Title: Connecting structure of light transmission body
Inventor: KOIKE YASUHIRO
IPC: G02B6/26
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To make it possible to execute the connection of optical fibers with high performance with practicably sufficiently less connection loss even if the cause for the connection loss is permitted to some extent by making both light transmission bodies to be connected hold a silicone gel pad pressing this pad at their respective end faces. SOLUTION: An adapter 3 has a sleeve 7 of nearly the same inside diameter as the outside diameter of a ferrule 5 of a plug connector 2 attachably and detachably in its central part. This sleeve 7 holds the silicone gel pad 8 in nearly the central position in its longitudinal direction. When the plug connector 2 is fitted to this adapter 3, the ferrule 5 fits to the sleeve 7. When the fitting of the plug connector 2 to the adapter 3 attains a prescribed state, both fibers 6, 6 are slightly deformed from both sides and are held while the silicone gel pad 8 is deformed. The end faces 6f, 6b are brought into secure and tight adhesion with the silicone single pad 8 and the optical connection of both optical fibers 6, 6 is executed.

Title: Head feeding device
Inventor: YAMAMOTO MASARU
IPC: G11B21/08
Filed: 1985-11-28
Abstract: PURPOSE:To eliminate the necessity of a motor as a driving source by making the reciprocating motion of an electromagnetic movable coil into a driving source, and after the reciprocating motion is converted into a rotating motion, shifting a head with the converting mechanism converted to a linear motion. CONSTITUTION:By supplying an electric current pulse to a movable coil 23, the coil 23 is reciprocated and works as the driving source of a head feeding. A ratchet gear 29 and a feeding claw 31 constitute the first converting mechanism to convert the reciprocating of the movable coil 23 into the rotating motion. A rack gear 38 formed at the tip of a scanning arm 39 is geared with a small diameter gear 37 to rotate in a single body with an interlocking gear 36, and the second converting mechanism to convert the rotation of the small diameter gear 37 into the linear motion is formed.

Title: Tension testing device for resin
Inventor: FUJII MASAHIRO
IPC: G01N3/08
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To permit test in a wide range from a low speed to a high speed by providing a pair of upper and lower clamps which are protruded at the movable part of a servo motor for driving a direct-acting actuator, arranged between a freely vertically movable crosshead and a rack flat plate, and each grip the ends of a resin tensile test piece. SOLUTION: This device is composed of a rack 3 erected on a bottom plate 1 and provided with a horizontal rack flat plate 3a, a direct-acting actuator 10, a servo motor 20, a freely vertically movable crosshead 16, upper and lower clamps 50 and 40 to grip the ends of a resin tensile test piece, etc. After a pair of the upper and lower clamps 50 and 60 grip both ends of the resin tensile test piece, the servo motor 20 is driven to move the crosshead 16 upwards. As there is a gap between the upper surface of the crosshead 16 and the lower surface of a stopper 54, the upper clamp 50 starts to move at the instant that the upper surface of the crosshead 16 has reached the lower surface of the stopper 54. Therefore, it is possible to transmit operational speed to the resin tensile test piece independent of the initial speed of the crosshead 16.

IPC: H01L23/34
Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To provide an SAW(surface acoustic wave) device having stable characteristic and a long life and its manufacturing method. SOLUTION: The line width W1 of the first metallic layer 6, which is positioned on the side of a piezoelectric substrate 2, of each electrode finger 5 of the comb-shaped electrodes 4 of exciting electrodes 3 is a value to be decided by the electrical characteristic of a surface acoustic wave device 1 and is a intrinsic value to be decided nearly uniquely in order to obtain a frequency characteristic requested on a prescribed piezoelectric substrate 2. The line width W2 of the second metallic layer 7 positioned on a remote side from the substrate 2 can optionally be set since it is independent from electric characteristic such as the frequency characteristic of the SAW device 1. The width W2 of the layer 7 is made larger than the width W1 of the layer 6 to improve the radiation effect of the device 1.

Title: High frequency element evaluating device
Inventor: INOUE AKIRA
IPC: G01R31/26
Filed: 1988-10-21
Abstract: PURPOSE:To prevent the reflection of an unnecessary high frequency signal by changing the width of a signal line so that the respective characteristic impedances of a first part being right under a press-contacting bar and a second part except a first part become equal to each other. CONSTITUTION:A lead wire 4 comes out of a package 1. On a dielectric substrate 2, a signal line 3 is provided. By pressing the lead wire 4 by a press- contacting bar 5, the lead wire 4 and the line 3 are brought into contact with each other. According to this constitution, in the line 3 on the substrate 2, width of a first part being right under the press-contacting bar 5 is changed so that characteristic impedances of a first part being right under the press- contacting bar 5 and a second part except a first part become equal to each other. In such a manner, the reflection of an unnecessary high frequency signal is not generated, and a high frequency element can be evaluated exactly. In this regard, it is also possible to change the thickness of the substrate 2 of a first part instead of changing width of the line 3 of the first part.

Patent JP-S61144176-A (JP)
Title: Image pick-up device
Inventor: HIEDA TERUO
IPC: H04N5/335
Filed: 1984-12-18
Abstract: PURPOSE:To eliminate an influence of the screen even when an essential accumulating period is short by decreasing a saturated charge quantity of a picture element from during the essential accumulation while the charge, which is accumulated in a photodetecting part of an image pick-up means and once removed, is accumulated. CONSTITUTION:A time setting circuit 104 generates a pulse being late for the time which subtracts the time set by a switch 105 based upon a vertical fly-back line pulse (VD) from a vertical period, and sets an essential accumulating time T2. A driving pulse generating circuit 106 generates a pulse phiI necessary for the vertical transfer by the pulse from the circuit 104. An ABH change-over signal generating circuit 110 discriminates whether or not an accumulating condition of the unnecessary charge (period T1) is an essential accumulating period, by an output of a VD and the circuit 104, and executes the action to change over the output of a switch circuit 111 and executes the action to change over an ABH to an ABH1 and an ABH2. Consequently, even when the servo control is executed by 112 and 113 so that the output level of a sensor 1 can be constant and the charge quantity formed in a period T1 is increased, the blooming due to an overflow can be prevented.

The transferring process of a 1st sheet is carried out in this state and the developing and processing processes on and after a 2nd sheet are also carried out in a state where the electrostatic latent image is on the polarity side to which the photosensitive body 1 in not sensible. Therefore, the potential on the surface of the photosensitive body 1 hardly drops in each process on and after the 2nd sheet and few disturbances are produced in the latent image. Therefore, clear copied pictures can be obtained.
