Title: Freezer device
Inventor: UENO AKITOSHI
IPC: F25B1/00
Filed: 1990-10-24
Abstract: PURPOSE:To prevent a reduction of freezing capacity or prevent a discharging temperature of gaseous refrigerant got from a compressor from being raised by a method wherein a control means controls a solenoid valve so as to open it during an operation of a refrigerant circuit only for a period in which oil is stored at a storing part or the oil is kept in an oil return pipe. CONSTITUTION:Gaseous refrigerant compressed by a compressor 1 and discharged from it is fed to an oil separator 3. The oil separator 3 is constructed such that a storing part 23 for storing separated oil is provided and the oil passes from an oil discharging hole 25 at a lower part of the storing part 23 through an oil return pipe 14 and a solenoid valve 15 placed in the midway of the oil return pipe and returned back to the compressor 1. This solenoid valve 15 is opened only for a period in which the oil is stored at the storing part 23 of the oil separator 3 under an operation of a control means 26 or in which the oil is present within the oil return pipe 14. Accordingly, it is possible to prevent the gaseous refrigerant discharged from the compressor 1 from being short-circuited at the oil separator 3, solenoid valve 15 and oil return pipe 14 to a suction line of the compressor and from flowing. Due to this arrangement, it is possible to prevent a freezing capacity from being reduced or a temperature of the gaseous refrigerant discharged from the compressor from being raised.

Title: Printer
Inventor: TANAHASHI MAKOTO
IPC: H04N5/765
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To improve the print quality of the printer compositing a graphic image and characters onto a video input image and printing the synthesized image in which the respective images are not sacrificed with each other. SOLUTION: In addition to superimposition of a video output onto a monitor or the like by a superimposing section 19, superimposition of an image to be printed is made by a print control section 23. The print control section 23 allocates different number of dots per one pixel to a video input image, a graphic image and characters or the like on the same print sheet respectively. Thus, different number of dots is allocated to one pixel of the video input image, the graphic image and the characters or the like. For example, lots of dots are allocated to the pixel of the video input image part to attain multi- gradation expression and small number of dots are allocated to the graphic image part because of less number of sets of gradation to attain high definition expression.

Abstract: PURPOSE: To sufficiently dissipate heat from a semiconductor element by simple constitution without deteriorating the reliability of a device, by mounting a semiconductor element in contact with an L-shaped bent part formed by bending a flat plate of metal, and mounting the L-shaped component on the surface of a printed board. CONSTITUTION: Almost all the surfaces and backs of flat plates 21, 22 of metal and an outer leg part 23 act as heat radiation fins. The metal surface part of a semiconductor element 11 is formed on the side in contact with the flat plate 21 of metal, which is electrically connected with the semiconductor element and mechanically bonded, by interposing a thin solder layer as the intermediate. The outer leg part 23 and the board 13 side of a lead 12 are in contact with board patterns 14, 15, and the contact parts are soldered. As the result, heat dissipation is improved, so that operation range can be enlarged as far as the vicinity of the limit value of the electric characteristics of the semiconductor element 11.  Since the temperature of the semiconductor element can be kept adequate and heat dissipation is excellent, long life and high reliability are realized in semiconductor element operation.
