Title: Digital oscillator
Inventor: KIHARA KOICHI
IPC: H03B28/00
Filed: 1988-04-30
Abstract: PURPOSE:To produce a sine wave with a slight amount of memory capacity by using an initializing circuit and continuing the oscillation while substituting properly the initial value to a secondary IIR digital filter. CONSTITUTION:The title oscillator consists of secondary digital filter IIR digital filter A composing of unit delay elements 1 and 2, a multiplier 11 and an adder 7 and an initializing circuit B substituting the initial value to both elements 1 and 2. When a sine wave is produced, a recurrence formula of a trigonometrical function is used as shown in an equation I. That is, sin(0), sin(x) sin(2x)... can be successively obtained with application of the initial values, i.e., sin(-x) and sin(-2x). Thus the sine waves are oscillated. As a result, a slight amount of the data memory capacity suffices owing to application of an oscillation theory where a single frequency is produced by arithmetic.

Filed: 1989-04-27
Abstract: PURPOSE:To prevent the degradation of the product quality caused by the variation of an operational condition by generating static magnetic field to the whole zone to the lateral direction of a mold with magnetic poles disposed on the back faces of the facing side walls in the mold for continuous casting. CONSTITUTION:At the time of generating the static magnetic field to the whole zone to the lateral direction of the mold 1 with the magnetic poles 3 disposed on the back faces of the facing side walls in the continuously casting mold 1, the spout of the molten steel from a submerged nozzle 2 is caused to flow in the uniform magnetic field and the flowing velocity is reduced and the magnetic field serves as reflecting plate to the spout and the direction of the flow can be changed. Then, even if the operational condition of the discharging angle, the discharging velocity, etc., of the submerged nozzle is varied, the spout always goes to the uniform flow downward whose velocity is reduced. By this method, the reduction of the involution of mold powder and the invading depth of inclusion can be obtd.

Abstract: PURPOSE:To reduce the cost and to detect a focus state always stably with high accuracy by detecting a focus state with respect to an object receiving a light of a convergence optical system based on an output of a photodetector section of a light emitting element and a light receiving element. CONSTITUTION:A light from an LD 51 of a light receiving and light emitting element 31 is reflected in a translucent face (1st face) 33 of a photodetector element 32 and converged to an object 35 receiving a light such as an optical disk via an objective lens 38. Then grating is applied to the translucent face 35 of the photodetector element 32 and generated + or -1st diffracted lights are projected to the object 35 receiving a light via the objective lens 38. Thus, three spots comprising a main beam spot 36 of the 0-th diffracted light and sub beam spots 37a, 37b of the + or -1st diffracted lights are formed on the object 35 receiving a light. Thus, the position alignment of the photodetector section with respect to the light emitting section is not required, the cost is reduced and the focal state is always stably detected with high accuracy.

Title: Tone arm driving device
Inventor: HAYASHI HIDEAKI
IPC: G11B3/085
Filed: 1978-08-31
Abstract: PURPOSE: To drive the tone arm to a setting position at a stable speed by making the difference between the position detecting output of the tone arm and the setting standard voltage thereof a base voltage.  
     CONSTITUTION: The voltage (c) corresponding to the rotating speed of the arm 1 is obtained from the voltage of a center point a of the photo detection elements 6, 6' in which the resistance is differentially changed as the tone arm 1 rotates, namely the position detecting output. The voltage (b) and the voltage (a) obtained by dividing the direct current voltage by a variable resistance VR are added to the differential amplifier C to form the position setting base voltage (d). The base voltage (d) and the voltage (c) are supplied to differential amplifier B and the difference output drives the horizontal driving portion 3. In this manner, the movement of the arm 1 becoms slower it approaches to the seting position, and becomes faster when it is far therefrom and further smoother. If the resistance VR is made variable, the arm 1 can be moved at any position. Thus, the arm 1 can be moved to the setting position at a stable speed and relatively fast even for the change of load in the arm 1.

Title: Beacon receiving apparatus
Inventor: HIKOSOU KEIJI
IPC: G01S1/68
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain a beacon receiving apparatus by which the time when a vehicle is passed through the side of the transmission source of composite modulated waves can be judged precisely and quickly by a method, wherein a detection based on a cyclic redundancy code is performed for every detected data frame. SOLUTION: A phase judgment part 111 compares the phase of an AM demodulated signal to be output from an AM demodulation part with the phase of a reference clock signal, so as to judge whether the phase of an AM modulation component is identical to the phase of an FM modulation component. At this time, the output signal of a field-strength comparison part 110 is referred to. In the phase judgment part 111, a result by the comparison of the phase of the FM modulation component with that of the AM modulation component is judged for every data frame. At this time, when an error is generated in the detection of the data frame, the phase of an amplitude modulation with reference to the data frame is not used to judge the passage time near a transmission source based on its change.  There is no concern that the error in the detection of the data frame misleads the judgment of the passage time. Consequently, the passage time near the transmission source can always judged correctly, and the running position of a vehicle can be known correctly.
