Abstract: PURPOSE:To simplify a structure, to provide the characteristics of low side lobe over a wide angle and to enable a wide-band operation by constituting a primary antenna provided on the focus of a rotation parabolodial reflector by metallic conductors wound in a helical form. CONSTITUTION:In this paraboloidal antenna composed of the rotated parabolic reflector and the primary antenna provided on the focus, the metallic conductors 3 and 4 wound in the helical form are used for the primary antenna. That is, the metallic conductor 3 is wound in the helical form counterclockwise at the outer periphery of a cylinder 2; the metallic conductor 4 is wound in the helical form clockwisely at the outer peripheral of the cylinder 2; and the length of one round is turned to be approximately coincident to the center wavelength of radio waves to be used. Then, a balanced current balance-to-unbalance transformed in a slit balun 5 provided in the tip part of a coaxial power feeding line 1 reaches to the power feeding part of the tip part. In this case, the balanced current lead to the metallic conductors 3 and 4 radiates an electric field to a current along a helical rotation direction; circularly polarized waves in mutually reverse rotation directions are superimposed; and linear polized waves are generated.

Title: Method for cooling electromagnetic actuator and electromagnetic actuator
Inventor: KIKUCHI TOSHIHIDE
IPC: H02K9/00
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To evenly and uniformly cool the whole body of an electromagnetic actuator so as to prevent local heat generation and, at the same time, to improve the cooling efficiency of the actuator. SOLUTION: Refrigerant flowing passages are formed in at least two different directions on both sides of flat coils 73 and 74 which generate heat in working states. Consequently, such a temperature gradient that the temperature gradually rises in one direction due to the heat exchange with the coils 73 and 74 is generated in the refrigerant flowing in one direction and another temperature gradient that the temperature gradually rises in the other direction due to the heat exchange with the coils 73 and 74 in the refrigerant flowing in the other direction. Therefore, heat delivery takes place between the coils 73 and 74 based on the temperature gradients generated in the refrigerants flowing in both directions and uniform cooling becomes possible.

Title: Cleaning device for grid member
Inventor: FURUHATA KAZUHIRO
IPC: H01T19/00
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To remove dirt adhering to a grid member stably with time by constituting at least the contact part of a cleaning member with a grid member of thin plate-like high polymer based high strength fiber. SOLUTION: This cleaning member 1 for a grid member 2 is constituted of thin plate-like high polymer based high strength fiber, for example, aramid fiber, etc., and attached to a moving member 3. The cleaning member 1 and the moving member 3 are moved in the laying direction of the grid member through a holder 4 by the rotation of a screw 5 at the time of cleaning operation. By crossing the cleaning member 1 with the grid member 2, the cleaning member 1 comes in substantial point-contact with the grid member 2, and has such a rigidity that it is not deformed to enclose the grid member 2 by pressing. Thus, scraped dirt substance is prevented from being rolled in the contact part of the cleaning member 1 with the grid member 2, consequently, the dirt substance is prevented from being accumulated on the cleaning member 1 or being stuck to the grid member 2 again.

IPC: G05B19/4093
Filed: 1990-03-08
Abstract: PURPOSE:To facilitate the correcting and editing tasks of programs by attaining a constitution where an NC automatic programming processor carries out a sentence every time an execution command is inputted from a one-sentence execution command means and then displays these execution results on the screen of a display device. CONSTITUTION:A one-sentence execution command means is provided to carry out a part program for each sentence together with a re-execution command means. Then the part program to be carried out is displayed on the screen of a display device 7.

Then the processor 1 displays these execution results of sentences on the device 7. When a re-execution command is inputted from a re-execution means after an error of the part program is corrected, the part program is automatically re-executed from the corrected program sentence or the first sentence of the part program through the position of an already executed program sentence or the next program sentence. Then the result of this re-execution is displayed. Thus the part program is corrected and this corrected program can be carried out.

Title: Ignition plug type engine
Inventor: KASAHARA SHINICHIRO
IPC: F02P17/02
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To facilitate release of timing advance control through electronic control without varying connection of an apparatus and using a different jig. SOLUTION: When ON/OFF operation of an ignition switch 3 is effected ten times or more in 30 seconds, a timing advance controller 2 is provided with a function to bring a bypass signal D into an OFF-state outputted to a distributer 4. The bypass signal D is a signal to perform control of a timing advance by a timing advance controller 2 by changing over a control change- over switch 4a in the distributor 4. By bringing the signal into an OFF-state, the distributor 4 invalidates a control signal from the timing advance controller, whereby control of the timing advance by the timing advance controller 2 is released.
