Title: Permanent magnet and its manufacture
Inventor: ISHIDA AKIRA
IPC: H01F1/057
Filed: 1990-07-06
Abstract: PURPOSE:To improve not only the magnetic characteristic of a permanent magnet formed by sintering alloy powder containing rare earth elements, but also the mechanical strength of the magnet so that it can stand super-high speed rotations by linking the alloy powder by sintering through a metallic thin film coating the powder. CONSTITUTION:Firstly, prescribed amounts of neodymium, ferroboron alloy of electrolytic iron and boron, and cobalt, all of which become magnet components, are mixed and subject to high-frequency melting or arc melting in an argon atmosphere. After the alloy thus obtained is crushed and ground into a particle size of about 250-mesh in an argon atmosphere, the particles are further ground into powder of about 3-4mum in particle size. Then a coating process is performed by plating by using an electroless plating liquid of iron, cobalt, nickel, or copper or of the combination of two or three of them. The magnetic powder is formed in a magnetic field of 12KOe in intensity under a pressure of 1.5ton/cm<2> and the formed body is sintered for 1-4 hours at 1,000-1,100 deg.C in an argon atmosphere. The sintered body is subject to an aging process for 2 hours at 600 deg.C and magnetization. Thus this permanent magnet is manufactured.

Title: Photoelectric conversion circuit for automatic focus detector
Inventor: IGUCHI SUSUMU
IPC: G03B13/36
Filed: 1990-07-09
Abstract: PURPOSE:To correctly compensate a picture signal by impressing a transfer pulse or another pulse synchronized to the transfer pulse upon a compensating reference signal generation circuit as a reset signal in a non-integrating period during which no electric charge is accumulated in an accumulation electrode. CONSTITUTION:A compensating reference signal generation circuit 26 is reset at the same timing and frequency as a picture signal output circuit 32 is reset by means of a transfer clock pulse 1 after the circuit 26 is substantially reset by means of a storage pulse ST immediately after a non-integrating period is started. In other words, the resetting condition of the circuit 26 is the same as that of the circuit 32. Since the circuit 26 is not reset during the non- integrating period when the circuit 26 is reset immediately after the non- integrating period is started, the occurrence of such a case that a compensating reference signal DOS changes as the time elapses and the changed amount of the signal DOS is added to a picture signal OS as an error at a picture signal processing circuit is completely eliminated. Therefore, the picture signal OS can be compensated appropriately.

Title: Tracking device
Inventor: KOBAYASHI MASAAKI
IPC: G05D3/12
Filed: 1981-11-09
Abstract: PURPOSE:To prolong the life of a head actuator when a bonded piezoelectric element is used for the head actuator, by setting the mean value of a signal waveform applied to the head actuator to zero. CONSTITUTION:To the terminal CONT of a delay circuit 52, 0V is applied firstly because a switch circuit SW is closed. A control signal reproduced by a control head 51 is frequency-divided by a frequency dividing circuit 58 and inputted to the terminal T of the delay circuit. This input signal is delayed by a delay time corresponding to the input 0V to the terminal CONT and then supplied to a phase comparing circuit 53. This circuit 53 is supplied with a phase reference signal and its output signal is supplied to a capstan motor 55 through a driving circuit 54. Consequently, a starting capstan phase control loop is formed. Thus, the SW is opened after a phase control system for a magnetic tape run is locked. Then, the voltage obtained by smoothing a scanning position correcting signal through a smoothing circuit 50 is applied to the circuit 52. Therefore, the control system operates so that a smoothed waveform is at about 0V.

Title: Rotation screw pulling method of multiple thread screw resin molded article
Inventor: TANIGUCHI TETSUO
IPC: B29C45/26
Filed: 1989-07-11
Abstract: PURPOSE:To prevent the occurrence of scratches, roughing and dimensional deterioration in a multiple thread screw, and make a guide screw bush unnecessary, and also reduce the cost by making the multiple thread screw and screw lead identical and arranging additionally an extra screw in which the screw pitching is larger and the effective screw length is also longer as compared with the multiple thread screw. CONSTITUTION:A resin molded article 1 is molded between an outer mold 10 and rotating core 4. When the resin mold article 1 is cooled and cured, a motor 9 is rotated and the rotating core 4 is driven via gears 7, 8. Since the extra screw 3 is larger in its thread size and higher in its rigidity than the multiple thread screw, the thrust loads during the pulling period are supported mainly by the extra screw 3. And, even at the pulling completion of the effective screw 2 in the multiple thread screw 2, the rotating core 4 has still been fitted in the extra screw 3, so that there is no fear that the excessive thrust loads are loaded on the cut-up part of the multiple thread part 2. At the completion in screw pulling of the screw 3, the cut-up part of the waste screw 3 is lightly deformed because thrust loads concentrate thereto, however, the multiple thread screw 2 has been passed therethrough, and thus there is no problem on the performance of the resin molded article.
