Title: Cooling and heating combination apparatus
Inventor: MARUMOTO KAZUHIKO
IPC: F25B1/00
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To realize a cooling and heating combination apparatus having a high reliability by assuring the lubricant of a compressor by reducing the discharging amount of the lubricant from an outdoor unit due to the overflow of the lubricant from an oil separator when a variable speed compressor or a constant-speed compressor is started. SOLUTION: A communicating tube 20 for communicating the discharge tube of a variable speed compressor 1 with the discharge tube of a constant- speed compressor 2 via a check valve 21 is provided. When a variable speed compressor 1 is already started and a constant-speed compressor 2 is started, refrigerant is branched to a variable-speed side oil separator 3 via the tube 20 to reduce the refrigerant speed, and the separating efficiency is enhanced to reduce the overflow. Thus, the discharge of the lubricant from an outdoor unit is reduced to assure the lubricant amounts of the compressors 1 and 2 to enhance the reliability.  A solenoid valve or a flow regulating valve is used instead of the valve 21, and this apparatus also comprises means for moving the lubricant in the bidirectional directions between the separators 3 and 4 by reducing the opening time or flow rate of the solenoid valve or flow regulating valve.

Filed: 1988-09-29
Abstract: PURPOSE:To eliminate the oscillation of a system due to a nonlinear element such as a clipper by providing a function for locking the set spectrum of an output filter by a storage means and a switching means. CONSTITUTION:The characteristics of the output filter 7 and the contents of the storage device 18 are updated according to the variation of a driving signal spectrum and when an acoustic spectrum measured value reaches a target value, a changeover switch 16 is placed on a side (b) and a switch 17 is set on the OFF side to set the contents of the storage device 18 as the characteristics of the output filter 7.

Abstract: PROBLEM TO BE SOLVED: To prevent step-disconnection in a semiconductor layer even when a gate electrode is not tapered, by forming a flattened insulating film having an upper surface smoothly connected to the upper surface of the gate electrode by removing a resist together with an insulating film formed on the resist. SOLUTION: A silicon oxide film which becomes a flattened insulating film 12 is formed on the whole surface of a gate electrode in a state where a resist is left on the electrode 11. Then the flattened insulating film 12 formed on the resist is removed by removing the resist. Consequently, the flattened insulating film 12 having an upper surface smoothly connected to the upper surface of the electrode 11 is formed. Then a silicon oxide film which becomes a gate insulating film 13 and an a-Si film 14a are formed on the gate electrode 11 and flattened insulating film 12 by continuous CVD. Since the gate insulating film 13 is formed on the flattened surface of the insulating film 12, the possibility of step-disconnection is eliminated and it becomes unnecessary to taper the gate electrode 11.

Title: Saw tooth wave generating circuit for vertical deflection
Inventor: SUMIYOSHI HAJIME
IPC: H04N3/16
Filed: 1987-09-30
Abstract: PURPOSE:To prevent a blurring phenomenon at the lower side of a screen and to project a stable picture by setting a period for comparing the amplitude of saw tooth wave voltage outputted from a saw tooth wave generating circuit at every even number time of a vertical cycle. CONSTITUTION:From a pulse generating circuit 12 for comparing a vertical amplitude, a pulse signal P13 is generated in which a pulse signal 12 is divided into 1/2. The action period of a comparing amplifier A3 is regulated by the pulse signal P13 from the circuit 12. Consequently, the circuit 12 half-divides the pulse signal P12 generated at the vertical cycle into a pulse for comparing the vertical amplitude which generates the pulse for the cycle of an 1 frame and executes the comparing action of the comparing amplifier A3 with the frame cycle. Thus, the stable picture can be projected even to a picture signal with a different field cycle in the 1 frame.

Filed: 1983-12-27
Abstract: PURPOSE:To surely prevent the deviation of an overlaid print position, by providing a means for controlling the speeds of both the side edges of a conveyed material depending on the difference between the speeds, in the direction of the conveyance of the material, to surely correct the meandering of the material. CONSTITUTION:For printing, paper P is pinched between a platen roller 12 and a pinch roller 11 and conveyed by the rotation of the platen roller. If the paper P is about to meander from the left side edge to the right side edge, torque acts to the second roller 14 of a control means 22 oppositely to the direction of driven motion of the roller due to the friction between the side of the roller and the friction plate 19 of the control means so that the roller 14 having been driven without resisting the conveyance of the paper P is braked. As a result, the frictional force between the paper P and a high-friction layer 21 acts to the paper oppositely to the direction of the conveyance of the paper so that the speed of the conveyance at the left side edge of the paper is kept from increasing. On the contrary of that, the frictional force between the paper P and the high-friction layer 21 of a first roller 13 at the right side edge of the paper acts to the paper in the direction of the conveyance thereof so that the speed of the conveyance of the right side edge of the paper increases. As a result, the paper P is prevented from meandering.
