Abstract: PURPOSE:To provide a fine line diameter measuring device capable of measuring fine line diameter in high precision. CONSTITUTION:When a distance from an intersection C between a laser beam B and a line sensor 3 is made (x), light intensity I (x) of a Fraunhofer's diffracted image, is multiplied by a value of k.x<2> ((k) is proportional constant) by means of a multiplying circuit 7, thereafter, it is differentiated by a differentiating circuit 8 and a zero point of a signal D after this differentiation is detected by a zero point detection circuit 9. A computer 12 computes the line diameter phi of a fine line W to be measured in accordance with an interval between the zero points and it is indicated on an indicator 13. It is possible to measure a fine line diameter in high precision.

Title: Mobile communication method and mobile communication system
Inventor: NOZATO MASAYA
IPC: H04L9/16
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a mobile communication system where the start of communication between a mobile station and a stationary station is quickened and a key in use is quickly and securely switched against an illegal use of an encryption key or the like. SOLUTION: Common keys with plural versions are available for encryption communication between a stationary station and plural mobile stations, each mobile station 1 manages a sole key version and its symmetrical key (ordinary key and emergency key) in a form of key information DB 6, and the stationary station 2 manages plural key versions and their symmetrical keys in a way of key information management DB 12. The mobile station 1 sends a key version of its own station on a communication request, the stationary station 2 discriminates whether or nor a usual key of the received key version is effectively supported and replies the version and the key application (normal), when it is effectively supported. When the usual key is invalid, the stationary station 2 replies the version and the key application (urgent).  The mobile station 1 discriminates the key version and the key application replied from the stationary station 2 and switches the key used by its own station into the urgent key, even if the key version is the same when the key application is the 'urgent key'.

Abstract: PURPOSE:To reduce the scale of a circuit, by controlling the emission current from a linear cathode and a beam current flowing in a vertical focusing electrode so as to keep always the difference between them a fixed value. CONSTITUTION:In order to make the difference between an emission current and an electric current flowing in a vertical focusing electrode 3 a fixed value, only one set of circuit is used to detect the oscillating component of each linear cathode 2. By fetching the mean voltage 98 of all emission times except the blanking period from a DC component detecting circuit 92, comparing the mean voltage 98 with the output of a differential component detecting circuit 91 at an oscillation/luminance difference detecting circuit 93, and supplying the compared output to a feedback drive circuit 49, an output 100 to be supplied to a back electrode 1 is obtained. When the feedback is opened, the output is made to the limit and, when the feedback is closed, the differential voltage becomes almost flat because correction is made.

Abstract: PURPOSE:To obtain a circuit latching a stable level shift with respect to a temperature by providing a constant voltage generating circuit and a source follower circuit. CONSTITUTION:A Schottky gate field effect transistor(TR) (MESFET) 12 acts like a constant current source with a constant voltage from a constant voltage generating circuit 18 when the temperature is constant, a gate-source voltage (Vgs) of the MESFET 11 is always made constant and the input signal given to an input terminal 13 is subject to level shift at all times by a prescribed amount and the resulting signal is outputted to an output terminal 14. When the temperature rises, a voltage from the constant voltage generating circuit 18 given to the gate of the MESFET 12 rises. Thus, the current supplied by the MESFET 12 is increased, resulting that the Vgs of the MESFET 11 is kept constant, then the stable level shift against temperature is kept.
