Title: Form detector
Inventor: KOMATSU TADANORI
IPC: G01B11/24
Filed: 1979-05-23
Abstract: PURPOSE: To automate the detection of the form of an object and to improve the S/N ratio, by applying light diagonally from two light sources disposed in different places to the same portion of a projected object, and determining the form of the projected object on the basis of a shadow signal obtained through a light receiver, a memory, a subtracter, and an operator.  
     CONSTITUTION: A printed board 10 provided with electric circuit parts 11 is placed on a block with legs 13 of the parts 11 upwardly directed, and the legs 13 are irradiated with illuminators 14, 15 in order. When the legs 13 are irradiated with the illuminator 14, image signals representative of shadows 23a of the legs 13 and board patterns 24W27 are memorized in the image signal memory 19 through the light receiver 16 and an interface 18. When the legs 13 are irradiated with the illuminator 15, image signals representative of shadows 23b and the board patterns 24W27 are also memorized in the memory 19. The signals representative of the board patterns 24W27 are then eliminated by the subtractor 20. The signals representative of the forms of the legs 13 are compared with a set value in the operator 21 to output a judgement signal to a judging unit 22. Thus, the mounting condition of a smaple can be detected automatically at the high S/N ratio.

Title: Recorder
Inventor: NAKAGAWA YOSHIHIRO
IPC: B41J35/36
Filed: 1985-03-26
Abstract: PURPOSE:To contrive a reduction in power consumption, by providing a means for stopping the driving of a ribbon end detecting means when a carriage is located at a specified position. CONSTITUTION:A reflection-type photosensor 5 as a ribbon end sensor and a microswitch 6 as a carriage position sensor are mounted on the carriage, and a stopper 7 is so provided that when the carriage 1 is moved to a home position, a switch 6 is turned ON to indicate the home position of the carriage. When the carriage 1 is located at the home position, the microswitch 6 is turned OFF, resulting in that no electric current is passed from a power source 9 to a LED 5-1, and a controller for a printer does not detect the ribbon end. On the other hand, when the carriage is moved from the home position for printing, the switch 6 is turned ON, whereby a current is passed to the LED 5-1, so that when the ribbon end comes to the position, a reflective member provided on the ribbon is detected, and discrimination can be performed. Accordingly, in the case of stand-by of the carriage 1 at the home position or in similar occasions, the LED 5-1 is turned OFF, so that the wasting of electric power can be prevented.

Title: Color video reproducing device
Inventor: KITAHARA NOBUHIKO
IPC: H04N9/79
Filed: 1988-03-16
Abstract: PURPOSE:To continue reproduction even in case of the drop-out of an identification signal by generating a forecast identification signal whose detection before detection of the identification signal is forecasted and generating a memory control signal for separation based on this forecast identification signal. CONSTITUTION:When a vertical synchronizing signal is detected by a vertical synchronizing signal detecting circuit 18a, a memory control signal generating circuit 18c executes switching of the memory control signal. The identification signal is inputted to the circuit 18c, and this circuit 18c forecasts the next identification signal to generate the forecast identification signal. This forecast identification signal is used for switching of the memory control signal. If detection of the identification signal is omitted, the forecast identification signal is generated based on the past identification signal. Since the identification signal has the periodicity of R, G and V, plural identification signals are easily obtained. Though the identification signal is dropped out or a false identification signal is generated, R, G and B signals are accurately separated by this constitution.

Title: Fly-back voltage absorbing circuit of exciting coil
Inventor: NAITOU YOSHIHIRO
IPC: H01J49/20
Filed: 1984-03-29
Abstract: PURPOSE:To shorten the scanning time of a magnetic field without destroying a driving transistor (TR) by driving corresponding photodiodes with outputs of respective voltage comparators and putting a voltage limiting circuit in operation, and preventing an overvoltage from being applied to a TR for current control. CONSTITUTION:When a triangular-wave coil driving signal is supplied to the base of the TR1 for current control, the TR1 operates and the current flowing through the exciting coil L1 decreases gradually. The exciting coil current I is scanned from O(A) to I2(A) from time O to time t1. When the exciting coil current returns to I2(A) at time t1, a fly-back voltage is developed across the exciting coil L1. At this time, the fly-back voltage is limited by the current limiting circuit to less than a specific value, so the base-collector voltage VBC of the TR1 for current control is also limited to less than the specific value, so the TR is protected from destruction.

Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To eliminate influence exerted on the installation example of a space station and a satellite and the like by canceling inertial force at the time of actuating a telescope concerning the telescope. SOLUTION: The main body 1 of this telescope in which a reflection mirror, a condenser and a camera or an ocular are housed is supported on a base part 4 turnably around an X-axis by a shaft 3 through main body supporting parts 2a and 2b. The main body 1 also turns around a Y-axis. When the main body 1 is rotated in the direction α1 around the X-axis, counter weights 6a and 6b are driven by a rotating body driving part 10 and rotated in the reverse direction α2 so as to negative the generated inertial force. When the main body 1 is rotated in a direction β1 around the Y-axis, the counter weights 8a and 8b are rotated in a reverse direction β2 so as to cancel the generated inertial force. The telescope therefore can be used in the space station.
