Abstract: A data file encryption transmission/reception system includes a computer with a registration module that encrypts input data files. The registration module includes a string conversion module that configured to convert the data file to be encrypted to string data, a key generation module that configured to generate a common key, and to divide the common key and the string data into first input information and second input information, a common key encryption module is configured to encrypt the first input information with the common key, to thereby generate common key encrypted data, a searchable encryption module that configured to encrypt the second input information in accordance with searchable encryption with a user secret key set in advance, to thereby generate searchable encrypted data and a communication module is configured to register a set of the common key encrypted data and the searchable encrypted data in the data management server.

Abstract: A tire manufacturing method to obtain a base tire superior in uniformity when the base tire has a cushion gum applied thereon. In this process of tire manufacture, the thickness from a belt, which is located in the outermost layer of the base tire having an application surface for the cushion gum, to the application surface is measured along the circumference of the base tire so as to detect a maximum thickness position. Then the circumferential winding of the cushion gum extruded from an extrusion molding unit is started from the maximum thickness position.

Abstract: Plastically deformable support bodies (16) are embedded in a gel-like elastic body (15). A bottom-surface adhesive layer (15b) of the gel-like elastic body (15) is bonded to a floor surface (F), and a pressurizing plate (13) is kept on a top-surface adhesive layer (15a). A leg section (2) of equipment (1) is restrained from moving laterally with a bolt (22) provided on the pressurizing plate (13). A load of the equipment (1) is used to apply pressure to a vibration-damping pad (12) via the pressurizing plate (13). A restraint wall (18) is disposed around the vibration-damping pad (12) and a caulking compound (20) is packed in the opening between the pressurizing plate (13) and the floor surface (F). The caulking compound (20) is blocked by the restraint wall (18), and the gel-like elastic body (15) is allowed to deform due to a gap (19) formed between the restraint wall (18) and the vibration-damping pad (12).

Abstract: [Problem] To prevent, using a simple seismic isolation structure, vibration, noise, and toppling of a heavy object installed on a floor surface where anchor bolts cannot be used. [Solution] In a seismic isolation structure 11 for a machine 1, plastically deformable support bodies 16 are embedded in a gel-like elastic body 15 of a vibration-damping pad 12. A bottom-surface adhesive layer of the gel-like elastic body 15 is bonded to the floor surface, and a pressurizing plate 13 is bonded to a top-surface adhesive layer of the gel-like elastic body 15. The pressurizing plate 13 bears weight of the machine 1 and uniformly applies pressure to the entire vibration-damping pad 12. The base 21 of a holder 14 is welded to the upper surface of the pressurizing plate 13; a bolt 22 erected on the base 21 is caused to penetrate a through-hole 3 of a leg section 2; and the leg section 2 is restrained on the pressurizing plate 13 by the holder 14 from moving laterally.

Abstract: [Problem] To provide a chip resistor and a method for manufacturing thereof, the chip resistor keeping easily soldering strength even if mounted in a horizontal position, and never projects from a holding recess of a positioning jig in a mounting process, and further does not hinder miniaturization thereof from being promoted, while keeping a good appearance thereof. [Means of Solution] In manufacturing a chip resistor 10, front-face electrodes 12 and resisters 13 are formed on the front face 20a of a large size substrate 20, and rear-face electrodes 16 are formed on the rear face 20b of the large size substrate 20. When the rear-face electrodes are formed, the rear-face electrodes 16 are extended to inclined faces of V-shaped grooves of second dividing grooves 22 on the rear face 20b and these extended parts are made to be side-face electrodes 16a.

Abstract: The uneven wear produced in the tread side rib in the heavy duty pneumatic radial tire is prevented by arranging a peripheral fine groove on a particular region of the side face of the tread portion in a particular form.
