Title: Zero correcting device for optical measuring instrument
Inventor: SHIRATO KOZO
IPC: G01N21/41
Filed: 1987-05-30
Abstract: PURPOSE:To speedily and accurately perform zero correction by connecting the control circuit of an optical correcting mechanism to a light receiving body electrically and connecting an electric zero correcting circuit to the output side of a light receiving body output amplifying circuit. CONSTITUTION:Light P from a light source lamp 1 passes through a sample cell 2 and is reflected by a reflecting mirror 3 to make it incident on the light receiving body 5 through a glass plate 4. When light P1 is not incident on a sample-side photodetector and a reference-side photodetector element equally, the light receiving body 5 outputs a corresponding signal to the control circuit 6. Then the glass plate 4 is moved by a control motor 8 with said signal so that the light is incident on both photodetectors equally, and thus the optical axis to the light receiving body 5 is moved in parallel to make an optical zero correction. Then the electric zero correcting circuit 7 is connected to the output side of the control circuit 6 to make an electric zero correction. Consequently, the optical correcting mechanism and electric zero correcting circuit operates associatively to make the electric zero correction while maintaining optical balance.

IPC: H04Q9/00
Filed: 1984-07-02
Abstract: PURPOSE:To prevent the operation by the 3rd party for the purpose of mischief and illegal use by counting the frequency of detection of dissidence between calling data and previously stored data which is detected by a collating decision means, and controlling the driving part of a switching means when the counted value attains to a specific value and stopping the operation of a load driving means for a set time. CONSTITUTION:When the operation part of a changeover switch 3 is placed at the absence side, the main device starts operating as a control function to get ready for the incoming of a ring-back tone and when the ring-back tone is detected by an incoming circuit 4, a timer 5 starts to make a relay contact 7 connected to a telephone circuit 6, and the circuit is connected to an extension to send a message of the absence to the calling subscriber from an answer circuit 9. When the operation of said answer circuit 9 is completed, a timer 10 starts and an input decision circuit 11 decides whether or not there is calling data from the originating subscriber within the set time of the timer circuit 10; when not, the relay contact 7 is broken and the wait state is entered.

Title: Device to drive dc motor by step
Inventor: UCHIDA RIYOUHEI
IPC: H02P8/42
Filed: 1980-09-30
Abstract: PURPOSE:To effect control of the driving of a motor and its correct stopping in an open loop without detecting rotational speed, by making the DC motor perform step operation using an integrator. CONSTITUTION:Because the output of an AND gate 12 changes to negative by the change-over of a switch 2 when a time t0 is passed, a constant value current i1 which was flowing in the opposite direction flows in the direction shown in the figure through a capacitor C1, and since a capacitor C2 has a polarity as shown in the figure and the output of a comparator 15 changes from positive to negative, the transistor TR18 is turned on, and because the output of an AND gate 16 stays negative, transistors Q1 and Q3 continue to be on and transistors Q2 and Q4 continue to be off, accelerating a motor 3. When the state of the switch 2 is changed at a time t1, the output of the comparator 15 is maintained positive, changing the  output of the AND gate 16 to positive and turning transistors Q1 and Q3 off and Q2  and Q4 on to invert electric voltage applied to the motor 3, which exerts reverse breaking. At a time t2 the output of the comparator 15 changes from positive to negative to turn off the transistor TR18 and the voltage applied to the motor 3 disappears.

It continuously reads out the first field of the current picture, the second field of the preceding picture, the first field of the current picture, and the second field of the current picture synchronously with the first read sequence in a second read sequence and supplies them to a second signal branch 11. Signals in the second read sequence are used for display of a still picture to reduce the line and edge flicker. The luminance signal in the first read sequence is used for flickerless display of a moving picture.

Abstract: PURPOSE: To reduce the number of components and to facilitate the assemblage by using one spring for press-fixing a tape guide and also integrating a gear and an arm. CONSTITUTION: A torsion spring 21 is interposed between the gear 13 and the arm 14, and the tape guide is moved by the arm 14 and a gear 20 when the gear 13 is rotated counterclockwise, then the tape is drawn out from a tape cassette. When the gear 13 and gear 20 are further rotated, a driving intermittent gear part of the gear 13 is disengaged from an intermittent gear part to be driven of the gear 20. In this state, when the tape guide abuts on a stopper and the gear 13 further rotates by a prescribed angle, a protrusion 13a is separated from the arm 14, and the arm 14 is pressurized through the spring 21. At this time, since a starting arm part 21a of the spring 21 is turned by a prescribed angle by an outside wall of the gear 13, a lever part 20a of the gear 20 is pressurized by the arm part 21a.
