Abstract: PURPOSE:To easily judge the propriety of an installation place, by providing a reception condition pilot lampwhich flashes in the reception of a radio wave. CONSTITUTION:A radio wave arriving through an antenna 1 is demodulated by a reception part 2. It demodulation output is supplied to a selective calling  part 3 to detect a selective call signal. When a selective call signal addressed to  its station is detected, the output of the reception part 2 is connected to a  speaker 4. At this time, when the radio wave is received, the reception part 2 outputs a DC voltage discriminated from that when no radio wave is received,  namely, a squelch voltage signal to an output line 9 without reference to the  presence of the selctive call signal. On receiving the squelch voltage signal from  the output line 9, a low frequency oscillating circuit 7 starts oscillation and supplies its output to a light emitting diode 6, which flashes.

Abstract: PURPOSE:To equalize the temperature distribution of tube wall as well as reduce the temperature of the tube wall by eliminating the occurrece of vortex flow on the downwind side of high-pressure discharge lamp by providing a flow regulator between the exhaust port of a reflector and the downwind side of the lamp. CONSTITUTION:A flow regulator 15 is set on the exhaust port 13 side of a reflector 2 on the surface of the downwind side of a high-pressure discharge lamp 1. As air is discharged from the port 13 by a sucker, cool air is flowed into an irradiating port 3 and flows along the surfaces of the lamp 1 and also of the reflector 2 while cooling them. The air flows along the regulator 15 from the surfaces of the lamp 1 and the reflector 2 to the exhaust port 13 and then the controlled air flowing through both sides 16 of the regulator 15 from both sides of the lamp 1 is joined and discharged. Since air controlled by the regulator 15 flows near the surface of the downwind side of the lamp 1, no vortex flow of air occurs.

Title: Collecting device for solar heat
Inventor: HATSUTORI MASAJI
IPC: F24S90/00
Filed: 1979-05-22
Abstract: PURPOSE: To simplify the electric circuit and also to save labor for construction works by a system wherein a circulating flow detector for a heat medium is provided on a part of a collected heat circulating circuit, and a circulating pump is controlled to stop when it runs at a rate less than set point.  
     CONSTITUTION: Where the heat medium level is over a line 14 in a tank 6 and a normal operation is carried out, a differential temperature thermostat 8 operates, a switching contact 8' is closed and a circulating pump 4 is conducting. A timer 9 is also conducting at the same time and changed to a transfer contact 9b after a given period of time, however, since a differential pressure flow detector 7 indicates a rate more than a set point, a switching contact 7' is left closed, and the operation is kept going. However, when the level comes down to a line 15, it is necessary to lift the heat medium as high as a head H, and since the flow rate comes below the set point, the switching contact 7' is opened to stop the pump 4, and an alarm is given for abnormity. The heat medium is replenished, and a fault is prevented. An electric circuit and construction works are thus simplified.
