Title: Steering angle detection mechanism
Inventor: SHIMIZU YASUO
IPC: G01D5/347
Filed: 1985-01-30
Abstract: PURPOSE:To facilitate the detection of a steering angle with the miniaturization of the mechanism, by providing light transmitting sections on a steering shaft at an equal interval along the circumference thereof and two units of photoelec tric elements shifted in the phase from each other to detect the transmission light therethrough. CONSTITUTION:Projections 21 are formed on the circumference of the second shaft and serves as light intercepting section to intercept light with the turning of a steering wheel while the clearance thereof transmits light as light transmit ting section 21a. Two units of photoelectric elements 22A and 22B each compris ing light emitting element and a light receiving element are arranged on a steering column 1 sandwitching the light transmitting section 21a, where the light emitting element comprises photodiodes 23 and 25 and the light receiving element does phototransistors 24 and 26. Then, as the elements 22A and 22B are so arranged to be different in the phase from each other, with the turning of the steering wheel, lights of the photodiodes 23 and 25 passing the light transmission section 21a are received with phototransistors 24 and 26 and pulse- like electrical signals shifted in the phase are outputted. This enables the detec tion of the steering angle on the steering shaft.

Title: Automatic ticket examining machine
Inventor: NAKAGAWA HIDEKI
IPC: G07B15/00
Filed: 1995-01-06
Abstract: PURPOSE: To allow user to exit only when an entrance place is present and a ride is correct by judging whether or not information specifying an entry is recorded on one of read media and whether or not a ride from an entrance place to an exiting place is correct on the basis of plural media. CONSTITUTION: When a user inserts a ticket for a ride from a station A to a station B into an A-station automatic ticket examining machine, a CPU 10 drives an encoder 14 to magnetically record entrance data 1 on the train ticket. If only a commutation ticket is inserted because of a fear of the detection of an illegal act although two media (train ticket and commutation ticket) should originally be inserted, a NO decision is made since entry data 1 as entry specification information is not recorded, so that abnormality is indicated. When the user inserts the train ticket and a commutation ticket for rides from a station C to a station D into an automatic ticket examining machine of the station D when exiting, a CPU 20 detects the entry data 1 of the inserted train ticket and judges the ride sections of the two media.  In this case, the CPU 20 decides that the ride sections of the both are not continuous, and then decides that the ride between the stations B and C is what is call that user goes by train paying only for the first and last sections of the ride, thereby indicating abnormality.

Filed: 1991-02-07
Abstract: PURPOSE:To prevent the occurrence of toner image turbulance without using an AC corona discharger when a body to be developed in which a toner image is formed is separated from an electrostatic latent image carrier. CONSTITUTION:A record supporting body 114 is made to contact a body to be developed 102 on the downstream side from a developing process and also on the upstream side from a part where the said body to be developed 102 is separated from an electrostatic latent image carrier 101 in the feed direction of the body to be developed 102.

Abstract: PURPOSE:To improve assembly performance and to reduce the number of parts by disposing a bearing surface both on a retainer and an outer race, and providing an elastic body for pressing the bearing surface of the retainer and pressing roller to the wall of a cam chamber opposite to the driving direction. CONSTITUTION:In the initial condition, a retainer 2 is pressed by a spring 4, so that a roller 3 fitted to a projection 2a is pressed to the narrower side of the cam chamber 1b, that is, in the opposite direction to the driving direction to couple a pinion 5 to the retainer. When a starter is started, an armature shaft and a torsion spline 1c are engaged with each other, so that the pinion 5 is advanced to be connected to a link gear. The rotation of the armature shaft is transmitted from the spline 1c to an outer race 1 and further to the retainer 2 coupled to the pinion 5 by the roller 3, so that the pinion 5 rotates the ring gear to start an engine. In this arrangement, the number of elastic bodies for pressing the roller is smaller than the number of the rollers, and before assembling springs for always pressing the rollers, in the condition where the inside diameter is large, parts may be assembled in the inside diameter, which can reduce the number of parts and improve the assembly performance.

Also, the gas 12 jetted to the lower face of the lens 18 is brought to an adiabatic expansion and a gas curtain is formed on the lower face of the lens 18. In this way, simultaneously with cooling, it is prevented that a foreign matter adheres to the lower face of the lens 18.
