Title: Beam splitter and optical information recording reproducing device
Inventor: KIYOMOTO HIRONOBU
IPC: G02B5/30
Filed: 1994-01-28
Abstract: PURPOSE:To decrease dependency of reflectance and phase difference of a beam splitter on incident angle by forming an optical multilayer film containing several kinds of materials on a substrate. CONSTITUTION:The beam splitter consists of substrates 51, 52 and dielectric multilayer film 53 as an optical multilayer film formed on these substrates. The dielectric multilayer film 53 contains at least three kinds of materials. For example, for 790nm designed wavelength, substrates 51, 52 has 1.76 refractive index, and three kinds of materials TiO2 (53a), Al2O3 (53b) and MgF2 (53c) are laminated to form a dielectric multilayer film 53 between these substrates fixed with an adhesive layer 54. By forming films 53a-53c of three kinds of materials, the splitter has two Brewster angles calculated for the substrates so that the reflectance for P-polarized light does not become 0 for any incident angle of light. Further, since the central value of the incident angle range is included between the two Brewster angles, stable reflection characteristics can be obtd. in the incident angle range.

Title: Fast backward searching method for wiring processing
Inventor: OOKI YOSHIE
IPC: H01L21/82
Filed: 1990-01-19
Abstract: PURPOSE:To increase the processing speed in the backward search of a maze method by making use effectively of the pipeline processing. CONSTITUTION:The value of '1' of a search flag is sequentially sent to the PEs taking charge of the contiguous grids on a retrieving path for each action of a means 8 in a backward search covering a target T of 8-h through source S of 3-h. When the value of '1' of the source flag reaches a source grid, an AND obtained between the search flag set to the source grid and a source flag is set at '1'. This fact is judged by a controller, etc. The action of the means 8 is repeated in a pipeline system until the judging result of the controller is equal to '1' and before the controller judges the OR of a means 9 is equal to '1' with all PEs. Thus the backward search processing speed is increased.

IPC: G03F1/68
Filed: 1979-01-31
Abstract: PURPOSE:To enhance etching accuracy by exposing a photoresist on a light-transmissive insulating film with a plurality of photomasks according to different ground mateials in simultaneous photoetching of the materials coated with the film. CONSTITUTION:Photoresist layer 9 is formed on PSG film 4 covering source electrode hole 5, drain electrode hole 6 and gate electrode hole 7 of a silicon gate MOS transistor, holes corresponding to holes 5, 6, 7 are made in layer 9, and film 4 is etched. At this time, first mask 10 is closely contacted to layer 9, and by applying ultraviolet rays 11 exposure for holes 5, 6 is carried out, followed by exposure for hole 7 with second mask 13. Since ground materials of film 4 are silicon epitaxial layers in source region 1 and drain region 2 and silicon in gate region 3, they are different in reflectance to ultraviolet rays. So, two kinds of photomasks are used to adjust exposure time according to the reflectance, thereby eliminating a photosensitive difference of photoresist 9. Thus, the etching accuracy of film 4 and the accuracy of hole 5, 6, 7 are enhanced.

IPC: A23B7/152
Filed: 1990-01-18
Abstract: PURPOSE:To certainly perform the spray feed of water by intermittently controlling the opening and closing of the valve provided to an air feed pipeline by a fluid control means spraying and feeding water from a nozzle and intermittently supplying air to the air feed pipeline from an air feed pump. CONSTITUTION:When the spray feed of water is performed, a switch 52 changing over the usual feed of water and the feed of water intermittently performing the feed of air during the feed of water is set to an ON-state to turn a switch 48 performing the feed of water ON. Whereupon, a control part 46 detects the signal thereof and opens a solenoid valve 27 and also automatically opens a solenoid valve 23 at the same time. Thereafter, the control part 46 opens and closes only the solenoid valve 23 intermittently at a definite interval. When the switch 48 is turned OFF after the feed of water is completed, the solenoid valves 23, 27 are together closed. By this method, the total pressure of an air feed pump 18 can be applied to a water feed pipeline intermittently during the feed of water and, therefore, no air feed pressure escapes from the air feed pipeline even when a water feed tank 19 is allowed to fall during the spray feed of water and a water feed impossible state is eliminated. Further, a washing solution does not flow back to the air feed pipeline during the feed of water.
