Title: Heat-treating device
Inventor: SHIMAZU TOMOHISA
IPC: H01L21/205
Filed: 1995-03-13
Abstract: PURPOSE: To provide a heat-treating device which can be improved in throughput by quickly raising and lowering the temperatures of substrates to be treated by sufficiently reducing the inplane temperature differences between the central parts and peripheral parts of the substrates not only under a normal pressure but also under a reduced pressure. CONSTITUTION: In a heat-treating device which heat-treats substrates W housed in its heat-treating chamber, a shield members 19 which shield the peripheral parts of the substrates W from heat radiation incident on the peripheral parts at angles larger than a prescribed angle θ are provided around the substrates W. Although the peripheral parts of the substrates W are apt to be affected more as the incident angles of the heat radiation increase (become normal to the planes of incidence), the influence of the heat radiation on the peripheral parts is suppressed, because the members 19 shield the peripheral parts from the heat radiation incident on the peripheral parts at angles larger than the angle θ.  Therefore, the throughput of the heat-treating device can be improved, because the temperatures of the substrates W can be raised and lowered quickly by sufficiently reducing the in-plane temperature differences between the central and peripheral parts of the substrates W not only under a normal pressure but also under a reduced pressure.

Title: Spark plug for internal combustion engine and its manufacture
Inventor: MATSUTANI WATARU
IPC: H01T13/39
Filed: 1994-04-19
Abstract: PURPOSE:To provide a spark plug, which hardly causes misfiring even in the case that the air-fuel ratio is large, and can get enough combustion property and is excellent in durability, and its manufacturing method. CONSTITUTION:A noble metal is fit in the groove made around the tip of a center electrode parent material or its vicinity, and those are fused and jointed together by applying a YAG laser beam so as to make noble alloy, and the tip of the center electrode parent material is excised by cutting, cutting off, or polishing, thus the noble metal alloy part is arranged at the rim 11 of the tip face 13 of the center electrode 10. Moreover, the position of the tip face 13 of the center electrode is placed at the same position as that of the tip 22 of an outside electrode 20 or at the position pulled down by 0.0-0.5mm from it. Since the exposed rim 11 of noble metal alloy forms an ignition part in the condition that it is retreated a little from outside electrode 10, this is excellent in durability and also hardly causes ignition errors even in the case that the air-fuel ratio is large.

Title: Injection device of motor-driven injection molding machine
Inventor: EMOTO ATSUSHI
IPC: B29C45/50
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To ensure easy maintenance and control services and at the same time, improve the accuracy of controlling speed, position and back pressure by arranging a motor for weighing on the same axial line as for a screw, and providing a means to restrict a relative motion in the rotating direction and allow a motion in the axial direction. SOLUTION: A motor for weighing 44 is arranged on the same axial line as for a screw. When current is supplied to the stator 46 of the motor for weight 44, a rotor 47 is rotated and the rotation is transmitted to a first spline shaft 63 through a first rotor shaft 56 and a first spline nut 62 for rotation. This rotation is transmitted to a screw which is, in turn, rotated. Following this rotation, a resin 33 moves forward being melted through a groove 26 and the screw is moved backward by a back pressure generated due to the movement of the molten resin. In this case, the first spline shaft 63 connected through a spline linkage moves backward relatively with the first spline nut 62. Thus a timing belt is not required for the action of the screw, so that the maintenance and control of the injection device are easy and the controlling accuracy is improved.

Title: Production of alloy plated steel wire
Inventor: OBA HIROSHI
IPC: C23C2/38
Filed: 1989-03-31
Abstract: PURPOSE:To improve fatigue strength and bendability by specifying cooling velocity in a specific temp. region at the time of continuously cooling a steel wire after hot-dipped with Zn-base alloy. CONSTITUTION:After a wire rod is wiredrawn to the prescribed wire diameter, the resulting wire is subjected, with or without the application of galvanizing, to hot dipping by using a bath consisting of 2-12% Al and the balance Zn and the steel wire after the above plating is continuously cooled. In the above method, at the time of continuously cooling the plated steel wire, average cooling rate in the temp. range between 300 and 150 deg.C is regulated to 4 deg.C/ sec-15 deg.C/sec. By this method, an alloy plated steel wire having high fatigue strength and superior bendability can be obtained. When the above cooling rate exceeds 15 deg.C/sec, fine cracks are developed in the plating layer and fatigue strength is reduced because the progress of eutectoid reaction is delayed in the cooling stage, and, on the other hand, surface flaws due to contact with guides after plating are increased when the cooling rate is lower than 4 deg.C/sec.
