Title: Magnetic head
Inventor: NAKAMURA AKIO
IPC: G11B5/127
Filed: 1978-02-28
Abstract: PURPOSE:To obtain a magnetic head of vertical magnetization system of a narrow track width by  combining a pair of nearly U-form thin plate ferromagnetic material cores and a ferromagnetic  material thin plate which will be an upper bottom part thereby forming the main magnetic pole  core part of the specific shape. CONSTITUTION:A first core 21 and second core 22 of nearly U-form each consisting of an upper  leg part l1, a lower leg part l2 and a connecting part l3 are so combined that the leg part  directions become mutually opposite. A ferromagnetic material thin piece is sandwiched between  the upper leg parts l1, l1 to form an upper bottom part 23 and a spacer of non-magnetic material of high conductivity is sandwiched between the lower leg parts l2, l2 to form a lower bottom  part 24. The lower leg parts are formed by the curving side 20a approaching gently to a medium  26 in the A direction (advancing direction of the magnetic recording medium 26) and the straight  side 2b of the angle theta created with itself and the A direction being 90 deg. or over to form the main  magnetic pole core part. The abovementioned main magnetic pole is opposed to an auxiliary  magnetic pole 27 with the magnetic recording medium 26 in-between, hence the magnetic flux  loop is formed among the upper bottom part 23, first core 21, medium 26, auxiliary magnetic  pole 27, medium 26, second core 22 and upper bottom part 23.

Filed: 1988-02-03
Abstract: PURPOSE:To reduce the quantity of operator's cursor movement and to speed up operation by performing coordinate input and cursor movement to a cursor movement reference point with a button number inputted from a mouse. CONSTITUTION:When a button of the mouse 3 is pressed, a CPU 8 inputs the coordinates (x, y) of the cursor indication difference point and the button number of the pressed button and decides whether this process is a coordinate input process or cursor movement according to the button number. Then when the process is the coordinate input process, the coordinate values (x, y) are inputted and when the cursor movement, the cursor is moved to the cursor movement reference point. This reference point is provided where detailed position specification is performed frequently like a menu display part and then the cursor is moved to the point by single-time button operation. Consequently, the mouse operation is reduced and the operability is improved.

Inventor: TSUBOKAWA MAKOTO
IPC: G02B6/00
Filed: 1991-02-15
Abstract: PURPOSE:To easily recognize a change in the status of an optical cable after the cable is laid by making an optical pulse, the polarized state of which is adjusted, incident to the optical fiber of the optical cable and separating the back scattering light of the pulse into two orthogonally crossing polarized components, and the, photoelectrically detecting at least one of the polarized components.

After entering the lens 15, the light is made incident to a polarizing prism 16 after it is reflected by an opaque mirror 14 and spatially separated into two orthogonally crossing polarized components. The polarized components are respectively photoelectrically converted by means of photoreceptors 17A and 17B and the outputs of the photoreceptors 17A and 17B are averaged by means of a computer The processed results are displayed as the positional function the fiber 2 in the length direction. Therefore, when the intensity change in connection with the position of at least one of the polarized components of the back scattering light is observed, the position and extent of the strain applied to the optical fiber 2 can be estimated.

Filed: 1980-02-26
Abstract: PURPOSE:To always operate the frame synchronizing device normally, by initializing the shift register in the pulse generator and the reference code generator to a specific state by the preset pulse applied from the external if the asynchronous state is discontinuous.

IPC: H04N5/208
Filed: 1988-02-03
Abstract: PURPOSE:To prevent an unnatural contour emphasizing action by changing the passing frequency band of a variable frequency characteristic filter part in accordance with a level fluctuation width. CONSTITUTION:The level fluctuation width at the level sudden change part of a picture signal is detected at a level fluctuation detection part 29 and a detection output is supplied to a filter control part 30. The passing frequency band of a variable frequency characteristic filter part 25 is changed in accordance with the level fluctuation width, for example, so that the lower limit of the passing frequency band may be transferred to a higher side in proportion to the enlargement of a detected level fluctuation width. Consequently, the time width of the contour signal component is controlled in accordance with the level fluctuation width, when the level fluctuation width is comparatively enlarged, the time width of the contour signal component is prevented to be excessive. Thus, it is prevented to be an unnatural emphasis which is caused by emphasizing excessively over a long period.
