Title: Visual-sensitive device
Inventor: NONAKA KENICHI
IPC: G01C3/06
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a satisfactory photographed image even in airsol by arranging a light source and a camera as that the expanded angle of illuminating light emitted from the light source and the field angle of one picture element of the camera are made smaller than the angle formed by the optical axis of illuminating light and the optical axis of reflected light from an illuminated area to the camera. SOLUTION: A light source 1 for illumination and a video camera 2 are arranged in the vertical direction of the front part of a vehicle 7 with the relation (θ1 , θ2 <α) so that the expanded angle θ1 of illuminating light LL at the light source 1 and the field angle θ2 of one picture element of the camera 2 are made smaller than an angle αformed by the optical axis of the illuminating light LL, with which a front road surface 8 is irradiated, and the optical axis of reflected light RL from the road surface 8.  Thus, even when any airsol such as mist, smoke or powder dust exists in the illuminated area, the reflected light RL having a high S/N, for which the quantity of light of noise toward the light receiving part of the camera 2 at the time of scattering the illuminating light LL because of that airsol is suppressed to a minimum, can be received by the camera 2 and the image of the road surface 8 in front of the vehicle can be effectively picked up.

Title: Coated optical fiber
Inventor: NONAKA TAKESHI
IPC: C03C25/24
Filed: 1988-08-31
Abstract: PURPOSE:To increase a fiber drawing speed and to improve productivity by using a polymn. initiator which cleaves a inter-heteroatom single bond by irradiating the polymn. with energy rays. CONSTITUTION:The coated optical fiber 3 is constituted of an optical fiber 1 and a coating layer 2 consisting of an energy ray curing type resin on the outer periphery thereof. The initiator which cleaves the inter-heteroatom single bond by irradiating the polymn. with energy rays is used as the polymn. initiator of the energy ray curing type resin. For example, benzoyldiphenyl phosphine oxide, etc., are used as the polymn. initiator which cleaves the single bond of a carbon atom and a phosphorus atom. Since the energy required for the cleavage is small, these polymn. initiators have the high cleavage effect when the same energy as heretofore is applied to thereto. The curing rate is then increased and the productivity is improved by the high-speed fiber drawing.

Title: Steering gear for vehicle having both main driver's seat and auxiliary driver's seat
Inventor: SAITO MASAO
IPC: B62D5/07
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To facilitate steering at an auxiliary driver's seat and secure safe turning motion of a vehicle, by inserting a spacer member between a stopper member, provided on a knuckle, and a stopper receiving part. SOLUTION: One end of a bracket 154 is fastened to a base part 52b of a knuckle 52 and an air cylinder device 156 is attached to the other end thereof. A maximum steering angle variable means for leftward steering is made up by mounting a spacer member 160 on a free end part of a piston rod 158 thereof. Further, a maximum steering angle variable means for rightward steering, constituted of an air cylinder device 156 and a spacer member 160, is also disposed on the right-hand front side.  When the knuckle 52 makes turning motion around a king pin 146, the spacer member 160 makes hitting contact with the stopper receiving part 150, and, in other words, they are formed such that the spacer member 160 is inserted between the stopper member 148 and the stopper receiving part, and therefore the knuckle 52, hence a maximum steering angle of front wheels, is established so as to be smaller by the thickness of the spacer member. By this, the steering angle becomes sufficiently smaller than usual and therefore safety is brought about.

Title: Power mos drive circuit
Inventor: UEJIMA AKIYOSHI
IPC: H02M1/08
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To surely change over a drive circuit before a surge voltage is generated by installing a voltage-change detection means which detects the change rate of the gate voltage of a power MOS transistor. SOLUTION: When a power MOS transistor 5 is turned off, the change rate of the gate voltage Vg of the power MOS transistor 5 is detected by a dv/dt detection circuit 6 as a voltage change rate detection means. Then, on the basis of its detection result, a gate driving power changeover operation is performed by a changeover means when the power MOS transistor 5 is turned off. By this constitution, when the power MOS transistor 5 is turned off, an electric charge which is stored in its gate is pulled out, and the gate voltage is lowered once. After that, since the electric charge due to a miller capacitance is pulled out, a period in which the voltage is not changed exists. The period in which the voltage is not changed is detected by the voltage change rate detection means.  On the basis of its detection result, the gate voltage is lowered gently, and a gate driving power is reduced by a prescribed amount. As a result, it is possible to suppress the generation of a surge voltage when the power MOS transistor is turned off.

Abstract: PURPOSE:To correctly correct distortion of a signal due to a secular change by devising the equipment such that other transmission original loaded before a current transmission original does not exist in front of a photoreceiving face and a background level is revised automatically to the newest value prior to the start of communication. CONSTITUTION:An output from a sensor 6 is inputted to a binarizing circuit 4 and distortion correction is applied at a background level stored in advance in a memory 5 and converted into a binarized signal. The memory 5 is formed as a RAM and the write is controlled by a memory write control circuit 2' built in a read control circuit 2 and the write is required to be implemented when no transmission original 12 exists on the photoreceiving face 11. The timing when no transmission original 12 exists on the photoreceiving face 11 is easily recognized by using a control section 1 to manage a sensing output of original sensors 9, 10, a drive command to a paper feed motor 8 and a lighting command to a light source 7 or the like. Then when the storage content of the background level is revised at each communication till the performance (picture quality) is not deteriorated, excellent picture quality is kept.

Filed: 1988-08-30
Abstract: PURPOSE:To form an opening hole smaller than a 1st resist film and to form a minute resist pattern efficiently by laminating and adhering the 1st resist film and a 2nd resist film different in composition on the flank of the opening hole of the 1st resist film, and removing the nonreacting layer of the 2nd resist film. CONSTITUTION:The 1st resist film 11 is formed on a semiconductor substrate 101 and irradiated with an electron beam 13 as shown by an arrow according to a specific pattern. Then the 1st resist film 11 is developed by a liquid developer to form the opening hole 11a. Then a resist film 12 is formed by coating and a heat treatment is carried out to form a reacting layer 14 of both resist films which is not peeled by the peeling processing of the 2nd resist film 12 at the border between the 1st resist film 11 and 2nd resist film 12. Then, ultraviolet rays are projected so as to peel the 2nd resist film 12 which does not react and then the substrate is dipped in the liquid developer to form the resist pattern. Consequently, the opening hole of the 1st resist film can be set wider than finally needed opening hole size and the fine pattern is easily formed with good reproducibility.

Title: Control mode switching device
Inventor: UJINO KAZUO
IPC: G05B7/02
Filed: 1989-08-24
Abstract: PURPOSE:To attain the safety control even right after the switch of the control modes by tracking the value set right after the switch to the process value set right before the switch. CONSTITUTION:A control mode switch 1 performs the switch between a semi- automatic control mode (mode A) and a full-automatic control mode (mode C). The value SV set right after the switch is tracked to the process value PV0 set right before the switch when the mode A is switched to the mode C. As a result, the coincidence is obtained between the set value SV and the process value PV and at the same time the change rate of the value SV is controlled to the value less than an allowable level. Thus the stable control is attained even after the switch of the control modes.
