Title: Heating cooker
Inventor: CHIKASAWA HIDEO
IPC: F24C3/12
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent unexpected accidents such as clothes including sleeves catching of a burner flame or burning of a face or fingers with the burner flame by providing a quick return means for promoting the restricting operation of a valve at the time of decreasing operation by a gas control means. SOLUTION: A gas controller has a structure that, when constant pressing force due to the spring force of a pressing spring is released upon operation of a cam 15 interlocking with a cock shaft 14, a needle valve is quickly moved to be closed by a return mechanism and gas supplied to a burner is reduced. At the time of ignition, an orifice hole restricts the quantity of gas to have a predetermined ignitable intermediate fire and gradually increases the quantity of gas to have a strong fire by moving the needle valve at a slow timing after ignition. Thus, accidents such as clothes including sleeves catching fire of a burner flame upon ignition or after ignition can be prevented.

Title: Printing apparatus, printing method and recording medium
Inventor: SHU SESHIN
IPC: B41J2/205
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To prevent banding and express gradations smoothly thereby improving an image quality in a printer for monochromic printing. SOLUTION: An ink-jet printer has inks K1-K4 of different densities for black. A recording ratio of each ink is set so that three inks among the inks are used to form dots in a section D including a halftone which is considered to be relatively easily subjected to banding. Accordingly, each raster is formed by three or more nozzles corresponding to the inks in the section D. Even when the nozzle having a characteristic to form dots to a deviated position is included, the whole raster is prevented from being deviated and banding is lessened. Since inks of different densities are prepared, smooth expression of gradations can be realized.
