Title: Facsimile signal coding circuit
Inventor: NAGATA KAZUO
IPC: H04N1/413
Filed: 1985-05-01
Abstract: PURPOSE:To attain always efficient code transmission independently of the degree of density of an original picture by applying conventional two-dimensional coding when the number of changing points from white to black or vice versa of an input picture signal is smaller than a preset threshold value and applying non-compression coding when the number is equal to the threshold value or over. CONSTITUTION:A coding controller circuit 2 sets a reference color (white) into an opposite color (black) and a picture signal is inputted until a changing point detection circuit 1 detects the changing point again. When a changing point is found out, the changing point detection circuit 1 sends run length information to a compression code sending circuit 3, a changing point detection signal 113 is inputted to a counter 21, which is increased by 1. Then the operation above is repeated for one line of picture signal until all the detection of changing point is finished, and a comparator 22 compares the value of the counter 21 with a preset threshold value 114 at the end of one line. When the value of the counter 21 is larger, the compression coding system is stopped on the next and succeeding lines, and a coding system command signal 116 is set to '0' to apply the non-compression coding to bring the system into the non-compression coding system.

Abstract: PURPOSE: To reduce the space of a covering mechanism and to enable a smooth closing and opening of the cover, by a method wherein an elastic beam is located at an open portion of a printer of a device body, such as an electronic portable computer and the like, and a stopper is placed at a cover.  
     CONSTITUTION: Engaging piece 6 of the printer cover 2b are inserted into the device body 1, and engaging pieces 7 are mated with a device body 1 by bending them centering around a fulcrum 9b of a ledge 9 with the stopper 12 abutted on to the elastic beam 8. The elastic beam 8 pressed by the stopper 12 is always somewhat bent, and thereby the engaging pices 7 are not unhooked from the device body 1 easily. Where the cover 2b is removed, a knurling 5 of the cover 2b is pressed in the direction of an arrow mark with a finger 11, which results in causing the stopper 12 to bend the elastic beam 8. And thereby mating of the engaging pieces 7 and the device body 1 is released. Furthermore, a staged portion 9a of the ledge 9 is formed in the device body 1, wherby the cover 2b rotates centering around the fulcrum 9b, and the engaging pieces 7 are removed from the device body 1. The cover 2b can thus be removed from the device body 1.

Filed: 1981-06-16
Abstract: PURPOSE:To increase noise margin to an input voltage with a low level even with a small threshold voltage of an enhancement MOSFET, by using a substrate effect of the MOSFET. CONSTITUTION:When a voltage between a source and a substrate of an input device is increased, the threshold voltage of the input device is increased due to the substrate effect. When an input signal IN is at a low level, a gate voltage of an input device Q4 and MOSFETQ5 of depletion type is low, a mutual conductance gm of FETs Q4 and Q5 is decreased and the output of an inverter of MOSFETs Q3 and Q4 goes to high level. Then, a MOSFETQ6 is conductive to boost the potential of a source N3 of the FETQ4, allowing to increase the substrate effect further. The output of an inverter circuit 8 goes to low level and a MOSFETQ7 is not conductive. When the signal IN is at a high level inversely, the gm of the FETs Q4 and Q5 is increased and the FETQ6 is not conductive. Further, the FETQ7 is conductive, the potential of the source N3 is lowered and the substrate effect can be decreased.

Abstract: PURPOSE:To contrive to improve the efficiency of an apparatus by preventing a DC component from flowing out through providing a mass storage capacitor to be connected in series with a load on the AC output side of a solar battery (PV) inverter. CONSTITUTION:A mass storage capacitor 2 is connected in series with a load on the AC output side of a PV inverter using a solar battery 1 as a power source, the voltage of said capacitor 2 is monitored, and said inverter is stopped and separated from a system when said voltage is abnormal. That is, a DC component essentially does not flow out by said mass storage capacitor 2. However, because said DC component is generated between terminals of the capacitor 2 when the DC component transiently flows out due to the defectiveness of the element of an inverter bridge 3 and the abnormality of a control circuit 12, it is necessary to detect said DC component and to stop the inverter. Then, when said inverter is separated from the system, a DC shunt current is prevented and the transient DC component is detected in a short time and prevented from flowing out.
