Title: Keplerian view finder
Inventor: OSHITA KOICHI
IPC: G02B13/18
Filed: 1989-09-14
Abstract: PURPOSE:To attain synthetically excellent performance even with small-sized and simple constitution by permitting the focal distance of a positive lense component, which faces its convex plane that has more curvature to the iris side, and the distance of a positive lens component, which faces its convex plane to a subject, to satisfy the specified conditions. CONSTITUTION:The finder is provided with an objective lens O composed of the positive lens component O1, which faces its convex plane that has move curvature to the iris side and the positive lens component O2, which faces its convex plane to the object side, and an eyepiece E, which includes the positive lens component, in order from the object side. The following inequalities are satisfied; 0.4<f1/f2<1.2, where f1 is the focal distance of the positive lens component O1 in the objective lens and f2 is the focal distance of the positive lens component O2. Thus, even with the small-sized and simple constitution, the Keplerian view finder with the excellent aberration correction is attained.

Title: Power plant
Inventor: MACHIDA MASAHITO
IPC: F02C3/28
Filed: 1992-09-08
Abstract: PURPOSE:To prevent any noxious gas from occurring as well as to improve the extent of reliability in equipment by installing a bypass pipe which branches high pressure gas out of a furnace from the upstream side of a cutoff valve, feeding it to an exhaust pipe of an expansion turbine, and thereby lowers the extent of pressure in the furnace. CONSTITUTION:When trouble has occurred in a power plant, both first and second cutoff valves 5 and 6 are closed, and a compressor 1, an expansion turbine 2 and a furnace 4 are all interrupted. Since a first control valve 13 is opened and high pressure gas left behind in space between the second pipeline 9 of the furnace 4 and the second cutoff valve 6 is fed to an exhaust pipe 16 of the expansion turbine 2 by way of a second bypass pipe 12, pressure in the furnace 4 is decompressed. Simultaneously, since a second control valve 15 is opened, and compressed air left remaining in space between the furnace 4 of the first pipeline 8 and the first cutoff valve 5 is fed to the second bypass pipe 12 by way of a third bypass pipe 14, high pressure gas passing through the second bypass pipe 12 is cooled by the compressed air. Thus, any noxious gas is prevented from occurring, and the extent of reliability in equipment is improvable.

Title: Customer data adding/changing control system
Inventor: HASEGAWA IWAO
IPC: H04M3/00
Filed: 1991-09-19
Abstract: PURPOSE:To provide a suitable service by switching from customer data to be referred to customer data to be added and changed when time data are coincident to period data. CONSTITUTION:When time data prepared from a time data preparing means are not coincident to period data stored in a memory block MEM 5, after one minute passes, it is investigated whether or not the time data prepared from the time data preparing means again are coincident to the period data stored in the memory block MEM 5. When it is judged that the time data to be prepared are coincident to the period data to be stored, a central control unit rewrites the content of a memory block MEM 4 to '0', and when the name of the memory block stored in a memory block MEM 3 is MEM 2, the content of the memory block MEM 3 is rewritten to the name of the memory block MEM 1 and at the time of the MEM 1, the content is rewritten to the name of a memory block MEM 2.

Title: Optical fiber clamping mechanism
Inventor: YANAGI AKIRA
IPC: G02B6/24
Filed: 1988-09-26
Abstract: PURPOSE:To clamp optical fibers with optimum force by constituting a pressing means for pressing the fibers to plural V-grooves in such a manner that the pressing force thereof can be varied. CONSTITUTION:A change lever 69 is moved downward to press the rear surface of a flange part 67c of a 2nd sleeve 67 to the front surface 63c of a flange part 63c of a supporting arm 63 in case of clamping the multiple optical fibers 60. The spring forces of a compression spring 68 and a tension spring 64 act downward on the supporting arm 63 at this time. An operator moves the change lever 69 upward to press the same to the rear surface of the flange part 67a of the 2nd sleeve 67 and further lifts the 2nd sleeve 67 upward in case of clamping the single optical fiber 67. Only the spring force of the tension spring 64 acts on the supporting arm 63 at this time and lifts an upper block 62 downward. Single to plural pieces of the optical fibers can be held by the adequate pressing force in this way and, therefore, the correct axis alignment and fixing are executed.

Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To eliminate a need for a fear of the automatic feed of water to a water gathering pan and the presence of water in a tank when a humidifying function is provided without modifying an air-conditioner. SOLUTION: A part of air blown out through the air outlet of an air- conditioner by inclining a flap is inputted and when inputted air passes through a humidifying element, humidity of air is increased. The humidifying element is placed on a water gathering pan and water is fed to the water gathering pan from the water tank by a pump 23. A water level sensor 32 is arranged at the water gathering pan. When a no water signal is received by a control part 31 from the water level sensor 32, the pump 23 is driven for a given time and a given amount of water is automatically fed to the water gathering pan. When the control part 31 receives a no water signal for a given time in succession, it is decided that water runs out in the water tank and a lamp 34 is lighted ON to notify a utilizer.

Title: Light quantity filter and its production
Inventor: FUKAZAWA TOSHIO
IPC: G11B7/135
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To obtain a light quantity filter which is good in the accuracy of a transmitted light quantity and phase difference and is decreased in variations by forming a thin-film layer in the recessed part side part of a difference in level formed on a substrate adjacent to an optical element, thereby varying the transmitted light quantity between a projecting part and the recessed part. SOLUTION: This filter has the difference in level on the substrate 1 adhered adjacently to the optical element. The thin-film layer 4 consisting of a metallic thin film is formed on the recessed part 2 of the difference in level and an antireflection film 5 is formed in order to make the transmitted light 100% in the projecting part 3 of the difference in level. The transmitted light 7 past the projecting part 3 of the difference in level of the cast incident light 6 is 100% in transmission efficiency and the transmitted light 8 past the recessed part 2 of the difference in level is attenuated in the transmitted light quantity by the absorption of the thin-film layer 4 and, therefore, the transmitted light quantity of the thin-film layer 4 is varied. The transmitted light 7, 8 vary in the phases by a quantity 9 of the difference in level.  Then, the elimination of the phase difference between the transmitted light 7 and 8 by the transmission through the thin-film layer 4 is made possible by adjusting the quantity 9 of the difference in level. The arbitrary setting of the phase difference is possible as well and the correction of the astigmatism difference of lasers is also made possible.
