Title: Circuit for demodulating supervisory control signal
Inventor: FUJIWARA HARUO
IPC: H04L25/02
Filed: 1985-02-25
Abstract: PURPOSE:To demodulate properly a supervisory control signal by passing the output of an FF through a window comparator after said output passes through an LPF having an interrupting frequency lower than a carrier frequency. CONSTITUTION:A transmission signal from a discriminating part is inputted to the FF1. A part where an odd parity is inserted at every L-number of bits of the output can obtain a signal having a mark ratio error changed by the frequency of the carrier frequency f. The output of the FF1 passes through the LPF 8 whose interrupting frequency is lower than the carrier frequency of the output of the FF1, and the value of the part where the odd parity is inserted at every L-number of bits comes to the mean of two-types of mark ratio values which said part can take when the odd parity is not inserted. This value is not changed in a level depending to an error. Moreover, in terns of the value of the part where the odd parity is not inserted, its mark ratio value is changed due to the error, however it takes either one of said two mark values. Its output is amplified 9, and the window comparator 10 discriminates low and high thresholds, thereby outputting a demodulated value.

Filed: 1979-03-27
Abstract: PURPOSE:To respond more accurately to the variation of load when winding a wire around the shaft and fixing one end to the shaft while projecting the other end from the shaft to use as load supporting portion. CONSTITUTION:Automatic refrigerator management equipment is constructed such that when such as drinks 26 is taken in or out from one of many containing chambers 13, a receiving member 2 associated to each containing chamber 13 moves up and down against a spring 8 to turn on, off a lead switch 22 through a magnet 23 integrated with the receiving member 2 thus to detect the taking in or out.

Abstract: PURPOSE:To miniaturize the element shape free of mismatching in mask positioning and with narrowed width of ring, by selectively etching only the surrounding portion of the mask used in the previous process to utilize as the mask for forming guard ring. CONSTITUTION:An N<+> type buried layer 2 and an N type epitaxial layer 3 are formed on a P type Si 1, applying Si3N4 mask 4 thereon and after etching the layer 3, SiO2 film 5 is formed by oxidation.

IPC: F24D3/00
Filed: 1988-02-18
Abstract: PURPOSE:To control an interior part so as to get a comfortable condition by a method wherein an indoor machine is kept at a rated capability with rated values of a pressure and a flow rate within a heat exchanger irrespective of an installing condition. CONSTITUTION:A pressure sensing means 3b is arranged at a hot water inlet port of an indoor machine 3 and a hot water flow rate controlling valve 3a is arranged at one end of a heat exchanger 3a of the indoor machine 3. A pressure value sensed by the pressure sensing means 3b is inputted to a valve driving and controlling means 3e.

Title: Electronic balance
Inventor: TSUJI TOSHIHIRO
IPC: G01G7/02
Filed: 1985-02-25
Abstract: PURPOSE:To automatically turn off an electrical source when the balance is out of use for longer than a predetermined time period to reduce power consumption by using a constitution in which the power source is automatically turned off when the load detection data remains near zero for longer than a predetermined period and again turned on upon actuation of a tare deduction command key. CONSTITUTION:When a near-zero value is supplied after turning on of a power switch 7 to a control part 3 from a load sensor 1 through an AD converter 2, the control part 3 judges that the balance is in a non-use state and transmits a judgement result signal J to an FF 12b of a power source on/off control circuit 12. The FF sends a low level control signal C to a contactless AC relay 11 which is automatically turned off so that the power supply is terminates by a main current circuit 9. On the other hand, upon actuation of the tare command key 5, reset signals are sent to the FF 12b from the control circuit 3 so that the signal C goes to H level to turn on the relay 11 to again initiate power supply from the circuit 9.
