Title: Semiconductor device
Inventor: MAKIUCHI MASAO
IPC: H01L27/14
Filed: 1990-11-30
Abstract: PURPOSE:To enable a positive electrode and a negative electrode to be created on the same plane and a light-receiving element to be highly efficient by laminating a first conductive type carrier supply layer and a light-absorbing layer on a substrate in sequence and then forming an electrode region with a second conductive type large and small areas on them. CONSTITUTION:A carrier supply layer 3 with a wide band gap and a first conductive type impurities density and a light-absorption layer 4 with a narrow band gap and a low impurities density where a large part of a thickness can easily result in depletion are formed on a substrate and then at least two electrode regions 6 and 7 with a second conductive type impurities density and large and small areas are formed on it. A region below the large-area electrode region is biased in backward direction and that below a small-area electrode region is biased in forward direction. At this time, a two-dimensional carrier gas 10 is formed near an interface between the light- absorption layer 4 and a carrier supply layer 3 and a carrier gas is drawn below an electrode where a forward bias is applied to, thus forming a connection with a low resistance in reference to the electrode. Therefore, p-side and n-side electrodes are connected to both edges of a region where a depletion layer is developed at a low resistance, thus achieving a high response.

Title: Method for testing ac dielectric breakdown of power cable
Inventor: SANO KENJI
IPC: G01N27/92
Filed: 1989-12-29
Abstract: PURPOSE:To easily and certainly discover a dielectric breakdown hole by applying AC voltage across a lead and a shield body to generate dielectric breakdown in an insulating body and instantaneously stopping the application of the voltage to form the dielectric breakdown hole in the insulating body. CONSTITUTION:AC voltage is applied across the conductor 11 and shield body 15 of a CV cable 10 to generate dielectric breakdown in an insulating body 13 and the application of the voltage is instantaneously stopped to form a fine dielectric breakdown hole 18 in the insulating body 13 while the state before dielectric breakdown is preserved as much as possible as it is. Next, water 57 being a non-insulating liquid is introduced between the conductor 11 and insulating body of the cable 10 under pressure. The cable 10 whose breakdown hole 18 is filled with the water 57 by this method is cut into two parts and the respective parts are subjected to a megger test. The cut part having the breakdown hole 18 formed thereto lowers in insulation resistance but the other healthy cut part does not lower in insulation resistance. Further, by successively repeating the cutting of the cable and the megger test, the position of the breakdown hole 18 is roughly estimated.

Title: Positioning device of vessel of nondestructive inspection apparatus
Inventor: ITO YASUSHI
IPC: G01N1/28
Filed: 1991-12-24
Abstract: PURPOSE:To improve measuring precision of nondestructive inspection. CONSTITUTION:A packed vessel 5 is put on a measuring stage 4. A pressing member 2 being advanced subsequently, the packed vessel 5 is thereby pushed in the direction of a support block 3 for positioning the vessel, brought into contact with the support block 3 and positioned at a prescribed position on the measuring stage 4. Although the packed vessel 5 is subjected to frictional resistances from the measuring stage 4, the support block 3 for positioning the vessel and the pressing member 2 on the occasion, the frictional resistances are very small, since the areas of contact of these parts with the packed vessel 5 are small and since rails made of a material of which the frictional resistance with the packed vessel 5 is small are provided for the measuring stage 4, the support block 3 and the pressing member 2 respectively, and therefore the packed vessel 5 is positioned correctly at the prescribed position on the measuring stage 4 without losing an expected attitude, even with a small pressing force of the pressing member 2. Since the pressing force of the pressing member 2 is small, besides, any abnormal change in the shape of the packed vessel 5 does not occur, and measuring precision is improved.

Title: Fuel injection quantity control device for internal combustion engine
Inventor: NAKAJIMA TATSUSHI
IPC: F02D41/40
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To provide an engine rotating speed capable of catching an inlet air quantity in the calculation of fuel injection quantity, and prevent the generation of black smoke in acceleration transient period. SOLUTION: A rotating speed calculating means M2 determines one explosion period where one explosion by an optional cylinder of an engine M1 is necessarily generated by equally dividing the rotating angle of an output shaft in one cycle of the engine M1 by the number of cylinders of the engine M1, and calculates the rotating speed of the engine M1 for this explosion period. At that time, the rotating speed for one explosion period is determined as followed by the inlet air rotating speed calculating means M5 of the rotating speed calculating means M2. Namely, the means M5 preliminarily stores the timing where the optional cylinder starts and ends intake stroke, and the rotating speed in the intake stroke period is used to the calculation of the injection quantity capable of being supplied to the engine.  Thus, the intake quantity highly correlative to smoke generating quantity can be caught from the rotating speed in intake stroke, and the generation of smoke can be limited.

Title: Nickel hydrogen square battery
Inventor: KAWASE YASUSHI
IPC: H01M4/32
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To reduce electric resistance of an electrode, and reduce heating at large current discharging by setting the thickness of a horizontal lead part not less than a half of a clearance in an upper end part of a current collecting body before an electrode plate is housed in a battery jar, and thickening the horizontal lead part in an allowable range. SOLUTION: The sum of the thicknesses of a pair of a positive electrode 6 and a negative electrode 7 containing an active material 1 is denoted by To, and the thickness of the whole horizontal lead part 30 is denoted by (t), and the thickness of an upper end part of foaming nickel soaked under pressure is denoted by (top), and the thickness of punching metal is denoted by (ton). Here, when 2t exceeds 0.8 to 1.0 time (To-top-ton), the cycle service life reduces. On the other hand, even if 2t is less 0.3 to 0.5 time (To-top-ton), the cycle service life reduces. When the thickness of the horizontal lead part 30 is set within the range, a sudden reduction in the cycle service life caused by the damage of a separator 8 can be prevented. The electric current distribution with every electrode becomes uniform by an increase in a thickness of the horizontal lead part 30, and local overcharging and overdischarging can be prevented.
