Title: Production of magnetic head
Inventor: MATSUMOTO TOSHIO
IPC: G11B5/255
Filed: 1987-06-22
Abstract: PURPOSE:To facilitate polishing and to decrease the spacing between a head stock and recording surface so that a spacing loss is decreased by removing the hard matter on the floating surface side of a slider by etching, then polishing the floating surface. CONSTITUTION:The slider 1 is formed with the floating surface 4 consisting of an 'AlTiC' material which has the hard matter 2 consisting of TiC and soft matter 3 consisting of, for example, Al2O3. This floating surface 4 is subjected to the etching by a gas prepd. by adding, for example, O2 to CF4 to selectively remove the hard matter 2 prior to the polishing of said surface and thereafter, the polishing is executed. The polishing on the surface 4 side of the slider 1 is, therefore, facilitated and the stock removal of the magnetic head stock 1 is decreased and, therefore, a recessing D2 is decreased and the spacing between the recording medium 21 and the magnetic head stock 11 is decreased, by which the spacing loss is lessened.

Title: Optical external modulator
Inventor: NEGAMI SHOICHI
IPC: G02F1/01
Filed: 1994-06-14
Abstract: PURPOSE:To make it possible to perform the modulation of the polarization plane of incident light even if the polarization state of light is not adjusted by changing the phase difference between the X component and Y component of the light propagating an optical transmission path by a specific quantity. CONSTITUTION:A phase changing part 8 for changing the phase difference of the propagating light by (2m-1)*pi/2 (m is a positive integer) is arranged between the optical transmission paths of two polarization plane modulating sections 11. The incident light on the polarization plane modulating part 11 of the forward side (front side) in the propagation direction of the light is changed into circularly polarized light by passing the phase changing part 8 and is made incident in this polarization state on the polarization plane modulating part 11 in the rear side (rear stage) of the propagation direction of the light when the incident light described above is a linearly polarized light having the axis of polarization horizontal or perpendicular to the direction where the stress is impressed on the light transmission path. The phase difference deviates while the light propagates the phase changing part 8 and changes to the linearly polarized light having the axis of polarization horizontal or perpendicular to the direction where the stress is applied on the light propagation path when the circularly polarized light is made incident from the left. The light propagated by either is always subjected to the polarization plane modulation in such a manner.

Abstract: PURPOSE: To reduce the cost of equipment and treating expenses required to wash activated carbon after activation by treating activated carbon of ≥500°C with a washing liq. of ≥76°C under ordinary pressure.  
     CONSTITUTION: When activated carbon as a hot intermediate product after activation is washed, activated carbon of ≥500°C is directly charged into a washing liq. of ≥76°C under ordinary pressure and washing without cooling or storage unlike a conventional method. As a result, the carbon is instantaneously dipped in the liq. while preventing the breakdown of the granules of the intermediate product and an intermediate product floating phenomenon, and washing operation can be performed at once. Thus, equipment such as a cooler or a storage tank for the intermediate product is made unnecessary, and the consumption of energy, inert gas, etc. required for cooling or storage is throrougly eliminated. By carrying out the same process as that of a conventional method thereafter, activated carbon with high characteristic is obtd.
