Title: Semiconductor device with continuous connection and its production method
Inventor: YAMAZAKI SHIYUNPEI
IPC: H01L31/10
Filed: 1979-06-05
Abstract: PURPOSE: To reduce misalignment of crystal lattice at a hetro juncture for its improvement by changing an energy band.  
     CONSTITUTION: When p type or n type semeconductor is formed by mixing an impurity p, A s or B into non-crystal films of amorphous or multi crystal-structured Si, hologen compounds such as H, F or Cl are attached with a concentration of 2∼200%. They are connected to a non-coupled connecter O to reduce a reconnection-centered occurrence and avoid an electrically neutral (inactive) renotch and a spike. Then with a use of CH 4 , NH 4  and H 2 O, C, N and O are diffused equally and attached to the semiconductor so as not to form a cluster in it. Such continuous change of the energy band can take away the non-coupled connecter inherent due to a lattice disarrangement at the necessary field surface of a hetro connection and can also take away the lattice defect-based field surface semi-position.

IPC: B29C70/06
Filed: 1978-06-12
Abstract: PURPOSE: A mold for reinforced plastic pipes capable of easy mold releasing, comprising axes movable in the radial direction provided in the radial through-holes of the wall of a tubular material, set pieces attached to the inside ends of the axes,  and an outer split cylindrical body consisting of an elastic material.  
     CONSTITUTION: The set pieces 4 and the axes 2 are moved outward by feeding a pressurized fluid, by inserting a bar into a mold, or by expanding an air bag under  pressure from the inside. The split cylindrical body 3 is expanded to enlarge the  diameter of the cylindrical body 5 of an elastic material to a given one. A molding  material, e.g. continuous glass filaments impregnated with a resin, is wrapped  around the body 5 and cured to remove the pressurized fluid, the bar, or the expansion of the air bag. The body 5 is shrunk to the original state due to its elasticity, thus removing the mold from the molded reinforced plastic pipe readily.

Title: Constant flow rate valve device
Inventor: OKAZAKI YOSHIYA
IPC: C02F1/46
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To ensure a free flow as long as fluid pressure on suction side is prescribed value or less, and to maintain fluid flow rate on a discharge side less than a set value when the above fluid pressure rises beyond the prescribed value. SOLUTION: A valve element 9 to seat and leave from a cylindrical upper valve seat 15 is made of a soft material such as rubber or the like. The lower end of the upper valve seat 15 is provided with a constant flow rate opening 16. The upper end flange 16a of the above opening 16 is formed in two-stepped staircase-shape in a peripheral direction. When the fluid flow rate on a suction side attains a set value, the valve element 9 seats on the upper valve seat 15, and the fluid on the suction side passes through the constant flow rate opening 16 and flows toward a discharge side.  When the fluid flow rate on the suction side exceeds the set value, and fluid pressure on the suction side rises, the valve element 9 rises into the constant flow rate opening 16 and deforms there, and when the fluid pressure on the suction side rises above the prescribed value, the substantial opening area of the constant flow rate opening 16 varys. Thus when the fluid pressure on the suction side changes more than the fixed value, the fluid flow rate on the discharge side can be set below the set value.
