The characteristic quantity of a fold line expressing the relation between the output signal of the diode 435 and rotational angular velocity in fold line approximation is preliminarily stored in the memory 433 of a processing circuit 406. Then, the stored characteristic quantity of the fold line is adapted to the output signal of the diode 435 and operated by the circuit 436 to estimate rotational angular velocity output. By this method, the rotational angular velocity output can be calculated within a short time without operating inverse trigonometric function.

Title: Digital signal processor
Inventor: KUBO MASAFUMI
IPC: H04N7/081
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To prevent the output of images and voices which are inconvenient to a user by monitoring the change of the auxiliary data added to the signals of the recorded reproduction data of different formats. SOLUTION: The reproduction data which have undergone the error correction processing are divided into the video signals, audio signals and AUX data. Then the video and audio signals are sent a video signal holding/audio signal muting ON/OFF circuit 8, and the AUX data are transferred to a microcomputer 9 and also to a comparator 7. The comparator 7 compares the mode control signals received from the computer 9 with the mode signals contained in the AUX data. If the discordance is detected from the comparison, a discordance signal is supplied from the comparator 7 to the circuit 8 which holds the video signals acquired right before the discordance of AUX data is detected and also rewrites in real time the audio signals into the forced mute signals.

Title: Method of operating screw pump
Inventor: KAWAKAMI HIDETADA
IPC: F04B19/12
Filed: 1981-07-29
Abstract: PURPOSE:To enable to convey ready-mixed concrete or the like under pressure continuously without pulsation, by reciprocating the screw of a screw pump along the axis of its rotation, and controlling the turning speed and the reciprocating speed of the screw at the time of its forward stroke and backward stroke appropriately. CONSTITUTION:With ready-mixed concrete or the like charged in a hopper 3, a screw 6 is turned by a motor 8, and at the same time, it is reciprocated by a hydraulic cylinder means 10. Here, the turning speed and the reciprocating speed of the screw 6 are selected under specific conditions such that ready- mixed concrete is dischargeed always at a constant rate and without pulsation from a discharge port of a single-barrel screw pump. Thus, since the screw 6 is reciprocated while conveying concrete under pressure by the turning of the screw 6, it is enabled to prevent co-turning of the screw 6 and a fluid to be conveyed due to sticking of the fluid to the screw shaft section 4a and hence to convey the fluid under high pressure.
