Patent JP-H114548-A (JP)
Title: Secondary battery pack
Inventor: NAGAI TAMIJI
IPC: H02J7/10
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To simplify the circuit connected with a secondary battery by performing control of a charging circuit and a protection circuit through a common circuit. SOLUTION: When DC power for charging is supplied externally to terminals 1, 2, a voltage detection circuit 12 performs power supply detection processing. Constant voltage control is then performed at a constant voltage circuit 11 through detection processing for dropping a voltage detected by voltage division through resistors R1, R2 by a specified level below a reference voltage thus performing constant voltage charging of a secondary battery B. When the constant voltage circuit 11 operates erroneously and a voltage higher than the reference voltage is applied, a stop circuit 14 functions to bring a switch circuit 13 into unconnected state thus stopping the charging operation and protecting the charging circuit.  More specifically, constant voltage charging can be carried out based on detection through a single voltage detection circuit 12 and protective operation is carried out when an abnormal voltage is applied. Consequently, charging and protection can be carried out through simple circuitry comprising a single voltage detection circuit.

Title: Optical loop buffer increasing light absorption ratio of buffered signal
Inventor: NORTE DAVID A
IPC: H04B10/293
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To provide the optical loop buffer which prolongs the storage time of a signal by increasing the light absorption ratio of the buffered signal. SOLUTION: A received signal λ1 is amplified by an amplifier 110 and coupled (put together) with a 2nd signal of different wavelength λ2 from a generator 116. This composite signal is amplified by SOA 118 and then the 2nd signal is modulated. A filter 128 extracts the reception signal from the output of the SOA and the signal is attenuated because of the loss of the filter and the loss of a delay unit 126. The 2nd signal which is modulated as mentioned above is extracted by a filter 124 from the SOA output, amplified by an amplifier 122, and coupled (put together) with the extracted reception signal. This composite signal is amplified by the other SOA 132, and consequently the reception signal is modulated, thereby increasing the light absorption ratio of the reception signal.

Title: Dynamic balancing machine
Inventor: MATSUMOTO EIJI
IPC: G01M1/04
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To prevent overturning of a workpiece in fitting the workpiece in a dynamic balancing machine for measuring the imbalance quantity of the workpiece such as a fan. SOLUTION: Vibrating frames 1A, 1B are provided with self-aligning bearing 6A, 6B, and an arbor 9 is fitted to the bearings 6A, 6B. The arbor 9 is driven by a motor 2, and a workpiece W is fitted through an adaptor 13.
