Title: Diffusion of si into compound semiconductor
Inventor: MURAKAMI TAKASHI
IPC: H01L21/225
Filed: 1987-11-04
Abstract: PURPOSE:To facilitate controlling an Si diffusion depth into a compound semiconductor with good reproducibility and precisely by a method wherein a diffusion stopper layer with a composition which has a slower diffusion speed of Si than the compound semiconductor is provided at a predetermined diffusion depth position and then Si is diffused. CONSTITUTION:An AlyGa1-yAs (x<y) diffusion stopper layer 4 which has a slower Si diffusion speed than an AlxGa1-xAs layer 1 is provided at a predetermined diffusion depth position. When the diffusion depth is predetermined as 2.3mum, if the diffusion stopper layer 4 is provided at the position a little shallower than 2.3mum, for instance at the depth of 2.0mum, with a thickness of 0.3mum, the diffusion can be stopped near the diffusion stopper layer 4 easily. In other words, even if the thickness of an Si film 2, an arsenic pressure and a diffusion temperature are varied a little, the diffusion of the predetermined depth can be achieved within a small error by making a diffusion time a little longer than usual. Also for InGaAs system and AlGaInP system compound semiconductors, the same effect can be obtained by employing a slow diffusion speed layer in which the mixed crystal composition is changed as a diffusion stopper layer.

Inventor: MITSUMURA NORIHEI
IPC: C08L23/12
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To eliminate a deterioration in a surface appearance caused by repeating frictions of cloth, paper or the like in a cleaning operation by forming it of a propylene polymer containing a specific amount of a crystal nucleator and specifying a crystallinity of surface layer measured by a reflection X-ray diffraction method. SOLUTION: A crystallinity of an injection molding surface layer obtained by a reflection X-ray diffraction method is set to 60% or more. To this end, it is necessary to add 0.05 to 5 pts.wt. of a crystal nucleator to a propylene polymer. As the nucleator, particularly, it is most suitable to improve a scuff resistance by using Al-p-t-butylbenzoate, 2,2'-methyl-bis(4,6-di-t-butylphenyl)metal phosphate or the like. A polysiloxane is blended with the polymer to obtain the injection molding further improving its scuff resistance. A blending ratio of the polysiloxane is more preferably 0.5 to 5 wt.%.

Abstract: PROBLEM TO BE SOLVED: To improve the lubrication and sealing qualities of the sliding portions of scroll compression elements by providing an oil through-hole in the terminal edge of the end plate of the fixed scroll, and to supply a lubricating oil to the sliding portion of the scroll compression elements through this hole. SOLUTION: When a horizontal scroll compressor 20 is operating, the refrigerant gas is compressed by a scroll compression element 23 through an intake pipe 36, and is discharged into a sealed container 21 through a discharge port 37 of a fixed scroll 33. The discharged gas flows through a conduit provided in the fixed scroll 33 and a support frame 27, and reaches an electromotive element 22. Then the lubricating oil in the refrigerant gas is separated by the centrifugal force of the rotation of a rotor 25, onto a stator 24, a subsidiary support frame 41, and other elements. The separated lubricating oil accumulates in the bottom of the sealed container 21, and is recirculated. For recirculation, a lubricating oil b is drawn up through an oil induction pipe 39 of an oil supply section 38, and is supplied under high pressure through an oil conduit provided inside a rotational axis 26.  This oil both lubricates all the sliding portions including rotational axis 26 and axis bearing 28, and provides a gas seal.
