IPC: G11B5/193
Filed: 1992-12-18
Abstract: PURPOSE:To maximize the magnetic permeability by controlling the residual stress of a magnetic core material at the bonding time. CONSTITUTION:A magnetic gap (g) is formed at a sliding face of a magnetic recording medium between magnetic cores 1 and 2. The length of the gap is set to be 0.2mum.

Title: Method and device for removing disturbance signal from input signal
Inventor: ALAPURANEN PERTTI
IPC: H04B1/10
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To reduce and remove undesirable audible disturbance caused by a burst mode operation by correcting an input signal only on a signal frame where transmission burst exists while a corrected disturbance signal is used. SOLUTION: A disturbance signal is extracted from a digitized audio signal by DSP 6. An adaptive filter block 40 usually gives filter coefficient information 40a to a filter block 34. The outputs of the filter blocks 34 and 40 are given to an output buffer 42 and the output buffer 42 gives an output signal such as a sound signal without interference disturbance, which is generated as the result of a time divisional multiple access(TDMA) operation. An interference detection block detects an input signal part constituted of interference and sets a flag 36 in accordance with interference information. When it is detected that the most part of the input signal block is interference, the input signal block is filtered by the adaptive filter 40.  When the respective coefficients of FIR-ALE 40 are converged, the output of the adaptive filter 40 becomes a signal which substantially has no interference.

Title: Manufacture of metallic parts, and spot welding machine
Inventor: TOKORO TAKEHITO
IPC: B23K11/24
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To manufacture metallic parts composed of a stainless steel by welding without damaging a passive state film of the surface. SOLUTION: This spot welding machine comprises a pair of electrodes 5, 11 arranged to be capable of approaching/separating each other, supply means 13, 17 to supply an inert gas in an area between the electrodes, and a control means to control the current conducting and the supply of the inert gas between a pair of the electrodes 5, 11. The control means stops the supply of the inert gas after a given time passes from the stop of the current conducting. Thus, after the workpiece is cooled to the temperature not to be oxidized in the air, machine parts in a good surface condition are obtained without damaging a passive state film on the surface even when the workpiece is exposed to the air in an oxidization atmosphere.  Further, since the machine parts do not require a special surface treatment such as plating and the like, as a whole, the manufacturing cost of the metallic parts with a welding structure can be reduced.

Title: Floating magnetic head
Inventor: IDO HIROTAKA
IPC: G11B5/127
Filed: 1991-12-28
Abstract: PURPOSE:To improve the contact start stop characteristic by forming a face of a slider attached to the floating magnetic head in contact with the magnetic disk to be wavy. CONSTITUTION:When waviness is provided on a contact face 1a of a slider 1, the distance between the surface of a magnetic disk 4 and the contact face 1a is increased at a recessed part of the waviness, and the projection on the surface of the disk 4 of this part is not in contact with the face 1a. When the period of the waviness is too large, it is required to increase the amplitude of the waviness to some degree and it gives effect onto an access position or the like of a magnetic head with respect to the magnetic disk. Then it is preferred that the period of the waviness is to be 0.1mm-0.5mm (2 cycles/mm-10 cycles/mm). Moreover, a radius (r) of the curvature of the waviness is calculated by a specific equation and the radius (r) is expressed as 31.25mm. As a result, the friction coefficient at start or stop is reduced and the adsorption and wear between the slider and the magnetic disk are suppressed.
