Abstract: PURPOSE:To enable the color of a metallic coating surface to be measured, to shorten a necessary measurement time, and to improve measurement accuracy by lighting uniformly an area to be measured and mixing color information light properly by a condenser lens. CONSTITUTION:Reflecting light beams from a sample on a mount table 18 are made incident on an image forming lens 26. The sample is lighted uniformly by 8 light guide tubes 12 arranged symmetrically about the optical axis of the lens 26. Then, when a changeover lever 36 is rotated as shown by an arrow A, the formed image of the sample is formed on an aperture 38 arranged at a position equivalent to a focus plate 30. Then, luminous flux passing through the aperture 38 is refracted by a condenser lens 40 and mixed when entering a photodetecting element 42. The output signal of the element 42 is guided to a photoelectric converting and A/D converting circuit 16. The circuit 16 converts both the output signal of the element 42 and the monitor signal of light source light incident through a light guide tube 14 into digital signals, which are transmitted to an arithmetic and display circuit 50. Consequently, the measurement accuracy of a colorimeter is improved.

Title: Nuclear reactor plant
Inventor: AKIYAMA KOSEI
IPC: G21D3/00
Filed: 1988-02-03
Abstract: PURPOSE: To simplify the construction of a nuclear reactor by providing a feed water supplying means which introduces part of feed water as driving water to a jet pump and introduces the balance of the feed water to a feed water supercharger in the state of the temp. lower than the temp. of the feed water to be introduced to the jet pump.  
     CONSTITUTION: Part of the feed water diverted on the upper stream of a high- pressure feed water heater 27 is supplied from the feed water supercharger 8 into a reactor pressure vessel 1 without being passed through the heater 27 and the balance of the feed water is supplied through the heater 27 to the jet pump 6 in the vessel 1. The temp. of the feed water supplied to the supercharger 8 by a feed water piping 33 is, therefore, lower than the temp. of the feed water supplied as the driving water into the pump 6 by as much as the water is not heated by the heater 27. The temp. difference between said feed water is adjusted to a prescribed value when the opening angle of a venting valve 41 is controlled by a feed water temp. controller 46. The construction of the reactor is thereby simplified without having the need for providing the means for lowering the temp. of the cooling water sucked into the pump 6 into the reactor.

Filed: 1983-02-15
Abstract: PURPOSE:To erase completely the recorded bits without producing remaining signals by setting the width of a beam spot of erasion mode in the direction rectangular to the scanning direction at the value larger than the width of the beam spot of record mode in the same direction rectangular to the scanning direction. CONSTITUTION:When the light beam of erasion mode is generated from a semiconductor laser 1 and condensed on a recording medium 14' via a collimator lens 2, a polarizer 3, a splitter 4, a reflection mirror 5 and a tracking mirror 6, the center of the light beam spot draws a locus and oscillates toward an arrow mark with wobbling. A current of the direction opposite to that of a record mode is flowed to a magnetic coil 8 to form a magnetic field in the opposie direction to the record mode. A ferromagnetic thin film layer 14' is heated up to a temperature equal at least to the Curie point by the energy of an effective light beam spot, and the directions of magnetization of the layer 14' are set at random. Then the layer 14' is cooled as soon as the effective light beam goes away and at the sme time magnetized in the direction opposite to a recorded bit by a magnetic field of the coil 8. Thus the recorded bit is erased.
