Title: Memory device
Inventor: UEDA TOSHIYUKI
IPC: G11B27/10
Filed: 1985-03-13
Abstract: PURPOSE:To improve the medium production yield by providing a defect detector and skipping means while removing part or all of the data tracks corresponding to defective portions on a servo disk out of use. CONSTITUTION:In a skip address part 31, there are three areas BA1-BA3 storing a byte address BA indicating the data skip leading position on the track, so that up to three defects on the track can be skipped. Hence it becomes possible to skip so as not to write data over an extent of a constant length from a byte position corresponding to the data track in association with the positions where defects 14 of the medium exist on the servo disk 1. When a comparator circuit 9 detects the medium defects, the track in its entirety may be put out of use as track in trouble or a certain length from the leading byte stored in the skip address part 31 may be skipped. In such a manner, use is made possible even if there is defect in the medium so that the production yield is improved.

Title: Liquid crystal element structure for electric field sensor
Inventor: UCHIYAMA AKIHIKO
IPC: G02F1/13
Filed: 1988-03-04
Abstract: PURPOSE:To obtain a liquid crystal element structure which has a low operation threshold by an electric field and can be utilized as a practical electric field sensor by allowing lines of electric force which are entered from an external electrode with large area to pass between opposite internal and external electrodes with small area. CONSTITUTION:A liquid crystal element 101 is constituted by sandwiching liquid crystal 102 between glass substrates 103 and 104, and spacers 105 and 106 and sealing them with sealants 107 and 108. Internal electrodes 109 and 110 and external electrodes 111 and 112 which are larger than said electrodes are provided on the external surface sides of the glass substrates 103 and 104, and those electrodes 109 and 110, and 111 and 112 are connected by connecting lines 113 and 114 respectively. The area ratio of the electrodes 109 and 110, and 111 and 112 are 1:100. When an external electric field is applied to the element 101, lines 115 of electric force which enter the electrodes 111 pass through the connecting line 113, electrode 109, liquid crystal 102, electrode 110, and connecting line 114 and exit from the electrode 112. At this time, the lines 115 of electric force are converged on the part 116 of the liquid crystal 102 sandwiched between the electrodes 109 and 111. Consequently, a higher electric field than the external electric field is produced at the part 116 and the threshold value of the element 101 to an electric field decreases on the whole.
