Title: Sos semiconductor base
Inventor: MIURA YOSHIO
IPC: H01L21/20
Filed: 1978-09-16
Abstract: PURPOSE: To protect the quality inferiority of heated sapphire by annealling the polycrystal Si-layer with argon laser, after the Si-layer is grown on the sapphire base at low temperature.  
     CONSTITUTION: After the polycrystal Si-layer 4 was grown on the sapphire base 3 at relatively low temperature of 600W700°C, the layer is annealled under a given condition with argon laser. Then, the Si-layer 4 is converted to a single crystal Si-layer 5 and a well crystalized SOS semiconductor base is obtained. By so doing, it is possible to protect the quality interiority caused by distortion etc. due to different thermal expansibility between sapphire and Si when the base 3 is heated up.

Filed: 1978-09-20
Abstract: PURPOSE: To ensure a correct identification for the reception data as well as to omit the coincidence between the delay time and the fluctuation of the delay time on the transmission line by transmitting both the data signal and the strobe signal in the form of the composite signal through the common transmission system.  
     CONSTITUTION: Composite signal H is produced at transmission side 10 by compounding data signal A and strobe signal B which is in a fixed relation to signal A. Signal H thus composed is then transmitted to transmission line 11 and received at the reception side through line 11 to extract 13 strobe signal E. Then strobe 14 is given to reception composite signal D via signal F obtained by giving delay 15 for a fixed time to signal E, thus giving the identification to data signal C. In this way, the reception data can be identified correctly, thus omitting the coincidence between the delay time and the fluctuation of the delay time on the transmission line.

Abstract: PURPOSE:To receive transmission signals even with a conventional receiver dedicated to frame image signals by transmitting one field image signals and generating one field image signals with interpolation signals, then transmitting them. CONSTITUTION:The image signal obtained by an image input part 19 is inputted to an A/D converter 21, where it is converted to a digital signal by sampling with a pulse outputted from a sampling pulse generator 20, to be inputted to a first field memory 22 and a second field memory 23, and is frozen by a control part 38. Where, the interpolation signal generated by an interpolation arithmetic unit 24 by calculating the output of the first field memory 22 is inputted to the second field memory 23 when a switch S1 is connected to (a) side terminal. But when the S1 is connected to a (b) side terminal, the output of the A/D converter 21 is directly inputted to the second field memory 23. That means that, when the switch S1 is connected to the (a) side terminal, the signal obtained by the image input part 19 is the field image information, and this is a case that the control part 38 selects the frame transmission. The output information from the memories 22 and 23 are controlled by a switch S2, and inputted to a CPU 26.

Title: Image pickup device
Inventor: TAKAYAMA TSUTOMU
IPC: H04N9/11
Filed: 1990-05-02
Abstract: PURPOSE:To accurately adjust white balance in any density area of a negative film by shifting the black level of a color signal by a specific quantity according to the operation of a reversal processing means when the reversal processing of the colors of plural color signals is performed. CONSTITUTION:Clamp potentials of R, G, and B in normal mode are all Vref, so when the negative film is signal-processed as a latent image positive image in this mode, respective signal levels of the colors R, G, and B are proportional to the film density, so the signal levels corresponding to, for example, an exposure quantity EO are VRO, VGO, and VBO and a deviation in white balance increases. In negative mode, on the other hand, VR or VB is supplied as the clamp potentials of the R or B signal and the black levels of the R signal and B signal are shifted by VGO - VRO and VGO - VBO respectively. Consequently, the respective output signal levels become equal when the exposure quantity is EO and the white balance is prevented from deviating.
