Title: Image pickup tube
Inventor: ISHIYAMA KUNIO
IPC: H01J29/82
Filed: 1981-07-10
Abstract: PURPOSE:To provide an image pickup tube which has no characteristic variations and has a high reliability by supporting an electron gun so that any axial shift of the electron gun in an outer case doesn't develop even when there caused a thermal expansion of the electron gun. CONSTITUTION:The end of a rod 1, which is fixed to a stem 7, is fixed to a lower part 2a of a G3 electrode 2 by welding. Therefore, when the temperatures of a G1 electrode 5 and a G2 electrode 6 increase due to temperature rise of a cathode 4 caused by heating the cathode 4 by feeding a current to a heater 3, the electrodes 5 and 6 undergo thermal expansion and expand toward a stem 7. Here, the electrical connection between the electrodes 5 and 6 is achieved by use of a ribbon member in order to absorb the expansions of the electrodes 5 and 6. Owing to the above constitution, the degree of the shift toward a target 8 of the whole electron gun becomes extremely small. Besides, the temperature rise of a part, which extends from the lower part 2a of the G3 electrode 2 to the target 8, can be made below 1/10 the temperature rise of a part around the G1 electrode 5.

Title: Protection circuit for semiconductor laser
Inventor: HIKITA TSUTOMU
IPC: H01S5/068
Filed: 1982-06-21
Abstract: PURPOSE:To prevent the flow of overcurrent to a semiconductor laser at the time of superposition of amplitude noises or surges by a method wherein a Zener diode having a fixed Zener voltage is connected to the base of a laser drive transistor. CONSTITUTION:The semiconductor laser 2 is connected to the collector circuit of the transistor TR1, and then the semiconductor layer 2 is driven at a constant output by connecting the base of the TR1 to the constant voltage EB. For the purpose of protection of the laser 2 in such a circuit, the Zener diode 4 is connected to the base of the TR1. The Zener voltage VE of this diode 4 is designed approximately equal to the constant voltage EB. By such a circuit, when noises or surges superpose on the base voltage EB, and then the value exceeds VE, the excess part thereof is absorbed to the diode 4. Therefore, the flow of overcurrent to the semiconductor laser can be prevented at the time of superposition of amplitude noises of surges.

Filed: 1990-04-23
Abstract: PURPOSE:To reduce the cost of a terminal station by providing a variable rate coding section and a rate control section setting a coding rate of a coding section with a rate fixed setting signal inputted externally in the encoder of the terminal station equipment connecting to an STM and an ATM especially. CONSTITUTION:The transmission side of a CODEC (coder/decoder) is provided with a variable rate coding section 14a, a rate control section 22 and a cell composition section 26, and the reception side is provided with a cell decomposing section 28 and a decoding section 34. A variable rate CODEC applies variable rate coding to an input signal and the cell composing section 26 processes the input signal into a cell and sends the resulting cell. The cell decomposing section 28 at the reception side decomposes the cell and the decoding section 34 decodes the cell. When a rate fixing setting signal S1 is inputted to the rate control section 22 to fix the coding rate. The output of the coding section 14a is extracted not through the cell composing section 26 ((a) is its output signal) and the result is processed as an STM signal. An STM signal in the STM of the reception side is inputted directly through a switch 32 from an input terminal (b) to the decoding section 34, where the signal is decoded. Thus, the system copes with both STM and the ATM.
