Title: Method and coupler for bonding polyolefin pipe
Inventor: TOREBUAA JIYOOJI SUTATSUFUOODO
IPC: F16L13/00
Filed: 1992-04-23
Abstract: PURPOSE: To realize coupling of large-diameter pipes by forming a coupler having an open-end hollow body of a non-conductive crosslinked polyolefin material to allow the couple to have a first minimum inner diameter before heating and a second minimum inner diameter smaller than the first inner minimum diameter after heating. CONSTITUTION: A coupler 10 is made of a polyolefin, for example, polypropylene, polybutylene or the like. The coupler 10 and polyethylene pipes 12, 14 arranged by matching their ends to be bonded integrally with each are assembled, and a heating element 18 is wound in a slot in a saw-tooth outer surface of the coupler 10. A gap 22 exists between an outer surface of the pipe 14 and the minimum inner diameter of the coupler 10 having an inner thread 20. Heating is carried out with the heating element 18, and outer surface temperatures of the coupler 10 and one of the pipes 12, 14 are monitored. The coupler 10 contracts above the pipes 12, 14, and the saw-tooth inner surface of the coupler 10 bites into the outer surfaces of the pipes 12, 14 and mechanically locked with bonding surfaces.

Title: Molded product to which tensile stress is applied and its molding method
Inventor: KATAOKA HIROSHI
IPC: B29C61/06
Filed: 1989-04-25
Abstract: PURPOSE:To make a deformation against bending little, by a method wherein the circumference of a biaxially oriented sheet of thermoplastic resin is fixed with a fixing means and a tensile stress is applied onto a sheet surface extending over the whole directions. CONSTITUTION:The circumference of a biaxially oriented sheet 19 of thermoplastic resin is fixed with a fixing means 20 and tensile stress is applied onto a sheet surface extending over the whole directions. Although synthetic resin forming the oriented sheet can be used widely as the thermoplastic resin, hereupon, ultra-high-molecular-weight body of methacrylate resin can be used most favorably. When an adhesive matter is heated at a temperature of at least the glass transition temperature, the sheet 22 of an outside part of the fixing means 20 becomes a thick part 23 through contraction and the tensile stress is acted upon the sheet 19 of an inside part of the fixing means. With this construction, even though the sheet is thin, a deformation can be made extremely little even if force is applied to the sheet surface.

Title: Driving circuit for step motor
Inventor: KAWAGUCHI NORIO
IPC: H02P8/00
Filed: 1978-08-26
Abstract: PURPOSE:To drive a step motor under an optimal condition, by changing the width of driving pulses depending on the variation in the voltage of power. CONSTITUTION:When a clock signal is applied to an input terminal Vin, a field- effect transistor FET2 is turned on the another field-effect transistor FET3 is turned  off and a capacitor C2 is quickly charged to the voltage VDD of power. When the  potential of the clock signal becomes low the field-effect transistor FET2 is turned  off and the other one FET3 is turned on and the capacitor C2 is discharged through  the latter transistor FET3. When the terminal voltage of the capacitor C2 falls to  a half of the power voltage VDD, the action of an inverter INV is switched over  and an output pulse of width corresponding to the power voltage VDD appears on  an output terminal Vout. The output oulse pulse is applied to the step motor.

Title: Preparation of cyclic organic carbonate
Inventor: MATSUDA HARUKAZU
IPC: C07D317/38
Filed: 1982-06-18
Abstract: PURPOSE:To prepare the titled substance by reacting an organic epoxide with carbon dioxide gas in the presence of a highly active catalyst composed of an organic selenium compound or its mixture with an organic Lewis base. CONSTITUTION:The titled substance is prepared by reacting an organic epoxide with carbon dioxide gas in the presence of an organic selenium compound at 100-150 deg.C under the presence of >=10kg/cm<2>G for 1-5hr. The organic selenium compound is e.g. the compound of formula I , formula II, etc., and its amount is 0.005-0.1mol per 1mol of the epoxide used as the raw material. When the catalyst activity is undesirably low by the single use of the organic selenium, it can be remarkably improved by combining 0.5-5mol of a proper organic Lewis base (e.g. triphenylphosphine, pyridine, etc.) with 1mol of the organic selenium compound.

IPC: G09F3/10
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a linerless label continuous body which prevents a release agent from penetrating a label base material by resolving the problem that the release agent like a silicone penetrates the label base material (slick paper) to bring about a defect that a peelable layer cannot be formed at the time of directly applying the release agent on the surface of the label base material. SOLUTION: The rear face of a label base material (slick paper) 1 is coated with an adhesive layer 2, and the front face of the label base material 1 is coated with a transparent high polymer material 3 (a resin hardened by ultraviolet rays and a hot melt adhesive) to be a reception layer, and the surface of this high polymer material 3 is coated with a release agent 6 like a silicone. Since the transparent high polymer material 3 forms a thin film on the label base material 1, characters, graphics, etc., printed on this surface are not blurred and are made vivid. Further, an effect that the print on the surface of the label base material 1 can be distinctly confirmed is given because the high polymer material 3 made transparent is formed on the surface of the label base material 1.

Title: Automatic playing device
IPC: G10H1/00
Filed: 1992-03-31
Abstract: PURPOSE:To perform tempo control without disorder by inhibiting tempo setting operation by a player from being reported when external tempo control data are made effective. CONSTITUTION:When an internal control mode is set with a mode setting switch 14 provided on an operation panel OP, a tempo can be set with a tempo setting switch 10 and tempo control corresponding to a tap on a tap pad 18 can be performed.

Title: Optical scanner
Inventor: YAMAGATA KIYOHIRO
IPC: B41J2/44
Filed: 1986-05-07
Abstract: PURPOSE:To simplify an optical system, and to make its cost low by forming the surface, opposed to a deflector of a surface inclination correcting cylindrical lens of a rotary polygon mirror, into a plane, and using a plano-convex cylindrical lens. CONSTITUTION:A laser beam emitted from a semiconductor laser 1 is converted to parallel rays by a collimator lens 2, condensed by an image forming lens 3, and brought to a linear image formation onto a deflecting surface of a rotary polygon mirror 5 by a one-direction condensing lens having an image forming capacity in only the direction vertical to the deflecting surface of the rotary polygon mirror 5. The laser beam is reflected and deflected by the deflecting surface of the rotary polygon mirror for rotating at a uniform speed in the direction as indicated with an arrow, made incident on a plano-convex cylindrical lens 6 and reaches on a recording body 7. By the plano-convex cylindrical lens 6, the deflecting surface of the rotary polygon mirror 5 and the recording body 7 being the surface to be scanned are in a conjugate relation, therefore, even if the deflecting surface of the rotary polygon mirror 5 is inclined from 5a to 5b, the laser beam follows an optical path of a broken line and always forms an image at a point (c) on the recording body 7, and a surface inclination of the deflecting surface of the rotary polygon mirror 5 is corrected. In this way, an optical system having a good aberration correcting effect can be simplified.
