Title: Treatment of fluorine containing waste water
Inventor: INOUE SHIRO
IPC: C02F1/58
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To sharply reduce fluorine-containing waste water without sludge generation and to recover distilled water of high purity by adding alkaline water solution before evaporative concentration to keep the vaporization of hydrofluoric acid brought by the evaporation of water to a minimum. SOLUTION: To fluorine-containing waste water, water solution of caustic soda is added from an injection device for water solution of caustic soda. Next, the waste water is evaporated and concentrated by an evaporative concentrator. By this concentration, the quantity of the concentrate is sharply reduced and also most of the water is recovered as distilled water The vaporization of hydrofluoric acid brought by the evaporation of water is kept to a minimum. In this case, when the neutralized waste water is concentrated by the evaporative concentrator, the deposition of NaF occurs where solubility as NaF is exceeded to lower the efficiency of equipment. Then, pH of the concentrate leaving the evaporative concentrator is detected by a pH sensor, and based on the detection signal, the added quantity of water solution of caustic soda is controlled.

Title: Sterilization composition
Inventor: EGUCHI YASUTERU
IPC: A61P31/04
Filed: 1978-07-14
Abstract: PURPOSE: A sterilization composition that contains a compound forming active oxygen and a quaternary ammonium salt, thus increasing germicidal power.  
     CONSTITUTION: Said composition contains 0.1W50 wt% of a compound forming active oxygen as hydrogen peroxide and 0.05W30 wt% of a quanternary ammonium as benzethonium chloride. These compounds are hardly effective on Staphylococci when solely used but they develop the synergism when combined to kill effectively them and prevent the suppuration of wounds and burns. When necessary, other ingredients as nonionic surface active agent or agents to prevent the deccomposition are added thereto. The quaternary ammonium salt keeps bubbles of oxygen stable, thus increasing germicidal power.

Filed: 1981-06-04
Abstract: PURPOSE:To generate no black line on the end part of a received picture, by always sending a white signal as for a part of constant width of both ends of an original, irrespective of a result of read.

Also, when a one-shot circuit 4 is triggered by a signal obtained by frequency-dividing the pulse signal generated by the oscillator 2, a signal phiX for deciding a picture nondetecting range is obtained. In case when it is desired to set the number of picture elements of 1 line portion to 2048 and to whiten the width corresponding to 16 picture element of the end, a binary counter of 11 bits is used. When the signals phiT, phiX are inputted to the binary counter 11, a gate 9 is controlled so as to output a white signal of 16 picture element portion, read information of 2016 picture element portion, and also a white signal corresponding to 16 picture elements.

Title: Semiconductor device
Inventor: NAITO TAKAHIRO
IPC: H01L23/50
Filed: 1988-04-08
Abstract: PURPOSE:To enhance package reliability by a method wherein the packaging section of a lead for surface mounting is tapered toward its end in a semiconductor device provided with surface-mount packaging leads so that there will be no solder-caused short circuits between leads during the packaging process. CONSTITUTION:In a semiconductor device outer lead 55, the diameter l2 at a location, nearer to a package 1, of a package section 55A is smaller than the diameter l3 at the lead base, and the diameter l1 at the point of the package section 55A is smaller than the diameter l2. As compared with a design wherein the outer lead diameter is equal (l3=l2=l1) throughout the length, the distance may be larger in this design between two package sections 55A, which contributes to reducing solder-caused short circuits between package sections 55A. This eventually improves the package in its reliability.

Title: Output circuit
Inventor: ACHINAMI MASAYOSHI
IPC: H03K17/04
Filed: 1990-03-30
Abstract: PURPOSE:To prevent the current amplification factor of a transistor constituting an output circuit from being degraded by adding a circuit, which is equipped with a constant voltage characteristic at the same degree as pressure resistance between the base and emitter of the transistor to supply a current to a load, to the TTL type output circuit. CONSTITUTION:A serial circuit composed of a Zener diode 11 and a resistor 12 is connected between an output terminal 1 and a ground terminal 9. The Zener voltage of the Zener diode 11 is made equal with the pressure resistance of an element to be protected such as a transistor (a), diode 6 in the Figure (a), the pressure resistance between the base and emitter of the transistor 4 in a figure (b) or the pressure resistance of the diode 6. Therefore, the PN join of the Zener diode 11 is formed by the same process as PN join between the base and emitter of transistors 4 and 10 or the PN join of the diode 6. The resistor 12 prevents an excess current from flowing to the Zener diode 11 and selects the value of several hundreds OMEGA at a certain degree not to damage the constant voltage characteristic.
