Abstract: PROBLEM TO BE SOLVED: To enable emission of light without generating heat by the use of a frictional luminescence phenomenon by providing a piezoelectric film held by an electrode film on a substrate, and providing a pressure-responding light emitting layer that emits light when it is applied with pressure. SOLUTION: A piezoelectric light emission element 1 is provided with a substrate 10, an electrode film 11, a piezoelectric film 12, an electrode film 13, a pressure-responding light emission layer 14 and a transparent substrate 15. The substrates 10, 15 are composed of silicon, inorganic oxide, resin or the like. The electrode films 11, 13 are the electrodes to apply a voltage to the piezoelectric film 12 and are formed of platinum, iridium or the like. The layer 14 is composed of a material that emits light with the reception of pressure with the frictional luminescence phenomenon generated, and in the case of N-isopropyl carbazole used, a strong blue light is generated.  With this constitution wherein no optical source of optical heat is used, a temperature rise is less, and with the detection of intensity of emission of light, deviation of a piezoelectric body can be measured indirectly.

IPC: G01B21/30
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To judge and evaluate the material hardness of an object, to be measured, precisely on the basis of the magnitude of the difference in the height direction between respective curves of a cross section by a method wherein a probe is brought into sliding contact with the surface of the object to be measured, it is moved so as to be overlapped and, whenever it is passed, the outline of the cross section is detected as the surve of the cross section. SOLUTION: A cross-sectional-shape detector 5 detects the shape of the outline 3 of a cross section 2 whenever a probe 4 is passed in such a way that a tip contact part which is mounted on, and attached to, the tip of the probe 4 and which is composed of a rigid material such as a diamond or the like is brought into sliding contact with the surface of an object to be measured and that the tip contact part is moved so as to be overlapped. On the basis of a detection signal from the detector 5, a cross-sectional-curve reading device 6 reads out the shape of the outline 3 in the form of the curve of the cross section whenever the probe 4 is passed, and it sends the shape to a difference computing device 7 as a height signal indicating the height direction from a reference line.  The computing device 7 computes the difference between the curve of the cross section after the previous passage of the probe 4 and that after its recent passage whenever the probe 4 is passed, and it sends a difference signal to a material-hardness judgment device 10. Out of evaluation patterns which are stored 9, the judgment device 10 selects an evaluation pattern to which the difference signal conforms, and it displays 11 the evaluation pattern visually.

IPC: F16F9/32
Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To miniaturize pistons while securing sealing performance between the mutual pistons in a two piston type. SOLUTION: A piston part 20 is composed of a lower piston 28 and an upper piston 56. The upper piston 56 is pressed in a recessed part 30 of the lower piston 28.

IPC: F04D29/18
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent any increase in driving force even if a gap narrowing member is brought into slide-contact with the inner face of a suction casing and prevent any clogging of foreign matters in liquid in a gap by fixing the gap narrowing member made of a flexible material to the tip of a blade rotated in the vicinity of the inner face of a casing or a casing liner. SOLUTION: A gap narrowing member 20 for narrowing a gap between the tip of a blade 3 of an impeller 1, i.e., a portion which is rotated in the vicinity of the inner face of a suction casing 11 and the inner face of the suction casing 11 is fixed to that portion. The gap narrowing member 20 is made of a flexible material which is low in frictional resistance when it is brought into slide-contact with the inner face of the suction casing 11, is excellent in abrasion resistance and is easily flexible, such as rubber. Consequently, during operation of a mixed flow pump, it is possible to reduce a quantity of liquid leaking at the gap between the gap narrowing member 20 and the inner face of the suction casing 11.  Furthermore, even if the gap narrowing member 20 is brought into slide-contact with the inner face of the suction casing 11, any damage can be prevented because of low friction resistance and sufficient abrasion resistance.
