Title: Manufacture of semiconductor device
Inventor: MAEGUCHI KENJI
IPC: H01L29/78
Filed: 1985-05-08
Abstract: PURPOSE:To speed up the operation and improve the dielectric strength of a junction by a method wherein a mask material is left on the side wall of an oxidization-resistant film pattern by anisotropic ion etching and impurity ions are implanted into a substrate to form an inversion-preventing high impurity concentration region and an element isolation region is formed by selective oxidization. CONSTITUTION:A silicon nitride film pattern 22 and an oxide film pattern 23 are formed on a P type silicon substrate 21. A CVD SiO2 film 24 is deposited and etched by anisotropic etching so as to remain only on the side wall of the silicon nitride film pattern 22. Then, utilizing the pattern 22 and the remaining film 24 as a mask, boron ions are implanted to form P<+> type field inversion preventing layers 25 and the CVD SiO2 film 24 is removed by etching. By forming field oxide film 26, element regions 27 are isolated from each other. After the oxide film pattern 23 is removed, a gate oxide film 28 is formed and a polycrystalline silicon layer 29 is deposited and patterned to form a gate electrode 30. Utilizing the gate electrode 30 as a mask, ions are implanted into the element region 27 to form N<+> type source and drain regions 31 and 32.

Abstract: PURPOSE:To dissolve a large amt. of oxygen in water by providing an air chamber to between a submergible motor and a hollow shaft, connecting an air communicating pipe to the air chamber, and providing also a communicating hole to a hollow pipe in the air chamber. CONSTITUTION:A negative pressure is generated in the inside of a hollow shaft 2 by the revolution of a blade plate 12b and unillustrated blade plates, and air is ejected from a communicating hole 13 through an air communicating pipe 8, air chamber 5, communicating hole 9, and the inside of the hollow shaft 2. Further, water is introduced from a water inlet hole 23 of a water inlet pipe 24 into a hollow part of the hollow shaft 2 while scattering the water by the effect of the revolution and the negative pressure, and the water is mixed with the air in the hollow part. The water mixed with the air flows out of the communicating hole 13 and stirred by the revolution of the blade plate 12b and the unillustrated blade plates. Thus the air is atomized and mixed with the water. Thus, an area for contacting air with water increases and sufficient contact of air with water is attained, permitting thus dissolution of a large amt. of oxygen in water.

Abstract: PURPOSE:To make it possible to eliminate a rubber protruded part from one side without reversing a wheel and to facilitate elimination work, by forming a small cavity part for escaping excessive rubber to an upper mold and forming the rubber protruded part only to one side of a tire part. CONSTITUTION:An iron wheel 7 is arranged in a lower mold 13L and a rubber lump is inserted in the mold 13L and an upper mold 13H is fallen. Whereupon, the rubber lump is compressed to be flowed in the chambers 17H, 17L of the upper and lower molds 13H, 13L and covers a ring shaped rim 5 and succeedingly covers the outer end part 4 of each spoke 3. The rubber having flowed to the outer end part 4 is apt to flow out through the gap between the spoke 13 and an upper support metal fitting 14H but, because there is the small cavity part A of the upper mold 13H in this side, said rubber enters said small cavity part A to form a protruded part B. Because of this, the rubber protruded part B is always formed only to one side of a wheel.

IPC: B60L11/18
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To reduce the wasteful power consumption and minimize the space occupied by parts by using a hydraulic operating contact as a means for interrupting electric equipment circuit such as lamp having a large power consumption. SOLUTION: When a key switch KS is switched from start state to ON state to supply a power to a control board 12, a hydraulic operating contact exciting coil M6C, etc., is excited by the signal from the control board 12. Consequently, the contact M6 of a hydraulic operating contact is closed to supply a power to a hydraulic circuit, and the power is also supplied to a lamp circuit having a large power consumption through the contact M6 of the hydraulic operating contact. When no operation is performed for a fixed time in this state, the signal from the control board 12 to the hydraulic operating contact exciting coil M6C, etc., is cut, and the contact M6, etc., of the hydraulic operating contact is closed. The power supply to the hydraulic circuit is thus interrupted, and the power to the lamp circuit having the large power consumption is also interrupted.
