Title: Punching method for numerous pieces
Inventor: SHIMOJO NORIO
IPC: B26F1/02
Filed: 1988-12-27
Abstract: PURPOSE:To make a hole interval accuracy the same accuracy as in a lot of pieces simultaneous punching by an integrated punching die and to make the punching capacity of a press sufficient the same capacity as in the punching of one hole, by using an integral die as a lot of pieces punching die. CONSTITUTION:A case 1 to be perforated is fixed by positioning by inserting from an end part to a lower die 3. The end part of the lower die 3 is supported by a cradle stopper 2a. In case of taking the stroke of a press machine as (h) now, a moving intermediate piece 10 equivalent to height (h) is located on a punch 6c. So, only the punch 6c is descended when a lift 4 is descended and a hole (c) is perforated. The moving intermediate piece 10 is then moved on a punch 6b by a cylinder 9 when the lift 4 is moved up on completion of punching by the punch 6c, then the lift 4 is descended and a hole (b) is perforated. Thus holes a-c are perforated on the case 1 hole by hole by moving the moving intermediate piece 10 by the cylinder, etc., in order at the punch upper part.

Title: Optical magnetic recording/reproducing device
Inventor: MIYAKE TOMOYUKI
IPC: G11B11/105
Filed: 1993-12-24
Abstract: PURPOSE:To secure a wide magnetic field area by winding a plurality of coils on one magnetic field modulation recording magnetic head and providing coil driving circuits by the same number as the coils or below. CONSTITUTION:A relatioship L infinity  (S.n<2>) among the inductance L of the magnetic head, the number of wound coils and the sectional area of a magnetic core is obtained, a counter electromotive force=L.(di/dt). When the coil of the magnetic head is equally divided into (m) pieces, inductance Lm per coil is L/m<2>. Thus, a magnetic field inversion &ed (di/dt) is multiplied by m<2>. However, when the same recording signals are simultaneously given to all the coils, since L is the number of magnetic fluxes per unit current, Lm is L/m. For instance, in the case where a coil is equally divided into three, L3 is 1/3 and thus the magnetic field inversion speed is multiplied by three. As a result, when the coil driving circuits the same in number as a plurality of coils are used, a magnetic field inversion is performed at a high speed without changing the sectional area of the magnetic core.
