IPC: H04N9/87
Filed: 1988-09-16
Abstract: PURPOSE:To prevent an incorrectable error from occurring in digital data and to obtain a desired video by selectively operating a drop out compensating means, a signal processing means, and a waveform arranging means. CONSTITUTION:When the output command of the digital data is issued, a signal of low level is outputted from a system controller 15, and the output of a pulse waveform arranging circuit 10 is selectively outputted from a change-over switch 21, and also, no drop out detecting signal is outputted from an AND gate 22. Therefore, the replacement of the digital data by data of 1H before is not performed even when the drop out occurs, which enables correction to be performed. Also, it is possible to prevent a waveform from deteriorating, and to reduce a read error rate. When no output instruction of the digital data is issued, drop out correction is performed, and also, a video format signal via a hue correction circuit 11 and a noise reduction circuit 13 is selectively outputted.

IPC: C04B35/65
Filed: 1987-09-16
Abstract: There is disclosed a method of producing a self-supporting ceramic composite body having therein at least one cavity which inversely replicates the geometry of an expendable pattern (6). The method includes the steps of surrounding the expendable pattern (6) with a filler material (4) to thereby form a filled cavity within the filler material (4). The expendable pattern (6) is chemically or physically removed from the filler material (4) and a quantity of a parent metal is put into the cavity. The parent metal is heated to a temperature above its melting point and an oxidation reaction process begins whereby the oxidation reaction product infiltrates and embeds the surrounding filler material (4). Excess filler material and/or excess parent metal are removed, thus resulting in a self-supporting ceramic composite body having a cavity in the shape of the expendable pattern (6).

IPC: H02P7/282
Filed: 1984-11-06
Abstract: PURPOSE:To prevent an armature voltage from becoming an overvoltage at field strengthening time by limiting a field current so that the counterelectromotive force of a DC motor does not exceed a rated voltage. CONSTITUTION:A field calculator 7 compares a speed feedback signal N with a speed reference signal N* to output a field control signal. A comparison discriminator 23 compares a speed reference signal before altering with a speed reference signal after altering, and switches a switch circuit 24 so as to become a speed reference difference to increase the field strengthening. Thus, a ramp signal for limiting the field current so that a counterelectromotive force from a field limit signal generator 25 does not exceed a rated voltage is output. Thus, it can prevent the counterelectromotive force from abnormally rising.

Title: Execution right transfer control system
Inventor: MIZUGUCHI TAMOTSU
IPC: G06F12/14
Filed: 1987-09-17
Abstract: PURPOSE:To transfer execution right from a higher privileged level to a lower privileged level by artificially performing command CALL execution procedures by a stack contents setting means and performing execution right transfer procedures by a command IRET. CONSTITUTION:Application 7 uses a command CALL to request the read of a file, which is stored on a floppy 20, to a fundamental software OS kernel 10. The kernel 10 analyzes it to judge that file management 6 should read this file. The kernel 10 sets three parameters to a parameter delivery buffer 5 and transfers the execution right to management 6. Management 6 receives parameters from the buffer 5 and reads out data corresponding to a designated side of the designated file from the floppy 20 to a buffer memory 30 and returns the control to the kernel 10. A command IRET start part 2 in the kernel 10 issues a command to restart execution of application 7. Thus, the execution right is transferred from a higher privileged level to a lower privileged level.
