Title: Pulse width modulation output amplifying circuit
Inventor: YOSHIDA TADAO
IPC: H03F3/217
Filed: 1978-05-31
Abstract: PURPOSE:To prevent the power loss at a non-signal time by supplying the input of sound signals to the inversion input terminal to one balanced integrating circuit and grounding the non-inversion input terminal. CONSTITUTION:Sound signals supplied to input terminal 1 are not only connected to non-inversion input terminal + of balanced integrating circuit 2a but also connected to inversion input terminal - of balanced integrating circuit 2b, and further, the + terminal of circuit 2b is grounded. Then, the output of square wave signal generator 7 is supplied to - terminals of circuits 2a and 2b, and these outputs are supplied to amplifiers 5a and 5b through zero-cross switch circuits 4a and 4b respectively and are supplied to speaker 10 through LPF 9. By this constitution, though in-phase square wave signals are obtained in the output side of circuits 5a and 5b at a non-signal time, they are cancelled in the input side of filter 9, and no invalid current is flowed. As a result, power loss can be prevented.

Title: Wet type dust collector
Inventor: AKIBA ISAMU
IPC: B01D50/00
Filed: 1984-04-04
Abstract: PURPOSE:To prevent a pipe of a wet type dust collector from being filled with bubbles by constructing the inside dia. of an upper side of a connecting pipe between a water separator and a washing tank with a small size pipe and that of a lower side of the pipe with a large size pipe to reduce the flow rate of air. CONSTITUTION:Welding fume sucked from a suction port 1 is cooled by a washing liquid 13 from a washing liquid nozzle 2, and the spark is collected on a prefilter 3. Only fine welding fume is led into a long fiber filter section 4 where oil is removed and the fine fume is led into a washing tank 14. Dry fume passes through a water separator 5 and is collected by a cloth filter 11 and falls in a dust tank 12. The washing liquid in a washing liq. tank is discharged from a nozzle by a circulating pump 8, washes the prefilter and the long fiber filter, and the washing liquid is recovered by the water separator. The flow rate of air is reduced by constructing an inlet pipe to have small size (B), and a lower part of the pipe having large size (A), to retard bubbling of the recovered washing liquid to execute recovery smoothly.

Title: Rich-burn sensor
Inventor: ASAYAMA YOSHIAKI
IPC: G01N27/409
Filed: 1983-04-12
Abstract: PURPOSE:To obtain an air-fuel ratio sensor which can detect rich-burn by a method wherein a measurement chamber is equipped with an oxygen control and supply means and a chemical equivalent point detection means and exhaust gas is introduced into this measurement chamber. CONSTITUTION:An oxygen control and supply means is composed of zirconia solid electrolytic plates 11a, 12a and a chemical equivalent point detection means is composed of zirconia solid electrolytic plates 11b, 12b. Measured gas (exhaust gas) is introduced into a space chamber (measurement chamber) B through a fine diffusion hole 14. The difference between the oxygen density in a reference air chamber A' and the oxygen concentration in the space chamber B is detected by the chemical equivalent point detection means. As an output voltage of an oxygen concentration cell which is the chemical equivalent point detection means changes step by step in the rich-side from a theoretical air-fuel ratio point, the theoretical air-fuel ratio point can be detected. Because the quantity of the oxygen introduced into the space chamber B can be optionally controlled by an oxygen pump which is the oxygen control and supply means, the air-fuel ratio can be shifted to the rich-side from the theoretical air-fuel ratio point and the optional air-fuel ratio can be detected.

Abstract: PURPOSE:To obtain solvent-resistant porous fine crosslinked polymer particles of a uniform particle diameter, by allowing specified fine uncrosslinked polymer particles to absorb a noncrosslinking monomer and a crosslinking monomer, subjecting these particles to copolymerization treatment and extracting solvent-soluble matter from the treated particles. CONSTITUTION:Fine uncrosslinked polymer particles (A) are allowed to absorb a monomer mixture comprising 50-90wt% noncrosslinking monomer and 50-10wt% crosslinking monomer and the particles are subjected to copolymerization treatment in an aqueous medium to obtain a precursor of fine crosslinked polymer particles. Solvent-soluble matter is extracted from the obtained precursor (B) to obtain the purpose fine particles. Said fine uncrosslinked polymer particles (A) are obtained by repeating at least three times an operation of increasing the diameters of particles obtained by adding water and a noncrosslinking monomer to an aqueous dispersion of seed particles and subjecting the resulting dispersion to polymerization treatment and using the obtained grown particles as seed particles in the subsequent operation. In this operation, an uncrosslinked polymer obtained by treating a noncrosslinking monomer in an aqueous medium is used as the initial seed particles. These particles have a particle diameter of 0.5-10mu and a standard deviation of a particle size distribution <=0.1mu.

Abstract: PURPOSE: To generate a requisite braking force using a compact configuration by allowing, in non-operating condition, a spring means to displace an engaging means to a position where disengagement is generated from a control lever, engaging a brake shoe with a brake disc, and hindering the shaft from rotating. CONSTITUTION: If current feed to a solenoid 104 is shut off for any reason, a solenoid 104 is put in the non-operating condition, and an engaging member 90 is displaced down by the restitution force of a spring 102, and a parallel pin 86 is disengaged from the bottom edge of a slot 88 to release the displacement restriction for a control arm 70. The arm 70 is displaced in revolution by the restitution force of a spring 60, and brake shoe levers 10 and 12 are displaced in revolution to cause brake shoes 6 and 8 to be engaged with a brake disc 4. The following rotation in the direction of Arrow A of a drive shaft 2 and the disc 4 tightens the engagement between the shoes 6 and 8 and disc 4. A downward displacement of the member 90 causes a latch pole 108 to be engaged with a notch 106.
