IPC: F03G7/00
Filed: 1987-10-26
Abstract: PURPOSE:To obtain the stable noncontact torque, by setting a part of the superconducting substance of a superconducting substrate in a normal conduction state, with an energy feeder. CONSTITUTION:A power generating set is composed of a superconductor 1, a permanent magnet 2, and a laser generator 3, and laser 4 from the laser generator 3 is irradiated to the superconductor 1, and the irradiated section is phase-transferred in a normal conduction state. As this result, the superconductor 1 is divided into a superconduction state section 1a and a normal conduction state section 1b, and has no Meissner effect in a normal conduction state, and so a part of a magnetic flux line from the permanent magnet 2 passes the section 1b. At this time, the superconducting unit 1 is moved in the direction of an arrow head 5 receiving a force. The force is generated in order according to an area receiving the irradiation of the laser beam 4, and the superconductor 1 can be driven coming in non-contact with the laser generator 3 and the permanent magnet 2.

Title: Thermal transfer recording sheet
Inventor: YAMAGUCHI YOSHITAKA
IPC: B41M5/42
Filed: 1984-12-21
Abstract: PURPOSE:To obtain a thermal transfer recording sheet free of lowering in transfer quantity at the time of overlap transfer, by providing adhesive layers respectively between an ink layer and a base and on the upper surface of the ink layer. CONSTITUTION:The thermal transfer recording sheet comprises an undercoat layer 3, an ink layer 4 and a topcoat layer 5 in a three-layer construction on the base 2. When thermal transfer in the second color is performed, a transfer recording paper 7 carried thereon the topcoat layer 5, the ink layer 4 and the undercoat layer 3 for the first color which has been transferred onto the paper 7, a portion of the topcoat layer and the ink layer being absorbed into the paper 7. Heat generated by a thermal head 7 is transmitted to the base 2, thereby softening or melting a thermal recording layer 6 and thermally transferring it onto the paper 7. In this case, the undercoat layer 9 for the first color (the undercoat layer 3 is transferred to the paper to become the layer 9) and the topcoat layer 5 for the second color are mixed with each other, and are adhered, thereby overlapping the color. Releasing takes place between the base 2 and the undercoatd layer 3. Accordingly, even at the time of overlap transfer, the transfer quantity is prevented from being reduced, and high-quality images can be formed.

Title: Control circuit of motor
Inventor: TADA TAKATOMO
IPC: H02P29/00
Filed: 1984-12-21
Abstract: PURPOSE:To detect the presence of the rotation of a motor and to control the speed of the motor with a simple construction by detecting a motor noise. CONSTITUTION:When a signal shown in a waveform A from the collector of a transistor Q6 is applied as a motor noise through an inverter 1NV, a transistor Q7, an operational amplifier Q8 to a low pass filter made of a resistor R9 and a capacitor C3, a smoothed signal shown in the waveform E is obtained. When the rotating speed of a reel motor RM is accelerated, the motor noise generated at the collector of a transistor Q1 is increased proportionally to it, resulting in an increase in the voltage level of the signal E. Thus, the base voltage of a transistor Q3 is increased to reduce the ON resistance between the collector and the emitter. Thus, the emitter voltage of the transistor Q1 is dropped to decelerate the speed of the motor RM.

Title: Treatment of sponge titanium powder
Inventor: ARAKAWA KAZUAKI
IPC: B22F9/04
Filed: 1994-10-07
Abstract: PURPOSE: To produce intermediate titanium powder adequate for moldings of titanium and titanium alloy by a powder metallurgical method. CONSTITUTION: Sponge titanium obtd. from sponge titanium is charged pat together with media into a mill pot of a planetary ball mill and is crushed and compacted to a flaky form by maintaining an inert atmosphere in the pot. Further, the sponge titanium powder is finely segmented and sized in a medium agitating mill, by which the grain size and the grain shape are adjusted. The sponge titanium powder is thereby reformed to the intermediate titanium powder having the excellent flow property adequate as a starting raw material of the titanium moldings and a large bulk sp. gr.  As a result, the moldings having the characteristics, such as high sp. strength and high fatigue resistance, intrinsic to the titanium, are produced by using the inexpensive low-purity powder and subjecting the powder to powder molding and sintering alone without subjecting the powder to other stages, i.e., hydrogenation dehydration treatment, HIP treatment, heat treatment, surface treatment, etc., at all.

Title: Discharge-type light emission device
Inventor: KAN FUMITAKA
IPC: H01J11/42
Filed: 1985-12-03
Abstract: PURPOSE:To reduce a cross talk and heighten the luminance of light emission even for a large surface area, by placing an electrode on the side of a base plate whose other side is in contact with a dielectric layer to lower the electrostatic capacity between the upper and lower electrodes. CONSTITUTION:A base plate 2 has a large number of holes 5 in positions corresponding to those of electrodes 11. The inside surfaces of the holes 5 are coated with side conductors 6. An electrode 12 is electrically coupled to the side conductor 6 for the hole 5 and disposed on the side of the base plate 2 whose other side is in contact with a dielectric layer so that the electrode 12 extends nearly perpendicularly to the electrodes 11. As a result, a needless electrical current caused by electrostatic capacity is much decreased. Since discharge is independently caused in each hole 5, a cross talk is prevented. Since a large surface area of enough light emission can be provided, a high luminance of light emission can be attained even for a large surface area.

Abstract: PURPOSE:To minimize the loss of valuable prints due to troubles in paper feeding, by providing a printed mark-detecting means which detects detection marks printed outside a designated printing character area on the printing paper at regular intervals corresponding to a fixed line spacing quantity and judges the propriety of paper feeding on the basis of a feed quantity of a paper-feeding means and a detected interval of the detection marks. CONSTITUTION:At the time of printing on a printing paper 1 fed in the direction of an arrow B by driving a tractor 2, for example, solid-printed detection marks 6a, 6b, 6c are provided in an area in the exterior of a printing area C at regular intervals corresponding to a fixed line spacing. A printed mark-detecting means 5 is located on the upper side of the detection marks 6a-6c, and sequentially detects the detection marks in the order of 6a 6b 6c as the paper 1 is fed. In the case of normal paper feeding, the detection marks 6a-6c are detected one for each fixed-line-spacing amount of feed by the tractor 2. When the interval at which the detection marks 6a-6c are detected does not agree with the fixed line spacing, it is judged that a trouble (skewing, jamming, breakage or the like) in paper feeding is generated, and a printer is instantly stopped.
