Title: Signal level shifter
Inventor: HAGA KAZUKIYO
IPC: H03K19/0175
Filed: 1995-02-22
Abstract: PURPOSE: To avoid the influence of jitter, etc., by inputting a signal from the junction of a constant voltage element and a resistor, amplifying it and outputting a level shifted signal. CONSTITUTION: An output voltage from an output TR122 of a bipolar transistor Tr circuit 10 is impressed to a level shift circuit 20 and a current flows to diodes D1-Dn and a resistor R21. At such a time, the amplitude of a signal supplied to an input terminal (c) of the circuit 20 is level-shifted by the forward rising voltage of the plural diodes D1-Dn. Then, that signal is outputted to an output terminal (d) at the junction of the diode Dn and the resistor 21. The differential voltage of the signal outputted to the terminal (d) and a reference voltage VREF is amplified by a current mirror circuit 30 and outputted from the output terminal. Thus, the input signal of the circuit 10 is level-shifted and appears at the output terminal of circuit 30.  In this case, the amount of shift at the circuit 20 is decided by the difference between the average value of the amplitudes of output signals from the circuit 10 and the average value of the amplitudes of signals to identify input signals at the circuit 30.

Abstract: PROBLEM TO BE SOLVED: To make the whole of a metal fitting smaller and lighter by mutually approaching and separating a pair of sandwiching members according to the thickness of a rising wall and fastening them through a fastener. SOLUTION: In the case of using a support receiving metal fitting, a fastener 9(a screw shaft part 13) is loosened to make sandwiching members 1, 2 turn into a state where they can mutually freely approach and separate within the range of a slot 7. Next, the sandwiching members 1, 2 are externally fittedly mounted on the upper end part of the rising wall. In a state where both the sandwiching members 1, 2 are mutually approached to sandwich the upper end part of the rising wall between both vertical plates 3, 4, the fastener 9 (a screw shaft part 13) is rotated in a fastening direction by utilizing a bolt head 14a protruding toward the upper end of the fastener 9 to mutually fix both the sandwiching members 1, 2. After this, the lower end of a support for supporting a concrete form on an upper floor is externally fitted on a vertical shaft part 10.  Thus this support receiving metal fitting can be wholly composed smaller and lighter than a usual support receiving metal fitting to use a usual channel-type clamp which is composed in consideration of the maximum thickness of the rising wall, and moreover inexpensively executed.

Title: Method for discriminating dot photography area
Inventor: IBARAKI HISASHI
IPC: H04N1/00
Filed: 1985-02-23
Abstract: PURPOSE:To make it possible to identify a dot area in a picture signal with a simple circuit by dividing a half tone picture signal into several number of blocks that consist of multiple picture elements and deciding whether it is a dot area or not by measuring the change of the signal level of the picture element in the block both in the direction of a main scanning and of a subscanning. CONSTITUTION:The picture element is stored at registers 31 and 32 in a prescribed order by a memory address controller 4. A difference between the picture elements inputted to the registers 31 and 32 is calculated at a subtracter 5 and the subtracted value is inputted to registers 61 and 62 in order. The signal of difference of the registers 61 and 62 detects a positive/negative change by a positive negative change detection circuit 7 and a counter selector 8 decides that the detected result is whether in the direction of the main scanning or of the subscanning by the memory address controller 4 and transmits the result of the detection to either one of counters 91 or 92. At the completion of process of one block a dot area deciding circuit 10 compares each value of counters 91 and 92 with a prescribed value and when both values are greater than the prescribed value, it outputs a signal that is the dot area to a decision result output terminal 11.
