Patent JP-S5697113-A (JP)
Title: Constant-voltage device for alternating current
Inventor: HASHIMOTO TOSHIO
IPC: G05F1/455
Filed: 1979-12-31
Abstract: PURPOSE: To keep constant the voltage given to the load, by controlling the phase of switching elements with ease externally, which are connected between the AC power input and the load.  
     CONSTITUTION: A variable resistor 32 is provided at an inverting input terminal of an error amplifier 6 via a resistor 31, and it is located outside the device to draw out the current I 0 . The amplifier 6 is an operational amplifier which has a nagative feedback circuit of RC in parallel connection, and the output V 3  is determined so that input voltage V 1 =V 2  can be obtained at steady-state. When the current I 0  flows, V 3  changes correspondingly, resulting in changing the AC output V 0 . Since V 0  changes in proportion to I 0 , the AC output V 0  can continuously be adjusted by externally adjusting I 0 . In this case, when the variable resistor 32 is selected to a sufficiently smaller value than the resistor 31, the current I 0 , that is, the AC output voltage V 0 , is almost in proportion to the set value of the variable resistor 32, the width of change in V 0  is determined with the resistor 31. Thus, even if the variable resistor 32 is in variation by ±20% or so, I 0  is not subject to any effect and the variable resistance can easily by replaced.

Title: Image recorder
Inventor: SASAHARA KENJI
IPC: G03G15/00
Filed: 1988-07-13
Abstract: PURPOSE:To enable a paper size to be correctly detected even when a sheet material is inserted askew into manual insertion port by conducting a first paper size detection action at the manual insertion port and a second paper size detection action after a fixed-amount sheet feed. CONSTITUTION:When recording paper 50 of A2 size is inserted askew into a manual insertion port, it cannot be detected by an A2-size sensor 45 because of its askew attitude. Thus, the recording paper 50 is judged to be of A3 size in a first paper size detection action. Thereafter, the recording paper 50 is taken up by a fixed amount by rotating a hand insertion roller 32, thereby being detected by the A2-size sensor 45. In this manner, the sheet material is judged to be askew. Alternatively, the paper size obtained in the first paper size detection action at the hand insertion port is compared with the paper size obtained in the second paper size detection action after the recording paper is taken up by the manual insertion roller 32, and if the both are not coincident, a warning that the recording paper should be reinserted can be issued on a display part.

IPC: H04N5/45
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To operate optimal gradation correction to each picture in a small circuit scale even when plural pictures are displayed on a display screen. SOLUTION: A luminance signal is converted into a digital signal by an A/D converter 1 for each field, and inputted through a histogram i/f circuit 3 to a histogram 2. The histogram 2 stores the degree of each luminance as data by using a luminance value as an address. A CPU 4 prepares the cumulative histogram of luminance based on the histogram data, and fetches it through a cumulative memory i/f circuit 9 in a cumulative histogram memory 8. The CPU 4 prepares correction data by referring to the result of the cumulative histogram for each screen so that the cumulative curve can be a straight line, and stores it in lookup table memories 11a and 11b. Thus, gradation correction can be operated by this table.

Therefore, even when the carrier moving degree or threshold voltage of both the P and N MOS transistors are dispersed on the manufacture, for example, the conditions of expressions III and IV are established and in the case of taup8 a. tauN7 and tauN10=taup10, tauN10=tauN11, tpdr= tpdf is realized. Accordingly, (tpdr-tpdf[ can be reduced, and the productivity can be improved.
