Title: Picture quality correction circuit
Inventor: ITO MASATERU
IPC: H04N5/208
Filed: 1986-11-26
Abstract: PURPOSE:To correct the picture quality sufficiently at a bright screen without deteriorating the S/N at a dark screen by inserting a nonlinear amplifier circuit having a higher gain as the APL is higher to a pre-stage of a picture quality correction signal generating circuit. CONSTITUTION:A nonlinear amplifier circuit 12 is inserted to the prestage of the picture quality signal generating circuit 4. The nonlinear amplifier circuit 12 has a higher gain as the average picture quality level (APL) is high in the signal and a video signal output 13 outputted from the nonlinear amplifier circuit 12 is inputted to a resistor R2 connected to a base of a transistor T6 of the picture quality correction signal generating circuit 4. Since the signal waveform of the video signal output 13 is obtained through the nonlinear amplifier circuit 12, a high APL is obtained in the picture quality correction signal 10 obtained at the output terminal of the picture quality correction signal generating circuit 4. That is, the correction signal is increased for the brighter signal. The picture quality correction signal 10 is fed to the synthesis circuit 7 via the DC gain control section 5 to be synthesized with the video signal 9 through a delay circuit 11.

Title: Apparatus for measuring liquid nature
Inventor: TOTOKI TOSHIO
IPC: C02F11/14
Filed: 1990-10-22
Abstract: PURPOSE:To perform highly sensitive measurement even if bubbles are generated by providing a heat wire for detecting thermal transfer which is linearly extended in contact with liquid inside a hollow tube in which the liquid is made flow. CONSTITUTION:A cylindrical hollow tube 2 comprises a naked metal wire 3 mainly composed of Au or Pt for example or the metal wire 3 made of Ni or W with heat-resisting and waterproof coating applied on a surface or the wire material, which is linearly extended to be in contact with liquid in the tube 2. While constant current is supplied to the metal wire (heat wire) 3 and also liquid (for example filtered liquid) is made to flow to be at a constant flow rate in the tube 2, the liquid nature is measured by measuring voltage across the heat wire 3. Since the heat wire 3 is linearly extended and its surface area is extremely small, measuring under high temperature conditions allows bubbles, if generated on the surface of the heat wire 3, to be released from the heat wire 3 immediately. In addition, since the surface area is small, attachment of contamination and dust can be minimized. As a result, stable measurement sensitivity can be obtained.

IPC: H01L21/203
Filed: 1987-11-12
Abstract: PURPOSE:To form a low temperature growth layer of good quality by vapor- depositing group III and V elements alternately in the case of an AlxAGa1-xAs growth onto a GaAs substrate of a (111) B face direction or a (111) A face direction. CONSTITUTION:In the case of an AlxGa1-xAs (x=0-1) epitaxial growth onto a GaAs substrate of a (111) B face direction of a (111) A face direction, the migration of a group III element is carried out in a large way by vapor- depositing group III and V elements alternately by using a molecular beam epitaxial growth. It is preferable for one vapor-depositing time (ON time) of a group III element to take a time for forming a vapor-depositing layer of a molecular layer or less and for a group V element to take a time for forming the vapor depositing layer of a molecular layer or more. The group III element perform migration not as an element of AlGaAs but as the element of Al and Ga. As the amount of migration in the case of single element is exceedingly larger than that of combined elements, two-dimensional growth can be performed and then, a growth layer exhibiting an excellent property of flatness is formed. In this way, a low temperature epitaxial layer of good quality is obtained without holding OFF-angles.
