Filed: 1979-10-03
Abstract: PURPOSE: To make it possible to exactly executing the counting which is free from a counting error, by putting two filaments to one counted object by use of a contactless detector, and making it generate one signal through the latch circuit.  
     CONSTITUTION: When a bottle approaches the photo projector and detector and shuts off a light beam of the photo projecting and detecting part A, the photoelectric switch A6 outputs "1" and B7 outputs "0". Accordingly, the AND circuit 12 outputs "1", and the AND circuit 13 outputs "0". FF14 is set by an output "1" of the circuit 12 and an output "0" of the circuit 13, and outputs "1" to the counter. The bottle moves forward, both the switches A6 and B7 shut off the light beam, the outputs become both "1", and FF14 is not varied but outputs "1". Subsequently, when the switch A6 detects a light beam and B7 shuts if off, the circuit 13 outputs "1" and resets FF14. When the bottle has finished passing in the end, FF14 is not varied even if both the switches A6 and B7 detect a light beam. In this way, the moment only the switch A6 has shut off a light beam, the latch circuit 8 outputs "1" to the counter, and it is returned to "0" when the bottle has passed and only B7 has shut off a light beam. Even if the bottle moves during the said time, the output is not varied erroneously.

Title: Recording and reproducing device consisting of vertically magnetized rigid disk
Inventor: EZAKI JIYOUICHIROU
IPC: G11B5/127
Filed: 1985-06-12
Abstract: PURPOSE:To provide the resolving power that a vertically magnetized rigid disk possesses to the max. extent by relatively moving the vertically magnetized rigid disk and magnetic head apart at the spaced distance unavoidably generated when the disk and head are brought into or tried to be brought into contact with each other. CONSTITUTION:The recording density in the case of the vertically magnetized rigid disk exponential-functionally increases with a decrease in the floating height of the magnetic head. Since the disk and magnetic head are moved relatively with each other, about <=0.03mum spaced distance is generated unavoidably between the magnetic head and the vertically magnetized rigid disk even if the disk and head are tried to be brought into contact with each other. However the spaced distance is of a slight value and therefore the floating height can be regarded substantially h1=0mum, at which the excellent recording and reproducing characteristics as well as recording density characteristic are obtd. The vertically magnetized rigid disk constituted by forming a high magnetic permeability layer 2 on the surface of a rigid base body 1 and forming a vertical anisotropic film 3 on the layer 2 is usable.

Abstract: PURPOSE:To adjust the focusing point with high precision at all times even if a mounted interchangeable lens is different by detecting the quantity of out-of- forcus on a camera main body side, sending information on the quantity of defocusing to the interchangeable lens side, and finding the quantity of driving at the interchangeable lens. CONSTITUTION:A main CPU in the camera main body calculates the quantity of out-of-forcus of the interchangable lens 500 mounted on the camera main body. Then the divergence of forcus quantity data is sent from the data input/ output terminal of the main CPU through an input/output control circuit. This defocusing quantity is inputted to a sub-CPU 501 in the interchangeable lens 500 and the camera enters a stand-by state. Then when a specific signal is sent from the control signal output terminal of the main CPU, a control signal corresponding to the defocusing quantity data is sent from the control output terminal X of the sub-CPU 501 to a driving circuit 511. The driving circuit 511 drives a motor 512 according to the inputted control signal to rotate a focus ring, and thus extends or contracts and stops the lens by a necessary quantity.
