Title: Processing method for silver halide photosensitive material
Inventor: NAKAMURA TAKASHI
IPC: G03C7/42
Filed: 1991-03-01
Abstract: PURPOSE:To decrease the amt. of the fixation replenishing liquid to be replenished without generating a desilvering defect, etc., by executing fixation processing in a multichamber processing tank and replenishing the fixation replenishing liquid in the direction reverse from the direction where a photosensitive material is transported. CONSTITUTION:A small amt. of the fresh fixation replenishing (f) flows from a liquid feed port 11 through a passage 48 into a lower processing chamber 10D, flows successively through a passage 47, a processing chamber 10C, a passage 46, a processing chamber 10B and a passage 45 into a processing chamber 10A and is allowed to flow over from a liquid discharge port 12. On the other hand, the photosensitive material S is transported in order of the processing chambers 10A, 10B...10E. Then, the flow direction of the fixation replenishing liquid is reverse from the transportation direction of the photosensitive material S and the fixation efficiency is enhanced. The consumption of the fixation replenishing liquid (f) is more decreased at the time of obtaining a specified fixing effect. Further, the respective passages 45 to 48 are narrow in width, flow of the fixer more than the necessary flow does not arise between the adjacent processing chambers and the fresh liquid compsn. gradient of the fixer is maintained. The fixing efficiency is thus improved.

Title: Vibration resisting rubber device
Inventor: ISOTANI KIYOSHI
IPC: F16F13/20
Filed: 1979-05-10
Abstract: PURPOSE:To obtain sufficient vibration resisting effect for wide frequency range by providing a pair of frames having wall surfaces confronting to each other, an annular wall member to form a chamber space in cooperation with the wall surfaces of the frames, and a stopper member for resisting the compression of the annular wall member. CONSTITUTION:When vibration is applied to between frames 1 and 2, an annular wall member 11 is compressed to restrict the transmission of vibration with high frequency and small magnitude between the frames 1 and 2. With the compression of the member 11, air contained in a chamber space 14 enters into a chamber space 15 through an orifice 16, and the fluid resistance occured at this time leads to the attenuation effect against vibration of low frequency and medium magnitude. Further, when the annular wall member 11 is compressed to a predetermined level, its deformation is stopped by means of a stopper 19 and the orifice 16 is closed, so that the chamber space 14 constitutes an air spring and then the spring constant of a total vibration restricting rubber device is increased. Thus, vibration of low frequency and large magnitude is effectively attenuated at this time.

Title: Optical reader
Inventor: SAITO HIROSHI
IPC: G06K7/10
Filed: 1985-03-22
Abstract: PURPOSE:To reduce the amount of noise component mixed into the reflection beam light by having the difference between a scan optical path reaching up to a surface to be scanned and a reflection optical path reaching up to a photoelectric transduser. CONSTITUTION:A beam condenser lens 8 is set between a scanning rotary polyhedral mirror 3 and a scan subject 5. The lens 8 has a function to focus the laser beam light onto a surface 5a to be scanned as well as a function to lead the laser beam light reflected on the surface 5a to a condenser rotary polyhedral mirror 4 approximately in the form of parallel luminous fluxes. Then both mirrors 3 and 4 are revolved by a motor 1 synchronously with each other. Thus the laser beam light reflected from the surface 5a illuminated by the laser beam can be condensed. Then the noise components due to a fact that no difference exists between the scan and reflection optical paths can be reduced since both optical paths are different from each other.
