Title: Detection of number of revolutions of brushless dc motor
Inventor: NOZU SEIICHI
IPC: G01D5/245
Filed: 1990-06-14
Abstract: PURPOSE:To lower a signal frequency and eliminate fear of mistake in response of a control system even during high speed revolution by dividing a signal of a magnetoelectric converting element to 1/(n-2) to form a number-of- revolutions detecting signal. CONSTITUTION:A stator 4 winding a coil 3 for each phase is arranged at the inside of a rotor magnet 2 of rotatable rotor 1 and the coil 3 is commutated by a magnetoelectric converting element 6 such as a hall element for each phase provided to a printed circuit board 5. An output signal of the magnetoelectric converting element 6 for commutation is used as the signal for detecting the number of revolutions. Particularly, the number of poles of motor is reduced to 1/(n-2) so that one pulse signal is outputted for a single rotation in order to eliminate influence of fluctuation of magnetization pitch of the rotor magnet 2. Thereby, a control circuit can easily be formed in the high speed region without lowering the rotating accuracy and moreover effect of low cost may be obtained since the magnet for detecting the number of revolution and coil are no longer necessary.

Title: Transmission system of optical fiber
Inventor: HIRATSUKA TOSHIO
IPC: G02B6/10
Filed: 1984-07-26
Abstract: PURPOSE:To obtain more general and more inexpensive optical fiber transmission system by roughening an edge surface which is connected to a photodetecting diode module of second optical connector. CONSTITUTION:As an edge surface 40 of a rough sourface optical connector 22 of transmission side is roughened by, say, No.1000 abrasive paper, an optical signal which travels through an optical transmission route 20 is reflected at wide range of angle. Therefore, in the reflected lights at an edge surface 40 the portion of light which may retrogress through the optical transmission route 20 is decreased, and as a result, the effect of echo due to the retrogression becomes almost negligible. Moreover, the optical signals input to a photodetecting diode module 31 through the rough surface 40 have wide range of angles being complicatedly reflected at the rough surface 40 resulting in wider range of output angles, but the increase in loss due to the wider output angle is small because the photodetecting area of the photodetecting diode module 31 is in general sufficiently larger than the diameter of optical fiber core, and also because the distance between edge surface and photodetecting surface is close enough. Thus, more general and more inexpensive transmission system of optical fiber has been realized.

Title: Damper
Inventor: IWAMOTO YASUTO
IPC: F16F15/023
Filed: 1995-06-22
Abstract: PURPOSE: To prevent the transmission of vibration and the outflow of electric viscous fluid while adjusting a damping force in a wide range in a damper using the electric viscous fluid. CONSTITUTION: Piston bodies are disposed at a predetermined interval in a cylinder 12 storing electric viscous fluid. A piston part 14 has a bulging part 14D formed at both ends into the round shape and the lower end formed into the round shape having the large radius of curvature and smoothly contiguous to the bulging part 14D. Since the resistance of the piston body in the move time is lessened, a damping force when voltage is not applied to the electric viscous fluid 24 can be restrained low and a difference between the sizes of the damping force can be enlarged, i.e., a range of adjustment of the damping force can be widened. Also, since the piston rod 14C is formed thinner than the piston body, a change in the liquid level in the moving the piston body can be reduced.

Title: Semiconductor device
Inventor: MARUSERIINUSU YOHANESU MARIA P
IPC: H01L29/78
Filed: 1988-06-27
Abstract: PURPOSE: To integrate a semiconductor device without requiring any additional space by comprising a feedback capacitor of a surface area in a semiconductor body, a dielectric layer on the surface of the semiconductor body, and a conductive layer on the dielectric layer. CONSTITUTION: In a semiconductor device in which the output terminal of an amplifier 10 is fed back to an inverted input terminal through a feedback capacitor 11, almost all of supplied electrons are stored in the capacitor 11 when the voltage amplification factor of the amplifier 10 is set at a sufficiently high value μ. Since the left quantity of the supplied electrons in a reading area 9 is little, the potential fluctuation dV in the reading area 9 is extremely small. The potential between both ends of the capacitor 11 largely changes. Because of the voltage amplification factor μ of the amplifier 10, the potential at a conductive layer 14 is increased by μ.dV as a result of the supplied electrons.  When the capacitor 11 is a MOS capacitor composed, for example, of clock electrodes 3-6, the potential increase at the layer 14 is not directly proportioned, because the capacitance of the capacitor substantially depends on the voltage across both ends of the capacitor.

Abstract: PROBLEM TO BE SOLVED: To prevent stacked transfer paper sheets from collapsing to be wedge- shaped by varying the pressurizing force which becomes paper feeding pressure when a paper feeding means feeds a transfer paper sheet which has an image already formed on the surface thereof and has entered a both-side unit.
