Title: Scroll compressor
Inventor: SAWAI KIYOSHI
IPC: F04C18/02
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To properly feed sealed oil to a compression chamber via an oil passage, even upon the occurrence of a drop of the feed volume of refrigerating machine oil during a low-speed operation by positioning the inlet of the oil passage formed on the driven shaft of a revolving scroll lower than the center of the circular cross section of the driven shaft. SOLUTION: When a scroll compressor is operated, refrigerating machine oil contained in a sealed vessel 1 is pumped up on the operation of an oil pump 15 and supplied to a scroll compressor mechanism via an oil passage 26 at the center of a crankshaft 10. At this process, a part of the refrigerating machine oil separated at the end of a revolving scroll shaft 9 is blown out via an oil passage 27 at the center of the driven shaft 9 of the revolving scroll 2, and an oil passage 28 having a throttle part 29 on an end plate 6. In this case, the oil passage 27 on the driven shaft 9 has an inlet at a position lower than the center of the circular cross section of the driven shaft 9, thereby ensuring that the oil is properly supplied to a compression chamber 8, even upon the occurrence of an oil level drop at the end of the driven shaft 9 during a low-speed operation.

Title: Transmission path array
Inventor: KORAADO DORAGON
IPC: H04B10/43
Filed: 1990-11-22
Abstract: PURPOSE: To make the efficiency of a waveguide array the maximum by containing different Fourier series expansion provided with such a lowest-order term that is decided to meet a prescribed standard in each refracting space cross section arranged at intervals throughout a waveguide array. CONSTITUTION: The smooth shape of each waveguide of a waveguide array can be seen as an infinite chain composed of infinitely small discontinuity which becomes the cause of converting energy to a first unnecessary mode from a basic mode. However, the energy which is converted into the first unnecessary mode from the basic mode by each discontinuity reaches the opened end of the waveguide array at different phases due to the difference of the propagation constant between the two modes. Therefore, the shape of each waveguide is designed so that the phase of the energy converted into the first unnecessary mode by the discontinuity can be evenly distributed between zero and 2. For this purpose, different Fourier series expansion having a set lowest-order Fourier term is contained in each refracting space cross section.  Therefore, when one waveguide is excited in the basic mode, most of radiation power is evenly distributed in a central Brillouin region and a highly efficient waveguide array can be obtained.
