Title: Electric discharge machining control method
Inventor: SAWADA KIYOSHI
IPC: G05B19/416
Filed: 1993-02-05
Abstract: PURPOSE:To obtain an electric discharge machining control method having a good responsing property and capable of carrying out stable electric discharge gap control. CONSTITUTION:The condition of electric discharge machining between a tool electrode 1 and a workpiece 2 is detected by a gap condition detector 3. Shunting speed commands V2x to V2z are found by multiplying the difference between the detected value Vg and the target value Vs by the respective axial component of a directional vector 'a' of the shunting direction, these shunting speed commands are added to speed commands V1x to V1z, respectively, which were found by position loop control, and made the speed commands for the speed loop control, respective servo motors 6x to 6z are driven and the gaps are adjusted. The shunting speed commands V2x to V2z are integrated by integrators 10x to 10z, moving quantities when the speed commands are corrected are found, the moving quantity is added to the position moving command input in the position loop and the current position is prevented from being lost. Because speed commands are corrected to have the electric discharge machining condition become a target condition, responsing property is good, as compared with the adjustment made by ever distribution cycle, and a stable electric discharging machining can be accomplished.

Title: Coaxial transmission line
Inventor: ISHITOBI TOKUMASA
IPC: H01P3/06
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To shorten the physical length of a coaxial transmission line to improve its compaction degree regardless of the dielectric material by coaxially arranging plural transmission lines and cascading them together. SOLUTION: An end 10a of a center conductor 10 is connected to an end 12a of a 2nd cylindrical conductor 12, with the other end 10b of the conductor 10 being set at an input terminal and an end 11b of a 1st cylindrical conductor 11 set at an output terminal respectively. With such a constitution, the conductors 10 and 11 form a 1st transmission line and the conductors 11 and 12 form a 2nd transmission line. Then the 1st and 2nd transmission lines are cascaded to each other. Thus is a coaxial transmission line can be obtained, that has its electrical length twice as long as its physical length even though the line appears to be merely a single line from the outside. The physical length of the transmission line is shortened more by loading a dielectric of a high dielectric constant between the conductors.

Title: Heat pipe diverted from freezing device
Inventor: KATAOKA REN
IPC: F02B75/02
Filed: 1980-03-31
Abstract: PURPOSE: To perform heat collection inexpensively and with excellent efficiency by making the freezing device have the effect of the heat pipe.  
     CONSTITUTION: Valves 6 and 7 such as solenoid valves are provided in a freezing circuit bypassing a compressor 1 and an expansion valve 3 respectively. Moreover, an accumulator 5 capable of absorbing the entire refrigerant in the device is arranged on the suction side of the compressor 1 and thereby hydraulic compression is prevented. In the aforesaid constitution, the compressor 1 is operated with the valve 7 opened and the valve 6 closed in the case when the temperature of a heat-receiving part 4 is higher than that of a heat-discharging part 2 and when the part 4 is not positioned lower than the part 2. Since the valve 3 is bypassed, the compressor 1 turns to be a simple circulation pump for the refrigerant, not performing any compressing action, and thus the termal transfer due to the effect of the heat pipe is performed without being restricted by the positional relations between the heat-receiving and heat-discharging parts. In the case when the heat-receiving part 4 is at a higher temperature than the heat-discharging part 2 and is positioned lower than the latter, the valves 6 and 7 are opened without operating the compressor 1, and the vapor of the refrigerant generated in the heat-receiving part 4 is sent to the heat-discharging part 2 through the intermediary of the valve 6, wherein the heat is discharged and the vapor is liquefied, and the refrigerant thus liquefied is made to circulate by the difference in levels. When the heat-receiving part 4 is at lower temperature than the heat-discharging part 2, the valves 6 and 7 are closed and an ordinary freezing cycle operation is conducted.

Abstract: PURPOSE:To solve a problem of occurrence of after-image at a moving picture part by detecting only a true motion signal from an input video signal with noise or flicker superimposed thereon with high accuracy, suppressing the after- image even in a comparatively small motion signal small, different from a conventional noise reducing device, in which noise is reduced by utilizing only the statistic property that as an inter-frame difference signal   is smaller, it is highly possible that the signal is noise and as the difference is larger, it is possible that the signal is a motion component, resulting in causing after-image in the moving picture part. CONSTITUTION:A motion detection circuit 106 discriminates each picture element of an input video signal 101 to be any of the still mode, the moving picture mode and the moving still transient mode. Since different noise reduction is implemented for each mode, k the motion detection circuit 106 controls adaptively a nonlinear circuit 109 depending on the discriminated mode.
