Title: Device for detecting suction negative pressure of internal combustion engine
Inventor: YUZURIHA YOSHIKI
IPC: G01L23/24
Filed: 1990-02-08
Abstract: PURPOSE:To enhance a degree of freedom of a position for arranging an intake air pressure sensor by providing it in a capacity chamber, which communicates with the downstream side from an intake throttle valve, and providing a fine air amount introducing pipe line through which the capacity chamber communicates with the upstream side of the intake throttle valve when it has a small opening. CONSTITUTION:A fine amount of air, guided from a flow position just below an air cleaner 8 on the upstream side of an intake throttle valve 9 in an intake passage 12, is allowed to always flow in a small chamber 14 as a capacity chamber through a pipe line 16. Here the air flows through the pipe line 16 by a differential pressure between a pipe line 13 and the pipe line 16, except at the time of fully opening the intake throttle valve 9, and similarly to a flow of air in the intake passage 12 at the time of fully opening the valve. Thus by an inflow of fine amount of air in the small chamber 14 always through the pipe line 16, water, oil, gasoline, etc. are not infiltrated in the small chamber 14, while the infiltrated water, oil, gasoline, etc. are discharged to the intake passage 12 side through the pipe line 13, and these water, oil, gasoline, etc. are prevented from infiltrating in an intake air pressure sensor 15.

Title: Method and equipment for analyzing failure of semiconductor device
Inventor: SAKATA MASAO
IPC: H01J37/256
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To enable correspondence of inspection coordinates to observation coordinates, by forming a sign coordinate mark on a wafer in every photo process of a forming process of a semiconductor wafer, specifying coordinates on a chip from the mark, and observing them. SOLUTION: Sign coordinates are formed in the photo process of a manufacturing process. The sign coordinates are formed on a scribe line between chips by using a sign pattern 502 of a reticle pattern. Reticle is repeated about 10-50 times in the manufacturing process of semiconductor. The position of the sign pattern is changed in every photo process, and sign patterns are formed. The patterns formed in this manner become sign patterns 502-509. Thereby the sign coordinates in each process are managed. From the sign patterns 502-509, coordinates on a chip are specified and observed. As to the defect position on the semiconductor chip, the distance from the sign pattern can be calculated, without scanning the whole part of the chip on the observation visual field. Thereby observation in a short time is enabled, and the efficiency of failure analysis can be improved.

Title: Controller of commutatorless motor
Inventor: OOSAWA HIROSHI
IPC: H02P6/28
Filed: 1983-02-23
Abstract: PURPOSE:To suppress the pulsation of the torque of a DC commutatorless motor having a shunt thyristor by suppressing the current rise or overshoot when the current of the motor is interrupted, thereby alleviating the current capacity and the operating duty of a converter. CONSTITUTION:The output current of a power source side converter 1 is interrupted by a zero current command of a zero current instruction unit 38 at the current interrupting time, a shunt thyristor 5 is turned ON, contacts 42, 44 are opened, an integrating operation is stopped, and a proportional gain is lowered. The zero current command is eliminated by the detection of the zero current by a zero current detector 37, and a firing angle regulator 36 controls the output current of a power source side converter 1 on the basis of the output of a current regulator 40. The output of the regulator 40 at this time point remains low in the gain of a proportional regulator 43 due to the open state of the time extension contact 44. On the other hand, a shunt thyristor 5 is extinguished when the output current of the converter 1 rises to become equal to the circulating current, the time extension contact 44 is reset to the extinguishing time, and the gain of the regulator 43 is returned to the original value.

Title: Electrode plate for lead storage battery
Inventor: SATOU MASASHI
IPC: H01M4/62
Filed: 1982-02-25
Abstract: PURPOSE:To enhance the close contact between long fibers and an active material by heating and kneading an original mixture material which is composed of a conductive resin, a minute powder of a noble metal or an oxide of a noble metal, and a plasticizer, and after that, eluting or extracting the plasticizer so as to give a porosity to the long fibers, being followed by adding the long fibers to a paste. CONSTITUTION:After polyacrylonitrile (30wt%), silver powder (10wt%) and petroleum oil (60wt%) are heated and kneaded with a mixer or the like, the mixture is subjected to extrusion molding so as to obtain long fibers of about 3 denier. Next, a plasticizer contained in the fibers are extracted by ultrasonic waves in a trichloroethylene solution. Thus obtained synthetic fibers are used after being cut into a length of about 1-3mm.. Since thus prepared fibers have irregular surfaces due to the adherence of silver powder, and since an active material enters the fibers due to the porosity of the fibers, the intensity of the active material is considered to be widely increased. As a result, generation of failures caused during assembly of a battery is reduced, the life of the battery is extended by decreasing the separation of the active material, and any defective starting which might be caused by undercharging is prevented.

Abstract: PROBLEM TO BE SOLVED: To obtain a composition having excellent water tree resistance by mixing a crosslinked polyethylene with a poly-N-vinylacetamide in a specified ratio. SOLUTION: There is provided a composition comprising a crosslinked polyethylene and 0.1-10.0 wt.% poly-N-vinylacetamide represented by the formula.

Abstract: PURPOSE:To improve the S/N between input and output signals, to miniaturize the oscillator, to reduce power consumption and to attain high reliability by eliminating the need for any frequency divider circuit between an output frequency and a phase comparator circuit. CONSTITUTION:A voltage controlled oscillating circuit VCO4 is oscillated near a frequency being (m) times of a reference wave input frequency, and when an input signal is applied to a reference wave input terminal 1, the input signal is converted into a pulse having a pulse width being narrow similar to the period of the VCO4 by a pulse converting circuit 7.
