Title: Image forming device
Inventor: SAKAI YOSHIHIRO
IPC: G03G15/01
Filed: 1994-11-10
Abstract: PURPOSE: To enable sure alignment at a low cost by attaining the alignment of an intermediate transfer belt with the microstep drive of a stepping motor. CONSTITUTION: A BK toner image formed on a photoreceptor 9 is transferred to the intermediate transfer belt 19 driven at the same speed as the photoreceptor 9. The intermediate transfer belt 19 is stretched on a driving roller 21, a belt transfer bias roller 20 and a driven roller group and the belt 19 is drive-controlled by the stepping motor connected to the driving roller 21. As for the drive of the stepping motor, half step driving is adopted except the case used for a aligning control for aligning a toner image on the photoreceptor 9 with a fixed image forming position on the belt 19. On the other hand, in the aligning control, the driving step of the stepping motor is set smaller than a half step. In other words, the driving step of the stepping motor at this time is made the microstep drive.

Title: X-ray exposuring apparatus
Inventor: IIZUKA JUNICHI
IPC: G03F7/20
Filed: 1984-12-26
Abstract: PURPOSE:To reduce the probability that the synchrotron loses its function and to ensure the stable operation of the exposure portion by incorporating all movable pats interlocked to a reflecting mirror set in the drive mechanism which vibrates the mirror into the space occupying the mirror and sweeping the X-ray beam emitted from the synchrotron by means of vibration of the mirror. CONSTITUTION:The whole of a drive mechanism 12a which vibrates a reflecting mirror 3 is incorporated into a reflector room 4; a driving rod 9a and a vibrator 10a constitute a drive mechanism 12a. The driving body of the vibrator 10a is e.g. a linear motor or a piezo-electric device and the drive mechanism 12a is fabricated so that the movable pat including a driving rod 9 has no part to slide. Therefore all problems originating from the installation in vacuum, for example, the problems accompanying to lubrication can be avoided. Since the drive mechanism 12a has no part such as bellows, the probability that the synchrotron loses its function due to deterioration of vacuum in the reflector room 4 is markedly reduced.

Title: Gas flow rate measuring apparatus
Inventor: MATSUURA GAKUO
IPC: G01F1/28
Filed: 1985-12-11
Abstract: PURPOSE:To guarantee the accuracy in the measurement of flow rate and achieve compactization from a low flow rate state to a high flow rate state of a gas, by moving a moving member in the direction of flow according to the gas flow rate to convert the displacement of a shaft being displaced according to the movement into an electrical signal. CONSTITUTION:Air passage 2 comprising three housings 1a-1c composing a part of an intake tube of an engine is formed and a moving member 3 movable linearly along the direction of air flow is provided. While the movable member 3 is pushed to the fully closed direction opposite to the air flow direction with a coil spring 11, it moves on downstream due to an air flow rate based on the pressure difference between the up and downstreams generated from a specified air flow rate. With this, a shaft 3d is displaced downstream and the displacement is converted into an electrical signal with a potentiometer 18 to be fetched out through a pin 15. A pressure receiving area of the moving member is free from change in the flow rate. thus, a constant measuring accuracy can be obtained.

Title: Wire gage
Inventor: TAKAHASHI YUKIHIRO
IPC: G01B11/04
Filed: 1994-10-18
Abstract: PURPOSE: To enable highly accurate measurement with limited measuring errors by reducing variations in the distance between an electric wire and a camera. CONSTITUTION: Window parts of an electric wire 4 are pinched between a lower holder 5 and an upper holder 7 and are taken with a camera to measure dimensions of the respective window parts. The upper holder 7 is supported with the lower holder 5 and a slide rail 14 allowed to slide across the width of the electric wire 4 and having a recess part 13 formed thereon is arranged below a rotatable wheel 12 mounted on the lower holder 5. The slide rail 14 is moved across the width of the electric wire 4 with a drive body 15. The wheel 12 sinks into the recess part 13, causing the lower holder 5 to separate from the upper holder 7 and the pinching of the electric wire 4 with both the holders 5 and 7 is released.  When the rail 14 is moved in the opposite direction, the wheel 12 rides on the outside of the recess part 13 to let the lower holder 5 approach the upper holder 7 thereby allowing the pinching of the electric wire 4 with both the holders 5 and 7.

Abstract: PURPOSE:To suppress vibration reliably at all times by fixing a pair of electromagnets respectively to a weight and a body to be suppressed of vibration and attracting a plurality of mass members having specific mass to facing surfaces of respective electromagnets. CONSTITUTION:A weight 14 is arranged while being separated by predetermined distance from a body 2 subjected to vibration.

Title: Line pressure control device for automatic transmission
Inventor: KAWAMURA YASUTAKA
IPC: F16H61/00
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent worsening of fuel consumption due to the increase of a line pressure to an excessive value during feedback by a factor of safety to compensate for lowering due to unevenness in line pressure characteristics. SOLUTION: At 31, a target line pressure PREQ* is determined by multiplying a necessary line pressure PREQ, corresponding to an operation state, by a factor safety S1. At 32, a deviation ΔPerr between the PREQ and a real line pressure PL is calculated and at 33, based on the deviation ΔPerr, a known PI computation is effected to determine a PI control amount ΔPPI according to the deviation ΔPerr. At 34, when a feedback control permission signal is present, it reaches a solid line position and the ΔPPI is set to a feedback control amount ΔPFB. When a feedback control permission (ON) signal is not present, it reaches a broken line position and 0 is set at ΔPFB. At 35, ΔPFB is added to the PREQ* to determine a command line pressure PL*. At 36, a line pressure solenoid duty D at which PL* is achieved is decided.  Since 31 is present in a position shown in Fig. during feedback control, a line pressure follows and is controlled not to PREQ* but PREQ and it is prevented from occurring that a line pressure is increased to an excessive value by an amount equivalent to a factor of safety.
