Title: Lens type connector for optical fiber
Inventor: MASUDA SHIGEFUMI
IPC: G02B6/32
Filed: 1979-12-28
Abstract: PURPOSE:To easily obtain the parallelism of two optical fibers by polishing the end faces of the optical fibers in manner as to incline by a predetermined angle from the optical axis thereof and parting the center of lenses from the optical fiber end faces by a distance equal to the focal length thereof. CONSTITUTION:It is assumed that the optical axis 3 of an optical fiber 2 is off- centered by a distance Y from the central axis of a plug 7, that is, the ideal optical axis 4 of the connector. The end face 21 of the optical fiber 2 is inclined on the side of a spherical lens 1 by the angle theta by the formula I with respect to the surface 22 orthogonal to the optical axis 4. On the other hand, the spherical lens 1 is disposed on the extension of the optical axis 3 by parting its center from the center of the end face 21 by a distance equal to the focal length f of the lens 1. This results in that the luminous flux emitted from the optical fiber 2 is emitted on the optical axis 4 after it has passed the lens 1. Since the other lens 1' and optical fiber 2' are constituted in a similar manner, the result is that the luminous flux enters the optical axis of the optical fiber 2'. Hence, with such constitution, the parallelism between the two optical fibers may be obtained easily.

Title: Brake for linear motor table
Inventor: ITO OSAMU
IPC: B60L13/03
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To stop a table under a fixed state even if power supply is interrupted by an arrangement wherein a retainer is urged oppositely to the moving direction through a linear solenoid. SOLUTION: An urging means, i.e., a coil spring 8, has one end engaged with the stop plate 15 of an outer cylinder 6 while being enclosed thereby, and the other end for urging a retainer 4 oppositely to the moving direction through a solenoid 7 by pressing the end part thereof. When the solenoid 7 is conducted, a plunger 7a is pulled in against the the coil spring 8 and a ball 5 is separated from the tapered face 6a of the outer cylinder 6 in the direction shown by an arrow P. The ball 5 rolls freely as a shaft member 2 moves so that the shaft member 2 can move freely. When power supply to the solenoid 7 is interrupted, the retainer 4 is urged to move by the coil spring 8 and the ball 5 is stopped on the tapered face 6a of the outer tube 6 through wedge action of the shaft member 2. According to the structure, a table is stopped under fixed state when power supply is interrupted.

Abstract: PURPOSE:To improve the quality of picture and power source efficiency with a smaller coil by arranging an inclined magnetic field coil and a high frequency shielding body outside a high frequency coil to make a support of the inclined magnetic field coil transit a high frequency magnetic field. CONSTITUTION:A Faraday shield 21 as high frequency shielding body is mounted on an internal surface of an inner cylinder member of a superconductive magnet 2, for example, by sticking to be kept at a ground potential. An inclined magnetic field coil support 9 is set concentrically into an inertial chamber of the Faraday shield 21.

A high frequency magnetic flux generated when a high frequency power is applied to the high frequency oil 6 is as shown by the broken line. The high frequency magnetic field is transmitted through the inclined magnetic field coil support 9 thereby forming a flux distribution almost the same as that when there is no inclined magnetic field coil.

Abstract: PURPOSE:To change the number of bits capable of being input and output without altering chip itself at all, to improve the general-purpose properties of the chip and to reduce cost by bonding an exclusive pad to a pin for supply voltage and a pin for ground voltage. CONSTITUTION:In an example in which two kinds of selection of eight bits or nine bits is enabled as the number of input/output data, an output from a NAND circuit C16 reaches a high level because an exclusive pad P1 reaches a GND level D2, a low level, when the exclusive pad P1 is connected to the GND pin D2 by wire bonding, and a node N11 reaches the low level by a NOT circuit C14, and an output circuit C11 for ninth bit is input. Since an output from a NOT circuit 13 reaches the high level, an output from a NOR circuit 17 the low level and an output from the NOT circuit C15 the high level, a node N12 reaches the high level. Since the node N11 reaches the low level, a P channel type MOSFETQ11 is turned OFF. Likewise, an N channel type MOSFETQ12 is turned OFF Accordingly, the output circuit C11 for ninth bit is inactivated.
