Title: Vco switching sweep system
Inventor: SUZUKI MASASHIGE
IPC: H03L7/12
Filed: 1988-10-07
Abstract: PURPOSE:To shorten circuit leading-in time in a PLL circuit by sweeping alternately a voltage control oscillator(VCO) to a positive side and a negative side from a center frequency. CONSTITUTION:The control voltage of the VCO which can lead in extending from the center frequency f0 to (f0+DELTAf) is generated by a sweep circuit 1. Also, by allowing its control voltage to pass through an inversion amplifier 2, a control voltage which can lead in extending from f0 to (f0-DELTAf) is obtained. These two control voltages are inputted to a changeover switch 3 and switched at a suitable timing by a leading-in detecting signal and inputted to an adder 4. In the adder 4, its sweep control voltage and a DC component of a phase comparator 6 are added and the control voltage of the VCO 5 is obtained. In such a manner, since two VCO 5 is swept alternately extending from the center frequency f0 to the positive side and the negative side, the leading-in time of a PLL circuit can be shortened.

Filed: 1988-10-07
Abstract: PURPOSE:To reduce the unevenness of a regulation of releasing agent with a simple constitution by forming the edge of a metaling blade in a projecting shape which is nearly coincident with the concaved surface of a fixing roll. CONSTITUTION:The edge 8 of the metaling blade 7 is made to protrude so that the shape thereof nearly coincides with the concaved surface of the fixing roll 1.

Abstract: PROBLEM TO BE SOLVED: To easily evaluate the deformation coefficient of the slack region of the ground of a tunnel or the like and the deep part of the ground by allowing a heavy weight being energized by a spring to hit against the ground surface to be evaluated, for generating deflection in the ground, and measuring the amount of deflection. SOLUTION: A testing machine is installed downward on the road floor of a tunnel or the like. Then, a heavy weight 1 is pulled up against the force of a spring 2 via a handle 8, and a sensor 7 such as an acceleration sensor is mounted. After that, the heavy weight 1 is placed on the ground by utilizing the force of the spring 2. Then, the ground is deflected, and the amount of deflection at that point is measured. For analyzing a numeric value that is measured by the sensor 7, an A/D converter 5 and a personal computer 6 for measurement and analysis are connected to the sensor 7. The amount of deflection at a certain point can be expressed by the function of the coefficient of elasticity, a Poisson ratio, and the thickness of a layer at that point.  Therefore, when the coefficient of elasticity, the Poisson ratio, the thickness of the layer, and the like are known, the amount of deflection can be obtained.

Title: Electron beam generating device
Inventor: SHIRATORI TETSUYA
IPC: H01J31/12
Filed: 1988-10-07
Abstract: PURPOSE:To enable the stable takeout of electron beams and the display of an excellent image of high quality by specifying the relation between the spiral winding pitch of a linear cathode electrode and the contact part length of its support means. CONSTITUTION:The spiral winding pitch of a linear cathode electrode 3 is made smaller than the contact part length of a linear cathode electrode supporting means 4. Even if the linear cathode electrode 3 causes a relative position change to the linear cathode electrode supporting means 4 by its thermal extension and contraction, the support means contact part is never fallen between the linear cathode electrode spiral windings, nor 'catching' is caused. Thus, problems such as the occurrence of continuity with the support means ground metal because of peeling of the oxide electron radiating material, deflection of the linear cathode electrode 3, and chipping of the edge can be prevented. Hence, the electron beams can be stably taken out, and an excellent image of high quality can be stably displayed.
