Title: Interruption control circuit
Inventor: KITAGUCHI TAKAHISA
IPC: H04L25/40
Filed: 1986-04-25
Abstract: PURPOSE:To latch the detection output by a clock after reset release even if the detection output rise in a reset section to inform reception detection to a CPU by providing a latch circuit between a reception detecting circuit and an edge trigger type interrupt control circuit. CONSTITUTION:When a reception detecting circuit 1 detects a reception code from a line, its output DT is taken into a latch circuit 2 synchronously with the rise of a clock CLK2: and when a latch output LT is supplied to an edge trigger type interrupt control circuit 3, the circuit 3 outputs an interrupt signal LS. A CPU 4 sends a reception detection confirmation signal AK in accordance with the signal LS. A reset circuit 5 gives a reset signal RS2 different from a reset signal RS1 to circuits 1 and 2 by the signal AK. As a result, the output DT is latched synchronously with the signal CLK2 to send the signal LS to the CPU 4 even if the rise of the detection output DT occurs in the reset period due to the signal RS1.

Title: Close contact image sensor
Inventor: AOTA KOICHI
IPC: H04N5/369
Filed: 1988-04-20
Abstract: PURPOSE:To reduce in size a whole device and to improve the reading accuracy of an original by disposing a photoelectric converter at a position which receives the reflected light of a light radiated to the original through a photoconductive passage, and providing two polarizing layers in which polarizing directions are optically displaced. CONSTITUTION:An illumination light radiated from an illumination light source 9 is linearly polarized by a second polarizing layer 8 to be incident into a photoconductive passage 7. The light incident into the passage 7 is absorbed by a first polarizing layer 6 without transmitting from the layer 6 of the lower face of the passage 7 downward due to the layer 6 in which its polarizing direction is optically displaced at 90 deg.. On the other hand, the light illuminated to an original 11 through the upper face of the passage directly above the vicinity of a photoconductive layer 3 of the light incident into the passage 7 is disordered in its linear polarization when it is reflected and scattered on the surface of the original 11. Thus, the reflected and scattered light passed through the passage 7 upon reflection on the original 11 can transmit the layer 6 and arrive at the layer 3 through a transparent electrode 4.

IPC: H01B13/02
Filed: 1987-04-21
Abstract: PURPOSE:To obtain a compressed wire with no collapse and no irregularity in its stranding state by installing a pre-stranding device and a second stranding device. CONSTITUTION:A rotary operation of a pre-stranding device 5 is used to strand a central conductor 1 and peripheral conductors 2, which are collected by a stranding base 4, by the number of revolutions. Their stranded conductors are made to pass through a compression dice 6 via guide roller 52 and run to a guide roller 53. After they are made to pass through the pre-stranding device 5, they enter a second stranding device 8. When the revolution of a flyer 81 in the second stranding device 8 is set to be identical in its direction with the revolution in of the pre-stranding device 5 and to be approximately half in the number of revolution in the pre-stranding device 5, the stranded conductors are returned nearly in half in their stranding states after they pass through the pre-stranding device 5, and so they are returned to be in their original stranding states after they pass through a guide roller 87. The conductors 1 and 2 collected by the stranding base 4 are thus formed into a stranded wire whose periphery is shaped in a smooth circle. When external coating is provided for this stranded wire, its coating thickness becomes uniform. This stranded wire which does not collapse in its stranding state and is uniform can be obtained accordingly.
