摘要:
A brush holder structure in an electric motor in which brush holders for housing brushes held in slidable contact with a commutator provided on a rotor shaft and an end bracket for rotatably supporting the rotor shaft are both integrally molded with a gear frame for housing and supporting a worm gear mechanism. The worm gear mechanism includes a worm formed around the distal end portion of the rotor shaft and a worm wheel held in mesh with the worm. A lead-out groove for leading out a pig tail extended from each brush is formed in a proximal end side wall of each brush holder with respect to the rotor shaft, and a receiver for receiving resilient spring fitted in each brush holder to press each brush against a commutator is disposed between two proxiamal and distal end side walls of each brush holder. The receiver extends in the axial direction of the rotor shaft, and is set to have its width not exceeding the width of the lead-out groove in the circumferential direction of the rotor shaft. The brush holders having the receiver can be simply molded by setting first and second molds in butt relationship against a main mold.

A method of manufacturing a laminated electronic part includes fabricating first and second laminated sheets by laminating an insulating function layer made of an unsintered ceramic material and a conductor layer, having a plurality of conductors two-dimensionally arranged in a vertical direction and in a horizontal direction to make up part of circuit components; cutting the first and second laminated sheets into sticks to create a plurality of first and second laminate sticks; fabricating a third laminated sheet by rotating the second laminate sticks by 90°, arranging the second laminate sticks to be each sandwiched between the first laminate sticks, and thermocompression bonding them for integration; singulating the third laminated sheet into chips and creating sintered bodies by sintering the unsintered chips to integrate the first laminate with the second laminate.

A seal member is attached to a cover which occludes a gear case as a housing unit. The seal member is formed of elastomer and integrally formed with: a plate-shaped portion formed into a disc shape which covers the inner surface of the cover; an inner seal portion which is positioned on the inner peripheral edge of a through-hole, and comes into sliding contact with the outer peripheral surface of an output member; an outer seal portion which is positioned on the periphery of the cover, and comes into contact with the opening end of the housing unit; and anchor portions which latch onto the front surface of the cover via mounting holes provided to the cover. The boundary between the seal member and the cover extends only to the outside of the gear case, and does not extend to the inside of the gear case.

A method of producing an α-L-aspartyl-L-phenylalanine-β-ester by forming the α-L-aspartyl-L-phenylalanine-β-ester from L-aspartic acid-α,β-diester and L-phenylalanine using an enzyme or enzyme-containing substance that has an ability to selectively link L-phenylalanine to an α-ester site of the L-aspartic acid-α,β-diester through a peptide bond.

A communication apparatus includes a display unit, a communication unit, and a control unit. The display unit displays video data. The communication unit communicates with an external apparatus. The control unit controls the communication apparatus in accordance with a command received by the communication unit. If the display unit is in a mute state and the communication unit is sending the external apparatus the data for placing the external apparatus in a mute state, the control unit determines not to control the communication apparatus in accordance with the command.

摘要:
DNA and recombinant DNA that encode a peptide-forming enzyme, a method for producing a peptide-forming enzyme, and a method for producing a dipeptide are disclosed. A method for producing a dipeptide includes producing a dipeptide from a carboxy component and an amine component by using a culture of a microbe belonging to the genus Sphingobacterium and having the ability to form the dipeptide from the carboxy component and the amine component, a microbial cell separated from the culture, treated microbial cell product of the microbe or a peptide-forming enzyme derived from the microbe.

摘要:
A method is disclosed that allows the production of peptides having three or more amino acid residues easily, inexpensively and at high yield without going through a complex synthesis method. A novel enzyme that efficiently produces a peptide from bacteria belonging to the genus Empedobacter or the genus Sphingobacterium is provided. The enzyme acts on a carboxy component and an amine component to form peptides having three or more amino acid residues by acting on a carboxy component and an amine component.
