IPC: B29L7/00
Filed: 1987-07-20
Abstract: PURPOSE:To obtain a film, which has uniform molecular orientation and high dimensional stability by a method wherein the longitudinal shrinkage is preceded by the shrinkage in biaxial directions. CONSTITUTION:In a heat treatment zone F, the elimination of internal strain due to stretching and the control of degree of crystallization are done. In the heat treatment zone F, a shrinking zone J and a cooling zone K are provided. In the shrinking zone J, the width Y of a sheet-like material is gradually narrowed to the width Z and at the same time the pitch Pmax of clips 2 is guided by being controlled with guides 4, 5 and 6 so as to bend roller chains 19, resulting in turning the pitch of the clip 2 into Pi and also longitudinally shrinking the sheet-like material or shrinking simultaneously longitudinally and laterally. As a result, a highly functional film, in which the molecular orientations in longitudinal direction and in lateral direction of a sheet-like material are well balanced, can be manufactured.

Title: Cutting amount detecting method and device
Inventor: MAEDA YUKIO
IPC: B24B49/12
Filed: 1981-11-10
Abstract: PURPOSE:To control the cutting amount by irradiating a proper width of light beam from a light emitting section then detecting the width of the light beam blocked by a grindstone, material to be grinded, etc. CONSTITUTION:The light emitted from a light source 7-1 is made into a parallel light beam having proper width in Z-direction through a lens thus to irradiate a detector B8. A work chuck 3 is grinded by a grindstone 1 to finish the surface. At this position a counter 17 for a linear scale 13 is reset. When the grindstone 1 lowers to block the parallel light beam, an accumulator 21 will produce the output SIGMAVR to lower the rotation of a drive motor 11 and to change the lowering speed of the grindstone into the ginding speed. When the grindstone lowers further to reach to the referential position L2 thus to produce the output SIGMAV0 from the accumulator 21, the lowering of the grindstone is stopped. Consequently the air-cut time can be shortened.

Title: Reproducing stylus and its production
Inventor: KATO TOSHIRO
IPC: G11B3/46
Filed: 1985-08-14
Abstract: PURPOSE:To join a grip and a front end member without an alloy solder material by joining a front end member 3 consisting of diamond or the like to the front end part of a grip 1 consisting of titanium or its alloy through a joining part 6a consisting of titanium. CONSTITUTION:After grips 1 and a joining film 6 of the front end member are so adjusted that they are held between the plus electrode and the minus electrode of a DC spot welding machine 7 and are brought into contact with each other by 200g pressure, 4,700A peak current is flowed between grips 1 and the joining film 6 of the front end member 3 with power of 30W.sec for 1.8msec. Titanium of the joining film 6 of the front end member 3 and titanium or its alloy of grips 1 are melted into one body and the front end member 3 is buried in grips 1; and in case of a stylus for records, the joined part of grips 1 is ground into a conical shape to expose the front end member 3 consisting of diamond from grips 1 and the joining part 6a. Titanium of the joining part 6a of the reproducing stylus formed in this manner is not distinguished from titanium or its alloy of grips 1, and there is not a fear of corrosion and elution. Thus, normal titanium welding is possible, and welding in vacuum is unnecessary to make an expensive vacuum welding equipment unnecessary.

Title: Video disk
Inventor: TORII KENICHI
IPC: G11B23/36
Filed: 1983-09-29
Abstract: PURPOSE:To improve deterioration of a picture quality caused by a crosstalk, by making a track pitch of a field signal of the same frame narrower than a track pitch of a field signal of a different kind frame, and executing a recording. CONSTITUTION:In the n-th frame, recording is executed so that a track pitch d1 by which signals of Fn,o and Fn,e are recorded, and the n-th and the (n)+1-th field signals, namely, a track pitch d2 of Fn,3 and Fn+1,o become d1<d2. As a result, when a read beam spot 7 is scanning an Fn+1,e field of the (n)+1-th frame, the beam 7 comes near to the adjacent signal Fn+1,o, too, and a crosstalk occurs, but the Fn+1,o signal and the Fn+1,e signal in the same frame have a high correlation as a picture signal, therefore, a large interference is not given. On the other hand, no interference signal enters by applying a tracking servo so that the beam 7 does not contact with an Fn+2,o signal of the (n)+ 2-th frame of the adjacent track.

Abstract: PROBLEM TO BE SOLVED: To freely adjust the angle of a shelf plate by attaching a spline socket and a spline boss to a side plate or shelf plate side, fitting the boss to a spline hole and supporting the shelf plate. SOLUTION: The spline socket 10 is fixed in the state of being fitted to a recessed part formed on a side face to the side plate 9, one shelf plate 8 is fitted to a U-shaped side frame and the spline boss 11 is attached to the side frame 12. Then, the spline boss 11 is fitted to the spline hole of the spline socket 10 to support the shelf plate 8 and the inclination of the shelf plate 8 is appropriately set by rotating the spline boss 11. In the case of adjusting the inclination of the shelf plate 8, a fixing pin 13 is pulled out of the side frame 12 and the shelf plate 8 is detached from the side frame 12. Thus, the spline boss 11 is separated from the spline socket 10 along with the side frame 12, rotated in an optional direction and fitted to the spline hole of the spline socket 10 again.  By attaching the shelf plate 8 to the side frame 12 and fitting the fixing pin 13, the shelf plate 8 is turned to a prescribed inclination angle.

Title: Connecting structure for circuit board
Inventor: MIYAKE TOSHIHIRO
IPC: H05K1/14
Filed: 1994-07-07
Abstract: PURPOSE:To provide a connecting structure for circuit board in which any solder bridge can be suppressed to permit fine processing and the inspection after connecting can be simplified. CONSTITUTION:A width of a first connecting land 6 on a circuit board 2 is larger than that of a second connecting land 5 under a flexible board 1 and the land 5 is included in the widthwise area of the land 6, so, even when the lands 5 and 6 are bonded with each other by soldering, a solder 3 does not jut out an adjacent connecting land area and it spreads toward the first connecting land from the second connecting land, forming a solder fillet 4. Since the fillet 4 is formed securely, the generation of solder bridge can be prevented and the wiring interval can be made smaller. Further, since the formed fillet 4 can be observed visually from the side of the transparent flexible board 1, the inspection after soldering can be performed easily, so that defective products may be hardly shipped.
