Abstract: PURPOSE:To eliminate clogging by a carrier and obstruction of gas ejection and improve the gas adsorption performance of the carrier and charging performance by making the carrier which consists of a powder-like substance of vermiculite filled in a cylinder carry the inflammable liquefied gas. CONSTITUTION:In a cylinder for charging inflammable liquefied gas, the inflammable liquefied gas such as the liquefied propane and the liquefied butane gas is filled into a pressure vessel.

Abstract: PROBLEM TO BE SOLVED: To eliminate the blurring and the distortion of an image and to enhance the quality of the finished image and durability by forming a light- transmissive substrate of cross-linked polymer resin and specifying the double refraction of the light-transmissive substrate and difference in the substrate. SOLUTION: The light-transmissive substrate for an electrophotographic photoreceptor is formed of the cross-linked polymer resin and constituted so that the double refraction thereof is <=150 nm and the difference in the substrate is within 50 nm. That means, the optical uniformity of the substrate itself is required and it is good that the double refraction is low and the difference caused according to the parts of the substrate is small. The regulated double refraction can be measured by a well-known method using an equipment such as an Abbe's refractometer, a strain gage or an ellipsometer. It is good that the double refraction is measured so that the maximum and the minimum characteristics out of the characteristic of the whole parts of the substrate of the photoreceptor can be recognized.

Title: Floating head slider
Inventor: INUMOCHI MITSUO
IPC: G11B5/60
Filed: 1981-06-04
Abstract: PURPOSE:To prevent a disk from being flawed, by forming grooves having prescribed depth and width, respectively, extended in the lengthwise direction of a pair of floading surfaces, on these floating surfaces formed by extending in the flow direction of air in accordance with a magnetic medium. CONSTITUTION:On floating surfaces 2a, 2b of a head slider, grooves 22a, 22b are formed, respectively. As a result, lateral leakage of an air flow is increased, floating force is not generated in the part of these grooves 22a, 22b, and on only the split floating surface, the floating force is generated. Since the floating force is varied by cube of width dimensions of the floating surface, the floating  force generated on the floating surface is reduced remarkably, and the extent of  floating can also be reduced remarkably. In this way, it is possible to obtain a  high performance product which has reduced head crush in case of start and  stop, and is suitable for high density recording.

Abstract: PURPOSE:To improve impact resistance with simple constitution by using a flexible substrate which is molded expandably and contractably for connection of electrode terminals for external connection of a liquid crystal panel and a driving circuit board and using this flexible substrate as a supporting body of liquid crystal panel. CONSTITUTION:The liquid crystal panel is electrically connected to the circuit board by adhering the flexible substrate 6 via an anisotropic conductive adhesive agent to the electrode terminals and is supported apart a specified distance from a supporting structural member 9. The flexible substrate 6 is formed by laminating copper foil 11, etc., on, for example, a base material 10 of a polyimide film, and etching the copper foil to a prescribed pattern shape, then pressing the material to a waveform exclusive of the end parts necessary for connection and is expandable and contractable. Accelerations are, therefore, absorbed in the connecting member even if the stress in the normal direction of the surface is generated in the panel. The impact resistance is improved in this way with the simple constitution.

Title: Spin welding member
Inventor: SHIBAYAMA TERUTSUGU
IPC: B29C65/06
Filed: 1987-04-08
Abstract: PURPOSE:To contrive efficiently a welding operation by eliminating processing treatment after welding by making a mounting space small, by making a fitting part of a spin welding member fitting to a spin welding machine into a specified small form. CONSTITUTION:A recessed part 14 of a flange part 12 of a spin welding member 11 is fitted to a fitting protrusion 18a of the tip part of a fitting member 18 of the spin welding machine 16, (a fitting part of the recessed part 14 provided on the flange part 12 is designed so that the fitting part does not protrude outward in the radial direction from the fringe part of the flange part 12). When the fitting member 18 is turned at a high speed, the spin welding member 11 also is turned at a high speed. Therefore, a contacting surface is melted through spin frictional heat between a plane A of a base plate 15 and the back of the flange part 12, and both become a state where they are stuck to each other. When a spin is suspended, resin melted and stuck is solidified through cooling and welding of the back of the flange part 12 of the spin welding member 11 to the plane A of the plate 15 is performed. As the fitting part does not protrude outward of the flange, a small mounting space suffice, and cutting of a protrusion becomes unnecessary.

Abstract: PURPOSE:To prevent occurrence of misalignment in a winding side edge and a difference of density, in a surface winder for papers, by turning a winding roll in a slide contacting state to a drum roll, mounting a roller to a shaft of said winding roll and forming an elastic cushion member to the upper usrface of a supporting rail for said roller. CONSTITUTION:A drum roll 1 is rotated in the direction of an arrow head to wind a sheet material A on a cylindrical pipe and form a sheet roll B, and the sheet roll B is always slidably contacted to the drum roll 1 by the action of empty weight of the roll B and a slope 4a of a rail 4, and turned to smoothly perform winding work. In accordance with the progress of winding, the empty weight of the sheet roll B, radial sheet thickness, etc. cause change or unequality, even if the roll B tends to move sideward, tilt and so on, sideward movement and tilting of a roller 9 can be suppressed by friction force and vibro-absorption of a cushion 5 on an upper surface of the rail 4. Accordingly, sideward misalignment of winding and occurrence of density difference can be prevented.
