Abstract: PURPOSE:To offset generated thrust and reduce mechanical loss by fixing two turbine blades whose generating quantity is nearly equal, on one shaft, being faced against each other, and branching an exhaust gas into casings having each turbine blade. CONSTITUTION:Turbine blades 2A, 2B whose outputs are nearly equal, are provided, being faced against each other, on both sides of a shaft 3 on which a power recovering gear mechanism 4 is fixed, and housed in casings 6A, 6B respectively.

Title: Liquid crystal optical shutter
Inventor: OOTA MORIO
IPC: G02F1/1343
Filed: 1984-04-29
Abstract: PURPOSE:To operate the liquid crystal optical shutter stably which is used for an optical printer by making the self-heating of the common electrodes of the liquid crystal optical shutter uniform so that the resistance value of the common electrodes to unit length is different between the end parts and center part. CONSTITUTION:The two common electrodes 23a and 23b of the liquid crystal optical shutter 6 are so shaped that the width of the common electrodes 23a and 23b is larger than those of end parts 29a and 29b. Thus, the center parts 28 of the common electrodes 23a and 23b are narrow and become wider toward the end parts 29a, so currents per unit area which flow to the common electrodes 23a and 23b become uniform. Consequently, the self-heating distribution by the operation of a microshutter 10 is made uniform and a heater used for the liquid crystal optical shutter is controlled to proper temperatures to allow the entire liquid crystal to operate under uniform conditions.

Abstract: PURPOSE:To implement the analysis with a high accuracy and a high reproducibility by discarding the reagent alone which has been retained in a distribution nozzle over a specified period without being reserved cold. CONSTITUTION:Time (t) is set for all of reagents by a means 11 and additionally, however the automatic analyzer may operate, distributors 1 and 1' are marked by a means 12 for the reagents which have reached the time (t) within distribution nozzles 7 and 7'.

Abstract: PURPOSE:To shorten the combustion period and to improve the thermal efficiency by providing a needle valve control piston at the atmospheric side while providing a restrictor between an end-of-injection control valve and a high pressure fuel path. CONSTITUTION:As the time elapses, fuel above a needle valve control piston 11 will pass through a path 16 and a restrictor 13 and flow into a high pressure fuel path 14 which has been brought to low pressure. The pressure above said piston 11 will drop continuously and the needle valve control piston 11 is pushed up by a needle valve 20 to increase the lift of needle valve gradually thus to continue fuel injection while increasing the injection rate. The pressure of fuel accumulated in an accumulation chamber 17 will drop continuously as the fuel injection proceeds and finally the end-of-injection control valve 5 is pushed down by a spring 8 and closed. Consequently fuel in said chamber 17 will flow through the path 18, valve 5 and a path to the upper portion of said piston 11 to bring the pressure same with that in said chamber 17.

IPC: F16J15/12
Filed: 1995-04-13
Abstract: PURPOSE: To enhance collapse resistance of an anticorrosive ring by incorporating a metallic reinforcing strip into the inside or the outer periphery of an anticorrosive resin ring to prevent infiltration of a corrosive fluid from an impactively contacting part of a pin tip box central part at joint fitting time. CONSTITUTION: An anticorrosive resin ring 7 is inserted to hold sealing performance of a place where a male screw pin 2 of a joint and a female screw box impactively contact with each other to completely coat an inside surface of an oil well pipe. A steel wire 9 being a metallic reinforcing strip is incorporated into the inside or the outer periphery of this anticorrosive resin ring 7. Therefore, at using time, collapse resistance of the anticorrosive ring 7 can be enhanced to an (n)-ring phenomenon of pushing out the anticorrosive ring 7 inside by a difference between a pressure drop in a pipe inside surface and back pressure of the anticorrosive ring 7. Even if large groove bottom pressure is applied to the anticorrosive ring 7, it can be reliably housed in a groove without being permanently deformed.

Abstract: PROBLEM TO BE SOLVED: To enlarge a visual field range by means of simple configuration by providing a waveguide where plural slots which cross with a tube axis are generated by means of a dimension interval being smaller than a half of the in-tube wave length of a usage frequency, a reflection body arranged in a waveguide terminating part in one end of the waveguide and a power feeding means for supplying radio wave from the other end of the waveguide. SOLUTION: A waveguide slot antenna is constituted by generating the plural slots 10a crossing with the tube axis by the dimension interval being smaller than a half of the in-tube frequency of the usage frequency in a square waveguide 10 and by providing the reflection body 11 in the waveguide terminating part of the square waveguide 10. Incident wave which is made incident the square waveguide 10 and reflection wave reflected by the reflection body 11 are respectively generated towards two different directions since an antenna beam direction is inclined in a direction opposite to the propagating one against the longitudinal line of the tube axis by a prescribed angle by the actuation of the slots 10a so that the wide visual field range is secured. As a result, the time of scanning for scanning a desired scanning range is reduced and scanning time is shortened.
