Title: Navigation apparatus
Inventor: ARIYOSHI HIRONOBU
IPC: G01C17/38
Filed: 1992-02-03
Abstract: PURPOSE:To securely compensate magnetization of a geomagnetic sensor by calculating a center point for a rotating circle obtained by combining two-axis output components of the geomagnetic sensor during its rotation from three or more sets of two axis output components obtained when the sensor rotates by a predetermined angle or more and compensating magnetization of the geomagnetic sensor output with the two axis output components corresponding to the center point as magnetism due to an external disturbance. CONSTITUTION:Three ring buffers 15, 16, 17 are connected to a central processor, while the buffer 15 stores thirty sets of two-axis output components obtained from a geomagnetic sensor 2, and the buffer 16 stores three sets of two-axis output components obtained by static processing with three linearly advancing paths with directions differing by 80 degrees or more, respectively, and a center point candidate is calculated from the three sets to be stored in the buffer 17. This processing is repeated and when three center point candidates are stored in the buffer 17, the data is averaged to obtain the center point of a rotating circle. Thus a statistically reliable center point can be obtained, permitting secure compensation of magnetization.

Title: Rake device for dust remover
Inventor: SAKOTA SUEHIRO
IPC: E02B5/08
Filed: 1983-02-04
Abstract: PURPOSE:To prevent the application of high loads on a rake by a method in which the rake is rotatably attached to the rake supporter in a horizontal axis turnable manner and the lower end of the rake is made up to press on a screen. CONSTITUTION:When a rake 40 is ready to rake up an excess of dregs 6, a spring box 34 and a truck 33 are pulled by a wire rope 45 and raised. Since the rake 40 is stopped by the dregs 6, the upper end portion 50 of the rake 40 is relatively moved to below the spring box 34, and then the rake 40 turns around a pin 41 and its lower end is moved to the direction of separating from a screen 5. If the size of the dregs 6 is within the height of the rake separated from the screen 5, the rake 40 can go over the dregs 6 and therefore, the application of excessive loads on the rake 40 can be prevented.

Title: Interrupt processing system
Inventor: YASUTAKE KUNIO
IPC: G06F15/02
Filed: 1979-02-19
Abstract: PURPOSE: To make it possible to perform an interrupt process during an arithmetic process when an interrupt of key input, etc., is caused while the arithmetic process is in process, by equipping an address control part with two incorporated buffer registers.  
     CONSTITUTION: If an interrupt of key-20 input would be caused during the execution of an arithmetic process, the input is detected through hardware using chattering preventive circuit 22 and one-shot circuit 26, and key processing start signal KIN is inputted to address control part 15. In this case, address control part 15 stores temporarily the next address of a main routine, where the arithmetic process is under way, in an incorporated address-assigning buffer register. Then, an address for key-20 input processing is outputted via another buffer register. As a result, the key-20 input processing starts since a micro-instruction for the key-20 input processing is assigned in control part 11.

Abstract: PURPOSE:To eliminate the error in adjusting an output level and to reduce the trouble in reproducing operation by deciding the maximum and minimum outputs in the various kinds of signals recorded in advance on a recording medium and by automatically adjusting the output level of the signal to be reproduced based on the deciding result thereof. CONSTITUTION:The level signal recorded on a space part 3 is reproduced prior to the starting of the reproduction of each sound recording part 2 and this level signal is inputted into a detecting circuit 6 and deciding circuit 8. The detecting circuit 6 gives its detecting signal to the deciding circuit 8, which decides the maximum and minimum outputs given by the level signal and outputs the deciding result as a gain setting signal to an amplifier 10 via a switching circuit 14, so the gain of the amplifier 10 is initially set in the prescribed value corresponding to the deciding signal. The signal reproduced by the sound recording part 2 in succession is inputted into the amplifier 10 via the 1st switching circuit accordingly and the since this input signal gain is initially set already the signal which passed through the amplifier 10 is automatically adjusted in optimum volume without causing any torsion.
