Title: Scroll type fluid machine
Inventor: UKAI TETSUZO
IPC: F01C1/02
Filed: 1991-07-19
Abstract: PURPOSE:To prevent the generation of defective sealing caused by the deformation, damage, or the like of a sealing member by providing a passage for communicating a back pressure chamber with a high pressure chamber or the high pressure side, and additionally providing a switching valve for opening this passage when the pressure of the back pressure chamber is higher than that of the high pressure chamber or the high pressure side. CONSTITUTION:A passage 91 for communicating a back pressure chamber 40 with the high pressure side 44 is bored in a discharge cover 31, and a plate like switching valve 92 is additionally provided at a place where this passage 91. is opened to the high pressure side 4. When the pressure in the back pressure chamber 40 becomes higher than that on the high pressure side 44 (or a high pressure chamber 42) in the transient state before reaching stable operation such as the state immediately after the start of a scroll compressor, the switching valve 92 is pushed up by pressure difference between both to open the passage 91. The back pressure chamber 40 and the high pressure side 44 are thereby communicated with each other through the passage 91 so as to be placed in the uniform state and thereby to prevent a seal member 37 from being pushed toward the high pressure side 44 from the pressure chamber 40. In the state of the pressure of the high pressure side 44 being higher than that of the back pressure chamber 40, the switching valve 92 is pressed by the pressure difference between both so as to close the passage 91.

Title: Data recording system
Inventor: ONISHI YASUTOMO
IPC: G11B20/18
Filed: 1986-08-29
Abstract: PURPOSE:To prevent the breakdown of the old information data by recording the information data only in case the data pattern of each bit of the optional data is equal to a recorded one when the recorded optional data is reproduced. CONSTITUTION:A recording area for optional data FF having a fixed data pattern of each bit is secured adjacently to the recording area for information data for the recording channel of a magnetic card. Then the data FF is recorded by a magnetic head while this head moves to a return position 4 after the end of reproduction of the information data from a time point when the reproduction and collation are through with the information data. When the recording job is through with the data FF and the head arrives at the position 4, the data FF is reproduced while the head is reset to its home position 3. Then this reproduced data is processed if it is decided that the prescribed optional data is recorded. The new information data is recorded after the information processing is over. Thus it is possible to decide whether the information data can be recorded normally or not. Then the breakdown of the information data can be prevented.

Abstract: PURPOSE:To suppress the influence of power source noise by detecting the potential variation of the power source line of one or more output buffer or ground line, integrating a circuit for controlling the switching of one or more output buffers by the output of the circuit, and inhibiting the simultaneous switching of many output buffers. CONSTITUTION:When two buffers 12, 13 of three output buffers 11-13 are simul taneously switched by internal signals a2, a3 a controller is composed to delay the switching operation by the internal signal a1 of the remaining output buffer 11. A differential amplifier 21 detects the floating of the potential of a ground line 6 as a difference from the potential of a reference ground line 5, and the potential rise of the output node N1 occurs. As a result, the output node N3 of a NOR gate 3 becomes L level, is input to an AND gate 4, and the transmis sion of the output buffer 11 of the signal a1 is inhibited. Thus, the buffer 11 is avoided for the simultaneous switching with the other two buffers 12, 13 thereby suppressing the variation in the potential of the ground line 6 or higher.
