Title: Automatic focusing camera
Inventor: AOKI TETSUSHI
IPC: G03B17/18
Filed: 1990-03-22
Abstract: PURPOSE:To attain good operability and to take a photograph which an object is not out of focus by permitting a photographer to select automatic-focusing between the finity step and the infinity step with his judgement when the range- finding information for an object is at a default level. CONSTITUTION:This camera is provided with a display controller 280 and a releasing means R. The controller 280 displays a long-distance mode and an infinity mode, based on the input of default information and at the prescribed time intervals; the releasing means R outputs first information, by which a range finder 248 is operated, and second information, by which mode selection is made with the first information outputted. In condition where the display controller 280 displays the long-distance mode with the first information outputted when the second information is detected by the releasing means R, a photographing lens is moved to the finit-focusing position; in condition where the display controller 280 displays the infinity mode when the second information is detected, the photographing lens is moved to an infinit-focusing position. Thus, the automatic focusing camera which has good operability and is free of out-of-focus can be obtained.

Title: Digital signal processing circuit
Inventor: IWAMATSU MASAYUKI
IPC: H03M1/06
Filed: 1987-03-26
Abstract: PURPOSE:To adjust linearity without generating SN deterioration in a D/A converter on the output side by applying a data offset to digitally processed digital signal data and then D/A converting the data. CONSTITUTION:An analog input is A/D-converted by an A/D converter 10 and digitally processed by a digital signal processing part 12 so that frequency characteristics are changed or a component corresponding to a DC is cut off. A data offset component is added to the processed signal by a mixer 14 and the added signal is D/A converted by a D/A converter 16 and then outputted. A data offset value is set so that the most significant bit of an input to the D/A converter 16 is not almost driven within the amplitude range of dark noise transmitted from the digital signal processing part 12. Even it the linearity based upon the most significant bit is adjusted by the D/A converter 16, the increase of noise is not generated, so that the linearity can be adjusted to the best state while preventing the SN ratio from being deteriorated.

Inventor: MAIKERU AANESUTO GAARETSUTO
IPC: B01D53/26
Filed: 1990-03-22
Abstract: PURPOSE: To efficiently separate water vapor from a gaseous mixture by extracting the water vapor from the gaseous mixture by alternately using two absorbents, then separating one component by means of a membrane and using a permeate gas stream to desorb water from the absorbent to be regenerated. CONSTITUTION: Water vapor is extracted from a compressed stream of the gaseous mixture out of a compressor 2 by a first absorbent 34 while a second absorbent 38 is regenerated. Then the gas stream from which generated water is removed is separated by the membrane 20 to produce a permeate gas 24 rich in one main component and a compressed product stream 22 rich in another main component. Then the permeate gas stream 24 is used to desorb water from the absorbent to be regenerated and the regenerated absorbent is repeatedly used instead of the absorbent full of water and the operation is repeated. Consequently, water vapor can be efficiently separated in advance from the gaseous mixture introduced for separation.

IPC: H01J37/02
Filed: 1988-03-30
Abstract: PURPOSE:To prevent drawing position from being affected by accumulated charge of reflected electrons by installing a conductor with a gap immediately before a reflected electron detector and by keeping the conductor at the ground potential. CONSTITUTION:An electron beams 2 for detection position is irradiated to a sample 6, reflected electrons and secondary electrons 7 generated at this time are captured by a detector 8 through a gap of a ground conductor 10, and is processed as positioned information by a signal processor 9. Even when charge is accumulated to an organic substance such as resist adhered to the surface of the reflected electron detector, the range of influence given by electric field due to accumulated charge to the outside of the ground conductor 10 is nearly the same as the gap d. Therefore, positional accuracy of drawing electron beams cannot by reduced. Since electric field of the surface of the reflected electron detector is shut off in reference to the orbit of electron beams, it is possible to perform highly accurate drawing for contamination within mirror caused when the electron rays drawing device is used for a long time.
