Title: Instruction pre-read control system
Inventor: KOIKE JUN
IPC: G06F9/38
Filed: 1986-02-20
Abstract: PURPOSE:To perform the branch instruction at a high speed by holding a pre- read instruction and producing a branch address of the branch instruction selected by a decoder to store, to read as necessary and to set the produced address to an address counter. CONSTITUTION:The pre-read instruction read by an address counter 2 is stored in a pre-read memory 3 and also inputted to a decoder 5. The decoder 5 decides only a fact that the input instruction is equal to a branch instruction that has no reference to a general-purpose register which can be changed optionally in a program and calculates a branch address through an address generating circuit 6 to store it in a branch address store memory 4. Then the branch instruction is read out of the memory 3 and interpreted by an instruction execution control part 7 to be branched. Thus the branch address calculated previously is read out of the memory 4 and set to the counter 2. The counter 2 gives an access to the set branch address and therefore fetches the branch address instruction.

Abstract: PURPOSE:To attain the on/off of the muting function without generating pop noise at a low voltage operation, by providing a driving section of common base and an output stage of common emitter, and feeding back the output of a power amplifier section to the driving section. CONSTITUTION:When a switch S is applied from the nonmuting state into the muting state, constant current sources 11, 12 are turned off and TRsQ3, Q4...

IPC: G03G15/00
Filed: 1991-02-06
Abstract: PURPOSE:To reduce fluctuation of light amount at a document reading position and downsize a device by providing a main body upper frame of a specific form. CONSTITUTION:A main body upper frame is divided into a light source side main body upper frame 6 and an opposed main frame upper frame 6' at a document reading position A. The center part of the light source side main body upper frame 6 on a document reading position A side is projected toward the opposite side main body upper frame 6'. When a lamp 1 illuminates a document 4, light is transmitted through a document stand glass plate 5 over the light source side main body upper frame 6 to illuminate the copy 4. A read reflected light from the document 4 is transmitted again through the document stand glass plate 5 and forms an image on a sensitive body 9 in a cartridge just below the reading position A of the document by means of a collecting lens array 8. Thus, in a copying machine without a reflection hood, the amount of light arriving at the surface of the document 4 is restricted to compensate a deviation of light amount in the longitudinal direction with which a lamp 1 itself is provided.

IPC: H01S5/06
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To perform modulating operation adequately in the broad range of a laser light emitting region from a natural light emitting region, by forming a semiconductor laser driving signal in correspondence with the deviation between a light-amount command signal and a feedback signal, and overlapping a driving current in correspondence with the signal in linear and nonlinear patterns. SOLUTION: A light-amount command signal S for driving a semiconductor laser LD is inputted into a terminal 11. A monitoring circuit 400 receives the light from the laser LD with a photodiode PD, outputs a light-amount monitoring voltage signal M, negatively feedbacks the signal to a driving control circuit 200, and performs control. A linear driving-current output circuit 300 amplifies the laser driving signal outputted from the driving control circuit 200. A nonlinear driving-current output circuit 500 outputs the signal in correspondence with the nonlinear pattern with the increase and the decrease of the laser driving signal and controls the gain of the laser light emitting region from the natural light emitting region. At the rising-up time of the driving current, the driving current, which is in proportion to the inverse number of the emitted light amount for the injected light of the laser LD, flows and is overlapped on the output current of the linear output circuit 300.
