IPC: G11B20/12
Filed: 1991-03-08
Abstract: PURPOSE:To reproduce a sub data with high reliability by providing the recording section of the sub data on the nearly central part of a track. CONSTITUTION:In the track formed on a magnetic tape, the recording section of the sub data is provided on the nearly central part of the track where the contact between the head and the tape is most stable.

Title: Fusion sealing method of plug
Inventor: TAKA TOSHIO
IPC: B29L22/00
Filed: 1990-03-19
Abstract: PURPOSE:To improve the sealing property of a plug by melting the surface of the plug, before the plug comes into contact with a film sheet, at the temperature higher by a predetermined value than the melting point of a material of the plug and, thereafter, pressing the film sheet relative to the plug from the symmetrical direction. CONSTITUTION:When a cylindrical plug 2 having an outer diameter 5mmphi or more is fused and sealed between two films or sheets 1 having a thickness of 100mum or more, before the plug 2 comes into contact with the films or sheets 1, the surface of the plug 2 is melted at the temperature higher by 15-80 deg.C than the melting point of a material of the plug 2 and, next, the two films or sheet 1 are pressed to the plug 2 from the symmetrical direction so as to be fused each other. In this instance, by heat melting them from both sides by means of hot plates, it is preferable that they are heat melted such that the resin melted from the plug 2 is pushed out at 0.2-3mm in a state of a tab into the clearance between the two hot plates. Whereby, excellent fusion can be performed for a film sheet having a large thickness or a cylindrical plug having a large diameter.

Title: Multi-frequency common use plane antenna
Inventor: HAISHI MISAO
IPC: H01Q5/40
Filed: 1990-03-19
Abstract: PURPOSE:To cover a broad range frequency area by arranging plural radiation elements for high frequency range or radiation elements for medium frequency in the region formed by radiating elements for low frequency range of a microstrip antenna. CONSTITUTION:Two square cutout windows are arranged in the region formed by radiation elements 2 for low frequency range of a microstrip antenna comprising a ground plane 9 and the element 2 opposite to each other via a 1st dielectric body 6. Moreover, each of radiation elements 3 for high frequency range is arranged to each cutout window region while the elements 3 are parted to some degree from the end of each element 3 so that the element 3 does not contribute to the antenna characteristic. In such a case, when the antenna is used as a 2-frequency common use antenna, since the inter-center distance of each radiation element is smaller than the effective wavelength lambda of a wave in the dielectric body, the antenna is able to suppress the grating lobe. Thus, a broader frequency range is covered.

Title: Spin tub braking method of washing machine
Inventor: KIM JI-HYUN
IPC: D06F49/04
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To minimize generation of a noise by stopping a spin tub so that braking time can get maximal access to safety limit time even at a different rotating speed by impressing an electric current on an armature coil by varying the duty ratio of the electric current by a rotating speed of the spin tub. SOLUTION: In a spin process, when a spin tub is rotated by driving an RS motor (a switch reluctance motor) 10, in a microcomputer 40, an opening- closing condition of a washing machine door is sensed through an ON/OFF condition of a door switch 50. When door opening is sensed, a rotating speed of the spin tub is detected from an output signal of a light sensor installed in the RS motor 10 by the microcomputer 40, and whether or not its rotating speed belongs to a low speed band is judged. When its judgment is YES, the dewatering tube is stopped in a low electric current braking mode. The spin tub is respectively controlled so as to be stopped in an average electric current braking mode when it belongs to a medium speed band and in a high electric current braking mode when it belongs to a high speed band.
