Patent JP-H01255792-A (JP)
Title: Flow divider
Inventor: NAKAYAMA KOICHI
IPC: F16L41/02
Filed: 1988-04-01
Abstract: PURPOSE:To prevent the possibility of crating formation due to the flow of raw material during extrusion molding by extruding the raw material nearly from the centerpart or outlet side pipe parts extended to both sides to form an inlet side pipe part, and providing a recess part for the raw material on the opposite side from the extruding part of the inlet side pipe part. CONSTITUTION:A flow divider 51 consists of an inlet side pipe part 52 for refrigerant and outlet side pipe parts 53a, 53b, and it is provided with a recess part 54 for raw material. In order to manufacture the flow divider 51, a lead rod 56 is inserted into a copper pipe 55, and the copper pipe is strongly pressed up and down by an upper die 57a and a lower die 57b, and the lead rod is clamped by hold-down jigs 61a, 61b. As a result, the copper pipe 55 and the lead rod 56 are extruded into a hole in the lower die 57b to form a pipe end 65 and complete a T-shaped pipe 66. In this instance, since the flow of the raw material is absorbed in an escape groove 59 to form the recess part 54, crating observed on the internal surface of conventional flow dividers does not occur.

Filed: 1993-04-08
Abstract: PURPOSE:To lighten the weight of a projector at large and also, cut down the cost. CONSTITUTION:A socket 4 in which the base 3 of a bulb 2 is screwed is accommodated in the body being made by molding a metallic plate such as an iron plate or the like into a bottomed tube by press. The socket 4 is attached to the interior of the body 1 so that it may move slightly in the axial direction of the body 1, and besides the socket 4 is energized to the side of the bottom at one end of the body 1 by a plate spring 15. A circular projection 9 is made at the opening of the other end, and a packing 13 is attached so as to wrap this projection 9, and the section 2a of the collar of the bulb 2 is stuck fast to the packing 13 when the base 3 of the bulb 2 is screwed in the socket 4. Since the body 1 of a projector is made by molding the metallic plate such as an iron plate or the like by press or the like, the weight can be reduced, and also the cost can be cut down.

Title: Method for cleaning substrate and manufacture of liquid crystal display substrate
Inventor: TAGUCHI EIJI
IPC: B08B3/08
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently and simply removing contaminants on the surface of a substrate. SOLUTION: The surface of a substrate 12 is cleaned using a cleaning solution containing a mixed solution of an aqueous alcohol solution and a basic substance (alkanolamine). Since the aqueous alcohol solution is used as the cleaning solution, water easily penetrates an uneven part such as micropores or a groove in the surface of the substrate 12 (the deterioration of the interfacial tension of water), and consequently, contaminants such as an organic matter or particles remaining in the fine uneven part are effectively removed. Coupled with the aqueous alcohol solution, the basic substance is used as the cleaning solution and the basic substance is absorbed into the contaminants (e.g. polymer such as an adhesive material), which in turn, are swollen to promote hydration and diffusion minimization. Thus the contaminants are dissolved in the aqueous alcohol solution.

Abstract: PURPOSE:To make it possible to use many kinds of first crystals by arranging the first crystal between an X-ray source and a sample, providing a first-crystal moving means and an X-ray-axis turning means, taking out the characteristics X rays, and projecting the X rays on the sample. CONSTITUTION:The X rays from an X-ray generating device 1 is diffracted through a first crystal 2 and made to be monochromatic light rays. The X rays are diffracted again with a sample 6. The intensity of the X rays is measured with a detector 7. During the measurement, a sample stage 4 is driven with a goniometer 3 and rotated by theta times at a specified time interval for every specified angle with a sample axis omegaas the center. Meanwhile, a detector arm 5 is driven with the goniometer 3 by the same way and rotated by 2theta times in the same direction as the sample stage 4 at an angle twice the that of the sample stage 4 with the sample axis omega as the center. At this time, the sample 6 is rotated by theta times like the stage 4. The X-ray detector 7 is also rotated by 2theta times like the arm 5. The well known X-ray diffraction graph is obtained by the rotation of the sample 6 and the detector 7 such as this. When another kinds is used for the first crystal, the arranged position is changed with crystal moving means such as a guide groove 14 and a protruding piece 15, and the detection is performed.

Title: Disk chucking device
Inventor: KAMEMURA TAKESHI
IPC: G11B17/028
Filed: 1990-03-29
Abstract: PURPOSE:To prevent slip of a disk without increasing the size and the magnetic attracting force of a turntable and a chuck pulley by applying multi-pole magnetization to both the turntable and the chuck pulley. CONSTITUTION:The poles N, S of a turntable 6 and the S, N poles of a chuck pulley 7 are respectively attracted at chucking of a disk. In this case, the magnetic attracting force caused between the turntable 6 and the chuck pulley 7 is comparatively large because the magnetic poles are alternately arranged even when the magnetic field strength of poles N, S is comparatively small. Moreover, if the turntable 6 and the chuck pulley 7 are going to be deviated in the direction of rotation, the pole N(S) of the turntable 6 and the pole S(N) of the chuck pulley 7 are attracted together and the pole N(S) of the turntable 6 and the pole N(S) of the chuck pulley 7 are repulsed with each other, then the deviation is regulated. Thus, slip of a disk is prevented without increasing the size and the magnetic attracting force of the turntable and the chuck pulley.
