Title: Servo system for optical disk
Inventor: TAMARU NAOYUKI
IPC: G11B7/09
Filed: 1988-04-15
Abstract: PURPOSE:To eliminate a blind zone from the detecting output of tracking dislocation and to linearly change a tracking dislocation quantity near 0 by separating a tracking dislocation detecting mark from a track center by a fixed distance. CONSTITUTION:A tracking dislocation detecting mark 2 is arranged by separating it from a track center l by a fixed distance L. Consequently, when a head which is extremely sensitive to the reflection light quantity of a medium such as a compound resonant type head is used, the decrease of tracking servo control performance due to the generation of the blind zone is eliminated. Thus, the sensitivity of the tracking dislocation quantity becomes maximum near 0, a tracking dislocation detecting characteristic at excellent linearity can be obtained, and the stable tracking servo can be obtained.

Title: Migration method for ionized air and device therefor
Inventor: SAKUMA MANABU
IPC: H05F3/04
Filed: 1993-04-19
Abstract: PURPOSE:To allow the proper separation of ions over a relatively long time by independently migrating separated positive ions and negative ions. CONSTITUTION:A duct 11 has an air flow inlet 11a at one side and a forked branch section at the other side. One section of the branch is used as a positive ion duct 11b, while the other is used as a negative ion duct 11c. Also, an ion generator 15 is laid downstream of the inlet 11a. A coil 17 for causing the action of magnetic field B to separate positive and negative ions from each other is laid downstream of the ion generator 15 in the duct 11. In other words, when the magnetic field B is generated along a direction orthogonal with an air flow, positive ions are separated to come to the side of the positive ion duct 11b and negative ions are separated to come to the side of the negative ion duct 11c. Then, the positive and negative ions so separated are blown in the vicinity of a semiconductor substrate or the like via the ducts 11b and 11c.

Abstract: PURPOSE: To prevent the reverse rotation of a diesel engine and improve its starting characteristic, by performing the supply of fuel to the engine in accordance with the detection of rotational speed and oil pressure not less than a certain level with a use of rotational speed sensor and oil pressure sensor for the engine.  
     CONSTITUTION: Interlocking to a diesel engine 10, an oil pressure pump 16 is driven through a shaft 18. To the shaft 18 and the pump 16, a rotational speed detecting switch 28 turned on by a rotational speed sensor 26 at a rotation not less than an idling speed and an oil pressure switch 20 turned on at an oil pressure not less than a certain level are electrically connected. Then both signals are input to a control circuit 22 to simultaneously energize an actuator 24 at a generation of rotational speed and oil pressure not less than a certain level, and enable the supply of fuel to the engine 10 from a fuel infection pump 14. If the engine is reversely rotated, the actuator comes to an unenergized state at that point because the oil pressure is reduced.

Filed: 1981-06-17
Abstract: PURPOSE:To obtain an output analog signal with less distortion and dynamic range to the same degree as those of a D/A converter with good accuracy, by using a D/A converter less in the accuracy. CONSTITUTION:An input digital signal in n-bit from an input terminal 17 is applied to a digital adder 20, the adder 20 adds a constant digital code to the input digital signal and applies the digital signal after addition to a D/A converter 19.

Title: Magneto-optics device
Inventor: IWAOKA HIDETO
IPC: G02F1/09
Filed: 1983-05-27
Abstract: PURPOSE:To measure a current, magnetic flux, etc. with high resolution by dispersing the light projected from a Faraday effect element into two directions, receiving each separated light through an analyser and processing a signal from the photodetector. CONSTITUTION:The light from a laser light source 1 is turned to straight polarized light through a polarizing plate 2 and is made incident to the Faraday effect element 3. The light outputted from the element 3 is separated into two directions by half mirrors 71, 72 respectively and the separated light rays are transduced into electric signals e3, e1, e2 by photodetectors 51, 52 respectively through a photodetector 53 and analysers 41, 42. The signal e3 from the photodetector 53 corresponds to the intensity of the laser light source 1 or the change of the transmission efficiency of an optical transmission line. If the signal e3 is reduced less than said signals e1, e2 by subtracting circuits 81, 82, the influence due to the change of the laser light source 1 or the like is removed. An operation circuit 90 calculates the size of the current I. Thus, the current, magnetic flux, etc. can be measured with high resolution without the affect due to the variation of laser light source power.

Abstract: PROBLEM TO BE SOLVED: To simultaneously monitor a real-time output and a delayed output in simple configuration at low cost by displaying the real-time output in one field of one frame and displaying the delayed output in the other frame. SOLUTION: An object to be monitored is photographed by an image pickup part 10 of a television camera, the real-time output is supplied to the 1st field of the frame, and the output delayed by just a prescribed seconds by a delay circuit 6 is supplied to the 2nd field. Switching at such a time is performed for every prescribed fields by a switch circuit 11 synchronously with the clock signal of the image pickup part 10. In this case, concerning the real-time output and the delayed output, signal omitted fields are respectively interpolated by interpolation circuits 9R and 9D and picture quality is prevented from being lowered. Thus, the real-time output and the delayed output can be simultaneously monitored while reducing installation costs and hardware quantity, and the delay circuit is built in the same casing as the camera so that the configuration can be simplified.

Abstract: PURPOSE: To improve the productivity at the friction pressure welding by parallel performing deburring at the time of performing upsetting by rotating both works at high and low speeds respectively under axial thrust to cause frictional evolution of heat then making the speeds thereof low and equal.  
     CONSTITUTION: The works 6a, 6b are respectively inserted into the chucks 2, 3 revolving at a low speed and are gripped by gripping jaws 4, 5, after which the revolutions of the chuck 3 are shifted to a high speed and the chuck 2 is advanced toward the chuck 3 to cause frictional contact between the two works 6a, 6b under axial thrust, thereby evolving heat. Next, the pole change motor driving the chuck 3 is changed over to lower the speed of the chuck 3. When the rotating speed of the chuck 3 lowers and becomes equal to that of the chuck 2 or before this, the gripping jaws 5 of the chuck 3 are released to make the two work pieces 6a, 6b rotatable integrally. In this state, the axial thrust equal to or more than the above-described axial thrust is maintained for a while and upsetting is performed.
