Title: Optical fiber with lens
Inventor: NISHIKAWA MITSURU
IPC: G02B6/32
Filed: 1983-09-19
Abstract: PURPOSE:To eliminate the need for an optical axis adjustment and a distance adjustment by fitting a microlens atop of an optical fiber and making projection light into a parallel light beam. CONSTITUTION:An end surface of the optical fiber 7 is set at the focal point of the microlens 8, and the projection light from the optical fiber 7 is made into the parallel light beam. This optical fiber 7 is put opposite to a lens 13 provided atop of an optical fiber 12 having the same structure by using a screw 11 cut in a holder 9 and a connector 16. Consequently, a slight shift in optical axis position between the optical fibers 7 and 12 and variations in the distance between the lenses 8 and 13 are disregarded and the coupling of the optical fibers is facilitated. The optical power coupling between a photodetector and a light emitting element and the wiring of an optical transmission line are rationalized.

Title: Air conditioner
Inventor: SATO KOHEI
IPC: F24F11/02
Filed: 1990-06-29
Abstract: PURPOSE:To obtain comfortable control with a simple structure by providing an outdoor air introducing means in a controller which controls operation of a compressor and a fan. CONSTITUTION:A controller 22 is for controlling operation of a compressor 2 and a fan 13 and a thermostat (an outdoor air introducing means) T2 is arranged outdoors. This thermostat T2 opens when outdoor temperature is higher than 20 deg.C to interrupt power supply from a compressor power source line 23 to a compressor driving circuit 24. Another thermostat (another outdoor air introducing means) T1 arranged in a room opens when room temperature is higher than 12 deg.C to interrupt power supply from the compressor power source line 23 to the compressor driving circuit 24. If the power supply from the compressor power source line 23 is interrupted, the operation of the compressor 2 is also interrupted. As the thermostats T1 and T2 are connected in series, when one of them opens, the above-mentioned power supply from the compressor power source line 23 to the compressor driving circuit 24 is stopped, while the operation of a fan driving circuit continues.

Title: Optical character reader
Inventor: KIZU SHIYUUJI
IPC: G06V10/12
Filed: 1980-12-10
Abstract: PURPOSE:To make the capacity of a lighting light source small, by discriminating if the describing direction of character information is lateral or longitudinal and the location of description, and controlling three moving mirrors based on the result of discrimination. CONSTITUTION:When a mail P being carried reaches a read-in section 11, a discriminating section 16 discriminates the describing direction and the describing position respectively. For example, when the mail P is a mail written in lateral lines, the section 16 supplies the discrimination signal to a selection circuit 32 and the discriminating signal of describing signal of the zip code to a drive section 23 of a moving mirror 22 of a read-in section 17. Thus, the mirror 22 turns for a specified angle. On the other hand, when the mail is a mail written in longitudinal lines, the section 16 supplies the discriminating signal to drive sections, 27, 29 of moving mirrors 26, 28. Thus, the mirror 26 turns by a specified angle to set the sight of read-in, and the mirror 28 turns and follows mails being carried. As a result, the range of lighting for the mail P toward the carrying direction (a) can be narrowed, allowing to achieve small sized capacity of the lighting light source.

Title: Solar battery sealing film
Inventor: TANUMA ITSUO
IPC: H01L31/04
Filed: 1987-07-15
Abstract: PURPOSE:To prevent a sealing film from shrinkage attributable to heat in a module-building process by a method wherein a solar battery module surface protective layer and a sealing film are beforehand formed into a laminate. CONSTITUTION:The EVA for a sealing film should preferably contain a 15-50 weight percent of vinyl acetate, and any organic peroxide to be disintegrated at 100 deg.C or higher for the generation of radicals may be used. A silane coupling agent will be added which will increase the adhesive force between the sealing film and a surface protective material photovoltaic elements. Said materials are placed in a mixer for blending. The mixture is next processed in a calender, which results in a 0.6mm-thick sheet 4. In a film-bonding process, a calender, an extruder, etc., are used, and the sheet 4 in its molten state is outputted successively. The sheet 4, when going through a cooling roller 6 such as an emboss roller, is allowed to be in contact with a surface protective sheet 16, and the two are nipped between the cooling roller 6 and a rubber roller, which produces a sealing film 5 consisting of the sheet 4 and the surface protective sheet 16 bonded to each other.

IPC: B60S1/34
Filed: 1994-07-27
Abstract: PURPOSE:To prevent the intrusion of water and the generation of abnormal noise, even in the case where the dispersion of dimension is generated between a wiper shaft and the external plate of the car body, because of the dimension error of the car body and the change of the kind of the vehicle. CONSTITUTION:A bellows part 33 is formed on a grommet 30 made of rubber, and a water dripping cover 40 surrounding the periphery of the grommet 30 is fixed on a wiper shaft 21.
