Title: Radiant tube
Inventor: NAKAMURA MASATOMO
IPC: F23C3/00
Filed: 1981-11-16
Abstract: PURPOSE:To lower the temperature in a heat-treating furnace, and to decrease NOX in  exhaust gas, during combustion, by providing an inner tube which has a gas-permeable  tubular wall, to the inside of a metallic tube, and by forming an annular combustion  chamber in a gap between the tubular wall of an inner tube and the metallic tube, where combustion is taken place dispersedly around the external periphery of a tubular  wall. CONSTITUTION:When a radiant tube 2, provided to a heat-treating furnace by piercing  through a furnace wall 1, 1, is operated, fuel gas is fed into a gas inlet port 12, and  combustion air is fed into an inlet port 6, respectively. The fuel gas, passing through a  gas feed tube 7 and an inner tube 8, is fed into a combustion chamber 13, nearly in the  diametral direction, permeating through a tubular wall 9. On the other hand, the combustion air is fed into the combustion chamber 13 in the axial-flow direction, passing  through an air box 5 and the end part of a metallic tube 3. The combustion air is  mixed with the above-mentioned fuel gas, and is ignited, and then, combustion is started. Combustion can be taken place widely dispersed over the whole area of external  surface of a tubular wall 9, because fuel gas is fed into the combustion chamber 13,  being straightened and dispersed over the full length of an inner tube 8 when it passes through the tubular wall 9.

Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce in size an equalizer circuit, by rotating a plurality of T-shaped polysilicon gate at a specific angle with respect to a bit line, connecting them together, forming a single conductor, rotatably connecting two adjacent T-shaped polysilicon gates, and forming a singe conductor.

While the two gates remain connected at a point as they are, an M-shaped polysilicon gate is formed. Paired equalizer circuit for two adjacent to paired bit lines 102a/102b and 612a/612b can be implemented in size of a reduced X-direction by rotation of the T-shaped polysilicon gates, and the equalizer circuit can also be reduced in size in a Y-direction by using the M-shaped polysilicon gate, thereby reducing in size the circuit.

Filed: 1985-08-22
Abstract: PURPOSE:To set load conditions freely and to transfer the output of an IC to be tested to a comparator faithfully without reference to a test mode by controlling the connection and disconnection of a current load circuit through a relay. CONSTITUTION:The relay 14 is turned OFF in input mode to disconnect a current load circuit 13 and turns ON a selector circuit 9, so that a driver circuit 1 which reacts to a pattern signal from a terminal 7 is connected to the IC 3 to be measured.

Title: Semiconductor light emitting device
Inventor: KIHARA KATSUHIRO
IPC: H01S5/12
Filed: 1988-07-25
Abstract: PURPOSE:To provide the selectivity of a TE wave and a TM wave by transmitting linearly only the TE wave from an active layer to a clad layer at a bent part in a lambda/4 DFB laser, propagating the TM wave toward a bent active layer, and absorbing the TM wave without providing an electrode on the bent active layer. CONSTITUTION:The reflectivity R of a TE wave(Transverse-Electric Wave) is gradually decreased as an incident angle theta is increased, and becomes '0' at a Brewster angle thetaB, is abruptly increased therethrough, and fully reflected at a critical angle thetaC. On the other hand, the reflectivity R of a TM wave(Transverse-Magnetic Wave) is simply gradually increased as the incident angle theta, is abruptly increased through the angle thetaB, and fully reflected at the angle thetaC. Thus, the reflectivity of the TE wave becomes '0' when it is incident at the Brewster angle in the boundary between an active layer 5A and a clad layer 6 to be transmitted. On the other hand, the TM wave is bent toward the bent layer 5A, and since no electrode is provided in this region, no light emission occurs, and the TM wave is absorbed into the active layer. Thus, the TM wave is absorbed in the lambda/4 DFB(distributed feedback type) laser, and can be oscillated only with the TE wave.

Abstract: PURPOSE:To achieve improvement of printing quality by removing deformation of a liquid path in joining substrates by a method where in after forming low melting point glass on one side of joining surfaces of two or three silicon substrates by sputtering or vapor deposition, the joining surfaces are superimposed on one another and are joined by impressing negative voltage to the silicon substrate side on which the low melting point glass is formed. CONSTITUTION:Low melting point glass 5 with a thickness of 1,000 to 10,00Angstrom  is formed on either side of joining surface 4 of a first substrate 2 or a second substrate 3 by a sputtering method or a vapor deposition method. Glass of about 350 deg.C in melting point is used as the low melting point glass 5 and is formed to the second substrate side by the sputtering method. When this first substrate 1 is opposed to the second substrate 3 and 70 V negative voltage is impressed to the second substrate 3 side in a 120 C deg. atmosphere, joining can be performed in short time without passing though a joining process at high temperature. A part of a liquid jet part in which a liquid path 6 is thus formed is cut and a liquid jet surface 7 is formed. Thereafter, a piezoelectric element 8 is adhered onto the second substrate positioning on each liquid path and a liquid jet recording head 9 is obtained.
