Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To ensure a return loss more than a specified value in an electromagnetic wave absorber, which is formed into a sheet shape, by a method wherein the volume filling rate of a soft magnetic metal powder of an aspect ratio lower than a specified value to a matrix, the thickness of a sheet and a frequency region are respectively selected in a specified range to select the volume filling rate of the metal powder, the thickness of the sheet and the frequency region according to a frequency region to contrive to make the peak of the return loss position. SOLUTION: Powder of an aspect ratio lower than 2 is used as soft magnetic metal powder, such as sendust powder, Permalloy powder, Fe-Cr alloy powder, Fe-Cr-Al alloy powder and Fe-Cr-Si alloy powder, which is used for forming an electromagnetic wave absorber. The volume filling rate of the soft magnetic metal powder to a matrix, the thickness of a sheet and a frequency region are respectively selected within the range of 18 to 32%, within the range of 1.3 to 3.5 mm and within the range of 6 to 20 GHz to select the volume filling rate and the thickness according to a frequency region to contrive to make the peak of a return loss position. Thereby, an electromagnetic wave absorbing sheet ensuring an attenuation more than 20 dB and of 22 to 25 dB as the value of the return loss can be obtained.

Title: Scroll compressor
Inventor: TOUSHI HIROSHI
IPC: F04C18/02
Filed: 1981-03-04
Abstract: PURPOSE:To raise the efficiency of a scroll compressor, by empolying such an arrangement that an outlet port is located on the inside of a movale lap at the final stage of compression and high-pressure gas is allowed to enter into the next enclosed space only from the starting end of scroll of the movable lap. CONSTITUTION:As turning motion proceeds, the starting end A of scroll of a movable lap 1a comes out of contact with a fixed lap 2a, so that high-pressure gas in an enclosed space 3 flows into the next enclosed space 12' from the portion of the starting end A of scroll. In this final stage of compression, that is, until the starting end A of scroll of the movable lap 1a comes out of engagement with the fixed lap 2a, high-pressure gas in an enclosed space 12 never flows into the next enclosed space 12'. Therefore, it is enabled to reduce the top clearance and hence to minimize the pressure loss of the compressor.

IPC: H03K3/84
Filed: 1979-03-19
Abstract: PURPOSE:To simplify the circuit constitution and then decrease the types of the power sources by forming the peak value detecting circuit with the capacity and the resistance. CONSTITUTION:With making of the power source, the outputs of FF2-6 forming the shift register all become 1, and the output becomes 0 for the peak value detection circuit consisting of resistance 8 and capacitor 9.
