When a branch instruction is decoded by the instruction decoders 409a-409c, the upper 29 bits of the PC relative value included in the branch instruction are sent to the upper PC calculator 411 and the lower 3 bits are sent to the lower PC calculator 405. The lower PC calculator 405 adds the lower 3 bits of the PC relative value and the lower 3 bits of the present lower PC 404 and sends the result to the lower PC 404 as the updated lower PC. The upper PC calculator 411 adds the upper 29 bits of the PC relative value, the upper 29 bits of the present upper PC 403, and a carry that may be received from the lower PC calculator 405, and sends the result to the upper PC 403 as the updated upper PC.

A pulverization/classification apparatus includes a plurality of air nozzles, a milling chamber as a space for pulverizing particles by compressed air jetted by the air nozzles, and a rotor installed at an upper part of the milling chamber that classifies powder materials flowing into the rotor from the milling chamber with centrifuging into fine particles and coarse particles. The rotor includes plural blade members, and a width of the blade members within the rotor are set to be 1/50- 2/25 of the rotor's diameter.

In a screen printing apparatus for contacting a lower surface of a mask plate with a substrate and moving a squeezee in a sliding motion on an upper surface of the mask plate thereby printing a paste onto the substrate, mask bend preventing members are mounted on conveying rails at front and rear parts of clamp members clamping the substrate in a Y-direction, and, at a mask separating operation after printing, the substrate is lowered while the lower surface of the mask plate is supported by the clamp members and the mask bend preventing members. Thus the mask separation can be achieved in a state where the mask plate is supported from below on four sides of the substrate and is thus prevented from a downward bending, and a satisfactory mask separating property can be ensured over the entire substrate.

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.

In a screen printing apparatus which prints solder cream on a substrate by a closed type squeeze head, in print space 35 that houses the solder cream 5 pressurized in a paste storing part and brings the solder cream 5 into contact with a surface of a mask plate, a hollow heat regulating member 37 provided in a horizontal direction orthogonal to a squeezing direction is caused to pass, and a heat regulating medium is circulated inside the heat regulating member 37 by a heat regulator 40, whereby the solder cream 5 in the print space 35 can be always kept at an appropriate temperature and at an appropriate viscosity, so that print quality can be secured.

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.
摘要:
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.
