Title: Tape recorder
Inventor: HIRAO EIJI
IPC: G11B15/02
Filed: 1981-09-28
Abstract: PURPOSE:To record at all times a non-signal state of a specified period on a tape with a simple operation, by actuating muting function for a specified period which is set by a timer circuit after a temporary stop switch is applied, and then actuating the temporary stopping function. CONSTITUTION:A temporary stop switch 1 is applied to actuate a timer 2. The timer 2 actuates a muting circuit 3 with the control signal and simultaneously with the start of working of the timer 2. Then a non-signal state is recorded on a tape while avoiding the delivery of output from a signal amplifying circuit 5. The timer 2 delivers again the control signal when it finishes the counting of the time which is previously set by a count time setting means 8 in order to actuate a temporary stopping function 4 of the tape. At the same time, the working of the circuit 3 is discontinued, and the muting state is released. The function 4 releases the stop state of the tape when the switch 1 is opened.

Title: Extraction completion display device of extractor
Inventor: OKAMURA KENJI
IPC: A47J31/52
Filed: 1989-06-15
Abstract: PURPOSE:To visually confirm the completion of extraction by providing a container, to which a heating element is mounted, water supply pipe to guide water and water guide pipe to supply hot water to an extracting device, providing a sucking port, for which one end of the water guide pipe is opened, and a temperature sensitive thermostat on the outer surface of the container and serially connecting a neon lamp bulb, lamp resistor and the temperature sensitive thermostat to a power source. CONSTITUTION:A temperature sensitive thermostat 32 is mounted to the outer surface of a container 1, which is vertically positioned from a sucking port 8a of a water guide pipe 8, and a neon lamp bulb 33 is serially connected with a lamp resistor 34, connected through the temperature sensitive thermostat 32 to the power source and fitted to be exposed in an external part. The set temperature of the temperature sensitive thermostat 32 is set slightly lower than the temperature of the upper part in the container 1 when the extraction is completed and at a temperature less than the set temperature, a contact is opened. Thus, when the hot water in the container 1 is poured from a pouring port 8b through the water guide pipe 8, the level of the water in the container 1 is gradually lowered to the water level of the sucking port 8a. Accordingly, the temperature on the upper surface of the container 1, which is the fitting part of the temperature sensitive thermostat 33, is lowered as well. Then, since the temperature of the temperature sensitive thermostat 33 is lowered rather than the set temperature after the extraction is completed, the neon lamp bulb is turned off.
