Title: Key
Inventor: SUZUKI MICHIRO
IPC: F16D1/02
Filed: 1992-02-12
Abstract: PURPOSE:To fix a key without an impact on a bearing by superposing the taper recessed parts of a pair of blocks in a facing condition on each other, and making a part of the pin peripheral surface, first, come into contact with the central part in the peripheral direction of the taper recessed part when a taper pin is inserted into the taper recessed part. CONSTITUTION:When a pair of blocks 5 are made to face each other, and a taper pin 3 is disposed between them to be inserted into a key way between shafts 7, 8, both the side parts of the taper pin 3 come into contact with the central part of the semicircle of the respective blocks 5 by 10% of a complete circle, a non-contact part 13 is formed by 90% around respective block side wall surfaces 12, and a small clearance 9 is formed between the block 5 and the key way. When a tightening means 6 is screwed in a threaded part 2 to be rotated, and the taper pin 3 is relatively-moved to the blocks 5, the clearance between the block 5 and the key way is eliminated to form the small clearance 9 between the side wall surface 12 of the block 5. At this time, the non-contact part 13 becomes approximately 10%, and the contact surface of the taper pin 3 with the taper recessed part becomes approximately 90%. It is thus possible to prevent an impact from being given to a bearing for no damage to the bearing at the time of installing a key.

Title: Magnetic field modulation overwriting system for photomagnetic recording device
Inventor: SUZUKI HIROSHI
IPC: G11B11/105
Filed: 1986-03-17
Abstract: PURPOSE:To directly execute overwriting without executing an erasion once, by providing an external write coil, and prescribed a direction of a recording magnetic field by turning on and off this coil at the time of write heating by laser light. CONSTITUTION:At the time of writing in the upward direction (shown in a figure) of a write magnetic field Ho in a magnetic domain of a recording layer 5, when its magnetic domain is projected by strong laser light 9 and heated to the vicinity of a curie temperature, its holding force drops to Hr. In this case, the magnetic field Ho is impressed by a write coil 8, and when a condition of Hr<Ho-Hi (Hi denotes a magnetic field by a thin film permanent magnet 2) is set, a magnetic field of its magnetic domain is governed in the upward direction (shown in figure) of the magnetic field Ho. As a result, a disk advances by one magnetic domain portion, and in the magnetic domain after the laser light 9 has been eliminated, a magnetization in the upward direction is left as a residual magnetism. Subsequently, in case of overwriting in the downward direction  , the magnetic field Ho is not impressed, and an external magnetic field for governing the magnetic domain being a write part is only the magnetic field Hi. Accordingly, a condition of Hi>Hr is set by the laser light 9, and the direction of its magnetization is inverted in the downward direction and recorded.

Title: Image pickup device
Inventor: KAMOTANI YOSHIYASU
IPC: H04N5/225
Filed: 1985-03-25
Abstract: PURPOSE:To make the switching operation of photographing convenient and to reduce switching time by providing a rotation supporting part which maintains an image pickup camera and has a rotatable table with placing face that an image pickup object is provided. CONSTITUTION:By placing an original to be photographed on an original face 9 and rotating a camera 1 centering a rotation supporting part 5 in the direction of an arrow C, the original on the original face 9 is photographed. When a blackboard or the other object is photographed, with keeping a state that the camera 1 is photographing the original, an original table 8 is rotated centering the rotation supporting part 5 in the direction of an arrow A or B and is faced against the blackboard or the other object and afterwards, photographing is performed by rotating the camera 1 in the direction of an arrow D centering the rotation supporting part 5. The rotation of the camera 1 centering the rotation supporting part 5 in the direction of the arrow or D is enough for an alternate switching operation between the photographing of the blackboard or the other object and that of the original because a positioning relation in a parallel direction between the camera 1 and the original face 9 is decided unequivocally. Thus, the switching operation is easily performed and the switching time is reduced.

Filed: 1991-03-25
Abstract: PURPOSE:To provide an optical information recording medium with a film thickness of a recording layer uniform over the entire surface of a disc substrate. CONSTITUTION:An organic solution 2 of an organic optical recording material is dropped onto a disc substrate 1 held on a turntable 5 with a syringe 3 held by a holding means which moves at a specified speed from the outer to inner circumferential side of the substrate and spin coating is performed so that a changing range of a reflection factor is below + or -0.03% over the entire surface of a recording layer on the substrate 1 after the drying thereof to make an optical information recording medium. BY this method, a protective film is formed on the recording layer as required. Since the changing range of the reflection factor of the entire surface of the recording layer is below + or -0.03%, tracking characteristic is excellent. The syringe moves from the outer to inner circumferential side and a film is formed to obtain a large reflection factor evenly over the entire surface thereof. Thus, an equal optical recording characteristic is obtained thereby enabling the prevention of injury or the like whether a protective film is provided or not.

Title: Internal abnormality detecting method for gas insulation equipment
Inventor: HASEGAWA SHIN
IPC: G01R31/00
Filed: 1990-03-13
Abstract: PURPOSE:To securely detect abnormality of a contact part in a tank by providing a reference point where the influence of the contact part is not exerted outside the tank and comparing the temperature at the reference point with the temperature at a measurement point corresponding to each contact part. CONSTITUTION:Temperatures measured by contact type thermometers 85 - 87 of breakers A - C are compared with a reference temperature measured by a thermometer 88 provided at the reference point and when a temperature difference from the reference point is larger than a certain extent, it is judged that the contact part is abnormal. At this time, the range of temperature differences between the measurement points and reference point in a normal contact state is inputted to a comparing means such as a computer previously and then abnormality of any contact part can easily be decided. The temperature differences are measured at constant intervals of time and their variation is monitored to predict the progress of abnormality and the period of repair inspection. Further, the abnormality is detected by comparing the reference point and respective measurement points, so even if plural measurement points become abnormal at the same time, they can accurately be detected.
