Title: Control method for sheet conveying device
IPC: B65H5/06
Filed: 1992-03-26
Abstract: PURPOSE:To smoothly stop and restart driving of a stepping motor without hindering sheet conveying performance and to prevent sagging of the sheet between each roller pair. CONSTITUTION:After a sheet which has been conveyed by a roller pair 32 driven by a stepping motor is started to be conveyed by a roller pair 33 positioned downstream of the roller pair 32, feeding of an electric current to the stepping motor is cut off to bring the roller pair 32 into a following rotation state. When a next sheet is to be conveyed by means of restart of the roller pair 32 while the roller pair 32 is in the following rotation state, current for rotation to immediately cope with a predetermined conveying speed is fed to the stepping motor. Further, in the case where a succeeding sheet is to be conveyed at a small interval, a current for rotation to immediately cope with a predetermined conveying speed is fed to the stepping motor after a lapse of a specified time after the roller pair 32 is brought into the following rotation state.

Abstract: PURPOSE: To make possible high-performance-and high-frequency-vibration by providing a separate control loop within a closed loop which controls an exciting table and controlling horizontal, vertical and rotation excitations without interference.  
     CONSTITUTION: Horizontal vibration of a vibrating table 1 is controlled by the closed loop control formed by a horizontal system controller 17, horizontal exciting power generating mechanism 13, vibrating table 1, compensating circuit 16, etc. In this closed loop a horizontal rotation separate control means 6 forms a loop. The means 6 makes addition and subtraction according to the inputs of the controller 17 and rotation system controller 21 and adds the correction control signal responding to the horizontal control deviation by the rotation system to the horizontal excitation control loop. The same holds true of the vertical system and rotation system, wherein the horizontal, vertical and rotation systems are separately controlled without mutual interferences by the separate control means. Hence, vibrations are generated with good response to the command signals of high frequencies and the high- performance-and high-frequency-vibrations are generated in the vibrating table.

Title: Measuring method of peak shifting quantity of magnetic disk device
Inventor: YANAGI MASAHIRO
IPC: G01R29/02
Filed: 1984-04-06
Abstract: PURPOSE:To measure accurately a peak shifting quantity with high precision by separating and simplifying recording data and measuring them individually. CONSTITUTION:The error output of a phase comparator 1 is the quantity of the shift of reproduced data from a reference clock VFO, i.e. a peak shift including jitters of every bit, and plus and minus polarities are outputted. Both polarities are ORed and absolute value data is inputted to a counter circuit 23. A microcomputer system 105 controls a counter 103 according to a program mode to sample and store about 3,000 data on one track in a memory. When data processing is carried out in the system 105, all of every 1,500 data corresponding to a half track are summed up and divided by the number of all data to calculate the mean value. Therefore, the peak shifting quantity when data are measured at intervals of a half track is calculated and a larger value is regarded as the final peak shift quantity.

Abstract: PURPOSE:To perform main light emission securely even when the charge of the 1st capacitor is all consumed in preliminary light emission by providing a light emission maintaining circuit which supplied the charge of a flashbulb for a specific time during the main light emission. CONSTITUTION:If the charge of the capacitor 6 is all discharged in the preliminary light emission, a one-shot circuit 35 sends out a pulse with a synchronizing switch on and the charge of the capacitor 6 is consumed even when a trigger circuit 32 is triggered. For the purpose, flash light emission is ceased, but this is prevented by the light emission maintaining circuit composed of a resistance 82 and a capacitor 83. Namely, the capacity of a capacitor 83 is small as compared with that of the capacitor 6 and the capacitor 83 is charged instantaneously after the preliminary light emission.

Abstract: PROBLEM TO BE SOLVED: To provide an optical wave-guide manufactured inexpensively and easily. SOLUTION: A Fresnel lens structure part 22 is formed in a prescribed position of an upper face 14A of a light-guide medium 14, and an optical wave-guide 10 is constituted by the structure part 22 and a lower face 14B of the medium 14 of its opposed face.
