Title: Control device for distributive flow amount share between fluid distribution sources
Inventor: KADOWAKI MASAHITO
IPC: F04B49/06
Filed: 1991-11-08
Abstract: PURPOSE:To prevent generation of trouble in a distribution system due to an uneven distributive flow amount between two fluid distribution sources by determining a share program value based on a demand estimated value and share ratio, and further correcting the share program value to control a distributive pump of each fluid distribution source. CONSTITUTION:Share program values 8, 9 to be distributed of each fluid distribution source are determined by a distribution share program means 42 based on a demand estimated value (b) of distributive flow amount and its preset share ratio 7. Based on a pump start flow amount 12 and pump stop flow amount 13 for correcting the share program values 8, 9, distributive flow amount target values 14, 15 of each fluid distribution source are determined by a share program correcting means 43. A distributing pump P1 is controlled by distributing pump control means 44, 45 to supply a fluid amount, matched with the distributive flow amount target values 14, 15, to a fluid demand source. In this way, a trouble in a distribution system by an uneven distributive flow amount between the two fluid distribution sources can be prevented from being generated.

Title: Support for photographic paper
Inventor: ASAI SEISHI
IPC: G03C1/775
Filed: 1990-10-29
Abstract: PURPOSE:To provide a support for an inexpensive photographic paper without losing of fixing agent and discoloring and with excellent gloss in emulsion processed, and excellent photographic base plate layer fitting characteristic and an excellent emulsion fitting characteristic, by specifying water absorption degree of a paper base. CONSTITUTION:In a support for photographic paper having a photographic base plate layer on a paper base, the water absorption degree of the paper base is set 10 - 20 g/m<2> by the water absorption degree test method (JISP-8140). If the water absorption degree is less than 10g/m<2>, immersion of coating liquid and gelatin into the support plate becomes worse so that the base plate layer is liable to be peeled off. If the degree of liquid absorption is larger than 20g/m<2>, the immersion becomes well so that the fitting condition between the support and the base plate layer becomes well, but the brightness of emulsion processed becomes worse. It is thus possible to provide a photographic paper excellent in its processed emulsion gloss and fitting condition between the support body and the base plate layer as well as between the base plate layer and emulsion.

Title: Prepotency test method for left/right brain and device
Inventor: MATSUZUKA NOBUKADO
IPC: A61B5/16
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To simply perform a prepotency test of the left/right brains by lighting/unlighting left/right light sources installed in the left/right at a prescribed interval by changing its lighting/unlighting state, letting an subject visually recognize respective changes of lighting/unlighting, and judging the significance of the works of the left/right brains based on the results. SOLUTION: When a power supply is turned on and a switch 19 of an operation part 15 is operated, an unlit time control part 14 is operated so that a test light composed of an intermittent light changing only the unlit time is emitted from light sources 12a, 12b at a constant period. This test light is so controlled that the unlit time is shortened hourly from the unlit starting so as to become the continuous light lastly. When a subject views the light sources 12a, 12b in left/right fields of vision respectively, the activity states of the right/ left brains are different in the initial state of the test so that, even if they are the same test light, either one of the light sources 12a, 12b in the fields of vision is recognized as a short intermittent light and lastly recognized as the continuous light. Prepotency of the left/right brains can be thus judged from this results.
