Title: Inchworm stage
Inventor: NAGAOKA HIDEKI
IPC: G12B5/00
Filed: 1993-03-11

Patent JP-H0755516-A (JP)
Title: Flow meter for air flow measurement
Inventor: HIRU RARIN
IPC: G01F3/16
Filed: 1994-03-22
Abstract: PURPOSE: To minimize an accelerating force produced by friction during initial inflow and by the change of direction of a piston at the dead center of the piston stroke by providing a pressure release control assembly for the control of raising and lowering the piston, a string, a sphere, and a spring in particular. CONSTITUTION: A piston 14 reciprocatingly moves starting from near the lower end 16 up to the upper end 24 of a flow tube by the action of a pressure release assembly 90. When the piston 14 strikes the bottom, a string 116 is pulled to return the piston to its original position. This function overcomes initial inflow friction. The function works during acceleration of the piston 14, and shows a constant speed while the piston 14 is rising. Once the constant speed is reached, losses are associated only with the mass and diameter of the piston 14. Changing the direction of the piston 14 and raising it without external support (not using an external pump) are achieved by changing the relative positions of a sphere 117 and the free end 145 of a spring 120.  Since the upward stroke cycle is started by accurate adjustment of the position of the sphere 17, the piston 14 is hardly accelerated.

Title: Directional wave receiver
Inventor: OOKUBO TSUYOSHI
IPC: H04R17/00
Filed: 1979-04-26
Abstract: PURPOSE:To realize a high-sensitive and stable-characteristic directional wave receiver by arranging plural vibrometers, where internal materials are supported in the housing by two diaphragms where piezoelectric elements are stuck, in a case in orthogonal directions. CONSTITUTION:Sound receiving of case 6 is the pressure gradient type; and since case 6 is operated in the mass control region by suspended rubber 5, response of the vibration speed for the acoustic pressure is fixed in the used frequency band. Meanwhile, the vibration system is formed in vibrometer 7 by mass of internal material 13 and the spring constant of diaphragms 9 and 10, and response of pressure change of diaphragms 9 and 10 for the speed of housing 8 indicates the phase characteristic having a gradient of +6dB/octave and -6dB/octave for frequency f0 peculiar to the vibration system or less and frequency f0 or more respectively. However, output voltage response of piezeelectric elements 11 and 12 for diaphragms 9 and 10 is independent of the frequency, and therefore, the phase characteristic above is response of the directional wave receiver.

Title: High temperature duct guide vane
Inventor: MASE MASATAKA
IPC: F23J11/00
Filed: 1995-03-10
Abstract: PURPOSE: To prevent the vibration of guide vanes and avoid troubles of cracks and the like without generating thermal stress by providing pipe posts fixed to a surface opposed to the inner periphery of a high temperature duct, while both ends in the upstream and downstream sides of guide vane main bodies are held in slits, and providing a plurality of holes on the cylindrical surfaces of the pipe posts. CONSTITUTION: When a high temperature gas flow 3 comes to the bending part of a duct 2 from an upstream part, the direction of the flow 3 changes smoothly leftward by two guide vanes. At that time, even the high temperature gas flow 3 suddenly comes into contact with the guide vanes, guide vane main bodies 1 produce free elongation and do not produce elastic elongation relative to heat, since the guide vane main bodies 1 have their upstream and downstream end edges held through upper and lower groove shaped guide vane bearers 10 relative duct 2 so as to finely slide in a planar direction by pipe posts 4. Further, the guide vane main bodies 1 similarly freely elongate relative to the momentum of the gas flow 3 without storing elastic energy. Thus, vibration is hardly generated without large restoring energy.

Abstract: PROBLEM TO BE SOLVED: To prevent a reduction in detection performance by eliminating the adhesion of iron powder or the like, and obviate the need for adjusting a gap after bearing integration, by integrating a pulser part and a sensor part in which the gap has been adjusted, into a bearing, and seal the sensor part with a seal member. SOLUTION: An annular member 5 is secured to an outer ring 1 of a pipe member 6. Further, an annular member 8 is secured to an inner ring 2 of a pipe member 9. Furthermore, a portion between the inner and outer rings 2, 1 is sealed by a seal member 11. Then, a pulser part 13 is disposed on the inner peripheral face of the pipe member 6, and a sensor part 14 which includes a detector for detecting a rotation speed is disposed on a side face on the inside of a bearing so as to be opposed to the pulser part 13. Accordingly, the pulser part 13 and the sensor part 14 are placed on the inside of the bearing sealed by the seal member 11, so that iron powder, dust, muddy water or the like from outside will not adhere.  Further, the pulser part 13 and the detector of the sensor part 14 are opposing each other in the radius direction, so that there is no need to adjust a gap between the pulser part 13 and the sensor part 14.
