IPC: G06K9/22
Filed: 1984-02-27
Abstract: PURPOSE:To discriminate also the information of a character or the like having the large dispersion of printing density correctly by changing a threshold in each scanning period of an image sensor and binary-coding a detecting signal. CONSTITUTION:Paper 3 is lighted by a lamp 4, the reflected light is formed on the photodetecting surface of an image sensor 6 through a lens system 5, the image sensor 6 outputs an electric signal corresponding to the brightness of each point of the paper surface and the output signal is amplified by an amplifier 7. A signal from the amplifier 7 is sent to a binary-coding circuit 11 and also a constant generating circuit 12 and the circuit 11 determines a threshold C' from the peak value A of a black level of the signal and the peak value B of the white level. Namely, C'=(A+B)/x is determined when x is regarded as a variable. The constant generating circuit 12 changes the constant corresponding to the variable x and sends the value to the binary-coding circuit 11 every scanning period of the image sensor 6 and the circuit 11 changes the threshold C in accordance with the value x to binary-code the signal from the amplifier 7. Even if the printing density has dispersion, correct binary-coding can be attained by several scanning.

Title: Low temperature metal gasket
Inventor: SUZUKI HIDEAKI
IPC: C22C9/01
Filed: 1979-03-30
Abstract: PURPOSE: To obtain metal gasket which can be repeatedly used and has a high sealing capacity against the facing frange surface by utilizing the shape memorizing effect of a metal with thermoelastic type martensite transformation chracteristic at the temperature below the room temperature.  
     CONSTITUTION: The alloy with thermo-plastic type martensite transformation characteristic possesses the shape memorizing effect by which it transforms at low stress, and furthermore, recovers its original shape completely by applying appropriate temperature. For this particular reason, the alloy is used to manufacture the metal gasket. Since twinning transformation and shifting of the interface between sister crystal grains within the thermoplastic type martensite phase are effected at low stress, they get to fit each other and seal well without applying large fastening force. Also, once the apparatus is used, only by heating, the shape completely recovers its original shape before the second use so that it can be repeatedly used.
