Title: Rotary compressor
Inventor: KOYAMA MASAHARU
IPC: F02F1/18
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To use as a cylinder of a rotary compressor a cast iron which is excellent in wear resistance and workability and made by using a sand mold together with a chiller. SOLUTION: In a compressor using as a cylinder a cast iron made by machining using a sand mold casting method, the material of the cylinder at those areas where cutting work is required is eutectic graphite base (ferrite base F) partially. Thus the workability of a vane slot groove is increased and the amount of wear on the sliding surface of a vane disposed in the vane slot groove is reduced.

Title: Restart system in data transmission equipment
Inventor: OMORI SHIGERU
IPC: G06F13/00
Filed: 1985-11-30
Abstract: PURPOSE:To automatically perform a restart operation after the recovery of a power source without performing the setting of input/output data and an initialization with a software by preparing the power source backup for an input/output data area, and preserving the input/output data stored at the input/ output data area when the power source of a controller at a main body side is cut off. CONSTITUTION:A data is transferred between an information controller 2 and plural local units LU1, LU2,..., LUn through a main body side controller 4. At an input/output memory 21 for the input/output data where the input/output data area Dlm of the main body side controller 4 is allocated, a logic circuit voltage Vps and a backup voltage VBB for a backup power source 23 are inputted through a diode OR circuit 24. Thereby, since the backup voltage VBB is supplied even when the logic circuit voltage Vps is cut off by a power failure, the input/output data stored at the input/output data area Dlm is preserved without being dissipated.

Title: Blade for cross fan
Inventor: TAKADA YOSHIHIRO
IPC: F04D29/30
Filed: 1986-11-14
Abstract: PURPOSE:To promote the orientation to a low noise, by forming a blade in a corrugated shape providing protrusions and recesses in trailing edge, central and leading edge parts of the blade in its span direction. CONSTITUTION:An impeller of a cross flow fan is formed by driving side plates 10, reinforcing side plates 11 and blades 6. The blade 6 forms its trailing edge part, providing a rugged part in a blade span direction, to be corrugated. Accordingly, a systematic further rapid growth of turbulence, generated from a shearing jet flow in a pressure surface side, can be prevented. Consequently, the impeller, which is insensitive for a flow direction in the suction side preventing exfoliation from being generated in the span direction as in a two-dimensional blade, enables the orientation to a low noise to be promoted.
