Title: Device for estimating bias error of sensor
Inventor: KIMOTO EIJI
IPC: G01S3/781
Filed: 1991-10-14
Abstract: PURPOSE:To estimate the bias errors of two sensors because when (k) target positions are observed using the two sensors, each of the sensors has bias error. CONSTITUTION:An observation matrix generator 7 is provided for generating an observation matrix from target observation positions, the positions of sensors relative to each other, and bias error initial values, and an estimated value evaluator 8 for finding the covariance matrix of bias error estimated values and an estimated value calculator 11 for calculating estimated values are provided to estimate the bias errors of the sensors. Since the bias errors are estimated in such a way as to find the solution of an equation in which the bias errors of the sensors are state variables, the errors of various sensors can be obtained simultaneously.

Title: Waste water cleaning method by electrolytic treatment
Inventor: KANAI MASAKUNI
IPC: C02F1/463
Filed: 1990-10-02
Abstract: PURPOSE:To remove heavy metals that can not be removed by a conventional method by mixing and stirring calcium fluoride with waste water to be treated and carrying out electrolytic treatment while leading the mixture to a channel between both tilted electrodes. CONSTITUTION:In an electrolytic bath 7, a DC power source is connected with both tilted cathode and anode plates 9, 10 and electrolytic treatment is carried out. Consequently, electrode reaction is carried out in the electrolytic bath 7. At that time, calcium fluoride is ionized, combined with organic substances and heavy metals to form fluorides which are stable and insoluble in either of acid and alkali. Meanwhile, since aluminum plates are used for both electrodes, fine hydrogen gas bubbles are generated from the cathode plate 10 and aluminum ions are dissolved from the anode 9. Owing to the function of the aluminum ions, which are a electrode reaction product, precipitating suspended matters are flocculated and further hydrogen gas, which is another electrode reaction product, is stuck to the flocculated matters. As a result, suspended matters come up as small flocks having extremely low apparant specific gravity.

Title: Method and device for coating threaded part of pipe
Inventor: TOOMASU II HORUSUTAIN
IPC: B05B5/047
Filed: 1989-10-13
Abstract: PURPOSE: To prevent excess spraying and to eliminate the need for cleaning a threaded section adjacent to a coated threaded section by making a gaseous stream act as a mask to prevent the contact of pneumatrically transported powder with the second part of a pipe and forming a distinct boundary line with the first threaded end subjected to powder coating. CONSTITUTION: While the powder is sprayed from a main nozzle 20 and an auxiliary nozzle 42, high-pressure air is discharged from nozzles 66, 68 toward the threaded section 82 directly adjacent to the endmost part 14 of the pipe 16. These air streams substantially function as the mask to prevent the contact and deposition of the excess spray powder with and to the surface of the threaded section 82 adjacent to the endmost threaded section 14 of the pipe 16. The deposition of the powder on the threaded section 82 adjacent to the surface of the coating part 14 of the pipe 16 is averted in such a manner, by which the sufficient electrical contact is assured between the non-coated threaded section 82 of the pipe 16 and a pipe joint for serially connecting the two pipes.

Title: Ultrasonic motor
Inventor: KAWAI YASUAKI
IPC: H02N2/00
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To obtain an ultrasonic motor whose operation is easy, in which the vibration amplitude of traveling waves generated in a stator is expanded and in which a rotor is turned with high efficiency by a method wherein a groove which is passed through in the thickness direction of a support member is formed in the radial direction of the support member and an elastic piece is installed. SOLUTION: The amplitude of the bending vibration of piezoelectric elements 14a, 14b is expanded by an elastic body 15 and by vibration parts 18a, 18b. Due to the vibration, traveling waves in one direction are generated in elastic pieces 31 in the vibration parts 18a, 18b. The traveling waves are transmitted to the pressure contact face of a rotor. As a result, the rotor is turned, via a frictional force, to a direction opposite to that of the traveling waves in one direction. The elastic pieces 31 which are formed in the vibration parts 18a, 18b on support plates 13a, 13b are formed of grooves 30. The grooves 30 can be formed easily by a punching operation such as a press working operation or the like.  That is to say, since the groove 30 which are formed in the vibration parts 18a, 18b are formed at a time by the press working operation, the support plates 13a, 13b in which the elastic pieces 31 are formed by the grooves 30 can be manufactured in several minutes.
