Title: Manufacture of silver halide photographic sensitive material
Inventor: KANETAKE TETSUSHI
IPC: G03C1/795
Filed: 1989-04-20
Abstract: PURPOSE:To enhance dimensional stability against development processing by drying a photosensitive material while maintaining a ratio of a water fraction of the total solid matter to a time necessary for drying it down to a specified value so as to be equal to or higher than a specified ratio, and drying it under a specified relative humidity after the water fraction of the total solid matter has dropped to <=300%, and after drying, heat treating it under a specified atmosphere. CONSTITUTION:A polyester substrate is coated with a hydrophilic colloidal coating fluid and dried while the A/B ratio is kept at a value of >=18, where A is the water fraction (%) of the total solid matter of all the layers formed on the substrate, and B is the time (sec) necessary for drying A down to 8%. It is dried under an atmosphere of <=50% relative humidity while A is $<=300%, that is, from when A drops down to 300%, and after drying, this photographic sensitive material is subjected to heat treatment under an atmosphere of <=1% absolute humidity at a temperature of at lowest 30 deg.C, thus permitting dimensional stability accompanied by the development processing to be improved.

Title: Erroneous operation discriminator circuit in inverter protecting circuit
Inventor: AKAO YOSHIZOU
IPC: H02H7/122
Filed: 1979-08-10
Abstract: PURPOSE:To enable easy judgement of the erroneous operation at an inverter protecting circuit by providing a circuit for discriminating the output of all firing pulses before the discharge current from a smoothing capacitor reaches a detection level. CONSTITUTION:A comparator 10b in a protecting circuit erroneous operation discriminator circuit 13 operates in the same manner as a comparator 10a in a protecting circuit 8. A flip-flop 16 is set to logic 1 by all firing pulses. A latch circuit 14 stores the input state of the latch circuit when a latch instruction is inputted thereto during the existence of the latch instruction. A protecting circuit erroneous operation display circuit 15 displays whether or not the protecting circuit 18 operates erroneously. Since the latch circuit 14 outputs logic 1 when a commutation is actually failed and logic 0 when the protecting circuit 8 erroneously, it connects the output from the latch circuit 14 to the input of the circuit 15, thereby discrimination of the erroneous operation at the protecting curcuit is made possible.

Title: Gas absorption cell
Inventor: HIGUCHI SUEO
IPC: G01N21/03
Filed: 1980-07-24
Abstract: PURPOSE:To prevent the inclusion of gases from the outside during analyzing of gaseous components and perform analysis in a short time by providing a case with a test liquid injecting tube, and analyzing gas supply tube and a holding plate holding an analyzing gas for a constant time. CONSTITUTION:While coloring liquid is being supplied from a coloring liquid injecting tube 6, an internal gas is exhausted from a gas exhaust tube 8, and after the coloring liquid is injected to a constant amount, an analyzing gas is released from a gas inflow tube 9 into the coloring liquid. This gas forms gaseous bubbles in the coloring liquid and these bubbles ascend while contacting with the coloring liquid and accumulate on the bottom surface of a holding plate 11. While the bubbles and the coloring liquid are in contact, the intended component in the gas reacts with the coloring liquid and forms a color. The gaseous components other than the intended component are exhausted from the tube 8. Thereafter, the absorbancy is measured by using the light of the wavelength corresponding to the coloring liquid past the optical path part A of a vessel 1. Thereby, the operation time is reduced considerably, and the inclusion of the gaseous components from the outside is eliminated.
