Title: Protection cylinder for molten body dipping tool
Inventor: SUZUKI TAKASHI
IPC: G01N1/10
Filed: 1987-05-23
Abstract: PURPOSE:To simplify a manufacture process for a protection cylinder by sintering sintered inorganic particles of a sintered sheet wound around a tube body made of an organic body at the high temperature of a molten body to be dipped and constituting a sintered layer which has heat insulation and strength. CONSTITUTION:When the protection cylinder 1 which is not dipped is dipped in the molten body, a flux layer 3 between on the outer periphery of a sintered sheet layer 2 and nearby the outermost layer part of the sintered sheet layer 2 and the outer layer part of the layer 2 which adjoins to it are heated up to high temperature, the layer 3 is fused to become a glass layer 11 with high viscosity, and sintered organic particles of the sintered sheet are sintered to form the sintered layer 12. The sintered inorganic particles are fused partially depending upon the material and united with the glass layer 11. The layer 11 on the surface prevents the layer 12 from being peeled off and the layer 12 forms a heat insulating layer with the unsintered layer 2 to prevent heat from being conducted rapidly to the inside tube body 4 made of the organic body. Further, the sintered sheet is porous, so it never cracks even when heated abruptly.

Title: Hydraulic machine runner touching accident preventing system
Inventor: MORIGUCHI KAZUO
IPC: F03B15/18
Filed: 1978-10-16
Abstract: PURPOSE: To prevent runner from its touching with stationary part and to thereby improve its efficiency by disposing automatic shut-off valve on main supply line which directs pressure water from its source to each feed line of static pressure pockets, and also by disposing throttle valve on each of the feed lines.  
     CONSTITUTION: An automatic shut-off valve 27 is disposed on main feed line 21 which directs pressure water frow its source 25 to each feed line 21 of static pressure pockets 20 formed in a stationary part confronting runner 3. The shut-off valve 27 is opened only at times of starting, low load, closed pump, and shut-off load when radial vibrating action against runner 3 is increased, so that pressure water from its source 25 is supplied to static pressure pockets 20 for preventing wasteful discharge of pressure water. Moreover, since throttle valve 28 has been disposed on each feed line 26, a force which may eliminate vibrating action is generated so that even if clearance between rotating part and stationary part is narrowed, touching of rotating part with stationary part is prevented, rfesulting in leakage loss reduced and efficiency increased.

Title: Centrifugal sirocco fan
Inventor: SAEKI TAKAFUMI
IPC: F04D29/30
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To realize a centrifugal sirocco fan low in noise and displaying excellent blower performance by preventing a negative pressure area from being formed at the inner diameter side half part of the rear side face of each blade. SOLUTION: Through holes 7, 7 communicating front side faces 4 and rear side faces 5 of blades 2, 2 are formed in the inner diameter side parts of the blades 2, 2. The width dimension of the through holes 7, 7 are to be 1/5 or less of the width dimension of air passages 3, 3 in the through hole provided parts.

IPC: F16C19/52
Filed: 1978-10-17
Abstract: PURPOSE: To obtain a unit which can find an abnormal part without reference to a rotational frequency, by detecting the cycle of an abnormal value by extracting a fundamental wave of abnormal vibration and then by counting the number of pulses of a shaft encoder which generates pulses corresponding to the rotation angle of a shaft between fundamental waves.

Vibration converted into an electric signal has its low-level signal cut by noise filter 1 and is waveform-shaped by differentiating circuit 2 to obtain a gate signal for counter 3. Counter 3, supplied with pulses from shaft encoder PG connected to the shaft of motor M, sends pulses to digital comparators 4 and 5. In digital comparators 4 and 5, model signals have already been set which correspond to an abnormal part, and pulses are compared with them to know the occurrence of a damage to the bearing and whether the part is at an internal wheel or external wheel.

Title: Energy generator utilizing oil pressure
Inventor: FUKUMOTO SHIGEO
IPC: F03G7/00
Filed: 1986-05-30
Abstract: PURPOSE:To enable discharge of pressure oil by applying shrinking force by oil pressure onto two points such that the force being applied onto one point slides over a circular arc while the other moves over a plane. CONSTITUTION:Point C of a rack 1 of a displaceable board engages at two points of a fixed circular arc 2 while the portion L of a L-type shrinkable rod 3 LM is contacting at the point C of an arc of the displaceable board. When pressure oil is injected into an oil tube 5 of the L-type shrinkable rod 3, a shrinking force junctions between two points in L section and K section of the L-type shrinkable rod 3. The force being applied onto the L section is supported at the point C of the displaceable board arc while the force being applied onto the K section is supported by oil pressue generating in the oil tube 10. Since the oil discharge port of the oil tube 10 is choked under this condition, the force is balanced at two points but when the oil discharge port is opened, the pressure in the oil tube 10 is removed thereby the oil can be discharged.
