Title: Method for injecting sample by automatic sampler for liquid chromatograph
Inventor: SAITO KATSUHIKO
IPC: G01N30/24
Filed: 1987-11-17
Abstract: PURPOSE:To obtain data having good reproducibility by executing control in such a manner that an automatic sampler packs the next sample into a sample loop during analysis of the previous sample and introduces the sample into the flow passage of a column at the specified timing after the end of the previous analysis. CONSTITUTION:Two kinds of moving phases A, B, are fed by pumps 1a, 1b and the sample is automatically injected into the automatic sampler 3 by control of a controller 2 and is fed via the column 4 to a detector 5. The time from the start of the analysis to the execution of the next sample injection operation is then set in the controller 2 and the first sample is introduced into the column. A timer is simultaneously reset. The next sample is sucked at the set time and the previous sample is packed into the sample loop. The next sample is introduced into the column as the analysis time passes by. The specified column state is thus maintained even in the case of the analysis to change the compsn. of the moving phases. The analysis is thus carried without the good reproducibility.

Title: Lenticular screen
Inventor: HIROSE KIICHIRO
IPC: G03B21/625
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To reduce notches of the edge part of a black stripe by reducing the thickness of a support and enlarging the width of the black stripe thus easily controlling high black stripe rate. SOLUTION: A lens surface forming layer 12 is formed on either surface of a lens support 11. A photosensitive material layer 13 is formed on the surface of the supporting body 11 opposite to the lens forming surface thereof. By utilizing lens condensing characteristics, the black stripe 16 is formed at a part other than a condensing part. A diffusion forming layer 14 is laminated on the layer 13. The width of the black stripe 16 is adjusted by changing the thickness of the support 11, not by exposure. If the thickness of the support is made smaller than a lens condensing distance, a condensing position comes near to the middle of the layer 13 and the transmission width of a light beam becomes small. By setting base material in such a way, the black stripe forming width is made large.

Filed: 1999-10-14
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming wiring wherein the erosion of a low-k (low dielectric constant) film in a process for forming an embedded wiring can be prevented. SOLUTION: When a polysilicon is used as the material of a lower-layer wiring 102, a side-wall deposit 118a comprising Si is formed on the side wall of a via hole 110 by sputtering on the surface of a lower-layer wiring 102 in a via hole formation process S5.
