Title: Breaker for wiring
Inventor: MATSUOKA YUKIHIRO
IPC: H01H71/16
Filed: 1991-12-13
Abstract: PURPOSE:To provide a breaker wherein damping of force, acting on a movable plate from a cradle in a direction of separating a movable contact from a fixed contact, is reduced to surely open the contact. CONSTITUTION:When an abnormal current passes through a main wiring of inserting a movable contact 4a and a fixed contact, a cradle 6 is rotated with a cradle shaft 6a serving as the center by force of an inverting spring. A movable plate 4 of holding the movable contact 4a separates the movable contact 4a from the fixed contact by receiving impact force and pressing force from an end part of the cradle 6 at the time of its rotation. The movable plate 4 is provided with a steelmade movable main plate 21 and a copper-made contact holding plate 22 of holding the movable contact 4a. The movable main plate 21 and the contact holding plate 22 are secured by inserting a protrusive piece 21b, protrusively provided in the movable main plate 21, through the contact holding plate 22 to make plastic deformation. An end part of the cradle 6 is arranged so as to be opposed to a point end part of the protrusive piece 21b.

Title: Automatic focus adjustment device
Inventor: SUDA HIROSHI
IPC: G02B7/28
Filed: 1989-12-18
Abstract: PURPOSE:To prevent tentative production of unsharp by detecting an action of variable power from the wide mode to the telescope mode and increasing the loop gain by a specific value during the action of variable power so as to quicken the automatic focus adjustment thereby catching up with the correction of stop position. CONSTITUTION:Wobbling of an image pickup element 6, that is, the amplitude of vibration is increased by a prescribed value proportional to a zooming speed (a) at an image pickup element drive circuit 22. Thus, the amplitude of the optical path modulation component in the pickup signal outputted from the image pickup element 6 is increased. As a result, the closed loop gain of the focus control system extracting the signal component by the optical path modulation from the pickup signal is increased by the image pickup element 6. Thus, the detection sensitivity to defocus quantity is increased, an output level of a synchronizing detection circuit 12 is increased thereby driving a focus motor at a higher speed than a normal speed. Then in response to the zooming speed from the wide mode into the telescope mode, the position correction of a focus lens is quickened and production of unsharp during zooming is prevented.

IPC: G11B23/03
Filed: 1987-12-26
Abstract: PURPOSE:To prevent the edge part of a shutter from being folded and damaged by causing the abutting side of an operating pin in a channel for insertion, which is formed in a shutter side, to be larger than the channel for insertion, which is formed in a sliding body side, for the channel for operating pin insertion to be used for opening and closing the shutter. CONSTITUTION:In the fixing part of a shutter 4 and a sliding body 6, two channels 7 for insertion of the opening operation of the shutter 4 are formed in upper and lower directions. Then, the abutting side of an operating pin 8 for the opening operation of a channel 7b for insertion in the shutter 4 is formed larger than a channel 7b for insertion in the sliding body 6. Thus, since the operating pin 8 in a drive device is directly abutted to the channel 7a for insertion in the sliding body 6 and this is not abutted to the channel 7b for insertion in the shutter 4, the edge part of the channel 7b for insertion in the shutter 4, whose thickness is thin, can be prevented from being abutted to the operating pin 8 and damaged by being folded.

Title: Production process of gypsum board and gypsum board
Inventor: HANEDA JUNICHI
IPC: E04C2/04
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a production process of a gypsum board having sufficient strength and also to provide the gypsum board. SOLUTION: This production process comprises producing a gypsum board provided with a humidity control function by using siliceous shale as a component of a raw material slurry of a core material of the gypsum board, wherein: as the siliceous shale, a siliceous shale crushed material having adjusted grain size such that the amount of a crushed material fraction having 0.1-3 mm grain size is >=70% of the total amount of the crushed material, is mixed into a base stock (such as gypsum) of the raw material slurry; and also the amount of mixing water in the raw material slurry is adjusted to <=60% and by reducing the amount of mixing water as compared with that in a conventional process, the calcined gypsum content in the slurry is relatively increased.  Thus, even when the siliceous shale content in the slurry is increased, the ratio of the amount of calcined gypsum infiltrated into a pair of base paper sheets for the gypsum board is increased as compared with that in a conventional process. Accordingly, dihydrated gypsum is sufficiently interlocked with fibers of each of the gypsum board base paper sheets and the adhesion between the core material and each of the board base paper sheets can be improved. In addition, the problem of reduction in flowability of the slurry due to the reduction in amount of the mixing water can be solved by adjusting the grain size of the siliceous shale crushed material or using a superplasticizer.
