Title: Cathode structure and its manufacture
Inventor: NIKAIDO MASARU
IPC: H01J29/04
Filed: 1984-11-09
Abstract: PURPOSE:To reduce amount of heat distortion under operation by forming a support of invar alloy, by melting-metal-quenching method, in order to fix base metal and electron radiation material on a negative electrode sleeve, and to suspend the sleeve from a negative electrode support cylinder. CONSTITUTION:A cathode structure of quick-motion type used in a Braun tube or the like is formed by fixing a base metal 2 which prepares electron radiation material 1 on the upper part of a sleeve 3 housing a heater 10, and by welding one end of a ribbon-shaped support 4 and the other end respectively to the lowermost part of the sleeve 3 and a negative electrode support cylinder 5, in the posture in which the sleeve is suspended. Together with making the support 4 with invar alloy such as Fe-Ni or stainless steel, it is formed by melting-metal-quenching method, in which melting metal is supplied from a nozzle to the surface of a cooling roll rotating at high speed and then solidified. Hence the support having less heat distortion, without nearly recrystallized and grain-grown, can be obtained, with fluctuation of cut-off voltage being decreased.

Title: Tracking apparatus for target
Inventor: FUJINAMI KIYOHISA
IPC: G01S13/66
Filed: 1990-09-05
Abstract: PURPOSE:To improve the capacity of tracking a target, by providing an operator information input processor and a target track inference device and by applying a fuzzy inference to calculation of a threshold level which serves as the criterion of determination of the stop of target tracking. CONSTITUTION:When it is assumed that a target 15 of tracking is caught by an antenna beam 14 at some time point, first, the detected data thereon are received by an electronic scanning antenna 2 and inputted to a target tracking device through a transmitter-receiver, an intermediate signal processor, a target duplexity determinator, a target discriminator and a detected data selector. The target tracking device computes the reliability of the detected data from a difference between the detected data and the current position of the target computed beforehand, and the reliability thus computed is inputted to a target track inference device. The target track inference device computes the reliability of the assumption that 'the target is present in a track being traced currently', from the reliability of the detected data. Next, a threshold level is computed on the basis of fuzzy information from an operator information input processor. When the reliability of the assumption turns to be below the threshold, it is judged that 'the target is not present in the track being traced currently', and a signal for stopping tracking is outputted.

Title: Motor-driven zoom camera
Inventor: IKEDA TAKAHIRO
IPC: H02P7/06
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts used in a zoom camera and, at the same time, to reduce loss in the camera, by constituting a drive control mechanism for normally and reversely rotating a zoom motor which supplies two kinds of drive voltages to contain a total of four control transistors. SOLUTION: In a motor-driven zoom camera, two control transistors Tr10 and Tr4 are connected between a first power supply terminal 1 and a zoom motor 2. Therefore, the motor 2 can be rotated in the normal direction with a first constant voltage E1 by controlling control transistors Tr10 and Tr5 in turned-on states and control transistors Tr3 and Tr4 in turned-off states. On the contrary, when the transistors Tr10 and Tr5 are controlled to turned-off states and the transistors Tr3 and Tr4 are controlled to turned-on states, the motor 2 can be rotated reversely with the voltage E1. In addition, when the transistor Tr5 is controlled to a turned-on state and the transistors Tr10, Tr3, and Tr4 are controlled to turned-off states, the motor 2 can be rotated normally with a second constant voltage E2.

Title: Method and apparatus for controlling terminal dead zone for electromagnetic induction flaw detection
Inventor: ISOBE SHINICHI
IPC: G01N27/87
Filed: 1990-09-05
Abstract: PURPOSE:To enable selection of finer flaws with an S/N ratio improved by a method wherein a shield frequency of a high pass filter is raised in a specified time after the passage of a front end of a metal regular size material is detected and the frequency is lowered thereafter. CONSTITUTION:Alternating voltage generated with an oscillator 101 excites an excitation coil of an excitation unit assembly 200. The voltage detected with a detection probe of the assembly 200 is applied to a phase detector 310, an output of which is inputted into a variable high pass filter 311. In the filter 311, a shield frequency in the filter 311 is changed over automatically by a gate signal from a flaw detection gate generation output circuit 22. In other words, timers 23A and 23B are started by detection signals of the tip and rear of a material 1 to be inspected with a photoelectric switch 12A and the circuit 22 is started or stopped when the time set of both the timers expires. When a gate signal of the circuit 22 is received, the filter 311 is made ready for a filtering with a high shield frequency and when no gate signal is given, the frequency is switched over to a low level.

Title: Array antenna exciting method
Inventor: CHIBA ISAMU
IPC: H01Q3/26
Filed: 1990-09-06
Abstract: PURPOSE:To improve the axial ratio of a circularly polarized wave array antenna by controlling plural exciting phases of the circularly polarized element antenna so that the obtained intensity of the radiated electric fields of the array antenna as to at least three kinds of linearly polarized wave components different in inclinations is set to be equal. CONSTITUTION:A linearly polarized wave having an arbitrary inclination theta1 is generated and the array element electric fields in the circularly polarized wave element antenna are measured. The values of amplitude and a phase in the array element electric fields are set to be a1n and p1n (n=1-N and N: number of array elements) and a frequency is set to a center frequency and the like. When m=2 and m=3, the inclination of the linearly polarized wave is changed to theta2 and theta3, and a2n and p2n or a3n and p3n are obtained. Then, the obtained intensity of the radiated electric fields in the array antenna as to linearly polarized wave components with the inclinations theta1-theta3 are equalized. Thus, an eliptically polarized wave is corrected to the circularly polarized wave so as to improve the axial ratio of the circularly polarized wave array antenna.

IPC: G11B17/028
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To provide the disk chucking mechanism able to reduce the number of parts. SOLUTION: A driving roller 16 in the state of projecting out of an opening hole 11a is supported on the side of its free end by a supporting member 13 fitted turnably around a fulcrum 14a to the back surface side of a disk holding table 11. The supporting member 13 has a supporting body 131 for supporting the driving roller 16 and a spring part 132 provided along an end part of the side of the fulcrum 14a of the supporting body 131.
