Title: Radiation thermometer
Inventor: HISHIKARI ISAO
IPC: G01J5/10
Filed: 1990-08-29
Abstract: PURPOSE:To secure compatibility without selecting a converter for each detector by providing a memory section storing the standardized correction data to correct the fluctuation of characteristics determining the temperature output on the detector. CONSTITUTION:When the detecting element 4 of a detector 1 detects the radiation energy of a measured object W via an optical system 3, the detection signal is amplified 5 to the preset level and A/D-converted 6 then inputted to an arithmetic section 8. The detection signal inputted to the arithmetic section 8 is corrected and calculated for the fluctuation of characteristics based on the coefficient value data of a memory section (ROM) 7 to obtain the standardized output V(T). Code data are superimposed on this output, and it is fed to a conversion section 2 via an I/F conversion section 9. The conversion section 2 arranged at a position apart from the field decodes the code data and automatically performs the calculation peculiar to the detector 1 such as the change of the linearized arithmetic equation. The fluctuation of characteristics is corrected and calculated, thus compatibility can be secured without selecting a converter for each detector 1.

Title: Compressor
Inventor: OKUDA MASAYUKI
IPC: F04C18/107
Filed: 1989-08-31
Abstract: PURPOSE:To prevent dislocation of the motions at both ends of a component on the revolving side by dividing a piston and a blade in the center in axial direction, fitting an Oldham ring between piston divisions, and coupling together the piston divisions. CONSTITUTION:Feeding current to a motor 1 rotates a cylinder 3 together with a rotor 2, and the rotational motion is transmitted to a piston 6 via a pin 35, Oldham ring 5b, and square column 32. The piston 6 keeps the condition of partially contacting with the internal circumference of the cylinder 3 under motion control of the Oldham ring 5b and revolves round the axis A of the cylinder 3 while rotation round its own axis in synchronization with rotation of the cylinder 3. Because the Oldham ring 5b is installed in the middle axially of the piston 6, a force to control the revolving motion is transmitted simultaneously to both sides of the piston 6, which is thus free from twisting and prevents leakage of the refrigerant gas between working chambers each other, which should enhance the compression efficiency.
