Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To enhance a telecentric characteristic with respect to white light by constituting a positive and a negative lenses so that the Abbe's number of the materials thereof become mutually different. SOLUTION: The white light radiated from a light source 1 is reflected on a reflector 2 so as to form the picture of the light source at the end surface of an integrator 3. By the integrator 3, the picture of the light source formed at the entrance thereof is divided into the plural pictures. By the first lens group of a relay lens 4, the picture of the light source is uniformly formed again at the position of a diaphragm 5. This picture is the second light source picture. Then, the light from the second light source picture is enlarged by the second lens group II and the Fresnel lens 6 of a reflector lens 4 and made into luminous flux whose directions are slightly different every respective colors R, G and B by a color resolving system 10 so as to illuminate a liquid crystal display device 7.  The average Abbe's number of the materials of the positive and the negative lenses in the second lens group II are different. The colored picture displayed by respective pixels R, G and B is enlarged and projected on a screen 9 by a projection lens 8.

Abstract: PURPOSE:To reduce thrust by forming the outer circumferential part of a roller on which a flat belt 4 is laid, of a resilient layer in which a plurality of short fibers oriented in the radial direction of the roller, and exposing a part of the short fibers from the resilient layer. CONSTITUTION:A photosensitive belt 4 is laid on a plurality of roller members, wherein the cylindrical member 2b of one of follower rollers 2 is formed as a resilient layer made of rubber in which short fibers F are mixed.

Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To stably measure RGB electronic beam positions with high precision at the adjustment of color CRT convergence.

Title: Oil pressure relieving device of automatic transmission
Inventor: IWATANI YOSHIMI
IPC: F16H61/08
Filed: 1988-11-15
Abstract: PURPOSE:To prevent speed change shock in the initial period of rising, by allowing a certain oil pressure to be applied to No.2 pressure receiving part of No.2 spool, which performs strokes through the action of the regulated oil pressure given by No.1 spool of a pressure regulating valve, and eliminating this application of oil pressure when a specified motion is attained. CONSTITUTION:When a shift valve is switched to cause supply of oil pressure from an oil path 34 to a one 30, oil pressure to a clutch 8 rises abruptly, and its attainment of a specified value causes the oil pressure at a poor 16 to balance with the force of a spring 14, and No.1 spool 10 is put in pressure regulated condition, and oil pressure from ports 25, 26 actuates leftwise stroke of No.2 spool 12. This compresses the spring 14 to boost the oil pressure on the oil path 30 to be regulated by the No.1 spool 10, and closing of the port 25 by a minor dia. land 12b of the No.2 spool 12 causes exhaustion of the oil pressure at No.2 pressure receiving part from a drain port 24, which allows only the oil pressure at the port 26 to act on the No.2 spool 12 so that the oil pressure on the oil path 30 is boosted slowly. This accomplishes reducing generation of speed change shocks.

Abstract: PURPOSE:To secure the rapid valve opening action of a high pressure valve and improve assembling property and safety by providing a top-like high pressure valve which can close a high pressure side inlet port and a high pressure side outlet port simultaneously on one side while which can close a low pressure side port on the other side. CONSTITUTION:By electrifying a motor-driven element 52, a crankshaft 54 is rotated, causing a pressure drop in the low pressure chamber 61 of a compression chamber 60. A top-like high pressure valve 77 which can close a high pressure side inlet port 72 and a high pressure side outlet port 74 simultaneously on one side while which can close a low pressure port 76 on the other end face, is provided in a valve cylinder 75. And, even though the clearance between the valve 77 and the valve cylinder 75 is relatively rough, since the high pressure side inlet port 72 is closed, the pressure drop can be securely carried out in a short time. As a result, the pressure difference between pressure in an enclosed container 51 and pressure in the valve cylinder 75, acts on the top-like high pressure valve 77, enabling secure and rapid valve opening action of the valve 77. And, the good assembling property an safety of the top-like valve 77 can improve productivity.

Abstract: PURPOSE:To shorten a transaction time and reduce trouble such as a jam which is inevitably caused at the time of separation by providing a 1st money paying means which pays previously counted and packed cash and a 2nd money paying means which pays cash that is counted at the time of payment. CONSTITUTION:A payment mechanism part 14a separate bills from a storage box by an amount that a customer requests at each time and conveys them to a reception opening 4. A payment mechanism part 14b conveys a belted ticket of specific metal of, for example, 100,000 yen or 200,000 yen to a reception opening 7. Further, two reception openings for coins are added; and a mechanism which conveys a rod of coins or coins of a specific amount is provided at one added reception opening and a mechanism which conveys an optional amount of money is added at the other reception opening. Thus, the belted ticket or rod of coins is discharged by the 1st money paying means and bills or coins of a fractional amount can be paid by the 2nd money paying means. Consequently, a large amount of cash can be taken out of the storage box directly without being separated and counted, and then conveyed to the reception opening, thereby greatly shortening the wait time of a user.
