IPC: C08K5/09
Filed: 1989-02-02
Abstract: PURPOSE:To obtain the title composition having accelerated crystallizability and being moldable at low temperatures by mixing a styrene polymer chiefly having a syndiotactic structure with a nucleator such as an organophosphorus compound and a crystallization accelerator such as a polyoxyalkylene compound.

Title: Pressure regulating valve and manufacture thereof
Inventor: NAKANO AKIO
IPC: F02M69/00
Filed: 1994-02-21
Abstract: PURPOSE:To realize the liquid-tightness between the inside of a first chamber and the outside through an effluence pipe, by an inexpensive simple manufacturing method as for a pressure regulating valve which maintains the liquid pressure in the first chamber at a prescribed valve by the action of a diaphragm. CONSTITUTION:An effluence pipe 25 is shaped by bending-shaping the upper end part of a cylindrical member which is formed by rounding a plate-shaped member and welding the opposed sides, so that the upper end surface 25b is directed to the inside of the cylindrical member. A valve seat member 26 is press-fitting-fixed with the effluence pipe 25. The pressure in the first chamber RI is adjusted by the valve action between the valve seat member 26 and a valve body 32 fixed at the center part of a diaphragm 23. Accordingly, even if a welding bead is generated at the welded part of the effluence pipe 25, the liquid-tightness between the effluence pipe 25 and the valve seat member 26 is maintained, since the upper end surface 25b of the effluence pipe 25 is press-attached with the side surface of the valve seat member 26.

Title: Method of aligning mask and wafer
Inventor: TOJO TORU
IPC: G01B11/00
Filed: 1988-02-03
Abstract: PURPOSE:To enable the execution of alignment with excellent SN even in a state wherein images of a mask mark and a wafer mark deviates from each other, by forming these marks so that the dimensions of one of them are larger than those of a projected image of the other. CONSTITUTION:A mask mark is formed to be about several times larger than the product of the dimensions of a wafer mark 21 and the inverse number of the transferring magnifying power of a projection lens 3. Herein pattern pitches of the mask mark 22 and an image 21' of the water mark are equal to each other. In this constitution, the image 21 ' of the wafer mark can be formed within the mask mark 22 even when any deviation is caused by the presence of turn-back mirrors 13a and 13b, and exact position alignment of a mask 2 and a wafer 4 can be realized by an alignment signal being free from the lowering of SN. In addition, a mechanism for driving the turn-back mirrors 13a and 13b finely is dispensed with and thus the design and structure of the turn-back mirrors are simplified.

Filed: 1991-01-25
Abstract: PURPOSE:To facilitate a remarkable change in a most-significant digit by using a rotary encoder so as to set outputs such as a voltage and a current. CONSTITUTION:A frequency voltage converter 3 converts a frequency of an output signal of a rotary encoder 2 into a voltage. A comparison section 4 compares an output voltage of the frequency voltage converter 3 with a reference value corresponding to a frequency range.
