Title: Manufacture of semiconductor light emitting device
Inventor: IKEDA TOSHIYUKI
IPC: H01S5/00
Filed: 1988-05-24
Abstract: PURPOSE:To improve the yield of manufacturing, by making the sectional shapes of stripe masks for etching arranged on a lamination structure a protruding type, eliminating, by etching, the side end-portions of a mask forming an eaves- type for mesa stripe, and growing buried layers in the state where the mask is left on the mesa stripe. CONSTITUTION:Stripe masks 22, 23 formed on a lamination structure 10 are used as etching masks, whose sectional shape is made a protruding type. By wet etching, the side end-portions of the mask 22 are eliminated with etching liquid, so as to form an eaves-type for a mesa stripe 11. Then buried layers 5, 6 are grown, in the state where the masks 22, 23 are left on the mesa stripe 11. Since the sectional shape of the stripe mask is a protruding type, the side end-portions forming an eaves-type become relatively thin, and are primarily eliminated. Thereby, the buried layers are surely grown, and the yield of manufacturing is improved.

Title: Method and device for removing interference component of periodic signal and application on electronic capacity transformer thereof
Inventor: KURISUTOFU BODAARU
IPC: G01R15/06
Filed: 1995-05-25
Abstract: PURPOSE: To eliminate disturbing component generated in a circuit using a shielded equipment whose disturbing component is exponential function type and has a small time constant by making signal measurement at least two times at two different instants, calculating the parameters of the disburbing component from the result of this measurement and subtracting the disturbing component from the signal. CONSTITUTION: An estimation device of the parameters of exponential component works by means of voltage detection at the time of restart of the device. At the time of restart, the output signal u (t) at the terminal of a low voltage capacitor Cb is in the form of u (t)=Acos (ωt+ψ)+Bexp (-t/τ). Acos (ωt+ψ) expresses an effective component of the signal and Bexp (-t/τ) stands for a disturbing component. If the signal u (t) is measured at two instants t1, t1 +π/ω, equation I is obtained. By adding these equations term by term, equation II is obtained, and the coefficient B is equal to equation III. When B is found, the characteristics of the disturbance are clarified.  Namely, by means of clarified B, the signal Bexp (-t/τ) to be eliminated from the received signal u (t) is found, and as a result, the correction signal for the disturbing exponential component is obtained.

Title: Injection molding method and pressure compensated flow control valve
Inventor: HASHIMOTO TSUTOMU
IPC: B29C45/00
Filed: 1978-10-20
Abstract: PURPOSE:To prevent dispersion from arising on the dimension of moldings at each shot and thus to improve surface appearance and quality by using a pressure compensated flow control valve provided in oil hydraulic circuit of an injection molding machine selectively to operation or non-operation. CONSTITUTION:A bolt 10 to work as a stopper for adjusting a spring 6 is mounted coaxially with a pressure compensating valve 5 on a flow control body 1 provided in oil hydraulic circuit of an injection molding machine. In case a high injection speed is required, the bolt 10 is screwed in the valve body 1 to compress the spring 6, thereby keeping the spring 6 and the pressure compensating valve 5 from coming in operation. Where the injection speed is low, for example, more than 2 seconds, the bolt 10 is loosened so that the valve 5 is ready for opertion. Thus a dispersion on the dimension of moldings discharged by the injection molding machine is prevented from arising at each shot.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a crack in a valve stem through quenching or blowing of dust. SOLUTION: A valve element 3 is provided with first and second valve stems 3a and 3b. Ceramic rings 3c and 3d for heat insulation and temperature insulation, having diameter larger than that of the valve stem are mounted in a connecting state. The ceramic rings 3c and 3d consists of an annular protrusion protruding between the valve element 3 and the two valve stems 3a and 3b in a manner to front on a flow passage 2. The valve stems 3a and 3b and the ceramic rings 3c and 3d are molded by mixing together a silicon nitride sintered substance formed by mixing approximate 80 wt.% a silicon nitride (Si3N4) and approximate 20 wt.% a rare earth oxide (Y2O3, Yb2, Yb2O3) and baking the mixture at a high temperature of 1400-2100 deg.C. Thus, since the silicon nitride sintered substance has material characteristics of a bending strength of 760-800 Mpa (at 1000-1400 deg.C time) and heat resisting impact properties of 1200 deg.C, an inflow of a high temperature high heat in the direction of the valve element is effectively quenched and an O-ring, a V-ring, and gland part are insulated from temperature and heat.

Abstract: PURPOSE:To evade the zero shift of a measuring value and to improve accuracy by performing a simple operation to control the heat current of a heater wound across a bypass passage, and to eliminate convection between a measuring flow tube at flow rate of zero. CONSTITUTION:Fluid in the bypass passage 3 is heated with a convection preventing heater 7, however, a heat condition can be decided depending on the heat temperature of a heater 4 which heats the fluid in the measuring flow tube 2. Such operation is performed to eliminated the change of specific gravity essentially due to the temperature of the same fluid passing the inside of the measuring flow tube 2 and the bypass passage 3 and to prevent a circulation flow by the change of the specific gravity occurring. The convection can be eliminated by controlling a variable resistor VR and setting the output of a bridge circuit setting an upstream sensor 5 and a downstream sensor 6 as temperature detecting resistors at the flow rate of zero at zero in the same fluid to be measured.
