Abstract: PURPOSE:To facilitate an easy change of the eliminating band of high frequency noises, by adhering a dielectric material between a conductor ring passing through a center conductor of a signal line and a pierced hole of a larger diameter than the conductor ring to form a capacitor and attaching the capacitor  to a box storing an electronic device in a free loading/unloading way to vary  the capacity of the capacitor. CONSTITUTION:A dielectric materal 15 is adhered between a conductor ring 13 passing through a conter conductor 9 of a coaxial connector 1 and a pierced hole of a larger diameter than the ring 13. Thus a flat plate type capacitor 17 is obtained. The capacitor 17 is attached to a metallic case 3 forming an electronic device storing box by means of screws 23 in a free loading/unloading way. The capacity of the capacitor 17 is varied in response to the frequency band of high frequency noises produced by the electronic device. Thus a change is facilitated for the noise eliminating band of a high frequency noise eliminating filter. As a result, the noises produced from the electronic device can be completely deleted.

Title: Optical head for optical disk and reproducing method using the same
Inventor: OGAWA MASATSUGU
IPC: G11B7/1369
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To attain a high C/N and to reduce cross talk by reversibly changing the polarizing direction of a laser with a magnetic coil and optionally making horizontal or vertical light incident. SOLUTION: The polarizing direction of a semiconductor laser 5 is rotated 45 deg. via PBSs 3 and 4 by a Faraday rotator 8. Subsequently, the laser enters a Faraday rotator 7, and its polarizing direction is rotated 45 deg. or rotated to be restored to the original 45 deg. in accordance with the magnetizing direction of a magnetic substance. Now, the magnetizing direction of the magnetic substance can electrically reversibly be changed by the magnetic coil 9, and the horizontal light or the vertical light in the polarizing direction can optionally be incident upon a guide groove formed in a magneto-optical disk 1. Moreover, reflected light by the magneto-optical disk 1 after leaving the Faraday rotator 7 is again passed through the Faraday rotators 7 and 8, and is rotated 45 deg. respectively and returned to its original polarizing direction. Consequently, since reproduction in the polarizing direction suitable for a land and a groove can be performed, a high C/N is obtained, and cross talk is reduced.

Abstract: PURPOSE:To uniformize temperature distribution of a material to be recorded by a method wherein the adsorbing surface, with which the material to be recorded keeps contact, of a platen having air suction holes for adsorbing the material to be recorded and holding it in a position located facing a recording head is formed of a low thermal conductive material having thermal conductivity lower than a specified value. CONSTITUTION:A plurality of air suction holes 12 are formed in a platen 25 holding a material 6 to be recorded in a position located facing a recording head 1. The material 6 to be recorded is kept in a state to be adsorbed to the platen 25 through suction of air through the air suction holes 12, and ink is discharged from a recording head 1 toward the material 6 to be recorded to effect recording. The absorbing surface, on which the material 6 to be recorded is adsorbed, of the platen 25 is formed of a material having low thermal conductivity the value of which is lower than 1 [W/m.K]. Even when an amount of ink delivered from the recording head toward the material to be recorded is high, this constitution keeps the temp of an adsorbing surface approximately at an equal value, and prevents unevenness in concentration of the air suction hole from occurring to a recording picture.

CONSTITUTION:Burner ports 22 are provided on a tight ceramic plate 21 and a large number of minute burner ports 23 are provided around the peripheries of respective burner ports. Most part of a fuel gas mixed with primary air supplied from a main burner body 10 passes through burner ports 22 and is ejected from a burner head 20, and a part of the fuel gas passes through minute burner ports 23 and is ejected from the peripheries of the burner ports 22 on the surface of the burner head 20. Since each of the minute burner ports 23 has a large circulation resistance, the ejection speed of the gas which has passed through this port is relatively small, and stabilized lightened flame 26 is formed uniformly around the peripheries of the burner ports 22. Since the burner is constantly ignited by the lightened flame from the root sides uniformly around the peripheries surrounding the burner ports 22, main flames 25 do not lift even if the gas quantity increases. The ceramic plate 21 is prepared by tightly sintering ceramics of silicon carbide or the like. The diameter of each burner port is 2-3mm while the pitch thereof is 4-5mm, and the diameter of each minute burner port is 0.4-0.8mm.
