Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To obtain an accurate and stable PLL clock by conducting PLL with a 1st stage PLL(phase locked loop) circuit at a half of a conventional period and using a rising edge signal of the clock signal so as to lock a 2nd stage PLL. SOLUTION: A 1st stage PLL circuit 38 inputs a rising edge of a reproduction signal to a phase comparator 41 so as to conduct PLL at a half of a conventional period for a preamble area. When the PLL circuit 38 is locked at a half of the conventional period, the clock denoting it is fed to a mask circuit 35, which masks a rising edge signal to generate an edge signal for 2m period only form the leading edge pulse signal. The signal is given to the phase comparator 41 to lock the PLL and a leading edge signal with a half period is given to a phase comparator 46 of a 2nd stage PLL circuit 40.

Title: Automatic amplitude controller of electric oil pressure servo test equipment
Inventor: TAKAHASHI KAZUTO
IPC: G01N3/36
Filed: 1978-11-28
Abstract: PURPOSE: To control the constant amplitude of an electric oil pressure servo vibration test equipment with high precision without reference to an oscillation frequency, by controlling the amplitude of an original signal through an up-down counter by comparing a set value with a feedback signal peak value.  
     CONSTITUTION: An exciter is brought under oil pressure servo-control by a control signal from original signal control source 8. The peak value of a feedback signal from the exciter is detected by peak detector 17 and then compared with a set amplitude value by subtracter 15. In accordance with this comparison result, either AND gate 12 or 13 is opened to apply a clock signal to up-down counter 11 in a period equivalent to the subtraction result, so that counter 11 provided down or up- count. Therefore, the amplitude of the original signal is digitally controlled by analog-digital multiplier 10 according to the count result of counter 11 to perform high-precision electric oil pressure servo-control so that the amplitude of the exciter will be constant without reference to a frequency.

Abstract: PURPOSE:To surely carry out the operation of curving, etc., of an endoscope having a long inserting portion by heating or cooling a metal hydride and feeding/discharging a hydrogen gas to operate a driving device, and operating an operated object via a transmitting member. CONSTITUTION:Since a metal hydride 22 in a curved upper driving device 13a is cooled by a Peltier element 23 to absorb and store a hydrogen gas, air pressure in a casing 14 is reduced to expand bellows 15 as shown by the figure (a) by receiving the negative pressure and the energizing force of a coil spring 18. Hence, a driving rod 17 is drawn in by the amount X to pull an angle wire 12 connected thereto. On the other hand, a metal hydride 22 in a lower driving device 13b is heated by the Peltier element 23 and discharges a hydrogen gas increasing air pressure in a casing 14, to contract bellows 15 as shown by the figure (b) against the energizing force of a coil spring 18. Hence, a driving rod 17 is pushed out by the amount X, to deliver an angle wire 12 connected thereto. Thereby, a curved portion 8 is curved upward.

Title: Plunge cut shaving cutter
Inventor: SUEYASU MASAHARU
IPC: B23F21/28
Filed: 1983-08-10
Abstract: PURPOSE:To minimize each thrust force of a cutting edge in each face against a tooth of a work gear as well as to reduce the thrust force of a cutter as a whole, by altering the arrangement of cutting edges at both acting and counteracting face sides in a proper manner. CONSTITUTION:Cutter teeth Z1, Z6, Z4, Z2 and so on of a plunge cut shaving cutter are installed each in where they should be. A helix A' connecting a cutting edge at the acting face side and another helix A connecting a cutting edge at the counteracting face side are different each other. That is to say, a helix angle of the former is of beta1 while a helix angle of the latter is of beta2. Next, since either cutting edge at both tip side and countertip side cutting edges performs cutting in making a central deepest infeed part of a scarf formed by a preceding cutting edge an infeed starting point, the cutting edge at either side is also minimized in its thrust force to each tooth of a work gear so that the total thrust force of the cutting edge becomes minimized, thus the thrust force of the cutter on the whole is reducible in this way.

Title: Operator's interactive type validation system
Inventor: GOLDMAN ROBERT NORMAN
IPC: G06F21/34
Filed: 1986-06-25
Abstract: Operator-interactive verification of a card-based transaction involves reading a magnetic stripe (24) on the card (C) to derive test data (T) representing an arithmetical combination of a uniqueness characteristic of the card (derived from its translucency at defined locations D1-D6) and the assigned-user's personal-identification data (PIN). The test data (T) is arithmetically-combined with the personal-identification data (PIN) entered by the user, to produce a decoded representation of the uniqueness characteristic (D min ) which is compared with a fresh sensing (D) of that characteristic as a basis for verification of both the card (C) and the user-entered data (PIN). The user can choose to alter his operative personal-identification data (PIN), and does this, after first achieving verification using the exisiting data, by entering the new, chosen data for re-calculation with the decoded uniqueness characteristic (D min ) to produce new test data (T min ) which is then recorded on the card (C) in place of the old (T).
