Title: Threshold correcting method
Inventor: KODERA MASAHIDE
IPC: H04N1/403
Filed: 1986-08-05
Abstract: PURPOSE:To alter a correction factor according to a relative resolution and to equalize the concentration of a copy by varying the correction factor of the threshold for reading the picture recorded on a film so as to quantize according to the contrast of the picture. CONSTITUTION:When the contrast value of the picture is small and small characters are set for a bit of picture information, one scale constant K is made smaller so as to make the correction factor small. And when the contrast value is large, such as the time large characters are for the bit of picture information, one scale constant K is made larger to make the correction factor large. For example, a threshold set part 4 uses a step value from a concentration set part 1 and the contrast value from a contrast detection part 2 so that it can set and output the threshold by using the correction factor according to the contrast value. Therefore as for both the picture with the large characters group of information and the picture with small characters group of information, the difference of the concentration per the one scale of a copy concentration adjustment scale can be equalized so as to properly adjust the concentration of the copy.

Title: Radiation shield
Inventor: NEMEZAWA ISAO
IPC: G21F3/00
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To facilitate the work for treating contamination in a radiation shield when radioactive substances adhere to it. SOLUTION: A coating material 3 is applied through a release agent to an irregular-shaped steel plate 2 as a radiation shield material for a radiation shield. Even if radioactive substances adheres to the irregular-shaped steel plate 2 coated in such a way, the adhesion reaches only the coating material 3 and radioactive substances are prevented from adhering to the irregular-shaped steel plate 2. The radioactive substances exfoliate the coating material 3 from the side of the irregular-shaped steel plate 2 and are removed together with the coating material 3. Consequently, the irregular-shaped steel plate 2 is recovered and recycled in a clean condition.  The release work can be carried out easily because the release agent is applied to the irregular-shaped steel plate 2 in advance, which facilitates the work for treating contamination when radioactive substances adhere to the radiation shield.

Title: Circuit for receiving infrared-ray pulse
Inventor: KIKUCHI MANABU
IPC: G01S7/48
Filed: 1983-10-05
Abstract: PURPOSE:To prevent the effect of the sunlight from being incurred by constituting the circuit that a primary winding of a pulse transformer and a photodetector are connected in series and an output signal is obtained from a secondary winding of the pulse transformer. CONSTITUTION:A cathode of a photodetector D3 receiving an infrared pulse ray l is connected to a terminal of a power supply voltage Vcc via a primary winding P of the pulse transformer T2. One end of the secondary winding S of the transformer T2 is connected to an output terminal OUT via a capacitor C3. The voltage Vcc reverse-biases the detector D3 via a winding P and an electric signal corresponding to the luminous amount change is obtained from the winding S via the capacitor C3. Through the constitution above, even if the sunlight is irradiated directly to the detector D3, the voltage drop due to the reverse bias current of the detector D3 and the DC resistance value of the transformer T2 is very small and the detectors D3 is not saturated. Moreover, the iron core of the transformer T2 is not saturated because of the reverse bias current of the detector D3. Thus, the effect of the sunlight is not caused.
