Title: Production of thin film magnetic head
Inventor: SHIMIZU YOSHIAKI
IPC: G11B5/31
Filed: 1983-07-01
Abstract: PURPOSE:To produce a thin film magnetic head provided with 2mum or more magnetic layer with high etching accuracy by forming lower and upper layers consisting of reactive metal and performing the ion beam etching of a magnetic layer in the atmosphere of mixing gas consisting of inert gas and oxygen gas. CONSTITUTION:When titanium, reactive metal, forming the lower layer 2 and the upper layer 4 and ''Permalloy'' forming the magnetic layer are etched by ion beams in the atmosphere of the mixing gas consisting of argon gas and oxygen gas, the etching rate of the titanium is extremely reduced, but that of the permalloy is not reduced so sharply. Therefore, a pattern of photoresist 5 is formed on the upper surface of the upper part layer 4 and then the formed pattern is etched by ion beams in the atmosphere of argon gas to form the mask pattern of the upper part layer 4. Subsequently, the formed layers are etched by ion beams in the atmosphere of the mixing gas consisting of argon and oxygen. Since the etching rate of the upper part layer 4 is extremely reduced, the thickness of the upper part layer 4 may be thin and the magnetic layer 3 can be etched with high resolution.

Title: Rectangular at vibrator for overtone
Inventor: ENDO HIDEO
IPC: H03H9/19
Filed: 1987-05-18
Abstract: PURPOSE:To lower the CI of the third harmonic wave overtone further by specifying the surface coarseness of the slope so as to prevent the leakage of energy due to the surface coarseness of the slope. CONSTITUTION:The slope 3 is formed in the X direction of the rectangular AT vibrator chip 1 whose external size is <=7mm in the direction X, <=2mm in the Z' direction, <=0.24mm and >=0.12mm in the direction Y' and the surface coarseness of the slope 3 is selected to be <=1.0mum. Thus, even when the size of the vibration chip is made small as <=7mm in the direction X and <=2mm in the direction Z', the CI of the third harmonic overtone is decreased by the energy confinement effect by forming the slope 3 in the X direction and since the surface coarseness of the slope 3 is selected to be 1.0mum or below, the leakage of energy due to the surface coarseness is not caused and the CI of the third harmonic wave overtone is lowered further.

Title: Light beam scanning device
Inventor: ISHIKAWA HIROMI
IPC: H04N1/113
Filed: 1986-05-26
Abstract: PURPOSE:To make an irregularity in pitch which is caused periodically on a scanning surface inconspicuous by providing a means which deflects finely a light beam in a subscanning direction at random on an optical path extending from a light source to a scanning surface through a rotary polygon mirror. CONSTITUTION:The light beam 2 from the beam light source 1 passes through an acoustooptic deflector 3 and is reflected by the rotary polygon mirror 4 to make a main scan on the scanning surface 6 as shown by an arrow B after passing through a scanning lens 5. If a reflecting surface 4a of the polygon mirror 4 tilts, scanning lines on the scanning surface have a periodically irregu larity in pitch. The light beam is deflected finely in the subscanning direction through the deflector 3 after impinging on the polygon mirror, so the periodical irregularity in pitch on the scanning surface can be made inconspicuous.

Title: Skip channel selection system
Inventor: SUGIYAMA KAZUYUKI
IPC: H03J5/02
Filed: 1988-05-17
Abstract: PURPOSE:To prevent misunderstanding of a fault through the appearance of the same position by deciding whether number of positions set with a stop flag is one or below or two or over and incrementing or decrementing all positions one by one when the number is one or below. CONSTITUTION:Whether an input key is an up-key or a down-key is decided in the step 1 and in case of 'YES', whether a position number set with a stop flag is one or below or two or over is decided in the step 7. In case of one position or below, the content of the position register is increased or decreased in the step 9. In case of two position numbers or over, only the stop flag set position is skipped. Thus, an event that the same position always appears due to mis-setting of the stop flag or the like and misunderstanding of a fault is prevented.
