Title: Piezoelectric sensor
Inventor: ITO CHIKAICHI
IPC: H01L41/08
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain a sensor whose mass productivity is excellent and which is highly sensitive to a shock and an acceleration by a method wherein a piezoelectric element comprises a pair of piezoelectric bodies on both ends in the length direction and one or more elastic members are provided in the central part which contains the center in the length direction of a part sandwiched between the pair of piezoelectric bodies. SOLUTION: A piezoelecteric sensor is a straddle-mounted beam-type piezoelectric sensor in which both ends in the length direction of a piezoelectric element are fixed, and it has a structure in which two piezoelectric bodies 1 polarized in the thickness direction of the piezoelectric element are bonded by an elastic member 2 which is deformed easily. Thereby, the piezoelectric element is deformed easily by a shock and an acceleration as compared with a cantilever-type piezoelectric sensor, and its sensitivity is enhanced. An electromotive force is taken out easily. The mechanical damage of the piezoelectric sensor is not generated in its mechanical machining operation as compared with the cantilever-type piezoelectric sensor.  It is preferable that an electrode 3 and an electrode 4 which are formed on the main surface of the two piezoelectric bodies 1 of the piezoelectric element are connected, e.g. by a conductor of the same material as the electrodes 3, 4 or by a conductor such as an Au conductor, an Ag conductor or the like so as to be kept at an identical potential. In addition, the piezoelectric bodies 1 are formed as piezoelectric bodies 1 of a bimorph structure, and bimorph piezoelectric bodies 1 are used. Thereby, a high output voltage is obtained.

Inventor: AKEDA MASAHIRO
IPC: F02B3/06
Filed: 1986-03-14
Abstract: PURPOSE:To prevent mist from adhesion to the side peripheral wall of a combustion chamber and to prevent production of blue while smoke, by a method wherein nozzle holes are formed in plural spots in the peripheral direction of the suck part of a multi-nozzle hole nozzle, and a spray angle enlarging groove is formed in a particular state. CONSTITUTION:Nozzle holes 3 are formed in plural spots in the peripheral direction of a suck part 2 of a multi-nozzle hole nozzle 1 for injecting fuel of a diesel engine E. A spray angle enlarging groove 6, enlarging the direction of the spray angle of fuel, is formed in an outer peripheral surface 7 of the suck part 2 in a state in that it is extended across an outlet 4 of the nozzle port 3. Since the bore of a combustion chamber 5 can be increased, fuel sprayed through the nozzle 1 is drawn in a swirl throughout a long distance until it approaches the side peripheral wall of the combustion chamber 5, and is diluted. This constitution enables prevention of adhesion of mist to the side peripheral wall of the combustion chamber, and prevention of the production of blue white smoke.

Filed: 1990-03-12
Abstract: PURPOSE:To decrease abrasion of a horn and a receiving tool and to make it possible to perform stable welding and sure cutting by providing a vertical face of the receiving tool which is vertical to a rotational shaft of the receiving tool on an end face of the receiving tool and providing an outer periphery-facing part having a face facing and being close to the outer peripheral face of the receiving tool and a vertical face-facing part having a parallel face which is brought into contact with the vertical face on a tip of the horn. CONSTITUTION:A receiving tool 12 has a vertical face 12b of the receiving tool which is vertical to a rotational shaft of the receiving tool on an end face of the receiving tool and on the other hand, a horn tip 11 has both an outer periphery-facing part 11a having a face which faces and is close to the outer peripheral face 12a of the receiving tool and a vertical face-facing part 11b having a parallel face which faces to and is brought into contact with a vertical face 12b of the receiving tool. Welding of sheets 15a and 15b is produced by heat- generating action caused by ultrasonic vibration applied to the sheets from the outer periphery- facing part 11a and the outer peripheral face 12a of the receiving tool and cutting of the sheets is produced by melting based on heat-generating action caused by vibration applied to the sheets from the vertical face-facing part 11b and the vertical face 12b of the receiving tool. When the sheets are welded, as the outer peripheral face-facing part and the outer peripheral face of the receiving tool are not brought into direct contact with each other, abrasion of these parts remarkably less.

