Title: Method for electrolyzing brine
Inventor: MURAKAMI KATSUYUKI
IPC: C25B1/26
Filed: 1982-03-18
Abstract: PURPOSE:To prevent the reduction of current efficiency after restarting in intermittent operation when sodium hypochlorite is manufactured by electrolyzing brine, by supplying an electric current for maintenance during the suspension of electrolysis. CONSTITUTION:NaOCl for disinfection used in a water purification plant is obtd. by electrolyzing brine using an anode formed by coating a Ti substrate with a Pt group metal and/or its oxide and a cathode made of iron, an iron alloy or Ti. In this case, the suspension of electrolysis is unavoidable. When the supply of an electric current is suspended for a certain time and started again, the current efficiency is temporarily reduced in accordance with the kind of the anode material, so an electric current for maintenance is supplied at 0.05-0.5A/dm<2> current density during the suspension of electrolysis. As a result, reduced current efficiency can be restored within several min after restarting.

Title: Resistor and manufacture thereof
Inventor: TORIGOE KAORU
IPC: B05D5/12
Filed: 1991-03-07
Abstract: PURPOSE:To control the resistance value of a resistor formed by baking paste for forming the resistor after the paste is applied to a substrate with a thin glass film in between by printing and heat-treating the formed resistor. CONSTITUTION:The resistance value of a resistor film formed on a substrate with a thin glass film in between can be increased by utilizing such a phenomenon that the glass component of the glass thin film is diffused into the resistor film when the resistor film is heat-treated. The resistance of the resistor can be precisely controlled when careful attention is paid to such heat-treating conditions as heat-treating temperature, heat-treating time, etc., and, usually, when the heat-treating conditions become stronger, the diffused amount of the glass component from the thin glass film into the resistor film and, accordingly, the resistance value of the resistor film increase. It is not necessary to raise the heat-treating temperature higher than the melting point of the glass, since the diffusion of the glass component takes place even when the temperature is lower than the melting point.

Title: Laser radar equipment
Inventor: WAKABAYASHI SATOSHI
IPC: G01S7/491
Filed: 1983-03-14
Abstract: PURPOSE:To make the use of two laser oscillators and an acoustic optical modulator unnecessary, to save an electric power, and to make the whole device small in size by using a laser oscillating circuit which executes an oscillation continuously by single longitudinal and lateral modes, and also whose frequency can be tuned. CONSTITUTION:An output light of a laser oscillator 1 of frequency f0 passing through a beam splitter 6 is made incident to a laser amplifier 3, and immediately after a transmitting light 8 is emitted by a pulse operation of said amplifier, a command is given to a frequency controller 13 by a timing controller 14, and the frequency of the laser oscillator 1 is varied to f0 before a reflected light 9 is made incident to a detector 7. f0' is set so as not to become equal to fo+fd which considers a Doppler shift frequency fd in case when an object moves. When the frequency of the laser oscillator is varied alternately to fo and fo', an optical heterodyne detection of a reflected light 9 can be executed every time. In this way, two laser oscillators are not required, and an acoustic optical modulator which consumes a large electric power and requires cooling water is unnecessary, therefore, the device can be made small in size.

Title: Medium separation mechanism
Inventor: MORI TAISUKE
IPC: B65H3/52
Filed: 1986-02-28
Abstract: PURPOSE:To allow one-sheet separation feed and allow to cope with the difference in thickness by utilizing the difference of the friction factor among a roller, a belt, and a medium via a feed roller and a belt having no driving system in a sheet/card-like medium separation device. CONSTITUTION:The inner peripheral length La+Lb of a belt 5 is longer than the peripheral length of a fulcrum friction roller 11 and a friction roller 12, and the belt 5 forms some contact angle with a feed roller 4. When the first sheet of medium 1 enters between the roller 4 and belt 5 the belt 5 acts to attain La=Lb, and the first sheet of medium 1 is pinched between the feed roller 4 and belt 5 by a force Fb generated by the force Fa of a spring 10 via an arm 13. The medium can be easily separated due to the difference of the friction factor among the medium, roller, and belt. Accordingly, the belt can be displaced with no driving source, the medium is separated in one sheet by a spring with no adjustment, a change of thickness can be coped with, and economical efficiency, operability, and reliability can be improved.
