Title: Method and apparatus for inspection of heterogeneity of translucent substance
Inventor: TANABE MASARU
IPC: G01N29/04
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which the optical heterogeneity of a translucent substance can be detected with high sensitivity and at high speed. SOLUTION: Laser light L is introduced into a transparent substrate 1 from one side (a) of the transparent substrate 1. On the other hand, an ultrasonic beam U whose frequency is changed is propagated inside the transparent substrate 1 from one side (b) of the substrate 1. When the laser light L is incident on a region whose refractive index is changed due to the ultrasonic beam U, first-order diffracted light L1 , first-order diffracted light L2 ,... due to the Bragg diffraction are generated in addition to zero-order light L0 which travels straight without being diffracted.  The zero-order light L0 , the first-order diffracted light L1 , the first-order diffracted light L2 ,... are propagated while the total reflection is being repeated on the main surfaces H and the edge T of the transparent substrate 1, they are set to a state that the light is confined mostly inside the substrate 1, and the light is spread everywhere inside the substrate 1. When a heterogeneous part such as a flaw or the like exists in the transparent substrate 1, the light is not reflected totally on the surface of the substrate 1, and the light is leaked from the surface of the substrate 1. When the leaked light is detected, the heterogeneity of the transparent substrate 1 can be inspected.

Title: Finely adjusting apparatus for optical apparatus
Inventor: SEKIGUCHI KYOJI
IPC: A61B3/10
Filed: 1989-03-10
Abstract: PURPOSE:To achieve higher reliability and durability of the apparatus by providing a switching means comprising a magnetic circuit which drives a magnetic rotor to rotate by a magnetic induction and a current variation detecting circuit for detecting variations in a drive current thereof. CONSTITUTION:A permanent magnet 12 within a shaft section 3b is turned with a circuit comprising a magnetic core 21, an electric circuit driving circuit 23 and the like together with a rotating shaft 11. Here, when a pushbutton is depressed, a press shaft 9a lowers to block the rotation of the rotating shaft 11 pressing a head thereof. As a result, a reverse electromotive force is ceased as thus far generated by an interruption of a magnetic flux caused with the rotation of the rotating shaft. This eliminates changes in inductance of coils 22a-22d and also in a drive current at the drive circuit 23. This change in conduction is detected with a current change detection circuit 24 and converted into an ON-OFF signal to make a switching signal. This allows the replacement of the switching means from the conventional contact type with a contactless type, thereby achieving higher reliability and durability of the apparatus.

Title: Rolling method for steel ingot
Inventor: ENDOU YOSHIYUKI
IPC: B21B1/02
Filed: 1980-05-06
Abstract: PURPOSE:To reduce the amount of crops, and to improve the yield, by carrying out a step-forming rolling pass before a broadside rolling pass. CONSTITUTION:A skew broadside rolling is pass applied to a steel ingot 5 with a rolling reduction on the bottom 7 side larger than that on the top 6 side. Hereby, the breadth of the bottom 7 becomes larger than that of the top 6. During this skew broadside rolling pass, an upper work roll is inclined correspondingly to the variation in the thickness of the ingot. A longitudinal rolling pass is then applied to the ingot in order to elongate it to a certain length. Although the thickness becomes uniform as a result of said longitudinal rolling pass, the breadth of the bottom is kept as larger than that of the top as it is before the longitudinal rolling pass. A step-forming rolling pass is then applied to the ingot in the longitudinal direction so as to provide the ingot with a three-staged thickness distribution. Then, a broadside rolling pass is applied to the ingot which is thereby formed into an almost rectangular plate. Finally, a longitudinal rolling pass is applied to the plate which is hereby formed into a product having a required thickness and length; thereby, a rectangular plate 8 is manufactured.

Title: Reel shaft driving device
Inventor: AOI TAKAHISA
IPC: B65H23/06
Filed: 1982-04-08
Abstract: PURPOSE:To simplify the structure to make it small-sized and to apply a back tension properly, by releasing the friction mechanism of a take-up reel in accordance with the direction of tape running and operating always only the friction mechanism of a supply reel. CONSTITUTION:An idler 2 is set on a turning plate 3 which is attached freely rotatably around a fulcrum 6. The turning plate 3 is floated in the direction of an arrow 5 by the rotation frictional force between the idler 2 and an idler bearing 4, and the rotation of a driving wheel 1 is transmitted to turn a reel shaft 7 in the direction of an arrow 26 by contact and rotation of a reel base 8 having the reel shaft 7 and the idler 2. If the driving wheel 1 is rotated in the direction opposite to the direction of an arrow 11, the rotation of the driving wheel 1 is transmitted to the idler 2, and the turning plate 3 is floated in the direction opposite to the direction of the arrow 5, and a reel base 10 having a reel shaft 9 and the idler 2 are brought into contact with each other and are rotated, and therefore, the rotation of the driving wheel 1 is transmitted to turn the reel shaft 9 in the direction of an arrow 27. Since the reel shaft driving system and a back tension function are independent of each other completely when a tape is run, tape running is stabilized for normal-speed tape running and high-speed tape running, and the strength of the back tension is controlled independently.
