Title: System for limiting entrance to platform
Inventor: KAWAI YOSHINORI
IPC: G08B21/00
Filed: 1977-12-14
Abstract: PURPOSE:To safely and efficiently allow passengers to ride off or in the arrived train at a platform by estimating the number of ride enable passengers in the train, detecting the number of waiting passengers on the platform, comparing the estimated number with the detected number of the passengers, and closing gate means when the number of the waiting passengers reaches the number of the ride enable passengers in the train. CONSTITUTION:When a train 2 finishes to ride passengers in to start from a platform, a train departure detector 10 detects it to produce a departure signal to a central controller 11, which thereupon produces a gate closure release signal to gate means 6 and entrance enable signal to a guide indicator 8 and broadcasting unit 9. The number of passengers passed through the gate is detected by a gate passage detector 7 and fed to the controller 11. The number of ride enable passengers at that time is determined from stored passenger schedule, and compared with the number of the waiting passengers passed through the gate means. When the number of the waiting passengers reaches the number of ride enable passengers, a closure signal is applied to the gate means 6.

Title: Air-supply water-saving type hydraulic turbine
Inventor: KANAYAMA MURA
IPC: F01D1/02
Filed: 1986-06-27
Abstract: PURPOSE:To achieve the reduction in the consumption of water quantity and the miniaturization in equipment by injecting the impulse due to the differential pressure between atmospheric pressure and hydraulic pressure as an impulse wave through a nozzle to turn a turbine. CONSTITUTION:A hydraulic pressure receiving part 3 is made possible to be interrupted by a driving body 2. Further, one or more through hole or holes or cutout parts 4 are provided in the driving body 2, and it is so contrived that, when the driving body 2 is turned by a motor 6, the hydraulic pressure receiving part 3 is intermittently communicated with a nozzle 5 via the through holes 4 or the like. In this case, atmospheric pressure is acted on the through holes 4 or the like so that an impulse due to the differential pressure between them and the hydraulic pressure receiving part 3 can be caused. And the impulse due to the differential pressure is acted on a rotating body 1 as impulse wave through the nozzle 5 to turn the rotating body 1. Thus, since the rotating body 1 is turned by injecting the impulse due to the differential pressure between atmospheric pressure hydraulic pressure as an impulse wave through the nozzle 5, the reduction in the consumption of water quantity and the miniaturization in equipment can be achieved.

Abstract: PURPOSE:To improve the fixing characteristic of a toner by incorporating a polar polymer, polymer having the polarity weaker than the polarity of the polar polymer and release agent, forming an image on a substrate by using such toner and fixing the image by heating. CONSTITUTION:This toner is obtd. by mixing the polar polymer, release agent, coloring agent and polymn. initiator with a monomer which provides a non- polar polymer, dispersing the resultant mixture into an aq. dispersant and subjecting the dispersion to suspension polymn. The monomer which provides the non-polar polymer includes styrene, o-methyl styrene, m-methyl styrene, etc. Either of a cationic polymer or anionic polymer is used for the polar polymer and polyfluoroethylene, fluororesin and fluorocarbon oil are used for the release agent. Coloring agents such as carbon black and phthalocyanine are mixed with the polymerizable mixture and azobis isobutylnitrile and benzoyl peroxide are mixed as the polymn. initiator. Both the developability and fixability are thus improved.
