Title: Method and device for exposure
Inventor: SOMEYA ATSUSHI
IPC: H01L21/027
Filed: 1994-03-31
Abstract: PURPOSE:To improve the working efficiency of pattern exposure on a wafer. CONSTITUTION:A prealigned wafer is placed (S11 and S12) on an exposure stage. Then, in the first process (S13), a light is scanningly made to irradiate on the surface of a wafer, and the change of intensity of the light reflected by each alignment pattern of the wafer is measured. The change of intensity of light is detected as the waveform of each alignment mark. In the second process (S14), the prescribed number of alignment marks, to be used for alignment of the wafer, is selected based on the waveform of the detected alignment mark. In the third process (S15), the wafer is aligned using the selected alignment mark. In the fourth process (S16), a pattern exposing operation is conducted on the wafer by projecting the exposing light on the aligned wafer. In this exposing method, the alignment pattern, to be used for alignment, is selected by an arithmetic processing.

IPC: F15B20/00
Filed: 1979-07-10
Abstract: PURPOSE: To avoid accidents from an erroneous attachment of a regulator valve in a cylinder for fork-lift truck where the regulator valve is commonly used for both heavy loads and light loads, by forming stepped portions on the regulator valve to prevent it from being installed in an opposite direction.  
     CONSTITUTION: The circumference of a regulator valve 4 for heavy load cylinder C2 is formed into steps. A spacer 10 having a diameter greater than the larger stepped portion 42 is mounted on the smaller stepped portion 40. On the other hand, a hole 32 having a small diameter and adapted to fit with the larger stepped portion 42 and another hold 34 having a large diameter and adapted to fit with the diameter of the spacer 10 are formed in the cylinder bottom housing 3. An attachment hole 30 is also formed at the side including the another hole 3 for the installation of a regulator valve 4. Owing to the above construction, even if one tries to attache the regulator valve 4 in an opposite way, he can never secure it at a correct attachment position by the small hole 32 of the cylinder bottom housing 3. This ensures the attachment of the regulator into the heavy load cylinder C2.

IPC: G11B5/127
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to produce a high-accuracy glass rod which is not crystallized and to produce the glass rod which satisfies the requirements for the 'lower reaction with core material at a fusing temp.' and the 'lower reaction with a metal material at a fusing temp.'. SOLUTION: This apparatus for producing the glass rod produces the glass rod by heating a vessel 2 in which a glass raw material 1 is put to fuse the raw material and pulling down the fused liquid glass via a drawing-out nozzle 5 connected to the bottom 2a of the vessel 2. The bottom 2a of the vessel 2 is formed flat. The cooling rate of the fused liquid glass is, therefore, made higher than in the case the bottom of the conventional vessel is formed to a conical shape. The glass rod which is not crystallized is thus stably manufactured.

Thereafter it is passed through an outlet chamber 10 and a return path 11 and recirculated through the same circuit. After disintegrating treatment has been completed, this disintegrated fine powder is taken out from a takeout port 12 of a product. Fine powder receives impact in the impact part 8 between the blade 4 and the liner 7 and disintegrated. The gap a between the blade 4 and the liner 7 is the shortest gap and regulated to 0.5-10mm. The space correspondent to the width b of the blade 4 is the impact part. The fine powder to be treated is surely passed through the narrow gap between the rotary piece and the fixed piece. In this case, the fine powder receives impact by the rotary piece and recycling function is imparted thereto in accordance with necessity and thereby surer disintegration is enabled.
