Inventor: MARUYAMA TAKUYA
IPC: B62D5/06
Filed: 1983-06-17
Abstract: PURPOSE:To stabilize steering properties by providing a flow control valve which is provided on an oil tank and a steering shaft and allowing the steering force to become heavier when running on a low friction road. CONSTITUTION:A flow control valve 35 is provided between the passages of both of an oil feeding side oil passage 29 from an oil pump and a drain side oil passage 30 to an oil tank.

Title: Image forming device
Inventor: ADACHI KOICHI
IPC: G03G15/01
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent toner-image disturbance and to improve efficiency in transferring an image from the image carrier to transfer paper. SOLUTION: The width W2 of the contact of a carrying belt 3 with a transfer unit 12 in a transfer-paper carrying direction is made equal to or greater than the width W1 of the contact of the carrying belt 3 with the image carrier 5 in the transfer-paper carrying direction. Therefore, even in the case a transfer bias which is applied to the transfer unit 12 is decreased, a toner image on the image carrier 5 can be transferred to the transfer paper satisfactorily. This eliminates or reduces the influence of a transfer electric field of the transfer unit 12 which is exerted on the transfer paper right before the transfer paper comes into contact with the image carrier 5.  Thus, because, right before the contact of the transfer paper with the image carrier 5, discharge in a minute space between them is restricted, toner-image disturbance is prevented and the efficiency in transferring the image from the image carrier 5 to the transfer paper is improved.

Title: Fiber reinforced thermoplastic resin pipe
Inventor: SATO HAJIME
IPC: B29C53/82
Filed: 1991-05-14
Abstract: PURPOSE:To prevent the generation of electrolcorrosion in a metal joint when pipes are connected by the metal joint by forming an electric insulating layer composed of a thermoplastic resin to the inner surface and/or outer surface of the pipe. CONSTITUTION:A conductive prepreg containing a thermoplastic resin as a Matrix and an electric insulating prepreg composed of a thermoplastic resin are interposed between a thermally expansible core 3 and the cylindrical outer mold 1 arranged outside the core 3. The core 3 is thermally expanded to obtain a fiber reinforced thermoplastic resin pipe. As mentioned above, since an electric insulating layer composed of a thermoplastic resin is formed to the inner surface and/or outer surface of the pipe, a metal joint becomes the state coming into contact with the electric insulating layer when the metal joint is arranged to the end parts of the pipes to connect the pipes and, therefore, the metal joint can be prevented from being deteriorated by the generation of electrocorrosion.

Abstract: PURPOSE:To control the starting characteristic optimally by providing a microcomputer, furnishing a waveform shaping circuit which emits a rectangular wave signal obtained from the output signal given by a rotational angle sensor which shall undergo waveform trimming, and by installing a backup circuit. CONSTITUTION:A waveform shaping circuit 10 compares the output signal from a rotational angle sensor 1 with s specified signal judging level using a comparator CMP and generates a rectangular wave signal. When the output of this comparator CMP is inverted, a differential output is generated by a differentiating circuit consisting of a diode D3, capacitor C3, and resistance R9 and supplied to the signal judgement level of the CMP to give it a hysteresis. The rectangular wave output phase of CMP is varied according to the warmed-up condition of an internal combustion engine concerned by changing the size of the differentiation voltage in the differentiating circuit in accordance with the output of a water temp. sensor 2a (warmed-up condition sensor). When microcomputer 50 does not emit normal ignition signal, for ex. in case it is in failure or under starting motion, a backup circuit 40 emits a signal from the circuit 10 as an ignition signal.