Title: Stator coil in rotating machine
Inventor: SUZUKI YASUKO
IPC: H02K3/40
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a corona-preventive sheet made of conductive sheet in a stator, in which the corona-preventive sheet has conductivity enough to prevent corona discharge, along with no flaking, uneven conductivity or a deterioration in impregnation resin. SOLUTION: Aramid fiber 32 and carbon fiber 31 are mixed in a given ratio and woven into a conductive fiber sheet 3. The fiber sheet 3 has given conductivity in proportion to the containing ratio of the conductive carbon fiber 31. In this case, the carbon fiber 31 hardly comes off, because it tangled with the aramid fiber 32, and thereby constant conductivity can be obtained. By using the aramid fiber 32 that has heat resistance, the corona-proof sheet 3 that meets the heat resisting strength necessary for the stator coil in a rotating machine can be obtained.

Title: Method for controlling thickness in continuous hot rolling mill
Inventor: KOSEKI TOMOHITO
IPC: B21B37/72
Filed: 1992-02-14
Abstract: PURPOSE:To provide a thickness controlling method that good thickness can be attained from the tip of a hot strip. CONSTITUTION:In a continuous hot rolling mill, at least a thickness gage 11 and a thermometer 12 are provided between stands. When the tip of a material 13 to be rolled is bitten into the stand just before the thickness gage 11, rolling force and draft position of the stand are detected.

Title: Process for forming pattern using resin film
Inventor: HORIKAWA YUKIO
IPC: C08G73/00
Filed: 1987-03-13
Abstract: PURPOSE:To improve heat resistance of a pattern by using a polyisoimide resin constituted of recurrent units comprising a specified isoimide structure in at least 80mol.% of the polyisoimide resin, as a photosensitive polymer. CONSTITUTION:In a process for forming an picture image on a resin film utilizing the change of solubility due to a photochemical reaction of a photosensitive polymer, a polyisoimide resin is used as a photosensitive polymer, wherein at least 80mol.% thereof is constituted of recurrent units having an imide structure expressed by the formula I. The polyisoimide resin is produced from a tetracarboxylic acid deriv. and acid anhydride deriv., etc., and a diamine or a diisocyanate as starting materials. Polyisoimides are more easily handled because they have superior solubility as compared to polyimide derivs. having a photosensitive group and are far stabler in the state of solution. Moreover, since the polyisoimide itself is photosensitive requiring no photosensitive group to be introduced, there is almost no fear for decreasing the film thickness nor generation of voids. Thus, the control of the film thickness is executed more easily, and a resin film pattern having high heat resistance is obtd.

IPC: B29C48/35
Filed: 1991-02-28
Abstract: PURPOSE:To enhance not only degree of crystallization but also mechanical properties in a direction specific with respect to a surface area direction by adding a glass fiber to a thin plate made of a crystalline thermoplastic synthetic resin so as to orient the same in the definite surface area direction of the thin plate and molding a molten resin into a plate material to gradually cool the molded one. CONSTITUTION:A crystalline thermoplastic synthetic resin 30 mixed with a glass fiber held to a heated molten state is extruded from the die 2 of an extruder to be accumulated in the front part of the gap between the first stage rolls 41a, 41b of a roll molding machine 4 and passed through the roll gap by rotating the rolls 41a, 41b and the resin being contact with the surfaces of the rolls is rapidly cooled to its crystallization temp. to be solidified. By this method, the solidified layers are formed into plate-shaped surfaces to mold a plate material 3. Subsequently, the plate material 3 is passed through the gap between next stage rolls 42a, 42b to advance cooling from the surface layers of the plate material to the interior thereof to complete the solidification or the plate material 3. At this time, by circulating heated oil to the roll hollow parts 411, 412 of the rolls of the respective stages, the cooling of the resin plate is suppressed and the degree of the crystallization of the synthetic resin is enhanced.
