Title: Filter attached pump for molten metal
Inventor: RUTOFUI EICHI AMURA
IPC: F27D27/00
Filed: 1990-02-09
Abstract: PURPOSE: To enable a desired positioning to a pump in a molten metal vessel and to resolve such problem as thermal gradient, etc., at the front and the back of a filter by integrally fixing the filter forming a cavity in a base member having a fluid inlet of the pump.  
     CONSTITUTION: The filter 30 forming the cavity 36 at the gap of a base member 14 is fixed to a shoulder part 28 of the base member 14 surrounding the fluid inlet formed with a impeller 16 of the base member 14 for the pump 10. By this constitution, since the filter 30 is integrated with the member 14, the pump 10 can execute the desired positioning in the molten metal vessel, and since the filter 30 is fully dipped into the molten metal, the heat is not transferred to out of the bath. Further, the existence of the thermal gradient in the molten metal at the front and the back of the filter 30 can be restrained. Then, the filter 30 is made of a sintered refractory material and/or formed as a cup-state structure having a side wall 32 closed with an end wall 34, and the filter 30 is desirable to fit to this member 14 by stick-combining with the end wall 34 and the side wall 32 end part at the reverse side.

Title: Method for gaas liquid phase epitaxial growth
Inventor: MATSUMOTO FUMIO
IPC: H01L21/208
Filed: 1979-03-16
Abstract: PURPOSE:To obtain a flat GaAs layer with low specific resistance on a GaAs substrate by keeping Te quantity in Ga solution at 0.3mol% or more. CONSTITUTION:The quantity in Ga solution which is limited at 0.1mol% or below conventionally is allowed to stand at 0.3mol% or more. A crystal nucleus is then generated evenly covering overall main surface of GaAs substrate and a growth layer grows around the crystal nucleus, therefore an influence of diffusion of Ga solution which is exerted on a liquid phase epitaxial growth rate is decreased relatively, and the growth rate is governed by the nucleus. A projecting abnormal growth is thus kept from occurring on the circumference of the substrate, and a growth at the center of the substrate is accelerated, therefore a yield of growth is sharply improved. In case a carbon board is used, a solution tank can be moved smoothly from the substrate without prejudicing the growth layer finished already.

Title: Method for adhering and fixing cover glass for wrist watch
Inventor: HIRANO MAKOTO
IPC: G04B39/02
Filed: 1989-02-10
Abstract: PURPOSE:To impart a compressive stress to a glass adhering part and to improve adhesive strength by coating the cover glass with an adhesive agent, setting the same, and then irradiating a wrist watch case with UV rays while the case is held heated to cure the adhesive agent. CONSTITUTION:The UV curing type adhesive agent of an acrylic system is put into an injector and is applied to the glass adhering part of the wrist watch case 3 made of a stainless steel, then the cover glass 1 is mounted to the case. The case 3 is then irradiated with IR rays and is thereby heated to about 80 deg.C. Since the case 3 has the large coefft. of thermal expansion than the glass 1, the expansion thereof is large and the thickness t2 of the adhesive layer spreads from the initial state t1. The adhesive layer is immediately irradiated with the UV rays from a high-pressure mercury lamp for one minute in 50cm distance to cure the adhesive agent and to form the adhesive layer 2. The case 3 has the larger shrinkage than the glass 1 and the thickness t2 is larger than the t1 and, therefore, the glass 1 is tightened by the case 3 and the thickness t3 becomes smaller than t2 when the ordinary temp. is restored. The central part of the glass 1 deflects to a projecting shape. The disengagement of the glass and other defects are prevented in such a manner.

Title: Flow rate measuring apparatus
Inventor: OONUKI KOUJI
IPC: G01F1/00
Filed: 1978-03-20
Abstract: PURPOSE: To enable the flow rates within double pipes having intricate channels like the neutron absorber protection pipes of reactor control rods by simply combining  a manometer, flowmeter, flow regulating valve and blind plug.  
     CONSTITUTION: The relation between flow rate Q and pressure loss ΔP between pressure taps is measured with respect to a certain one point in the vertical movement stroke of an absorber protecting pipe 1. The flow rate Q is selected at several points from O up to maximum flow rate QT by regulating a flow regulating valve 12 and is read with a flowmeter 11. At the same time, the pressure loss ΔP between taps is read and the measured values are plotted. The measurement is repeated by changing the flow rate Q and the plots at several points are connected by a curve to make the ΔP-QT curve. Next, a blind plug 15 is provided at the cooling material outlet and inlet of the absorber protecting pipe 1 to close the channel. In this state the flow rate is measured at the same several points when there were no blind plugs are measured and the flow rate QO at which the pressure loss ΔP' between taps becomes equal to the previously measured value ΔP is measured as a paramenter and the ΔP'-QO curve is made. As a result, it becomes QT = QO + Q i  where ΔP = ΔP'. (Q i  is the flow rate in the absorber protecting pipe 1.) Hence, if QT is determined, the flow rate in the absorber protection pipe 1 is immediately known.
