Title: Pulse width modulation circuit
Inventor: TSUJI KIMIHISA
IPC: H03K7/08
Filed: 1991-04-26
Abstract: PURPOSE:To suppress an error in a load current due to fluctuation in a power supply voltage over wide range of an input signal by with respect to the pulse width modulation circuit outputting a pulse width modulation signal whose duty ratio is varied with an error in the input signal. CONSTITUTION:An arithmetic means 102 generates a signal in response to a product between a fluctuation of an input signal from a reference value and a fluctuation of a power supply voltage from a reference voltage. A level variable means 104 uses an output signal of the arithmetic means 102 to change an output error signal of an error amplifier 101 and a relative level of an output slope of a slope wave generating circuit 103. A comparison means 105 generates a pulse width modulation signal.

Title: Air conditioner
Inventor: OISHI TETSUSHI
IPC: F24F11/02
Filed: 1987-04-21
Abstract: PURPOSE:To enable suitable sensing of a room temperature and its control to be performed by a method wherein a lower sensed temperature signal of a suction air temperature sensor and a blowing air sensor is selected and controlled. CONSTITUTION:When a heating operation is stopped, a blower 4 is stopped, so that air around a heat exchanger 6 is heated by a hot coolant within a pipe passage 6a in which the thermal medium stored in a heat exchanger 7 flows or its surplus heat through plate-like fins 6b even if the hot coolant is not circulated, an ascending air flow is generated due to a difference in temperature with the surrounding air, resulting in that a suction air temperature sensor 3 is heated and so a proper room temperature can not be detected. In this case, a signal sent from the sensor device 3 within a room temperature control device is compared with a signal sent from a blowing air temperature sensor 9, and the room temperature control device is set in advance so as to discriminate the lower temperature as a room temperature, resulting in that it is possible to sense always proper room temperature without being influenced by the heat exchanger 7 and so air conditioning operation expected by a user for its predetermined temperature can be performed.

Title: Method of measuring flow velocity or rate
Inventor: UEMATSU MAKOTO
IPC: G01P5/00
Filed: 1979-07-31
Abstract: PURPOSE: To measure the velocity or rate of flow independently of the roughness of the wall of a water passage and its size, by setting such a partial flow detection position that a formula for converting the partial flow velocity into the mean flow velocity is a function of only a diameter depth ratio which is defined by only the shape of the cross section of the water passage.  
     CONSTITUTION: Ultrasonic flow velocity detectors 2, 3 are provided on the inside wall of a circular water passage 1 so that the detectors faces each other. The mean flow velocity between points P, Q is detected and applied to a flow velocity converter 4. An ultrasonic water level detector 5 is installed over the water passage to detect the water level in the passage. The detected water level is applied to a water level converter 6. The output signals of the converters 4, 6 are transmitted to a calculator 7, which computes the mean flow velocity on the cross section of the water passage from the mean flow velocity between the points P, Q and the water level multiplies the mean flow velocity on the cross section of the passage by the cross- sectional area of the passage to produce a flow rate signal 8. The partial flow velocity detectors 2, 3 are located at such a depth that the ratio of the mean flow velocity to the partial flow velocity is a linear function of the one-sixth power of the diameter depth ratio.
