Title: Liquid crystal display device and defect correcting method for the same
Inventor: MAEDA TOSHIO
IPC: G02F1/1343
Filed: 1991-03-29
Abstract: PURPOSE:To realize the liquid crystal display device which is applicable to both a projection device and a direct view type. CONSTITUTION:Once a bright point picture element 5 is detected, an excimer laser oscillator 11 irradiates the surface of a glass substrate 2, on the incidence side of a liquid crystal panel 1, on the same irradiation path with the bright point picture element 5 with a laser beam 12 to perform excimer laser etching, thereby forming a recessed part 18, which is so deep that the bottom surface is close to the bright point picture element 5, in the irradiated part of the glass substrate 2. At the same time, a rough surface 17 is formed as the bottom surface. Consequently, the light passing through the bright point picture element 5 is reduced to correct the bright point picture element so that the picture element is inconspicuous as compared normal peripheral picture elements 50. Further, the rough surface 17 is put close to the bright point picture element 5, and then the bright point picture element 5 is viewed in the corrected state at any view angle on the surface side of a projection-side glass substrate 3.

IPC: H04N5/232
Filed: 1987-03-20
Abstract: PURPOSE:To perform a level control without slowing the change of a focus voltage by performing the level control by subtracting a prescribed level from the focus voltage, when the focus voltage comes higher than the prescribed reference level, accompanying focusing. CONSTITUTION:A video signal S1, outputted through an amplifier 13, is supplied to a BFP 15 and a detector 16, and the focus voltage E is detected. Respective subtracters, connected in series, subtract the prescribed level h1 apiece from the input focus voltage E1, and a signal switcher 18 switches a signal line in a direction from E1 to E4 successively, at every time when the focus voltage E1 of the detector 16 or the voltages E2-E4, after the subtraction by the respective subtracters 19, reach the prescribed Emax. As the result, the focus voltage outputted from the signal switcher 18, is suppressed always between the reference level Emax and the level K1Emax which is the prescribed number times of the Emax. The output voltage of the signal switcher 18 is inputted to a focusing control circuit 17 as the focus voltage, after it is subtracted by a prescribed value by the subtracter 20, amplified by the amplifier 21, and digitized by an A/D converter 22.

Abstract: A novel prosthesis for use in repairing or replacing soft tissue is disclosed, which comprises a triaxially-braided fabric element having interwoven first, second and third sets of fibers, with the fibers of the second and third sets being oriented at substantially the same acute braiding angle with respect to the fibers of the first set. An elongated ligament prosthesis exhibiting the desired properties of high strength and high elasticity may be prepared by selecting high elasticity fibers for the first set, orienting said first set of fibers in the longitudinal direction of the prosthesis and selecting fibers having high yield strength and high Young's modulus for the second and third sets. A tubular prosthesis in which high elasticity fibers are oriented in the longitudinal direction is highly suitable for use as a vascular prosthesis. A prosthesis of the invention may also be manufactured in the form of a prosthetic heart valve leaflet.

Title: Trouble detecting circuit of current-type inverter
Inventor: OOSAWA YOSHINOBU
IPC: H02M7/515
Filed: 1978-06-02
Abstract: PURPOSE: To detect trouble and ensure safety by giving consideration to the fact that both terminal voltages of a pair of arms having the identical waveforms when an inverter circuit is in normal operation assume extremely different waveforms when any trouble occurs in the thrristor of the inverter circuit.  
     CONSTITUTION: When a thyristor element of inverter circuit 3 is broken down, or when commutation fails, as is clear by comparison of C 1  and C 2  in the drawing, each thyristor voltage (VT 2  and VT 3 ) of a pair of arms of inverter circuit 3 does not assume an identical waveform. Consequently, different voltages appear, and until detecting transformers 61 and 62 are saturated, an output appears on the outut winding of transformers 61 and 62. For this reason, it is possible to detect a breakdown in inverter circuit 3 or a commutation failure by operating voltage relays 71 and 72 by this output.

Title: Soldering terminal
Inventor: ISHIKAWA TETSUYA
IPC: H05K3/34
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent fused solder from creeping on the side surface of a flat part, by forming a penetrating hole linking with a gap part, in the flat part. SOLUTION: On the plate surface facing the stretching part 44b of a flat part 43, a penetrating hole 43a is formed, and a gap 45 is linked with the solder surface of the flat part 43 by the penetrating hole 43a. Fused solder permeates into the gap between the flat part 43 and a pad 2a and the gap 47 between a bent part 44a and the pad 2a. At the same time, the fused solder flows into a gap part 45 through the penetrating hole 43a of the flat part 43, by the effect of surface tension of the fused solder. When the solder is cooled and hardened, solder fillets 5a, 5b in gap parts 46, 47 form a solder layer 5c in the gap part 45 and the penetrating hole 43a. Fused solder interposing between the flat part 43 and the pad 2a is sucked into the gap part 45 through the penetrating hole 43a formed in the flat part 43.  By this sucked solder amount, the solder is made hard to creep on the side surface of the flat part 43. Hence the solder fillet does not become large on the side surface of the flat part 43, so that it can be prevented that a solder bridge due to solder fillets is generated between adjacent terminals.

Title: Rotor for turbo particle pump
Inventor: NARITA KIYOSHI
IPC: F04D19/04
Filed: 1985-03-30
Abstract: PURPOSE:To securely prevent a resonant phenomenon which has existed in a rotor by providing plural projected or recessed parts on the inner periphery of a bell-shaped rotor and greatly varying the natural frequency of said rotor by means of the partial slight change in the wall thickness. CONSTITUTION:Five recessed parts 4, 4... which is formed by notching the thick wall of a large-diameter cylindrical part 1B into a shallow arc form, is provided on the inner periphery 1b of the large-diameter cylindrical part 1B of the bell-shaped rotor 1 at an equal angle and interval with respect to the center O. Thereby, the natural frequency of the bell-shaped rotor 1 can be greatly varied from one on which the recessed parts are not yet provided, removing at all or remarkably reducing an uncomfortable resonant sound. Since these recessed parts 4, 4... are provided at an equal interval, the dynamic balance of the rotor 1 is not lost. Also, the recessed part which is effective merely with a very small depth, will not have an adverse effect on the strength of the rotor 1 which is subjected to a strong centrifugal force under an ultra-high speed rotation, securely preventing a troublesome driving sound.
