Title: Picture projection device
Inventor: SAWAI YASUMASA
IPC: G03B33/12
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To obtain a projected picture whose luminance is high by enhancing illumination efficiency and projection efficiency. SOLUTION: Illumination light emitted from a light source 301 is guided to light valves 201-203 by an optical integrator consisting of a first lens array 303 to a second lens array 308, a superposing lens 309, a relay optical system 310, a prism body 311 and the rear group 502 of a projection lens 5 being the telecentric optical system. Besides, the illumination light is split into plural secondary light sources by the optical integrator. Then, the images of the light sources are formed at the diaphragm position of the lens 5 by the optical system 310 and the mirror 311 and emitted toward the valves 201-203 in a telecentric state thereafter. By constituting the reflection member of the illumination light by using the prism body 311 consisting of a reflection prism, reflection loss is reduced and the vignetting of projection light caused by the reflection member is eliminated.  Thus, the illumination efficiency and the projection efficiency are enhanced.

Abstract: PURPOSE:To improve the working efficiency and prevent the occurrence of wrong insertion of backup pins by automating the operations that hold and take out the backup pins from a housing box and inserts the backup pins into prescribed hole on a setting plate. CONSTITUTION:When backup pin transferring conditions regulated by the dimension, etc., of a printed board 14 are inputted, a controller drives a movable table 10, positions backup pins 180 housed in a backup pin housing box 17, and makes a pin holding section 21 to hold the pins 180. Then the controller moves the table 10 so as to position a hole 119 of a setting plate 11 immediately below a holding section 21 and inserts the pin 180 into the hole 119 by lowering the section 21 by actuating an elevating/lowering mechanism 22. After a prescribed number of pins 180 are inserted into the prescribed number of holes of the plate 11 by repeating the above-mentioned operations, a substrate 14 is placed on the backup pins 180 through guide rails 15 and 16. Therefore, the working efficiency can be improved and, at the same time, the occurrence of wrong insertion can be prevented.

Title: Inspecting apparatus for appearance
Inventor: KAKIGI GIICHI
IPC: G01N21/956
Filed: 1990-11-07
Abstract: PURPOSE:To reduce an excessive detection of defects by setting a suitable reference value from experience for the case where defects of a wiring pattern of a printed circuit board is detected and the degree of the defects are stored in a multivalued data and comparing the degree with a reference value. CONSTITUTION:A coding circuit 28 forms a radial code RC, and stores the radial code corresponding to the position of a binary image of the wiring into a radial code memory 32 only when a center detecting circuit 26 detects the approximate center of the wiring. An address of a defect degree ROM 36 is designated by the code RC, thereby turning the apparatus into the read state. The degree of defects D corresponding to the code RC is stored in a multivalued data in an address RC of the ROM 36. In the meantime, a reference value setting device 38 sets a reference value S by a dial or the like, and a digital comparator 40 compares the degree of defects D read from the ROM 36 with the reference value S. When D>=S, the wiring pattern at the measuring position is detected to be defective. Therefore, since the suitable reference value S is set from experience, an excessive detection of defects can be restricted.

Title: Production of solvent for dye used for pressure sensitive paper
Inventor: HASEBE SHINJI
IPC: B41M5/165
Filed: 1988-11-30
Abstract: PURPOSE:To easily obtain a solvent for dye used for a pressure sensitive paper having an extremely high solubility to the dye and high quality by a method wherein a raw material anthracene oil freed from crystal which has been subjected to specified rough distillation is subjected to acid cleaning, and is then subjected to specified hydrogenation and specified precise distillation. CONSTITUTION:An anthracene oil freed from crystal and having a nitrogen concentration of about 7,000ppm is subjected to rough distillation in the temperature range of 290-360 deg.C, and is then subjected to acid cleaning to have a nitrogen concentration of about 4,000ppm, followed by hydrogenation with a hydrogenation degree of 1-8 to obtain a hydrogenated product with a nitrogen concentration of 100-2,000ppm. The hydrogenated product is subjected to precise distillation in the temperature range of 250-350 deg.C to obtain a fraction with a nitrogen concentration of 10-200ppm. The rough distillation removes unnecessary fractions, and alleviate the load at the time of the hydrogenation. The acid cleaning removes basic nitrogen compounds, whereas the hydrogenation removes hetero-atoms, and simultaneously achieves hydrogenation of nuclei, thereby increasing the fluidity of the product. By the precise distillation, it is possible to remove lighter fractions having strong odors and heavier fractions which would worsen the hue of the product, from the product.
