Title: Method for packing powder and device used therefor
Inventor: ARAI TAKASHI
IPC: B30B11/00
Filed: 1986-03-14
Abstract: PURPOSE:To uniformly pack powder into a rubber mold by packing the powder into the rubber mold under oscillation, sucking the air in the rubber mold and increasing the packing density of the powder in the rubber mold by the weight of the powder in the space in the upper part of the rubber mold. CONSTITUTION:The rubber mold 1 is set in an inside hole 2a of a supporting mold 2. The powder 3 in a hopper 4 is supplied by a feed pump 5 via a connecting pipe 6 into a feeder 9 and the rubber mold 1. Since an oscillator 8 exists in a supporting base 2, the powder 3 is increased in the packing density by the oscillation thereof and is packed without intrusion of the air by the suction of a vacuum pump 10. The feeder 9 is slid from the mold 2 and the rubber mold 1 is taken out when the packing of the powder into the rubber mold 1 is completed. The packing height of the powder in the feeder 9 is made about 1/3-1/2 the height of the rubber mold. The powder is uniformly packed at a high density into the rubber mold by the above-mentioned method and device, by which the cold hydrostatic molding having high strength and high accuracy is produced.

Title: Distribution type fuel injection pump
Inventor: KATO NOBUO
IPC: F02M41/14
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent any damage of a pump housing by enlarging a regulating range of a fuel press-feeding timing without increasing a size of an injection pump. SOLUTION: A timer housing 101 is made of aluminum and formed integrally with a pump housing 4. The timer housing 101 is formed into a box hole shape on a delay angle side of a timer piston 102 made of iron. A locking projection 112 formed on an inner cam ring 24 is locked to a bolt 111, thereby specifying a maximum lag position of the inner cam ring 24. Since the timer piston 102 does not abut against the inside wall of the timer housing 101 on the lag side in a state in which the locking projection 112 is locked to the bolt 111, it is possible to prevent the timer piston 102 from damaging the timer housing 101 even when the timer piston 102 is pressed toward the delay angle side together with the inner cam ring 24 by driving reaction force of a plunger 20.

Title: Copying method and copying apparatus
Inventor: YASUMORI AKIYOSHI
IPC: G03B27/00
Filed: 1979-05-04
Abstract: PURPOSE: To continually copy originals in a small size construction by transferring immediately to transfer paper an original image of reverse pattern memorized in a memory medium by a contact reflection system.  
     CONSTITUTION: Original 9 and rotary cylinder 4 comprising glass 1 or the like, transparent electroconductive layer 2 made of SnO 2  or the like, photoconductive layer 3, etc. relatively come into line contact in moving and rotating. Original 9 is irradiated with slit exposing apparatus. Since the reflected light is small in image areas and large in nonimage areas, an image reverse to the original in pattern due to change in electric resistance is memorized in layer 3. This memorized image before decay is immediately transferred to transfer paper 10 of electrothermal color recording paper or the like, or transferred to electrostatic recording paper as a static image and undergoes developing processing, thus permitting original image to be continually copied in a simple and small size construction.

IPC: H04B7/26
Filed: 1989-03-08
Abstract: PURPOSE:To extend the service life of a battery by providing a reception quality deciding means and a battery saving control means, using the reception quality deciding means so as to discriminate the reception quality from a reception signal at the reception of a group to which its own equipment belongs and controlling the reception of the group to which its own equipment belongs. CONSTITUTION:Reception electric field strength deciding means 41 monitors a synchronous word of a group to which its own equipment belongs as to whether or not the word is received accurately consecutively for, e.g. 10 frames, and it is decided that the reception electric field strength is sufficiently high when the synchronous word is accurately received. On the other hand, a battery saving control means 42 operates the reception circuit 10 at an internal of two frames when it is decided that the reception electric field strength is sufficiently high by the means 41. On the other hand, if the reception electric field strength which is sufficiently high is not obtained, the reception circuit 10 is operated for each frame. Thus, the power consumption when the selective call receiver is operated on the condition that the reception electric field strength is sufficiently high.
