Title: Back washing method for condenser
Inventor: KATAKURA KAZUO
IPC: F28G9/00
Filed: 1986-12-01
Abstract: PURPOSE:To contrive an efficient operation and a shorter back washing time, by back-washing small-diameter cooling pipes in two water chambers of a condenser which has independent cooling water systems, through operating inlet and outlet valves for the water chambers and connecting valves between the chambers with appropriate timings under the condition where one of the cooling water systems is stopped. CONSTITUTION:When an outlet valve 2A for a water chamber A is opened and a connecting valve 6 is fully opened from an opening for operation in a serial operating condition (forward washing), a condenser is set into a single-chamber operation in which only forward washing in the water chamber A is performed. When a connecting valve 7 between the inlet side of the water chamber A and the outlet side of a water chamber B is opened, forward washing is performed in the water chamber A, while back washing is performed in the water chamber B by introducing water through the valve 7 and discharging it through a connecting valve 5. When an inlet valve 1A for the water chamber A is then closed, the condenser is set into a single-chamber operation in which only back washing in the water chamber B is performed. When the outlet valve 2A for the water chamber A is closed and one back wash valve 4A is opened to an arbitrary opening, water is permitted to flow sequentially through the connecting valve 7, the water chamber B, the connecting valve 5, the water chamber A and the back wash valve 4A, resulting in back washing in both of the chambers A, B.

Title: Support structure of center of gravity matching for mechanical apparatus
Inventor: NAKAMURA KATSUSHIGE
IPC: G12B9/08
Filed: 1990-10-29
Abstract: PURPOSE:To facilitate the center of gravity matching for a mechanical apparatus so easily as well as to secure an accurate support structure by supporting the machinery and equipment within a second inner ring being free of unification with a second outer ring. CONSTITUTION:A mechanical apparatus 1 is supported by a second inner ring 7b of a second rotating bearing part 7. At this time, the center of gravity of this mechanical apparatus 1 is not accorded with the center of the second rotating bearing part 7, therefore the mechanical apparatus 1 rotates together with the second inner ring 7b, so the center of gravity is situated just under the center of the second rotating bearing part 7. Then, the second rotating bearing part 7 is shifted upward to a first rotating bearing part 8 in the vertical direction together with the mechanical apparatus 1, through which the center of gravity of this mechanical apparatus 1 is accorded with the center of the first rotating bearing part 8. With this constitution, the center of gravity matching has completed in consequence, and since there is no variation in the center of gravity even if the mechanical apparatus 1 is rotated, it is left stopped intact at a position where it was stopped, thus any possible unbalancing at the side of a supporter 6 will not happen there too. With this constitution, it is made supportable in the state that the center of gravity is made to coincide.

Title: Surface light source element for liquid crystal display device
Inventor: ODA MASAHARU
IPC: G02F1/1335
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To obtain high luminance and the high uniformity of the luminance within the light exit surface of a light transmission body without subjecting the surface to a treatment for making the surface uniform by forming at least either the light exit surface or rear surface of the light transmission body of a rough surface having ruggedness of an average angle of inclination and specifying the degree of variation on the light exit surface to below specific value. SOLUTION: This surface light source element comprises a light source and the light transmission body having at least one light incident surface and the light exit surface approximately orthogonal with this surface. At least either the light exit surface or rear surface of the light transmission body of such surface light source element is formed of the rough surface having the ruggedness of 0.5 to 7.5 deg. average angle of inclination (θa). The degree of variation (R%) of the luminance on the light exit surface of the light transmission body is <=20%. If the average angle of inclination (θa) of the ruggedness is below 0.5 deg., the exit angle of the exit light increases and the direction of the exit light to a normal direction is no longer possible in spite of use of an angle changing member. If, conversely, the angle exceeds 7.5 deg., the uniformity of the luminance as the surface light source element of the liquid crystal display device is impaired.
