Title: Tripper belt conveyor inversion preventing device
Inventor: TSUKAMOTO MASAKATSU
IPC: B65G47/95
Filed: 1984-03-09
Abstract: PURPOSE:To reduce the surface pressure of a belt when it is suppressed while prevent said belt from being inverted or rocking sideways by providing a belt holding device which moves vertically following the amount of the floating motion of said belt. CONSTITUTION:A belt holding device 1 consists of carrier rollers 11 which are concavely arranged along the form of a belt (a) in the width direction at the time of conveying operation of a belt conveyor, and retainer rollers 12 provided on the upper parts of both edges of the belt (a). A guide frame 2 supports the device 1 vertically slidably, and allows the device 1 to move vertically in accordance with the tensile force of the belt conveyor. As a result, if the tensile force of the belt is unusually varied, the unusual tensile force can be absorbed, without damaging the belt and enabling the belt to always continue normal conveying operation. Accordingly, any inconvenience, such as, dropping an object while being conveyed, etc. can be eliminated, while the life of the belt itself can be sharply increased.

Title: Track access system in optical disk device
Inventor: ARAI SHIGERU
IPC: G11B7/085
Filed: 1983-03-18
Abstract: PURPOSE:To increase a track shift signal level by detecting a tracking signal in a state that a read beam of an optical head is shifted from a focus against an optical disk, in a moving period by an access mechanism, in an optical disk device. CONSTITUTION:An optical head is moved, and a counting value of a track counting part 22 in said moving time, and a tracking information stored in a registor 24, namely, the number of tracks extending form a present position to a target track are compared by a comparator 23. At the time point when both of them coincide, a tracking stop signal is outputted by a VCM stop signal generating part 25, and a movement of the optical head is stopped. At this time point, an offset setting part 16 is reset so as to set a lens of the optical head to a focused state. At this position, an address signal of a sector address part is read out, and basing on it, the number of track errors to the target track is calculated. By a dense access mechanism, the lens of the optical head can be corrected and displaced to a prescribed track position.

Title: Fitting structure for armrest bracket
Inventor: YAMAUCHI YOSHIHIKO
IPC: B60N2/75
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent over-enhancing of the rigidity of a seat back while ensuring the necessary fitting strength of an armrest bracket. SOLUTION: Since only the upside fitting part 15 of the armrest bracket 7 is fitted through a holding member 22 of a low strength, the rigidity of the seat back is not too mush enhanced. Namely, when a backward load is applied to the seat back, a shoulder bolt breaks (or deforms) the holding member 22 and is pulled out backward from the notched upside fitting part 15, thereby allowing the seat back to be deflected backward to surely absorb the backward load.

Title: Push-pull amplifying circuit
Inventor: SAKAI KAZUMASA
IPC: H03F3/30
Filed: 1979-04-16
Abstract: PURPOSE:To prevent switching distortion from being generated, by providing a current path for bias between the base of the output transistor of a push-pull PP amplifier, which is constituted by symmetrical circuits, and the earth or the power source. CONSTITUTION:In symmetrical PP amplifying circuit of inverted Darlington connection, resistances 17 and 18 are provided between the base of output transistors 1 and 2 and the earth, and resistances 7 and 8 are provided between the base and the power source. The bias circuit is adjusted for the class B amplification and is so adjusted that a proper DC bias current may be flowed to Tr1, 2 when no input signal exist. In case of a positive input signal voltage, a current is supplied to load  11 from Tr3 and Tr1. At this time, driving Tr4 is cut off, however, the bias current is flowed to Tr2 by resistances 7 and 17 to prevent Tr2 from being a cutoff  state. Similarly, in case of a negative input signal, Tr3 is cut off, however, Tr1 is  not cut off due to resistances 8 and 18. Consequently, this circuit functions as a PP  amplifier of the class AB, and switching distortion can be prevented, so that the  distortion rate can be lowered.

Title: Internal combustion engine with intake pipe consisting of plastic at least partially
Inventor: BUECHL JOSEF
IPC: F02D11/10
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent a voltage flashover from being formed by guiding a charge generated in an intake pipe area to the connection part of an electric motor through a sufficiently conductive connection part. SOLUTION: Two resistances 28 and 32 installed in electric connection parts 26 and 30 between a throttle fitting pipe 12 and electric motor connection parts 20 and 22 are designed so that an exciting current for an electric motor 18 is not shortcircuited. Accordingly, the resistances 28 and 32 are designed to have high resistances. A charge generated in an intake pipe area can be led to an electric motor connection parts 20 and 22 through electric connections 26 and 30 and, therefore, can flow out at a low ohm through a final stage. Particularly advantageous points in this case are that a spark eliminating system is provided in an electric motor 18 - driving control device 24 at the last stage, an inductive voltage peak of the electric motor is eliminated, and also a static electricity voltage peak is eliminated effectively.  Thus, a static charge can be induced effectively by a minimum cost with respect to a wiring technology.

Title: Emphasis device with clip function
Inventor: NISHINO SHOICHI
IPC: H04N5/93
Filed: 1985-03-08
Abstract: PURPOSE:To shorten a time converging to a signal level of an original signal and to reduce a distortion in a waveform by passing a clipped signal through a high pass filter HPF constituting a part of a deemphasis of a reverse characteristic of an emphasis characteristic and feeding back to an input signal. CONSTITUTION:From an input terminal 13, a step signal of Fig. (a) is inputted. At this time, a signal outputted from an output terminal 24 is limited in its amplitude by a clip level V to be as shown in Fig. (f). Herein, a period from a time t0 to a time t2 is a period that an output signal (f) is clipped by the clip level A and after the time t2, by non-clipped emphasis characteristic, the output is converged to a signal level of a signal (a). When the signal (f) is inputted to a deemphasis device, the output becomes like a signal (i). This signal (i) reaches a signal level U of the original signal (a) at the time t2. After the time t2, the signal (f) of the input signal is converged to the signal level U by a time constant of an emphasis characteristic, so that the signal (i) responds holding the signal level U.
