Abstract: PURPOSE:To contrive the good balance between the reliability of a memory and the processing speed of a direct memory access controller DMAC, by using a circuit which produces a signal to control the output of a bus cycle period generating circuit in response to the output of a memory check selection signal generating circuit. CONSTITUTION:The signal which is produced from the memory check selection signal generating circuit 7 and decides the execution of the memory check is selected via a selector circuit 9 together with a control signal A serving as a control signal for the bus cycle period of CPU1 or DMAC2 when the memory check is performed and the control signal B when no memory check is respectively performed. Then the desired bus cycle periods are obtained for both the CPU1 and the DMAC2 respectively. The memory error signal produced by a memory check circuit is masked when no memory check is carried out.

Filed: 1987-05-20
Abstract: PURPOSE:To enable generation of a character symbol pattern with various shadows by providing an output means which outputs data overlapped to a position which is shifted prearranged dots from a pattern generated by a pattern generation means. CONSTITUTION:When a code corresponding to a character A is received from a data source 2 and is printed out, CPU 3 first reads an ordinary character pattern of A from a character font ROM 6 according to data within a character font area 7b, and develops the ordinary character pattern in a black image buffer memory 8. Next, the CPU 3 reads an italic character pattern (becomes a shadow part) from the character font ROM 6 in conformity with data in a shadow character font area 7c and stores the pattern in a red image buffer memory 9. At that time, however, a few dots each (one dot each in the embodiment) are developed, shifted to (-) position, in a horizontal and a downward (x, y) direction from a position where the ordinary character pattern is stored in the black image buffer memory 8.

Title: Direct digital synthesizer
Inventor: IDE TERUJI
IPC: H03B28/00
Filed: 1995-05-19
Abstract: PURPOSE: To improve the operating (output) frequency by storing waveform data to obtain a desired frequency and waveform from phase data being outputs of a phase accumulator to a memory, transferring the data to a 2nd memory and reading waveform data from the 2nd memory. CONSTITUTION: Digital data corresponding to a frequency set as an input are given to a phase accumulator 1. Every time a reference clock is given to the accumulator 1, input data are accumulated. Its output is given to a 2nd waveform memory (RAM) 6 as phase (frequency) information corresponding to address data of a conventional waveform memory (ROM) to a 2nd waveform memory (RAM) 6. Since a content of waveform data stored in a 1st waveform memory (ROM) 2 is transferred to the memory 6 by starting a bootstrap circuit 5 just after the input of a power supply of a synthesizer, the same content as that of a conventional memory is stored in the memory 6. Desired waveform data corresponding to phase information received by the memory 6 are outputted synchronously with a reference clock and outputted via a D/A converter 3 and a filter 4.

Title: Serial printer
Inventor: OTA YOSHIAKI
IPC: B41J2/51
Filed: 1988-05-18
Abstract: PURPOSE:To obtain a serial printer which accepts a compact power supply by providing a means to make variable the timing for printing of first and second head pin strings in accordance with a printing mode by which different printing intervals are designated. CONSTITUTION:If data which indicates a printing mode I is entered into a printing mode control section 1 from a host device, the offset amount between the printing times of an L pin and an R pin is calculated by a printing mode control section 1. However, the offset amount is so preset that the overlapping area of an electric current supplied to the L pin and that to the R pin is minimized. Consequently, printing is performed without controlling the offset of printing time. Next, if data which indicates the printing mode II is entered, the offset amount between the printing times of the L pin and the R pin is calculated by the printing mode control section 1 and a control signal which controls the offset so that the overlapping area of the current supplied to the L pin and that to the R pin becomes small, is output.

Filed: 1992-05-14
Abstract: PURPOSE:To improve manufacturing work performance and enable the easy replacement of optical fibers by twisting plural optical fibers inside a porcelain tube, and separating them at both end parts of the porcelain tube to support them fixedly. CONSTITUTION:Two optical fibers 9 are inserted into a through hole 1a and twisted only once. The parts close to both ends of the respective fibers 9 are separated and fixed to holders 11 by fasteners 12, and both ends thereof are connected to airtight terminals 13. An insulating fluid is then filled into both containers 10 and the through hole 1a of a bushing 1. Since two optical fibers 9 are thus supported being twisted in the through hole 1a, deflection is hardly generated even if external force such as earthquake is applied thereto. Manufacture is easy, and the replacement of the optical fibers 9 with new ones can be performed easily by removing the insulating fluid filled in both containers 10 and the through hole 1a of the porcelain tube 1. In this case, both containers 10 and the porcelain tube 1 can be used again.

Abstract: PURPOSE:To easily prepare a program by reading out the data of an address, which is operated according to the program and designated by a value held in a holding means, from a coefficient data memory and executing arithmetic by using a data including the coefficient data. CONSTITUTION:When a flag showing the arithmetic result of an ALU 8 is held in a flag register 10, a condition data for discrimination is supplied from a sequence controller 17 to a decision circuit 23. This data is included in the instruction of the program. When the contents of the register 10 are coincident with the condition data, the circuit 23 generates a switching signal. Consequently to this switching signal, a switching circuit 29 repeats and outputs the address data to be supplied from the controller 17. When they are not coincident, the circuit 29 repeats and outputs the address data showing a 0 address. Corresponding to the instruction signal from the controller 17, either the output of a +1 adder 27 or the address data showing the 0 address is selectively outputted from a switching circuit 29. An adder 30 adds address data values to be outputted from the circuits 28 and 29, and the result of the addition is held.
