Title: Developing device
Inventor: SHIMIZU TAMOTSU
IPC: G03G15/09
Filed: 1990-04-02
Abstract: PURPOSE:To prevent the increase of the driving torque of a developing roll and to prevent a white stripe by forming a developer puddle part near a pole on the upstream side of a same pole magnetization part so that it may not come in contact with a photosentive body. CONSTITUTION:By utilizing attraction force by the non magnetic pole area of the same pole magnetization part M1 and a different pole S2 on the upper- stream side than the part M1, the developer puddle part 38 is formed near the pole N3 on the upstream side of the part M1 and between the poles S2 and N3. Namely, since the poles N3 and N4 have the same polarity, the developer is temporarily restrained by the pole N3 and the restrained developer tries to return to the pole S2 along a magnetic flux, so that the developer puddle part 38 is formed. Since the puddle part 38 does not come in contact with the photosensitive body, stress between the photosensitive body and the developing roll is avoided. Even when the white stripe is caused in a bristle height regulating member 36, it is prevented by the puddle part 38.

Title: Gas laser device
Inventor: MATSUDA MASAYASU
IPC: H01S3/038
Filed: 1981-06-10
Abstract: PURPOSE:To allow the prevention of transfer from normal glow discharge to arc discharge, by connecting current adjustment elements respectively between a plularity of pin electrodes and power source in series. CONSTITUTION:Laser medium flows in a discharging part 20 as high speed air current with a bar electrode 21 and a plurality of pin electrodes 22 opposed thereto arranged via a required discharge clearance.

Title: Steering system for tractor
Inventor: KAWAGUCHI HIROMICHI
IPC: B62D7/14
Filed: 1989-04-07
Abstract: PURPOSE:To allow switch-over in steering in a simple manner by providing a switch-over shifter by freely switching over to either one of front wheel steering only by front wheels, front/rear wheel steering by both front and rear wheels, and rear wheel steering only by rear wheels. CONSTITUTION:A switch-over shifter 11 is operated with a switch-over lever actuated, and when a front and a rear switch-over gear 40 and 41 are moved to the rear end side, the gear 41 comes out of a gear 37 in a state that the gear 40 is meshed with a gear 36. This results in the interlocking configuration of front wheel steering F wherein a lock pin 43 is engaged with a lock hole 45, so that only a front switch-over shaft 35 is interlocked in steering by a steering handle 3. When a shifter 14 is moved to the center position, the gear 40 is meshed with the gear 36, the gear 41 being meshed with the gear 37, which resulting in the configuration of front/rear wheel steering W so that the front switch-over shaft 38 is interlocked with a rear switch-over shaft 39 in steering to the same direction. The gear 40 is disconnected from the gear 36 while a shifter 14 is positioned at the front end, a lock pin 42 concurrently being engaged with a lock hole 44, the gear 41 coming out of the gear 37, and is concurrently meshed with a gear 35. This results in the configuration of rear wheel steering so that only the shaft 39 is interlocked to the direction opposite to the steering direction by the handle 3 when compared with the case of front/rear wheel steering W.
