Title: Distance measuring device
Inventor: TAMURA SHIYUUICHI
IPC: G02B7/32
Filed: 1983-12-05
Abstract: PURPOSE:To measure the distance of an object without placing the object to be focused in the center of a screen, by rotating a light projecting lens and a light receiving lens, whose optical axes are off respective rotation center lines, around rotation center lines synchronously with each other. CONSTITUTION:A light projecting lens 2 and a light receiving lens 4 are shifted from respective rotation center lines by the same quantity and are rotated synchronously with each other while keeping the same shift directions, and the luminous flux from a light emitting element 1 is projected from the light projecting lens 2 to an object in an object field 3, and the reflected light is focused onto a light receiving face of a photodetector 5 by the light receiving lens 4. The object field 3 is scanned in the direction of an arrow to measure the distance successively. Since the incidence position of the refected light on the light receiving face of the photodetector 5 is different by the distance of the object, variation of electric outputs from two output terminals of the photodetector 5 is obtained to measure the distance of the object.

IPC: G11B5/105
Filed: 1983-12-09
Abstract: PURPOSE:To improve the defective supply of casting resin to a tape rubbing surface of a magnetic head in a resin casting process, by impressing a magnetic field to a holding case which injects the synthetic resin containing magnetic powder and supplying the synthetic resin into the holding case together with the magnetic powder. CONSTITUTION:A prescribed amount of magnetic powder 6 is added to the synthetic resin 5 which used for adhesion of a core 2, etc. This resin 5 is poured into a holding case 1. Thus the powder 6 contained in the resin 5 is attracted by a magnet 9 and moved to the side of a tape rubbing surface. The resin 5 is also moved together with the powder 6 toward the surface 1a in accordance with the shift of the powder 6. Unlike a conventional process, the resin 5 is easily supplied into a gap 4 on the surface 1a between the case 1 and the core 2 together with the shift of the powder 6. Thus the gap 4 is completely filled with the resin 5 and the powder 6. This reduces extremely the defective supply of the casting resin to the tape rubbing surface of a magnetic head.

Title: Contact break detecting apparatus of electromagnetic contact device
Inventor: DOI SHIGEYOSHI
IPC: G01R31/00
Filed: 1989-09-08
Abstract: PURPOSE:To easily carry out maintenance work by providing an interlocking contact interlocking with a main contact and using an ON/OFF signal of said interlocking contact as a detecting means for detecting a break of said contact. CONSTITUTION:Coil terminals, a1, a2 of an electromagnetic contact device 1 are connected to terminals A1, A2 of a break detecting device 2. When an operating coil is turned ON, an operating signal detecting switch 3 is turned ON and an output contact B of the switch 3 is turned OFF. When the operating coil is kept ON, a break detecting switch 5 is not excited even when a main contact is in the ON state. Then, when the operating coil is turned OFF, the switch 3 is turned OFF. However, this action of the switch 3 is started later than a delay circuit 7, and therefore the timing when the B contact is turned ON becomes later than the main contact. When the main contact is turned OFF, an interlocking contact 4 is turned OFF as well. Therefore, during the normal operation, the switch 5 is not excited. In contrast, if the main contact is out of order as a result of the welding or the like, the switch 5 is excited even when the operating coil is turned OFF, whereby the output contact generates a signal.

Abstract: PURPOSE:To execute a spring pressure adjustment in a state that a carriage has been assembled to a device body, by providing a spring pressure adjusting means for executing an adjustment by tightening or loosening a screw of a spring pressure of a needles holding spring. CONSTITUTION:A spring pressure of a needle holding spring 16 for working on a lead screw 14 works by depending on a pressing force of a round screw 21. That is, for instance, in case the pressing force to the needle holding spring 16 has been strengthened by moving the round screw 21 in the direction as indicated with an arrow 23a, a spring pressure to the lead screw 14, of the needle holding spring 16 also works strongly, and on the contrary, when the pressing force is weakened by moving the round screw 21 in the direction as indicated with an arrow 23b, the spring pressure or the needle holding spring 16 also works weakly. In this way, the spring pressure of the needle holding spring 16 can be varied by adjusting the round screw 21, and accordingly, the spring pressure which has been generated by a variance of the spring pressure of the spring 16 can be compensated by adjusting the round screw 21, and a stable quality can be secured.

Title: Organic sulfur-contained silane modified oxide and modified surface light patterning oxide
Inventor: ICHINOSE NOBUYUKI
IPC: G03F7/26
Filed: 1993-09-17
Abstract: PURPOSE:To enable the easy reforming and patterning of the organic molecule surface-modified solid surface and enable the specified pattern arrangement of protein molecules by disposing a disulfide organic group substituted silane monomolecular layer on the surface. CONSTITUTION:A disulfide organic group substituted silane monomolecular layer is disposed on the surface to obtain a surface modified oxide, and light is irradiated to the obtained surface modified oxide through a mask pattern to form a modified surface light patterning oxide with the disulfide group cleaved by light on the irradiated surface. With this irradiation, disulfide is cleaved by light on the irradiated part so as to form a sulfur oxide in an oxygen atmosphere, for instance, by the reaction of the formed radical. This oxide has low reaction activity to an organic molecule such as protein. At the non- irradiated part, on the other hand, disulfide is easily reduced and transformed into a thiol group. This thiol group fixes organic molecules such as protein, peptide and a polymer under the existence of a cross linking agent so as to enable the formation of a pattern.
