Title: Semiconductor etching apparatus
Inventor: NOJIRI HIDETOMO
IPC: H01L21/306
Filed: 1986-06-30
Abstract: PURPOSE:To obtain a smooth and accurate etching surface by circulating the etchant between a first bath for etching semiconductors and a second bath communicating with the first bath and provided with means for separating and collecting the reaction products in the first bath by reducing action. CONSTITUTION:When Si semiconductor substrates 4, held by a wafer holder or the like, are dipped in an etchant 5 in a first bath 1, an etching treatment of the wet etching type proceeds. At this time, reaction products are generated by ethcing of the semicoductor substrates 4 and they are dissolved into the etchant 5, but the etchant 5 containing the reaction products is moved to a second bath 2 by a circulation means. In the second bath 2, due to the electric field generated between positive electrodes 7a-7c and negative electrodes 8a-8c, the reaction products are captured by the negative electrodes 8a-8c, and they are separated and collected by the reducing action of the negative electrodes 8a-8c. The etchant 5 rid of the reaction products returns back to the first bath 1 through a circulation pipe 11.

Title: Digital analog converting method
Inventor: KOBAYASHI OSAMU
IPC: H03M1/10
Filed: 1986-06-30
Abstract: PURPOSE:To reduce an output error at the time of applying D/A conversion by converting an input code by a prescribed method, then applying D/A conversion to the result. CONSTITUTION:A new code is generated from an external code di according to a prescribed algorithm. In such a case, the input code is subject to code conversion by applying SRT division by '1' or the equivalent obtaining the identical result. Then an input voltage VIN is fetched from an input terminal IN in the sampling state at D/A conversion and an output voltage VOT is sent from an output terminal OT. The control is executed by giving an internal code ai (=1,0,-1) as a control input. Thus, with the input code di changed, the possibility of an error in the least significant digit exists, but other digits are unchanged and a differentiation nonlinear error is minimized.

In this case, since the space 4 is communicated to the front by the through hole 6, the river water is allowed to enter the space 4, creating an environment in which aquatic insects and plants and the like can live.  Since the space 4 is communicated to four sides by the open part 5, the water, insects, and fishes are allowed to freely enter and exit, and the water is purified by bacteria living in the space 4. Therefore, an excellent ecology for creatures to live in can be constructed.

Filed: 1988-06-20
Abstract: PURPOSE:To obtain the above rubber compsn. having a remarkably improved heat build-up effect by compounding a reinforcing filler and a specified heat build-up modifier to a natural rubber or a diene synthetic rubber. CONSTITUTION:The title rubber compsn. is obtd. by compounding 100 pts.wt. rubber consisting of a natural rubber and/or a diene synthetic rubber with 20-150 pts.wt. reinforcing filler and 0.1-10 pts.wt. one or more members selected from among 2-substd. imidazole compd., phenylenediamine compd. and formaldehyde condensates. The heat build-up modifier to be sued can be easily used by mixing a 2-substd. imidazole compd. and a phenylenediamine compd. in methanol and adding therein formaldehyde at 50-55 deg.C. This modifier can be used alone or two or more thereof can be used. If the loading of the reinforcing filler (e.g., carbon black) is less than 20 pts.wt., the reinforcability of the rubber compsn. is inferior and, if it exceeds 150 pts.wt., it is not pref. because the heat build-up improving effect becomes small and physical characteristics such as wear resistance becomes remarkably inferior.

Title: Spatial light modulation element
Inventor: SHIMIZU SHIGEO
IPC: G02F1/1343
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To improve the color reproducibility without sacrificing the brightness by forming a low reflection region in the side region of a pixel electrode for a red color along the pixel side adjacent to a pixel electrode for a blue color. SOLUTION: The reflection electrode 81 consists of pixel electrodes 81a, 81b,... each consisting of a group of pixel electrodes for three color light of R, G, B in an array state, and a low reflection region 20 is formed in a part of the region along the pixel electrode for the R color adjacent to the pixel electrode for B color. The effective R light which can be used as projecting light is present only in a short wavelength region, and the region where the low reflection region 20 is to be formed is illuminated by light in the long wavelength R region which is not visible by human eyes. Therefore, even when the light in the long wavelength R region is not used as the projecting light, the intensity of the R light does not substantially decease.  Even when blue light is overlapped and illuminated on the R pixel electrodes due to the alignment error, this region is formed as a low reflection region 20 so that the light does not cause deterioration in the color reproducibility. Therefore, the color reproducibility of R light can be increased without sacrificing the brightness.
