Title: Controlling device of positioning
Inventor: ITOU MASAAKI
IPC: H01L21/67
Filed: 1984-05-23
Abstract: PURPOSE:To smoothly perform acceleration in a short time, by appointing a low speed which gives a sufficiently weak impact at the time of start up and switching the speed to a desired high speed when a backlash becomes zero. CONSTITUTION:The linear motion of a driving system composed of a DC servomotor 11 and ball screw 12 is transmitted to a moving table 16 through a driving frame 14 and roller section 15 at the front end of a coupling rod 13. A backlash exists between the driving frame 14 and roller section 15 at the time of start up. A switch change-over circuit 18 composed of switches 19 and 20 and a monostable multivibrator is connected to the servomotor 11. Upon receiving a start-up signal, the circuit 18 closes the switch 19 for a fixed time ts and commands the motor 11 to reduce the speed to a low speed vs. After the backlash becomes zero thereafter, the circuit 18 opens the switch 19 and, at the same time, closes the switch 20 and appoints the maximum speed vt.

Title: Variable optical branching/coupling device
Inventor: KURATA NOBORU
IPC: G02B6/28
Filed: 1989-04-21
Abstract: PURPOSE:To optionally vary the branching ratio of light by melting and splicing one part of the outside circumferential surfaces of two or more optical fibers each other, mechanically drawing the spliced part in the optical axis direction of the optical fiber and changing the drawing length and the thickness of the melted and spliced part. CONSTITUTION:After one part of the outside circumferential surfaces of the optical fibers 11 and 12 consisting of a transparent elastic member are heated, melted and spliced each other, the central part of the melted and spliced part 13 is gradually thinned and drawn at the drawn melted and spliced part until the outside diameter thereof becomes the thickness of one optical fiber. At this time, when the gap between holding parts 14 and 15 is varied by rotating an adjusting screw 16, the melted and spliced part 13 elongates and contracts in the direction of the optical axis and the drawing length thereof is changed. Thus, the quantity of light leaking through one optical fiber 11 at the melted and spliced part 13 can be varied and the branching ratio of the light is optionally varied.

Title: Nonvolatile memory
Inventor: MURAKAMI SATOSHI
IPC: G11C29/04
Filed: 1994-05-18
Abstract: PURPOSE:To enable defective memory to be equivalent in its use to nondefective memory by allocating a defective memory block in the user memory region to the memory block in the spare memory region using a substitution table. CONSTITUTION:The substitution table 1 previously stores substitution address data or nonsubstitution address data in accordance with each memory block in the user memory region 4. It outputs substitution address data or nonsubstitution address data in accordance with input address data A8 to A15. When the substitution table 1 outputs nonsubstitution address data, a selector 2 outputs input address data A8 to A15, and when the substitution table 1 outputs substituion address data, the selector 2 outputs substitution address data. Consequently the nonvolatile memory 6 conducts data access to the memory block directed by the address data which the selector 2 outputs.

Title: Optical pickup device
Inventor: IWATA KAZUO
IPC: G11B7/09
Filed: 1987-04-27
Abstract: PURPOSE:To make a focus deviation signal hard to be outputted, to prevent an objective lens from being moved even at the time of crossing an information string and to prevent rasping sound from being generated, by arranging the position of a light source in a direction inclined by 40 deg.+ or -3 deg. against the direction orthogonal to the information string of an optical recording carrier. CONSTITUTION:The light source 3 is arranged in the direction inclined by 40 deg.+ or -3 deg. against the direction orthogonal to the information string of the optical recording carrier 1, and the parting line of a quarterly split optical detector 5 is inclined by 5 deg.+ or -3 deg. against the direction orthogonal to the information string of the optical recording carrier 1. And a part on which hatching is applied by a beam on the optical detector 5 shows that the part is an area where light strength is lowered at the time of beginning to cross the information string by a light spot on the optical recording carrier 1. In such a case, since the outputs of the areas (a) and (d) of the quarterly split optical detector 5 are decreased, the focus deviation signal FE scarcely changes and keeps a state almost equivalent to zero, even when the light spot on the optical recording carrier 1 crosses the information string. In such a way, it is possible to lower the output of the focus deviation signal by around 10dB, to make the movement of the objective lens 2 unnecessary at the time of crossing the information string, and to prevent the rasping sound from being generated.
