Title: Silver halide photographic sensitive material
Inventor: TAKEMURA KUMIKO
IPC: G03C1/12
Filed: 1990-06-23
Abstract: PURPOSE:To enhance sensitivity and to reduce color stains due to residual dyes by adding a liquid containing a spectral sensitizing dye and iodide to a silver halide emulsion to execute spectral sensitization. CONSTITUTION:The spectral sensitizing dye, such as cyanine dyes, merocyanine dyes, composite cyanine dyes, composite merocyanine dyes, holopolar cyanine dyes, hemicyanine dyes, styryl dyes, or hemioxanol dyes, is used, and any ring usually used for the cyanine dyes and pigments as a hetero ring can be used for these dyes. The spectral sensitization is executed by adding the liquid containing both of these spectral sensitizing dye and the iodide to the silver halide emulsion, thus permitting sensitivity and sharpness to be enhanced and color stains due to residual dyes to be reduced.

Title: Speed-adjustable degree wafer exchange robot
Inventor: ABUI TETSUPUMAN
IPC: B65G49/07
Filed: 1994-07-18
Abstract: PURPOSE: To raise the speed of a wafer exchanging system by operating a drive means at the first speed or acceleration when a wafer support retains a wafer, and operating a driver at the second speed or acceleration higher than it when the wafer support retains the wafer. CONSTITUTION: A robot retains a wafer on one occasion while moving from one place to other place, and it moves without retaining the wafer on one occasion. That is, it moves, holding the wafer 11 from a litter to a process chambers 26, 28, 30, or 32, and it is drawn out in vacant condition from the chamber so as to process the wafer within the chamber. Then, a computer supplies a step motor with pulses at quick ratio when the wafer support is vacant. Then, when the wafer support carries the wafer slowly, it supplies the step motor with pulses at slow ratio.

Title: Production of quartz glass fiber
Inventor: ARAI TAKICHI
IPC: C03B8/02
Filed: 1987-07-03
Abstract: PURPOSE:To reduce cutting of fiber by tension during burning and enable production of a continuous quartz glass fiber having high strength, by storing gel-like fiber for a specific term after forming the fiber in production of quartz glass fiber by burning gel-like fiber. CONSTITUTION:A solution of silicoalkoxide is hydrolyzed and a gel-like fiber is formed from the solution in gelation reaction. After the gel-like fiber is formed, the fiber is stored for 1hr-10 days and then burned. Since the gel-like fiber which is porous silica gel formed from the above-mentioned solution is hydrolyzed in reaction with water content in atmosphere and further subjected to polymerization by the above-mentioned storage, strength and density thereof is gradually raised. The effect is hardly exhibited in storage within 1hr and when the storage term exceed 10 days, organic substance in the gel-like fiber is not completely gone in burning or filament arrangement between plural numbers of single fibers constituting gel-like fiber sometimes gets worse, because the density becomes too large.

Though the work piece side is rough, the light 8 is again bent to reach a screen 9 by the existence of the oil film 15 and a projection point 10 is dropped in a position apart from the axis 5.  An operator moves the work piece 1 until the axis 5 is aligned with the projection point 10, and fixed to the mount 3 by solidifying an adhesive 2, the reflector 13 is retreated, and a chuck 4 is rotated to work the work piece in a designated shape by a grinding wheel 16.
