Title: Photosensitive polymerizable composition
Inventor: TANAKA JUN
IPC: G03F7/038
Filed: 1987-05-08
Abstract: PURPOSE:To form a photosensitive polymerizable compsn. which provides finally cured film soluble in an org. solvent when the compsn. is imidized by heating, by constituting the compsn. primarily of a polyamide acid having a specified recurrent unit as its constituting unit. CONSTITUTION:Polyamide acid constituting the photosensitive compsn. of this invention comprises recurrent units expressed by the formula as constituting unit. In the formula, R<1> is an aromatic group; R<2> is a divalent org. group; each R<3>-R<6> is H or a lower alkyl group. Preferred amt. of a sensitizer to be contained in the compsn. is >=0.1 and <=50pts.wt. per 100pts.wt. polyamide acid. If the amt. exceeds this range, the developability and the film forming property of the compsn. are affected adversely. By this constitution, a photosensitive polymerizable compsn. exhibiting solubility in an org. solvent even for a finally cured film formed therefrom is provided. Since stripping of the film is facilitated if the compsn. is used, the film is suitable for protective film of a semiconductor element, etc.

Title: Structure of electrode having constant speed and specified reflectivity
Inventor: PIITAA RAITO
IPC: H03H9/145
Filed: 1991-04-17
Abstract: PURPOSE: To configure electrodes for a surface acoustic wave offering a constant speed, without reflection by selecting an interval of 3λ/4 between centers of 1st electrodes and selecting an interval of λ/4 between centers of 2nd electrodes. CONSTITUTION: Center distance of two first electrodes 22, 24 is selected as 6λ/8 and a surface acoustic wave travelling from the electrode 22 to the electrode 24 and reflected therein travels 2×6λ/8 or 12λ/8, that is (1+1/2)λ. This means that a reflected wave reaches with a phase of 180 deg. difference from an original travelling wave. Electrodes 26, 28 have a width of λ/8 and are spaced by a free space of λ/8. A transduced wave started from the electrode 26 to the electrode 28 and reflected to the start point travels by a distance of 2λ/4, that is, λ/4, and this indicates that the travelling distance is a half of one cycle, and the phase of the reflected wave differs from the phase of the transduced wave by 180 deg. for cancelling it. Thus, while the velocity of the surface acoustic wave is constant, the structure of the electrodes is realized with either the reflectance that is 0 or with a prescribed variable reflectance.

Abstract: PURPOSE:To record a tape pattern same as that obtained by a head azimuth recording/reproducing device divided into two parts at 180 deg. with high productivity, by setting a composite head on an electrical-mechanical transducer and controlling this transducer to change the position of said head in the direction vertical to its revolving surface for each revolution. CONSTITUTION:A piezoelectric element plate 4 containing a head is set on a rotary drum 5 which revolves toward an arrow Y to serve as a rotary head. This rotary head scans a tape 6 traveling toward an arrow Z to record and reproduce signals. At the outset a head 1 starts scanning the tape 6 from a position 8' and ends the scan at a position 7'. Meanwhile a head gap 2 records the video signals produced from an image pickup device 11 to the tape 6. The element 4 moves toward an arrow X until a head gap 3 reaches the position of the gap 2. Then the head 1 starts again to scan the tape 6 at the position 8' and finishes the scan at the position 7'. Meanwhile the gap 3 having a different azimuth from the head 2 records video signals. Thus tracks A1, B1, A2, B2-are recorded equidistantly by (l) on the tape 6.
