Title: Knocking process for cathode-ray tube
Inventor: MUNEMOTO EIJI
IPC: H01J9/14
Filed: 1987-01-24
Abstract: PURPOSE:To make it possible to reduce generation of damage caused by a potential difference between a resistor and the inside wall surface of a neck part by fitting a ring body made of a resistance material on an outer circumference of the part in which an electron gun structure in the neck part is arranged. CONSTITUTION:A ring body 40 made of a resistance material is fitted on an outer circumference of the part in which an electron gun structure 9 in the neck part 8a of a cathode ray tube and the ring body is supplied with ground or low voltage. High voltage is impressed at least on one of plural electrodes in the electron gun structure 9 and the other electrodes adjacent to the electrode impressed by high voltage are supplied with ground or low voltage for performing knocking process to the cathode-ray tube. Accordingly, at the time of treating knocking, charged potential is lowered at the part opposed to the electron gun structure 9 on the inside wall surface of the neck part 8a of a tube body being affected by the ring body 40. Then, the potential on the surface of an insulating coating of a tube-inside resistor 7 is also lowered to reduce a potential difference to be applied to the insulating coating so as to prevent a change of resistance value of the resistor due to generated insulation deterioration or breaking of the insulation coating of the tube-inside resistor 7.

IPC: B41J35/10
Filed: 1979-02-10
Abstract: PURPOSE: To obtain an electronic typwriter having a simple circuit constitution without reducing the printing speed, by a method wherein, the time required for the selection of the character element is divided into groups in plural number, and the ink drive period corresponding to each group is set up.  
     CONSTITUTION: The ink ribbon is moved to the printing position while synchronizing it to the character selection mechanism, and in the electronic typewriter requiring a given time T 1  for the movement, the time required for the selection of the character element is divided into 3 groups of 0WTA(TA=T 1 ), TAWTB and TBW TC. TB is set to the value inbetween TA and TC. In case of the first group, the ink ribbon drive start time synchronizes with the start of the selection of the character element, whereas the ribbon drive time in the second and the third group is equivalent to the time when time T 1  is substracted from each time TB and time TC, that is, the setting is made to delay only each time TBD and time TCD from the time required for the selection of the character element.

Title: Mos type semiconductor device
Inventor: EZAKI TAKEYA
IPC: H01L29/78
Filed: 1983-01-31
Abstract: PURPOSE:To obtaina MOSFET, gains and outputs thereof are high in high- frequency and microwave frequency bands, by approximately bringing depletion layers extending to the outsides of a second conductive type channel regions into contact with a first conductive type intermediate drain region under a predetermined bias state. CONSTITUTION:Impurity concentration in an epitaxial layer 2 and distances among regions 5 and an intermediate drain 7 are selected so that depletion layers 11 are brought approximately into contact with the intermediate drain 7 under a bias state in which minimum drain voltage Vd=Vdsat for generating maximum drain currents is applied. Power gains largely depend upon feedback capacitance Cgd among gates 4 and a drain 1, and capacitance C2 among the gates 4 constituting capacitance Cgd and the epitaxial layer 2 sharply reduces until the depletion layers 11 reach the intermediate drain 7. Since feedback capacitance Cgd is small and the resistance rd of a path 12 is small extending over the whole region of Vd>Vdsat, large drain currents flow at low drain voltage, and high outputs are obtained.
