Title: Tightening device for meshing gear shaft system
Inventor: FUJITA KAZUHIKO
IPC: B23P19/06
Filed: 1986-10-20
Abstract: PURPOSE:To enable an assembly process to be shortened by providing a clutch mechanism which switches a nut turn stopping member from turn restrication to free turn when a detected torque reaches the preset value, based upon an output from a torque detector. CONSTITUTION:When a nut runner main body 5 is driven, the present rotary power is transmitted also to a counter-shaft 32 as well as transmitted to a main-shaft 31. Consequently, lock nuts 36, 38 are gradually tightened around the main-shaft 31 and the counter shaft 32 respectively. As the tightening work progresses until a tightening torque reaches 10kg.m or so, clutch mechanism 21 is switched to its cut off state, the turn stopping for the lock nut 38 is released and the lock nut 38 rotates in one body with the counter-shaft 32. Furthermore, tightening work for the lock nut 36 progresses and when tightening torque reaches 20kg.m or so, drive of the nut runner main body 5 is stopped.

Title: V belt transmitting device
Inventor: KAWAHARA HIDEAKI
IPC: F16G5/00
Filed: 1989-09-25
Abstract: PURPOSE:To attain the compactness of a transmitting device coping sufficiently even with maximum stress by overlapping a V belt with a retaining belt of high modulus, having its internal peripheral length slightly shorter than the peripheral length of said V belt, wound between two or more V pulleys and additionally applying initial tension only to said retaining belt of high modulus. CONSTITUTION:A V belt 2 of high modulus is wound linking between V pulleys 1A, 1B, and the belt 2 mounts to its upper overlapping a retaining belt 3 of high modulus with its internal peripheral length shortly longer than the peripheral length of the V belt 2. Next applying load torque, tension is applied in accordance with the load torque to a tensile side of the V belt 2. While the retaining belt 3 is rotated together with the V belt 2. Thus, the V belt 2 and the retaining belt 3 share a burden of power transmitting and initial tension holding functions, even when the load torque suddenly increases, the retaining belt 3 increases its tension effectively preventing a slip of the V belt 2, and it is able to be safely used even for a transmitting device such as generating maximum torque several times the steady torque in the time of starting. In this way, the device attains its compactness and lightness of weight.

Title: Image reader
Inventor: FUNADA MASAHIRO
IPC: H04N1/401
Filed: 1985-11-11
Abstract: PURPOSE:To attain image reading of high quality by compensating a reading signal and correcting dimming and shading at the reading of a reference reflecting plane such as a reference white board. CONSTITUTION:An image reading means 108 having an A/D converting means 106 reads out a reflected light beam from an original P irradiated by a light source 100. The reading means 108 reads out also a reflected light beam from the reference reflecting plane 110A and the quantity of light of the light source 100 is controlled by a light control means 120 so that the density of reflection coincides with a set value of a setting means 130. To read an image precisely, the reference voltage of the A/D converting means 106 is changed by a reference voltage setting means 130. A correcting means 130 obtains correcting data for the correction of shading to correct an image signal read out from the original P. Consequently, influence due to the change of the reflection density of the reference reflecting plane can be removed. Thereby, image reading of high quality can be attained.

Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To reduce dispersion of dust when a reclaimer is scraped, by successively receiving a cover unit in an upper step when a cover unit in the lowermost step is moved to be lifted. SOLUTION: In a part where a bucket 4a scrapes bulk from a pile, a bucket cover obstructs, so that it covers the upward from in the vicinity of the part with the bulk scraped. Since a height of the pile is changed in a part scraped by a traverse frame during traversing, the height of the pile is detected by a pile height detector 28, a detection value is fed as a signal to a cover position control device. The cover position control device calculates a position, where a cover unit 23a in the lowermost step must be placed, From a height of the part scraped by the bucket 4a, a command signal is fed to a rope rewinder 25, the cover unit 23a in the lowermost step is lifted. When the cover unit 23a in the lowermost step is lifted, it successively receives a cover unit 23 in an upper step.

Filed: 1994-10-17
Abstract: PURPOSE: To prevent the flying up of toner between a developing unit and a photoreceptor by applying the same voltage as that applied to a grid to developing rolls in a nondeveloping state. CONSTITUTION: The rotary drive of the photoreceptor 1 by a drum motor and electrification by a scorotron 2 are started and a control means 8 changes over all switches to the side of a switching terminal B, to apply grip power VG to the developing rolls 4a, 5a, 6a and 7a in the nondeveloping state from a grid power source 16. Then, the cleaning blade 13a and recovering roll 13b of a cleaning device 13 are separated from the surface of the photoreceptor 1. At the time of separating, toner stagnated on the edge of the blade 13a streakily remains on the surface of the photoreceptor 1, as residual toner. At this time, a potential difference is not made between the developing unit in the nondeveloping state and the photoreceptor 1 and an electric field is never formed as well. Therefore, the residual toner can not soars up toward the developing rolls 4a-7a.

Title: Acceleration sensor
Inventor: SUZUKI RITSUO
IPC: G01P15/12
Filed: 1991-09-30
Abstract: PURPOSE:To simplify structure, improve assembly performance and facilitate adjustment. CONSTITUTION:A ball 4 which moves along the inner surface when acceleration is applied is accommodated in a body 2 on which a recessed part 3 having the inner surface having an ascent slope towards the periphery from the center is formed. Further, a detecting lever 5 whose one edge is pivotally installed on the body and the intermediate part contacts the top part of the ball 4 is installed. A noncontact type sensor 6 such as magnetic resistance sensor and photosensor are arranged, positioned at the other edge of the detecting lever. When accelerating speed is applied, the ball moves along the inner surface of the recessed part, and the position of the ball changes upwardly. At this time, the detection lever in contact with the ball is pushed upward, and the displacement of the other edge of the detecting lever is sensed by the noncontact type sensor, and an electric signal is taken out.

Title: Correction of printing in typewriter
Inventor: TSUMURA TAKEO
IPC: B41J29/36
Filed: 1984-11-27
Abstract: PURPOSE:To clearly erase letters by eliminating transfer from a correcting tape to a printing paper by a method in which after the initial letter-erasing impact is made, the correcting tape is fed by a given amount. CONSTITUTION:A shifting base 4 is shifted upwards to shift a printing ribber or a correcting tape to type positions. A sprocket gear 1 is provided coaxially below a reel 5 for winding the correction tape. By the shifting action of the correcting tape during the letter-erasing period, a drive lever 2 for the gear 1 is operated toward the direction of arrows, and the reel 5 is turned to feed the correcting tape by a given length. At first, impact is only made without feeding the correcting tape, and then the correcting tape is fed by a given amount, followed by the second and third impacts. Since the amount of ink to be adhered to the correcting tape when the second and third letter-erasing impacts are made is small, the amount of transfer from the correcting tape to the printing paper is negligible.
