    • This invention relates to a fault diagnosis system for hydraulic pumps in a work vehicle, which is economical and permits sure identification of one or more trouble-developed ones of the hydraulic pumps.Pressure sensors 61-64 are arranged on pressurized fluid lines 30,40, which extend to a tank T from points immediately out of center bypasses of flow control valves 21,231-234,451-454,26 communicated to hydraulic pumps 1-6. Solenoid-operated directional control valves 51-56 are interposed in input circuits of individual regulators 11-16 so that, upon excitation, a pressure of a pilot pump 7 is introduced into the regulators 11-16. When all the flow control valves are brought into neutral positions thereof and a determination is instructed through a switch 80, one of the solenoid-operated directional control valves is excited by a signal from a processor 70 so that pressurized fluid is delivered at a maximum flow rate from the corresponding hydraulic pump. A detection value of the corresponding pressure sensor at this time is translated into a flow rate, which is then stored. These procedures are performed with respect to the individual hydraulic pumps successively. Based on a flow rate obtained in every determination, a fault diagnosis of the corresponding particular hydraulic pump is performed.

    • A latent heat accumulation system uses latent heat for air-conditioning. The latent heat accumulation system includes a tank, supplying section, injecting section, drawing section and collecting section. The tank has a liquid storing section for storing Fluorinate (trade name) in the lower portion thereof, storing water which is cooled by ice via a boundary surface with Fluorinate in the middle portion thereof and storing the ice together with the water in the upper portion thereof. The supplying section supplies the water into the liquid storing section. The injecting section injects Fluorinate cooled to a preset temperature into the water stored in the liquid storing section. The drawing section draws out the water which is stored in the liquid storing section and cooled by the ice to the exterior of the tank as an air-conditioning heat accumulation medium. The collecting section collects a mixed fluid of the water and Fluorinate from the lower portion of the liquid storing section.

    • An image reader is disclosed which is provided with a screen for an image recorded on a microfilm to be projected thereon and a photoelectric transferring element for transforming the image into electric signals. In a light path originating in a light source and reaching the photoelectric transferring element, a beam attenuating filter for attenuating the luminous energy of the beam of light exposed on the photoelectric transferring element is disposed and used for decreasing the difference in the illuminance of the light source during the reader mode for causing the image to be projected on the screen and during the transforming mode for causing the image to be exposed on the photoelectric transferring element. The illuminance of the light source is controlled by the variation of the intermittent frequency of the voltage applied to the light source. While the operation is proceeding in the transferring mode, the illuminance of the light source is controlled with the aforementioned intermittent frequency falling within the range of sonic frequency so as to permit variation of the illuminance of the light source in a multiplicity of stages. While the operation is in this mode, the sound of the movable components of the device being operated for scanning cancels the noise generated within the range of sonic frequency.
