Patent JP-H01191512-A (JP)
Title: Latch circuit
Inventor: NASU HIROAKI
IPC: H03K17/22
Filed: 1988-01-27
Abstract: PURPOSE:To simplify the circuit constitution and to decrease umber of components by providing the 1st switch circuit interrupting a path to a power supply in response to a preset signal and the 2nd switch circuit setting the preset state and not providing a switch circuit to hold the state. CONSTITUTION:When a reset signal inverse of R goes to 'L' with a clock pulse C at 'H' level and inverse of C at 'L' level, the potential at a point A goes to 'H' level, an 'L' level is outputted at an output of an inverter 7 to cause the reset state. With the rest signal inverse of R at 'H' level, a P- channel MOS transistor(TR) 3 is turned off, an n-channel MOB TR 6 is turned on and the circuit comprising MOS TRs 1-6 acts like a clocked inverter. Thus, with the clock pulse C at 'H' level and inverse of C at 'L' level, the level is maintained for a time decided by the leakage characteristic of the parasitic capacitance at the point A and the leakage characteristic of the MOS TRs 1-6. Thus, it is possible to omit the clocked inverter for feedback.

Title: Device for tuning photographing lens of autofocusing camera
Inventor: MATSUDA MOTONOBU
IPC: G03B13/32
Filed: 1984-01-30
Abstract: PURPOSE:To simplify constitution by passing constant current to the capacity component of a piezoelectric element for the time corresponding to a distance signal to charge said element and deflecting the piezoelectric element according to the charging voltage. CONSTITUTION:When the operator directs a camera to a desired object and pushes a shutter release button, a switch 42 is closed and the distance up to the object is detected by a distance measuring instrument 34. The terminal T1 of a system control circuit 44 falls further to a low level and the terminal T2 rises to a high level by which a transistor Tr20 is made non-conducting and Tr28 conducting. On the other hand, the terminal T1 falls to the low level and therefore Tr30 is made non-conducting and constant current is impressed to a piezoelectric element 16 by which the voltage of the capacity component thereof is gradually increased. When the value of a counter 36 coincides with the binary signal from a decoder 32, the terminal T3 rises to a high level by which the Tr20 is made conducting and Tr28 non-conducting and the impression of the constant current to the element 16 is interrupted. The voltage meeting the distance signal is thus charged into the component 16a. The element 16 deflects according to said voltage and the state thereof is maintained.

Filed: 1983-02-03
Abstract: PURPOSE:To obtain an optimum reproduction state by detecting the minimum envelope of a head output on every turn of a sheet while shifting a head position in the breadthwise direction of a track, finding the reproducing head position having the maximum value to set the head position basing on the value. CONSTITUTION:An envelope signal 21 is inputted to a minimum holding circuit 23 to obtain the 1st hold output 24. The 1st hold output right before the 3rd rotation pulse signal 34 rise holds the minimum value of the envelope signal 21 of a reproduced signal 16 from the falling of the signal 34 preceding one turn. The pulse width of the 2nd and the 3rd rotation pulse signals 32 and 34 are set much shorter than the period of one turn, so the circuit 23 detects the minimum value of the envelope signal 21 on every turn. The 3rd latch output 56 is held at a level ''H'' when the output value of the 2nd voltage buffer 36 at the output timing of the 2nd rotation pulse signal 32 increases or at a level ''L'' when it decreases.

Title: Manufacture of vibrator
Inventor: OOHASHI YOSHIAKI
IPC: F04B43/04
Filed: 1984-01-30
Abstract: PURPOSE:To maintain the constant amplitude without correction of an applied voltage to a vibrator by applying a d.c. voltage by which a piezoelectric ceramic thin plate shows an extending direction or a shortening direction to this plate when sticking the plate and a metallic thin film together. CONSTITUTION:The disc-shaped piezoelectric ceramic thin plate 2 is stuck to the disc-shaped metallic thin plate 5 under the condition that the voltage by which said piezoelectric thin plate 2 shows an extending direction is applied to this plate 2. Namely, the flat thin plates 2 and 5 both of which do not bend under the condition that a d.c. is applied with the thin plate 2 side as a negative pole are stuck together by use of an adhesive to fabricate an unimorph vibrator 1. After completing the sticking, the vibrator 1 bends as shown in the drawing when application of a voltage stops. Thus, an internal stress is applied to the plate 2 is inverse direction to the variation in a low-temperature region in advance. Consequently, the thin plate 5 shrinks more than the thin plate 2 according to the variation of temperature toward the low-temperature region and the internal stress is alleviated and the amplitude is enlarged. Then the reduction of discharge quantity due to enhancement of viscosity in the low-temperature region can be compensated.

Abstract: PURPOSE: To disconnect a station with its photo coupler in trouble from a transmission line by equipping a slave station, which transmits and receives data to and from a master station via the same transmission line by using a photo coupler, with a method of detecting an abnormal photo coupler.  
     CONSTITUTION: When the luminous element of photo coupler 5 of slave station 2 shots, data are considered to be received even in a short state since data transmission is negative logic, and timer 10 starts operating via inverter 9.

Consequently,  the system can be operated without influencing the data transmission between the  master station and any other slave station and the reliability of the data transmission can be improved.
