Title: Horizontal type rotary compressor
Inventor: OZU MASAO
IPC: F01C21/08
Filed: 1984-03-28
Abstract: PURPOSE:To permit lubricating oil to be efficiently supplied into a bearing part by utilizing the blade part of a compression apparatus as oil pump and allowing a coil spring extended and contracted by the urging of the blade to operate as valve mechanism and eliminating the necessity of a check valve. CONSTITUTION:When a blade 26 is moved in reciprocation by the eccentric revolution movement of a rotor 19, the blade part 26 carries-out oil feeding operation as the oil pump of an oil feeding apparatus 50. Therefore, when the blade 26 operates in the direction (upward) for increasing the capacity of a blade chamber 31, the lubricating oil stored in the inner bottom part of a casing 12 is inhaled into the blade chamber 31 through the gap of a coil spring 32 extending from a suction port 29. When the blade 26 moves downward, the coil spring 32 is contracted, and the lubricating-oil stored in the peripheral side part 42 is discharged from an oil discharge port 43 and supplied into the rotary shaft 15 of a compression apparatus 14 and a bearing 44, and sufficient oil feeding operation is permitted. In this case, the oil spring 32 performs the function of a check valve, and the necessity of a check valve in the conventional method can be eliminated.

Filed: 1992-03-16
Abstract: PURPOSE:To simplify a wiring pattern on a substrate and to reduce the size and cost of the substrate when a driving circuit IC and a display panel are connected using the substrate if the output terminal of the driving circuit IC for the panel display is in multi-pin structure. CONSTITUTION:Data input switching circuits 101-140 are controlled with a control signal SHL to switch data input paths of respective D-FFs 3241-3280. The inputted serial data Ds are shifted in the D-FFs 321-3240 to the right in order with a clock signal CP, and then moved to the D-FF 3280 and shifted in the left direction of the D-FF 3241 side. Thus, a series/parallel converting circuit 21A converts the input serial data Ds into parallel data, which are passed through a line memory 22 and converted by a row driving circuit 23 into a picture element driving signal.

Title: Facsimile transmission system and its equipment
Inventor: TSUKADA KAZUYOSHI
IPC: H04N1/17
Filed: 1990-03-09
Abstract: PURPOSE:To improve the transmission processing efficiency even through a transmission line whose line quality is deteriorated by quickening the sending speed of a picture and a scanning lines when lines of a same pattern are consecutive for a prescribed value, encoding the line of the same pattern into a prescribed pattern and sending the result. CONSTITUTION:Lines of the same pattern in a transmission original are consecutive for a prescribed line number or over, the lines are scanned while the picture scanning speed is quickened and the lines of the same pattern are encoded into a prescribed pattern and sent. Moreover, when a prescribed pattern subject to encoding is included from received information in the received picture, it is decoded and the same pattern of the output as the received picture is outputted from the lines only. Thus, even through a transmission line whose line quality is deteriorated, when same lines are consecutive, picture elements are skipped to quicken the transmission speed thereby improving the efficiency of the transmission processing.
