Title: Silicon carbide core tube for semiconductor diffusion furnace
Inventor: TANAKA TAKASHI
IPC: H01L21/22
Filed: 1987-08-14
Abstract: PURPOSE:To improve sealing properties by mounting a flange at the end section of a core tube body, fitting a cap made of quartz glass to the flange and joining the flange using a clamp. CONSTITUTION:A flange 2 is formed at the end section of a core tube body 1 composed of silicon carbide, a cap 5 having an exhaust port 5a and being made of quartz glass is engaged with the flange 2, and the flange is joined by a clamp consisting of plate materials 3 manufactured by dividing a ring into two and bolts and nuts 4. Since a taper is not shaped to the silicon carbide core tube body 1, heat is hardly conducted to the cap 5, and the temperature of the cap 5 is not elevated as seen in conventional devices. Accordingly, the core tube body can be sealed positively without damaging the cap made of quartz glass, and an O ring, etc., can be used and sealing properties can be improved.

Title: Identification structure of object and object with the structure
Inventor: HOSHINO SHUICHI
IPC: B42D15/10
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To provide the identification structure of an object which is generally circulated but is extremely difficult to forge and identifiable with high accuracy. SOLUTION: A polymer cholesteric liquid crystal with one type or two types of reflective wavelength is used as a security medium to be provided on an object. Consequently, it is possible to easily identify the genuineness of the object on account of the positively identifiable characteristics, stability and extreme difficulty to manufacture, and besides with high reliability. Thus the effects to prevent forgery from being committed can be enhanced. Further, as the polymer cholesteric liquid crystal is low-priced, there is no possibility that the manufacturing cost of the identification structure of the object may be increased.

Abstract: PURPOSE:To uniformize the temp. distribution of a crucible and to form a stabilized high-quality thin film by making the crosssectional area of a hot cathode for electron bombardment vertical to the current flowing direction smaller than that of the part opposed to the upper and lower parts of the crucible. CONSTITUTION:The cross-sectional area of the hot cathode 11 vertical to the current flowing direction is made smaller at the part corresponding to the upper and lower parts of the crucible 8 than at the part corresponding to the center. Consequently, the electric resistance of the cathode 11 per its unit length is made larger at the upper and lower parts of the crucible 8 than at the center. Accordingly, the temp. of the cathode 11 is made higher at the part corresponding to the upper and lower parts of the crucible 8 than at the part corresponding to the center, the emission current value is remarkably increased at the part corresponding to the upper and lower parts of the crucible as compared with that at the part corresponding to the center, and the heat input to the crucible 8 is increased at the upper and lower parts of the crucible 8 as compared with that at the center. As a result, a decrease in the temp. at the upper and lower parts of the crucible is compensated, and the temp. distribution of the crucible is uniformized.

Title: Power system simulator
Inventor: NOGUCHI HIDEO
IPC: G06F19/00
Filed: 1993-08-18
Abstract: PURPOSE:To suppress the generation of high frequency by correcting the current frequency based on a frequency correction interval independent from the variation of phase angle, the current frequency, and the calculation time interval thereby making smooth the waveform even upon abrupt variation of the frequency or phase angle. CONSTITUTION:A simulating section simulates the phenomenon of a power system at a calculation time interval DELTAT and outputs the effective value of voltage or current, the frequency, and the phase angle in the form of digital data. A frequency correcting section 80 receives, at first, a phase angle theta and a frequency (f) from the simulating section at the calculation time interval DELTAT and DELTAt0 from the input section and a DELTAtheta operating section 81 determines the difference DELTAtheta between the original phase angle theta1 and an updated phase angle theta2. A DELTAt operating section 82 then receives a frequency correction operating interval DELTAt as an input value DELTAt0. An fn operating section 83 operates a correction frequency fn according to a formula f2+DELTAtheta/2piDELTAt and outputs the correction frequency fn thus determined. This constitution allows synchronous throw-in with an analog unit at all times.
