Abstract: PURPOSE:To regulate the damping force optionally on respective sides of extending and pushing by providing inner and outer leaf valves partly overlapped in inner and outer rims for constructing a floating-valve type valve device provided in the piston part of an oil-pressure damper. CONSTITUTION:An annular inner leaf valve 13 is arranged on the outer circumference of a plurality of axial oil grooves 12 grooved on one side of an oil passage 11 of a piston 10 provided on one end of a piston rod 16 of an oil-pressure damper. An annular outer leaf valve 15 is arranged to be supported by an annular outer seat face 14 on the periphery of the piston 10 on its outer circumference, and the under side of the outer circumference of the inner leaf valve 13 is overlapped on the upper side of the inner rim of the outer leaf valve 15.

Title: Focus detector
Inventor: SUDA YASUO
IPC: G03B3/00
Filed: 1986-03-06
Abstract: PURPOSE:To uniformize the focusing state on a light reception face and to detect the focus with high precision by providing a transmissive optical member in the same position as a predeterminate image forming surface in a focus detector of the image deviation system. CONSTITUTION:An optical member 2 like an infrared filter or a protective glass is arranged near the predeterminate image forming surface corresponding to a film surface so that the object-side face of the optical member 2 coincides approximately with the predeterminate image forming surface. Obstacles stuck to the optical member 2 are allowed to have equal influences upon two light receiving element arrays 8-1 and 8-2 to equalize approximately the phase difference due to obstacles to that of the image of the object formed by a photographic lens, and the error is reduced. Since the optical member is arranged near the primary image forming surface equivalent to a photosensitive face in this manner, the phase difference due to the image of dust is equalized to that of the image of the object formed by the photographic lens when the image of dust stuck to the optical member is projected on two light receiving element arrays, and the focus is detected with a high precision.

IPC: F16K5/22
Filed: 1982-03-26
Abstract: PURPOSE:To provide a simple structure for a rotary valve, which is capable of preventing acting of unbalanced forces to a closer of a rotary valve when a lubricating medium is charged in the valve, by forming an opening in the closer, and also forming a recess having the same shape as the projected configuration of the opening in the peripheral surface of the closer at the diametrically opposed position. CONSTITUTION:A closer 2, formed with a fluid passage 1 obtained by connecting a plurality of fluid passage sections shaped in the form of an L-shape or a T-shape having streamlines inclined to each other, is fitted in a valve body 3 in a freely rotatable manner. An circumferential opening 1A of the fluid passage 1 is formed in the outer surface of the closer 2 and a recess 4 having the same or a substantially equal shape as the projected configuration of the opening 1A is also formed in the outer surface of the closer 2 at the diametrically opposed position. Therefore, when a lubricating medium is charged under high pressure into a small clearance between the outer surface of the closer 2 and the inner surface of the valve body 3, the charging pressure is balanced at any diametrically opposed positions of the closer 2 over the entire circumference of the same, so that it is enabled to prevent acting of unbalanced forces to the closer.

IPC: G11B5/127
Filed: 1983-03-23
Abstract: PURPOSE:To prevent the deformation of a main core owing to sliding of a magnetic tape by forming with tight adhesion thin films of a nonmagnetic material on the surface of a main core which is opposite to auxiliary cores so that the gap part of the main core is covered with the thin film. CONSTITUTION:Thin films 7 and 8 of a nonmagnetic material are formed on the surface of a main core which is opposite to auxiliary cores 2 and 3 by a sputtering or vacuum vapor deposition process. Then these cores 1-3 are bonded to each other to obtain a magnetic head. No gap is produced between the core 1 and films 7 and 8 although gaps 10 are produded between cores 2/3 and films 7/8 since the films 7 and 8 cover the gap of the core 1. This head can prevent the deformation of the core due to sliding of a magnetic tape and then prevent the deterioration of reproduction efficiency.

Filed: 1993-02-16
Abstract: PURPOSE:To eliminate the need for performing horizontal curing in constructing a steel deck floor board by using a major floor panel. CONSTITUTION:Steel decks 11 are arranged and laid on beams 2 and secured thereto. Steel decks 12 at both right and left end portions of each beam 2 are upwardly rotatably connected to the fixed steel decks 11 by means of hinges 13. This major floor panel 10 is assembled on the ground. The major floor panel 10 is hoisted to a floor for construction using a crane and assembled. In that case, the steel decks 12 at both ends are opened. The steel decks 12 at both ends are therefore not blocked by right and left girders 4. The work of joining both ends of each beam 2 to the girders 4 is carried out from a space 15 between the steel decks 12 and the girders 4, which is formed when the steel decks 12 at both ends are opened. After this junction is finished the steel decks 12 at both ends are closed. Because there is no space when the steel decks are closed, humans and articles are in no danger of falling and so horizontal curing that requires stretching of a net below, etc., can be omitted and the safety of work can be increased.
