Title: Refrigerating device
Inventor: AOKI TAKESHI
IPC: F16K31/06
Filed: 1988-02-19
Abstract: PURPOSE:To improve the response property of the opening and closing of an electric expansion valve, by a method wherein a pulse width modulating signal with a proper frequency, avoiding the resonance frequency of a spring, is produced based on the signals of a temperature sensor and a temperature setting unit while a valve opening degree regulating unit, which controls the opening degree of the valve by the pulse width modulating signal, is provided in the title device. CONSTITUTION:A valve opening degree regulating unit 15 receives signals from room temperature sensors 10, 11 and a temperature setting unit 20, setting the room temperatures at desired temperatures, and produces a pulse width modulating signal, in which an ON/OFF duty ratio is changed based on a relation between these signals, to control a refrigerant flow rate control valve 14. The refrigerant flow rate control valve 14 is provided with a characteristic, in which the hysteresis width of a magnetic core, magnetized by a solenoid constituting a part of the valve 14, is increased with respect to the smooth change of an impressing voltage, and the hysteresis width of the same becomes wider with respect to a periodic change as the period of the same becomes shorter, while this characteristics is one of reasons to delay the response property of valve opening degree changing with respect to a signal. Therefore, the frequency of the valve opening degree regulating unit 15 is set based on the consideration of the resonance frequency of a spring when the impressing voltage is changed periodically, in order to make the hysteresis width small.

Filed: 1993-02-26
Abstract: PURPOSE:To perform a measurement with high accuracy without being affected by a hysteresis by a method wherein the discrimination means of a change direction is installed and a beam is set in an equilibrium state always from one direction. CONSTITUTION:When a load on a weighing pan is increased or decreased, a beam is changed, and a nonequlibrium state is detected by a beam-position detection means 20. The displacement amount of the beam by a signal from the means 20 and information on whether its change is an increase or a decrease in the load are stored in a microcomputer 4. Then, an electromagnetic force P generated at a point of time when the load on the weighing pan has been changed and an equilibrium electromagnetic force N which has been computed from the electromagnetic force and from the change amount of the beam and which is required to obtain a new equilibrium state are stored in the computer 4. Then, even when the electromagnetic force P is brought close to the electromagnetic force N, they are not brought to an equlibrium state, the electromagnetic force P is once decreased excessively, and the electromagnetic force P is increased gradually at the unit of a change in an electromagnetic force. When the difference between the electromagnetic force P and the electromagnetic force N becomes the unit of the change in the electromagnetic force, the difference between the electromagnetic force P and the electromagnetic force N is added, and they are brought to the equlibrium state.

Abstract: PURPOSE: To improve durability by reducing the deposition of carbon on the inner surface of a wall within an oven, by a method wherein a calcined coating layer consisting of an inorg. binder and particle contg. silicon carbide particle, silicon nitride particle or graphite particle, is formed on the surface of a lining refractory.  
     CONSTITUTION: A calcined coating layer consists of a matrix part 14 composed of an inorg. binder and a particle part composed of 10W100wt% (based on the combined weight of particles) of a member 12 contg. at least one selected from silicon carbide particle, silicon nitride particle and graphite particle and 90W0wt% of an oxide refractory particle 13. The calcined coating layer is formed on the surface of a lining refractory 8 of at least one member selected from an oven lid 1, a riser 2 and a lime charging port 3. The reason for which the graphite particle, etc. are used within the range of 10W100wt%, is that, when below 10wt%, it is not sufficient to prevent the deposition of carbon but it is of no practical use. The silicon carbide, etc. are more difficult of obtain than the oxide refractory. Hence, it is preferred to use 0W90wt% of the oxide refractory instead of the silicon carbide, etc.

Abstract: PURPOSE:To simplify the construction by applying a fixed voltage to the input of the integration circuit of voltage proportional to the received signal level from target object through the antenna in a specified delay time from the start of rotation of the antenna driving motor. CONSTITUTION:A voltage A which is proportional to the received signal level after the detection 3 of the signal received from the target object through the antenna 1 is added by an addition circuit 5 with the output B inverted through a sample hold integration circuit 4. When the output C of the circuit 5 is below the given voltage or above the specified voltage in the opposite polarity, it is fed to comparators 6 and 6'. The rotation detecting signal from the circuit 6 and 6' is fed to a monostable multivibrators 7 and 7' for forming a delay time to produce the gate output of delay range. The output of the mono-stable multivibrators 7 and 7' is added to allow the sample hold switch S1 to be driven whatever output is detected. The output D of the monostable multivibrator 7' is fed to a reverse change-over circuit 9 of the antenna driving motors 15 and 16 whose output causes the switches S2 and S3 to be changed over through AZ/EL switching circuit 10. Thus, a specified integrating voltage is fed to the circuit 4.
