Abstract: PURPOSE:To unnecessitate a member used exclusively for feeding lubricating oil, by employing such an arrangement that a groove formed in a vane is communicated with an opening of an oil passage at least when the vane is most protruded from a cylinder toward the center of a cylindrical compression chamber. CONSTITUTION:Part of a groove 11 formed in a vane 9 at its surface held in contact with a second frame member 5 is always immersed in oil 12. Further, an oil passage 13 is formed in the second frame member 5 such that one end of the oil passage 13 is opened in a lubricating section 14 while the other end is opened on the sliding path of the vane 9 in its surface kept in contact with the vane 9. Here, arrangement is such that the groove 11 and the oil passage 13 are communicated with each other when the vane 9 is most protruded from a cylinder 6 toward the center of a cylindrical compression chamber but the groove 11 is not communicated with the oil passage 13 when the extent of protrusion of the vane 9 is less than at least half of the maximum protrusion of the vane 9.

Title: Difference current generation circuit
Inventor: SHIMIZU TAKESHI
IPC: H03F3/343
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide the difference current generation circuit of relatively simple circuitry operatable by low voltage power supply since the four pieces of transistors are vertically piled up, an operation when a power supply voltage is the low voltage of about 3V is difficult and an element number is large in the case that a circuit for generating a signal current is a double balanced mixer type in a conventional difference current generation circuit. SOLUTION: A current I8 flowing to a load resistor RL is indicated by the following expression. The expression is defined as I8 =I6 -I7 ≈I6 -I5 ≈I4 -I3 = I0 '-I0 -I1 I2 . Also, since it is I3 =I0 and I4 =I0 ' when I1 =I2 =0 because of current mirror constitution, I9 ≈I0 ≈I0 ' is attained. Thus, the current I8 flowing to the load resistor RL becomes the difference current of the signal currents I1 and I2 and is taken out as a voltage centering a reference voltage VREF. This circuit is constituted by vertically piling up the three pieces of the transistors between a high potential side power supply terminal and a low potential side power supply terminal even when the double balanced mixer whose collector load resistor is resistors R1 and R2 is connected.

Abstract: PURPOSE:To set an effective picture area at a maximum while securing separation from a photoreceptor, by equipping a guide part which floats the leading-edge corner part of a transfer material over a photosensitive surface and a hooklike bending member for the leading-edge corner part of the transfer material. CONSTITUTION:A transfer material separator consists mainly of a transfer sheet leading-edge corner bending member having a hook part 64 composed of a guide part and an arc part, and a transfer sheet catching and peeling member like a peeling pawl 36. Then, said bending member bends only a leading-edge corner part of a transfer sheet so as to float it for a photoreceptor surface before transfer processing and the catching and peeling member catches the bent leading-edge corner part and peels the transfer sheet off from a photoreceptor surface after the transfer processing. Therefore, an effective picture area is set at a maximum in comparison with a conventional separator which uses a pick-off belt 9.

Filed: 1995-03-20
Abstract: PURPOSE: To smoothly shift an automatic transmission and prevent shift shock by shifting another shift stage after executing clutch-to-clutch shift to a shift stage in the adjacent to its shift stage in the case of skip upshifting from the shift stage, which is set without using a one-way clutch. CONSTITUTION: When skip shift from the second speed to the forth speed is judged based on that, for example, vehicle speed is increased in traveling at the second speed gear or a throttle opening is abruptly reduced, the third brake B3 is released by switching a 2-3 shift valve 71 and at the same time upshifting from the second speed to the third speed is executed by clutch-to-clutch shift for engaging the second brake B2. When it is judged that the upshift to the third speed is completed, shifting to the forth speed is executed, however, at that time, the forth speed stage is established by releasing the first one-way clutch along with engaging of the second clutch.

Title: Color image sensor
Inventor: NAKAZAWA YOSHIO
IPC: H04N1/028
Filed: 1991-04-19
Abstract: PURPOSE:To quicken a read speed by providing an electrodeposition transparent conductive film in a space between an overlapped area of a photoelectric conversion means and a subscanning direction and providing a dummy pad sufficiently larger than a pad of an output signal line in the vicinity of the pad of the output signal line opposite to an electrodeposition electrode extract terminal. CONSTITUTION:It is essential to overlap an electrodeposition transparent conductive film 1 onto a photoelectric conversion means by 1-10mum and since no electrodeposition is attained for an isolated film 1, it is required to form the film 1 to be a consecutive pattern. However, the film 1 is the film 1 not overlapped onto a scanning circuit section and the output signal line and the isolated film 1 is connected in a space (subscanning direction) between the photoelectric conversion means. Moreover, a dummy pad with an area sufficiently larger than that of a pad 8b is provided to a metallic wire film 6 in the vicinity of the pad 8b of the output signal line. Thus, a pigment adhered to the pad 8b is almost eliminated, the parasitic static capacitance of the output signal line is reduced and the signal call speed is quickened.

Abstract: PURPOSE: To make it possible to apply this interface for data transfer to the check system and so on using a microcomputer advantageously, by transferring surely even a signal, which has a generation interval shorter than the processable interval, from the data supply part to the data processing part.  
     CONSTITUTION: In case that the generation interval time of the transfer request signal from data supply part 1 is shorter than the data processable interval time in data processing part 3, transfer of memory data DS in latch circuit 11 and transfer request signal FS 1  is stopped because AND circuits 41 and 51 close gates due to reset of FF 31. In stead of these memory data and transfer request signal, memory data DS given to latch circuit 12 and transfer request signal FS 1  given to AND circuit 52 are supplied to processing part 3. As a result, the signal of a generation interval shorter than the processable interval can be transferred surely to processing part 3 to apply this interface for data transfer to the check system and so on using a microcomputer advantageously.
