Inventor: KITAMURA TETSUYA
IPC: G03G15/05
Filed: 1990-11-15
Abstract: PURPOSE:To make a distance requiring high preciseness maintained definitely between an aperture electrode and a counter electrode by giving tension to the aperture electrode. CONSTITUTION:An aperture electrode 20 is made by interposing an insulating layer 21 between a reference electrode layer 22 and a number of control electrode layers 23, and is equipped with a number of apertures 24 that are arranged in a row. A pair of stands 41 are attached to the opposite sides of the aperture electrode 20. Springs 42 are provided between the stands 41 so that the stands are urged to separate from each other, giving tension to the aperture electrode 20. As the insulation layer 21 is made of high polymeric resin film, the aperture electrode 20 is highly flexible, being liable to deform even with a small, external force applied. However, as the aperture electrode 20 is held with the tension given by the springs 42, it does not deform although the external force is applied, and thereby a gap between the said electrode and a counter electrode is controlled correctly.

IPC: H04N19/91
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To decode an audio coded signal and a still image coded signal within a limited arithmetic capability by dividing decode processing of a still image into 1st to n-th processing sets in advance so as to satisfy a specific condition. SOLUTION: Decoding processing of a still image coded signal is divided, e.g. into 1st to 3rd processing sets, variable length decoding processing for a video bit steam is employed for the 1st processing, inverse quantization processing is employed for the 2nd processing, and iDCT processing is employed for the 3rd processing. Let an arithmetic quantity per unit time Tf required for decoding an audio coded signal be A, and let an arithmetic quantity required for the i-th processing (1<=i<=3) be Vi, then an arithmetic quantity P per unit time Tf permitted for an arithmetic means in common to decode the audio coded signal and the still image coded signal is to satisfy the relation P>=A+Vi with respect to all the variable (i). When the value P does not satisfy this relation, the decoding processing for the still image is divided further.

Title: Information recording medium
Inventor: ISHIBASHI HIROMICHI
IPC: G11B7/2407
Filed: 1992-11-20
Abstract: PURPOSE:To fix recording density over the entire surface of a disk and to enlarge recording capacity by providing first and second track groups while making the number of blocks per track different from each other, and further making the border area of both of track groups wider than the track pitch of both of track groups. CONSTITUTION:Spiral tracks are formed from an inner periphery to an outer periphery on a disk substrate 10 and divided into first and second zones. The fixed number of data blocks (servo areas 2 and 4 and data areas 3 and 5) are formed per track in each zone. On the other hand, since the number of data blocks in each zone is made proportional to a radius where the zone is positioned, recording density is made almost equal for the first zone on the inner periphery side and the second zone on the outer periphery side. Further, since the track pitch in the border area (transient area) between the first and second zones is made wider, influences caused by the cross-talk of a wobble mark are eliminated.

Abstract: PURPOSE:To enable the recessions of fine rugged patterns to be filled up without forming cavities by a method wherein, after forming a thin film, a flattening film is formed and then the process of etching the thin film and flattening film at almost the same etching speed is repeated several times. CONSTITUTION:In such a rugged Si substrate 1, a CVD-SiO2 film (I)2 as a thin film in thickness not to form cavities is formed as shown in figure (B) and then grooves left after forming a resist film (I)3 as a flattening film as well as the CVD-SiO2 film (I)2 are filled up to flatten the surface. Next, the CVD-SiO2 film (I)2 and the resist film (I)3 are etched at almost the same etching speed until the resist film (I)3 is entirely removed but the Si substrate 1 is not etched resultantly to remove the CVD-SiO2 film (I)2 only on the bottom of recessions as shown in figure (C). Likewise, the formation of CVD-SiO2 film 2 and resist film 3 as well as the etching back process are repeated several times so that the recessions in the Si substrate 1 may be filled up with the CVD-SiO2 films in even film quality to flatten the surface of Si substrate.
