Title: Radio communication system
Inventor: YOSHIZAWA YASUNORI
IPC: H04B7/24
Filed: 1994-03-28
Abstract: PURPOSE:To provide a radio communication system which is highly stabilized and prevents the degradation of the communication quality in the middle of transmission of a slave station and shortens the time from acquisition of synchronism for reception to the start of transmission in the slave station. CONSTITUTION:Data is subjected to time division multiplexing based on the timing of a reference clock and is transmitted as a continuous wave in the case of transmission from a master station 10 to a slave station 30, and transmission information is transmitted in time division as a discontinuous burst signal in the case of transmission from the slave station 30 to the master station 10. A reproduced clock (a) is obtained by reproducing the reference clock of the master station 10, and output carrier reference signals (d) of local oscillators 324 controlled by control voltages generated based on the reproduced clock (a) are equal in all slave stations. While a transmitter 32 transmits the burst signal, a frequency control circuit 323 temporarily stops control of the local oscillator 324 by a control stop signal (b) from a logic circuit 33 to prevent the change of the transmission frequency in the middle of transmission.

Title: Circuit breaker
Inventor: YAMAZAKI HARUHIKO
IPC: H01H71/04
Filed: 1992-04-06
Abstract: PURPOSE:To detect whether there is trip in a breaker in its early stage after prior warning being output so as to optimize a device for protecting a load by detecting overcurrent in a main circuit after the prior warning being generated in its early stage, and outputting a warning signal followed by displaying warning. CONSTITUTION:When the current value in a main circuit is increased and the corresponding detected voltage exceeds a reference voltage in a PAL pick-up comparator 27a, the output from the comparator 27a operates a PAL time- limiting circuit 27b so as to generate a prior warning after a predetermined time. When the current value in the main circuit is further increased and the detected voltage exceeds the reference voltage in an LTD pick-up comparator 19a, the output 19a operates an overcurrent pick-up warning output circuit 29 so as to generate a warning signal. This signal closes a warning output displaying circuit so as to light a lamp, and an LTD time-limiting circuit 19b also operates so as to generate a trip signal after a predetermined time. Accordingly, whether there is trip in the breaker after prior warning being output can be detected in its early stage, so that an adequate load protection measure can be taken.

Title: Electronic flash device
Inventor: SAKAMOTO HIROSHI
IPC: G03B7/16
Filed: 1988-04-05
Abstract: PURPOSE:To confirm dimming only by pushing a test flash button by setting a diaphragm value set on a camera side as a one for outside automatic dimming in TTL automatic dimming operation when the operation is switched from said TTL automatic dimming to external automatic dimming. CONSTITUTION:When a dimming mode changeover switch 12 is set in the outside automatic dimming (mode A) to select the mode A, the transmission of IOS sensitivity to a flash device side from the camera side continues to stop transmitting the diaphragm value. At that time, the CPU 17 of the flash device stores the diaphragm value in a TTL mode just before it is switched, and adopts said value as a diaphragm value in the mode A. With the diaphragm value determined, an output corresponding to the relation with the ISO sensitivity determines the reference voltage of an outside dimming control circuit 13 through a decoder 14 to switch the gain of a metering amplifier. Then, the test flash switch 6 is pushed to flash one time in the mode A, and the alarm is displayed when appropriate exposure cannot be obtained. Only by pushing the test flash button, test flash can thereby be carried out.
