Title: Ignition coil for internal combustion engine
Inventor: OOHASHI YUTAKA
IPC: H01F38/12
Filed: 1982-06-30
Abstract: PURPOSE:To facilitate combination with other devices and to realize balancing as well as size reduction of the entire structure by a construction wherein an insertion hole is bored to allow an inserting member to penetrate the interior of either coils or core in the direction perpendicular to main magnetic flux of both coils. CONSTITUTION:Primary and secondary coils are wound with proper insulation therebetween and then coated with a forming material to constitute a coil section 11, which is formed at its center with an insertion hole 11a allowing a rotary shaft of distributor or the like as an inserting member to penetrate therethrough. A core 21 forms a magnetic path common to the primary and secondary coils wound round the coil section 11, and it has an annular form allowing the inserting member to penetrate therethrough. A high voltage terminal 51 is integral with the coil section 11 through the forming material. Changes in magnetic flux incident to intermittent energization of the primary coil induces high voltage in the secondary coil via the core 21. In addition to its own specific function, the ignition coil thus arranged has a function of allowing an inserting member such as a rotary shaft of distributor to penetrate the coils in the direction perpendicular to main magnetic flux thereof.

Title: Single edge type reamer
Inventor: DEIITAA KURESU
IPC: B23D77/02
Filed: 1983-06-28
Abstract: The operating life of the two guide members in a single bit reamer is increased by shaping the peripheral surface of the guide members with a radius of curvature less than the radius of the bore being machined. Contact between each guide member and the bore wall takes place only along a central quest area extending in the lengthwise direction of each guide member. This allows coating of the peripheral surfaces of the guide members with a hard, wear resistant material. Further, the guide members may be fastened to the cutter head by means of a screw situated in a groove extending in the tangential direction along the peripheral surface of each guide member. This increases the lubricating and cooling effect.

Title: Chucking device for magnetic disk
Inventor: KODAMA AKIO
IPC: G11B17/03
Filed: 1985-05-30
Abstract: PURPOSE:To reduce the shake of a drive pin in a chucking mode and to ensure the accurate reading/writing actions by securing a substantial contact between a drive pin and a part of a magnet fixed at the side of a spindle hub and attracting magnetically a metallic hub. CONSTITUTION:A shaft 2 is put with pressure into the hole 12 of a spindle hub 1 and a drive pin 5 is fixed into a hole 13 at the side of the free end of a plate spring 3 fixed to the rear side of the hub 1 by a screw 4. A magnet 6 is set into a groove 15. This C type plastic magnet 6 has a projection part 6a at its single end part which has a contact with the pin 5. The part 6a is set opposite to the hole 13. When the center hub of a magnetic disk is attached to the hub 1 and turned clockwise, the spring 3 bends via the pin 5. Then the pin 5 has a contact with the part 6a. Then the pin 5 is restored when the force applied to the pin 5 is released and a gap W is secured accurately. Thus the positioning is secured with high accuracy and with no change of the chucking state caused by the degree of the force applied to the pin 5. this produces no terror in a reading/writing mode and also secures the interchangeability for improvement of the reliability of a chucking device for magnetic disk.

Filed: 1986-05-21
Abstract: PURPOSE:To reduce a read error by comparing a head read signal of a perpendicular magnetic recording medium with a reference level, integrating the result and synthesizing it with the read signal or the reference level and using the output as the read signal. CONSTITUTION:A read signal from a magnetic head 20 is amplified and noise is eliminated by an LPF24, the gain is adjusted VR2, amplified 26 and compared 28 with a prescribed reference level.
