IPC: H04B10/50
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To provide the technology to suppress a drive current deviation without causing significant increase in a wiring layout area. SOLUTION: A current source is formed, by including current source transistors (Q1-1 to Q1-n) and current source resistors (R1-Rn), connected in series with the current source TRs. Plural power resistors for supplying a current to each channel via a power pad are connected in series, and each terminal of the resistors connects with the other terminal of the corresponding current source resistors so as to set the resistance of the power supply resistors and the current source resistors in a way that a current condition, when viewed from each current source TR is equal to each other. Thus, all the current flowing to each current source is made identical, to suppress the drive current deviations.

IPC: H03F1/42
Filed: 1978-06-12
Abstract: PURPOSE: To prevent the breakdown of the transistor by cutting the base drive current of the current amplification transistor to be protected when some fault occurs.  
     CONSTITUTION: The forward bias voltage is applied between the base and emitter of transistor Q 6  in the abnormal state under which output terminal b touches (short- circuit) the negative terminal of the power source. As a result, transistor Q 6  operates to cut the base drive current of transistor Q 2  at the upper side of the B-class push-pull step via collector drive current, to cut the base drive current to be injected to the base of end-step transistor Q 4  and to turn off Q 4  respectively. In other words, the abnormal current is prevented from flowing to Darlington- connected current amplification transistors Q 2  and Q 4 , thus avoiding the breakdown of the transistor.

Abstract: PURPOSE:To heighten the horsepower efficiency and combustion efficiency, by providing the wrist pin of a piston with an ununiform-thickness pipe cam consisting of an inner and an outer cams and having a prescribed eccentricity angle, to reduce the descending speed of the piston as to the motion of the crank. CONSTITUTION:An inner cam 2 is secured on the wrist pin 5 of the piston 4 of an internal combustion engine. An outer cam 1 is secured on the small end 7 of  a connecting rod 6. The inner cam 2 is rotatably supported in a position eccentric to the outer cam 1. The eccentricity angle alpha of the inner cam 2 is defined  in such a direction that the connecting rod 6 swings depending on the expansion of the engine. For that reason, the eccentricity angle alpha is set as -thetam/  2<alpha<180-thetam/2 where thetam denotes the maximum swing angle of the connecting  rod 6. As a result, the descending speed of the piston 4 is reduced in relation to  the revolution of the crank 10 to prevent the sharp fall in the pressure on the  top of the piston to give it a higher impulse.

Filed: 1978-06-12
Abstract: PURPOSE: To achieve structural simplification and improvement of handling convenience of a multi-purpose filter by combining constituent substances into one continuous body.  
     CONSTITUTION: A dust-collecting section 5 to be arranged between an electric blower 2 and a charging section 4 is composed of a dielectric filter 7 and granular active carbon 8 applied onto an entire surface of the dielectric filter using adhesive. In this mechanism, when an electric blower 2 is turned, dust-containing air is sucked in through an odor hole 3 and dust particles are charged with electricity at the charging section 4, and then, thus charged dust particles are adsorbed onto the dielectric filter 7, and at the same time, odor, etc., is also adsorbed onto the active carbon particles 8 for cleaning of the air. And therefore, it is possible to achieve capturing of the charged dust and removal of odor or waste gas with a single filter satisfactorily. Further, it is possible to improve dust-collecting (or removing) efficiency by using for the dielectric filter 7 a binder-free dielectric fiber having dielectric constant of 3.0 or more at 10 3  Hz and ozone-proofing performance at waste- absorbing rate of 1.0 or less.
