Abstract: PURPOSE:To prevent carrier in a superlattice multiplying region from staying by providing a chirp superlattice in the part of a potential barrier transferred from a well region to a barrier region, and gradually varying a band structure from the well region to the barrier region. CONSTITUTION:A superlattice multiplying region 10 for multiplying carrier is formed on a light absorption region 3, and a plurality of laminated structures of a well region 5, a chirp superlattice region 7, and a barrier region 9 are superposed in a direction separated from the region 3. An effective band structure is gradually varied in the region 7. For example, a chirp superlattice is formed of the substance A of the region 9 and the substance B of the region 5, a layer A is thinned and a layer B is thickened in a part adjacent to the region 5, the layer A is thickened and the layer B is thinned in a part adjacent to the region 9, and its intermediate is gradually varied. Then, a distribution of an effective band structure which is gradually varied from a band structure near B to a band structure near A is obtained. Thus, even if a composition gradient layer is not used, the carrier can be prevented from staying.

Title: Exhaust gas economizer using air as heat medium
Inventor: SHIGA TAKEMARO
IPC: F02G5/02
Filed: 1979-06-02
Abstract: PURPOSE: To prevent accumulation of soot and corrosion of primary and secondary heat exchangers by means that air heated by exhaust gas in a primary heat exchangr heats in the secondary heat exchanger heat medium, which becomes hot and is supplied to a heat demanding equipment.  
     CONSTITUTION: After exhaust gas discharged from a supercharger 2 of a diesel engine passes through an exhaust pipe 3 and heats air in a primary heat exchanger 4, exhaust gas is released into a funnel 5. Excess exhaust gas runs through a bypass duct 26 via a flow control valve 27 to bypass the heat exchanger 4. The hot air appearing in the primary heat exchanger 4 is carried through a duct 8 into a secondary heat exchanger 9, where the hot air heats water sent by a pump 14. After hot water coming out of the secondary heat exchanger 9 heats medium in a heat demanding equipment 17, the hot medium is led by a duct 18 into an observation tank 19 to inspect the presence of oil. The hot air coming out of the secondary heat exchanger 9 is fed back into the primary heat exchanger 4 via duct 10, thermo- control valve 11 and blower 6.

Title: Casting method of casting having no deposition and inclusion of scum
Inventor: HARA SADAO
IPC: B22C3/00
Filed: 1979-06-05
Abstract: PURPOSE: To prevent the deposition and inclusion of scum on and into coating surface by coating the inside surface of the mold in contact with molten metal by volatile metal such as Zn or Ca or compound which becomes vapor by high-temperature decomposition.  
     CONSTITUTION: Volatile metal such as Zn, Ca or Mg or compound which becomes vapor by high-temperature composition (for example, Ca 3 N 2 , Mg 3 N 2 ) is coated on the inside surface of a sand mold 2 to form a surface coating material 1. Molten metal poured through an injection port 5 passes through cross gate 6, rises from the bottom of the mold and contacts the surface coating material 1. At this contacted time, the surface coating material becomes vapor after melting or decomposing, thereby flying the sucm 4 deposited on the mold surface. Hence, the deposition of scum on casting surface and the occurrence of sand flaws owing to scum inclusion are prevented.

Title: Supplying of fluid to extruding device and extruding device equipped with fluid supplying means
Inventor: YAMAMOTO SHOJI
IPC: B29C48/38
Filed: 1985-04-02
Abstract: PURPOSE:To enable to smoothly supply fluid without being influenced by the internal pressure by a method wherein the pressure at some portion in a flow passage, through which the extrusion material from an extruder is supplied, is made lower than that on the material extrusion port side and the fluid is supplied to said flow passage portion under reduced pressure. CONSTITUTION:Because the higher pressure ahead of a material extrusion port 3 is isolated by a gear pump 15, the pressure in a flow passage portion 14A lying between the inlet 20 of the gear pump 15 and the outlet 1A of an extruder 1 is made variable by properly setting the rotational frequency of the gear pump 15. The extrusion material discharged from the extruder 1 is sucked out by the gear pump 15 and supplied to a crosshead 2. In this case, it is necessary to supply enough amount of extrusion material to the inlet 20 side of the gear pump 15. When the supply of extrusion material to the inlet 20 side of the gear pump 15 is enough, the delivery on the outlet 21 side of the gear pump 15 becomes constant in volume regardless of the viscosity of the extrusion material.
