Filed: 1988-09-14
Abstract: PURPOSE:To increase the storage capacity of the whole disk device by disposing plural sectors continuously without a gap between them on one track and providing a buffer memory capable of reading this sector group at once. CONSTITUTION:In the case of read, a head 2 is allowed to seek for an address of a track 1 specified vai an interface 4. When the head 2 comes to the objective track 1, then it is awaited that the leading part of a sector group containing the objective sector is brought into the position of the head 2, and the whole group is read in the buffer memory 3 to be sent via the interface 4 to a controller. On the other hand, in the case of write, plural sectors are read in the memory 3, and afterward data being transferred from the interface 4 are written in a prescribed address in the memory 3. Subsequently, the head 2 is positioned at the leading part of the sector group to write the data of the memory 3 in the whole sector group. By this method, the storage capacity of the disk can hence be increased.

Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To surely detect the presence of abnormality even for a curl-shaped, or fine and complex pattern by making a microwave to be irradiated circular polarization in inspecting a conductive pattern which is formed on a substrate. SOLUTION: Microwave, for example, inputted into an input/output part 18 is branched by a hybrid ring 10 and inputted into connecting pins 22, 23 with a phase difference of 90 deg. from each other to be connected in a cylindrical body 21. The pins 22, 23 are inserted at a position shifted by 90 deg. from each other, so that the microwave of circular polarization proceeds to an open end part 21b. the microwave irradiated outward is modulated with the conductive pattern 5a of a substrate 5 to be inspected and returns into the cylindrical body 21, so that an output signal is obtained from the nonreflective termination 10a or the input/output part 18. This signal is compared with a reference wave form to inspect whether it is normal or not. The irradiating microwave is of circular polarization, therefore, it has the same effect as the one which irradiates from every direction, thus it is possible to conduct accurate inspection even for a fine and winding pattern.

Filed: 1994-08-31
Abstract: PURPOSE: To increase the number of digits for displaying characters expressing the information on communication without increasing cost by displaying the information on the communication while varying its display area per character. CONSTITUTION: After initialization, the font data of characters expressing the information on the communication are read from a ROM 3 and those font data are extended in a RAM 4 as image data. For this extension from the font data to the image data, the extension is performed so that images corresponding to those font data can be settled within the area shown by previously set font size data. The image data extended in the RAM 4 are applied to an LCD 30 and the LCD 30 displays the characters shown by the image data. When 'FI' is displayed, for example, the 'F' is displayed in the display area corresponding to full angle character width but 'I' is displayed in a display area narrower than the display area of 'F'. Therefore, any large gap is not generated between 'F' and 'I'.
