Inventor: NAKADA MORITSUNE
IPC: B60G17/015
Filed: 1989-03-24
Abstract: PURPOSE:To constantly perform a proper control by compensating for output corresponding to at least one of a spring force originated from a relative displacement between a car body and each wheel, and a damping force originated from a differential value of the relative displacement in accordance with an composition force based on the prediction results of the change in attitude of the car body. CONSTITUTION:A means A detects a relative displacement between a car body and each wheel at the front and rear, and right and left, and a means B generates a first output corresponding to at least one of a spring force originated from the detected value and a damping force originated from the deferential value of the detected value. A means C then predicts the change in attitude of the car body, and a means D generates a second output corresponding 10 an opposition force based on the prediction results. Further, a means E compensates for the first output in accordance with the second output. A signal corresponding to a command value determined by the sum of the second output and a compensated first output is outputted from a means F to a control valve G. In this way, the working fluid pressure of a fluid pressure cylinder H located between the car body and each wheel is controlled.

Title: Coercive force measuring method for magnetic material
Inventor: OOKUBO HIROYUKI
IPC: G01R33/14
Filed: 1981-05-16
Abstract: PURPOSE:To speed up the inspection of the quality and characteristics of a magnetic material by relatively moving a magnetic material, reduced in magnetism by a constant magnetic field after being magentized in one direction until it is saturated, and a magnetic flux detection part at a certain speed, and then observing a spatial distribution of coercive force. CONSTITUTION:A magnetic material while conveyed by a conveying device is applied with a magnetic field H1 generated by an energizing coil 3 to be magnetized in one direction until DC saturation is obtained. Then, the magnetic material is sent in the opposite direction and reduced in magnetism by being applied with a constant magnetic field H2 in the opposite direction to the magnetic field H1 by the coil 3. Consequently, the magnetic material 1 has induced magnetic flux with density which corresponds to variance in spatially distributed coercive force. Then, this magnetic material 1 is run at a constant speed by the conveying device, and consequently a detection voltage which corresponds to  the spatial distribution state of the coercive force of the material 1 is induced  across a search coil 2.

IPC: G03G9/08
Filed: 1983-04-28
Abstract: PURPOSE:To provide excellent cleanability and to prevent photographic fog and edge effect by using a compsn. consisting of a resin binder, a specific amt. of a coloring agent with respect to the amt. of said binder, and a fine particle conducting agent of tin oxide-antimony oxide. CONSTITUTION:A compsn. consisting of a resin binder for fixing 1-30pts.wt., by the weight of the binder, a coloring agent and 0.5-20wt.% fine particle conductive agent of tin oxide-antimony oxide is incorporated in a toner. The fine tin oxide-antimony oxide particles used as such conducting agent has excellent uniform dispersibility in the resin for fixing and has no tendency at all to bleed- out. The particles are chemically and thermally stable and the color toner compounded with such conducting agent has stable electrical resistance even if the toner is subjected to heat, light and electric discharge. The toner remains consistent in spite of a charge of humidity. The volumetric resistivity of the conducting agent is as low as about 1-5OMEGAcm, and the color tone thereof is transparent, white or pale color. The electric resistance of the toner is adjustable to an adequate range with a small addition of such agent and no adverse influence is given on the hue of the toner. Cleanability is thus improved and the photographic fog and edge effect is prevented.

Title: Electronic watch
Inventor: JIYANNKUROODO FUATON
IPC: G09F9/30
Filed: 1980-06-02
Abstract: In an electronic watch the indication of the time (hours, minutes and possibly seconds) is given in analog form by means of a first passive electro-optic display cell. The display segments of this first display cell are arranged radially with respect to a central point, and the activated segments thereof have the appearance of the conventional hands of an analog watch. The watch comprises a second passive electro-optic display cell furnishing information in digital form, for example indicating the day of the week and the date. So that only the second cell need be provided with an illuminating device, the watch comprises a selector which is manually operable by means of a push-button which, when it is operated, causes the time to be displayed by the second cell at the same time as the illuminating device thereof is operated. This arrangement enables the user to know the time in the dark without it being necessary to provide the first cell with an illuminating device.

Title: Air spring
Inventor: TERADA KATSUYUKI
IPC: F16F9/04
Filed: 1980-06-04
Abstract: PURPOSE:To decrease the vibration of a swing bolster and a car body by a method wherein a throttling is changed by the pressure difference of the air spring and the inside of an air chamber of the swing bolster in proportion to the speed of vibration, and the more the vibration is sudden, the more the rate of vibration damping increases. CONSTITUTION:When the swing bolster 7 and an upper surface plate 3 of the air spring move in the arrow head 31 direction, the pressure of an air chamber 2 in the air spring increases in proportion to the speed of movement, the pressure of the air chamber 2' of the swing bolster 7 decreases, and differential pressure is generated, and a communicating cylinder 18 which is subject to the differential pressure by a communicating cylinder flange 21 is connected to an outer cylinder 12 by a diaphragm 22. Accordingly, the communicating cylinder 18 moves upward in proportion to the differential pressure, and stops at a balanced position with an elastic body 23. In this case, the larger the communicating cylinder 18 moves upward, the smaller the area of an air passage of the throttling 30 is because a central section of an inner surface 29 of the communicating cylinder is convex. Accordingly, the rate of vibration damping due to the throttling 30 increases.

Title: Method for measuring thickness of gamma-fe2o3 film
Inventor: SUZUKI SONOKO
IPC: G01N21/35
Filed: 1989-03-27
Abstract: PURPOSE:To make it possible to measure the thickness of gamma-Fe2O3 film simply without destruction by measuring infrared-ray reflection spectrum based on the stretching vibration of Fe-O in the gamma-Fe2O3 film which is formed on a substrate that reflects infrared rays. CONSTITUTION:On a substrate, e.g. an Al alloy substrate and the like, which reflects infrared rays, a gamma-Fe2O3 film is formed. Said sample is measured by a reflecting method using infrared-ray spectrophotometer. The thickness of the film is obtained in comparison with a peak area based on the Fe-O bonding in the gamma-Fe2O3 film beforehand. Namely, a calibration curve is formed based on the value which is measured by a probe method accurately once and the value obtained by an infrared-ray spectroscopic method. Thereafter, the film thickness of the sample whose film thickness is unknown is measured only by the infrared-ray spectroscopic method by using the film thickness value i.e. said calibration curve. In the characteristic chart indicating the infrared-ray reflection spectrum of the gamma-Fe2O3 in the figure, the peak area between A and B is obtained when the straight line connecting two points A and B is obtained.
