roller faces to the cleaning roller 1 and sandwiches the card 17. Thus, with the simple constitution, the card cleaning is executed at the time of card loading and the card can be prevented from jumping-out and falling-off at the time of card eject. Then, the card can be easily taken out.

Title: Semiconductor memory
Inventor: KAGAMI AKIHIKO
IPC: G11C11/409
Filed: 1988-11-28
Abstract: PURPOSE:To contrive the high speed of reading and stabilize the reading by decreasing the precharge potential of a bit line connected to the memory cell of a dynamic memory before the rise of the potential of a word line. CONSTITUTION:A dummy word line DW is provided in the ordinary dynamic memory. During a resetting cycle, bit lines Di and the inverse of Di are precharge-balanced to an intermediate potential HVC by a signal PDL. During an active cycle, the word line DW falls from an H to an L, and reduces the potentials of the bit lines Di and the inverse of Di by two pieces of dummy capacity DCi and DCi+1 at the same capacity value. Next, when the potential of the word line WLi rises, a transistor (TR) Tii is turned on, the potential of the bit line Di finely changes around the potential, which has been reduced from the intermediate potential HVC, by information H or L accumulated in capacity Cii. Thus, the turning-on time of the TR Tii is made earlier compared with the ordinary case.

Title: Evaluation of heat resistance of cloth composite material
Inventor: IKEDA MORITAKA
IPC: D06M101/00
Filed: 1991-11-16
Abstract: PURPOSE:To simply and accurately evaluate solder heat resistance within a short time by simple equipment and a simple process by evaluating heat resistance using one composite sheet obtained by unifying only one cloth with an org. synthetic resin. CONSTITUTION:Only one cloth obtained from a glass fiber is impregnated with an org. synthetic resin such as an epoxy resin and the impregnated cloth is molded under heating to obtain one composite sheet. The heat resistance of a cloth composite material is evaluated using this composite sheet. Since this method is reduced in the effect due to a molding condition as compared with an evaluation method using a laminated sheet, the more accurate evaluation of heat resistance becomes possible. Further, this method is simple from the aspect of equipment and the evaluation of heat resistance can be performed by a conserved process and two or more kinds of samples can be also produced by this method. Therefore, solder heat resistance can be evaluated simply and accurately within a short time after effecting treatment against measling.

Thereby, the supervisor 3 accessed by the program 2 loads the library 8 corresponding to the address in the prescribed state to the main storage 4. Consequently, the system program can rapidly be accessed and the main storage can be effectively utilized.

Title: Optical code reader
Inventor: KIKUCHI YUJI
IPC: G06K7/00
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To provide an optical code reader which can read both bar codes and two-dimensional codes with high accuracy and also can be easily handled by using the visible length of the scanning light set on a plane as a photographing range index and at the same time moving a camera photographing reader before and after a two-dimensional code for its positioning control. SOLUTION: When a bar code 25 is read, the scanning light S, i.e., a visible beam radiated from a bar code reader 20 crosses the longitudinal direction of the code 25. Thus, the reader 20 reads the code 25. When a two-dimensional code 35 is read, the reader 20 operates by the switch signal received from a control part 40 to radiate the light S at a specific scanning angle after its switching even if a camera photographing reader 30 can read the two-dimensional code data. Then the code 35 is irradiated by the light S and at the same time the position control is performed so that the visible length of the light S set on a plane is slightly larger than the length of a single side that represents the size of the code 35.
