Title: Thermal processing apparatus
Inventor: KONO MICHIHISA
IPC: H01L21/265
Filed: 1991-07-11
Abstract: PURPOSE:To improve reproducibility and uniformity of electrical characteristics of an ion-implanted semiconductor by forming a trapping type holder with a cover for loading a sample with a material such as silicon, which does not allow vaporization of elements at a thermal processing temperature and ensures excellent infrared absorption coefficient, in a thermal processing apparatus of a semiconductor substrate. CONSTITUTION:Halogen lamps 1 are disposed at the upper and lower outside of a quartz glass furnace tube 2. A 3-inch GaAs substrate 3 is housed within a Si holder 4. The holder 4 is formed as a disk measuring external diameter of 125mm and thickness of 1.5mm. The holder 4 houses a substrate 3, provided with a cover 6 made of Si and is then loaded within a furnace tube 2 with support of a quartz glass pin 5. With this structure, the holder is heated by the infrared emitted by the halogen lamp 1. Namely, Si is implanted in the quantity of 1X10<13>cm<-2> to an undoped semi-insulating GaAs substrate with an implantation energy of 10keV by the surface orientation <100> LEC method at a room temperature. As a result, fuluctuation of sheet resistance can be improved in comparison with that of a graphite holder.

IPC: G11B23/03
Filed: 1990-07-23
Abstract: PURPOSE:To prevent the wear and the damage of a disk at the time of contact to the disk by providing a disk receiving member, which is provided with ruggedness on the surface facing the disk, on one side face of a case main body facing the disk. CONSTITUTION:Notched parts 4a are formed at prescribed intervals to provide a ruggedness on the side peripheral surface facing the side face of an optical disk 1, and the disk receiving member 4 is fixed concentrically to the periphery of the end part on the center part side of an access window 2e to the window 2e by adhesion. Since the side peripheral surface of the disk receiving member 4 facing the optical disk 1 is made rugged, the rugged part of the optical disk receiving member 4 is displaced in the rotating direction of the optical disk 1 by friction between the optical disk 1 and the optical disk receiving member 4 and the frictional force between them is reduced to relax the impact up the optical disk 1 when the optical disk 1 is brought into contact with the side peripheral surface of the disk receiving member 4 while rotating. Thus, the wear of the optical disk and the disk receiving member 4 is reduced.

Title: Current switching type logic circuit
Inventor: YAMADA KAZUMI
IPC: H03K19/086
Filed: 1987-08-06
Abstract: PURPOSE:To cope quickly with a request of temperature characteristic change by using a control signal to drive a switching circuit, and connecting/ disconnecting the cathode of a 1st diode to/from the anode of a 2nd diode thereby making the same circuit into plural current switching type logic circuits each different in output voltage temperature characteristic. CONSTITUTION:An N-channel MOS transistor(TR) Q1 and a P-channel MOS TR Q2 are connected in parallel between the anode of a diode D2 and a connecting point between the cathode of a diode D1 and a resistor Rx. Thus, with a control signal supplied to the gate of the N-channel MOS TR Q1 is at a high level, and the inverse of control signal, inputted to the gate of a P-channel MOS TR Q2 is at a low level, since the TRs Q1, Q2 are turned on, the cathode of the diode D1 and the anode of the diode D2 are connected. That is, the cathode of the 1st diode D1 and the anode of the 2nd diode D2 are connected/disconnected. Thus, the same circuit is used for plural current switching time logic circuits whose temperature characteristics differ from each other.

Title: Method for controlling position of weld mark
Inventor: MOROHASHI TSUNEO
IPC: B29C45/26
Filed: 1993-08-10
Abstract: PURPOSE:To provide a method for controlling a position of weld marks for making better products by controlling generating position of the weld marks in a plastic product molded by injection. CONSTITUTION:A resin reservoir 5 is provided at a passage side of a flow B of melting resin which takes a roundabout way to a lower side of a parts mounting hole 2 by evading it. An inlet 6 of the resin reservoir is arranged obliquely immediately before the parts mounting hole 2 so as to flow in easily. Accordingly, the melting resin injected into the inside from an inlet (gate) 4 of a mold flows in straightly to the left side where there is no resistance. At the opposite side, flows A and B of the melting resin flowing to the back by taking roundabout ways to both sides of the parts mounting hole 2 by avoiding it are produced. However, as a part of the flow B is changed to a flow C by the resin reservoir 5 so as to flow into the resin reservoir 5, the flow B slows down by the part of the flow C so that the flow B thereafter is delayed. Instead, the flow A compensates the deficiency of the flow B. Accordingly, a confluence is produced near the gate 4 in the passage of the flow B where a weld mark 3 generates.

Title: Plate structure
Inventor: ISHIKAWA HIROSHI
IPC: F16D35/00
Filed: 1989-07-31
Abstract: PURPOSE:To prevent thermal deformation and rotary displacement of a spacer for a viscous coupling plate by making at least a portion near the edge of the spacer nearly ring-shaped engage with the plate. CONSTITUTION:Splines 19 and slits 21 are formed in an outer plate 9. Engagement holes 23 are provided on a radially inner side of the spline 19. A spacer 25 is a ring of which one portion is cut off and the cut ends are bent in the axial direction. The spacer is attached to the plate 9 by making the bent end 27 engage with the engagement hole 23 to keep an interval of the plate 9 constant. Thus, since the ends of the spacer do not come in contact with the plate with which the spacer engages, wear and damage are prevented. Assembling cost is considerably reduced.

Filed: 1981-12-10
Abstract: PURPOSE:To produce foamed particles of natural glass of low bulk density which are foamed uniformly at high degrees by preheating powder and granules of natural glass beforehand at suitable temps., then heating the same up to a foaming temp. CONSTITUTION:After powder and granules of natural glass such as perlite, obsidian, pitchstone and the like are preheated for 2-60min at 600-900 deg.C, said powder and granules are heated to the foaming temp. higher than about 900 deg.C, whereby foamed particles having high performance as noncombustible lightweight heat insulating materials which are formed uniformly at high degrees are obtained. By the above-mentioned method, foaming extents can be considerably increased or with the foamed particles by which foaming extents equal to those in the prior art are obtained, the foaming temp. or time by heating can be reduced. If the preheating temp. is below 600 deg.C, the effect is low, and if >=900 deg.C, the glass powder and granules start foaming and there is no preheating effect. If the preheating time is shorter than 2min, the effect is low, and if longer than 60min, it is undesirable that the foamability tends to decrease.
