Title: Formatting method and data writing method for disk recording medium
Inventor: GOTOU NATSUHIRO
IPC: G11B20/12
Filed: 1993-04-09
Abstract: PURPOSE:To prevent a medium which is formatted incompletely from being used and detect the incompletion by erasing all DMA information first after formatting is started, and writing defect control information in all DMAs lastly and then comparing contents of DDS and PDL areas of the respective DMAs. CONSTITUTION:After the formatting is started, the DMAs at the inner and outer peripheries are erased first. Then all tracks in a read/write area are erased and written in the order of DMA at the inner periphery, a user area, and DMAs at the outer periphery. After the writing, the written data are read out and inspected to check whether or not there is a defect, sector by sector. Then DMA information is written in four DMAs 1-4 at the inner and outer peripheries. At this time, an error check sector position information is registered in PDL area, and the contents of DDS and PDLs of the DMAs 1-4 are compared with each other. When the contents of more than properly selected numbers of DDSs and PDLs match each other, the end of the formatting is reported, but when not an error signal is sent out.

Title: Rotating mirror optical deflector
Inventor: KAMIYA KIYOSHI
IPC: G03G15/04
Filed: 1982-06-24
Abstract: PURPOSE:To realize a high speed, high precision, and long life by supporting a spindle fitted with a polygon mirror radially by two dynamic pressure air journal bearings, and axially by a magnetic thrust bearing axially, respectively. CONSTITUTION:The spindle 25 inserted into a cylindrical housing 1 having a hollow part and fitted with the polygon mirror 39 is floated axially by the magnetic thrust bearing 29. The magnetic thrust bearing 29 holds a magnetic bearing rotator 26 by horizontal suction force. When the spindle 25 is driven by a rotation driving device 36 to rotate, initial starting torque is only the sliding friction forces of the 1st and the 2nd dynamic pressure air journal bearings 7 and 13. As the spindle 25 increases in rotating speed, dynamic pressure is generated through the operation of grooves formed in the outer circumference of the spindle 25 corresponding to the bearings 7 and 13 to support the spindle 25 radially without contact.

Title: Underground buried body survey device
Inventor: ICHIMURA YASUHIKO
IPC: G01S13/88
Filed: 1988-05-02
Abstract: PURPOSE:To discriminate between an underground buried body, and rocks and other bodies and to survey the burying direction of the underground body by allowing a traction carriage provided with a transmitting antenna and a receiving antenna to move in an optional direction. CONSTITUTION:The traction carriage 1 is towed along a specific survey line y13. At this time, a radio wave pulse is sent from the transmitting antenna 5 into the ground. When the carriage 1 moves to above the buried body 7, the radio wave is reflected by the buried body 7 a received by the receiving antenna 6, and survey data i sent to a device main body 10 through a communication cable 8. The device 10 finds the distance to the buried body 7 and its position and displays them on a device 11 by using a hyperbola. When the peak of the hyperbola is displayed 11, the carriage 1 is moved in every direction about the position P. When the carriage 1 is towed in a direction y' parallel to the buried body 7, the peak continues in the image and when the carriage is towed in a direction y'' leaving the buried body 7, the peak decreases; and this operation is repeated to easily discriminate whether or not there is the buried body 7.

Title: Active matrix display device and its driving method
Inventor: MAEKAWA TOSHIICHI
IPC: G09G3/36
Filed: 1994-04-22
Abstract: PURPOSE:To suppress potential fluctuations of a video line accompanying an increase in sampling rate. CONSTITUTION:The active matrix display device is equipped with row gate lines X, column signal lines Y, and liquid crystal pixels LC arranged at their intersection parts in a matrix. A V-driver 1 scans the respective gate lines X in sequence and selects liquid crystal pixels LC of one line at each horizontal period. An H-driver 4 samples a video signal VISG of each signal line Y and writes the video signal VSIG in the liquid crystal pixels LC of one line selected in each horizontal period. A precharging means 5 supplies a specific precharge signal VPS to the respective signal lines Y right before writing the video signal to the liquid crystal pixels LC of the one line. Consequently, the charging/ discharging capacity of each signal line Y is reducible when the video signal VSIG is sampled, and the potential fluctuations of the video line 2 can be suppressed.

Abstract: PURPOSE:To prevent flickering by dividing one frame into four fields and setting them with a specific display, and making a display with proper gradations on two pixels. CONSTITUTION:One frame is displayed while divided into four fields. The polarities of the driving voltages to a pixel in the 1st - 4th are set to +, +, -, and -; +, -, -, and +; - - +, and +; or -, +, +, and - in the field order; when there are two pixels whose most significant bit of a digital video input signal displayed on four right, left, upper, and lower adjacent pixels is '0' or '1', a display with gradations as many as or one less than the high-order (m)-bit value of the input signal is made on the two pixels in common as to each field. Here, m >= 1. Consequently, four upper, lower, right, and left adjacent picture elements are displayed equivalently with the same gradation throughout one frame to make flickering hard to occur.
