Title: Formation of resist pattern
IPC: G03F7/004
Filed: 1992-03-26
Abstract: PURPOSE:To obtain a resist pattern having clear end face profile and no burr or reverse taper by performing a processing for making the primary exposed part of photoresist insoluble to developer and then performing secondary exposure with negative and positive photomasks being inverted thereafter performing the development. CONSTITUTION:A substrate 1 is supplied with positive photoresist 2 which is then primarily exposed by ultraviolet ray through a positive photomask 41. Primarily exposed part 31 is then made insoluble to developer through processing with amine gas. Secondary exposure is then performed by ultraviolet ray 5 through a negative photomask 42, i.e., an inverted photomask of the positive photomask 41. Secondarily exposed part 32 is soluble to the developer. After performing development, a resist pattern 6 is left. Since reverse tapers produced, respectively, through primary and secondary exposure at the end face of pattern are offset each other, a resist pattern having clear end face profile and no burr or reverse taper can be formed.

Abstract: PURPOSE:To eliminate the color shading in a periphery and to obtain an sufficient resolution degrees at the center and the periphery by making a pitch of a color separation filter arranged on the front of an image pickup surface coarser in the periphery than at the center. CONSTITUTION:A stripe pitch of a color separation stripe filter arranged on a front of an image pickup tube 1 used for an electronic index system is fine at the center and becomes coarser as to go toward right and left peripheries. Assuming that the scanning horizontal width of a carrier frequency fc1 of a chrominance signal C1 from the image pickup tube 1 is H, the carrier frequency fc1 changes as shown in the figure in accordance with a horizontal position (-H/2-+H/2). A composite signal is supplied to a variable LPF12 and a luminance signal Y is sampled. A horizontal synchronizing signal from a horizontal synchronizing signal generator 4 is supplied to a filter 12, and its cut-off frequency is made variable in accordance with the horizontal position. At this time, for instance, if the cut-off frequency is selected at a high level so that the chrominance signal C1 can be cut at the center, a resolution degree rises, whereas the picture quality is deteriorated. The prevent this, the cut-off frequency is made variable so that it can be higher at the center and lower as to go toward right and left peripheries, the mixing of the chrominance signal C1 in the periphery can be prevented, and a sufficient resolution degree at the center can be obtained.

IPC: B23K3/04
Filed: 1980-05-26
Abstract: PURPOSE: To facilitate brazing and prevent lack of braze run by increasing the heat absorption of a member of a smaller surface area per unit weight out of brazing members in vacuum brazing for articles consisting of metals of high reflectivity on surfaces.  
     CONSTITUTION: If there is a difference in surface area per unit weight between target parts in the case of performing vacuum brazing of articles consisting of metals of high reflectivity on surfaces such as aluminum and its alloy or stainless steel, blackening treatment which does not hamper vacuum brazing is applied on the surfaces of the parts of a smaller surface area per unit weight and vacuum brazing is accomplished. If the parts are of a stainless steel material, known means such as a chromic acid oxidation method, a sulfide staining method, and acidic blackening oxidation method are used and if the parts are of aluminum, arbitrary means such as an anodic oxidation method are used. Thereby, the uniform brazing temp. is attained in spite of existence of a difference in surface area per unit weight between the target articles.
