Patent JP-H02261995-A (JP)
Title: Pipe fitting
Inventor: YOKOMATSU TAKAHIRO
IPC: F16L37/50
Filed: 1989-03-30
Abstract: PURPOSE:To enhance the piping work efficiency by furnishing a pipe fitting inside it with a core slidable in the axial direction, a sleeve having a slope, and a collet which contacts this slope and whose dia. can be enlarged or shrunk, and equipping this collet with a boss having a sharp edge and a flat top surface. CONSTITUTION:When a hose 35 is inserted from the major dia. 22b side of a pipe fitting concerned, the hose end 35b widens the end 28e of a collet 28 and contacts a flange part 24a. Because this collet 28 is equipped with No.1 ring-shaped boss 31, the hose 35 is detained with a sharp edge 31a through the action of the restoring force of collet 28. Therefore, the hose 35 is prevented from slipping off. As the collet 28 has also No.2 ring-shaped bass 33, application of a fluid pressure moves a core 24 to the right, and the outside surface 28a of the collet 28 contacts a slope 26a of a sleeve 26 to cause diametric shrinkage of the collet 28, and thus the hose 35 is tightened. Because the top surface of the inner circumference of boss 33 is wide, the hose 35 will never be damaged. This facilitates the tightening works.

Title: Mold for integral molding of plate glass and synthetic resin
Inventor: SHIMADA NORISHIGE
IPC: B29C45/14
Filed: 1986-04-08
Abstract: PURPOSE:To absorb dimensional deviation of a plate glass and to prevent the plate glass from breakage when a mold is clamped, by providing both a concave space holding the plate glass in an inner circumferential surface of a fixed mold and a floating core fitting in a pocket hole formed in an inner circumferential surface of a movable mold and being acted by means of a spring. CONSTITUTION:A floating core 8 tightly adhered with a plate glass is pushed to the right hand side by means of a tightly adhering force, by which a spring 12 is contracted and the floating core 8 is moved to the left hand side by the repulsing force of the spring. In this case, as dimensional deviation of the plate glass 4 exceeds + or -1.5mm, the tightly adhering force changes with the change of the plate glass 4, but floating core 8 is reacted by means of the pushing force of the spring 12 against this change to adhere tightly and uniformly with the plate glass 4. Under this state, a resin material is injected in a cavity 6 around the plate glass to adhere tightly the circumferential part of the plate glass 4 with the resin material and to adhere tightly the both surfaces of the plate glass with the holding part of the mold 1 and the floating core 8. A monolithic molding of a glass having an accurate curvature and a resin can be thereby prepared.

Abstract: PURPOSE:To prevent positional deviation of an outer layer material and an inner layer material by opening a laminated board for the inner layer material according to the shrinkage factor of a special range, and heat-pressure-molding it together with prepreg and the outer layer material. CONSTITUTION:A laminated board for an inner layer material is opened in a position according to shrinkage factor of 0.01-0.1% at the time of secondary molding. That is, if it is opened with less than 0.01% of the factor, a deviation easily occurs, while if it exceeds 0.1% of the factor, the deviation also easily occurs. Inner layer materials for BVH, IVH are used as the laminated board for the inner layer material, and those of landless specification are particularly effective and preferable. As the heat pressure molding, a press, a vacuum press, a double-belt molding machine, etc., can be employed, but not particularly limited. As resin used for the laminated board for the inner layer material, the prepreg, and the outer layer material, general resins such as, epoxy resin, phenol resin or fluorine resin alone, or their modified materials, or their mixture can be used.

Filed: 1993-03-17
Abstract: PURPOSE:To perform the phase detection of the rotor and the stator of a motor surely by supporting yoke plates made out of magnetic material at parts facing phase detecting permanent magnets on the inner surface of the motor case, and arranging Hall elements between these yoke plates and the phase detecting permanent magnets. CONSTITUTION:Yoke plates 15 made out of magnetic material are fixed to parts facing phase detecting permanent magnets (DM) 11, on the inner surface 4a of a rear lid 4 constituting a motor case 1. Hall elements 12 are supported at parts facing the DMs 11 on single-side surfaces of the yoke plates 15. Concerning to the yoke plates 15 and the Hall elements 12, they are provided at a plurality of spots in the circumferential direction. Namely, magnetic flux from the DMs 11 returns back to the DMs 11 immediately after passing the yoke plates 15, since the yoke plates 15 are fixed to the inner surface 4a. Accordingly, the air gap parts in the magnetic circuit become shorter. As the result of this, the density of magnetic flux passing each Hall element 12 becomes higher, and the detection of the direction of the magnetic flux by the Hall elements 12 can be performed surely.

Title: Encoder
Inventor: TAMAKI HIROSHI
IPC: G01D5/347
Filed: 1980-06-17
Abstract: PURPOSE:To eliminate the need for a complicated process circuit and to enable to obtain a high resolution through the employment of an inner insertion method, by a method wherein a device is located so that a pitch of a light and dark pattern of a code plate is different from a pitch of a group of a group of linear sensors. CONSTITUTION:A light from a light source 3 illuminates a light and dark pattern of a code plate 1, and the light and dark pattern is projected onto a linear sensor 2. In this case, the pitch of the light and dark pattern is caused to slightly differ from a pitch of a group of sensors 2. The output of the sensor 2 generated resulting from the movement of a plate 1 is amplified (6) and is inputted to a signal distributor 8. The distributor 8 outputs a component of, for example, an element A to an SA terminal and an output of an element C to an SC terminal, and input them to envelope curve detectors 9 and 10, respectively. The outputs of the detectors 9 and 10 are compared with each other by means of coincidence pulse generator 11, and when the detectors 9 and 10 equalize in the outputs, a pulse is sent to stop counting of a counter 12. This causes the repeating change of the counting value of the counter 12 in proportion to the movement distance of the plate 1 and obtains resolution of an internal insertion due to a difference between the pattern of the plate 1 and the sensor 2.
