Title: Injection molds
Inventor: HARUNA SHUNICHI
IPC: B22D17/22
Filed: 1993-10-05
Abstract: PURPOSE:To obtain an excellent molding result even when a core largely protrudes from a stationary mold by providing a slide block for molding a sidewall of a molded form and a core for molding a cavity in the form together in a stationary mold. CONSTITUTION:A stationary mold 10 is formed of a supporting plate 11, and a stationary mold body 12 separable to a predetermined distance from the plate 11. A stationary side core 20 for molding a cavity in a molded form 1 is formed in the body 12. A slide block 21 energizes a compression coiled spring 23 in a direction for protruding from the body 12 and for releasing from the form 1. The body 12 and a movable mold 30 are held in a close contact state at a stage of removing the core 20 from the form 1, then converted to an unlocked state so that the mold 30 is separable from the body 12.

Title: Portable compressor
Inventor: SUZUURA TSUKASA
IPC: F04B41/02
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To reduce the number of part items and the man-hours by forming a guide passage for guiding the cooling air to be sucked and discharged by a fan with the inner wall of a cover, a motor, a compressing part or the outer peripheral wall of an air tank. SOLUTION: A compressor main body is covered with a cover 1 over the nearly whole thereof so as to insulate the noise and so as to prevent the exposure of a high temperature part. Cooling air 5 is led into a motor housing 8 through a cooling air inlet 9 by the rotation of a fan, and after cooling the motor, the cooling air is discharged from a cooling air discharge port 4. Furthermore, the cooling air 5 is guided by the cooling air guide passage formed by the inner wall of an upper part of the cover 1, a rib 3 provided so as to reinforce the cover 1, a motor arranged inside of the cover 1, a compressor and the outer peripheral wall of an upper part of an air tank 7. Since the guide passage is formed, the cooling air 5 can be efficiently guided without adding a new parts, and the number of part items and the man-hours can be reduced.

Title: Developing method
Inventor: HANEDA SATORU
IPC: G03G15/09
Filed: 1983-12-28
Abstract: PURPOSE:To improve an image quality by constituting a developer consisting of a toner particle and a carrier particle so that said toner particle does not contain a particle whose particle diameter is below a prescribed value of an average particle diameter of a toner particle. CONSTITUTION:When a development of an electrostatic image of an image carrying body 1 is executed, a magnetic brush formed on the surface of a sleeve 2 vibrates and moves on the sleeve 2 because a magnetic flux density of its surface as the sleeve 2 or a magnet body 3 rotates, and in that case, a uniform development is executed to the surface of the image carrying body 1. In this case, a developer D consisting mainly of a carrier particle and a toner particle is used so that said toner particle does not contain substantially a particle whose particle diameter is below 1/4 of an average particle diameter of a toner particle. By using such a developer D, a recording picture having a high definition can be obtained without dropping a picture quality.

Title: Resin roller
Inventor: SUZUKI MOTOI
IPC: B29K23/00
Filed: 1994-10-14
Abstract: PURPOSE: To provide an inexpensive resin roller having excellent chemical resistance. CONSTITUTION: The resin roller 10 having a shaft 14 projecting from the roller main body 12 consists of a roller base body 16 joined with an axial end member 26 having chemical resistance. The roller base body 16 is covered with an olefin elastomer resin coating layer 18. The roller base body is obtd. by cutting a resin pipe into a specified length which is produced by injection molding of a thermoplastic resin. In this body, plural ribs 22 to reinforce the body are formed in a radial state in the cylindrical outer part 20 in one body. The axial end members are joined under pressure to the ends of the roller base body 16 thus formed, and then an adhesive is applied to form an adhesive layer on the surface of the base body 16. Then the resin coating layer is formed by injection molding to wrap the body.  Since no metal is used in the inside of the resin roller main body 12 but the roller body is produced by molding a resin, corrosion of the roller base body 16 due to permeation of chemicals is not caused.

Title: Production of unidirectionally stretchable composite nonwoven fabric
Inventor: NOGUCHI NOBUO
IPC: D04H5/08
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing composite nonwoven fabric having excellent stretchability. SOLUTION: At first, a unidirectionally stretchable nonwoven fabric which is stretchable selectively in the lateral direction is prepared. A concrete example of the nonwoven fabric can be a nonwoven fabric constituted with a group of long fibers, having heat fused zones where the long fibers are fused to each other with intervals, and arranging the long fibers substantially in the longitudinal direction outside the heat fused zone. The unidirectionally stretchable nonwoven fabric is hardly stretchable in the direction of arrangement of the long fibers, i.e., in the longitudinal direction, and it has good stretchability in the direction perpendicular to the above direction, i.e., in the lateral direction. On the other hand, fiber web containing short fibers having latent crimping property is also prepared.  This fiber web is laminated with the unidirectionally stretchable nonwoven fabric in such a state that the unidirectionally stretchable nonwoven fabric is widened in the lateral direction, to obtain a laminate. Further, the laminate is subjected to an interlacing treatment while keeping the widened state. Subsequently, the widened state is released to allow the short fibers having latent crimping property to express crimps.
