Abstract: PURPOSE:To offer a title brightness switching circuit suitable for miniaturization of a home video camera by constituting a signal selecting a white character and a color character with a binary signal of high and low levels and using the signal as a title brightness switching signal. CONSTITUTION:Input signals at input terminals 7, 8 are inputted to an AND gate 5 at the same time and (1) level is outputted to the selection of white color and (0) level is outputted to the selection of red/green/blue color from the AND gate 5. This signal is inputted to a luminance signal setting circuit 6 to control it in correspondence to (1) and (0) and the brightness signal level of the white level and the red/green/blue level lower than the white level in the brightness is set. Then a title signal is synthesized by superimposing a chrominance carrier on a DC potential at a title signal synthesis circuit 2, and the title signal is added to the video signal by a color title adder circuit 3. Thus, the bright signal level for the white character and the color character is switched easily in this way.

Title: In-can pressure inspection device
Inventor: NOMURA TOSHIHIDE
IPC: G01L11/00
Filed: 1988-04-05
Abstract: PURPOSE:To accurately take a measurement without flawing a can body by passing a fixed pressure part and a presser body which is at a distance of size smaller than the external diameter of a can against the energizing force of the presser body while rolling the can. CONSTITUTION:The outer peripheral parts of presser bodies 17a and 17b are positioned at the shoulder part B and can body C of the can A respectively so that the distance to the surface of an endless belt (fixed pressure part) 8 is shorter than the minimum external diameter D of the can body C, and they are energized toward the can A with constant force set for air cylinders 10a and 10b. When the can A passes, the presser bodies 17a and 17b move against the energizing force. The energizing force of the pressure body 17a is weak, so the shoulder part B is not deformed, but the presser body 17b is pressed in the can body C with the energizing force. Here, the relative positions of both presser bodies are measured by an eddy current distance sensor, etc., to calculate the quantity of depression of the presser body 17b. This value is converted by electric computation into a numeral correlated to the internal pressure of the can A and when the numeral deviates from a set range, the can is judged to be a defective and then rejected by warning, etc.
