Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To continuously and automatically inspect and determined the state of the full outer periphery of a cylindrical work on a line by providing an optical inspecting means for inspecting the full outer peripheral surface of the work while the work is rolled on the outer peripheral surface of a rotary body. SOLUTION: When a rotary roller 1 is rotated by a specified rotational angle and a work W reaches a work inspecting position, the system of a video section starts its operation, and the inputting of a video signal output is started from an image sensor 7 according to the state of the outer peripheral surface of the cylindrical part of the work W. Further, a work rotational speed detecting means starts detecting the rotational state of the work W. When the rotary roller is rotated and moved by a next specified rotational angle, the change of a video signal output equivalent to one rotation of the work thus far is compared with a specified slice level as a good product level, and defectiveness determination is executed. Thus, if a defective product is determined, a pneumatic control valve 13 is actuated, a pneumatic cylinder 12 is tension-operated, and a down plate 5b is opened.

Title: Photographic lens driving device of camera
Inventor: TAKAHASHI YOSHINOBU
IPC: G02B7/08
Filed: 1990-03-05
Abstract: PURPOSE:To eliminate the out of focus of a photograph by positioning a photographic lens at a specific focus position not while a changeover switch is being operated, but by releasing. CONSTITUTION:When the changeover switch 4 is operated at the time of the movement of the photographic lens from the wide-angle position to the telephoto position, a motor 12 operates to move a moving lens barrel forward and when one end of a position detection main contact Ed nearby the telephoto position is detected, the motor 12 stops to hold the lens barrel at the position concerned. Then when a photographer determines composition and operates a release button, the motor 12 operates again to move the moving photographic lens barrel to the other end of the position detection main contact Ed for telephotography position and the shutter is released to complete photography. Therefore, even if the moving lens barrel is touched by the hand carelessly during the determination of the composition to shift in position, the lens barrel is at the telephoto position in the shutter releasing without fail, so no defocused photograph is taken. Consequently, out of focus is precluded.

Title: Adjusting method for spraying rate of harmful gas absorbent solution
Inventor: HAYATSU MASAKI
IPC: B01D53/81
Filed: 1980-04-21
Abstract: PURPOSE: To spray the absorbent solution at a rate corresponding to variation of the harmful gas  concentration, and to facilitate the maintenance of the apparatus, by adjusting the spraying rate  of the absorbent solution on the basis of the temperature difference of the waste gas between the  inlet and outlet of the absorption column and the concentration of harmful gas contained in the  processed gas.  
     CONSTITUTION: If the spraying rate of absorbent solution is excessive, the temperature difference  ΔT=T 1 -T 0 , between gas temperatures at the neighborhood of inlet 12 and outlet 18 of the absorption column, has relation to the absorption efficiency. The harmful gas concentration W i  at  the inlet of absorption column is calculated from the absorption efficiency calculated from the  temperature difference ΔT, and the harmful gas concentration W o  at the neighborhood of outlet  of the absorption column. From this value W i , the optimum spraying rate of absorbent solution is  calculated and the control valve 30 is adjusted. If the spraying rate of absorbent solution is less  than the saturable amount, the inlet harmful gas concentration W i  is calculated from the outlet  harmful gas concentration W o  and the harmful gas concentration W to be absorbed in the absorption column which is to be obtained from the amount of influent waste gas Q and the spraying  rate F of absorbent solution; after that, the valve 30 is adjusted similarly.

Title: Automatic level controlling circuit
Inventor: SHINODA HATSUHIKO
IPC: H03G3/20
Filed: 1981-04-09
Abstract: PURPOSE:To prevent the breakage of a tweeter of a speaker system when a high-level signal is supplied, by controlling a gain controlling circuit with the output signal of a detecting circuit that detects the working state of an electric power amplifying circuit. CONSTITUTION:The level is increased for the aural signal which is supplied to an input terminal, and an electric power amplifying circuit 4 works in a saturated region. Thus the output of the circuit 4 is clipped at its peak part. In this case, the negative feedback quantity which is supplied to a voltage amplifying circuit 3 is reduced to less than the level of an input signal via a negative feedback circuit 6. As a result, the output signal of the circuit 3 increases suddenly to be supplied to a working state detecting circuit 7 in the circuit 4. Thus a control signal is obtained at the output side of the circuit 7. This control signal controls an FET2b which forms a gain control circuit 2, and as a result, the level of the signal to be supplied to the circuit 3 is reduced. Thus the circuit 4 becomes active in a linear region to prevent the continuous supply of the electric power higher than the allowable level to a tweeter of a speaker system. Thus the breakage of the tweeter can be avoided.
