Title: Carrier reproduction circuit
Inventor: YAMADA IZUMI
IPC: H04N5/455
Filed: 1993-03-24
Abstract: PURPOSE:To provide the carrier reproduction circuit tracked automatically to a frequency deviation even when a large frequency deviation is in existence in an IF carrier. CONSTITUTION:A limiter amplifier 2 extracts only a carrier component from an IF carrier. A phase comparator 3 of a PLL compares the carrier component with a reproduced carrier obtained by multiplying a signal generated from an oscillator 22 having a ceramic vibrator 10 and varactor diodes 13, 14. When the result of comparison indicates noncoincidence, an output from a comparator 16 is inverted to activate a low frequency oscillator 17, and an output from the oscillator 17 activates an up-counter 18. A D/A converter 19 provides a current output in response to an output of the up-counter 18 and the current is converted into a sawtooth wave voltage at an inverting amplifier 20 and the voltage is applied to the varactor diodes 13, 14 being components of the oscillator 22, in which the capacitance of the diodes 13, 14 is changed to cause a change in the oscillated frequency.

Title: Logic circuit
Inventor: HIRANO YOUJI
IPC: H03K19/084
Filed: 1978-05-30
Abstract: PURPOSE:To obtain the logic circuit of excellent interruption characteristics, by providing the diode in which the anode is connected to the base of Tr and the cathode is to the input terminal, with the logic circut consisting of transistor Tr the conduction of which is controlled depending on the logic input. CONSTITUTION:The circuit consists of the schottky clamped Tr Q1 to Q4, Q6 and TrQ5, and schottky barrier diodes D1 to D6. TrQ1 is ON and Q2,Q3 are OFF when low level is fed to either of the terminals 3 and 4, to maintain Q4 and Q5 OFF. When high level is fed to the terminals 3 and 4, TrQ1 is OFF and Q2 is ON, the collector potential decreases to keep Q4,Q5 OFF and Q3 ON. With this state, if the terminal 3 is changed to lower level, since Q1 is ON and Q2 is OFF, the base charge of Q3 is discharged via the resistor R5 and Q3 starts disconduction. D3 is changed from the back bias to the forward bias, the base charge of Q3 is rapidly discharged through D3 to improve the interrupting performance of Q3. Thus, the conductive performance is not injured and excellent interruption characteristics can be obtained.

     CONSTITUTION: When an English word, e.g., asked, is fed to a register 1, the address is renewed until the output of a memory unit 2 is the same as the content of the register 1 with a retrieval instruction signal 7 and a coincidence signal 8 is output when in agreement. The signal 8 drives a synthesizer 10 and the rule of the past form output from the index word output of the memory unit 2 and from a memory unit 5 forms the conjugation added to the tail of word for the detection of coincidence with the word stored in the register 1. Thus, words other than basic form can efficiently be retrieved.

Filed: 1987-03-23
Abstract: PURPOSE:To obtain the same target tracking error performance as that at the time of actual target tracking by obtaining a target tracking error signal necessary for dummy target tracking from the output signal of an angle comparator. CONSTITUTION:The angle comparator 8 inputs a target direction from a dummy target generator 6 and the direction input of an image pickup device 1 from a driving device 5 to compare the angles and outputs an angle error signal. A tracking error switch 10 disconnects the output of an image processor 3 at the time of dummy target tracking and inputs the angle error signal of the comparator 8 to a servo-amplifier 4. Therefore, the target error signal required for the dummy target tracking of the amplifier 4 is obtained not be performing the image processing of a video signal generated by a dummy image generator 7, but by the comparator 8 from the output of the device 6 and the output of the device 5, and the waste time of the device 7 does not appear as a tracking error. Thus, the same performance as the tracking error performance at the time of the actual target tracking is obtained at the time of the dummy target tracking.

Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of the spacing between the tips of stator teeth and a permanent magnet rotor and further control vibration in the stator by providing a coupling ring with engaging portions which secure a first outer magnetic pole and a second outer magnetic pole in the direction of the diameter and engage them together. SOLUTION: In the case of a second stator 19, an outer magnetic pole 19b is engaged with engaging portions 10g and 10h formed in a coupling ring 10, and an outer magnetic pole 19a is engaged with engaging portions 10i and 10j formed in the coupling ring 10. The tooth sides 19h and 19i of the outer magnetic pole 19b in comb shape divided in the direction of the circumference of the outer magnetic pole are formed by a plane that crosses the cylinder core and are increased in tooth width as they go toward the circumference. The grooves to be engaged with the outer magnetic poles, formed in the coupling ring are so formed that they are slightly smaller than the width of the teeth and thereby the movement of the outer magnetic poles is forcedly limited.  Thus the vibration in the outer magnetic poles is suppressed and the spacing between the outer magnetic poles and a permanent magnet rotor is kept constant. As a result, vibration in the motor itself due to magnetic eccentricity is suppressed.
