Title: Control system for state record memory
Inventor: TONE HIROSADA
IPC: G06F12/06
Filed: 1984-02-29
Abstract: PURPOSE:To increase the number of cycles of a history state which can be stored without increasing the capacity of a history memory, etc., by dividing the history memory, etc. so that an access is possible for each prescribed area and storing the history states when necessary to those divided area in a circulating form. CONSTITUTION:In case the 1K MODE signal shown at the left end is not equal to an extension mode, an incrementer 15 supplies cyclically an address of an address register 14 to a history memory 11. While the prescribed history data is written to an area of one word and 64 bits forming the memory 11. Therefore the history data of 256 cycles is still stored in the memory 11 in case the rewriting of the history data is stopped to the memory 11. When the 1K MODE signal is equal to an extension mode, the incrementer supplies cyclically an address 0 or one of 255 addresses of an address register 14 to the memory 11. At the same time, a carry delivered from a bit 2 of the incrementer 15 is transmitted to a bit 1 and therefore functions as an incrementer having 10 bits.

Abstract: PURPOSE:To certainly supply getter in an amount enough to hold within a cathode ray tube at a high degree of vacuum for a long period of time, by sensing that amount of getter material which has been evaporated fast while the getter material is left to evaporative attachment process. CONSTITUTION:The input at starting of high frequency heating shall be set so that no excessive amount of getter material 4b will be attached evaporatively. When high frequency heating is commenced and the temp. of a getter vessel 4a has become approx. 800 deg.C, the heat emitting reaction begins in the getter material 4b, whose temp. will immediately rise to around 1300 deg.C. At the same time, the material 4b evaporates and attaches to the getter film thickness measuring part 6a where no interior electroconductive film 6 exists. The getter film thickness is measured by a film thickness sensor element 11, and on the basis of the result from measurement, the output of a high frequency power supply shall be controlled. Thereby the spouting of the getter material 4b can be performed so that excess or shortage in spouting the material 4b will be compensated. That is, the getter can be spouted in a proper amount for maintaining inside of the tube at a high degree of vacuum when the cathode ray tube is 10 practical service.

Filed: 1985-03-01
Abstract: PURPOSE:To enable to make the taper angle of a resin film pattern smaller than the conventional one by a method wherein the initial thickness of the film made of photosensitive polyimide is reduced. CONSTITUTION:Using photosensitive polyimide for a resin film 1, the thickness of the film before developing is thinly formed so that a pattern can be formed at the developing period approximately 1/4 or less of the ordinary developing period, and the amount of exposure is increased, thereby enabling to make small the taper angle of the pattern. For example, an Au pattern formed garnet wafer is used as a substrate 2, and a pattern is formed by performing (a) spin- coating of photosensitive polyimide, (b) prebaking, (c) exposing, (d) developing and (e) curing processes. As a result, the taper angle can be made smaller in the range of 3-20 deg., and the number of processes can be reduced to approximately one half of that of the conventional method wherein a resist is used.
