Title: Method and device for manufacturing rare-earth-fe-n magnetic material
Inventor: TAKAHASHI TAKESHI
IPC: H01F1/059
Filed: 1993-11-22
Abstract: PURPOSE:To nitride a large amount of rare-earth-Fe-N magnetic material at once by eliminating the possibility of the magnetic material being thermally decomposed into a rear-earth nitride and alphaFe at the time of nitriding the magnetic material. CONSTITUTION:The powder (processed material) 2 of a rare-earth-Fe material is put in a reaction tank 1 having an adequate number of projections 3 on its internal surface and, when the tank 1 is heated while a nitriding gas is introduced into the tank 1, the tank 1 is rotated or swung. Since the projections 3 stirs the processed material 2, the heat radiating effect is accelerated and the temperature rise of the material 2 caused by accumulated heat of reaction can be suppressed.

IPC: H05K13/02
Filed: 1988-11-17
Abstract: PURPOSE:To easily pack or unpack chip parts and, at the same time, to improve the packing ratio by successively taking out the chip parts from grooves for taking out chip parts at bottoms of vertical through holes aligned in one line while a jig main body is tilted after the chip parts are dropped down into the grooves through each through hole by vibrating the jig main body and orienting member held in the vertical direction. CONSTITUTION:An appropriate quantity of chip parts 5 are put in the parts supplying chamber 6 of an orienting member 2 after a jig main body 1 and the member 2 are aligned in the vertical direction and the main body 1 is vibrated. As a result, the parts 5 fall down into through holes and fill up the holes 4 in a state where the parts 5 are vertically arranged in each hole 4. Then the member 2 is removed and the main body 1 is brought to an assembling and packaging device on which the main body 1 is mounted in a tilted state with a cover body 3 at the lower section of the main body 1 at bottom. After mounting the main body 1, the cover body 3 is removed. Then the chip parts 5 put in grooves 4a for taking out chip parts appear in a line across the grooves 4a. The exposed parts 5 are taken out one by one by means of a picking-up means. When the parts 5 at the bottom of the holes 4 are taken out, the parts 5 on the taken-out parts 5 fall into the grooves 4a and become ready for being taken out.

Title: Spring bracket and fixed support cylinder for cooking utensil thermister device
Inventor: EGUCHI YOSHIO
IPC: H01C7/04
Filed: 1994-11-01
Abstract: PURPOSE: To reduce processing cost by integrating a spring seat and a fixed support cylinder with each other via a plurality of deep drawing processes for stainless steel, phosphor bronze or brass flat plates. CONSTITUTION: A fixed support cylinder 6 and a spring seat 7 are original plates formed out of stainless steel, phosphor bronze or brass flat plates, and a deep drawing press is used to subject the plates to gradual deep drawing processes, thereby concurrently forming all of an engagement section 19, the seat 7, the cylinder 6, and the lower end small diameter section and the internally drawn section into an integrated state. This structure becomes substantially more inexpensive than the case of the conventional caulking method, and the good appearance of a deep drawing section can be obtained, due to the formation thereof through a plurality of deep drawing processes. Also, a separate deep drawing press is used to form a cap 14 out of a flat original plate of the same quality at a deep drawing process. The cap 4 so made is placed on a mold.  Then, the internally drawn section of the cylinder 6 at the lower end small diameter section is inserted in the cap 4 from an upper level and hammered with a punch. As a result, an inner folded section is bent, wound around the internally drawn section and easily fixed thereto. Thus, this method becomes inexpensive, compared with the conventional method for pressing in the cap.

Title: Method and apparatus for simultaneously removing nitrogen and phosphorus by biological membrane filtration
Inventor: TOMITA YOSHIO
IPC: C02F9/00
Filed: 1989-11-10
Abstract: PURPOSE:To make a reaction tank compact, to prevent the pH rise of treated water and to simultaneously remove nitrogen and phosphorus by adding to raw water a hydrogen donor and an acidic inorg. flocculant whose molar ratio to phosphorus in the raw water is a specific value to form microflocs and subsequently filtering the microflocs by a biological membrane in a denitrifying tank. CONSTITUTION:Raw water is quantitatively supplied to a floc forming tank 5 by a pump 4 but, on the way of supply, a hydrogen donor such as methanol and an acidic inorg. flocculant are added. The acidic inorg. flocculant is added in a molar ratio of 1-3 times phosphorus in raw water because phosphorus can not be sufficiently removed in the case of below one time and the removal ratio of phosphorus is not enhanced corresponding to the increase of the addition amount even in the case of 3 times or more. By this method, a denitrifying tank 7 is made compact and a sedimentation/flocculation tank becomes unnecessary. Since the acidic inorg. flocculant is used, the pH rise of treated water can be prevented and nitrogen and phosphorus can simultaneously be removed.

Abstract: PURPOSE:To measure the processing time for an interruption processing routine without using an exclusive measuring equipment and without changing the interruption processing routine concerned of an object to be measured. CONSTITUTION:By the processing of S10, an interruption becomes enable, and the processing of S11 is looped until the value of an interruption counter becomes the value of 'number of times-1 of a target interruption whose measurement is desired'.

Abstract: PURPOSE: To improve the cleaning effect of a magnetic head by providing a compressed air jetting means for jetting compressed air to a card in a direction in which the card moves to the magnetic head side. CONSTITUTION: When being carried to each of the magnetic heads H1, H1', H2, H2', H3 and H3', a passenger ticket (a) is moved as if it were pressed against the magnetic heads H1 to H3 sides located below by a pinch roller.
