IPC: G03F7/031
Filed: 1991-01-25
Abstract: PURPOSE:To obtain the photosensitive resin composition capable of forming a relief pattern high in resolution and low in elastic modulus and superior in heat resistance and electric characteristics by incorporating a polymer comprising repeating units of tetracarboxylic acid dihydrate or its derivative having siloxane group as main components.

Title: Gas range
Inventor: MOMOSE TOSHISHIGE
IPC: F24C3/10
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a harmful gas by broadening a clearance on the front side thereof between a burner body and the inner circumferential rim of a juice receiving tray to pass a more amount of secondary air through the front side portion of the clearance than other parts thereof. SOLUTION: A cook stands in front of a range base 7 to operates a dial 8 for operating a gas cock or to conduct a cooking holding a grip of a Chinese cooking pan 6. An upright wall 3 for shielding flame is formed at a part on the foreground side as viewed from the cook on a circumferential frame of a fire crest 2 of a ring burner provided at the center of the range base 7. In a gas range for Chinese cooking thus arranged, a part 5a on the upstream front side of a clearance 5 between the burner body and the inner circumferential rim of a juice receiving tray 4 is broadened more than other parts so that a more amount of secondary air can pass through the part 5a than other parts. Thus, flame formed on this front side is made shorter to prevent incomplete combustion which otherwise may be caused when a flame accidentally touches the upright wall 3.

Title: Magneto-optical recording disk device
Inventor: TANIGUCHI SHOJI
IPC: G11B11/10
Filed: 1992-04-08
Abstract: PURPOSE:To minimize the fluctuation in the intensity of a bias magnetic field by the leakage magnetic flux of an optical head by negating the leakage flux from the optical head by utilizing the leakage magnetic flux from the magnetic circuit of a linear motor. CONSTITUTION:The N pole and S pole of a permanent magnet 10 are properly disposed in such a manner that the leakage magnetic flux PHID from the magnetic circuit of the linear motor 6 is generated in the direction reverse from the leakage magnetic flux PHIC from the optical head 3 so that the leakage magnetic flux PHIC and the leakage magnetic flux PHID negate each other. The leakage magnetic flux PHIC in the recording film 1a of the magneto-optical disk 1 is eventually decreased by as much as the leakage magnetic flux PHID. As a result, the influence on the bias magnetic field applied from a bias magnetic field generating part 4 to a recording film 1a is minimized and the drastic fluctuation in the intensity of the bias magnetic field is obviated.

Abstract: PROBLEM TO BE SOLVED: To prevent a mass of paper dust on a guide from being adsorbed to a separate roller without chaging a position of the paper guide by hollowing a lower position of the separate roller of a first paper feeding means on top of the paper guide. SOLUTION: A conical recess 4a is formed on the top part of a paper guide 4, and a mass of paper dust D dropping from an airspace between two guide plates 20 and 21 is collected in this recess 4a which is situated just under a separate roller 2 of a first paper feeding means, and since a distance between the paper dust D in the recess 4a and the separate roller 2 grows larger, the paper dust D will in no case be adsorbed to the separate roller 2 by dint of electrostatic force. On the other hand, since an overall position of the paper guide 4 is not lowered down, any turn of transfer paper from both second and third paper feeding means is can be done accurately. In brief, and upper end of a conveyor surface 4b of the paper guide 4 is reached to a position where it does not interfere with the guide plate 21, so that conveyance of the transfer paper is stably performable.
