Title: Laser beam welding method of metal thick plate
Inventor: SUEDA AKIRA
IPC: B23K26/00
Filed: 1993-10-29
Abstract: PURPOSE:To enable the piercing welding not having melt down by setting a heat input quantity to the prescribed condition at executing flat/butt welding of thick plate by laser beam. CONSTITUTION:When a metal thick plate is subjected to flat/butt welding with using laser beam, a heat input quantity Q by laser beam is set so as to satisfy the condition in the inequality and welding is executed. In the inequality, Q: heat input quantity (KJ/cm), h: plate thickness (mm), V: welding speed (cm/min) sigma: surface tension of molten metal (dyn/cm<2>), rho: density of metal (g/cm<3>), t: constant obtained relationship between laser output and piercing thickness, g: acceleration of gravity (cm/sec<2>). When heat input quantity Q can not satisfy the condition of the inequality, piercing welding becomes impossible due to insufficient melt down. When heat input quantity Q exceeds the condition of the inequality, because a molten metal quantity becomes excessive, melt down of molten metal is generated, sound bead is not formed.

Title: Manufacture of travelling-wave tube
Inventor: TAKEDA MITSUO
IPC: H01J23/00
Filed: 1985-12-05
Abstract: PURPOSE:To make it possible to secure a high vacuum operation for a long period of time, by discharging the gas housed in bulk getters themselves, and absorbing the gas from the getters and the gas discharged from electrodes in the tube during the adjusting and the ageing processes of the focus magnetic field device by an auxiliary pump. CONSTITUTION:An ion pump 35 is operated in the adjusting and the ageing processes of a focus magnetic field device 13. The gas is discharged from the getters themselves by heating the bulk getters 31 and 33. In such a way, the housed gas is discharged from the electrodes in the tube such as a helix electrode and collector electrode. Such a discharged gas is scarcely absorbed by the getters but absorbed by the ion pump 35, because the getters are kept at a high temperature. By sealing up the way of a connecting pipe 34 at the point of the mark X, and cutting off the ion pump 35 from the tube body, a travelling- wave tube is completed.

Title: Exclusive controller
Inventor: SUMIMOTO SHINJI
IPC: G06F9/46
Filed: 1991-10-21
Abstract: PURPOSE:To prevent the deal lock at the time of exclusive control and to effectively implement exclusive control for resources under the distributed environment. CONSTITUTION:In a key access table, key matrix consisting of keys K1 to K9 corresponding to resources R1 to R9 is defined, and each element of key matrix K1 to K9 is set to '1' when the resource is not exclusively controlled (when it is free) and set to '0' when the resource is occupied. When an exclusive control request of resources R1, R5, and R9 comes from a CPU, a pattern generation part generates the corresponding key pattern. A key matrix pattern representing a state of use of all resources is stored in a resource access table. The exclusive control request from the CPU is enabled when the patterns are collated and the key patterns coincide with each other and all the required resource keys are free. In this case, the key patterns are noncoincident, the acquired key is released and the exclusive request from the CPU is inhibited.

Title: Head rest and its production
Inventor: TAKEUCHI NOBUO
IPC: B60R21/055
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To take measures for void sufficiently even in a multilayer skin material by forming a skin from the multilayer skin material using a fabric skin material and a seam line on a skin piece constituting a head rest bottom surface. SOLUTION: A foaming raw material is injected from an opening 14 between a skin 1 and a core part to do foaming. In the course of foaming, air in the skin 1 and most of excess foaming gas is discharged from the opening 14 outside the skin 1. In an uppermost skin part, air and excess foaming gas are discharged from a seam line 4. In the seam line, since a sewing thread 41 passes through a needle holes opened by a sewing machine needle and others, the intervals between the needle holes are made extremely small. Although air and foaming gas can be discharged from the holes, the liquid foaming raw material can hardly be discharged. Troubles such as the pollution of the skin 1 by the leakage of the raw material through the needle holes outside the skin can be prevented during foaming while void measures being taken.
