Filed: 1982-07-29
Abstract: PURPOSE:To improve filling rate of an active mass by making longer immersing time as the amount of an active mass is increased when the active mass is filled in the substrate by immersing a conductive porous substrate in a cadmium nitrate solution. CONSTITUTION:A substrate prepared by attaching carbonyl nickel to a nickel plated steel punched plate and sintering it is immersed in a cadmium nitrate solution and then held in an alkaline solution and washed and dried, and again immersed in the cadmium nitrate solution. When these processes are repeated in 4-6 cycles to keep the amount of active mass, immersing time makes longer as the amount of active mass is increased in order to make to diffuse a cadmium nitrate solution in pores of the substrate to form a cadmium plate for an alkaline battery. Therefore, sufficient amount of active mass is held in a decreased impregnation cycle, and chemical impregnation process is improved.

Abstract: PROBLEM TO BE SOLVED: To prevent a sealable part from becoming bulged and peeled off in preparing a sealed letter by not making a card part thick, and also make the sealed letter smoothly printable. SOLUTION: Three pieces of paper, i.e., an upper paper 4, an intermediate paper 5 and a lower paper 6, stacked over each other, to form a sealed letter are continuously joined together through perforations 2, 3 for folding. Further, a part 15 intended for the formation of a card is set on a face where the intermediate paper 5 and the lower paper 6 are stacked, then a film 16 of larger in size than a part corresponding to the part 15 on the opposite side face to the intermediate paper 5 is attached to the part corresponding to the part 15, and a perforation 18 is formed along the contour of the part 15 so that the perforation 18 pierces through the film 16 from the stacked face side.  Thus a card part 19 is formed by partitioning it with the perforation 18, and the card part 19 is separable from the intermediate paper 5 with the film 16 for lamination to prevent the card part 19 from becoming thick.

Title: Method for detecting finishing time of dry etching reaction
Inventor: INOUE MINORU
IPC: H01L21/3065
Filed: 1980-09-27
Abstract: PURPOSE:To find out the point of finishing time correctly as well as to prevent an erroneous operation by a method wherein a non-oscillatory rate only is selectively detected among the changing rates of the quantity of light of the plasma light which is generated as characteristics when the reaction of plasma-etching is continued. CONSTITUTION:There is a plasma light which changes as characteristics only when the etching rection is continued in the plasma etching reaction. When this changing rate, i.e., differential value, of the quantity of light against time drop below the fixed value, it is considered as the finished point of time of etching, the curved line b constitutes an oscillatory change b' and this becomes the cause of an erroneous operation. In order to prevent this erroneous operation, a device which always memorizes a differential value and a device to be used to judge whether or not the differential value is an oscillatory one are provided and a reaction suspension command circuit is operated as occasion demands. Through these procedures, the finishing point of time of the etching reaction is detected accurately and an erroneous operation can be prevented.
