Title: Beam shutter for optical pickup
Inventor: MATSUI TSUTOMU
IPC: G11B7/12
Filed: 1982-12-13
Abstract: PURPOSE:To reduce the size of a beam shutter by bringing a part of a semicylindrical shutter rod into contact with the projection surface of a semiconductor laser, and sliding the shutter rod at right angles to an optical axis through the operation of a shutter operating plate. CONSTITUTION:When a player is not in operation, the beam shutter operating plate 16 is not operated by the one end part 10G of a shutter rod 10 and the shutter rod 10 is pushed toward the plate 16 by a coil spring 15; and the upper flank 10D is pressed against the upper flank 11B of the semiconductor laser 11 and a passage part 10C cuts off a light beam. When the player is in operation, the plate 16 operates to move to the side of a housing 12, so the passage part 10C is positioned where the light beam is passed. When the plate 16 is returned to its original position in order to close the beam shutter, the rod 10 moves to the side of the plate 16, closing the shutter. The light beam diameter at the position of part 10A of the rod is small in this constitution and the operation stroke of the rod 10 is reduced to reduce space loss.

Title: Solenoid valve device
Inventor: IDA MASAHIRO
IPC: F16K31/06
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce the oil attack noise caused by rapid hydraulic pressure fluctuation by acting a clearance between an outer peripheral part of a movable core moved toward a fixed core by current-carrying in a coil and an inner circumferential part of a sleeve as a resistance of an operating fluid led in the sleeve, and suppress movement of the moving core. SOLUTION: When current-carrying in a coil 3 is carried out, a magnetic passage is formed bypassing a sleeve 2, a yoke 4, a fixed core 5 and a moving core 6, and the moving core 6 is sucked and moved downward against a spring 9. When a valve element 6b abuts on a valve seat 8a, communication of first and second ports 2b, 8b is broken. In the case where the moving core 6 is slid, an operating fluid formed on one end surface 6a side of the moving core 6 flows toward the other end surface 6b. In this time, an orifice action is generated between an outer peripheral part of the moving core 6 and an inner circumferential part of the sleeve 2 for connecting each terminal part of first and second grooves 6c, 6d, so as to suppress fluid motion of the operating fluid, and suppress rapid movement of the moving core 6.

Abstract: PURPOSE:To prevent a hurt of fingers when touching a side molding with a finger which cannot touch a burr portion, by making the back wall part broader than the front wall part, both of which form a groove of the side molding of a window glass. CONSTITUTION:The front wall part 12a and the back wall part 12b of a side molding 12 form a groove 6, and the back wall part 12b is formed broader than the front wall part 12a.

Title: Slide mechanism for optical head
Inventor: SUDA KAZUYUKI
IPC: G11B21/02
Filed: 1985-10-02
Abstract: PURPOSE:To omit the supply of lubricant for a long period and to facilitate the easy maintenance for a slide mechanism for optical head, by forming a space area to a bearing member which supports freely slidably a shaft extending in parallel with a recording medium to make the shaft pass through and storing the grease or lubricant into said space area to soak the shaft partly. CONSTITUTION:A sink part is formed with a substrate 22 coupled to an optical head main body 20, a pair of bearing plates 24 and 25, a side plate 27 and a bottom plate 28. Then the grease 29 is stored into the sink part so that the lower part of a shaft 23 is soaked into the grease 29. Thus the shaft 23 is effectively lubricated and also the extra grease is sent back to the sink. This prevents the mixture of the grease 29 into a machine even at a high temperature. As a result,the supply of grease is not needed for a long period and the easy maintenance is secured.

Title: Stepping motor driver
Inventor: ARAGAKI TAKAHIKO
IPC: H02P8/14
Filed: 1989-08-24
Abstract: PURPOSE:To prevent generation of an abnormal current by prohibiting simultaneous conduction of transistors for driving a first phase coil and a third phase coil. CONSTITUTION:Collectors of a driving transistor(Tr) Q1 of a first phase coil and a driving TrQ2 of a second phase coil are connected through a diode D1, and the base of the TrQ2 is connected to the collector of the TrQ1 through a diode D2. When the TrQ2 is an ON state and the TrQ1 is an OFF state, a signal A is switched to change the TrQ1 to the ON state. The TrQ2 is not immediately turned OFF due to its switching delay time. The base current of the TrQ1 is escaped to the collector of the TrQ2 by the diode D1 so that the TrQ1 is not turned ON only for the switching delay time. Thus, it can prevent the transistors from damaging.

CONSTITUTION:In the instruction operation, instruction data R(1, j) are stored in respective locatiins of an objective value memory. After initialization in the reproducing operation, the instruction data R on an instruction position 1 are added to integrated value data E in an integrated value memory to calculate objective value data R(m, j) and operation is executed by using said objective value data R(m, j) as an objective value. After repeating the reproducing operation, real tracking data Y(m, j) are inputted and the deviation E(m, j-n)=R(1, j)- Y(m, j) (n is a value obtained by dividing dynamic delay time by a control period) is calculated. A current deviation E(m, 1) is compared with a deviation E(m, k) on a past point of time, and when the compared result is less than a prescribed reference value, the past deviation is adopted and is not stored. When more than the reference value, the current deviation E(m, 1) is stored.
