Title: Fluid valve
Inventor: YAMAMOTO NAOYUKI
IPC: F16K5/06
Filed: 1983-02-14
Abstract: PURPOSE:To obtain a fluid valve of ball valve type having a flow regulating function, by drilling a flow path, having a sectional area in the upstream side larger than that in the downstream side, in a ball valve and slidably providing a valve body pressed to the upstream side by a spring. CONSTITUTION:The sectional area of a flow path 10 in its upstream side is spread wider than that in its downstream side, and a valve body 11, positioned in the inside of the upstream side of the flow path, is pressed by a spring 12 toward the upstream side under the condition such that a pressure receiving face 11b of the valve body 11 is faced to a plug screw 1b. That is, plural ribs 13a in the centripetal direction are integrally molded with a supporting ring 13 screwed to the outlet end of a ball valve 2, and the point end of a guide bar 14 supported to the center of the flow path by said ribs 13a is inserted into a center hole 11a of the valve body 11. If a pressure in the upstream side increases higher, the valve body 11, forcing the spring 12 to be contracted and moving rightward, causes the flow path area to decrease narrower, while if the pressure in the upstream side decreases lower, the valve body 11, moving leftward, causes the flow path area to increase wider, thus a flow in the downstream side can be held to an almost fixed amount.

Title: Gas leak protection device when flame goes out not by switch during burning of gas
Inventor: AWAMURA YUTAKA
IPC: F23N5/24
Filed: 1983-02-13
Abstract: PURPOSE:To prevent the gas leak accident from occurring by a method wherein a gas switch gear is actuated by means of steam pressure. CONSTITUTION:The water 35 flowing through a metal pipe 14 from a water feeding device is collected in the metal pipe 41 of a steam generating device. When the disc 46 of a switch gear is depressed, a switching cylinder 64 is lowered so that a cylinder hole 77 coincides with the gas hole 63 of a main body, resulting in allowing gas to flow to a burner 43 in order to ignite. The water 35 in the metal pipe 41 turns into steam 44, while passes through the metal pipe 14 and enters the pressure chamber 70 of the switch gear so that both the switching cylinders 64 and 60 are pushed up and in this case, in spite of the cylinder hole 77 of the switching cylinder 64 being brought to fail to coincide with the gas hole 63, the cylinder hole 78 of the switching cylinder 60 coincides with the gas hole 59 of the main body, resulting in continuing to flow gas to the burner 43. If flame 39 goes out on some cause of other during the burning operation, the pressure in the pressure chamber 70 lowers so as to allow the switching cylinder 60 to be pushed down by a spring 58 and consequently, the shutting-off of gas flow is resulted.

Title: Control method for articulated truck
Inventor: SAIMA TORU
IPC: B60L15/32
Filed: 1994-02-22
Abstract: PURPOSE:To allow decision making of how each motor shaft must be controlled by controlling the driving power differently for the front and rear shafts of an articulated trucks thereby verifying the axle load distribution in the train. CONSTITUTION:In case of a train of five carriages including vehicles 1, 3 at the opposite ends having no motor and provided with four articulated trucks, the total driving power is assumed equal to the total resistor elements and the shift of axle load between trucks is determined for each vehicle based on the dynamic balance thereof. Variation in the bolster spring load acting on each truck from each vehicle is then calculated and added to the shift of axle load thus determining the shift of axle load for the entire train. The shift of axle load is then calculated for each shaft including each articulated truck and added to or subtracted from the axle load of each shaft thus determining an actual axle load for each shaft. Consequently, it is ascertained that the articulated truck part does not produce any axle load shift between the trucks but produces an axle load shift only within the truck and a decision can be made how each motor shaft must be controlled.
