Title: Swash plate type compressor
Inventor: SAEKI MANABU
IPC: F04B39/00
Filed: 1994-06-09
Abstract: PURPOSE:To reduce the occurrence of delivery pulsation by a method wherein a first communication passage from a delivery chamber on the rear side is not communicated with an external discharge port but with a discharge chamber on the front side and a second communication passage from the discharge chamber on the front side is not opened to the discharge chamber on the rear side but communicated with the external discharge port of a compressor. CONSTITUTION:A discharge chamber 24 on the rear side is communicated with a discharge chamber 23 on the front side through a first communication passage 27. Further, the discharge chamber 23 on the front side is communicated with the external discharge port 25 of a compressor through a second communication passage. This constitution first expands a compressed refrigerant, discharged from the cylinder on the rear side of piston cylinders 7a-7e, the discharge chamber 24 on the rear side. The compressed refrigerant is expanded again in the discharge chamber 23 on the front side as it is throttled by the first communication passage 27. Compressed refrigerants discharged from the cylinders on the front side and the rear side and joined together in the discharge chamber 23 on the front side are communicated with the external discharge port 25 through the second communication passage and discharged. As noted above, the pulsation component value of a high pressure refrigerant is reduced through expansion of the two discharge chambers 23 and 24, throttle in the first and second communication passages 27 and 28, and interference operation in the first communication passage 27.

Filed: 1990-05-17
Abstract: PURPOSE:To allow the intricate change of light quantity by providing plural transparent parts or reflecting parts formed randomly in accordance with the information on the coincidence quantity corresponding to a desired change of the light quantity obtd. by using random numbers in the direction where a substrate is used. CONSTITUTION:The random numbers 0 to 1 for the number of the basic patterns to be formed in a prescribed position are generated by a computer at the time of forming the basic patterns of the transparent parts (reflecting parts) for light quantity control. If, for example, the desired value of the transmission quantity (or reflection quantity) in this prescribed position is 30%, the transparent parts (or reflecting parts) are formed in this prescribed position only when the value of the random numbers generated at this time is <=0.3. For example, metallic films 1 (chromium films) of a very small circular shape (dot) are formed by a photoprocess atop a glass substrate 2 and such substrate is used as the optical element for light quantity control. The intricate and fine change of the light quantity is possible in this way.
