摘要:
In a camera functioning with film speed data introduced by a manual operation for setting desired film speed data, exposure time data is set by a manual operation, and one of the film speed data and the exposure time data are alternatively indicated. The first and second indicating means are controlled, in response to first setting means such that the film speed data appears at the first indicating means when the first setting means is manually operated. The exposure time data is selected to appear at the first indicating means when the first setting means is not manually operated. The second indicating means is disabled when the first setting means is manually operated so that the film speed data appears without appearance of the additional data. The second indicating means is enabled so that the additional data appears with the exposure time data when the first setting means is not manually operated.
摘要:
A variety of substances are known which induce or alter host resistance to coccic and bacillic infections. It is also known that treatment is complicated by the ability of such organisms to develop resistance to antimicrobials. Numerous strains are known which elaborate enzymes in response to these drugs and thus remain insensitive to them. Hence there appears to be a never-ending demand for anti-coccic and anti-bacillic factors. Certain substituted benzoic acids are shown herein to render the host immune to such strains.

摘要:
Regeneration of an exhausted chromium-plating solution can be effectively effected by two-stage diaphragm electrolysis. For the first electrolysis, the anode compartment is charged with a diluted aqueous chromic acid solution and the cathode compartment is charged with an exhausted chromium-plating solution. After the first electrolysis, the solution obtained in the cathode compartment is transferred into the anode compartment which has been emptied by withdrawing the electrolytic solution obtained by the first electrolysis, and the cathode compartment is charged with an exhausted chromium-plating solution. Then, the second electrolysis is conducted. When each electrolysis is finished, regenerated solution useful as a chromium-plating solution is obtained. Some modifications are effective not only for regeneration of an exhausted chromium-plating solution but also for prevention of environmental pollution.
