Patent JP-S5839028-A (JP)
Title: Semiconductor device
Inventor: TSUNEKAWA YASUMASA
IPC: H01L21/76
Filed: 1981-09-01
Abstract: PURPOSE:To prevent the parasitic interference between P-N-P transistor and a Darlington transistor by forming a P<+> type base layer which separate P-N-P transistor group from Darlington transistor group. CONSTITUTION:A P<+> type base layer 21 is formed over the peripheral insulating region between P-N-P transistor group and Darlington transistor group. Thus, carrier injected from the P-N-P transistors is collected and flowed through an insulating region to a substrate GND, thereby preventing the carrier from reaching transistors Q31, Q41 and removing parasitic P-N-P structure. When the transistors Q31, Q41 are saturated, an interference may occur between Q31 and Q41, but the P<+> type base layer may be inserted between the Q31 and Q41. The mutual interference can be prevented by isolating the P-N-P transistor group and the Darlington transistor groups via the P<+> type base layer, thereby preventing the erroneous writing. Accordingly, a bipolar PROM which performs the high writing yield can be obtained.

IPC: C02F3/06
Filed: 1989-06-01
Abstract: PURPOSE:To permit org. matter and SS to be treated at a high level by a method wherein a packed layer consisting of granulated packing material is provided at the upper part of a clarification zone of a final sedimentation basin and an air diffusing device is provided at the inner lower part of the packed layer or thereunder. CONSTITUTION:SS at a high settling velocity in sewage water is settled in the course of passage through a final sedimentation basin 1 and the liq. thus separated is passed through a packed layer consisting of granulated packing material provided at the upper part of a clarification zone. Air is moved upwardly into the packed layer uniformly and slowly to provide an aerobic environment in order to form a microbial membrane therein. With the liq. passing through this packed layer, most of easily decomposable org. matter and part of difficultly decomposable matter are removed therefrom and also SS at a low settling velocity is collected for subsequent removal as a purified effluent from this zone. In doing so, org. matter and SS in a secondary process can be treated at a high level.

Title: Jig for measuring minute current of semiconductor device
Inventor: MATSUMURA TAKASHI
IPC: G01R15/12
Filed: 1977-11-17
Abstract: PURPOSE: To produce a jig which is capable of measuring the minute current of a semiconductor device accurately and rapidly.  
     CONSTITUTION: When a semiconductor device 6 is pushed into the sndwiching part 2 of a metal plate cap 1 having spring characteristic, its top face abuts against a stopper, thus the device is surely sandwiched at an accurate depth. A lead terminal 7 of a semiconductor is inserted into a measuring socket and minute current is measued. At this time, the cap 1 is grounded by a lead 5 and therefore the device  6 is perfectly shielded from distrubance noise and since the fingers do not directly  contact the device 6, there is no termperature rise owing to the conduction of body  temperature. In this way, measurement may be made rapidly and accurately.

Abstract: PURPOSE:To enable precise separate detection of two or more airplanes being in proximity on an azimuth plane by a method wherein first and third pulses are emitted in a pattern of the sum respectively, while a second pulse is emitted in a pattern of a difference, and either the emission power of the first and third pulses or the emission power of the second pulse is adjusted. CONSTITUTION:First and third pulses P1 and P2 and a second pulse P2 are generated by first and second transmitters 111 and 112 being independent of each other and they can be subjected to level adjustment discretely by first and second power adjusting devices 113 and 114. When a level difference is given a sum SIGMA pattern and a difference   pattern by this constitution, it is possible to narrow a transponder response area in a SIGMA beam and to narrow a horizontal beam width of the SIGMA pattern equivalently. Thereby horizontal resolution is improved. Even when two or more airplanes are at the same distance from an electronic scan antenna 12 for a monopulse and in proximity to each other within an azimuth plane, therefore, either one of them is removed out of a horizontal beam of the SIGMA pattern and each of the airplanes can be detected separately.

Abstract: PURPOSE:To generate testing conditions equivalent to a conventional combination test of a testing state, the conditions of operation, etc. by unifying a motor- operation mechanism section and a mechanism corresponding to a diverter switch, forming a single-substance test apparatus proper and independently mounting or dismantling a tap changer to or from the test apparatus proper. CONSTITUTION:A tape selector 15 is fitted to a single-substance test apparatus 10. Mounting is conducted in the same manner as the state of the combination of a diverter switch and the tap selector in such a manner that a tie-in section 16 in the lower section of a single-substance test apparatus proper 12 and an upper flange for the tap selector 15 are clamped and fixed. The tie-in size of the upper flange for the tap selector 15 is made sure at that time. Driving force is transmitted over the tap selector 15 to be tested through a torque detecting section 18, a torque transmitting mechanism section 19 and a coupling section 17. Since the torque transmitting mechanism section 19 transmits stable forward and reverse rotation driving-force in the same manner as a mechanism as the content of the diverter switch, conditions equivalent to a combination test can be obtained in addition to the conditions of driving.

Abstract: PURPOSE:To prevent colloidal silica from adhering to the membrane face based on electrostatic repelling force and maintain high transmission flow rate by using a negatively charged membrane as the membrane in concentration treatment of colloidal silica-containing liquid by a membrane separation apparatus. CONSTITUTION:Regarding a membrane separation apparatus to carry out concentration treatment in order to separate silica from a colloidal silica-containing liquid such as wastewater produced by silica wafer grinding and reuse the silica, a negatively charged membrane is used as a membrane. Membranes of organic polyers, for example, polysulfone, polyethersulfone, polyetherketone, polyamide, polyimide, polyolefine, etc., and membranes prepared by introducing negative charge groups such as carboxyl group, sulfonyl group, etc., into an inorganic material such as ceramics, porous glass, etc., are used as the negatively charged membrane. Consequently, due to the same polarity of the charged polarity of colloidal silica as that of the membrane, colloidal silica is prevented from adhering to each membrane face dur to electrostatically repelling force and high flow rate is maintained.
