摘要:
A method for chamfering an edge of a silicon steel plate moving in the longitudinal direction of the edge by applying an entirely circular edge tip of a ring-shaped cutting edge portion of a circular cutter to the edge of the plate material while rotating the circular cutter. The edge tip of the cutting edge portion of the cutter has a rake angle which is within the range of 0 to -1.0 degrees and a relief angle which has a zero or positive value.

A high speed address calculation circuit for a pipeline-control-system data-processing apparatus includes an instruction register, a register file, an address register, a first data selector, an increment register, a second data selector, a decoder, an adder and a third data selector. The instruction register stores instructions from a memory, and the register file is addressed by the register designation data of the instructions stored in the instruction register. The address register stores an operand address, and the increment register stores increment data calculated in an arithmetic unit. The first data selector selects either the address from the address register or the data from the register file, and the second data selector selects either the data from the increment register or the destination field data included in each instruction. The decoder generates a signal to specify the data to be selected by the first and second data selectors. The adder receives data from the first and second selectors and provides an operand address. The third data selector receives the operand address from the adder and the address generated by the arithmetic unit, selects one of these addresses, and transfers the selected address to the address register.

An image forming apparatus includes an original document transfer section for transferring a document to a predetermined position, a scanning section for scanning the document, an image forming section and a control device for controlling the functional sections. The control device energizes the exposure lamp in the scanning section at a predetermined time, before the document reaches a predetermined position, and starts the movement of the exposure lamp toward the start position of the effective scanning operation.

Reception signal processing apparatus in nuclear magnetic resonance diagnostic apparatus to display as an image the distribution of the spin density or relaxation time of specified atomic nuclei existing in an object utilizing nuclear magnetic resonance phenomena including a phase demodulator for phase demodulating a nuclear magnetic resonance signal evoked by nuclear magnetic resonance phenomena in accordance with two reference waves whose phases are different from one another by 90.degree., an analog-to-digital converter for digitalizing the separated two signals obtained by the phase demodulator, and a phase correction processor for automatically correcting the phase difference between the reference waves and nuclear magnetic resonance signal to produce a frequency spectrum by processing the digitalized signals.
摘要:
Joining end faces of semicircular magnetic rotor halves are adhered to form a disc-shaped rotor. Magnetic heads are formed at two ends of one of the joining end faces. A magnetic head core and a coil pattern for exciting the core of each of the magnetic heads are formed by alternately depositing magnetic films, insulating films or nonmagnetic conductive films in accordance with thin-film formation techniques. A groove having a triangular cross section is formed at an intermediate portion between the magnetic heads along the thickness of the given rotor half. The center of rotation of the rotor is defined by the groove. Therefore, the line connecting the distal ends of the gaps of the magnetic heads passes through the center of rotation of the rotor and a middle point of the line precisely coincides with the center of rotation. A pair of rotor coil patterns are formed on an upper surface of the rotor to be concentric with the center of rotation in accordance with thin-film formation techniques. These rotor coil patterns serve as rotors of a rotary transformer. Each rotor coil pattern is connected to the corresponding magnetic head through connecting conductors formed on one of the joining end faces in accordance with the thin-film formation techniques.

A door hinge device comprises a door support member and a door mounting member. The door support member is provided with a tongue, and is attached to a refrigerator housing. The door mounting member is attached to a door, and is provided with a second coupling portion connected to the tongue. A shaft and a guide pin stand on the tongue, and each is loosely fitted with a cylindrical collar. The door mounting member is provided with a shaft fitting slot which extends along the depth of the refrigerator housing when the door is closed, and the shaft is fitted in the shaft fitting slot. A guide recess is formed at the rear portion of the second coupling portion to engage the guide pin. The guide recess and the guide pin jointly move the shaft along the shaft fitting slot when the door is located near the position to close an opening of the refrigerator housing, and rocks the shaft relative to the shaft fitting slot until a given angle is formed between the door and the refrigerator housing when the door is kept away from the position to close the opening.
