Title: Starting control device
Inventor: YOSHIDA MAKOTO
IPC: F16D43/00
Filed: 1986-03-13
Abstract: PURPOSE:To enable an emergency starting even at the time of failure in the electric system to be performed smoothly enough to bear comparison with those performed at the time of normal operation by providing a starting control device with a normally-open solenoid valve which controls the hydraulic pressure supplied to a starting clutch according to a control signal from an electronic circuit. CONSTITUTION:A solenoid valve 26 controls the output hydraulic pressure according to a control signal from an electronic circuit 34. When the output hydraulic pressure is raised, the engaging torque between clutch plates 4, 5 is always brought in equilibrium with a load of whichever is lower between the output hydraulic pressure and the sum of centrifugal load and a spring tension, and accordingly, a smooth starting can be performed. If by any chance an electrical failure occurs in the solenoid valve 26, its controlling of the hydraulic pressure to a hydraulic pressure chamber 8 becomes impossible, while, the solenoid valve 26 is of a nomally-open type, and therefore, a line pressure PL is introduced into the hydraulic pressure chamber 8 as usual. In addition, as an input number of revolution increases under these conditions, the hydraulic pressure in the hydraulic pressure chamber 8 rises to cause the clutch plates 4, 5 to be engaged with each other, and accordingly, a smooth starting enough to bear comparison with the starting at the time of electronic control can be realized.

Title: Boiling water reactor and its startup method
Inventor: HIDAKA MASATAKA
IPC: G21D3/00
Filed: 1992-03-13
Abstract: PURPOSE:To prevent the flow fluctuation and the lowering of the core stability due to the generation of instability phenomenon in low temperature two-phase flow during a startup of a boiling water reactor, enable a stable reactor startup, shorten the reactor startup time and improve the economy and reliability. CONSTITUTION:By filling primary coolant in a reactor at the startup, pressurizing the pressure vessel 1 with a pressurizing tank 17 and withdrawing control rods 3, the coolant is heated to high temperature at single-phase flow state. Then, by relieving the pressurization so that the pressure in the pressure vessel 1 is approached to the saturation pressure of the coolant temperature, the coolant is moved to two-phase flow state. Then the coolant is heated by nuclear heat in two-phase flow state and a specified reactor operation temperature and pressure are attained. By this, the flow fluctuation and the lowering of core stability due to the generation of instability phenomenon of low temperature two-phase flow during a reactor startup are prevented, a stable reactor startup is enabled, a reactor startup time is shortened and the economy and reliability are improved.

Title: Synthetic resin bottle
Inventor: HAGA TOMOYUKI
IPC: B29C70/00
Filed: 1989-03-09
Abstract: PURPOSE:To effectively prevent the deformation of a bottle by forming it in the wall thickness ratio of a first and a second face thereof amounting to at least a predetermined value in order to provide sufficient wall thickness to the bottle to prevent its plastic deformation due to the residual formation strain. CONSTITUTION:The wall thickness t2 of a second face 3 of a bottle is made larger than that of the conventional bottle, preferably in a ratio of the wall thickness t2 of the second face 3 to the wall thickness t1 of a first face 2 amounting to not less than 0.75. The wall thickness t2 larger than the t1 controls an inward shrinkage of the second face 3 and, at the same time, brings about a reinforcing effect in the transverse direction of the bottle 1 to prevent an outward expansion of the first face 2, resulting in a considerable reduction in the bottle deformation. If the t2 to t1 ratio is less than 0.75, the width A of the second face 3 becomes not less than 2.0% in deformation rate, leading to an undesirably large deformation.
