Title: Steam temperature reducer
Inventor: MARUTA TOMONORI
IPC: F22G5/12
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To reduce the temperature of superheated steam uniformly by fixing vanes for swirling steam flowing downward to the inside of an ejector in a steam pipeline and providing a cooling fluid injecting part on the inlet or outlet side of the revolving vane. SOLUTION: An ejector 4 disposed in a steam pipeline 3 having an inlet 1 and an outlet 2 is provided internally with revolving vanes 5 and provided with a cooling fluid injecting part 6. The revolving vane 5 is simply required to impart steam flowing downward from the inlet 1 with a swirl. For example, a vane revolving like an impeller or a fixed revolving vane may be employed. Steam flow is throttled through a nozzle 9 to increase the speed and sucks cooling fluid from a cooling fluid injecting section 6 in a suction chamber 10 and then pressure is recovered at a diffuser section 11. Consequently, mixing of steam and cooling fluid is accelerated and the mixture is supplied to a specified position from the outlet 2.  According to the structure, the cooling fluid is mixed with steam while being dispersed uniformly over the entire steam and the temperature of steam can be reduced uniformly.

Title: Gas insulation static induction equipment
Inventor: IGA TAKASHI
IPC: H01F27/32
Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a static induction equipment whose coil occupancy rate is large, whose coil serial electrostatic capacity is large, and whose insulation reliability on an impact voltage is excellent. SOLUTION: A disc coil 3 is constituted by winding a shield wire 2 by using a rectangular transition cable 1 whose cross-section is molded in an almost rectangular shape by packing flexible insulated materials 6 in recessed parts formed by displacing rectangular wires 4. Then, the plastic insulated materials 6 are thermohardened in a drying process after the coil is wound up. Thus, an electrostatic capacity between a transition cable 1 and the shield wire 2 and between the adjacent transition cables 1 can be increased. Even when the winding length of the shield wire is short, the serial electrostatic capacity of the whole coil can be increased. Therefore, it is possible to provide a static induction equipment whose coil occupancy rate is made high, and whose insulation reliability on an impact voltage is made excellent.

Title: Body-speed estimating apparatus for four-wheel driving vehicle
Inventor: ITO YOSHIHITO
IPC: B60T8/58
Filed: 1991-11-15
Abstract: PURPOSE:To estimate the speed of a body adequately even if an error occurs in the detection of the actual acceleration and a driver does not ease an accelerator in slipping. CONSTITUTION:An acceleration VBF corresponding to a wheel speed is compared with an actual accleration GX, and whether the wheel starts slipping or not is judged with a slip-starting judging means 216f. When the wheel starts slipping, the values with respect to the actual acceleration GX are integrated with time based on a body speed VBo corresponding to the wheel speed obtained at this time and the actual acceleration GX. The obtained value is added to the body speed VBo corresponding to the wheel speed, and the body speed is computed. This body speed is made to be the estimated body speed VB with a body-speed estimating means 216g corresponding to the actual acceleration. The body-speed estimating means 216g corresponding to the actual acceleration is set so that the value with respect to the actual acceleration GX is changed with the elapse of time.

Inventor: WATASE KOTARO
IPC: G01C19/56
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To obtain a vibrating gyro in which the vibrating amplitude of a vibrating body is made large and which prevents the damage of a support part by making the thickness in the length direction and that in a direction at a right angle to the length direction of the support part equal to each other and making the thickness in the up-and-down direction of an intermediate part thin. SOLUTION: In a sensor chip 1, a semiconductor substrate is etched and worked anisotropically, a vibrating body 2, a frame part 3 and support parts 4 are constituted integrally, and a piezoelectric element 5 for drive is vapor-deposited and formed in the central part on the surface of the vibrating body 2. At this time, every support part 4 is constituted in such a way that its thickness in the length direction and in a direction at a right angle to the length direction is made equal to each other and that the thickness in the up-and-down direction of an intermediate part excluding a coupling part with reference to the vibrating body 2 and the frame part 3 is made extremely thin. Thereby, the vibrating amplitude in the Z-direction of the vibrating body 2 and that in the Y-axis direction in which the Coriolis force is generated can be made large.  In addition, an upper lid and a lower lid in which recessed part is formed in a depth suppressing the displacement of support part 4 are bonded to the chip 1. Thereby, even when an excessive mechanical stress is applied to the vibrating body 2, it is possible to prevent the damage of support part 4 without disturbing its vibration largely.
