Patent JP-H04277928-A (JP)
Title: Analog-to-digital converter provided with drift compensation and measuring system including it
Inventor: DONARUDO AREN
IPC: G06F3/038
Filed: 1991-10-07
Abstract: PURPOSE: To simultaneously compensate input drifts when analog signals are digitized by compensating the drifts of DC signal levels through two kinds of correlated digital processing. CONSTITUTION: Since a digital offset tracks the drift of a signal level and is subtracted from the drift when the drift lies between the upper and lower limits, the drift does not appear in the digitized output of an A/D converter 20. When the drift exceeds the upper or lower limit, however, the bias level in the input of the converter 20 is adjusted. Consequently, a step input is generated and compensated in the digitized output of the converter 20 by forcibly changing the digital offset independently from a tracking means 130. Therefore, the digitized output can be corrected without interrupting the continuous digitization of the analog input signals.

Title: Flat crt
Inventor: SAWARA HIROSHI
IPC: H04N3/22
Filed: 1992-09-29
Abstract: PURPOSE:To prevent a zooming phenomenon without using a high voltage regulator and to reduce the over scanning amount of a beam by varying a horizontal deflection voltage level in accordance with the increase/decrease of anode voltage. CONSTITUTION:A high voltage generation circuit 1 supplying anode voltage HV to the anode of CRT and a horizontal deflection circuit 7 supplying horizontal deflection voltage to a horizontal deflection coil 12 are separated, and a correction power source part 16 obtaining low voltage DELTAHV proportional to the increase/decrease of anode voltage HV is provided. The correction power source part 16 has a capacitor 17 and one end is connected to a flyback transformer 2 through a diode 18 and it is charged by pulse voltage. Thus, low voltage DELTAHV proportional to anode voltage HV is charged. One end of the capacitor 17 is connected to a transistor 9 through a resistor RL and voltage to which only low voltage DELTAHV is added is impressed on a transistor 10. Thus, the picture size of the beam becomes constant since horizontal deflection voltage varies in proportional to the increase/decrease of anode voltage HV.

Title: Method for preventing generation of interference pattern generated on roll to be engraved
Inventor: TAKAKURA KOICHI
IPC: B41C1/05
Filed: 1991-09-11
Abstract: PURPOSE:To allow the execution of high-quality engraving without generating interference patterns and to prevent the generation of the interference patterns to be generated on a roll to be engraved in the method for engraving the roll to be engraved by a laser exposing method. CONSTITUTION:An aq. soln. consisting of polyvinyl alcohol(PVA) as a required high- ratio component and silicon dioxide as a required slight-ratio component is applied by overlap coating on a photosensitive film as a protective film for preventing the oxidation at the time of reaction of the photosensitive film with a laser beam. This aq. soln. turns into a colloidal soln. in which the PVA is completely dissolved and the microparticles of the silicon dioxide are uniformly dispersed in the lump state aggregated several pieces to several tens pieces thereof. Then, the lumped particles aggregated with several pieces to several tens pieces of the microparticles of the silicon dioxide are eventually dispersed uniformly into the protective film for preventing oxidation applied by overlap coating on the photosensitive film. Adequate irregular reflections can be applied to the incident light and reflected light of the laser beam within the protective film, by which the generation of the interference pattern to be generated on the roll to be engraved is prevented and the engraving without generating the interference patterns is executed.

IPC: B24B13/02
Filed: 1986-10-31
Abstract: PURPOSE:To always supply satisfactory polishing liquid to aim at efficiently polishing a workpiece with a high degree of accuracy, by providing such an arrangement that a pot-like cavity for reserving polishing liquid, formed in the direction of the rotary axis of a polishing tool, has a diameter on the side where a member to be polished is mounted, which is made to be smaller than that of others. CONSTITUTION:When a polishing tool 1 is rotated at a high speed, polishing liquid 3 flows into the outer peripheral section of an outer peripheral liquid tank 5 under centrifugal force so that the quantity of polishing liquid in a cavity 2 becomes less, but the level of the liquid in the cavity 2 is maintained to be constant by regulating the opening degree of a pipe restricter. Further, a pump 6 lifts up the polishing liquid from the outer peripheral section of the liquid tank 5 and allows the same to flow into a liquid tank 8 so that the liquid is fed in circulation from a supply pipe 9 to the cavity 2. In this arrangement, the opening of the supply pipe 9 is positioned in the vicinity of the bottom surface of the cavity 2 so that the polishing liquid fed into the cavity 2 comes upward while rotating in association with the rotation of the polishing tool 1. Further, large size abrasive particles, foreign matter having large specific weights and the like are aggregated in the outer peripheral section 2a under centrifugal force while small size abrasive particles alone are allowed to flow out from a small diameter part 2b and then onto the upper surface 1a of the polishing tool, thereby the abrasive particles polish a surface 4a to be polished while passing thereon.

Title: Ti-al powder metallurgical alloy
Inventor: KUSAKA KATSUJI
IPC: C22C14/00
Filed: 1986-10-31
Abstract: PURPOSE:To improve the toughness, ductility, strength, and oxidation resistance at high temp. of a sintered alloy, by adding specific amounts of Si and B to a Ti-Al alloy. CONSTITUTION:The alloy has a composition consisting of 30-45% Al, 0.2-5.0% Si and/or 0.02-0.3% B, and the balance Ti and containing, if necessary, 0.2-3% REM. This alloy is formed into a powder by the ordinary melt spraying process, which is formed into a sintered compact. In the alloy of the above composition, when proper amounts of Si and B are added, the surfaces of TiAl grains are cleaned and, as a result of increase in sintering reaction due to reduction in covalent bonding property, strength of the sintered compact is increased and toughness and ductility are improved. When Si content exceeds 5.0%, strength characteristics inherent in Ti-Al alloys are lost and, moreover, when B content exceeds 0.3%, strength is deteriorated and embrittlement is brought about. Further, REM has a function of increasing oxidation resistance at high temp.

Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a chain expanding degree diagnosing device which can prevent a damage of a chain expansion detector, as well as can diagnose the expanding degree of a driving chain easily and accurately. SOLUTION: While a driving chain 11 is held by chain guide bodies 14 and 15 from both sides, a chain expansion detector 13 is buried to one side chain guide body 14. As a result, even though the driving chain 11 is vibrated up and down during the driving, the vibration of the driving chain 11 can be suppressed by engaging the chain guide bodies 14 and 15 in the holding condition from both sides. And at the same time, since the chain expansion detector 13 is buried to one side chain guide body 14, the distance between the driving chain 11 and the chain expansion detector 13 can be maintained constant.
