Title: Manufacture of semiconductor laser
Inventor: FURUMIYA SATOSHI
IPC: H01S5/227
Filed: 1980-04-30
Abstract: PURPOSE:To obtain a semiconductor laser of excellent heat-radiating efficiency by a method wherein a clad layer, an active layer and a clad layer are piled up one upon another on a semiconductor substrate and etched to form a mesa line, and a clad layer is epitaxially formed around the mesa line in order to bury the same. CONSTITUTION:On an N type InP substrate 1, an N type InP 2, an N type InGaAsP active layer 3 and a P type InP 4 are epitaxially formed. An SiO2 mask 7 is provided thereon to perform an anisotropic etching to form a mesa line 6'. Then, a P type InP 8 and an N type InP 9 are continuously epitaxially formed to bury the mesa line 6'. After the mask 7 has been removed, a P type InGaAs connecting layer 14 is epitaxially formed. Consequently, the slightly concave portion 12 remote from the mesa line is absorbed into the layer 14, so that a flat surface is formed. Then, said surface is coated with an Au-Zn alloy to form an electrode 11, while the back surface of the substrate 1 is coated with an Au-Sn alloy to form an electrode 13. The substrate is formed into a chip and secured to a heat sink through an In solder in an upside down manner to obtain a laser which has fewer possibilities of breakage and is excellent in the heat radiating efficiency.

Title: Vibrationproof device and its manufacture
Inventor: ORIKAWA MICHIHIRO
IPC: F16F13/14
Filed: 1990-03-08
Abstract: PURPOSE:To get great attenuation even in low frequency vibration and prevent the rise in internal pressure at high frequency vibration by providing plural liquid chambers filled with liquid inside the elastic body interposed between an inner tube and a middle tube, and connecting the liquid chambers by communication passages. CONSTITUTION:When low frequency large amplitude vibration is transmitted to an inner tube 12 or an outer tube 14, the communication passages connecting plural liquid chambers 30 are blocked by vibration members 28. Therefore, the liquid filled in the plural chambers 30 goes and comes between each other's liquid chambers 30 through a limiting passage. By the passage resistance of the liquid at this time, low frequency large amplitude vibration is attenuated. Furthermore, the limiting passage is made at the periphery of the middle tube 18, so the length of the limiting passage is long and the passage resistance of the liquid is great. As a result, great attenuation can be gotten. Moreover, when high frequency small amplitude vibration is transmitted to the inner tube or the outer tube, the limiting passage gets in the clogged condition, and the liquid does not pass the limiting passage. At this time, the vibration member vibrates inresponse to the increase/decrease of the internal pressure of the liquid chamber and suppresses the internal pressure of the liquid chamber.

Title: Scum foam eliminating method
Inventor: TAGUCHI KENJI
IPC: C02F3/12
Filed: 1978-05-17
Abstract: PURPOSE: To provide an automatic and effective scum eliminating method for blend fluid that flows from aeration tank to settling basin by shrinkaging and destroying scums having larger foam strength after expanding and exploding weak scums.  
     CONSTITUTION: Scum that is developed in the aeration tank 3  stays on the blend fluid surface in a scum chamber 11 flowing through an upper stream submerged weir 5 a. When the fluid surface is covered with scums, control timer sends a singal to close air valve 9 and activate vacuum pump 7 that drains air in air reservoir out of scum chamber through exhaust tube 8. This causes lower external scum pressure than scum inside pressure to expand and explode scums having smaller air foam strength. Then vacuum pump 7 is brought to stop and air valve 9 is opened, which causes an abrupt flow of air into air reservoir 12 through air tube 10. Thus increased scum external pressure immediately compresses and destroyes expanded scums having larger scum strength.
