Title: Electrode construction of discharge tube
Inventor: IWAI TOORU
IPC: H01J17/22
Filed: 1981-05-27
Abstract: PURPOSE:To improve the cooling effect of an electrode by enclosing the electrode, i.e., a charging section, with an insulating tube, fixing a radiator on the tip of the insulating tube, and transferring the heat of the electrode to the radiator by means of an operating liquid. CONSTITUTION:An electrode 1 which is fed with the electric power through a terminal 1a is erected in the inner space partitioned by a discharge tube wall 2 astride of a gap of the discharge tube wall 2, and is enclosed by an insulating tube 2a extending upward unilaterally. A radiator 3 made of metal has a radiating fin 3a, and is fixed to the tip of the insulating tube 2a. As a result, a sealed space 4 partitioned by the electrode 1, insulating tube 2a, and radiator 3 is formed, and an insulating operating liquid is sealed in this sealed space 4 so as to immerse the electrode 1. The operating liquid 5 evaporated by the heat of the electrode 1 is cooled by the radiator 3 and drops down.

Title: Perpendicular information writing device
Inventor: OYA TSUTOMU
IPC: H04N7/173
Filed: 1988-03-31
Abstract: PURPOSE:To reduce the burden of a microcomputer at the time of perpendicular hatching write by executing selectively write of dotted line data only in a write section of perpendicular information, based on dotted line width data. CONSTITUTION:A write section corresponding to length of a straight line of conventional linear write is obtained as a result of a rise of a writable signal and a count of length data. In case of executing write of dotted line data, a dotted line width port 25 to which ditted line width data corresponding to a value which has subtracted '1' from data length of one dotted line data is provided, and an output of this port 25 sets a count value to a dotted line width counter 26. In accordance with the dotted line width data which has been obtained in such a way, write of the dotted line data is executed only in a write section. In such a way, a decision processing in a start point and an end point of write, and a processing for deciding the end by the number of times of repetition of perpendicular hatching become unnecessary, and the burden of a microcomputer can be lightened.

Title: Beam current suppressing circuit of television receiver
Inventor: KITAMURA YOSHIHIRO
IPC: H04N5/14
Filed: 1983-05-07
Abstract: PURPOSE:To prevent characters displayed on a CRT from blurring by adding a circuit for current bypassing to a beam current suppressing circuit, and switching beam current suppression levels. CONSTITUTION:The different point as compared with a conventional circuit is that a transistor TRTR2, resistances R2, R3, and R4, and a voltage source E3 are added to the beam current suppressing circuit 3. Then, a current I2 is flowed to the TRTR2 to set a suppression current level I1 to [(E1-E2)/R1]-I2, and the current I2 is expressed in an equation I . Consequently, the large variable range of the current I2 and, therefore, a beam current I1 is obtained by small variation in voltage E3. For this purpose, a set voltage is held at ''0''V during TV broadcast reception to increase the suppression level, and held at a specific level during RGB reception to decrease the suppression level, thus preventing characters from blurring.
