摘要:
A screen printing apparatus and method in that in the print parameter setting process for setting print parameters including a squeegee movement speed, a printing pressure, and plate release conditions, a squeegee movement speed at which the squeegee is to be moved is set at the first step, then a printing pressure for realizing a desired cream solder charging state is set at the second step, and then plate release conditions for realizing a desired cream solder transfer state is set at the third step. Therefore, the print parameter setting process can be performed according to an efficient processing procedure and trial-and-error-based backward work can be avoided. Print parameters can be set quickly and properly for a wide range of solder types.

A circuit group control system which receives from a master processor a first command sequence and a second command sequence each of which is composed of a plurality of commands, each command being to be executed by one of a plurality of circuits, and causes any available circuits to execute the commands one by one in order of arrangement in each command sequence. The circuit group control system achieves concurrent execution of a plurality of command sequences by causing a circuit (a second circuit) to execute a command in the second command sequence while another circuit (a first circuit) is executing another command in the first command sequence.

A processor which decodes and executes an instruction sequence includes: a state hold unit for holding, when a predetermined instruction is executed, a renewal state for an execution result of the predetermined instruction; an obtaining unit for obtaining an instruction sequence composed of instructions matching instructions assigned to an instruction set of the processor, where the instruction set is assigned first conditional instructions, a first state condition for a first conditional instruction being mutually exclusive with a second state condition for a second conditional instruction which has a same operation code as the first conditional instruction, the instruction set not being assigned the second conditional instruction, and the first state condition and the second state condition specifying either of one state and a plurality of states; a decoding unit for decoding each instruction in the obtained instruction sequence one by one; a judging unit for judging whether the renewal state is included in either of the state and the plurality of states specified by the first state condition in the first conditional instruction, when the decoding unit decodes the first conditional instruction; and an execution unit for executing, only if a judgement result by the judging unit is affirmative, an operation specified by the operation code in the first conditional instruction decoded by the decoding unit.

A disk recording and/or reproducing apparatus includes: a loading mechanism for drawing a disk having been inserted through an opening portion into the apparatus or drawing the disk having been held in the apparatus out of the opening portion; and an opening/closing sheet having first and second opening/closing portions, the first and second opening/closing portions being deformed by the disk to thereby open/close the opening portion. At least one of the first and second opening/closing portions has at least one deforming portion for facilitating the deformation of the opening/closing portion when the opening/closing portion is deformed by the disk carried by the loading mechanism.

When a subroutine call instruction is transferred from the instruction memory 39 to the IDB 29 and decoded by the decoder 18, the following operations (1)-(3) are executed in parallel: (1) a return address storage operation for incrementing the value stored in the PC 15 using the INC 16 and for storing the incremented value in the LR 13 as a return address; (2) a branch operation for storing the entry address of the subroutine included in the subroutine call instruction in the PC 15; and (3) a stack reserve operation for preparing for the following use of a stack area by adding a value “−4” to the value stored in the SP 12 using the adder 22 and for storing the addition result in the SP 12.

An electric motor used for example in a magnetic disk drive, comprises a rotor having a hub on which the magnetic disk is mounted, and an annular driving permanent magnet, and rotating together with a rotary shaft, and a stator disposed outside the rotor, having a core and coils wound on the core. A signaling permanent magnet for detecting the rotary angle or the rotational speed of the rotor may be provided on the radially inner side of the driving permanent magnet. Part of the outer periphery of the stator core may be retracted radially inward or cut away to form a concavity or an open part. A magnetic shielding plate may further be provided to cover the coils, with part or the entirety of the magnetic shielding plate being positioned closer to the rotary shaft than the outermost periphery of the rotor to prevent the escape of the rotor in the direction of the rotary shaft. The stator core may be provided, at its inner extremities, bent portions extending in the direction parallel with the rotary shaft, and away from the hub. Alternatively, the midpoint of the stator core may be positioned farther away from the hub than the midpoint of the driving permanent magnet.
