Title: Production of circumferential barrel ring for construction of cylindrical storage tank
Inventor: UENO YASUSHI
IPC: B21D51/18
Filed: 1979-12-25
Abstract: PURPOSE: To obtain a ring which is of uniform curvature over the entire circumference, has high roundness and has no rubbing flaws by forming a guide member which winds the steel strip formed to required curvature into a freely rotatable ring of which the center is determined by 3 or more vertical rolls.  
     CONSTITUTION: A dummy sheet steel 21 is inserted into a bending machine 3, and the trailing end thereof and the leading end of a steel strip coil 1 are joined. Next, the bending machine 3 is driven to unroll and form the coil 1 and advance the curved steel strip 4. The part of unstable curvature near the leading end thereof is cut off. Thence, the machine 3 is operated continuously and while the coil 1 is formed to the curved steel strip 4 of predetermined curvature, it is wound on the outside circumference of a guide ring 10. The ring 10 has a radius of curvature approximately equal to the radius of the forming curvature of the steel strip 4. The center of its rotation is determined by three vertical rolls 11 on the circumference, and the ring is supported by horizontal rollers 12. Where the steel strip 4 of a predetermined ring circumferential length is obtained, the winding is stopped and  the steel strip 4 is cut, after which it is removed from the bending device by a hoisting device and the cut ends are butt-welded.

Title: Optical information recording apparatus
Inventor: KUROODO PIYUUSHIYU
IPC: G11B7/24
Filed: 1991-06-12
Abstract: PURPOSE: To provide an optical data storage device whose information storage capacity is larger than that of a conventional data storage device. CONSTITUTION: Information elements are stored in the volume of a transmission layer instead of being stored on the surface of the layer. Different plural information strings are respectively stored in the different plural hierarcies of the transmission layer. Write/read means are designed so that a light beam is converged in the plane of a prescribed hierarchy without being converged in other hierarchies. Variations of light beams respectively generated in individual hierarchies are selectively detected by photodetectors. The layer of the optical transmission material is desirable to be a material inducing the changing of a refractive index by light.

Abstract: PURPOSE:To enlarge single-crystal islands in thickness by a method wherein a laminate substrate is formed of two substrates sandwiching an element isolating insulating film and another insulating film of a different material and one of the substrates constituting the laminate is divided into a plurality of insular semiconductor layers. CONSTITUTION:A surface is mirror-polished of a silicon substrate 10 and of a silicon substrate 12 and, thereon, a thermal oxide film 11 and a silicon nitride film 13 are formed, respectively. The polished surfaces are then bonded for the formation of a laminate substrate. The surface of the silicon substrate 10 now in the laminate is polished and then subjected to etching for division into single-crystal islands 10-1 and 10-2 and a region free of a single crystal. Next, the thermal oxide film 11 is locally removed for the exposure of the silicon nitride film 13. A thermal oxide film 14 is formed in the vicinity of the single crystals. A process follows wherein only the nitride film 13 is removed for the exposure of the surface of the silicon substrate 12, which is followed by the depositing of an epitaxial layer 16 on the silicon substrate 12. During this process, on the other parts of the thermal oxide film 11, a polycrystalline silicon layer 17 is deposited. Abrasion is performed from the surface for the exposure of the single-crystal islands 10-1 and 10-2 and the thermal oxide film 14, thickening the islands.

Title: Method for applying mold coating material on expendable pattern for casting
Inventor: IMAI MINORU
IPC: B22C9/04
Filed: 1989-06-29
Abstract: PURPOSE:To prevent the collapse of a casting mold and to prevent the generation of casting defects by applying an ag. soln. essentially consisting of a binder set in viscosity at a specific value on the surface of expendable patterns to form a binder layer and sticking the deposits, such as particles of refractories, to the surface of the binder layer. CONSTITUTION:The expendable pattern bodies 1, 2 are immersed into the aq. soln. essentially consisting of the binder set in viscosity at 1 to 2000cp to form the binder layer 9. The aq. soln. essentially consisting of the binder infiltrates the inside of the imperfectly joined surfaces D, flaw parts E, recesses C of bead patterns, etc., of the respective constituting parts 1a, etc., on the surface of the expendable pattern bodies 1, 2. The filling up of the surface is thus executed. The deposits, such as particles or powder and flakes, of the refractories 10 are stuck onto the entire surface in succession to this treatment. Silica and zirconia are used as the refractories and mica, etc., are used in the case of the flakes. The generation of the casting defects is prevented in this way and the fine particles of the refractories are uniformly stuck to the surface. The good casting surfaces are thereby formed on cast products.

Abstract: PURPOSE:To keep operation of an internal-combustion engine stable even when power supply from an operating power source is inerrupted temporarily, by providing a judging means for judging whether the engine is under starting operation or under ordinary operation and a control means for executing starting control or ordinary control. CONSTITUTION:A turning-angle sensor 100 produces a signal representing the turning-angle position each time an internal-combustion engine is turned a predetermined angle, and a detecting means 101 detects the engine speed from the signal representing the turning-angle position.

Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of operation noise and the occurrence of slide resistance, to simplify constitution and reduce size, and to provide a damper function in a stable state. SOLUTION: Damper pistons 91 and 96 are axially slidably supported by a shaft guide 80 and make contact with the protrusion part 24 of an armature body 21 and the protrusion part 43 of an upper retainer 42 in a given position. In a valve drive device 100, a shaft guide 80 and a damper means 90 are integrally formed.

Further, since oil is fed through a groove part 23 to a damper means 90, a damping force to provide a damper function is stabilized and unevenness of damper operation is decreased.

IPC: H02M7/5387
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent ripples from being generated at output, even in the case of a waveform where the absolute value of a power supply voltage fluctuates within a single period by extending a period for supplying energy from a smoothing capacitor to a load for mainly adjusting output and suppressing output decrease. SOLUTION: In a control circuit 1, a signal for correcting an output ripple is obtained with a correction signal formation circuit 7, by detecting the power supply voltage of an input AC power supply Vs. A correction signal from the correction signal formation circuit 7 is inputted to a PWM signal generation part 4a for adjusting output along with an output reference signal 2a, thus adjusting a switching period for transmitting load power. A full-wave rectification waveform is obtained from a power supply voltage waveform as an example of the correction signal formation circuit 7 and the difference signal between the peak value of the pulsation signal. The original pulsation signal is generated as a correction signal, thus obtaining a correction signal for increasing the output at the bottom part of the power supply and inputting it to a PWM signal generation part 4a for adjusting the output and suppressing output ripples.
