Abstract: PURPOSE:To provide a range hood of which shutter is not left opened by a method wherein the shutter forming a circuit in series with an operation switch of a blower is provided with a limit switch for closing a contact point when a suction port is opened and for opening a contact point when the suction port is closed. CONSTITUTION:During a terminated condition of an operation of an electric motor 4, air containing sand and dust as well as cold air in winter season is blown into a room along a duct 7 in response to a state of air pressure within or out of the room, for example, so that if the suction port 3A is closed by the shutter 9, a limit switch 10 may open an energization circuit for the electric motor 4. Under this state, even if a main body switch 11 is turned ON, the electric motor 4 may not be rotated. If the shutter 9 is opened, the limit switch 10 is closed, the electric motor 4 is rotated and the suction port 13A of a fan casing is also opened, so that the air is discharged by a vane 5.

Title: Car height adjustment control method
Inventor: YOSHIDA KENJI
IPC: B60G17/015
Filed: 1987-11-27
Abstract: PURPOSE:To enhance control accuracy by determining the value varying in the porality to be input according to a car height value bordering a dead zone corresponding to a car height objective value, counting the above mentioned value corresponding to the car height value detected every predetermined time and performing car height control comparing the discrete value with setting value based on the estimated value of car height control speed. CONSTITUTION:Based on the output signals of car height sensors 30a and 30b for detecting the car height of the front wheel side and rear wheel side, air valves 19 and 20 are controlled by means of an controller 29 for car height adjustment. This supplies and exhausts compressed air to and from air chambers 15 to 18 for adjusting the car height. In this case, a dead zone having upper and lower limits as objective car speed is set to determine the value (+1, -1) varying in the porality to be input according to car height. This value corresponding to the car height detected every predetermined time is counted one by one for computing the total number of counting. When the value reaches the first setting value, can height control starts and when the latest total number of counting reaches the second setting value (less than the first setting value), the car height control is finalized. The second setting value is calculated based on the car height control speed.

Title: Method and device for ion plating
Inventor: INOUE TAKASHI
IPC: C23C14/32
Filed: 1989-11-17
Abstract: PURPOSE:To prevent an abnormal electric discharge, etc., and to efficiently execute ion plating by ionizing the coating raw material particles formed by evaporation and accelerating the ions toward a substrate by the acceleration electric field generated when a substrate surface is electrified negative by irradiation with electrons. CONSTITUTION:The coating raw materials are evaporated by an evaporating source 6 having a power source 8 for evaporation in a vacuum vessel 1 equipped with a discharge system 10. On the other hand, gaseous Ar, etc., introduced from a gas introducing system 11 are converted to plasma by a high-frequency coil 7 disposed right above the evaporating source 6. The evaporated coating raw material particles mentioned above are ionized in this plasma. The ions are accelerated toward the substrate 5 by an electric field. The above-mentioned particles are deposited as the coating layer on the surface 5a of the substrate 5 in the insulated state on a substrate transporting tray 4. The surface 5a of the substrate 5 is irradiated with the electrons from an electron releasing source 20 and is thereby electrified negative in the above- mentioned ion plating method. The ion acceleration electric field is generated without generating the abnormal discharge based on the accumulation of positive charges in this way, by which the coating layer having good characteristics is formed with sufficient adhesive strength.

IPC: H01F1/14
Filed: 1989-11-17
Abstract: PURPOSE:To provide high saturation magnetic flux density and high magnetic permeability and to improve corrosion resistance, wear resistance, and hot workability by subjecting a magnetic alloy having a composition in which respective contents of Si, Mn, Cr, and Ti are specified to two-stage heat treatment under specific conditions. CONSTITUTION:A magnetic alloy for magnetic head core has a composition consisting of, by weight, 7.5-9.5% Si, 0.1-1% Mn, 2-8% Cr, 0.05-0.6% Ti, and the balance essentially Fe. Hot working, such as hot rolling, is applied to the above alloy to destroy a cast structure. This alloy is first heat-treated at 800-1200 deg.C, by which rolled structure is dissipated and recrystallization is carried out. Subsequently, cooling is exerted down to <=300 deg.C necessary to carry out stabilization. Then, the alloy is heat-treated again at 800-1200 deg.C so that A2 phase comprises >=60% of the internal structure. By this method, the alloy showing high magnetic permeability by alternating current even after resin molding can be obtained, and this alloy can be applied to magnetic bead for perpendicular magnetic recording.

Title: Liquid fuel burner
Inventor: ASOU TOMOMICHI
IPC: F23D11/24
Filed: 1990-11-02
Abstract: PURPOSE:To augment disturbance of an ejected liquid itself, obtain minuter fuel particles and contrive formation of a calm flame with a small flame length, by vibrating a fuel spray part in directions perpendicular to an ejecting direction by a vibrating part joined to the spray part. CONSTITUTION:Petroleum pressurized by a petroleum pump 9 to a set pressure is ejected from a jet nozzle 10, and is atomized by shearing forces due to the relative velocity thereof with respect to the ambient air. The nozzle 10 is vibrated in directions perpendicular to an ejecting direction by an ultrasonic vibrator 12 joined thereto. The vibration augments the disturbance of the ejected liquid itself, leading to further accelerated atomization, so that the petroleum is sprayed as minuter petroleum particles into a combustion chamber 15. Combustion air fed from a fan 14 is supplied through a duct 13 into the combustion chamber 15. When thus supplied, the combustion air is put into a swirl flow by swirl vanes 16, and performs a combustion reaction with the petroleum particles sprayed from the nozzle 10, thereby forming a flame.

Filed: 1991-10-18
Abstract: PURPOSE:To enable realization of high responsiveness and high stability by making a detecting element project outside a resin case body fitted on a wall surface or the like, from a measuring circuit board provided in the resin case body, and by covering the element with a metal cover. CONSTITUTION:A resin case body 2 is fitted on a wall surface 1 by foot parts 2a and a measuring circuit board 3 whereon a circuit element 3a is mounted is provided inside the case body. The board 3 is provided with a detecting element 4 such as a temperature sensor or a humidity sensor in such a manner that the base part of the element is fixed and that the element projects outside from the surface part 2b of the case body 2. Since the detecting element 4 is made to project outside the case body 2 in this way, it is affected little by a heat generated by the circuit element 3a and others. Since it is covered with a metal cover 5, besides, air A passing through upper and lower openings 5a and 5b tends to be conformable to the temperature of the cover 5 and heat radiation from the case body 2 is avoided by a metal plate 6. In a space formed by the cover and the metal plate 6, besides, temperature is made uniform by a cavity radiation effect and a stable heat balance is realized quickly.
