Filed: 1985-07-16
Abstract: PURPOSE:To recognize easily miniaturization of circuit scale and a display slave screen picture source by providing a means for synchronizing a write request pulse with an address switching pulse to use only a field memory as a memory element. CONSTITUTION:In writing slave pattern data, a write request pulse (e) is obtained periodically from a decoder 28 decoding an output of a write counter 22. The pulse (e) is synchronized with the slave pattern data and fed to a clock input terminal of D type FF29 via a write request pulse switching circuit 43. An output (k) of the FF29 is inputted to a D FF30 and the inverse of output (e) is fed to a OR gate 25 together with an address switching pulse (b) of an address switching circuit 42. Thus, an output (n) of the gate 25 is synchronized with the pulse (b) and when the output (n) is at a low level, a write address is outputted from the circuit 42 and a field memory 21 is in the write state. Thus, only the memory 21 is enough as the memory element, the circuit scale is miniaturized and the source of the display picture is recognized easily.

Abstract: PURPOSE:To prevent such a trouble that water in a bathtub intrudes into heated water in the hot water apparatus by providing a pressure closing valve having a diaphragm facing an atomspheric pressure in a pipeline on the side connected to the can body. CONSTITUTION:A valve seat 20 is formed on one end of a pipeline 9'' connected to the can body 1, and a diaphragm 12 one end of which faces the valve seat 20 and another end of which faces the atmospheric pressure is provided. The water pressure of service water supply is applied on the diaphragm 12 of a pressure closing valve 13 from pipelines 9 and 9' as a pressure of 0.6kg/cm<2> even when a pressure reducing valve 18 is interposed therebetween. Since the other side of the diaphragm 12 confronts the atmospheric pressure, it moves and is held at a position separated from the valve seat 20. In the above described construction, the pressure of the service water is constantly applied on the can body 1, pipelines 9 and 9' and the radiator. Even when any pore-generation occurs in the radiator, water in the can body 1 folws out of a heat exchange chamber, and ordinarily there is no possiblility that water in the bathtub intrudes into the radiator (can body 1).

Abstract: PURPOSE:To improve the permeability of a magnetoresistance effect film by successively and continuously forming four layers composed of magnetoresistance effect films, intermediate layer put between the magnetoresistance effect layers, and protective layer under a heating and reduced-pressure condition. CONSTITUTION:After a prescribed substrate is set in a vapor-depositing device, the device is evacuated to a vacuum state and, at the same time, the device is heated to 250 deg.C. When the degree of vacuum in the device becomes <=3X10<-5>Pa, vapor deposition is started. Then an intermediate layer is formed on a first MR film formed in the same vacuum device after the first MR film is formed on the substrate in the vacuum device. After the intermediate film is formed, a second MR film is formed by vapor-depositing NiFe to a thickness of 30nm. Finally, protective layer is formed by vapor-depositing alumina to a thickness of 20 nm. Thereafter, the substrate is taken out from the vapor-depositing device after cooling the substrate to about a room temperature. Thus all vapor-depositing processes are continuously and successive performed in the same vacuum device. Therefore, the permeability of a magnetoresistance effect element thus manufactured is improved as compared with the conventional example and, as a result, the reproducing sensitivity of the element can be improved.
