Abstract: PURPOSE:To prevent the unexpected movement of a moving member during cassette loading, by coupling a cassette holder lock lever with a tape loading moving member lock lever. CONSTITUTION:When a cassette holder 3 is loaded at a cassette loading position and a holder lock lever 82 is rotated to a lock position, the sliding of an interlocking slider 143 rotates a conversion lever 147 as shown by an arrow and a detection slider 136 slides as shown by an arrow Q. At this time, the projection 141 of the detection slider 136 presses the projection 140 of a conversion lever 133 is rotated as shown by an arrow l' to rotate a ring lock lever 127 as shown by an arrow m', unlocking a tape loading ring 122. For unloaing, on the other hand, a tape loading slider 123 is moved as shown by an arrow k' and returned as shown by an arrow (k) to stop. Consequently, the detection slider 136 is slid as shown by an arrow Q' to rotate a holder lock lever 83 to an unlocking position through the conversion lever 147 and interlocking slider 143.

Abstract: PURPOSE:To eliminate an influence of carrier components without reducing a high frequency component of a base band component, by laminating and placing the first quartz plate, the second quartz plate and the third quartz plate so that the second quartz plate is positioned in the middle, and dividing one incident light into several lights. CONSTITUTION:A quartz plate 11 divides incident light into normal light and abnormal light, and a main surface 14 on which these normal light and abnormal light exist makes an angle of theta1 (for instance, +45 deg.) to a horizontal scanning direction H. As for a quartz plate 12, a main surface 15 on which the normal light and the abnormal light exist coincides with the horizontal scanning direction. As for a quartz plate 13, its main surface 16 makes an angle of theta2 (for instance, -45 deg.) to the horizontal scanning direction H. These three quartz plates 11, 12 and 13 are laminated and stuck so that the second quartz plate 12 is positioned in the middle. Also, they are placed in an incident light path so that the quartz plate 13 comes to the nearest position to a solid-state image pickup element side.

Abstract: PURPOSE:To enable drilling to be directly performed promptly sensing a reference hole position mark without applying a particular mark or work on an inner metal layer by marking a sign by paint in the vicinity of the reference hole position mark, slightly appearing in a surface of an outer metal layer, and picture processing this sign obtaining coordinates in the vicinity of the reference hole position mark. CONSTITUTION:A sign 6 is marked by paint in the vicinity of a reference hole position mark of an inner metal layer coming out in a surface of an outer metal layer 1a of a multi-layer piled plate 5. Next the sign 6, marked on the surface of the base plate 5, is detected by a CCD camera 8, and coordinates of the sign is measured. With this coordinate serving as the reference, the multi- layer laminated plate 5 is moved in a manner wherein the vicinity of the reference hole position mark is placed almost just below a centripetal device (comprising X-ray camera 9 and image receiver 10). Thereafter, the centripetal device, picture processing an image of the reference hole position mark previously formed in the inner metal layer, calculates the center of the mark, and this position is directly drilled by a drill unit 11.

Title: Production of hot rolled steel plate having less surface defects in edge part
Inventor: SUGAWARA TAKESHI
IPC: B21B1/02
Filed: 1982-02-15
Abstract: PURPOSE:To suppress the formation of edge seam flaws on rolled steel plates and to improve the yield of steel plates in the stage of hot rolling steel slabs and producing the steel plates by forming the inside of the opposed short sides of the slabs into recessed shapes beforehand. CONSTITUTION:In the stage of producing a steel plate by hot rolling a slab of stainless steel or the like, the mutually opposed short sides 2, 2 in the cross sections of the slab are formed to recessed shapes to form recessed surfaces 2' on the side surfaces of the slab. The metal flow by the plastic deformation in the stage of hot rolling of such slab decreases the transverse spreading of the surfaces 2' to the outward from corners 5 and suppresses the formation of edge seams 8 as the linear surface flaws in parallel with the rolling direction in both edge parts of the rolled steel plate, thereby preventing the decreases in the yield of the steel plate owing to edge cuts.

Title: Ignition coil
Inventor: HOSOKAWA NOBORU
IPC: H01F38/12
Filed: 1979-02-23
Abstract: PURPOSE: To stabilize the operation of an ignition coil at a low temperature by using insulating liquid of low freezing point as insulating medium.  
     CONSTITUTION: An excessive increase in pressure due to an increase in volume at a high temperature is prevented by using fluorocarbon 114B2 as insulating medium and by filling the fluorocarbon in a container providing that small space is left. The freezing point of the insulating liquid is -110°C and the gas has high insulation and dielectric strength as four times as that of N 2  at 25°C. And the gas also maintains high insulation when bubble is mixed in liquid as like the time of boiling. Therefore, high insulation is maintained even if the boiling is occurred around the coil by the heat of coil, and the coil is effectively cooled by high thermal conductivity and latent heat of evaporation. As low freezing point flon, freon 11 and freon 113 are also acceptable. In this composition, an ignition coil which stably operates in the atmosphere down to the freezing point of freon is obtained.

Title: Apparatus for taking out power from superconducting energy
Inventor: KUMAGAI MASAHIKO
IPC: H01L39/14
Filed: 1988-02-02
Abstract: PURPOSE:To control a voltage at the time of taking out power from superconducting energy, by a method wherein a magnetic flux generated by a permanent current flowing through a superconducting coil is shielded and passed repeatedly by a magnetic shield plate to generate an electromotive force in a coil wound on a second core. CONSTITUTION:In a state wherein a permanent current flows through a superconducting coil 3 and a power is stored, a certain magnetic flux 8 is generated from a core 1 by the superconducting coil 3. When a magnetic shield disk 4 is rotated around the central point 6 on the occasion, the magnetic flux 8 passes through a core 2 when a gap 5 of the disk 4 comes between the core 1 and the core 2, and the pass of the magnetic flux 8 is interrupted when a shield part comes therebetween. An electromotive force is generated in a coil 7 wound on the core 2 by this change in the magnetic flux, and a voltage E is obtained from the opposite ends of the coil 7. A desired voltage value is obtained by changing the winding of the coil 7.
