Title: Dividing device
Inventor: IDE YOSHIHISA
IPC: B23Q16/06
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To enable rotation and sure positioning by interlocking a positioning mechanism composed of a positioning groove and a positioning notch with a rotational drive mechanism composed of a rotational roller and a claw for rotational operation through a link mechanism. SOLUTION: Because by moving a base 11, a guide groove 10 is moved together with it, an extreme end roller 8 positioned in the guide groove 10 is also simultaneously moved in the arrow mark B direction. When the extreme end roller 8 is moved, the extreme end roller 8 side of a link lever 7 is moved in the arrow mark B direction, and the other end side of the link lever 7 is moved in the arrow mark A direction. Because the holding part 5a of a positioning notch 5 is also moved in the direction of fitting the positioning notch 5 into a positioning groove 3, to be in the positioned state. Because the positioning notch 5 held in the C, D directions by a holding base 18 is firmly fitted in the positioning groove 3, even if force is applied to a rotary shaft 2, a turn table 1 can be prevented from rotating.

Filed: 1979-09-05
Abstract: PURPOSE: To permit the opening amount and timing of the scavenging port of a uniflow scavenging-type two-cycle engine to be controllable for obtaing a lower specific fuel consumption by providing a cylindrical scavenging control valve that reciprocates in the direction of the axis of the cylinder liner to open and close the scavenging port.  
     CONSTITUTION: A uniflow scavenging-type two-cycle engine has a scavenging port 21 in the lower part of a cylinder liner 20. The scavenging port 21 is opened or closed by a cylindrical scavenging control valve 30 reciprocating with a crankshaft of the engine. In other words, opening or closing of the scavenging port 21 is not directly related to the reciprocation of a piston 10, but performed by the control valve 30 reciprocated by the driving system or the like linked with the crankshaft. Said mechanism permits the opening timing of the scavenging port 21 to be retarded as well as its opening time to be lengthened and its opening area to be enlarged, so that an engine having a lower specific fuel consumption is obtained.

IPC: H01J9/14
Filed: 1987-05-08
Abstract: PURPOSE:To form an oxide coated film at a relatively low temp. in a short time by discharging a part of the hydrogen generated by an oxidation reaction to the outside of a furnace in the title surface treatment of an electrical part. CONSTITUTION:A flat mask formed with an Ni-Fe material is annealed, straightened, and then press-formed into a spherical shape. The contaminant deposited on the formed shadow mask 6 is removed by degreasing and washing, and the mask 6 is set on a jig 5 in a furnace. Steam is then supplied into the furnace through a conduit 3, and the inside is filled with the steam atmosphere at a specified pressure. The hydrogen generated by the reaction of steam with the Ni-Fe material is discharged along with the steam in the furnace from an exhaust port 7 to the outside of the furnace, and fresh steam is successively sent into the oxidizing atmosphere in the furnace from the conduit 3. As a result, the black rust having specified emissivity can be formed on the surface of the Ni-Fe material by keeping the temp. of the furnace atmosphere at a specified temp. for a specified time.

Title: Manufacture of metal tube for bicycle
Inventor: JAMES L EASTON
IPC: A63B59/51
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To use a metal tube for a seat post of an off-road or all-terrein bicycle for improving riding comfortableness with a long post and a small frame by expanding a core to engage to the metal tube inside under sufficient heat and pressure for curing and bonding the core to the tube. SOLUTION: A built-up body comprising an aluminum tube 12 and an entire extended sleeve 26 is thermoset by increasing the temperature. During a setting cycle, the air pressure is maintained in a bag for maintaining appropriate tension. During thermosetting, the tube 12 is slightly expanded by increasing temperature, which enables extending of the sleeve 12. After the setting cycle, the tube 12 is shrinking as the built-up body cools, however the set sleeve 26 is not shrunk. Because the thermal expansion coefficient of the aluminum tube 12 is considerably higher than that of carbon fiber of the sleeve 12. Therefore, the cooling tube 12 is shrunk on the thermoset sleeve 26, which generates considerable compression.

IPC: B65H23/32
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent the photographic printing paper from being folded at its central part by providing a pressure roller with a small diameter part at its roller axial direction end side with respect to a pressure contact part capable of pressing the photographic printing paper held by a driving roller. SOLUTION: In the operating condition for conveying the photographic printing paper, the photographic printing paper is held between a pressure contact part 14A and a driving surface part 13A to be pressed and contacted therewith. On this occasion, an axial side end part 2a of the photographic printing paper is folded toward a small diameter part 14B. The small diameter part 14B is provided with a diameter smaller than the pressure contact part 14A so that the side end part 2a is not contacted with the small diameter part 14B even by the folding. By providing the difference in diameters, the wrinkling caused by the pressure contact of the end part 2a with the small diameter part 14B can be prevented even when the width side end part 2a of the photographic printing paper is folded.  Thus, a central part in the width direction of the photographic printing paper can be prevented from being folded.
