Abstract: PURPOSE: To enhance the heat treatment quality for the semiconductor wafer by using the auxiliary tube featuring an outer dameter smaller than the inner diameter of the furnace core tube in the heat treatment by the open tube method.  
     CONSTITUTION: Auxiliary tube 7 which is composed of the heat-resistant material and then inserted into furnace core tube 1 contains branch tube 72 and 73 which are switched via switching valve 7 and then linked to gas path tube 71 piercing through cover 3 of tube 1. Semiconductor wafers 5 held by boat 4 are distributed to tube 7, and the inactive gas is jetted in from tube 72 in the case of the diffusion process for the impurity when wafer 5 is put in and taken out of tube 1. And in the case of the heat treatment, tube 7 advances up to the virtual line position, cover 3 is mounted to exit 12 of tube 1, and the gas to create the treatment atmosphere is introduced through gas inlet 11 and then exhausted through tube 73. Thus, the oxidation due to the external atmosphere can be avoided when the wafer is put in and taken out, the slow cooling effect being expected. Furthermore, the external atmosphere is prevented from intruding through the gap between tube 7 and cover 3 under processing, thus realizing the uniformity and the quality of the heat treatment.

Title: Abnormality detecting circuit and data terminal device
Inventor: KUSHITANI KAZUHIRO
IPC: H04L69/40
Filed: 1995-06-27
Abstract: PURPOSE: To speedily and precisely detect the abnormality of an ST2 signal before data begin to be transmitted. CONSTITUTION: When an ST2 signal is normally inputted to the full-wave rectifying circuit 151 of an abnormality detecting circuit, the ST2 signal is rectified on a full-wave basis and a current flows from the side of a capacitor C to a light emitting diode D5 through a resistance R1, so that this diode D5 illuminates. Consequently, a phototransistor T turns on and a detection signal as its collector voltage goes down to a low level, indicating that the ST2 signal is normal.  If the ST2 signal is continuously at the low level owing to an open circuit, the voltage on the side of the capacitor C becomes zero and the current supply to the light emitting diode D5 is ceased to disable the light emitting diode D5 to illuminate, so the phototransistor T turns off and the detection signal as its collector voltage goes up to a high level, thereby informing the CPU of an data terminal device, unshown in the figure, of the abnormality of the ST2 signal before data transmitting operation.

After that, bit switching from the transmission signal sequence of the system in use to that of the spare system is performed at every bit unit. Thereby, the switching of the system from the one in use to the spare one without generating the hit can be completed.

Abstract: PURPOSE:To obtain the result of the test automatically and accurately without confirming the change in color of test paper during the test when the thermostability test of vinyl chloride resin is conducted. CONSTITUTION:A specified amount of a sample 5 of vinyl chloride resin is inputted into a test tube 4.

The sample 5 is heated and thermally decomposed by submerging the test tube 4 into the oil well 2, and hydrochloric acid gas is generated. The generated hydrochloric gas reacts with water in the glycerin contained in the pulp, and the electric resistance between two electrodes 8 and 9 is remarkably decreased. Then, a voltage which is applied across two electrodes 8 and 9 is also decreased. The voltage drop is recorded in a recorder 14. The time of the voltage drop across two electrodes 8 and 9 is measured as the time when the thermal decomposition of the sample 5 is started.

Abstract: PURPOSE:To facilitate production by integrating and fixing many rod-shaped glass bodies, each one of which has internally an optical density distribution and which are in the arrayed state, by filling the spacings therebetween with a light shieldable material. CONSTITUTION:This optical mask is constituted of the many rod-shaped glass bodies 1 each of which has internally the optical density distribution and is made to a circular columnar shape and the light shielding part 2 consisting of the light shielding material enclosing the spacings between the glass bodies.

Abstract: PURPOSE: To obtain a large scale IC by a method wherein the strain of a field oxide film, which affects an active region, is made small only by the division of a field region without making the field oxide film thinner.  
     CONSTITUTION: An oxide thin film region 6, which has no field oxide film, is formed on the circumference of a gate circuit (active region) 1. In this constitution, the region 6 absorbs the strain created by a field oxide film 2, thus not arriving at an active region 1A. The strain of the active region 1A is influenced only by an oxide thick film 7 between the region 6 and the active region, which becomes remarkably small. The width of the region 6 can be extremely narrow. The main wiring is provided on a region 2 not on the region 6, or it may be orthogonally arranged with the region 6. By arranging such, the wiring area running on the region 6 becomes very small and the increase of the capacitance can almost be neglected.

Abstract: PROBLEM TO BE SOLVED: To reduce starting resistance by constituting an intersection point between a horizontal extension line of lip internal circumference bottom parts of inner/outer seal parts and a lip inclined line opposed to a surface to be sealed in such a state as being set towards the lip root side from the intersection point between the lip inclined line and the surface to be sealed or coinciding the both intersection points with each other. SOLUTION: When a piston is arranged, the shape and the dimension of an outer seal part 5 are so set that an intersection point P between the horizontal extension line Lb of a lip internal bottom part B and a lip inclined line Li opposed to a surface 3 to be sealed is positioned towards the lip root 1 3 side from the intersection point Q between the lip inclined line Li and the surface 3 to be sealed, or coincided therewith each other.  When an intersection point between a tangent Ls , which passes through the lip internal bottom part B to be in contact with the piston main body 4, and the extension line of the lip inclined line Li is set to A, the compressive force overpasses the apex P of a reaction generated triangle core part 14 so as not to be applied to a side towards the A point and therefore an elastic reaction is small and starting resistance and sliding resistance, which are received from the surface 3 to be sealed by the outer seal part 5, are small. The same thing can be said in the inner seal part.
