Title: Sliding vane type rotary compressor
Inventor: TAKESHITA KOUJI
IPC: F04C18/344
Filed: 1980-11-14
Abstract: PURPOSE: To prevent clearance leak at the end of a vane by installing more than one section having the radius of curvature approximately identical to the outside diameter of rotor along the inner peripheral surface of a cylinder over a vane's pitch angle of 50% and greater.  
     CONSTITUTION: The inner surface of a cylinder 5 consists of two arcs having radius R1 and R2. This radius R2 is made larger than the outside radius R of a rotor 7 by 0.01W0.02mm. The range α of arc formation is equalized with the pitch angle of a vane 8 in a rotating direction from the rear side of a discharge port 6. This construction eliminates the generatin of space between a cylinder 5 and a rotor 7 which was hitherto observed. The gas leaked from a clearance T is filled into the space sealed by a sliding vane 8b and equalized with the discharge pressure, thereby preventing further leakage. Therefore, clearance leakage can be prevented in this manner.

Filed: 1982-09-17
Abstract: PURPOSE:To receive a trigger signal and to generate a release signal only when a photographic lens is focused, by receiving a signal from a trigger signal generating means and a focus detection signal receiving means. CONSTITUTION:In case that the focusing mode is selected, the focus signal outputted from an automatic focusing device A is detected when the photographic lens is in focus, and a gate group 18a outputs an H signal in accordance with this detection. If another mode is not selected, an AND gate 23 outputs the release signal to a camera to perform photographing at the time, when the gate group 18a outputs the H signal, because all other inputs of the AND gate 23 are H. This mode is used for the purpose of performing automatically photographing at the focus time when a moving object passes a position where the focus state is attained in the state where the object field distance of the photographic lens, namely, the position of a focusing lens is fixed. The same may be said for other cases. as the result, proper photographing is always performed.

Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To constitute the element distribution in the depth direction from the surface as population inversion, by constituting the constituent elements of a first metal layer as elements whose ionization potential is lower than the constituent elements of a second metal layer, constituting the constituent elements of the second metal layer as elements whose ohmic property is more excellent than the constituent elements of the first metal layer, and performing heat treatment after the layers are laminated. SOLUTION: A first metal layer 81 is formed by forming an Ni film of 10-200Å in thickness on a P<+> layer. A second metal layer 82 is formed by forming an Au film of 20-500Å in thicknes on the first metal layer 81. After the Ni film and the Au film are laminated, heat treatment is performed. Au in the second metal layer 82 on the first metal layer of Ni is diffused in the P<+> layer 7 through the first metal layer 81, and forms the state of alloy with GaN of the P<+> layer 7. That is, the distribution of Au and Ni in the depth direction is changed before and after the heat treatment. During the heat treatment, elements in the first metal layer travel the vicinity of the surface. As the reaction, elements of the second metal layer are alloyed with group III nitride semiconductor, and permeate into the semiconductor. Thereby population inversion is realized.
