IPC: G03D3/08
Filed: 1981-10-13
Abstract: PURPOSE:To permit starting of the operation without waiting until a developing soln. warms up in a developing method for medical purpose films such as X-ray films by changing the processing time in accordance with the temp. of the developing soln. CONSTITUTION:When a film to be developed is inserted into the device from an inserting plate 1, the film is sandwiched by rolls 22 and 23, and descends in a developing tank. As the film is inverted by a roll 24, it ascends, passes through developing cross racks 25 and enters the next tank 30, from which the film enters a drying section after passing through a rinsing tank. During this time, the film is sandwiched by rolls in the same manner as mentioned above, whereby the film is moved. In the drying section 50, the film is dried by the hot air from air diffusing pipes 52 while it is held sandwiched between drying rolls 53 and  descends. The dried film is drawn into a receiving box 5. The rolls in the device are changed of the number of revolutions by changing the revolutions of motors  by which the film feeding speeds are changed and the processing is controlled  to a proper time.

Title: Heat treatment of stainless steel
Inventor: SHIMIZU HIROSHI
IPC: C21D1/70
Filed: 1989-06-26
Abstract: PURPOSE:To suppress a cost increase caused by the additional installation of coating equipment prior to annealing and to speed up annealing and descaling lines by coating the surface of a stainless steel with the oxide of Fe and Cr and then annealing the stainless steel. CONSTITUTION:The surface of the stainless steel is coated with the oxide of at least either of the Fe and the Cr. The surface is otherwise coated with at least one kind among the hydroxide of the Fe, the hydroxide of the Cr, the oxyhydroxide of the Fe, and the oxyhydroxide of the Cr. The stainless steel is thereafter annealed. The coating is executed by suspending the above- mentioned materials into liquid and applying the soln. on the steel. The endothermic property at the time of the annealing is enhanced in this way and the heating up time is shortened. The direct contact of the atmosphere gas in an annealing furnace and the surface of the stainless steel is hindered, by which the oxide scale on the surface of the stainless steel is thinned and the time for descaling is shortened.

Abstract: PURPOSE:To make the titled device compact by sending focused light flux divided by a half mirror to two plane mirrors arranged so as to be intersected rectangularly and obliquely with the optical axis and displacing one plane mirror by a piezo-electric element to change the optical path. CONSTITUTION:Light from a laser light source 1 is irradiaged to a substance 10 to be measured through colimate lenses L1, L2, a beam splitter 112 and a lens L3 and the reflected light is divided into two light flux consisting of measuring light and reference light by a beam splitter 8 through the lens L3, the beam splitter 112 and a condenser L5.

The plane mirror 12 is inclined by a fine angle theta from the optical axis of the incident light and the reflected light reaches the area sensor 9 with the inclination of 2theta. Since the plane mirror 11 is displaced by a piezo- electric element 5 to change the optical path, the light intensity of each point in an interference area is measured by the area sensor 9 while changing the optical path and prescribed operation is executed.
