Title: Deformation preventive structure for gland portion of low pressure steam turbine
Inventor: UMAGOE RYUTARO
IPC: F01D25/24
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent vibrations caused by contact of the rotor and stationary side due to thermal deformation of the gland portion by preventing wet steam from flowing into the gland portion. SOLUTION: At a gland portion periphery 2 of a rotor 1, a gland case 3 is provided, introducing steam 22 for seal with maintaining a predetermined pressure. The steam is then flowing out from seal portions 4, 5 for sealing the gland portion periphery 2. Steam 20 flows into the turbine through the central portion, passing a stationary blade 8 and a moving blade 9 of the last stage, rotating a rotor 1, then flowing out to an exhaust chamber 7, when part of wet steam 21a enters an space 10 through a gap 11. Since the rotor 1 is provided with a projection 15 all around, the wet steam 21a is prevented from flowing to the gland portion periphery 2 and flows in a vortex. This vortex repels moisture, thus preventing the gland case 3 and the seal portions 4, 5 from being partially cooled.  As a result, contact of those parts with the rotor 1 is avoided and vibrations due to such contact is prevented.

Title: Coin tester
Inventor: PIITAA REJINARUDO JIYONSON
IPC: G07D5/00
Filed: 1984-07-28
Abstract: @ A coin testing apparatus subjects a coin inserted into a coin entry (1) and rolling down an inclined track (2) to testing at a testing station (3) comprising sensors (4,5,6) which may for example be inductive sensors. If a coin is found to be acceptable an accept signal is generated and this causes gate mechanism (8) to open to permit the coin to access accept path (9), the gate mechanism (8) being normally closed so that unacceptable coins can only access a reject path (10). A post-gate detector (11) in the accept path (9) senses the passage of an accepted coin and serves to close the gate mechanism (8) and also to determine allocation of a customer credit. A pre-gate detector (12) upstream of the gate mechanism (8) has its output logically processed with the accept signal produced when an acceptable coin is tested and/or with the output of the post-gate detector (11).

Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To manufacture products of high quality by radially providing a dispersion corn and a plurality of dispersion ports, and also providing a flow- rate regulating layer-thickness regulating plate. SOLUTION: When a dispersion vessel 1 is filled with objects of specified amount, some of them already reach the upper surface of a transportation tray 3, and a straight forward feeder 4 is driven to provide the transportation tray 3 with vibration, so that the objects advancing toward the tip end of the transportation tray 3, entering an object-reception hopper 6. Since a means for distributing blended food wherein the dispersion vessel 1 positioned at the center of a dispersion supply device is not given vibration, the blended food is transported to the object-reception hopper 6 with no individual objects separated.  In transportation with the vibration from the straight forward feeder 4, since the layer-thickness of objects on the transportation tray 3 is not a small amount, no separation occurs under the vibration, so the objects discharged from distribution ports 1-3 reach the object-reception hopper 6 in a stable manner.

Title: Apparatus for ultrasonic measurement of position
Inventor: ARAI IKUO
IPC: G01S5/30
Filed: 1985-07-16
Abstract: PURPOSE:To enable the continuous measurement of a position and to attain to enhance measuring accuracy and resolving power, by transmitting a continuous ultrasonic wave with definite frequency to receive the same by three receivers and calculating the three-dimensional position coordinates of a transmitter. CONSTITUTION:A continuous ultrasonic wave with predetermined frequency is transmitted from a transmitter 3 moving from a reference position Z0 to a position Z through an oscillator 1 to be received by three receivers 4-6. Relative distance change measuring circuits 7-9 determine relative distance changes r1-r3 of the transmitter 3 and the receivers 4-6 on the basis of the phase change of receiving signals to supply the same to a position operator 11 which, in turn, operates the relative distance of the position Z on the basis of know relative distances R1-R3 and distance changes r1-r3 to the position Z0 to calculate the three- dimensional coordinates (x, y, z) of the position Z. Because the continuous ultrasonic wave with definite frequency is used, an amplifier with a narrow band can be used and external noise is hardly received and the effect of the variation in a receiving level is reduced by measurement based on phase change while information is continuously obtained even with respect to the movement of the transmitter and the continuous measurement of a position is enabled and measuring accuracy and resolving power are enhanced.

In such engagement, the downward surface 12a of groove of the jig body and the upward surface 11a of handle edge are in contact each other with an inclination angle theta to the horizontal surface and a force F is applied because the weight of jig body W is applied. But if a force opposing to the horizontal component Fx is not applied, the handle edge is not disengaged from the groove of body. The larger such inclination angle theta, the more the effect of engagement.
