Title: Method and apparatus for producing metal screen
Inventor: YOHANESU TONISU SUNAAKENBORUFU
IPC: C25D1/08
Filed: 1987-07-06
Abstract: In a method for forming a sieve material a base sieve material is connected as a cathode in an electroplating bath; said bath contains an amount of a compound having properties of a second class brightener and during electrodeposition a flow of liquid is maintained through the perforations of the base sieve material. A thin deposit is allowed to form; said deposit is removed from the base sieve and thickened under essentially the same conditions in a further electroplating step. The thickened deposit has perforations of essentially the same size as the perforations in the base sieve material. The method may be carried out continuously. The invention concerns also a device for carrying out the method according to the invention.

IPC: B65F3/00
Filed: 1993-06-15
Abstract: PURPOSE:To provide a control device for an automatic cleaner having no uncleaned portion and causing no trouble to clean the same path again by providing a mop wiping the floor surface separately from a suction port. CONSTITUTION:A frame sucks the refuse on the floor surface from a suction port while being traveled, and it wipes and cleans the floor surface with a mop member located behind the suction port. When the frame reaches the end of a prescribed cleaning area or an obstacle is detected in the advance direction during this cleaning, the travel is stopped, and the frame is retreated by a prescribed distance for the next process. The refuse not sucked into the suction port is thrust forward by the mop member, however the suction port passes on the refuse when the frame is retreated, and the refuse is sucked.

Title: Catalyst combustion burner
Inventor: NAKANO HAJIME
IPC: F23D14/18
Filed: 1988-07-07
Abstract: PURPOSE:To make it possible to obtain concentrated catalyst combustion effect, improve strength and compact its size by constituting a catalyst which adopts alumina whiskers as its carrier on the surface of a mother material comprising Fe-Cr-Al stainless steel. CONSTITUTION:A mother material 2 of a catalyzer 1 for a burner is composed of Fe-Cr-Al stainless steel is subjected to high temperature oxidation treatment ranging from 850 to 1,000 deg.C under oxidizing atmosphere, thereby forming alumina whiskers 4 whose length exceeds 0.1mum on the surface. Furthermore, the surfaces 2a of the alumina whiskers 4 and the mother material 2 are arranged to carry a catalyst 5 or an active substance designed to burn gases which contain methane gas to a large extent, such as natural gas without producing flames and at a low temperature around 600 deg.C. In this manner, catalyst combustion is carried out effectively. Furthermore, the mother material is composed of Fe-Cr-Al stainless steel, which improves its strength. Infrared radiation energy produced by a catalyst combustion and whiskers are dramatically increased so that heating effect may be improved, thereby enabling a catalyst combustion burner to be reduced in size as well.

Title: Electromagnet for accelerator
Inventor: CHIBA TOMOO
IPC: H05H7/04
Filed: 1995-07-05
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive, reasonable coil structure that suits the actual service conditions, for use in an electromagnet for an accelerator. SOLUTION: A coil wound on the magnetic pole portion of an iron core is formed of an insulated element wire 8 wound into layers which are bonded together with the adhesive of adhesion layers 41, the adhesion layers 41 having gaps 42 therein which make the adhesion between the element wires discontinuous. An epoxy resin is used as the adhesive of the adhesion layers 41 between the wires 8. Since the coil does not require the element wires to be intimately contacted with one another, it is continuously and gradually graded throughout its periphery to facilitate manufacture, thus varying its cross-sectional form throughout its periphery. The procedure of coil manufacture in conventional use is rationalized, resulting in a large reduction in cost.  A method which employs a coil adhesive that sets at room temperature does not require heating equipment and a molding die which were used conventionally in coil molding, and therefore has the effect of omitting a production process such as heating.

Title: Data processor
Inventor: KAWAI SHIYOUICHI
IPC: G06F15/02
Filed: 1986-07-19
Abstract: PURPOSE:To enable an operator to extract a sample data by actuating a random number generating means with the operation of the prescribed keys and displaying these generated random numbers. CONSTITUTION:An operator operates a random number key 16 for generation of random numbers. Thus a CPU 5 transfers the value T of a timer 84 set to a RAM 2 to an X register 85. The timer 84 is reset when one of plural operation keys of an operating part 7 is operated. Then the timer 84 starts its counting action when it is reset. The CPU 5 multiplies the count value T by the value B of a Y register 86 and stores the result of this multiplication in the register 85. The value of the register 86 is counted at random by a system program 65 of a ROM 6 and therefore the value C of the register 85 is equal to a random number. This random number is displayed on an LCD 3.

Title: Method for controlling ac electric motor and abnormality detection method
Inventor: TAJIMA KOICHI
IPC: H02P21/13
Filed: 1994-07-22
Abstract: PURPOSE:To accurately and quickly measure the primary resistance of an electric motor by eliminating an error due to the difference in phase angle by calculating the deviation between a magnetization current command value and a magnetization current detection value and controlling a power conversion means as a magnetization voltage command value. CONSTITUTION:An adder 11 calculates the deviation between a magnetization current command value from a command value generation circuit 10 and the magnetization current detection value from a voltage current control circuit 16 and outputs the deviation to an adjustment circuit 14. When the deviation between the magnetization current command value and the magnetization current detection value reaches O, the output of the adjustment circuit 14 becomes equal to the actual value of a primary resistance. By multiplying the estimated value of the primary resistance thus obtained by the magnetization current command value by a multiplier 15 and adding the value to the output of an amplification circuit 13 with an adder 12, the magnetization voltage command value can be obtained. The magnetization voltage command value controls a power converter 3 via a voltage/current control circuit 16, thus obtaining the estimation value of the primary resistance without greatly being affected by the accuracy of the detector.
