Title: Cobalt analyzer
Inventor: MIZUNIWA FUMIO
IPC: G01N33/20
Filed: 1981-03-26
Abstract: PURPOSE:To determine 1ppt cobalt by making use of the coloring of an alkaline soln. from absence of color to a yellow color when cobalt exists in said soln. where 1,2-dihydroxybenzene-3,5-disulfonic acid coexist with hydrogen peroxide. CONSTITUTION:Sample water is introduced into a valve 3 through a sample water introduction piping 2 branched from part of a sampling piping 1. The buffer soln. in a tank 5 is fed through a flow passage 3C to a mixer 7. The 1,2-dihydroxybenzene-3,5-disulfonate in a tank 8 and the hydrogen peroxide soln. in a tank 9 are introduced by constant flow pumps 10, 11 into the mixer 7. While the mixed solns. from the mixer 7 pass through a reaction coil 12 kept at about 50 deg.C by a water bath 13, the 1,2-dihydroxybenzene-3,5-disulfonate are oxidized by the hydrogen peroxide in the presence of cobalt, and color to a yellow color having max. absorption at 440nm.

Title: Ordinary-temperature solid phase joining method
Inventor: KAIHARA SHOICHIRO
IPC: B23K20/00
Filed: 1989-02-23
Abstract: PURPOSE:To easily carry out solid phase joining of materials to be joined by making temperature conditions to the comparatively low temperature including the ordinary temperature and holding pressure conditions in an inert gas atmosphere below the atmospheric pressure and then, applying the pressurizing force which does not cause deformation on the materials to be joined whose joining surfaces are physically activated. CONSTITUTION:The temperature conditions are made in the temperature range of the ordinary temperature to 250 deg.C considerably low as compared with diffusion joining and in addition, the pressure conditions are made in the range below the atmospheric pressure including a vacuum and the periphery is set in the inert gas atmosphere containing inert gas such as Ar or <=10ppm O2. Under these conditions, the joining surfaces of the materials to be joined are then activated by the physically activating method such as high-frequency electric discharge, ultrasonic oscillation and surface friction. The joining surfaces of the materials to be joined are then fitted to each other in a stationary state and the pressurizing force which does not cause deformation on materials to be joined is applied to join the materials to be joined. By this method, the materials to be joined are subjected to solid phase joining without bringing these in high-temperature conditions as in the case of diffusion joining and besides, without requiring the high pressurizing force like press welding.

Title: Power source abnormality detecting circuit
Inventor: MATSUFUJI NORIYASU
IPC: G01R19/165
Filed: 1989-02-23
Abstract: PURPOSE:To detect with high accuracy abnormality when the power failure occurs at a commercial power source by detecting a range in which positive and negative voltages of AC exceed a threshold by a generation pulse of a switching element, and deriving the time between them by counting a reference clock pulse. CONSTITUTION:When a voltage ES of an AC power source 1 is inputted to photocouplers 7, 8, the couplers 7, 8 emit a light beam in accordance with positive and negative of the voltage ES, respectively, and output a voltage EP. The voltage EP is amplified by an amplifier 10, and a voltage EO whose waveform is inverted is generated. To a counter 11, the voltage EO and a reference pulse of a clock 12 are applied. Based on these signals, the counter 11 counts the number of pulses in rise and fall periods of the voltage EO, and inputs it to a microcomputer 13. The microcomputer 13 stores this value in an internal register 14, and also, discriminates whether abnormality exists or not. Unless abnormality exists, the counter 11 is reset and with regard to each cycle of the next voltage EO, the same operation as the foregoing is executed, and abnormality of the power source is decided.

Title: Temperature measuring method
Inventor: HONDA TATSURO
IPC: G01J5/00
Filed: 1989-02-23
Abstract: PURPOSE:To accurately measure the temperature of even a surface to be measured which is composed of a scattering surface and a specular surface by finding the P- polarized component and S-polarized component of heat radiation on the scattering surface and calculating the emission brightness of a reference light source at temperature equal to that of the surface to be measured. CONSTITUTION:Reference light with emission energy QP0 and emission energy QS0 of the P-polarized component and S-polarized component emitted by a reference light source 1 is intermitted by a chopper 2 and projected on a sector mirror 9. The mirror 9 rotates to transmit or reflect incident light. The transmitted light is reflected by the surface 3 to be measured, passed through a polarizer 9, and detected by a radiation thermometer 7. Its detection output is sent to an arithmetic unit 11 to calculate the emission brightness Eb of the reference light source at the same temperature with the surface 3 from an equation, thereby finding the temperature of the surface 3. In the equation, QP and QS are measured values of the P-polarized component and S-polarized component of the sum of reflection energy to be referred to and emission energy by heat radiation on the surface 3 in the direction of the specular surface and EP and ES are the measurement outputs of the P-polarized light component and S-polarized light component of the heat radiation energy by the heat radiation on the surface 3 while the reference light is cut off.

Title: Inspecting method for flotation of fitted body
Inventor: TSUGE OSAMU
IPC: G01M99/00
Filed: 1988-02-26
Abstract: PURPOSE:To inspect whether or not a body is accurately fitted to the fitting surface of a cabinet by forming conductive parts on the fitting surfaces of the cabinet and the body to be fitted to the cabinet and measuring the electric resistance between the conductive parts. CONSTITUTION:Layers which can be fed with electricity are provided on the fitting surfaces (e) and (f) of the cabinet 2 and fitted body 1. When the cabinet 2 and fitted body 1 are securely fitted, the gap (c) between the fitted body 1 and a switch 4 is of original size. At this time, the resistance between them is minimum because there is no gap between the layers (e) and (f). If, however, there is a gap between the fitting surfaces of the cabinet 2 and fitted body 1, there is a gap between the layers (e) and (f), so the resistance between them is maximum. Thus, the electric resistance between the layers (e) and (f) is measured by a measuring instrument 5 to easily and securely inspect whether or not there is a gap between the cabinet 2 and fitted body 1.
