Title: Manufacture of semiconductor device
Inventor: KIKUCHI KAZUYA
IPC: H01L21/76
Filed: 1985-02-27
Abstract: PURPOSE:To avoid the generation of defects at the time of ion implantation, and to enable the uniform formation of an impurity diffused layer in a fine vertical isolation groove, by a method wherein a P-type diffused layer is formed by ion implantation of boron into the semiconductor film, which film is then changed into an N-type diffused layer by ion implantation of arsenic; then, a P-type diffused layer is formed by removing the N-type diffused layer. CONSTITUTION:Isolation grooves 12 are formed by etching a semiconductor substrate 10. Next, a semiconductor film 13 is formed. After boron ion beams 14 are implanted into the semiconductor film 13, a P-type impurity diffused layer 15 is formed in the surface of the isolation groove 12 by heat treatment. Then, the boron concentration in the film 13 becomes constant, and the film 13 diffuses in the form of the solid-phase diffusion source, resulting in the formation of the P-type impurity diffused layer 15. After arsenic ion beams 16 are implanted into the film 13, it is formed into an N-type semiconductor film 13A by heat treatment. When the semiconductor film 13A is selectively etched, a P-type impurity diffused layer 15 serving as the channel stopper layer is uniformly formed to the bottom and side surfaces of the isolation groove 12.

Title: Gear noise preventing device for preserving gear
Inventor: KUDO SATOSHI
IPC: F16H3/40
Filed: 1986-02-25
Abstract: PURPOSE:To obtain a compact and light-weight gear noise preventing device having a small number of components by providing a member of check means in form of a recess formed in an intermediate shaft between input and output gears and providing the other member of the check means in form of a pin or projection. CONSTITUTION:When an intermediate gear 17 is shifted to the right, the intermediate gear 17 is brought in engagement with an input shaft 4 to be rotated, but with no load, it is freely rotated, causing no gear noise. At this time, a sleeve 11 is pressed by a disc spring 22 to be moved to the right along with the gear 17 and a frame 18. When a pin 14 reaches a inclined check surface 8, movement of the sleeve 11 is restricted by the pin 14 and the inclined check surface 8, so that the disc spring 22 is compressed to bring friction surfaces 13, 20 of a brake 21 in contact with each other and thereby to apply braking force to the frame 18. The brake 21 generates the braking force due to tight contact between the friction surfaces 13, 20 caused by a component of the torque in the direction of the inclined check surface 8. Then, the intermediate gear 17 comes in smooth engagement with an output gear 5 synchronous therewith to complete shifting operation.

Title: Image forming device
Inventor: HONDA TAKAO
IPC: G03G15/16
Filed: 1989-02-20
Abstract: PURPOSE:To enable invariably stable and excellent transfer without causing, specially, the back contamination of a transfer material by arranging a toner receiving member nearby a transfer position and a conveyance guide and providing a means which varies the potential of the toner receiving member. CONSTITUTION:The toner receiving member 7 which is connected to a variable voltage power source 20 is arranged nearby the tip opening part of upper and lower guide plates 8 and 9. In the process wherein scattered toner sticks on the toner receiving member 7, a current to the toner receiving member 7 is nearby a transfer charger, earthed, and is lower in potential than the guide plates 8 and 9, so the current is larger than a current which flows to the guide plates. Suspended and scattered toner particles move as shown by an arrow Wa before reaching the guide plates by being carried by corona wind and almost all of them are collected by the toner receiving member 7. Consequently, the sticking of toner to the guide plates 8 and 9 can be suppressed to as a small quantity as possible to prevent the contamination of a conveyance guide which conveys a transfer material, an irregularity in electrostatic charging due to the contamination of the transfer charger, a defect in transfer, etc.

Filed: 1980-03-26
Abstract: PURPOSE:To reduce an occupied area of a bus line wiring by a method wherein a plurality of the circuits generating timing signals are divided and arranged near specific peripheral circuits in which the outputs thereof are used as the inputs. CONSTITUTION:The timing signals generating circuits 1b operate the divided timing signals generating circuits 2b and 2c which have five output signal lines. Since the load capacity Cb is increased by a wiring extension, a driving capability of the circuit 1b is required to be increased. However, the increase of a pattern area has not influence on a chip size very quite. The driving capacities of the circuits 2b, 2c become advantageous as much as the length of the bus line shortened. The increased part of the pattern area due to the division by two can be ignored as compared with the reduced part of the bus line area.
