Title: Optical fiber radiation thermometer
Inventor: YOSHINAGA RYOICHI
IPC: G01J5/00
Filed: 1990-04-03
Abstract: PURPOSE:To secure the optical path to a body to be measured even in a narrow place and a place where measurement environment is inferior and to accurately measure the temperature and emissivity at the same time by transmitting two spectral radiation brightness signals which differ in conditions from the body to be measured to a photodetector by using an optical fiber. CONSTITUTION:The optical fiber 2 transmits the radiation brightness from the body 1 to be measured to the detector 3. The best spectral radiation conditions (wavelength and polarization) for the body 1 to be measured can be selected by the detector 3 and two spectral radiation conditions are easily obtained. A parameter input part 41 inputs the parameter of the relational equation between two known spectral emissivity values which correspond to the two selected spectral radiation conditions and are characteristic to the body to be measured to an arithmetic part 5 and a parameter input part 42 inputs the parameter of a black body furnace calibration function showing the relation between the spectral radiation brightness signal of the detector 3 and real temperature to the arithmetic part 5. The arithmetic part 5 finds the real emissivity on the emissivity function which is the function between the two corresponding spectral emissivity values from the two spectral radiation brightness signals to find the real temperature at the same time.

Title: Manufacture of granulated material
Inventor: HESSE WERNER DR
IPC: B22F1/10
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To obtain a good injection molding material without executing a preliminary mixing between a hard material phase and metal powders by specifying the viscosity of a binder. SOLUTION: At least one kind of the hard material phase is mixed with the metal powders and the binder to form granulated powders. At this time, the preliminary mixing between the hard material phase and the metal powders is not executed before the hard material is mixed with the binder. The binder has a viscosity of 20 to 200cm<3> /10min. at 195 deg.C and under a load of 2.16kg by the DIN standard. Mixing with the organic binder having such a high viscosity brings a high shearing force into a mixture and, as a result, flocculation of the hard material phase or metallic component particles is dispersed or cannot be generated. Therefore, the components inside the granulated material are uniformly distributed, which is reflected to the characteristic corresponding to a produced molded member.  Thus, also the flow characteristic of the granulated material during the injection molding is improved, thus the molding of complicated members is facilitated, thereby shortening the binder removing time, too.

IPC: G01R31/00
Filed: 1989-04-10
Abstract: PURPOSE:To achieve a higher workability of an AC noise test by comparing one of a plurality of reference voltages preset and an AC noise voltage which is inputted after dividing the output of a noise generator through a connection means of the apparatus. CONSTITUTION:Impulse noise voltage across a resistor R1 is applied to series resistors R2 and R3 through a capacitor C1. Here, the C1 is a decoupling capacitor and employs a high voltage element. When an impulse noise divided to be inputted exceeds a slice level V1 selected, a comparator 21 generates an output signal of 'L' level (OV), which is supplied to a clear terminal CL of a flip flop 22 to generate an output signal holding a voltage of a 'L' level. When the signal of 'L' level is supplied to a preset terminal PS of the flip flop 22, it is inverted to return to an 'H' 1 level. As an output of the flip flop 22 goes to an 'L' level, current flows through a light emitting diode 23 to emit light.
