Title: Method for measuring withstand voltage of semiconductor device
Inventor: MORI MASAMICHI
IPC: G01R31/26
Filed: 1988-06-16
Abstract: PURPOSE:To measure withstand voltage with high accuracy by connecting one terminal of a semiconductor device to a voltage source controlled in voltage by a CPU through a high resistor. CONSTITUTION:A semiconductor device 21 is connected to a voltage source 23 through a high DC resistor 22 (or ammeter 24). A CPU 26 reads the current value of the ammeter 24 and controls the voltage source 23 to calculate withstand voltage. A stack memory 27 stores a set voltage value V generated during measuring operation and the measured current value I at said voltage. By this method, when the current value I is equal to or more than a prescribed current value I1 and a voltage increment is a prescribed measured value or less, measuring operation is stopped to calculate withstand voltage from a predetermined formula. When the current value I is equal to or more than the current value I1, the value nearest to the current value I1 is selected from the combination of the past voltage value V and current value I stored in the memory 27 to calculate withstand voltage according to a predetermined formula. When the voltage increment is larger than prescribed measuring resolving power though the current value I is equal to or more than the current value I1, the voltage value V is returned to the value at the time of the previous measurement and the voltage increment at that time is reduced at a certain contraction rate before measuring operation is repeated.

Title: Brake preferential accelerator unit
Inventor: WATANABE MAMORU
IPC: B60W10/18
Filed: 1978-11-30
Abstract: PURPOSE: To preferentially operate a brake to an accelerator unit by dividing a servo motor into low and high gas pressure chambers via a diaphragm, communicating the low and high gas pressure chambers with the low and high gas pressure chambers, respectively of a brake servo motor and providing a gas pressure difference responsive member and a control spring in the low gas pressure chamber.  
     CONSTITUTION: When an accelerator pedal 5 is depressed, an accelerator rod 6 is moved in the direction of an arrow to allow a gas pressure difference responsive member 7 and a connecting rod 9 to be moved through a control spring 13 in the same direction to thereby open a throttle valve 11. When a brake pedal 16 is depressed in this state, the high gas pressure chamber 18 of a servo motor 15 becomes atmospheric pressure to thereby cause the high gas pressure chamber 4 of an accelerator unit 1 to become the atmospheric pressure. Thus, there occurs gas pressure difference btween the high and the low gas pressure chambers 4 and 3, and a diaphragm 2 accordingly urges the member 7 in the direction for closing the throttle valve while compressing the spring 13. Accordingly, the throttle valve 11 is closed. Thus, the brake is preferentially operated when the accelerator and brake pedals are simultaneously depressed.

Filed: 1991-06-19
Abstract: PURPOSE:To improve assembling precision by making it possible to fix a magnetic head after assembling a core to be a fitting standard. CONSTITUTION:At the time of the assembling of a head driving device, the magnetic head 1 and a head supporting plate 2 are fixed to each other, and the supporting plate 2 and a coil bobbin 5 are fixed temporarily to each other, and components except a magnet 7b and the core 6e are assembled. The reference plane of the core 6c is fixed, and the head 1 is fixed while its inclination is watched, and is fixed to the bobbin 5 through the hole of the core 6c. After that, the fixed assembly of the magnet 7b and the core 6e is fixed to the core 6c. Thus, since the head 1 can be fixed after the core 6c of the fitting standard is assembled, the assembling precision is improved, and since a material other than a spring can be selected for the head supporting plate 2, resonance frequency jointed with the supporting plate can be changed, and in the case of a combination head, the inclining of the heads to each other can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To dispense with a leading part by forming a first external terminal electrode to be connected to a first internal electrode layer on the inner wall of one recessed part and a second external terminal electrode to be connected to a second internal electrode layer on the inner wall of the other recessed part respectively. SOLUTION: Recessed parts 11 and 12 extending in the thickness direction of a laminated body 10 are formed at both corners of one end side of the laminated body 10. Then a first external terminal electrode 3 connected to plurality of corners of a first internal electrode layer 13 is formed on the inner wall of the recessed part 11. Further, a second external terminal electrode 4 connected to a plurality of corners of a second internal electrode 14 is formed on the inner wall of the recessed part 12. The recessed parts 11 and 12 provided at the corners of the internal electrode layers 13 and 14 connect practically the internal electrode layers 13 and 14 with the external terminal electrodes 3 and 4.  Thus, the distance between the external terminal electrodes 3 and 4 becomes smaller than the short side of the laminated body 10, reducing inductance therebetween and further reducing inductance of a capacitor.

Title: Mold sand heater
Inventor: FURUI YUUSUKE
IPC: B22C1/00
Filed: 1978-11-29
Abstract: PURPOSE: To evenly heat molding sand and flow and agitate the sand by letting the flow plate segmenting the inside of the furnace above and below to a mold sand heating chamber and a combustion chamber to be inclined to permit easy flowing down of the mold and providing combustion gas feed nozzles with flow control valve to the flow plate.  
     CONSTITUTION: In the shell mold coated sand production process, molding sand is charged onto the flow plate 7 in a vertical barrel type furnace 1 through a sand inlet 20. When combustion gas is sent into a combustion chamber 2, the combustion gas passes through multiple nozzles 8 to above the flow plate 7 evenly over the entire part of its section, thereby agitating the sand while evenly heating the same. Saving of energy is achieved by this gas flow agitation and lack of any moving part obviates the occurrence of any trouble. The dust in the sand flies to the upper part in the furnace and the sand is purified and the dust is collected in a dust collector 16. When the molding sand is heated to the necessary temperature, an output 9 is opened and is taken out to outside the furnace. Since the flow plate 7 is held tilted at an angle of repose or more, the sand goes toward the outlet 9 owing to gravity fall.
