Title: Apparatus for detecting position of pointer
Inventor: HAYAKAWA MOTOMU
IPC: G01D5/12
Filed: 1986-06-11
Abstract: PURPOSE:To enhance the durability of the title apparatus, by detecting the position of a pointer by detecting the load applied to the pointer. CONSTITUTION:A zero position load mechanism 4 is operated by drawing out a crown 3 at the time of the correction of time and a pin protrudes at a zero position (12 o'clock position). At the same time, a rotation detecting pulse is formed by a motor driving circuit 2 and a pointer runs itself until reaches the pin protruding at the zero position. When the pointer reaches the pin and a motor 1 is brought to a non-rotary state, non-rotation is detected by a rotation detecting circuit 5 and motor driving pulses from the point of time when a rotation detecting pulse is formed to the point of time when non-rotation is detected are counted by a counter 6. Further, when the value of the counter is set to (n), the calculation of 60-n is performed by an operation circuit 7 and the calculated value is preset to a pointer position counter 8. Hereupon, the pin at the zero position is drawn back by the mechanism 4 and the value of the counter 8 comes to a pulse by the circuit 2 and the pointer moves corresponding to said pulse. By this method, the position of the pointer is detected and the synchronism with an internal circuit is taken.

IPC: G02B6/40
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To obtain sufficiently handling resistant strength and to obtain excellent workability without exerting excessive stresses on optical fiber ribbons by connecting the optical fiber ribbons drawn out of a cable end to an optical connector in an independent state by having protective sheaths without bundling the optical fiber ribbons to each other. SOLUTION: The optical fiber ribbons 2 drawn out of the cable end have the protective sheaths 3 in the state that the respective ribbons are held independent sheet by sheet without bundling the optical fiber ribbons to each other. The terminal structure of the optical cable with the connector connected to the optical connector 1 is adopted, by which the protective sheaths 3 are respectively independently put on the plural optical fiber ribbons 2 connected to one piece of the connector without bundling the ribbons to each other. Even if, therefore, the optical fiber ribbons are bent, the inner optical fiber ribbons 2 escape freely sideways and, therefore, undue stresses are not generated and the induction of buckling is averted. Further, the fiber ribbons are strong to external damage by handling.

Abstract: PURPOSE: To correct the image distortion generated by the change of the distance to an object, in a device preparing a panorama still image by joining together plural sheets of the reduced images prepared by imaging an object, CONSTITUTION: When the reduction ratio at the center of an object P is defined as 1/Nθ and the reduction ratio at the location of an angle θ is defined as 1/Nθ, 1/Nθ=(1/Nθ)×cosθ×k (k is the constant determining reduction ratio). Thus, because 1/Nθ is decreased when θ is increased, the sizes in the vertical direction on the both sides of the image of the object P are relatively expanded and image distortion is corrected.

Abstract: PURPOSE:To avoid a large size of a step-up transformer and enhance reliability of detection of abnormality by bringing the operation of a magnetron into a halt if a current value detected by an anode current detection circuit of the magnetron is out of a preset allowable range. CONSTITUTION:An output signal of a current averaging circuit 25, which is a signal of an average anode current value Iav of an anode current value Ia detected by an anode current detection circuit is input into not only an error amplifier 26 but also an A/D converter 31, where the output signal is converted into a digital signal to be further input into a microcomputer 32. The microcomputer 32 reads in the signal of the average anode current value Iav according to a control program to determine whether or not the average anode current value Iav is within a range from a present upper limit Imax to a preset lower limit Imin. If the Iav is out of the allowable range, any of component parts of the circuit is operated deficiently. Consequently, a stop signal S5 of a low level is input into an AND gate 2 at the time of detection, and the AND gate 28 is deenergized.
