Title: Input device
Inventor: HENMI KAZUHIRO
IPC: G06F3/038
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To improve operability, also to miniaturize a device itself and to improve the mobility of an information terminal by detecting the moving direction and the moving amount of a skin part on an electrode array from the change of an electric characteristic value between electrodes of an electrode array. SOLUTION: An analog switch is controlled and the same lines of an electrode array 1 are connected when personal identification is requested. A finger 4 that should perform signal detection is pressed along an orthogonal direction to the arrangement direction of the same line electrodes. In such cases, resistance values of a finger 4 surface between adjacent electrodes are sequentially read by switching the analog switch in a longitudinal direction of the finger 4. When the finger 4 is brought into contact with n pieces of electrodes, the resistance value between electrodes changes in accordance with the contact area of the finger 4 that comes into contact between adjacent contact electrodes.  For instance, potential difference of both ends of reference resistance has a large value at a place where the contact area of the finger 4 and electrodes is wide, and potential difference has the smaller value as the contact area becomes the narrower. Then, it is possible to identify the person himself and other persons by comparing these potential differences.

Filed: 1988-02-26
Abstract: PURPOSE:To prevent strain of an electron beam diffracted image and to simplify the constitution of the title device by reversing the turning direction of current allowed to flow through the filaments arranged in a crucible in one part for the other part. CONSTITUTION:The crucibles 4, 5 are arranged in a vacuum chamber 1 and the filaments 16, 17 are fitted to the outsides thereof respectively.

Title: Moving coil type device
Inventor: FUJIMOTO MASUO
IPC: G01R5/02
Filed: 1979-04-12
Abstract: PURPOSE: To improve the deflection angle characteristics with respect to the input current and thereby to improve the current sensitivity of the coil, and at the same time, to make the device compact and light by providing a notch on a magnet placed in the magnetic field inside a moving coil type device and thereby forming a closed magnetic circuit.  
     CONSTITUTION: Notch 33 with a depressed cross section is cut on surface 5a of magnet 5 opposite a coil 4 inside the magnetic field. When the depth of this notch 33 is magnetized into an N pole, for example, stepped parts 5b, 5c become N poles of the same polarity. As a result, a magnetic field of the direction opposite to the direction along surface 5a, that is, a counter magnetic field, is set up, and the magnetic field moving from the N poles in the direction perpendicular to the surface of the coil 4 is weakened by this counter magnetic field. By this, the relationship between the rotational angle of the coil 4 and the average magnetic flux density operating on the coil 4 is made uniform. Consequently it is possible to improve the linear characteristics of the rotational angle of the coil 4 with respect to the input current over a wide range, and compared with the lateral width W of the device, the range of the width of coil deflection can be taken wide, so that it  is possible to make the device compact and light.

Title: Control device for roll eccentricity

Filed: 1985-03-08
Abstract: PURPOSE:To improve the quality of product by providing the units, used for computing the change of unit tension of a stock to be rolled and the propagation delay of tension thereof, and controlling the unit tension in consideration of the propagation delay of tension. CONSTITUTION:A detecting unit 101 of a disturbance of roll eccentricity and a phase detecting unit 102 thereof, are provided. An arithmetic unit 107 computes the timing and amount of roll-eccentricity control based on the signals of units 101, 102, to command a rolling reduction device 103. At that time, the amount of disturbance of roll eccentricity and its phase signal are stored in a tension- control command unit 108, to form the same model of roll-eccentricity disturbance as the roll eccentricity control. The units 101, 102 transmit necessary data to respective arithmetic units of a tension influence factor and a tension propagation delay, to control the tension by the unit 108. In this way, the tension is properly controlled by estimating the tension variation due to the variation of draft position.
