Title: Gate turn off thyrister
Inventor: ODAI TSUNEGO
IPC: H01L29/74
Filed: 1989-04-04
Abstract: PURPOSE:To safely and surely turn ON an element by a comparatively small current by forming an emitter shorting part in a ring type in a projection region between arrangement rings of unit gate turn OFF thyrirters (GTO thyrister). CONSTITUTION:An emitter shorting region 16 is not formed in the projection region of an N-type second emitter layer 14. It is formed and constituted in the ring type, in a projection region of a region with which a gate electrode 6 of a P-type second base layer 13 in a boundary part of radially arranged unit GTO thyristers 2 is connected. Hence, a current path in a buffer layer 15 in the projection part of the N-type second emitter layer 14 is lengthened in the transversal direction on a P-type first emitter layer 11, and reaches the emitter shorting region 16, 16'. Thus a short resistance can be increased. There by collector current is made to easily flow also through the P-type first emitter layer 11, and the GTO thyrister can be safely and surely turned ON.

Title: Device for protecting electronic equipment from static electricity
Inventor: SAWANO KENJI
IPC: H05F3/02
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To prevent the electrostatic breakdown of electronic equipment caused by static electricity applied from a gap or the like in an insulating casing. SOLUTION: A printed circuit board 6 placed near the joint (a) between a front panel 1 and a main casing 2 is provided with a conductor pattern of reference potential immediately near the joint (a) in such a way that the pattern is exposed.

Title: Magnetic head
Inventor: YOKOYAMA OSAMU
IPC: G11B5/265
Filed: 1985-04-22
Abstract: PURPOSE:To decrease the interference of a magnetic flux and to decrease noise even if a head causes off-tracking by forming the 1st head of the magnetic path parallel with a substrate plane and the 2nd head of the magnetic path perpendicular thereto on the same substrate and making the width of one magnetic pole wider than the width of the other. CONSTITUTION:The magnetic path of the head HE for erasing joined with 'Sendust(R)' films 13, 14 in a joint part 20 is constituted on the slider substrate 11 and the head HW for recording and reproducing consisting of a coil 12 and a protective 30 are formed thereon. Erasing is executed by the magnetic pole of the head for erasing progressing in an arrow H direction with respect to a recording medium M and thereafter recording is executed by the magnetic pole of the head for recording and reproducing having the slightly narrow width. The noise is therefore decreased without picking up the previous signal in spite of some offsetting and since the magnetic path of the head for erasing is parallel with the substrate plane and since the head for recording and reproducing exists within the plane perpendicular thereto, the influence to be exerted to the mutual magnetic fields is small and the disturbance of the magnetic field distribution for recording is decreased.

Abstract: PURPOSE:To secure the image quality of a restored image even in case of a high compression rate for image compression by dividing image data to blocks each of which consists of plural picture elements and subjects image data of each block to orthogonal transformation and assigning bits to only change points to compress data. CONSTITUTION:Image data photographed by an X-ray camera 3 is stored in an original image data memory 11 and is immediately read out and is divided into plural blocks by a block dividing part 12b. Each divided block is subjected to orthogonal transformation, for example, Fourier transformation by an orthogonal transforming part 13a. In a compressing part 14a, a feature detecting part 18 subjects transformed data to linear differentiation and quadratic differentiation to detect wave front values and change points as features. Bits are assigned to only wave front values and change points by a bit assigning part 19 to compress data. This compressed data is stored in an image data memory 16. Thus, an image having distinct edges is obtained though the compression rate is high.
