Title: Torque detection method for internal combustion engine
Inventor: YAMAGUCHI KIMIAKI
IPC: F02B77/08
Filed: 1979-01-16
Abstract: PURPOSE: To obtain a torque detector featuring the reduced effect of the up-down vibration caused when mounting onto the car, the temperature of the displacement detector, the aging and others by attaching the displacement detector for torque measurement at the position which is horizontally symmetrical to the shaft of the internal combustion engine.  
     CONSTITUTION: The displacement detector is attached at position A/A' and B/B' each which are horizontally symmetric to the shaft of internal combustion engine main body 1, and thus the displacement position of the rotational direction can be detected centering on the crank shaft of main body 1. The output features the opposite phase relation between detectors A and B or A' and B' respectively. Accordingly, the output obtained through addition of the output of detector A or B plus the output of detector A' or B' the phase of which is inverted by phase inverter 313 via adder 314 is applied to the torque detection circuit. As a result, the effect can be eliminated for the up-down vibration caused when mounting onto the car, the temperature of the displacement detector, the aging and other factors each.

IPC: G11B11/105
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a perpendicular magnetic recording device and method based on thermomagnetic recording that is capable of high signal resolution performance. SOLUTION: Elliptic recording light 11 is applied to a perpendicular magnetization film, and at the same time magnetic recording is made to the perpendicular magnetization film by a magnetic recording head. Since the recording light 11 has a minor axis in a track direction, a heating region 12 also becomes an ellipse with a minor axis in the track direction, thus a transition width WT of each crescent-shaped recording magnetic domain 13 is reduced as compared with a conventional one, and hence improving signal resolution performance when reproducing magnetic recording.

Abstract: PURPOSE: To suppress production of fog by providing passages (slits) between a protective material for a reflection film and a driving circuit so as to make the inside of the protective material for a reflection film communicate with the external atmosphere. CONSTITUTION: In an EC (electrochromic) mirror, an EC cell having a reflection film 4 and a supporting member 1a of a driving circuit 1b are integrated with a foamed body 2 (such as urethane) having continuous foams with an adhesive 2a, 2b applied on both faces of the foamed body 2.

Abstract: PURPOSE:To prevent the deterioration of an optical characteristic by constituting the title liquid crystal element so that a voltage pulse of a threshold level or below is not applied continuously in the same polarity direction in selection and non-selection periods. CONSTITUTION:In a driving method of a liquid crystal element formed by inserting and holding a ferroelectric liquid crystal 18 between a substrate 11 having a scanning electrode 13, and a substrate to which an electrode surface of a substrate 12 having a signal electrode 14 has been opposed, a voltage pulse of >=3 pulses containing a voltage pulse of a saturation value or above of a liquid crystal required for setting a turn-off state is applied in advance in a non-selection period. Also, at the time of setting a turn-on state, a voltage pulse of >=3 pulses containing a voltage pulse of the other saturation value or above of the liquid crystal is applied so that after this voltage pulse has been applied, a voltage pulse exceeding a threshold level of the liquid crystal is not applied, and also, an average value of a DC component in selection and non-selection periods becomes zero. In such a way, a contrast drop and a flicker, etc., of the liquid crystal element can be decreased, and also, since the DC portion is not applied to the liquid crystal element, a stable liquid crystal element can be realized.

Abstract: PURPOSE:To improve the measuring accuracy of a ring laser oscillator by forming predetermined slit in the optical path of a ring oscillator to thereby reduce the diameter of the light beam, thereby reducing the rear scattering of a laser tube from its fine tube end and reducing the width of its lock-in region. CONSTITUTION:Laser oscillation is conducted with a ring oscillator having reflecting mirrors 2, 3, 4 and laser tubes 1, 1' disposed in the ring oscillator. Thus, laser lights 5, 6 are irradiated from the ring oscillator.

Thus, the diameter of the light beam in the oscillator is sufficiently reduced lower than the diameter of the fine tubes of the laser tubes 1, 1'. Even if laser oscillated scattered light is existed in the inner surface of the slit, the light scattered backwardly is extremely reduced as compared with the case that the light is irradiated to the fine tubes 1, 1' thereby largely reducing the rear scattered light.

Abstract: PURPOSE:To execute an economical radiation design in a device which contains a multi-amplifier using a power IC for constituting two power amplifiers, by providing a limiter corresponding to a sound pressure difference of a tweeter and a woofer, on an input of the power amplifier for the tweeter. CONSTITUTION:An input signal which has passed through a buffer amplifier 1 is applied to a high-pass filter 2 and a low-pass filter 5. The input signal which has passed through the high-pass filter 2 is outputted to a tweeter 4 through a power amplifier 3a. The input signal which has passed through the low-pass filter 5 is outputted to a woofer 6 through a power amplifier 3b. The input signal which has passed through the high-ass filter 2 is limited by a limiter constituted of Zener diodes 7, 8, therefore, an output of the power amplifier 3a is limited. In this way, by lowering the output of one power amplifier, an economical radiation design can be executed in a device which contains a multi- amplifier using a power IC which can constitute two power amplifiers.
