Title: Flash light emitting device
Inventor: YAMADA HIROSHI
IPC: G03B15/05
Filed: 1990-06-05
Abstract: PURPOSE:To eliminate the need of using a capacitor with large capacitance as a capacitor for the gate bias of a gate insulating type bipolar transistor (IGBT) by starting a power source circuit just before light emission and turning on the IGBT. CONSTITUTION:A charging start control signal is outputted to a power source circuit 2 from a CPU 10 through a charging control circuit 9, and the circuit 2 applies charges for emitting light to a main capacitor 3 through a diode 4. When the main capacitor 3 attains a specified voltage, the CPU 10 outputs a charging stop control signal so a s to stop the action of the circuit 2. When the CPU 10 receives a light emission signal, it actuates the circuit 2 to store the charges in a capacity element in a gate bias circuit 6 and stops the actuation of the circuit 2 after turning on the IGBT 8, then it actuates a trigger circuit 5 to excite a discharge tube 1 to emit the light. Thus, it is necessary to use the capacitor with large capacitance for the gate bias of the IGBT.

Title: Capacitor-excitation type brushless self-exciting synchronous generator
Inventor: MASUDA YUTAKA
IPC: H02K19/28
Filed: 1979-11-15
Abstract: PURPOSE:To eliminate the abnormal increase in the output voltage of the capacitor- excitation brushless self-exciting synchronous generator even if a rotor is excessively rotated by controlling a stator current in response to the rotating speed of the rotor. CONSTITUTION:When the rotor is rotated with an engine, small amount of lead current Ic will flow in a capacitor-excitation winding 2 due to the residual magnetic flux of the rotor. Thereafter, the lead current Ic of a winding 2 will gradually increase due to the self-excitation effect, and a voltage is established. At this time, an output voltage Ea is inducted at a load winding 1. If the engine rotating speed is excessively increased, the frequency of the ignition pulse is increased so that the output voltage of a frequency-voltage converter 16 is accordingly raised. Thus, a comparator 17 will produce a positive voltage, thereby conducting a transistor 18.  Thus, a coil 12 of a relay 10 is excited. Thus, a normally closed contact 11 is  opened, thereby breaking the lead current in the winding 2. Accordingly, the output voltage Ea is thus lowered.

Title: Television signal transmitting system

IPC: H04N7/025
Filed: 1979-11-15
Abstract: PURPOSE:To enable to transmit the picture and audio in high quality in the same band as television signal transmission system, by playing back the signal of one field of picture signal continously for the 2 fields. CONSTITUTION:Only one field A1 among one frame of input continuous picture signal, is transmitted, and transmission is made by inserting the audio a' in which the audio (a) for one frame's share is compressed for the time axis in the period of the field A2 not transmitted. In this case, at the V blanking period of the field to be transmitted, the identifying code of picture signal is added. When the picture signal identifying code is discriminated from the transmitted input signal, one field's share is taken into the picture memory, it is operated as the field memory for the next field period to play back the same signal A1. Further, the audio signal a' transmitted at the next field, is extended at one frame period and played back as the original audio signal (a). Thus, the audio is obtained as continuous signal, and the picture signal also can be obtained as a continuous signal in which one field signal is repeated for two fields.

Title: Finned heat exchanger
Inventor: OBATA MAKOTO
IPC: F28F1/32
Filed: 1985-07-05
Abstract: PURPOSE:To restrain spaces between fins from being blockaded by frost upon frosting by a method wherein slit type cuttings are arranged on the surface of the fins at gaps in the step direction of heat transfer tubes and the widths of these cuttings are shortened stepwise from the inflow direction of air to the outflow direction of the same. CONSTITUTION:The width P1 of the slit type cutting 4 is long at the air inflow path of the fin 1, therefore, the local heat transfer area of the fin 1 is small and the amount of local heat exchange is low; as a result, the thickness of frost 3 at the air inflow part of the fin 1 becomes thin. The amount of local heat exchange of cooled and dehumidified air becomes higher gradually since the widths P2, P3, P4 of the slit type cuttings 5, 6, 7 are shortened stepwise with respect to the outflow direction of air and the local heat transfer area of the fin 1 is made large; accordingly, heat exchange is effected between the cooled and dehumidified air gradually and the frost 3 is formed while the frost 3 on the surface of the fin 1 forms the layer of frost of uniform thickness. Even in such case, the space between fins 1 will never be blockaded and ventilating path may be secured widely. Therefore, the number of times of defrosting operation is decreased and comfortable property upon room heating may be improved.
