Title: Pulse doppler radar
Inventor: KURIHARA NOBORU
IPC: G01S13/64
Filed: 1982-09-09
Abstract: PURPOSE:To enable the production of a DF output equivalent in the characteristic to a high speed Fourier transformer output of 2N point simply by arranging a register and an adder between the number N of DF outputs of a high speed Fourier transformer and an amplitude detector to add the number N of DF outputs twice. CONSTITUTION:A received signal digitally converted with a receiver 3 is sent to a digital signal processor 4 and then to amplitude weighting circuit 6 to make a Doppler filter (DF) of a low side lobe characteristic via a clutter removing filter 5. Then, a frequency analysis is performed with a N point high speed Fourier transformer to obtain the number N of DF outputs in the output form of 1/Q2CH. An adder 15 adds data of registers A13 and A14 at each 1/Q2CH of DPs. These digital signal processing produces a DF characteristic equivalent to that of a 2N point high speed Fourier transformer thereby improving frequency resolution, identifying property of signals and clutter removing capacity substantially.

Title: Magnetic disk device
Inventor: NISHIMURA MAKOTO
IPC: G11B5/55
Filed: 1989-06-20
Abstract: PURPOSE:To accurately control the speed of a magnetic head and to quickly position the magnetic head by increasing a speed signal and a target speed signal K-number of times at the time when the distance from the position of the magnetic head to a target position reaches a preliminarily set residual extent of movement in the seek operation. CONSTITUTION:Servo information SI on a disk 1 is read by a magnetic head 3, and the speed signal indicating the movement speed of the magnetic head 3 is generated by a speed signal generating circuit 15, and the speed signal is amplified by gain control means 25 and 26 and is outputted. A central processing unit 13 outputs a speed command value at the time of moving the magnetic head 3 to the target position; and when the distance from the present position of the magnetic head 3 to the target position reaches a preliminarily set residual extent N of movement, the unit 13 increases the speed command value K-number of times (K>1) and outputs a control signal to gain control means 25 and 26. When the control signal is supplied to a gain control means 27, the gain is switched to K-fold gain. Thus, the speed of the magnetic head 3 is accurately controlled to quickly position the magnetic head 3.

Title: Ovecurrent detection circuit
Inventor: KATO AKIHIKO
IPC: H04N5/68
Filed: 1992-06-17
Abstract: PURPOSE:To detect all overcurrent of each voltage line at the secondary side of a switching transformer with a transistor(TR) having a low breakdown voltage by connecting an overcurrent detection circuit to an earth line. CONSTITUTION:When a fault takes place in a load at a secondary side of a switching transformer 1 and an overcurrent flows to a 100V or 15V output, the current returns to the switching transformer 1 through an earth line from the switching transformer 1. Even when an overcurrent flows to either of a 100V output and a 15V output line, the overcurrent is detected by connecting an overcurrent detection circuit comprising resistors 10-13, an electrolytic capacitor 14 and a TR 15 to the earth line. Furthermore, since the TR 15 for detecting the overcurrent is connected to the earth line, the TR 15 with a low breakdown voltage is enough and the cost is reduced.

Abstract: PROBLEM TO BE SOLVED: To heighten oil film formation force, secure long time low friction and small wear characteristics, and improve durability by forming many very small recessed parts on the sliding surface of a shaft part to improve the oil retaining capability on the sliding part. SOLUTION: The bearing surface 5a of a slide bearing 5 is opposite to the sliding surface 3a of a shaft part 3 through very small bearing clearances, and when the shaft part 3 is rotated, slip is caused between the bearing surface 5a and the sliding surface 3a. Many very small recessed parts are formed on the sliding surface 3a of the shaft part 3 to form independent recessed parts, and distributed at random on the sliding surface 3a. The outside of the very small recessed parts are formed in a smooth even surface. Surface working for obtaining the roughened surface condition of the sliding surface 3a can attain a desired finished surface by special barrel polishing. Thus, the oil film formation rate in the sliding part can be improved so as to reduce sliding resistance, and obtain sliding characteristics stably for a long time.
