Title: Camera capable of trimming
Inventor: INOUE MANABU
IPC: G03B17/24
Filed: 1986-01-13
Abstract: PURPOSE:To easily detect a telephotographic effect of a print obtained by trimming or the depth of field by displaying an equivalent focal distance or an equivalent stop value on a display means in accordance with trimming size. CONSTITUTION:In an equivalent focal distance calculating routine, an equivalent focal distance is calculated on the basis of a focal distance of a lens and trimming size, a shutter speed Tv and a stop value Av are inputted and information such as a photographing mode, a trimming mode, the loading state of a lens LN, and the opening/closing state of a back cover 19 is inputted. When a photometric value based upon a photometric part LM is inputted to an input port Ilm, an exposure calculating routine calculates the shutter speed Tv and the stop value Av on the basis of the photometric value and calculates also the equivalent stop value. These calculated results and the equivalent focal distance are displayed on a display unit LD1.

Title: Method and equipment for etching al alloy
Inventor: MIZUTANI TATSUMI
IPC: H01L21/302
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To reduce etching residue without decreasing the selective ratio to resist, by adding a specific time base modulation period to an RF bias which is applied to a specimen stand in order to accelerate ions entering a specimen. SOLUTION: In a method for modulating high frequency (RF) power with time, the RF bias power is decreased at the time when nuclei of residue begin to form. The period of time base modulation is set as follows; the time when the RF bias power is zero or smaller than the means power is 5ms-2.5s, and the time when the RF bias power is larger than the mean value is 5ms-2.5s. Hence the period of modulation is set at least 10ms-5s. The effect of residue reduction is obtained in this range. According to the result of experiment, the effect is confirmed in the case of period of 10ms-5s. The more distinctive effect is obtained in the case of period of 50ms-1s.
