Inventor: SUZUKI TAKEOMI
IPC: G02B27/40
Filed: 1981-02-27
Abstract: PURPOSE:To realize the splitting of the luminous flux transmitted through an image forming lens without dependency upon polarization by using elements which have respectively independent optical axes by each photodetector, split said luminous flux at the wave surface and conduct the respective split luminous fluxes to their appertaining photodetectors. CONSTITUTION:The luminous flux 15 coming from an image forming lens is bisected of its wave surface by the pupils of two lenses 11, 12, and the split luminous fluxes are made incident to respective photodetectors 6', 7'. A phase plate 14 is for providing a constant optical path difference between the 1st and 2nd photodetector arrays. The lenses 11, 12 and the plate 14 may be molded of respectively independent blank materials or may be molded in one body together with the two out of the three or the three. Since the luminous flux is split at the wave surface by the pupils of the lenses 11, 12 in this way, the splitting of the luminous flux is realized without polarization dependency and wavelength dependency. Much better results are obtained if a nontransparent barrier wall 16 is provided.

Title: Production of liquid crystal display element
Inventor: JINGU KEIJI
IPC: G02F1/1333
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To obtain a high polymer dispersion type liquid crystal display element by subjecting a pair of substrates to various kinds of working stages, then subjecting the substrates to a reaction stage of high polymerization. SOLUTION: The substrates constituting the high polymer dispersion type liquid crystal display element are subjected to various kinds of working then to the reaction stage of the high polymerization by light energy or heat energy. Namely, the substrates are subjected to various kinds of such working by which the stresses in the substrate direction are applied thereon, then to the reaction stage of the high polymerization. In the case the end faces of, for example, glass cells are subjected to cutting (generally known as corner cutting), the glass cells are subjected to thus cutting, then to the necessary treatments, such as washing and thereafter, the glass cells are subjected to the reaction stage of the high polymerization by inducting a photopolymerization reaction.  The high polymer dispersion type liquid crystal display element is produced by such sequence, by which the normal state is immediately restored and the occurrence of haze is averted as the substrate is in the liquid state before the polymn. reaction even if the orientation direction is temporarily disturbed by application of the stresses in the substrate direction at the time of corner cutting.

Abstract: PROBLEM TO BE SOLVED: To extend the life of a contact pin and to enhance the reliability of actuation during insertion by providing a spring part with a pawl part, providing a core part with a cut part in which the pawl part fits, and fitting the pawl part into the cut part. SOLUTION: A spring part 13 has a C-shaped cross section, is fitted over a core part 12, and has contact pats 14 at two positions. Because of the C- shaped cross section of the spring part 13, all of burrs produced by press working are formed inside, i.e., on the end face of a through hole. A pawl part 15 is formed at the spring part 13, and a cut part 16 in which the pawl part 15 fits is provided in the core part 12 of a contact pin. By fitting the pawl part 15 into the cut part 16, the rotation of the spring part 13 is stopped by the cut part 16, and the spring part 13 is secured to the core part 12. Thus the burrs are prevented from being caught by the end face of the through hole during insertion, and the rate at which the spring is turned up is reduced.  Also, a C-shaped cross section is more excellent than an S-shaped cross section in terms of rigidity, and the permanent set of the spring can be prevented.

IPC: H04R29/00
Filed: 1981-02-27
Abstract: PURPOSE:To achieve a measuring device for a speaker which can determine the optimum reference static location of an oscillation system, by measuring the change in a sound pressure frequency characteristics to the change in the reference static location of the oscillating system to a magnetic circuit. CONSTITUTION:A speaker 4 to be measured is connected to an amplifier 2 connected to an AC power supply 1 via a capacitor 3, and a series circuit of a resistor 5 having a sufficiently higher value than the impedance of the speaker 4 and a DC power supply 6 is connected in parallel with the speaker 4. In an anechoic room 7 in which the speaker 4 is measured, a microphone 8 is arranged opposingly to the speaker 4, and the output of the microphone 8 is recorded with a recorder 9. In measuring the sound pressure versus frequency characteristics of the speaker 4, a synthesized current of AC and DC flows to the speaker 4, and the oscillating system of the speaker 4 is oscillated by shifting the reference static location by the DC component. Thus, if the reference static location is optimum can be discriminated by comparing the sound pressure and distortion  factor according to the amplitude of the direct current.

Inventor: HASHIMOTO KOSUKE
IPC: G09F13/04
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To offset distortion inherent in a magnifying lens without forming distortion on a display surface by bending and curving a flat magnifying lens at assembling time so as to offset distortion possessed by the magnifying lens. SOLUTION: A curved lens 3 by curving a peripheral part of a flat one-sided convex lens 2 in a cylindrical surface shape to the image display plate 1 side, is arranged as a magnifying lens to magnify and remotely display an image display plate 1 by turning a curved convex side to the eye point I side. When the peripheral part of the one-sided convex lens 2 whose convex surface is turned to this eye point I side is curved in a cylindrical surface shape to the image display plate 1 side, since high power is produced in the peripheral part, pin-cushion distortion is generated.  As a result, since pin-cushion distortion is imparted to a magnified virtual image 4 so as to offset barrel distortion C by curving the one-sided convex lens 2 as the curved lens 3, even if the one- sided convex lens 2 having barrel distortion C is used, a magnified virtual image A having no distortion can be visually observed.

Abstract: PURPOSE:To prevent the flying about in different directions and flowing out of dust, and powdered earth and sand which form mountainous deposits by mixing blast furnace granulated slag fine powder and rotary furnace slag fine powder at the specific rate of their weight to form a surface coating material. CONSTITUTION:Blast furnace granulated slag fine powder and rotary furnace slay fine powder having alkali stimulating effect are mixed at the ratio of (95:5) to (5:95) in their weight, and water is then added to them, and the above resultant material is coated on the surface of deposits 1 of dust and powdered earth and sand as a slurry shaped coating material. The blast furnace granulated slag fine powder undergoes alkali stimulation to make its components dissolve by force of its property, and produces a CaO-SiO2-H2O system hydrate and then hardens. Further, even if the above blast furnace powder does not undergo the alkali stimulation, CaO dissolves to rise its PH, and the above blast furnace powder thereby reacts hydratedly on each other to harden. Dust and powdered earth and sand which form the deposits can thus be prevented from flying about in different directions and flowing out.
