Title: Lever fitting type connector
Inventor: OKABE TOSHIAKI
IPC: H01R13/629
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a lever fitting type connector capable of maintaining the initial fitting state of a lever without thickening the thickness of the lever and of performing a lever rotating operation easily. SOLUTION: In this lever fitting type connector, a lever 22 is rotatably journalled to a male connector 21 by a boss part 27 to form an engagingly fitting piece 38 for temporarily fixing at the rear-end side lower part of a sidewall 28 of the lever 22. At the rear end lower part of the male connector 21, a temporarily fixing block 37 and the engagingly fitting piece 38 for temporary fixing is set to be engagingly fit on the temporary fixing block 37 in the initial fitting state. In a hood part 32 of a female connector 23, a release plate 39 for releasing engaging-fitting with the temporarily fixing block 37 to the temporary fixing engaging fitting piece 38 is formed. By such constitution, when the male connector 21 is fit into the hood part 32, an engaging projection 30 can be inserted easily into a guide groove 34.  Further, since repulsion is given only to the engagingly fitting piece 38 for temporarily fixing, thickening the thickness of the lever 22 is not required and the rotating operation of the lever 22 can be performed easily.

Title: Mr composite thin-film magnetic head
Inventor: OTOMO MOICHI
IPC: G11B5/39
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic head which enables a high density and high-frequency recording by constituting an upper part magnetic pole with >=2 planes or curved surfaces near a floating surface and constituting these surfaces in such a manner that the angle formed by the tangent on the floating surface side of the surfaces with a gap surface is made smaller than the angles of the other surfaces nearest the floating surface, thereby using a saturation magnetic flux density of a specific value for the upper part magnetic pole. SOLUTION: A high Bs plating film of 1.2T to 2.4T in the saturation magnetic flux density is used for the upper part magnetic pole. A high specific resistance sputter film of, for example, a CoTaZr based amorphous alloy or a high specific resistance sputter film similar to the lower part magnetic pole 11 is used for a middle part magnetic pole 13. The gap surface side of the upper part magnetic pole 18 is composed of the plural curved surfaces near the floating surface 20. The angle 61 formed by the tangent on the floating surface side of the curved surface 22 nearest the floating surface and the gap surface is made smaller than the angles θ2 and θ2' formed by the tangent on the floating surface side of the curved surfaces 23 and 23' further than the floating surface and the gap surface.  As a result, the overwriting characteristics at the high recording density frequency are improved.

Abstract: PURPOSE:To reduce thermal resistance, by providing flat surface on the heat radiating surface of a substrate, fixing a heat radiating block, in which slits parts are provided at several places, with a fixing agent, fixing a water cooling jacket, which has a flat surface, on the surface of the heat radiating block with screws, thereby absorbing warping of the heat radiating block, and closely contacting the block of the water cooling jacket. CONSTITUTION:The opposite surface of a heat radiating block 5 with respect to the fixing surface is machined especially flatly, and a flat surface 5a is obtained. Several pieces of vertical slits are formed in both surfaces alternately, and slit parts 6 are provided at several places. A plurality of screw holes are used for attaching a water cooling jacket 8. Since the slit parts 6 are provided in both surfaces of the heat radiating block 5, the heat radiating block 5 is divided by the slits even if any surface, which is in parallel with the fixing surface, is observed. The block is divided into several parts. Even if warping deformation is yielded in each divided part, the effect to the other part is absorbed by the deformation of the soft slit part 6 due to a force, by which the warping on the side of a printed board 2 is recovered.

Title: Recording/reproducing method and device
Inventor: OKI NOBUTOSHI
IPC: G11B20/12
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To perform defect management by successively detecting defect positions on a medium in a continuous reproducing mode, successively storing positional information related to the defect positions in a memory and recording the positional information recorded in the memory on a table area on the medium in response to the end of the continuous reproducing mode or a reproducing end of a prescribed range on the medium. SOLUTION: A video signal is encoded from an input circuit 10 to be added to a magnetic head drive circuit 12, and a controller 30 decides whether or not an address of an objective sector is registered by reading out the data stored in a defect list of a storage part 28. When the objective sector is registered, the controller 30 decides flag information, and decides the right/wrong of movement to slip processing. In a zone, fixed numbers are counted, and when the processing of prescribed numbers of sectors are ended, the flag information is changed. Since the defect position data are not stored, write-in for a magneto-optical disk 5 is not performed.

Abstract: PURPOSE:To prevent the generation of leaking gas from joints into heater rooms and improve heat transfer efficiency by a method wherein the space formed between a heat treating room and a heat resisting and insulating layer surrounding the heater room coaxially are partitioned airtightly to install heater rooms and joint rooms with exhaust holes. CONSTITUTION:At the surroundings of a firing room 1 an airtight space surrounding the room 1 coaxially is formed. At this space the intermediate part sides and end sides of respective core tubes 2 are airtightly partitioned by circular plate-shaped partition walls 10 to form heater rooms 11 and joint rooms 12.
