IPC: G01B7/24
Filed: 1990-11-16
Abstract: PURPOSE:To enable distortion of an object to be measured easily and with high sensitivity by mounting an amorphous foil or a thin film of a magnetic metal on a substrate surface at an opposite side of a surface to be mounted on an object to be fixed and then fixing both edges to the substrate. CONSTITUTION:An opposite surface to a round bar 1 of a cylindrical substrate 2 where the round bar 1 with a radius of r1 whose distortion is to be measured, namely an outer-periphery surface of the substrate 2, is surrounded by a sensor element thin film 2 with an outer-periphery radius of r2. Both edges of a thin film 3 are held between a coating thickness part of both edges of the substrate 2 and fixing metals 4, 4' and is fixed by welding 5, 5' metallurgically or mechanically. Then, when using, this unit is welded and brazed to the round bar 1 for joining metallurgically and fitting. At this time, if the round bar 1 is a metal which is subjected to heating treatment, heating treatment state is changed, fixing is performed by a method without any thermal influence by designing elements such as a type or materials to be used, measuring conditions, conditions of use of the round bar 1 to be measured as a stress transmission member, thus preventing thermal influence from being added to the thin film 2 for deteriorating magnetic characteristics and a highly accurate measurement from being disabled.

Title: Motor controller
Inventor: OKAZAWA KAZUHIKO
IPC: H02P8/00
Filed: 1992-11-18
Abstract: PURPOSE:To allow stopping of a motor at an accurate position while sustaining high speed during steady rotation by changing the drive mode of motor until a load is stopped in response to an output from a sensor. CONSTITUTION:In a system where movement and positioning of a load 1 are carried out using a step motor 6, a sensor 3 recognizes residual movement of the load 1 upto a predetermined stop position and a control circuit 7 changes drive mode of the motor 6 until stoppage of the load 1 in response to an output from the sensor 3. Consequently, slow-down start timing can be recognized accurately by predetermining a steady state speed of the motor 6 and a slow- down amount corresponding thereto. This constitution allows to stop a load 1 having high inertia at an accurate position while sustaining high speed during steady state rotation.

Title: Electric heating assembly and electric heater
Inventor: ROBAATO BUREMUNAA
IPC: H05B3/14
Filed: 1987-12-04
Abstract: A system for automatically disconnecting a conductive polymer heater if an arcing fault occurs. A sensor conductor (4) is incorporated into the heater, so that if an arcing fault occurs, the current through the sensor conductor increases and triggers a safety circuit to disconnect the heater. As illustrated in Figure 1, the sensor conductor is preferably insulated by an organic polymer (5) which pyrolyses if an arcing fault occurs and thus permits current to flow between the sensor conductor and an electrode (1) of the heater.

Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic flow meter capable of forming the magnetic field with the desired magnetic flux distribution without being limited by space by providing a magnetic field generating means, electrodes, and an inner core (made narrower in width at portions near electrodes than at other portions). SOLUTION: A coil 4 is excited to generate the magnetic field in the direction perpendicular to the axis of a measuring tube 1, and electromotive force is generated when a measured fluid is moved in the measuring tube 1 located in the magnetic field. If the magnetic field is generated perpendicularly to the electrically insulated measuring tube 1 and the conductivity of the flowing fluid is not too low, the electromotive force can be measured between a pair of electrodes 5. Noises are removed from the electromotive force, the electromotive force is converted into the signal corresponding to the fluid and outputted by a converter, and the flow can be measured. Since both end sections of an inner core 8 are tapered, the magnetic field can be concentrated at the portions of the electrodes 5, and accurate measurement can be made by the small- diameter electromagnetic flow meter.

Title: Thin film photoelectric conversion element
Inventor: KATO SHINJI
IPC: H01L31/04
Filed: 1994-12-14
Abstract: PURPOSE: To reduce reflectivity of the surface of a thin film photoelectric conversion element to improve the photoelectric conversion factor of the element by interposing a light transmissive insulating film, of which the refractive index continuously changes in the thickness direction between those of a transparent electrode layer and sealing material, between the electrode layer and sealing material on the light incident side.

Title: Production of boiled noodle
Inventor: YASUDA YOICHI
IPC: A23L7/109
Filed: 1989-11-29
Abstract: PURPOSE:To obtain boiled noodle having a good texture in a relatively shortened boiling time by boiling a dough comprising a noodle raw material compounded with oil or fat-processed starch in specific water content. CONSTITUTION:A noodle raw material is compounded with an oil or fat- processed starch and the prepared dough is boiled to a water content of 55-65% to provided the objective boiled noodle. The oil or fat-processed starch is added to the noodle raw material within a suitable range of 5-40% depending to the nature of the starch when the wheat flour and the oil or fat-processed starch are totally 100. When the amount of the compounded oil or fat is <=5% (e.g. 4%), the advantages (e.g. the noodle is rapidly boiled or the boiled noodle is smooth) of the addition of the oil or fat-processed starch are lost, and when >=40%, the texture of the boiled noodle may be damaged. The water content of the boiled noodle is preferably 55-65%, because when the water content exceeds 65%, the boiled noodle is too soft and loses the elasticity and when below 55%, the boiling of the noodle is imperfect to leave a core therein and the texture thereof is instead damaged.
