Title: Slide film image reader
Inventor: KOYAIZU MASAAKI
IPC: G03B21/00
Filed: 1989-05-25
Abstract: PURPOSE:To detect a slide film without providing a switch for detecting the slide film by providing hole parts which are blocked when the slide film is inserted in a holding mechanism. CONSTITUTION:When the slide film 10 is inserted in the holding mechanism 11, the pole parts 11f and 11g are blocked. Therefore, when reading starts, a photoelectric conversion element 16 does not detect light passing through the parts, but reading the image of the film 10 is started. The image of the film 10 is read by the light transmitted from a power source 14 via the conver sion element 16. On the other hand, when the film 10 is not inserted in the holding mechanism, the hole parts 11f and 11g are not blocked. Therefore, when the reading starts, the conversion element 16 detects the light passing through the parts, and reading the image of the film 10 is stopped. Thus, whether the film 10 is inserted or not is detected through the use of the light source 14, the conversion element 16, and the holding mechanism 11, and conse quently, the switch to detect the slide film is not needed.

Title: Humidifier using steam
Inventor: OTA KENJI
IPC: F24F6/00
Filed: 1988-05-30
Abstract: PURPOSE:To stabilize humidity control with high accuracy for a long time, by shortening opening time of a solenoid valve for blowing service and minimizing the quantity of discharge water at a time in such manner that the inflow of cold water from a water supply tank may not stop the generation of steam. CONSTITUTION:The water supplied form the outside by way of a water supply pipe 1 flows into a water supply tank 3 by way of a float valve 2. The supply of water continues until it goes up by a heater 4 in a vapored water tank 8. When the water reaches a predetermined water level, the water supply will come to a halt by a valve packing pushed against a water supply port by the buoyant force of a float. Then, when heating advances and humidification steam is generated, vaporized residuals in the supply water are accumulated in the vaporized water tank 8. The opening time of a solenoid valve 7 must be shortened based on the application of a timer 5 and the solenoid valve must be more frequently opened and closed and the quantity of discharge water at a time must be reduced in such a manner that the inflow of cold water from the water supply tank 3 to the vaporized water tank 8 may not stop the generation of stem if it is desired to pre;vent the increase in the concentration without halting the quantity of humidification.

Abstract: PROBLEM TO BE SOLVED: To detect a correct concentration of a gas without time and labor required for maintenance by introducing a gas into an optical path between a light emitting part for emitting lights containing two wavelengths and a detector having a filter adapted to pass the lights alone to absorb or transmit the lights with these wavelengths. SOLUTION: Light emitted from an infrared emitting element 2a is transmitted through a glass 1j of a partition wall 1c, then, introduced into an introduction path 1h to be irradiated to carbon dioxide and subsequently transmitted through a glass 1k of a partition wall 1d. The light transmitted through the glass 1j reaches detectors 3a and 3b but that with a specified wavelength is detected as filters 3c and 3d are provided. When the lights with these wavelengths irradiate the carbon dioxide, the lights are absorbed according to the concentration thereof, which allows detecting of the concentration of the carbon dioxide based on the light with the wavelength detected by the detector 3a. At this point, even when the glass 1j is fouled, correction is possible based on the light with the wavelength detected by the detector 3b without being irradiated to the carbon dioxide to be absorbed.
