Title: Automatic copy original feeder
Inventor: SASAKI OSAMU
IPC: B65H5/02
Filed: 1980-10-24
Abstract: PURPOSE:To prevent a copy original end from lifting at an outlet gate in order to arrange the end exactly, by providing a flexible roller to increase a contact area between a single belt and an original-placing glass. CONSTITUTION:A copy original 32 set with an original-setting member 9 is fed onto an original-placing glass 1 by fixing a setting position with a stopper 14, withdrawing this stopper 14, and bringing a press roller 17 into contact with a turn roller 10. The original 32 is conveyed on the glass 1 with a single belt 24, and at that time a positioning claw 29 is lifted and the end of the original 32 comes into contact with  the claw 29 to complete its positioning. A contact area between the belt 24 and the  glass 1 is increased and uniformized by causing a flexible press roller 31 to come  into face contact with the glass 1 by the medium of the belt 24, thus permitting lift  of the end of the original 32 to be suppressed when the claw 29 is lifted, and correction of skew of the original 32 to be ensured.

IPC: B31B50/96
Filed: 1991-05-24
Abstract: PURPOSE:To obtain a stably aligned pile by obtaining a speed command which is the ratio of a corrugated cardboard sheet supplying quantity to a cutting length multiplied by the feeding speed of a conveyor, making correction by means of a loading level of the sheets, and optimizing the fall between the conveyor and a table. CONSTITUTION:The supplying quantity of corrugated cardboard sheets 10 to be fed into a stacker is obtained by making a direct measurement of the singling thickness by means of a distance sensor LPH. The command value of the lowering speed at a table 20 is obtained by multiplying the ratio of the obtained sheets supplying quantity to the sheets cutting length by the conveyor feeding speed VC. This command value allows the piling level of the corrugated cardboard sheets 10 discharged onto the table 20 to be detected by level sensors PH1, PH2 and the command value of the lowering speed to be corrected when the lowering speed of the table 20 is controlled. The output from the level sensors PH1, PH2 changes the command value of the lowering speed of the table 20 in a stepless manner, securing the stable fall.

Then, acceleration sensors 1A and 1B are pushed to the surface of the member 3. When the turntable 5 is rotated, the surface of the turntable is scanned with the sensors 1A and 1B. When there is a step at a joint 4, the acceleration of the member 3 in the direction of the radius is largely changed when the sensors pass the step. The acceleration signals are outputted from the sensors 1A and 1B. Optical sensors 7A and 7B at the attaching part are attached at the height of attaching parts 31A and 31B. When the attaching parts 31A and 31B are detected, the detected signals are outputted.

Title: Manufacture of integrated circuit substrate with excellent thermal conductivity
Inventor: MOCHIZUKI MASATAKA
IPC: H01L23/12
Filed: 1985-07-08
Abstract: PURPOSE:To facilitate the injection of an objective fluid even if the injection port is extremely narrow with the width of around several scores of mum having no specific effect on the viscosity of objective fluid and the capillary pressure at the injection port by a method wherein condensible fluid as working fluid is injected utilizing the vacuum pressure applied by repeated heating and cooling down processes. CONSTITUTION:An opening in a fine groove 2 is covered with a cover 4 and then whole body is heated up to specified temperature to be cooled down by condensible fluid as working fluid filling the fine groove 2. Said processes are repeated several times. The internal pressure is raised by heating process to exhaust a bit of non-condensible gas while the internal pressure inside the fine groove 2 is lowered by cooling down in the condensible fluid to absorb the condensible fluid into the fine groove 2. Besides in case of the second time heating process or later, the condensible fluid is evaporated in the fine groove 2 to exhaust the non-condensible gas more actively. Resultantly, the condensible fluid absorbed into the fine groove 2 can be gradually increased by repeating the heating and cooling down processes.

Abstract: PURPOSE:To allow a printed board to which an external force is directly applied when it is used to be secured by fitting a projection arranged on the tip of a pawl of a fixing member into a hole arranged on a second printed board so that the pawl will not be disengaged from the end portion of a first printed board, without increasing the man-hour. CONSTITUTION:A printed board 1 has its end held by a pawl 4 that projects from a fixing member 7 to be thereby fixed to the fixing member 7. A printed board 2 arranged on the back of the printed board 1 is fixed to the fixing member 7 by another pawl and the like. The tip of the pawl 4 is integrally formed with a projection 5 that is inserted into an insertion hole 3 of the printed board 2. As a pushbutton 6 is deeply pressed, the pawl 4 receives a force in the direction where the pawl 4 is disengaged from the printed board 1. However, since the projection 5 of the pawl 4 is inserted into the insertion hole 3 of the printed board 2, the disengagement of the pawl 4 is prevented. Accordingly, the printed board 1 to which an external force is directly applied can be fixed to the fixing member 7 without screws, whereby the man-hour can be reduced.

IPC: G03G5/02
Filed: 1980-10-29
Abstract: PURPOSE:To further improve the temp. dependency of an electrostatic recording body and the quality of an image by regulating the average particle size of photoconductive zinc oxide as the principal component of the low resistance layer of the body to <=0.3mum. CONSTITUTION:The low resistance layers 2, 2' of an electrostatic recording body are formed on one side or both sides of a support with photoconductive zinc oxide and an insulating resin as principal components. At this time, the average particle size of the zinc oxide is regulated to <=0.3mum. The recording body is irradiated with ultraviolet rays or white light and used in a low resistance state. When the zinc oxide has <=0.3mum average particle size, a smaller quantity of light for exposure is required. In case of 0.35-0.6mum zinc oxide used in an electrophotographic receptor, a considerable quantity of light or exposure is used to sufficiently lower the resistance value.
