Title: Method of producing grain oriented silicon steel sheet having excellent magnetic property and coating property
Inventor: TOGE TETSUO
IPC: C22C38/00
Filed: 2001-12-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for improving the magnetic properties of a grain oriented silicon steel sheet after finish annealing by properly controlling the growth of grains in a primarily crystallized sheet even under the condition that a slab heating temperature is low to the extent of the case of common steel, and also improving its coating properties.  <P>SOLUTION: The steel slab having a prescribed componential composition is heated to ≤1,300°C, and is thereafter hot-rolled. After that, the steel sheet is, if required, subjected to hot rolled sheet annealing, and is then subjected to cold rolling for one time or for two or more times including process annealing so as to obtain a final sheet thickness. Next, the steel sheet is subjected to annealing for primary recrystallization and decarburization, and is then subjected to final finish annealing. In this method of producing a silicon steel sheet consisting of a series of stages above, electromagnetic stirring is performed on casting of the steel slab, and, as for the annealing for primary recrystallization and decarburization, the steel sheet is retained in the temperature range of 600 to 1,000°C for ≤120 sec, and also, the atmosphere in the residence period is controlled so that the content of hydrogen is regulated to 30 to 60 vol.%, and a dew point to 15 to 40°C, and, after that, the steel sheet is retained in the temperature range of 750 to 900°C for ≥60 sec, and the atmosphere in the residence time is controlled so that the content of hydrogen is regulated to 40 to 70 vol.%, and a dew point to 40 to 70°C.  <P>COPYRIGHT: (C)2003,JPO

Title: Fluid pressure utilization toy
Inventor: NIKAIDO TERUO
IPC: A63H30/06
Filed: 2001-12-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide an attractive fluid pressure utilization toy.  <P>SOLUTION: The fluid pressure utilization toy has a fluid pressure change detection means that is installed in fluid for detecting change in fluid pressure, and a figure object that changes an operation state by detecting the change in the fluid pressure by the fluid pressure change detection means. 'Operation state change' in this case includes not only transition from one operation state to another but also transition from a non-operation state to the operation state, and also includes the reverse. Achieving the 'operation state change' is made by, for example, setting the motor being a power source to an activation state from a stop state or vise versa, and by changing the engagement of a toothed wheel.  <P>COPYRIGHT: (C)2003,JPO

Title: Fuel cell stack cooling liquid conductivity sensor using differential voltage measurement
Inventor: HORTOP MATTHEW K
IPC: H01M8/04
Filed: 2002-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for detecting leak current in cooling liquid of a fuel cell stack. SOLUTION: Voltmeter is used for measurement of cooling liquid voltage. The lower the cooling liquid voltage is, the larger the leak current is. That is to say, if cooling liquid voltage is below a given level, the cooling liquid is excessively conductive, and leak current is reported. To realize this, cooling liquid voltage measured by the voltmeter is compared (84) with a first given voltage, and a report is made (86) if the cooling liquid voltage is below the first given voltage. Further, the cooling liquid voltage is compared (90) with a second given voltage, and a report is made (92) if the cooling liquid voltage is below it. The second given voltage is higher than the first given voltage.

Title: Method and device for modifying position in vehicle navigation system and heading error
Inventor: GEIER GEORGE J
IPC: G01C19/00
Filed: 2002-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle navigation system for correcting the drift of temperature-dependent bias by a vehicle heading sensor with a dead-reckoning vehicle positioning system. SOLUTION: Especially, a Kalman filter produces a calibration curve of the bias drift rate of the heading sensor corresponding to the variation of the temperature. The Kalman filter calculates a model coefficient of the bias drift rate to the temperature of the heading sensor by point where a vehicle 4 is rested. Next, using the calibration curve of the bias drift rate, the bias of the heading sensor is periodically estimated while the vehicle is moving. Further, the navigation system converges the error dispersing matrix of the Kalman filter by using the aging time of the bias drift rate of the temperature sensor.

Abstract: PROBLEM TO BE SOLVED: To provide a method capable of favorably providing a header with a single or a plurality of flat pipe insertion grooves having a favorable groove outline. SOLUTION: In the method for providing the header with at least one flat pipe insertion groove, a saw-cut is made in the header in a sawing step, and the grooves are formed by a groove punch for punching the saw-cut area in the subsequent punching step. A collar forming hole is formed by using the groove punch having the width and/or length larger than the saw-cut in the punching step. The saw-cut is provided to the depth smaller than the wall thickness of the header. Each belly area between chambers of a multi-chamber header is pressed deeper than the level of the header wall area functioning as a flat pipe insertion stopper during the punching to form a chamber-communicating passage. This method is applicable for an evaporator and a gas cooler of a carbon dioxide air conditioner in a car, etc.

Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical fiber cable which suppresses movement of ribbon cores even under severe environment conditions and makes the ribbon cores hard to draw in or protrude.  <P>SOLUTION: The optical fiber cable having ribbon cores stored in grooves 12 of a grooved rod type member 10 is characterized in that the grooves 12 comprises a unidirectional spiral groove 12a whose spiral pitch is larger than one pitch and an inversion groove 12b which is inverted in spiral direction from the unidirectional spiral groove and whose pitch is less than one pitch which are formed alternately along the length. The ribbon cores are given an extra length for the unidirectional spiral groove 12a in a section where it is stored in the unidirectional spiral groove 12a. The ribbon core is curved in S shape by the inversion groove 12b to restrict the movement along the length.  <P>COPYRIGHT: (C)2003,JPO
