Inventor: AIZAWA NOBUHIRO
IPC: G11B5/09
Filed: 1989-12-26
Abstract: PURPOSE:To sufficiently remove the wrong crossovers by shouldering by providing a changeover means which changes over a time domain one-shot width on the inner and outer peripheries of tracks. CONSTITUTION:The changeover circuit X which changes over the time domain O-S width by the tracks on the inner and peripheries of a disk is added to a time domain one-shot circuit 2. A transistor Tr 1 is turned off on the outer periphery of the tracks to set the time domain O-S width at the value A 1 determined by a resistor R 1. The Tr 1 is turned on to set the one-shot width at which the resistor R 1 and the resistor R 2 are paralleled at A2 (A 2<A 1) on the inner periphery. The time domain width is, therefore, increased on the outer periphery where the crossovers are liable to arise frequently and the width is decreased on the inner periphery where the peak shift quantity is large and, therefore, the crossovers are sufficiently removed.

Title: Driving system for display device
Inventor: EBIHARA HEIHACHIRO
IPC: G09G3/36
Filed: 1991-11-26
Abstract: PURPOSE:To apply the same driving voltage to the same display picture element and to prevent an effective value different from becoming narrow owing to waveform distortion by holding a scanning select signal at a nonselection potential until the potential of a column electrode driving voltage becomes nearly stable. CONSTITUTION:The scanning select signal is held at the nonselection potential until potential variation in each column electrode driving voltage Y becomes nearly stable at the leading edge of each selection period. At the trailing edge of each selection period, the scanning select signal is varied to a nonselection potential prior to potential fixation and after the transition almost ends, the potential of each column electrode driving voltage is fixed. Further, the scanning select signal is varied to the nonselection potential prior to the variation in each column electrode driving voltage at the time of in-row inversion and after the potential variation nearly ends, the scanning select signal is varied to the selection potential again. Consequently, a driving voltage waveform which is applied in the selection period is not affected by the column electrode driving voltage stage of a last row and the influence of display data of a next row is eliminated in the process of transition from the selection period to the nonselection period.

Abstract: PROBLEM TO BE SOLVED: To provide a laminated sheet which simultaneously satisfies a nail hole water-stopping property and workability. SOLUTION: The nail hole water-stopping property is ensured by the elongation of a laminated article of a nonwoven fabric layer 2 and a thermoplastic resin layer 1. In this case, for the nonwoven fabric layer 2, ratios of a strength in the larger direction and a strength in the smaller direction are both in a range of 1.0 to 1.5 regarding the tensile strength and the tearing strength in the longitudinal direction and the lateral direction, and both of the elongation percentages in the longitudinal direction and the lateral direction are set to be 50% or higher. Also, for the thermoplastic resin layer 1, both of the elongation percentages in the longitudinal direction and the lateral direction are set to be 50% or higher.  Then, on the laminated article, an elongation control layer 4 is laminated, and the load elongation percentages in the longitudinal direction and the lateral direction are set to be 5% or lower at the time of 20 N/cm of the whole of the sheet. Thus, a slipping feeling at the time of working is eliminated.
