Title: Control device for elevator
Inventor: SASAO ISAO
IPC: H02P27/06
Filed: 1987-01-16
Abstract: PURPOSE:To allow good elevator control at all times, by detecting the offset of a current detector to detect the output current of an inverter while the elevator is stopping and by automatically correcting the offset. CONSTITUTION:A regulator 21 controls an inverter based on a command speed signal PA, a signal PB to indicate the rotating speed of a lifting motor and the detected current IA of a current detector to detect the three-phase output current of the inverter with which ths three-phase AC output is applied to the lifting motor. It also controls the rotating speed of the lifting motor. Here, the command current IB=0 while an elevator is stopping, but no detected current IA=0 because of the offset of current detector. On this account, even in the stoppage of the elevator, the command other than '0' is outputted to the inverter, when the second current command circuit 22 can make the command to the inverter approximately '0' by outputting the correction value IOFS so that the output value IZ of an amplifier 17 will be lower than the specified value.

Title: High pressure metal-vapor electric-discharge lamp
Inventor: SAITOU MASATO
IPC: H01J61/56
Filed: 1982-01-21
Abstract: PURPOSE:To give a pulse voltage which can securely perform starting of a lamp by connecting a non-linear capacitor parallel to an emission tube, and installing said capacitor either in an outer tube or in a base. CONSTITUTION:An emission tube 1 is installed in an outer tube 17. A non-linear capacitor 21 having a capacity of over 1,000PF and a saturation voltage of over 20V is connected parallel to the emission tube 1, and installed either in the outer tube 17 or in a base 18. As indicated in the figure, while a current flows in the capacitor 21 which is made of barium titanate or the like, the charge (Q) of the capacitor 21 increases as its voltage (V) increases. However, when the voltage (V) reaches a given value (Vs), the charge (Q) is saturated, and the current doesn't flow in the capacitor 21. Therefore, when the capacitor 21 is applied to a circuit indicated in the figure, a pulse voltage sufficiently high for the starting of a lamp is applied to the lamp since any current doesn't flow in the capacitor 21 when the voltage (V) of the capacitor 21 reaches the value (Vs).

Title: Method and apparatus for measuring peak voltage
Inventor: OOTA SEISHIROU
IPC: G01R19/04
Filed: 1983-01-18
Abstract: PURPOSE:To enable the measurement of a peak voltage value with a higher reliability of a tester and a simplified maintenance by adding a simple comparator circuit to a DC voltmeter and a DC voltage signal generator to be used. CONSTITUTION:When a measuring signal voltage > a DC voltage signal generator 1 in the output voltage, a voltage command of (E+DELTAE) obtained by adding a fixed voltage DELTAE allowed for accuracy necessary for measurement to a voltage value command signal E with an adder or the like is applied to the DC voltage signal generator 1 and a measuring status logic signal is observed again. The voltage value command signal rises gradually by an increment DELTAE. When a measuring signal <= the DC voltage signal generator, the rise of the voltage value command signal is stopped to continue the observation of a measuring status logic signal. This method can achieve a higher reliability, a simplified maintenance and a lighter weight.

CONSTITUTION: A 24-phase multiplex node network consists of 16 pieces of processing nodes PN0-PN15 and eight pieces of switch cards (remote nodes) SN0-SN7, and the PNO is defined as a CSN. As for a segment string, the received signal of the remote node is transmitted through the transmission segment to the other transmission segment of that node corresponding to the alternate sequence of the transmission segment and a path through segment. A node time value shown by a synchronizing message is the reference time of the CSN corresponding to that transmission time and increases just for the sum of path through delay along the VTD and that string and known execution delay at the final node. The known execution delay corresponds to difference between the initial set time of time counter of the remote node and synchronizing message catching time.

Filed: 1999-01-18
Abstract: PROBLEM TO BE SOLVED: To obtain a reproducing device which can release a lock state, even when a password is forgotten by inputting release time information releasing a lock state by an operator, deciding whether or not a lock state is to be held based on inputted release information, and releasing a lock state based on the decision. SOLUTION: A CPU 23 decides whether or not a password is inputted, and next it decides whether the inputted pass word is stored or not. A CPU 23 stores a level value selected by performing level setting processing in a RAM 27. When a time-setting switch is turned on, the CPU 23 decides that time setting indication is performed, and time setting processing is started. An operator inputs a lock start time and a lock finish time on a time setting screen, and a finish switch is selected. If a lock finish time is not inputted, time setting processing is not completed, and since lock is released at the set lock finish time without inputting a pass word, lock can be released even when password is forgotten.
