Title: Method of positioning diode of electron beam irradiation semiconductor amplifier with beam cutter
Inventor: MAKISHIMA HIDEO
IPC: H01L21/331
Filed: 1979-01-24
Abstract: PURPOSE: To readily position the diode of an electron beam irradiation semiconductor amplifier with a beam cutter by providing a laser light shield film at the periphery of the active region on the surface of the diode, irradiating light from the laser vertically from the hole of the beam cutter and relatively moving the diode and the beam cutter to obtain the maximum output point of the diode.  
     CONSTITUTION: An n - -type layer 23 and a p + -type layer 24 sequentially laminated on an n + -type substrate 22, an opening is perforated at an SiO 2  film 25, and an MO film 26 is formed thereon. Further, an Au layer 31 is formed around an active region to cover the oblique portion and flat portion of the film 25. Since the capacity is increased if this portion is excessively wide, this portion is set at suitable width, and irradiated with light to protect electrons and X-rays against the diode upon receiving of the electrons and X-rays through complicated routes. Voltage is applied through a resistor 33 to the diode 21 to monitor the voltage of the resistor 33 by a monitor 35. The laser light 32 is irradiated directly to the diode vertically, and the relative position between the diode and the beam cutter 36 is altered. When the voltage of the resistor 33 is at maximum, the beam passing through the hole of the beam cutter irradiates the active region of the diode entirely. Thus, the diode is  readily accurately positioned with respect to the beam cutter.

Abstract: PURPOSE:To improve a throttling characteristic of the flame in a burner for an indoor open- type combustion equipment such as a household-use heating equipment and a hot water heater by a method wherein it has a double flame hole structure having a specified clearance between the two. CONSTITUTION:A convex metallic net 9 is arranged at a mixing gas supplying part with a certain clearance being left against a burner body 8 having several flame holes 7. An area of flame holes 7 in the burner body 8 is made smaller than that of the flame holes opened in the metallic net 9, and the burner body 8 is made of a material such as zirconia and cordierite which can be ignited with catalyst. The fuel injected from the nozzle 6 is injected as mixing gas from the flame holes 7 of the burner body 8 in such a way as air is sucked through the primary air hole 4 under an injecting pressure of the fuel and passed through the metallic net 9. Upon ignition of the mixing gas, hot catalyst combustion is carried out at the burner body 8 where the flame holes 7 are contacted with the mixing gas. Then, as an amount of combustion at the nozzle 6 is gradually decreased, resulting in that a degree of red heating of the burner body 8 is reduced. In turn, it becomes possible to make a combustion in a wider flame hole area than the flame holes 7 of the metallic net 9, the combustion is transmitted to the metallic net 9 at the mixing gas, while a throttling of CO down to about 20%, with burning amount down to 20% are enabled, resulting in improving TDR.

Title: Manufacture of connecting rod
Inventor: MURAKAMI YOICHI
IPC: C21D9/00
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To provide a connecting rod excellent in both buckling strength and fatigue strength by hot-forging low carbon boron steel into a connecting rod shape, then quenching it, and applying coining and shot peening to forged material. SOLUTION: Raw material formed of low carbon boron steel is hot-forged into a connecting rod shape and then quenched, and coining and shot peening is applied to obtained forged material without tempering it. Since coining is applied in the quenched state with high dislocation density, the forged material 1 is positively hardened, and buckling strength as a connecting rod is improved. Since the raw material steel contains low carbon, over-hardening is not generated even in the quenched state, and the dispersion of quenching ability caused by low carbonization is dissolved at a low cost by adding boron. Residual tensile stress generated by coining is made disappear by shot peening, and residual compressive stress is generated so as to improve the fatigue strength of the connecting rod.
