Title: Wafer alignment device
Inventor: YOKOYAMA TAKASHI
IPC: H01L21/68
Filed: 1986-09-11
Abstract: PURPOSE:To solve a problem on limitation for the position of alignment marks, by installing auxiliary radiation parts for resist pre-bleaching so that either one of them is selected face field exposure irradiation parts in order to obtain changing irradiation.

Title: Method and apparatus for measuring water content by microwave and tea making process control method used therein
Inventor: MASUDA SUSUMU
IPC: G01N22/04
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To obtain a microwave permeation type moisture meter for measuring low moisture capable of measuring the moisture of tea leaves or the like of low water content with high accuracy. SOLUTION: The transmission path between a microwave transmitter and a microwave receiver is formed from a microstrip line 10 and picked leaves before, after or during processing by a tea making machinery are positioned so as to be allowed to face to the microstrip line 10, and the water content of tea leaves is calculated from the difference in receiving level generated by the absorption of a microwave by the moisture contained in tea leaves. Since tea leaves close to the microstrip line 10 become a measuring object, if tea leaves A of a constant bulk or more are positioned on the microstrip line 10, a measuring error is not generated even when a sampling amt. is different. Since the measurement of the wt. of tea leaves becomes unnecessary and the measuring error of a wt. is not included, water content can be measured highly accurately.

Title: Manufacture of injection-molded hollow product and the product
Inventor: TSUJIMURA SUSUMU
IPC: B29C49/04
Filed: 1993-08-27
Abstract: PURPOSE:To require no component for closing a hollow portion and improve the external appearance of an injection-molded hollow product by providing a thick-walled portion having the hollow portion in a resin semi-finished product at the time of injection molding, providing a cylindrical portion for injecting gas into the hollow portion on the semi-finished product, pressing a recessed portion provided at the top end of a heating head against the cylindrical portion and closing the cylindrical portion by melting it under heating. CONSTITUTION:A hollow portion 35 is provided in a thick-walled portion 34 formed to a semi-finished product A, and a cylindrical portion 38 for gas injection is formed in a surface position of the thick-walled portion. Further, a heating head 43 has a recessed portion 45 at the top end thereof and the recessed portion is formed, for example, into a substantially semispherical recess. When the recessed portion 45 is pressed against the gas injection cylindrical portion 38, the top end of the gas injection cylindrical portion 38 is melted and deformed so as to be directed toward the center thereof along the inner face of the recessed portion 45, whereby an opening 38a at the top end of the gas injection cylindrical portion 38 is closed to form a closing 37. Since the heating head 43 allows the periphery of its recessed portion 45 to intrude into a recess 36, the position of the closing 37 becomes substantially the same level as a surface 21 of the semi-finished product A or lower than that.

Title: Double chain type drawing bench
Inventor: AOYANAGI KAZUYA
IPC: B21C1/22
Filed: 1983-11-11
Abstract: PURPOSE:To suppress breakage of pawl part at the tip of a hook, to eliminate coming off of the hook and to perform efficient drawing by providing a chain equalizer mechanism that eliminates deviation between chains and the hook of a truck that couples with the chains. CONSTITUTION:In the case where elongation of two chains 27, 27 is different at the time of drawing, an equalizer box 16 and shafts 20, 20 rotate horizontally around a pin 15a according to the difference of elongation and act to make tractive force given from the two chains 27, 27 nearly equal. In this case, deviation in the direction of width occurs between the center line of hooks 19, 19 and center line of chains 27, 27. The hooks 19, 19 are supported pivotally to allow free rotation around connecting pins 21, 21, and shafts 22, 22 and hooks 19, 19 are connected loosely. Accordingly, the deviation in the direction is eliminated by reaction force moment that acts from ring plates of chains 27, 27 to hooks 19, 19. Consequently, generation of excessive bending and torsional stress between the pawl part of hooks 19, 19 and ring plates is prevented.

Filed: 1984-10-11
Abstract: PURPOSE:To perform switching in short time thus to improve the production ability by providing plural systems of dirt liquid tank, clean liquid tank and machines in working liquid feeding system thereby facilitating selective feeding of working liquid having necessary specific resistance. CONSTITUTION:Working liquid feeding system is provided with A and B systems where each feeding system can set the specific resistance independently and the working liquid to be fed to the machining section can be selected through changeover of switch to function main feed pump 8a or 8b. Upon function of main feed pump 8a in A system, the delivery liquid will try to flow into B system as well as to the machining section but it is prevented by a check valve 14b. Consequently, the discharged liquid from the machining tank is led to the dirt tank 2a or 2b in A or B system through changeover of discharge liquid changeover valve 13. In such a manner, the changeover time of the specific resistance of working liquid with correspondence to machining conditions can be shortened resulting in improvement of productionability.
