Title: Method and device for improving image picture quality
Inventor: KAWASHIMA SUMIHIKO
IPC: H04N1/409
Filed: 1991-10-29
Abstract: PURPOSE:To remove uneven density and to emphasize the edge of an image by adding differential density between the density of an objective image and the density of an image shifted for one picture element, and defining the added density as the density of one arbitrary picture element. CONSTITUTION:For an image signal, a hold circuit 1 stores the density of a first picture element (f) in each scan line. A signal outputted from a delay circuit 2 and the source image signal are transmitted to a subtraction circuit 3, and the source image signal and the image signal delayed for one picture element are subtracted so as to calculate a contrast image. This image is integrated by an integration circuit 4 and transmitted to a gate circuit 7 and based on a signal from a timing detection circuit 5, an integrated value is outputted. The signal from the gate circuit 7 is inputted to an integration circuit 9, integrated with the density signal of the first picture element (f) in each scan line from the hold circuit 1 as an initial value, and reproduced as an extremely sharp image emphasizing the edge.

Title: Refrigerant heating type air conditioner
Inventor: YAJIMA RYUZABURO
IPC: F24D7/00
Filed: 1989-11-30
Abstract: PURPOSE:To properly secure a circulating refrigerant quantity at the startup a heating operation by conducting a pump-down operation at the startup of the heating operation. CONSTITUTION:Preheating a burner 5 is initiated at first by operation start command. When the burner 5 becomes ignitable, the operation of a compressor 1 is initiated. At this time, a solenoid valve 6 is closed. Therefore, a pump-down operation is conducted in a refrigerant circuit and a liquid refrigerant is accumu lated on the upstream side of the solenoid valve 6. After a determined pump- down operation time has elapsed, the burner 5 of a refrigerant heater 3 is ignit ed and, at the same time, the solenoid valve 6 is opened. Then, a sufficient circulating refrigerant quantity is secured from beginning of the startup of a heating operation. Therefore, even when the heating value of the refrigerant heater 3 is made maximum from the startup of the heating operation, the abnor mal overheating condition of the refrigerant at the outlet of the refrigerant heater 3 is avoided and the startup of a heating capacity is sharply speeded up.
