Title: Ignition timing control device in internal-combustion engine
Inventor: KOMURASAKI SATORU
IPC: G01M15/00
Filed: 1982-09-01
Abstract: PURPOSE:To carry out the control of spark retardation upon accelerating, etc. with no influence to the degree of control accuracy for enhancing the reliability, by providing a failure detecting part for detecting abnormality in a knocking detecting system so that the control of spark retardation is carried out in accordance with the output of the detecting part. CONSTITUTION:A failure detecting part 22 is provided in an ignition timing control device in which a knocking detection part 7 receiving the detection output of a knocking sensor 10, selectively detects a knocking signal and generates the control voltage of spark retardation in accordance with the strength of knocking so that the control of psark retardation is carried out by applying the control voltage of spark retardation to a phase-shifting part 3. This failure detecting part 22 is actuated, when a predetermined acceleration is established, by closing a switch part 23 by an acceleration detecting part 8. Meanwhile, the failure detecting part 22 issues a failure detection signal when a failure such as, for example, the breaking of a harness between the knocking sensor 10 and the afore-mentioned control device, is occurred, and therefore, the control of spark retardation is carried out by means of the knocking detecting part 7.

Title: Probe card, probe used for it, and manufacturing method for probe
Inventor: OKUBO MASAO
IPC: H01L21/66
Filed: 1995-04-24
Abstract: PURPOSE: To prevent uneven abrasion and adhesion of foreign matter by using a very minute ball-like probe for a contact part in contact with an electrode pad of a probe. CONSTITUTION: Relating to a probe 100 used for a probe card, a contact part 110 at the tip for contact with an electrode pad of an LSI chip, or measurement object, is very minute ball-shaped.

So no such problem as is caused by uneven abrasion of the probe 100, adhesion of foreign matter or oxidation, etc., of the foreign matter stuck is caused. Therefore, usage extending long period is allowed without needing for regular maintenance and interrupting probe work.

Title: Reducing method for gas discharged from vacuum material
Inventor: YOSHIMURA TOSHIHIKO
IPC: H01L21/203
Filed: 1985-07-15
Abstract: PURPOSE:To decrease pressure reached in a vacuum apparatus by a process in a short time at a low temperature futhermore, by aligning the crystal orientation on the surface of a vacuum material, exposing the crystal surface, from which gas is discharged less, and suppressing the gas adsorbed when the vacuum apparatus is opened to an astmosphere. CONSTITUTION:Air is exhausted through a port 2 of a vacuum container 1. The inside of the container 1 is kept at a high degree of vacuum. Molybdenum 5 is a crucible 3 is heated and fused with an electron gun 4. The fused Mo is cast in a mold 6 for an Mo susceptor. With the inside of a mold heating furnace 7 being cooled with a mold cooling plate 9, the Mo is slowly lowered by using a mold lifting shaft 10. Thus the growing of a crystal is enhanced. For the inner wall of the mold heating furnace 7, a graphite susceptor 8 is used. Of the surfaces of the Mo susceptor for attaching a substrate to be made, the surface, to which the substrate is attached and which has the broad area, is aligned in the direction of [110], to which gas is hard to be adsorbed. Thus, the MO susceptor, whose amount of gas discharge is less, can be manufactured.

Title: X-ray tube
Inventor: KOYANAGI KEIJI
IPC: H01J35/10
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray tube wherein X-ray intensity distribution pattern of a focus on its positive electrode target is improved and bimodal property thereof is reduced. SOLUTION: A filament attached to a focusing groove 14 of a focusing electrode 3 of a negative electrode consists of a main filament 11 having a larger outer diameter and an auxiliary filament 12 having a smaller outer diameter, both of these being coil-shaped, the auxiliary filament being arranged inside the main filament, these have the same coil pitch and are arranged in half a pitch shifted manner from each other. Coil apices 12A of the auxiliary filament 12 are each situated in the middle of adjacent coil apices 11A. When an X-ray tube voltage is applied, an accelerating electric field is generated in a peripheral part of the coil apices 12A of the auxiliary filament 12, and electron beams from the apices also contribute to focus formation.  Since the beams have small single modal intensity distribution, when electron beams of the two filaments 11, 12 are composited, bimodal intensity distribution by electron beams of the main filament 11 comes to have a shallow trough in its center part and approximates to the single modal intensity distribution.

Title: Control device for mixing hot and cold water
Inventor: UEKI KOICHI
IPC: F16K31/64
Filed: 1984-07-25
Abstract: PURPOSE:To quickly stabilize temperature of flowing hot water for a preset temperature by continuously controlling driving means for urging a mixing valve corresponding to a detected temperature deviation in such a manner that the driving means is driven by the first urging amount, and when a temperature deviation is below a deviation preset value, the driving means is driven with a gain of the urging amount changed. CONSTITUTION:When a temperature deviation detected by deviation detection means 17 is larger than a preset value Em of the first deviation setting means 18, urging amount setting means 22 outputs the first urging amount F0 to driving means 13. When the temperature deviation comes to the preset value of the first deviation setting means 18, the driving means 13 is driven by the second urging amount F1 smaller than the first urging amount F0. The driving means 13 is continuously controlled until the temperature deviation reaches a preset value Em of the second deviation setting means 19. Thus, the urging amount is continuously changed, so that a mixing valve is prevented from going beyond and returning from the optimum position, that is, hunting.

Abstract: PURPOSE: To produce a seamless steel tube with a fine-grained structure. CONSTITUTION: A hollow tube stock of steel composed essentially of Fe is heated to 1000-1150 deg.C and continuously hot-rolled at a finishing temp. between 1150 deg.C and the Ar3 point. The resulting finished steel tube, whose temp. is lowered to a value between 1150 deg.C and the Ar1 point, is heated to a temp. between the Ac3 point and 1000 deg.C and higher than the above temp. After hot finish rolling at >=(Ar3 point +50) deg.C finishing temp., the steel tube is cooled rapidly from a temp. not lower than the Ar3 point to undergo hardening treatment and then subjected to tempering treatment consisting of heating up to a temp. not higher than the Ac1 point and cooling.  The resulting steel tube has excellent toughness at low temp. and SSC resistance because of its refined grains and produces superior effects particularly in the northernmost cold district and under the sulfide stress corrosion environment.
