Title: Apparatus for detecting torque
Inventor: ITO TSUNEJI
IPC: F16H61/00
Filed: 1984-11-22
Abstract: PURPOSE:To accurately set a sampling cycle, by providing a position standard comprising a groove or projection to the torque detection part to an output shaft. CONSTITUTION:Because a groove 20 or projection is provided to the outer peripheral surface of the detection part of an output shaft 2, magnetic flux density largely changes when the groove 20 or projection is faced to a detector 9 and pulse output P is formed so as to exceed a preliminarily imparted threshold level S. The reference position of the output shaft 2 is cleared by this pulse output P and, therefore, for example, a sampling cycle corresponding to one cycle can be set on the basis of said pulse output and an average value MT can be obtained from plural sample values taken in the sampling cycle. Further, the number of rotations can be also detected from the formed pulse output P.

Title: Circuit board for camera
Inventor: MACHIDA KIYOSADA
IPC: G03B17/24
Filed: 1993-09-07
Abstract: PURPOSE:To surely reduce or intercept light entering from the gap between a circuit board and a cover case by cranking a mounted pattern at the joint part of the cover case on the circuit board. CONSTITUTION:The part 51a corresponding to the joint part 22 of the cover case 20, of patterns 51 formed on the rear of the circuit board 10 is cranked to form a maze, so that noise light from the direction of A passing through the gap between the mutually adjacent patterns 51 along the rear of the circuit board 10 and entering the cover case 20 can be surely intercepted. In other words, when the noise light enters the gap between the mutually adjacent patterns 51 and is made incident on the cranked parts 52 to 55 of the patterns 51 while the noise light passes through the cranked parts, the noise light is attenuated and extinguished without entering the cover case 20. Moreover, rays of noise light from the directions of B, C and D do not enter the cover case 20, because the cover case 20 is brought into close contact with patterns 46, 47 and 48, so that the exposure of a film can be prevented.

Title: Image forming device
Inventor: NISHIMURA TOSHIJI
IPC: G03B27/32
Filed: 1985-11-05
Abstract: PURPOSE:To relieve sheets without deciding the state as a paper jam even if these sheets are carried while overlapping partially, by deciding the paper jam if a sensor which monitors the paper jam of sheets detects sheets for a period longer than the sheet passage time corresponding to two sheets. CONSTITUTION:Even if the sensor is turned on for the total period (at a maximum) of a period corresponding to the size of a concerned sheet and that of a following sheet, it is not decided as the paper jam. Data of sizes and order of sheets detected by a sensor 21 or a sensor 25 is processed properly to easily obtain this constitution. That is, data of sizes and order are used to assign the period corresponding to the length of two continuous carried sheets to the sensor, which should detect the first sheet of overlapping sheets, as a maximum detection time. Thus, it is not decided as the paper jam when two sheets are carried while overlapping.

Title: Recording medium having magnetic layer and optical recording layer and its production
Inventor: RYOMO KATSUMI
IPC: G11B7/24067
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent the splashing of optical recording layer components, to improve the durability of a head and to enable a higher density and higher speed access by providing the surface of a base with an optical recording layer, an intermediate layer and a magnetic layer in this order. SOLUTION: This recording medium is provided with the optical recording layer, the intermediate layer and the magnetic layer in this order on the base. Recording and reproducing to and from the optical recording layer are executed through the base as the structure to hold the optical recording layer via the intermediate layer. Such layer constitution is produced by preparing coating materials for forming the respective layers and successively applying these coating materials on the base. More preferably, the formation of these coating materials at one time by a simultaneous double layer application system is made possible. The thickness of the magnetic layer is reduced to a small thickness by the simultaneous double layer application by disposing the intermediate layer between the magnetic layer and optical recording layer.  The recording medium may thus be provided with the uniform magnetic layer of <=0.5 μm in reproduction thickness loss. Since the magnetic layer may be formed thin in the manner described above, information signals are preferably recorded on the magnetic layer and servo signals on the optical recording layer.

Abstract: PURPOSE:To prevent servo response characteristics of a head from deteriorating due to a bias magnetic field by forming an electromagnetic force generating magnetic field for servo operation and the bias magnetic field in the direction of adding to each other in a recording and reproducing head and an erasing head. CONSTITUTION:The bias magnetic field for recording 40a, 40b by a magnet 40 for generating the bias magnetic field for recording generates magnetic flux passing vertically through a magneto-optical disk 2 from its upper surface to lower surface right under the magnet 40. On the other hand, a magnetic field 20aa, 20ba by an actuator magnet 20a, 20b and the magnetic field 40a, 40b are in the same direction as each other in the recording head 15. Consequently, in the head 15, the magnetic field with the magnet 20aa, 20ba cannot be canceled by the magnetic field with the magnet 40. On the other hand, in the erasing head 16, a magnetic field 41a, 41b by a magnet 41 for generating the bias magnetic field for erasing and an actuator magnet 30a, 30b are set respectively in the direction of adding to each other.
