Title: Data transfer device
Inventor: KUSHIDA SADAAKI
IPC: G06F13/36
Filed: 1988-04-19
Abstract: PURPOSE:To execute a transfer at a high speed and with high efficiency and to shorten the bus exclusive time by compressing and converting data to be transferred to prescribed bit length data, sending it out successively onto a bus, bringing input data from the bus to reverse conversion and reproducing pre-conversion data. CONSTITUTION:A data transmitting circuit 10 is constituted of means 13-15, and the means 13 converts transfer data to a format which has justified a null generated by being delimited by prescribed byte width. The means 14 sends out the transfer data whose format has been converted to a bus 11, and its sending-out is executed by setting the number of bytes as a unit. The means 15 gives data whose contents are a data correspondence relation before and after the conversion to a data receiving circuit 12. On the other hand, a circuit 12 is constituted of means 16-18, the means 16 inputs the data from the bus 11, and the means 17 receives the data whose contents are the data correspondence relation before and after the conversion. Also, the means 18 brings the input data to reverse conversion by using the received data, and reproduces the data before the conversion. In such a way, the transfer data quantity can be increased, the number of times of a transfer and a start can also be curtailed, and the bus exclusive time can be shortened remarkably.

Title: Hermetic electric compressor
Inventor: YAHIKI JIYUNICHIROU
IPC: F04B39/00
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To eliminate collision of both the metal of a sealed container and of a block, and prevent generation of metallic powder and metallic noise by arranging a part composed of a shock absorbing material which abuts on an inner wall surface of the hermetic container, on an outer peripheral surface of the block for forming a compression element. SOLUTION: An abutting part 31 is disposed on an upper surface of a cylinder, in a compression element 3 of this hermetic electric compressor apart from an upper cover inner wall ceiling surface of a sealed container for prescribed clearances. A plurality of abutting parts 32 are disposed on an outer peripheral part of a block 26. When vibration and sliding is generated, having a constant magnitude at transporting or starting of an electric compressor, for example, the abutting part 31 abuts on the sealed container in the case of sliding in an upward direction, the abutting part 32 abuts on the hermetic container in the case of sliding in a horizontal direction, and thereby, shock is absorbed and sliding more sliding is also suppressed. Since both abutting parts 31, 32 abuts so as to release and absorb the shock, uncomfortable metallic noise will not be generated.  Since this is not an abuttment of both metals against each other, generation of metallic abrasion powder is reduced.

Title: Detecting method for different mixing frequency in electric power source of ac feeding circuit
Inventor: TORII MASAHARU
IPC: G01R31/00
Filed: 1988-04-21
Abstract: PURPOSE:To make a decision speedy for an existence of a closed mixing frequency by sampling with a 600Hz the mixing frequency closed to 50Hz and 60Hz of an AC feeding circuit and converting instantaneous values of 50Hz and 60Hz components obtained by specified arithmetic operation to the respective root-mean-square values then comparing with setting values. CONSTITUTION:The mixing frequencies closed to 50Hz and 60Hz of the AC feeding circuit are sampled with the 600Hz frequency. Next, a digital value before 5 sampling is added to the sampling digital value and the instantaneous value of the 50Hz component is obtained in the result of dividing by 2Xcos(5pi/12). Also the digital value before 6 sampling is added to the sampling digital value and the instantaneous value of the 60Hz component is obtained in the result of dividing by 2Xcos(1.2pi/2). These instantaneous values are converted to the root-mean-square values by double products method, etc., then compared with the setting values in the manner that the 50Hz and 60Hz frequency components are made to be the operating elements. Thus, the existence of the closed mixing frequency can be measured in a short time.
