Title: Porous tungsten sintered substance
Inventor: FUKUHARA YOSHIO
IPC: H01J1/28
Filed: 1982-12-08
Abstract: PURPOSE:To obtain a porous tungsten sintered substance having high heat-resistance and the relatively big surface area by using tungsten powder having the specific grain size for heightening the mechanical strength in order to get the specific value of density. CONSTITUTION:The mechanical strength of a sintered substance is requid to be heightened for obtaining the heat-resistance of a porous sintered substance W, while the mechanical strength can be heightened by heightening the density of the sintered substance and lessening the grain size and a bore. On the other hand, the density of the sintered substance is required to be lowered while decreasing the closed bore and increasing the opened bore in order to obtain the sintered substance having a wide surface area. In consideration thereof, the density of the sintered substance is made to be 15.50-17.00g/cm<2> while the average grain size of the W powder is regurated to be 3-10mu. Thereby, the sintered substance having high heat-resistance and a wide surface area can be obtained.

IPC: F22B37/22
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of the break of a furnace wall by deformation, and cracks at the welded joints between a side plate and a wall mounting member, and between the furnace wall and the wall mounting member caused by the difference of thermal expansion between the furnace wall and a header. SOLUTION: This supporting unit fixes a pair of side plates 14 supporting the both ends of a header 2 vertically to a supporting member 13. The wall- mounting member 10 supports the sup-porting member 13 through a pin 12. The header 2 is supported by the side plates horizontally and movably. When the difference of thermal expansion is generated between the furnace wall 1 and the header 2, the supporting member 13 rotates around the axis of the pin 12 and the generation of the bending moment between the furnace wall 1 and the header 2 can be prevented.

Title: Semiconductor optical control device
Inventor: KOMATSU YOSHIRO
IPC: G02B6/122
Filed: 1992-08-11
Abstract: PURPOSE:To provide a waveguide type semiconductor optical control device of an InP type which has a small' angle of radiation to incident and exit light and a low-loss connection with a single-mode fiber. CONSTITUTION:On an InP substrate 101, an n-InGaAsP clad layer 102 (lambdag=1, 15mum), an i-InGaAsP absorbing layer 103 (lambdag=1, 45mum), an i-InGaAsP clad layer 104 (lambdag=1, 15mum), and an i-InP clad layer 105 are formed. Further, a stripe-shape p-InP clad layer 106 and a p-InGaAs cap layer 107 are formed on top. Because the clad layers 102 and 104 are of InGaAsP mixed crystals, no loss of a wavelength of waveguide light occurs in the clad layer. In addition, a difference of refractive index between the light absorbing layer 103 and the clad layer can be made small to lower an angle of radiation. Consequently, a coupled loss of a InP type waveguide light control device and a single mode fiber can be diminished.
