Title: B scope recording method of ultrasonic flaw detector
Inventor: OGATA TAKAHARU
IPC: G01N29/44
Filed: 1981-12-25
Abstract: PURPOSE:To record a defect distribution depending on the depth-wise position of work by zigzaging a recording pen of an X-Y recorder at a fixed pitch in linkage with a reciprocal scanning of an ultrasonic probe on the surface of the work in one direction. CONSTITUTION:A probe 2 of an ultrasonic flaw detector 1 scans repeatedly over the desired section of work 3, preferably the section S where a scan C confirms the presence of internal defects P and Q. Corresponding to the repeated scanning of the probe 2 over the section S, an X-Y recorder 5 zigzags a recording pen 6 on an X-Y recording surface 5a along an imagenery line F according to the command from a control circuit 4. A detect gate signal is outputted in a sequential shift corresponding to thickness-wise divisions of the work each time the probe 2 scans and when it coincides with a flaw detection signal of the probe 2, the pen 6 is caused to record flaw marks P' and Q', for example. This enables the recording of even thickness positions of internal defects on the X-Y recording surface to ensure three-dimensional capture of internal defects of the work.

Abstract: PURPOSE:To prevent voids from being generated in an interlayer insulating film formed on a wiring by a method wherein a wiring layer formed on a semiconductor substrate is tapered by etching carried out in n-stages (n>=2) so as to lessen in angle of tapering as etching proceeds to its upper part. CONSTITUTION:An Al film 53 is deposited on an insulating film 52 provided onto a semiconductor substrate 51, and a photoresist 54 is deposited thereon and patterned. Then, the Al film 53 is tapered by etching so as to have a first angle of tapering up to a halfway point. In succession, the Al film 53 is tapered by etching so as to have a second angle of tapering larger than the first. Then, a metal wiring layer of Al film 53 possessed of two angles of tapering can be obtained. By this setup, voids can be prevented from being generated in an interlayer insulating film formed on a wiring layer.

Title: Fuel controller for internal combustion engine
Inventor: IIDA KAZUMASA
IPC: F02D41/06
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To improve the startability of an in-cylinder injection engine at low water temperature as well as shortening starting time. SOLUTION: Cylinder identification is conducted, which discriminates respective cylinders when starting of an in-cylinder injection engine 1 is detected. After the discrimination of the respective cylinders, it is discriminated whether or not water temperature detected by a water temperature sensor 16 is a prescribed one or more.

Abstract: PURPOSE:To prevent an oxide film for isolation from intruding into a silicon oxide film for mask, by forming side walls of silicon nitride film on the side of at least the silicon oxide film between the silicon oxide film and a silicon nitride film which form a mask for selective oxidation. CONSTITUTION:A first silicon oxide film 7 is first formed on a silicon substrate 6, and a first silicon nitride film 8 is then deposited on the first silicon oxide film 7. A second silicon oxide film 9 is next deposited on the first silicon nitride film 8, and a photoresist pattern 10a is thereafter formed. And, using the photoresist pattern 10a as a mask, a second silicon oxide film pattern 9a is formed, and silicon nitride film pattern 8a is then formed. Next, using both the photoresist pattern 10a and the silicon nitride film pattern 8a as a mask, a first silicon oxide film pattern 7a is formed. Subsequently, a second silicon nitride film 11 is deposited over the substrate body in order to form side walls 11a. Moreover, using the second silicon oxide film pattern 9a as a mask, the non-active area of the silicon substrate 6 is etched to form a groove 12. Finally, the entire surface of the silicon substrate 6 is oxidized, which results in a silicon oxide film 13 being selectively formed in the groove 12 of the silicon substrate 6.

Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To reduce engine noise and vibration arising from charging, while preventing the lack of stored electricity in an electricity storage device when a vehicle is in a state of near halt with its speed dropping to a given value or lower in a power generation controlling device for a hybrid vehicle, which drives a generator with an engine for charging the electricity storage device. SOLUTION: If it is discriminated that a speed V of a vehicle is equal to a given value α or lower (SA4) and that state of charge SOC is equal to a given capacity β or lower (SA6), target engine speed is reduced by a given value (SA11) so that the current of a motor generator is controlled, in such a way as to generate regenerative braking torque which matches a target engine speed (SA12) to reduce the charging capacity. On the other hand, if the amount of change of the stored electricity capacity ΔSOC becomes negative, the power consumption of an electrical load is lowered (SA and SA4) in such a way that the charging and discharging of an electricity storage device is almost balanced.

Abstract: PURPOSE: To curve and propel a shield excavator without varying the clearance between an outside plate and an outer peripheral surface by making the center position of first tilting coincide with the center position of second tilting, and placing seals between a rear shell portion and a front shell portion that undergoes the first tilting and between the front shell portion that undergoes the first tilting and a cutter head that undergoes the second tilting. CONSTITUTION: A front-shell curving cylinder 51 expands and contracts as it feeds pressure oil via a switching valve. A front shell portion 20 is tilted about a connecting pin 45 at a predetermined angle to a rear shell portion 10. Similarly, a curving cylinder 55 expands and contracts via a switching valve. A cutter head portion 30 is tilted about the connecting pin 45 at a predetermined angle to the front shell portion 20. Since the connecting pin 45 is located on a center line between center positions 0a and 0b, the cutter head 30 is continuously titled relative to the rear shell portion 10. Therefore, machine length can be reduced and the radius of curvature reduced. Also, seals 41, 42 prevent earth and sand from entering. The manufacturing cost can then be reduced.
