Title: Mold for molding ceramic
Inventor: SUGASE AKIRA
IPC: B28B3/02
Filed: 1988-06-22
Abstract: PURPOSE:To enable mold release to be achieved, while the surface of a ceramic molded object is prevented from generating pin holes, and then said surface is not broken n mold release and is kept in the state as it is by forming a prescribed grooves on the corresponding inner surface of a top force or a bottom force. CONSTITUTION:On the inner surface of a top force 11a or a bottom force 11b constituting a mold 11, many grooves 14 are formed. Each groove is directly formed on the mold face of the top force 11a or the bottom force 11b, and is formed so as to be parallel with the direction of the relative movement of the top force 11a or the bottom force 11b. Each groove 14 is formed so that its width and depth are 0.05-0.2mm and its pitch distance is 0.1-0.4mm. Consequently, since the air contained in ceramic material 20 is pushed into an air-well 15 under pressurizing, this air does not make the cause of generating pin holes, etc., and the defect on the surface is prevented. Since the air in the air-well 15 having been pressurized in pushing, is released from pressurizing in mold release, said air accelerates the effect for separating the ceramic material 20 from the bottom force 11b.

Filed: 1980-10-31
Abstract: PURPOSE:To improve the exposure sensitivity of a photoresist film and to minimize the machining irregularity of the line width of an extremely fine size by setting the thickness of the film to a mask blank to the thickness of minimizing the spectral reflectivity in the exposure wavelength. CONSTITUTION:A spectral reflectivity is measured in an actual exposure wavelenth in a range of coated film thickness indexed by the pinhole of the resist and the resolution to set the thickness of minimizing the reflectivity of a film. For example, a positive quinone diazide series resist is coated on a Cr mask plate of, for example, 50% of reflectivity by varying the thickness in the above range, is exposed and developed with coherent light of 436nm in wavelength and is measured in its relfectivity to conform to minimize the thickness dependability of the line width with the thickness of minimizing the reflectivity. When the thickness of the resist is set to that of minimizing the reflectivity, the exposure efficiency can be increased to improve the apparent resist sensitivity, and the irregularity of matching line width can be reduced even if there is slight irregularity in the thickness.
