Title: Production of exothermic neck-down core and exothermic neck-down core
Inventor: MIKI MASAMITSU
IPC: B22C9/08
Filed: 1990-09-14
Abstract: PURPOSE:To eliminate the need for moisture removal particularly with a drying furnace and addition of particularly organic acid ester as curing agent by using an exothermic composition which contains aluminum powder as main raw material, as raw material and the water solution of alkali resol type phenol resin as binder, and forming a neck-down core having <=10% contracting ratio at the neck part. CONSTITUTION:The water solution of alkali resol type phenol resin is added to the mixed raw material composed of aluminum powder, iron oxide and zircon sand, and the neck-down core having <=10% contracting ratio at the neck part is formed. The moisture in the formed body is vaporized with the exothermic reaction of the aluminum powder in the mixed raw material with the water solution of alkali resol type phenol resin, and the cured neck-down core formed body can be obtd. The yield is improved, because gas defect is not developed on the surface of the casting, and the manufacturing process is simplified, because the drying furnace is unnecessary at the time of molding. Further, even in the case of the feeder head having large diameter, as the neck-down core having <= about 10% contracting ratio at the neck part can be used, cutting of the feeder head is so easy that this can be cut during shake-out work.

Title: Bolt fastening structure between disc-shaped body and shaft of rotary body
Inventor: MATSUMOTO TAKAHIRO
IPC: F04D19/04
Filed: 1986-10-15
Abstract: PURPOSE:To enable increase of bending rigidity, by a method wherein the portion, positioned closer to an axis, of the contact surface of the flange part of a shaft is notched, and a surface pressure produced available during fastening by means of a bolt is increased. CONSTITUTION:A notch 2d is formed in the portion, positioned closer to an axis than a bolt hole 4a, of a contact surface 2f of a shaft 2, The effective length of the contact surface 2f is limited to a low value. A spot facing 1c is formed in a disc-shaped body 1 part of the bolt hole 4a so that an effective length l of a bolt mounting seat surface is set to a value equivalent or slightly lower than the height of the head of a bolt 4. Thus, since the effective length of the contact surface 2f of the shaft 2 is limited to a low value and the effective length l of the bolt mounting seat surface of a discshaped body 1 is countersunk at the 1c, a surface pressure produced during fastening by means of a bolt is increased, and bending rigidity can be increased.

Title: Brushless motor
Inventor: MURATA HIROTAKA
IPC: H02P6/182
Filed: 1994-10-11
Abstract: PURPOSE: To commonly use a power source between a drive circuit and position detector by detecting the position of a rotor from a counterelectromotive force generated in each stator winding. CONSTITUTION: A counter electromotive force generated in each stator winding U, V, and W is divided by means of resistors R1-R5 and supplied to the input terminal of a comparator CMP. The output of the comparator CMP becomes a signal indicating the position of a rotor and is supplied to a microcomputer through a photocoupler PC and switching transistor Tr1. Since the position and direction changing point of the rotor is detected based on the counterelectromotive force generated in each stator winding U, V, and W and supplied to the microcomputer as the position signal of the rotor, no special position detector is required. Therefore, a power source can be commonly used between a drive circuit and position detector.

Title: Fuel cell
Inventor: UCHIDA MAKOTO
IPC: H01M8/02
Filed: 1992-09-16
Abstract: PURPOSE:To reduce size and weight, and improve economic property by using a gasket exhibiting high sealing property with low fastening pressure. CONSTITUTION:A gasket 21 is formed of a sponge sheet of independent bubbles 22, or formed into an integrated structure in which the sponge sheet of the bubbles 22 is adhered to both surface of a metal base. The gasket 21 is further formed into an integrated structure in which a rubber sheet is adhered to both surfaces of the metal base, and the periphery of its sealing part is subjected to protruding embossing finish. Since the sponge sheet of the bubbles 22 absorbs the thickness of an ion-exchange film 11 or the irregularities of a separator plate 2 by the compression of the bubbles 22, excellent sealing property can be provided with a small fastening pressure. Further, since the sponge sheet of the bubbles 22 is adhered to the metal base, the sponge sheet never escape to the outside by the adhesive force when a high pressure gas is used in the inner part, so that a highly precise working can be performed, and a linear seal can be also performed. Thus, a fuel cell can be reduced in size and weight, and economic property can be improved.
