IPC: B22D27/02
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To restrain the defect such as crack, segregation, and to obtain a steel material having little defect and excellent quality such as corrosion resistance, by pouring molten steel containing Mg oxide into a mold and continuously casting while stirring the molten steel with an electromagnetic stirring device to make a steel slab having fine and uniform solidified structure.

Title: Semiconductor acceleration sensor
Inventor: UCHIKOSHI SUSUMU
IPC: G01P21/00
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor acceleration sensor of which electrostatic self-diagnosis sensitivity and damping characteristics can be set precisely. SOLUTION: The semiconductor acceleration sensor is provided with a semiconductor substrate 1 on which a movable part is formed of a weight part 3 and a beam part 2, a conductor electrode 9 disposed oppositely to the bottom face of the weight part 3 through a microgap 7, and a base 4 for supporting the conductor electrode 9. The size of the conductor electrode 9 on the side facing the bottom face of the weight part 3 is set smaller than the size of the bottom face of the weight part 3. Although the facing area depends on the size at the facing part of the conductor electrode 9 having smaller dimensions than the bottom face of the weight part 3, the size at the facing part can be set by the groove part 8 in the base 4 which can be set precisely.  Consequently, the facing area can be set precisely regardless of fluctuation in the size of the bottom face of the weight part 3 and thereby, the electrostatic self-diagnosis sensitivity and the damping characteristics can be set precisely.

Title: Multipolar spark plug
Inventor: AMANO KOZO
IPC: H01T13/46
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To improve the ignition property by forming a central electrode tip with a large diameter, setting the outer diameter of the large diameter part larger than the outer diameter of the central electrode by a prescribed value, and setting (thickness of large diameter part)/(axial distance of discharge surface) to a prescribed value. SOLUTION: A dipolar spark plug A has a central electrode tip 32 formed with a large diameter, the outer diameter d2 (ϕ2.5) of this large diameter part 31 is set larger than the outer diameter d1 (ϕ2.0) of a central electrode 3 by 0.5mm, and [thickness T1 (0.4mm) of the large diameter part 31]/[axial distance L (1.5mm) of discharge surface] is set to about 0.27. Since a spark discharge is thus caused between a discharge surface front side 411 and the part 31, A/F lean limit is improved by about 1, and satisfactory ignition property can be held. Further, since the diameter difference is 0.5mm, the temperature of the large diameter part (central electrode 3 tip) is never remarkably increased, and the wear of the electrode tip part by spark discharge is minimized.  Thus, in the plug A, the reduction in spark wear resistance of the electrode 3 is almost eliminated by providing the part 31.

Title: Filter tank provided with packed layer of floating granular material to upper part of filter layer
Inventor: MARUE YOZO
IPC: B01D29/62
Filed: 1987-06-15
Abstract: PURPOSE:To enhance filtration capacity and to reduce back washing time by charging a floating granular material having a diameter larger than the particle diameter of a granular filter medium at thickness of two-times or more of the particles diameter thereof into the upper part of the filter layer of the granular filter medium. CONSTITUTION:A floating granular material 7 (especially 20-100mm particles diameter, 0.05-1.5 apparent specific gravity, a spherical shape, a rectangular parallelopiped and a columnar shape, etc., are preferable) which has a diameter larger than the particle diameter of a granular filter medium and can be freely moved is charged at mean packing thickness of two-times or more of the particle diameter of the granular material 7 into the upper part 6 of a filter layer 2 consisting of the granular filter medium such as sand. When the flow of raw liquid is passed through the layer of the floating granular material 7, it is broadly dispersed and rectified and therefore the filter layer can be uniformly utilized and filtration capacity is enhanced. On the other hand, at a time of back washing, the granular material 7 is mixed together with the filter medium and floated and dirt stripping of the filter medium is promoted by its contact, collision and rolling and thereby back washing time can be shortened. When the back washing is finished, the granular material 7 is built up to a layer to the upper part of the filter layer 2 in its former condition by means of the difference of settling velocity for the filter medium.

Abstract: PROBLEM TO BE SOLVED: To miniaturize a vacuum cleaner by a method wherein a current detecting means which detects the consumption current of an electric blower, an amplifying means which amplifies the output, and a control means which controls the electric blower in response to the output of the amplifying means are provided, and a plurality of amplifying means are provided, and the degree of the amplification is made variable in response to an air volume. SOLUTION: Power is fed to an electric blower 2 from a commercial power source 3, and the consumption current of the electric blower 2 is detected by a current detecting means 4. Then, when an air volume is large, the output of the current detecting means 4 is amplified by a second amplifying means 5a, and when the air volume is intermediate or small, the output of the current detecting means 4 is amplified by a third amplifying means 5b, and the amplified value is input in a control means 6, and the electric energy which is fed to the electric blower 2 is controlled.  Thus, in a region wherein the reduction amount of the consumption current is small, and the air volume is large, the second amplifying means 5a of which the degree of the amplification is large is used, and in a region wherein the reduction amount is large, and the air volume is intermediate or small, the third amplifying means 5b of which the degree of the amplification is small is used, and thus, even a delicate change of the consumption current can be detected, and the detection precision of the consumption current can be improved.

Title: Flow direction detector for fluid
Inventor: YAMAMOTO ASAYUKI
IPC: G01P5/12
Filed: 1986-06-23
Abstract: PURPOSE:To detect the flow direction, etc., of fluid in a fine space and a flow passage stably for a long period by constituting a detector so that the flow of the fluid can be detected electrically. CONSTITUTION:When a source voltage is applied between an input terminal IN and GND, a heater H generates heat. When a positive characteristic thermistor is used as the heater, a temperature self-control function operates and stable heating value is obtained in correspondence to the source voltage. A resistance RL is a current limiting resistance and limits currents flowing through thermistors Th1 and Th2. If the fluid does not flow, the potential at an output terminal OUT 2 is a half as high as the voltage between an output terminal OUT 1 and GND on condition that the resistance values of the thermistors Th1 and Th2 are equal to each other. Further, when the fluid flows, the thermistor Th1 and Th2 vary in resistance value and, for example, when the fluid flows in the direction from the thermistor Th1 to the thermistor Th2, the temperature of the thermistor Th1 drops and the resistance value increases. Simultaneously, the temperature of the thermistor Th1 rises and the resistance value decreases. Consequently, the potential at the output terminal OUT 2 drops and the flowing direction of the fluid can be detected.
