Title: Film semiconductor device
Inventor: SHIMADA NAOYUKI
IPC: H01L27/12
Filed: 1990-11-30
Abstract: PURPOSE:To suppress the leak current even to the high voltage between a source and a drain and maintain great off resistance by making the gate electrode of, at least, one type of film transistor element have a plurality of gate electrode arranged apart in the longitudinal direction of a channel. CONSTITUTION:Between a pair of TFTs, which constitute a CMOS inverter, the gate electrode 7 of the n-type TFT 5 is divided in two, and the divided parts 7a and 7b are arranged apart in the longitudinal direction of a channel. By dividing the gate electrode and the channel region in twos, the voltage between a source and a drain is shouldered by approximately halves by two junctions. In this case, the voltage applied to one junction is halved, so the leak current flowing in the junction drops. This way, the resistance drop of the junction comes to be prevented, and as a whole, it can maintain great off resistance.

IPC: H01P1/205
Filed: 1992-12-21
Abstract: PURPOSE:To miniaturize the size of a printed circuit board for a filter by making a terminal pin arranged to a coaxial dielectric resonator also serve as an inductor connected in series to the coaxial dielectric resonator. CONSTITUTION:A terminal pin 11 for connecting the coaxial dielectric resonator 51 and a printed circuit board 52 of the dielectric filter which is serving also as an inductor is used. Concretely, the required inductance is secured by selecting the length of the terminal pin 11 to be sufficiently longer than that of a conventional pin. For example, let the length of the terminal pin 11 be 2.5mm, then the inductance of about 1.3n is obtained. Thus, a pad required to connect the inductor and the terminal pin in a conventional filter is not required and the size of the printed circuit board 52 is miniaturized. Furthermore, a pad used for terminal connection of a single plate capacitor 12 is not required and then the miniaturization is further attained.

Title: Data transfer method
Inventor: NOGUCHI SACHIHIRO
IPC: G06F5/06
Filed: 1992-12-22
Abstract: PURPOSE:To improve memory using efficiency and to prolong time of underflow by starting data transfer after a buffer is turned to a full state. CONSTITUTION:A video data generating circuit successively generates image data and supplies them to a dual port memory 10; The image data are successively written in the addresses of the dual port memory 10 instructed by a counter 23. When the image data are written up to the most significant address of the dual port memory 10, the coincidence signal of level ON is outputted from a comparator 25. At the point of time when the dual port memory 10 becomes full, namely, when initial processing is completed, the data generating circuit stops temporarily the operation and afterwards, reading on the dual port memory 10 is enabled. Since data transfer is started after the buffer is turned to the full state, the memory using efficiency is improved.

Title: Gate turn-off thyristor
Inventor: MATSUYOSHI SATOSHI
IPC: H01L29/74
Filed: 1991-12-25
Abstract: PURPOSE:To compensate influence of a delay of turning OFF due to a resistance of a gate electrode and to increase a controllable current without reducing an effective area of a cathode by reducing a current amplification factor of a transistor as it separates from a connecting position of an external gate electrode and shortening a turn-OFF time of a unit element.

Thus, when a resistance of the gate electrode is reduced to '0', a part far from the connecting position of the electrode is turned OFF therefrom, and the connecting position of the electrode is finally turned OFF. Accordingly, influence of a delay of turning OFF due to the resistance of the electrode can be compensated.

Title: Release and build-in management system for many terminal equipments
Inventor: KUGIMIYA TOSHIAKI
IPC: G06F9/06
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To reduce the working load by controlling the build-in timing of a module to be released after monitoring via every terminal equipment whether the build-in timing is executed in each module group. SOLUTION: The module to be released from a center computer 10 and a release module management file are distributed to a terminal equipment 20. A release build-in processing means C reads a management file 21 and confirms the version of the module of a release module work area 22 based on the group information of the release module. Then the means C refers to a module group state table 24 to wait until the end of the current module group if this group is under execution and then inhibits the start of the module group if the module group is not under execution to save the current release module to a backup area. Then the module group is reset at an executable state when the build-in is over for every release module group.
