Filed: 1988-05-30
Abstract: PURPOSE:To promote the circulation of refrigerant and upgrade the effect of heating with a heat transfer capacity and high temperature air of a radiator, by installing a part of connection pipe which connects a gas section of an air/liquid separator with a radiator in such a manner that it may be placed into contact with a refrigerant heater. CONSTITUTION:On the way of piping 9 which connects a radiator 6 with an air/liquid separator 3, a refrigerant, which is heated and vaporized by a burner of a refrigerant heater 1 installed below the air/liquid separator 3 by a contact section 10 to be heated again from a refrigerant heater 1, flows into the air/liquid separator 3 under sufficient two phase state from the lower end of the refrigerant heater 1. The heat transfer effect produced by the heat exchange between the refrigerant heater 1 and the contact section 10 minimizes piping resistance, which makes it possible to reduce the size of an inlet pipe 8 and a rising pipe 7. The refrigerant present in the piping 9 is turned into perfect gas phase, responding to the pressure of the refrigerant in the piping 9. The heat transmission in the radiator 6 is further increased in order to send the gas to the radiator 6 as a superheated gas. The quantity of refrigerant to be circulated is accordingly reduced. It is, therefore, possible to reduce the size of piping 9 and the cost as well, and obtain high temperature hot air from the radiator 6.

Title: Data output buffer with clamping function
Inventor: CHIYOU HORETSU
IPC: H03K19/017
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To conduct clamping after step-up voltage reaches a sufficient level, and to stabilize a high data output regarding a data-output buffer having a clamping function outputting data by clamping and outputting stel-up voltage. SOLUTION: An initial step-up data signal DOKI is transmitted to a transistor 84 and the transistor 84 is turned off before the transistor 84 is turned on and a step-up data signal DOK is clamped. A transistor 77 is tuned on after a fixed time passes after a transistor 81 is tuned off. Since Vcc is transmitted to the gate of the transistor 84 and the transistor 84 is turned off in conventional devices, the situation, in which the transistor 84 is conducted and clamped and a level is in short supply before the step-up data signal DOK is stepped up sufficiently when the signal DOK begins to be stepped up and applied, is generated, but the situation is solved because the transistor 84 is controlled with the initial step-up data signal DOKI higher than the same level as the step-up data signal DOK.

Abstract: PURPOSE:To attain the recording/reproducing characteristics equivalent to an auxiliary magnetic pole exciting system with a main magnetic pole exciting system, by obtaining two-time differential waveforms of the output of a magneto-resistance effect type magnetic head when the information written to a vertical recording medium of a compound double-layer film recording medium and detecting the zero cross point of said differential waveforms. CONSTITUTION:The information is written to a compound double-layer film recording medium 6 by a unipolar type recording head 1 and then reproduced by a magneto-resistance effect (MR) type magnetic head 11. In this case, an isolated reproduction waveform similar to a function tan<-1> is obtained. Then a differential waveform (Fig. a) of said isolated waveform is obtained, and the effect of the DC component of said differential waveform is eliminated. This differential waveform is differentiated again to obtain a waveform (Fig. b), and the zero cross point of said waveform is detected. Therefore the zero cross point is detected for said isolated reproduction waveform. When the information is read out by the head 11, a sense current is supplied to the head 11. As a result, the resistance change of the head 11 due to the magnetic field of a vertical magnetic recording medium 3 is converted into a voltage change. This voltage is amplified by a preamplifier 13 and then differentiated two times by the 1st and 2nd differentiation circuits 14 and 15 to be supplied to a zero cross point detector 17 via an LPF16 for detection of the zero cross point.

Abstract: PURPOSE:To omit data transfer between a main storage part and an expanded storage part and to shorten processing time by switching an address space in the main storage part to an address space in the extended storage part, and after processing data, switching the address space again to the original one in the main storage part. CONSTITUTION:When a processing request for data D stored in the expanded storage part 3 is generated in a program C, the program C calls a program A in the main storage part 2 and outputs a processing request for a program B and the program A in the main storage part 2 switches the control of a central processing part 1 from the address space AS1 in the main storage part 2 to the address space AS2 in the expanded storage part 3. Since the same image is stored in the same address of both the main storage part 2 and expanded storage part 3, the program A can execute continuous processing during the switching of these storage parts. After the end of switching, the program A in the expanded storage part 3 calls the program B to request processing relating to the data D. The program B processes the data D, and after the end of the data processing, returns its control to the calling program A in the expanded storage part 3.

Filed: 1983-07-19
Abstract: PURPOSE:To form a circuit without using an expensive switching element such as an FET etc. by limiting the base current of a transistor for controlling and making switching in an active area. CONSTITUTION:A voice input signal A is outputted as an emitter follower output through a transistor (TR) 14. When a control signal is applied to the base of a TR18 through a high resistance 20, the TR18 conducts. Acoordingly, the voice input signal A and another voice input signal B are synthesized in the common emitter of the TR14 and TR16 and outputted. When the control signal is not applied to the base of the TR18, the TR18 becomes a cut off state and the voice input signal B is not transmitted to the TR16 and only the voice input signal A is outputted. Accordingly, voice mixing becomes possible without using the expensive switching element such at the FET, etc.
