Title: Method of fabricating junction field effect transistor
Inventor: YASUOKA HIDEKI
IPC: H01L29/808
Filed: 1978-10-20
Abstract: PURPOSE: To provide a method of fabricating a junction field effect transistor which can simply execute an isolation therein by sequentially forming N-type and N - -type epitaxial layers on the surface of p-type semiconductor substrate and providing source, gate and drain regions of the transistor J-FET on the N - -type epitaxial layer.  
     CONSTITUTION: There are formed N + -type layers 1A, 1B becoming buried layers, further N-type silicon epitaxial layer 2, and P + -type isolation diffusion region 2A on a P-type silicon substrate 1. Then, P-type impurity is diffused selectively with SiO 2  as a mask to thereby provide a P + -type region 3, and N - -type epitaxial layer 4 is then formed in low impurity concentration on the layer 2. P-type impurity is selected and diffused from N - -type surface corresponding to the periphery of the region 3 to thereby provide an isolation region 5 and simultaneously form P + -type isolation region reaching the region 2A by diffusion process. P-type and N-type impurities are selectively diffused in N - -type islant domain 6 fabricated by the regions 3 and 5 to thereby form P + -type gate region 7, N + -type source region 8 and N + -type drain region 9 to thus form N-channel junction field effect transistor J-FET.

Title: Water area purifying equipment
Inventor: MATSUMOTO YUKIHISA
IPC: B63B35/00
Filed: 1993-04-30
Abstract: PURPOSE:To feed water passing through an aeration tank into the water bottom as pumping power is saved in a water area purifying equipment which aerates water just under the surface of water in a water area and feeds it into the water bottom, and to increase the structural strength of the whole of the equipment. CONSTITUTION:An aeration tank 3 is attached to the suction part of a conveying pump 2 just under the surface of water 20, and the water passing through the aeration tank 3 passes through a rigid conveying pipe 1 which is connected to a pump discharging part and extends downward, and is horizontally discharged from a discharging port 14 near the water bottom. The lower end of the rigid conveying pipe 1 is restrained at the water bottom 21. Thus, since a short rigid conveying pipe 1 is used instead of an usual long flexible hose, pressure loss in the conveying pipe 1 can be reduced for saving pumping, power and increasing the structural strength of purifying equipment.

Filed: 1979-10-04
Abstract: PURPOSE: To obtain a predicting method of ignition prediction with high precision by detecting the recovery phenomenon of electric resistance occurring in the process of insulation deterioration by applying a voltage between a couple of counter electrodes provided on an organic insulating material.  
     CONSTITUTION: On organic insulating material 1, a couple of counter electrodes 2 and 2' are proved and a voltage is applied between both. As leakage current signal (a) sent to current comparator 6 exceeds a prescribed magnitude value, relay 7 is put into operation with a signal from current comparator 6 to close normally opened relay contact 7'. Then, recovery frequency display counter 8, which can be preset, for a resistance is operated to count a frequency in change exceeding the prescribed value of leakage current and when this operation is repeated until a preset frequency, alarm 9 operates to announce a damger of fire. Thus, the ignition due to electric leakage can be predicted with high precision by detecting the recovery phenomenon of the surface resistance of the insulating material.

Title: Automatic ultrasonic bonder
Inventor: OSABE HIROSHI
IPC: H01L21/607
Filed: 1979-10-05
Abstract: PURPOSE:To permit the snapping of a wire to be reliably detected by allowing a detector to detect the revolution of the roller rotating by the tensile force of the wire. CONSTITUTION:By the bonding operation, a wire 1 is passed through a detecting roller 8 and pressure roller 9, pulled out in the direction of an arrow 11, and ultrasonically bonded on the surface of an IC 7 mounted in a ceramic case 6. On doing this, the roller 8 is rotated by the tensile force of the wire 1. The rotation is detected by a detector 10 not contacting with the roller 8 to know whether or not the bonding is normally performed, that is, whether or not the wire is broken. When the wire snaps, the rotation of the roller 8 stops and no detection output is provided from the detector 10. This stops the bonding operation automatically. Thus, properly selecting the roller distortion, slit distance, pressure and the like permits the snapping of the wire to be reliably detected.
