Inventor: KATSURAYAMA KUNIHIRO
IPC: B65G65/40
Filed: 1978-11-30
Abstract: PURPOSE: To facilitate the inner cleaning and to stabilize the quality of powder material, by locating upper and lower shutters on the outer cicumference of exhausting casing made of soft material.  
     CONSTITUTION: Exhausting casings 1 made of soft material are located in up and down direction, while upper shutter 2 and lower shutter 3 equipped with a pair of holding member 8 and cylinder 5 are located on the outer circumference of exhausting casing 1. When operating the cylinder 5 to close lower shutter 3 and to open upper shutter 2, powder material is stored between lower shutter 3 and upper shutter 2 of exhausting casing 1, while when closing upper shutter 2 and opening lower shutter 3 powder material is exhausted. Since powder material doesn't contact with driving machanism, the quality is stabilized while since there is no inner drive mechanism inner cleaning is facilitated.

Title: Image module mounting device
Inventor: UIRIAMU JIEI NOWAKU
IPC: G03G15/00
Filed: 1993-06-21
Abstract: PURPOSE: To enhance dynamic performance without creating an overconstraint condition by allowing a movable means to respond to frequency different in motion between a module and a frame to variably flexibly minimize the misregistration or strain of an image. CONSTITUTION: Fixed mounting points 170, 172, 174 establish the important position data of an image module 30 to hold the same. A stable mounting device 180 is positioned at the fourth corner of the image module 30. This flexible mount 180 is planned so as to achieve the function of a fixed support device with respect to high frequency vibration or other high frequency motion. However, the mount 180 is distorted, that is, floated with respect to low frequency motion such as the strain of a frame due to the movement of a machine or the strain due to thermal change so that the image module 30 holds a plane. Therefore, the misregistration of a raster line 46 in the processing method shown by an arrow A generated by the distortion or strain of the image module 30 can be minimized.

Title: Driving device for recording body or the like
Inventor: KAMEYAMA TORU
IPC: F16F15/12
Filed: 1985-07-08
Abstract: PURPOSE:To realize a structure in which variation in other loads is not transmitted to a photosensitive body, etc., at low cost by providing a buffer member where recording paper or a recording paper holder receives driving force from a power transmission means. CONSTITUTION:If the speed of a chain 3 increases momentarily owing to variation in loads other than a photosensitive body 9, rotary torque transmitted from a driving gear 6 to a gear member 20 increases momentarily and torque transmitted from walls 20c and 20d of a groove to leaf spring members 22 and 23 also increases momentarily. The increment in the torque, however, depends upon the inertia of the photosensitive body 9, so it is not transmitted to a disk member 21 and succeeding members only by increasing the inflection of the leaf spring members 22 and 23 momentarily. Similarly, if the chain 3 decreases in speed momentarily, the rotary torque decreases momentarily, but this is not transmitted to the disk member 21 and succeeding members because of the inertia of the photosensitive body 9. Thus, the structure in which the variation in loads other than the recording body is not transmitted to the recording body, etc., is realized compactly at low cost.

Inventor: SHIBUYA TADASHI
IPC: H02M1/06
Filed: 1985-07-08
Abstract: PURPOSE:To prevent an abnormal current from generating by providing a time difference in the gate signal interruption of a thyristor switch which contains a commutation capacitor. CONSTITUTION:A forcible commutation circuit has main thyristors THP, THN of a thyristor switch 5U connected in anti-parallel, and a controller 7 which applies a gate pulse to an auxiliary thyristor THU, and has a commutation reactor LU, a commutation capacitor CU, an auxiliary thyristor THU, and a flywheel diode DU. After the controller 7 interrupts the gate signal of one main thyristor THN reverse to the voltage polarity of the capacitor CU, it fires the thyristor THU. This firing generates a vibration current from the reactor LU to turn OFF the other thyristor THP with the inversion energy of the capacitor CU, and to return the voltage polarity of the capacitor CU to the initial state to forcibly commutate.

CONSTITUTION:A retaining mold 1 has a box body 2 at the bottom part thereof and also has a tapered projecting surface at the upper part thereof and drain holes 6 are provided to the bottom part of the box body 1. Decorative aggregate is thrown in the retaining mold 1 and sealing aggregate is subsequently thrown therein to apply vibration to said mold 1. It is sufficient to once apply vibration after the aggregates are thrown in the mold 1. Subsequently, water or water containing a water-soluble adhesive is sprayed. Bonding often becomes inferior when the sealing aggregate is wet to a necessary degree of more. If the drain holes are provided to the bottom part of a face plate, excessive water is discharged from the drain holes. Thereafter, vibration is applied if necessary and the face plate is subsequently coated with mortar if necessary and, after concrete is cast to be compacted under vibration, the molded one is demolded and aged to obtain a surface decorative concrete block. By this method, the amounts of all of the decorative aggregate, the sealing aggregate and mortar, respectively can be freely adjusted and a projecting degree can be sufficiently adjusted.
