Abstract: PURPOSE:To enlarge an adequate visual position to enable an observer to well observe stereoscopic videos by constituting the above device in such a manner that the distance from the surface of a first lenticular plate to a diffusion part is not equal to the product of the refractive index of lenticular lenses constituting the first lenticular plate and focal length. CONSTITUTION:The position of the diffusion surface 10 aligns to the focal position of the lenticular lenses 9 and pixel images 11 are extremely fine when the thickness t1 of the lenticular lenses 9 on an incident side (the distance from the surface of the lenticular plate to the diffusion part) is defined as t1=n1.f1 (n1, f1 are respectively the refractive index and focal length of the lenticular lenses 9). The position of the diffusion surface 10' is, thereupon, set at a position of approximately t1' from the incident side end of the lenticular lenses 9 by setting the thickness t1' at t1'=t1/2 so as not to attain t1=n1.f1. Consequently, the width p' of the pixel images 11' formed on the diffusion surface 10' is about half the width (pitch) (p) in the horizontal direction of the lenticular lenses 9 and the sum of the widths of the pixel images projected from two units of projectors is 2p'=p.

Filed: 1981-03-05
Abstract: PURPOSE:To facilitate the checking work, to shorten the working time, and to perform highly reliable check, by providing a soft insulating plate on one of two facing plate parts for holding a conducting wire to be measured, and providing two conducting plates having the conducting wires on the other plate part. CONSTITUTION:A main body 1 is formed by an upper plate 2 and a lower plate 3 comprising an insulating material. The upper plate has the insulating plate 4 and the lower plate 3 has metal pieces 5.

IPC: H04N1/60
Filed: 1986-02-14
Abstract: PURPOSE:To attain accurate color reproduction by obtaining an area of black, blue, magenta and white at each picture element in applying color reproduction with respect to a stimulous value of an original picture. CONSTITUTION:In the color hard copy forming a picture while applying ink on paper, the distribution of ink film IM is produced in response to the color of the applied ink such as yellow, magenta, cyan, red, green, blue or black, and the ink film IM has a different light transmissivity depending on the color.

Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of the tracking control of a traveling truck for a material to be carried so as to always perform stable tracking control by calculating speed correction quantity based on deviation between a carrying distance and a traveling distance and performing speed control for the tracking of the traveling truck with respect to the carried material. SOLUTION: The carrying distance Lb of the tail end of a material 2 to be carried is measured based on a pulse number detected by a pulse transmitter 8 attached to a feed roller 6. Based on a pulse number detected by a pulse transmitter 5 attached to a driving motor 4, a distance Lm from the traveling start of a traveling truck 1 is measured. A distance Ld from the position X0 of the traveling truck 1 is calculated from the sum of the distances L1 and Lm. Deviation of a distance between the carrying distance Lb of the tail end of the carried material 2 and the traveling distance Ld of the traveling truck 1 is calculated by a subtracter. A speed correction quantity obtained by a function generator using the deviation as an input is added to the speed reference value of the truck driving motor 4 by an adder 19 and thereby speed control is performed for the traveling truck 1.

Title: Extension system for half-duplex multidrop transmission line
Inventor: MAEDA TATSUYA
IPC: H04L12/40
Filed: 1983-02-28
Abstract: PURPOSE:To extend a transmission line which is controlled by an HDLC procedure with simple circuit constitution without degrading responsiveness by interposing an extending device which checks the transmission direction of a received data frame and driving data to a specific line while stopping a driver/receiver which is not used for transmission in the transmission line. CONSTITUTION:The data frame F1 from a line A is sent to a selecting circuit S1 through the receiver R1 of the extending device 5. The circuit S1 checks the direction code C of the frame F1 to judge whether the data is a processor 1 or not. When so, the receiver R2 is disconnected from a driver D1 and the frame F1 is transmitted to a driver D2, which is driven to a line B. At this time, the frame F1 is not sent back to the line A. When the data is not from the processor 1, the selecting circuit S1 does not send this signal to the driver D2. A frame F2 from the line B is the same. Thus, driving is performed without the absence of data.

IPC: G05B19/42
Filed: 1986-02-17
Abstract: In a photoelectric apparatus for tracing a scanning head (8) along a pattern track (13), a constant arrangement (17) of tightly spaced light-sensitive elements (16) is provided in the scanning head forming together with an addressing device (25) scanning patterns (14) which can be sampled.

The shape and/or the position of the scanning pattern (14) in the scanning head scanning the pattern track (13) may be varied by selective sampling of determined light-sensitive elements from a greater number of light-sensitive elements (16) provided in the constant area-like arrangement (17).

Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To efficiently remove a coating film without generating dry spot on the surface of a base material by using an aq. solution containing hydrogen peroxide and potassium hydroxide in a specific concentration. SOLUTION: A removing agent contains over 5 wt.% potassium hydroxide in addition to hydrogen peroxide. The TiAlN-coating film is removed from a member coated with the coating film without generating the dry spot on the surface of the base material by dipping the member into the removing agent for 30-60 hr. When the temp. of the removing agent is <10 deg.C, the removing rate of the coating film is lowered and when the temp. of the removing agent exceeds 80 deg.C, the concentration of the removing agent is rapidly changed by the self-reaction of removing agent to make unable to keep the removing rate. Then, the treatment with the removing agent is desirably executed at 10-80 deg.C, particularly >=40 deg.C. The concentration of hydrogen peroxide in the removing agent is preferably 0.1-60% though not particularly limited.
