Title: Focus controller
Inventor: HIRASAWA KAZUO
IPC: G11B7/09
Filed: 1983-05-23
Abstract: PURPOSE:To prevent a movable part for making a shift in the position of a light spot for reading a signal from moving unnecessarily by providing a position servo loop which controls the movable part with a signal indicating the position of the movable part, and holding the movable part stably. CONSTITUTION:When an on-instruction H of a focus servo is applied to a terminal 20, the output of a position setting signal generator 28 increases. A differential amplifier 27 compares a position detection signal from an FM detector 26 with the position setting signal as a reference signal, and its output is supplied to a driving coil through a driving circuit 15 from a loop switch 14. This position servo loop is so controlled by the differential amplifier 27 as to equalize a position detection signal to the position setting signal, which, however, increases in a slope shape. When the distance between a disk 4 and an objective 5 is optimized by said movement, a focus servo system starts operating, the loop switch 14 is placed on the side of a contact P2, and the position servo loop does not move to and from the movable part 3 any more, so that stable holding force operates on the movable part 37.

CONSTITUTION:As a multiple cross section, a cross section of a pin is a circle and a cross section of two or more separated conductor parts is a continuous shape or a noncontinuous shape in a concentric circle shape with reference to the center of the pin; in either case, at least one conductor part is formed at the inside; a signal layer 1, an earth layer 3 or a power-supply supply layer 4 corresponds to the conductor part. A tip part of the conductor part on the side which is inserted in a substratum board has a gradually long stepped shape toward the central part, when a board where a printed wiring circuit has been formed in a position corresponding to a position of the tip part is prepared, a wiring structure of a printed-circuit board can be simplified. An intermediate part may be constituted of any of an insulator, a resistor and a dielectric. As a result, the density of a signal line per unit area of the pin for board use can be enhanced sharply; a semiconductor can be mounted at high density; a signal propagation speed can be made high.

IPC: B21K21/16
Filed: 1979-07-20
Abstract: PURPOSE: To save manufacturing costs by restraining the outer circumference of a flanged blank pipe by a container and reducing the blank by a mandrel mounted with a punch at its nose.  
     CONSTITUTION: This is a process for production of long-sized hollow material which does not require a large amount of equipment costs and is adapted to a wide range of sizes. More specifically, a flanged blank pipe 1 is fitted into the center hole 2' of a container 2 up to its flange. A tapered or spherical punch 3 of a diameter larger than that of a mandrel 4 is removably mounted to the nose of said mandrel. The mandrel 4 thus set with the punch 3 is inserted into the blank pipe 1 and is pushed to advance in the arrow direction, by which the wall thickness of the blank material 1 is reduced by the punch 3 and is elongated long in the container 2 and the blank pipe is thus reduced. At this time, a clearance (d) between the blank pipe 1 and the mandrel 4 is formed to cool C the hollow material portions right after the working behind the punch 3. The punch 3 having finished the reducing is separated from the mandrel 4 and is immediately cooled in a water vessel 5. This makes possible working at the capacity ≤1/10 that in the prior art.
