Abstract: PURPOSE: To apply a seamlessly printed pattern onto the peripheral surface of a cylinder, by printing the pattern onto the peripheral surface of the cylinder with a squeezee which is in contact with and synchronized with the cylinder to be printed.  
     CONSTITUTION: After a cylinder 1 to be printed is attached to a rotator 9, a screen 4 is lowered to come in contact with the cylinder 1 to be printed, and carried synchronizedly with the peripheral speed of the rotation of the cylinder 1, so that the peripheral surface of the cylinder 1 is printed with a squeezee 10. A part of the peripheral surface opposite to a part 8 in contact with the screen 4 is exposed to the radiation of ultraviolet rays a discharged through the radiation opening 7 of a shade cover 5 from an ultraviolet lamp 6 arranged in the shade cover 5. The arrival of the ultraviolet rays (a) at the screen 4 is intercepted by the rotator 9 and the cylinder 1 to be printed, so that an ultraviolet-curing resin ink 3 on the screen 4 is not cured. After the printing operation is finished, the screen 4 is lifted, and the cylinder 1 to be printed is rotated by a half rotation or more, so as to cure the printed ultraviolet-curing resin 3.

Title: Engine driven alternating current generator
Inventor: ISHIHARA TAKETOSHI
IPC: H02P9/04
Filed: 1980-04-14
Abstract: PURPOSE:To decrease fuel consumption and noise in case of nonload by adjusting the speed of revolution of an engine for driving an AC generator in response to the load currents of the AC generator. CONSTITUTION:When load currents do not flow through a generator 5, a governor lever 1 of an engine 4 is located at the low speed side because a relay 20 is under an OFF condition and an electromagnetic solenoid 3 is excited. When a starting push-button switch 10 is temporarily pushed, the relay 20 is at ON and the governor lever 1 is changed over to the high speed side by the OFF of the electromagnetic solenoid 3 because an electromagnetic switch 11 is conducted temporarily and load currents flow by the conduction. When the starting push-button switch 10 is pushed again at the point of time, the electromagnetic switch 11 self-holds and functions. When a stopping push-button switch 12 is pushed, the relay 20 is at OFF and the governor lever 1 is changed over to the low speed side because the electromagnetic switch 11 is at OFF.

Title: Stroboscopic circuit
Inventor: YONETANI TAKAYUKI
IPC: H05B41/32
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To enable a stroboscope to be charged even during the time when the other actions of a camera are being executed, and to quickly charge it, by providing plural modes that the charge currents of a capacitor are mutually different. SOLUTION: When a harmonic signal (voltage signal) VB is given, a stroboscope charge circuit 2 is actuated and the capacitor for a flash C1 is charged. Since a transistor Q2 is turned on when a control signal CTL is H, a transistor Q1 is also turned on. Then, the capacitor C1 is charged by the normal charge current through the transistor Q1. Besides, since the transistor Q2 is turned off and the transistor Q1 is also turned off when the control signal CTL is L, the charge current becomes low because it is passed through a resistance R1. Then, the capacitor C1 is charged by the low current. In the normal charge mode, the capacitor C1 is charged by the high current of several-ampere. In the low current mode, it is charged by the current of several tens (mA) which does not exert an effect on the action of the camera, for example.

Abstract: PURPOSE:To easily find the symmetric surface of a three-dimensional body by rotating a linear model, obtained from the three-dimensional body, on a proper axis as the center of rotation and finding the extent of asymmetry of the three-dimensional body regarding a reference surface. CONSTITUTION:A three-dimensional measuring instrument 2 measures the three- dimensional body 1 whose symmetric surfaces are to be extracted and obtains three- dimensional coordinate values on the object surface of the three-dimensional body 1.

Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To execute effective pickling treatment and to control the absorption of hydrogen by adding at least one kind of nickel ions and cobalt ions to a mixed aq. soln. of hydrofluoric acid and sulfuric acid to form into a pickling soln. for titanium (alloy). SOLUTION: The mixed aq. soln. of hydrofluoric acid and sulfuric acid contg. no nitric acid is mixed with nickel ions and cobalt ions by 0.1 to 5wt.%. to form into a pickling soln. When the concn. of the ions to be added is less than 0.1wt.%, the effect of controlling the amt. of hydrogen to be absorbed does not shown. When the concn. of the ions to be added exceeds 5wt.%, the loss in corrosion increases and the effect of controlling the amt. of hydrogen to be absorbed is saturated, therefore it is uneconomical. At the time of subjecting the titanium (alloy) to hot working and heat treatment, oxidized scales are generated on the surface. When this pickling soln. is used in the case the scales are removed by a pickling soln., nitrogen oxide having a problem from the viewpoint of environment and whose treatment is difficult is not generated.

Title: Rope weight compensator in linear motor driven elevator
Inventor: NAKAI KEIICHIRO
IPC: B66B9/02
Filed: 1989-02-28
Abstract: PURPOSE: To smoothly correct the weight of ropes by correcting the weight of the ropes, using the weight of cables for supplying driving power to an armature allowed to function as the primary side of a linear motor. CONSTITUTION: Elevating the armature 9 of a linear motor by means of electromagnet force generated between the armature 9 and a fixed column 10 elevates an entire counter weight 4 to elevate an elevator car 3 through ropes 2. Then, the counter weight 4 is equal to the entire elevator car 3 in weight. Assuming that the counter weight 4 is located at the lowermost position; the elevator car 3 is located at the uppermost position, the weight of the ropes equivalent to the difference in weight between the counter weight 4 and the elevator car 3 (L1 -L2 ) is offset by the weight of cables 18 corresponding to the difference (L1 -L2 ). The result lowly sets the required output of the linear motor.
