Abstract: PURPOSE:To effectively produce a low noise area by a method wherein in a compressor wherein a lead valve opened and closed according to a differential pressure is located in a through-hole through which low and high pressure areas in the compressor are respectively communicated with a compression chamber. CONSTITUTION:In a volume type compression chamber, the outer end of a cylinder block in which a plurality of compression chambers (bores) 1a are disposed is sealed by a housing with a valve plate 2 nipped therebetween. A delivery hole 5a through which a delivery chamber (a high pressure area) 5 and the compression chamber 1a are intercommunicated is formed in the valve plate 2, and a plurality of lead valves 7a corresponding to the respective delivery holes 5a are mounted on the other valve seat surface of the valve plate 2 exposed in the delivery chamber 5. In this case, the valve seat surface 2a is covered with fluorine resin film 10 and the resin film 10 is formed in a shape in which only an annular region P embracing the periphery of each through-hole 5a is notched. This constitution forms interference stepped parts P1 and P2 to disturb plane contact between the valve seat surface 2a and the lead valve 7a formed on both sides of an axis X extending astride the through-hole 5a.

Title: Electrophotographic device
Inventor: OTOSHI MEGUMI
IPC: G03G21/00
Filed: 1993-12-16
Abstract: PURPOSE:To provide a negative/positive developing system electrophotographic device having a high-quality image and stable separation performance by a transfer and carrying belt system by providing a bias impressing member imparting electric charge on a more downstream side in a carrying direction than a nip part between a transfer and carrier belt and a photoreceptor. CONSTITUTION:The transfer and carrier belt 20 is wound around a driving roller 21 and a driven roller 22 and made to run counterclockwise. At an action time, the belt 20 is made in press-contact with the photoreceptor 1 and the nit part 26 sliding between the roller 22 and an impressing roller 23 by proper width is formed between the photoreceptor 1 and the belt 20. At the nip part 26, a paper on which a toner image is formed is made in press-contact with the photoreceptor 1. However, the paper is electrically attracted by the belt 20 when it goes out from the nip part 26 and separated from the photoreceptor 1. At this time, since the roller 23 is provided at a position where the paper on the downstream side in the carrying direction of the paper is separated, attraction force between the paper and the belt 20 becomes strong at an area where the paper is separated from the photoreceptor 1 and the separation performance is enhanced without deteriorating transfer property.

In such a case, the liquid crystal layer 21 contains polymerized molecules. The film thickness (d) is made larger than the spiral pitch of the unpolymerized liquid crystal layer in the state of having no cells.  As the process for manufacturing the liquid crystal cell, the ferroelectric liquid crystal mixture in an unpolymerized state is packed into the previously prepd. cell and is illuminated with light of the same intensity from both sides in order to polymerize the cell. Symmetrical alternate voltages are impressed on the cell during the time of the polymn. treatment.

Title: Vacuum cleaner
Inventor: KAWAMATA MITSUHISA
IPC: A47L9/28
Filed: 1989-12-08
Abstract: PURPOSE:To save useless energy and to decrease noise by providing a means for detecting static pressure and a load current in an operating state, and deciding that cleaning is not executed or a suction port is sucked to the surface to be cleaned unless the detection quantity is fluctuated for a prescribed time, and lowering the suction force. CONSTITUTION:A detection value H detected from a pressure sensor 10 having a detecting part in a body passage is transmitted as a signal to a control circuit 9, and the control circuit 9 decides that cleaning is not executed at pressure or a suction port is sucked to the surface to be cleaned unless its detection value H is fluctuated in a prescribed period, and lowers the speed of revolution of a motor-driven air blower 2. In this case, simultaneously, the control circuit 9 decides that the suction port 8 is in a sucked state and a non-cleaning state, when the detection value H from the pressure sensor 10 is larger than or almost the same as an average value H0 of the detection value at the time of cleaning executed immediately before, and reduces the suction force by lowering remarkably the speed of revolution. When  H>=0 or an absolute value ¦ H¦ of  H is smaller than a prescribed value (a), power is lowered remarkably, comparing with the time of a state of A, and in addition to an effect of energy saving and a noise reduction, overheating of the motor-driven air blower 2 caused by suction of the suction port is prevented.

Title: Recovery braking apparatus for vehicle
Inventor: TABATA ATSUSHI
IPC: B60L50/16
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To attain continuous deceleration feeling through reduction of down- shift during the recovery braking, by opening a little a lockup clutch or setting it to the half-engaging condition when down-shift is performed during the recovery braking, and then accelerating rotation of a motor generator for synchronization with the number of rotations of an input shaft of a transmission. SOLUTION: A signal for increasing the number of rotations of a motor generator 3 is outputted toward a controller 42. The number of rotations of motor generator 3 becomes higher than that after change of the number of rotation owing to the down-shift but it is raised in the side of motor generator 3 before it is forcibly raised with a torque of drive wheels from the transmission side after the down-shift. As a result, difference in the number of rotations when the output shaft of motor generator 8 is engaged with the input shaft of the transmission is canceled to prevent generation of shop due to the down- shift. The lockup clutch is re-engaged after confirming that the number of rotations of motor generator 3 is synchronized with the number of rotation of the input shaft of transmission after the change of number of rotations.

Title: Information communication system
Inventor: TAKAGI MITSUO
IPC: H04M11/00
Filed: 1987-12-15
Abstract: PURPOSE:To immediately inform a user program means when a circuit condition changed without lowering the processing capacity of the whole system by checking a circuit condition by the transmission/reception of a test message to a terminal and a computer system periodically. CONSTITUTION:A diagnostic device 105 sends a terminal test message to terminals 110 and 112 by a terminal supervision request outputted when an input/output service means 102 receives an input request from a user program means 101, examines whether a response message from the terminal is proper or not, and checks a circuit condition. The checking is repeated at every fixed period. Consequently the checking of the circuit condition is practiced when the user program means 101 does not make access to the terminal 101 and the computer system 112 or when the message is inputted from the circuit. Thus, the user program means can be informed immediately when the circuit condition changes without generating the lowering of a system processing capacity.
