IPC: F23C10/18
Filed: 1994-04-25
Abstract: PURPOSE:To restrict wearing of a heat exchanging tube installed in a fluidized bed by a method wherein a bed material struck against the heat exchanging tube installed within the fluidized bed is comprised of fine particles in which ceramic materials such as alumina or the like are formed into a substantial spherical shape. CONSTITUTION:As particles 2 acting as bed material, various kinds of fine particles in which material of ceramic system such as gamma-alumina balls, hot-blast furnace slags, water-crushed slags, conical sands and actual device applied PFBC bed material and the like are formed into a substantial-sphere shape under an operation of a high temperature gas blast erosion device 1. These particles 2 are struck against a test piece 3 made of a carbon steel which is similar to an inner structural member in a fluidized bed of a heat exchanging tube or a furnace wall arranged in the fluidized bed, resulting in that wear generated at the test piece 3 is measured. It is possible to restrict wearing of the heat exchanging tube or the furnace wall and the like through this measurement due to the fact that the shape of the particle is sphere.

Title: Method for rigid tube lining on inner surface of tube including bent part
Inventor: MIYAZAKI YASUO
IPC: F16L9/18
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To prevent lining folds from occurring by a method wherein in formation of a rigid tube lining, a tube is continuously heated and pressurized, drawn to be elongated by a specific size, pressure force is raised elongating the tube to be expanded, the tube is released from traction, heated and pressurized, and expanded to be bonded to an inner surface of the tube. SOLUTION: After inserting a deformingly worked rigid tube 2 into a tube 1 including a bent part 1a, steam is supplied from a supply line 3 and expanded. At this time the tube 1 is elongated axially by 100% or under of tube aperture in elongation degree per one position of the bent part 1a with a traction means 5. A fold 4 comes thus inclined to be elongated. Then, pressurizing force of the steam is raised continuing tractive operation, and the steam is expanded. At this time the fold 4 can be almost thoroughly eliminated with elongation and expansion. The elongation degree in this process is made 100% or under of tube aperture per position of the bent part 1a in the same way. Lastly traction of the tube 2 is stopped, expansion by pressurizing with steam is continued, and the tube 2 is boned to an inner surface of the tube 1.

Title: Oldham's coupling
Inventor: MOCHIZUKI MASANORI
IPC: F16D3/04
Filed: 1987-04-08
Abstract: PURPOSE:To enlarge the transmitting torque, by integrally connecting opposed walls having grooves by a connecting member, and preventing a distance between both the opposed walls from expanding by the connecting member. CONSTITUTION:An outer peripheral wall of an intermediate member 3 outside a bore portion 53 functions as a connecting member 5. A distance between inner peripheral walls of the connecting member 5, that is, a length between ends of the bore portions 53 is greater than a projecting length of projections 41 and 42. Accordingly, a wall portion between the bore portions 53 is partially pressed by the ends of the projections 41 and 42 upon transmission of a torque, thereby hindering the distance between opposed wall surfaces formed with grooves 51 and 52 from expanding. As a result, the torque to be transmitted is enlarged.

The theoretical estimated yaw angle is operated from the estimated yaw angle, yaw rate (r), car velocity V and radius of curvature R of road of respective last values. Based on the deviation between the real lateral position and the estimated lateral position when the magnetic nail 3 is detected, the feedback correction of the estimated lateral position and estimated yaw angle is performed. After the feedback correction, the estimated values are used as the last values for operating the estimated lateral position and the estimated yaw angle.

Title: Ignition device for engine
Inventor: KURANO YOSHIAKI
IPC: F02P11/04
Filed: 1991-04-18
Abstract: PURPOSE:To disable an engine from starting, in the case of conducting a power supply circuit by improper action of performing no on-operation of a main switch, by inhibiting ignition action of a coil driving circuit by a control means only without applying power supply voltage to a detecting circuit connected to the main switch. CONSTITUTION:When a main switch 6 is closed, a current flows in a coil driving circuit 8 from a battery 1 and in a primary coil 3a of an ignition coil 3. Simultaneously, reference voltage of the battery 1 is applied to a detecting circuit 16 through the main switch 6. Then, a driving control signal is fed out to a coil driving circuit 8 from a central arithmetic processing unit to cut off the current flowing in the primary coil 3a, so that high voltage is generated in a secondary coil 3b to start an engine by actuating a spark plug 4. On the other hand, when a power supply circuit 5 is conducted by improper action without closing the main switch 6, no reference voltage is applied to the detecting circuit 16. Consequently, the above-mentioned driving control signal is stopped fed out.

IPC: H01L31/0232
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To obtain an optical signal transmission and reception module which is smaller in the number of parts, is small in size and low in cost by installing a light emitting element on the extension of an optical route of an optical medium for bidirectionally propagating signal light and disposing a light receiving element on the base line connecting the optical medium route and the light emitting element so as to approach the base line with the side face. SOLUTION: A laser 70 is arranged on the forward axial line of the end face 63 of an optical fiber 62. A photodiode 64 is installed laterally in mid-way of the line (base line) connecting the centers of the laser 70 and the optical fiber 62. The photodiode 64 is disposed in the position where its side end 66 is in proximity to the axial line (base line) between the laser fibers. The light emitted from the laser 70 spreads spatially and the light 72 advancing along the base line falls onto the optical fiber end face 63 and is made incident on the optical fiber 62. Rays 73, 74 advancing upward and downward are wasted. On the other hand, the beams 67 to 68 which are emitted from the optical fiber 62 and head slightly downward out of the base line in the signal reception light enters the photodetecting surface 65 of the photodiode 64 and forms the signals effective for signal reception.
