  • Patent number: 10693224
    Abstract: A radio-wave transmitting cover is configured to be arranged in the path of the radio wave of a radio-wave radar device. The thickness of the cover is set to a reference thickness at a reference position where the incident angle of the radio wave from the radio-wave radar device is 0°. The reference thickness is set to a value obtained by multiplying half of the wavelength of the radio wave by an integer. In the area around the reference position, the thickness of the cover is gradually changed such that the greater the distance from the reference position, the greater becomes the difference by which the thickness of the cover is larger than the reference thickness.

  • Patent number: 9766111
    Abstract: A liquid surface detector includes a terminal, a covering portion, and a sealing film. The terminal includes a ridge portion between a first wall face and a second wall face. The terminal sends an electric signal relating to detection of height of a liquid surface. The covering portion covers the terminal. The sealing film is formed between the terminal and the covering portion and is put into close contact with the terminal and the covering portion. The terminal further includes a groove and two second slant faces. The groove has a V-shape in cross-section and includes two first slant faces. The groove cuts off in the V-shape the ridge portion of an area of the first wall face covered with the sealing film. The two second slant faces respectively connect together an area of the second wall face covered with the sealing film and the two first slant faces. A boundary portion formed by contact between the two second slant faces which are opposed to each other is continuous with a top portion of the groove.

  • Patent number: 9677925
    Abstract: A housing of a liquid level detection device includes an inner case, which has a first wall portion, and a terminal, which has a projection that extends through the first wall portion and projects to an outside of the inner case. The first wall portion and the projection are covered with a covering portion. A first seal film, which connects between an outer peripheral surface of the projection and the first wall portion, is formed in an inside of the covering portion. A film thickness of the first seal film along an edge line of the terminal progressively increases toward the first wall portion.

  • Publication number: 20120264528
    Abstract: A screw manufacturing method by thread whirling machining and others are provided which can solve problems due to thread rolling and cutting and which inhibits moving paths of inserts from interfering with a curved line of a desired screw upon going in and out, thereby providing the screw with a targeted curved line. In the method of manufacturing a screw, a mount angle of the screw is calculated by formulae below in case that a lead angle of the screw is different from the mount angle. mount angle=tan?1{n×pitch/(?×D1)}??(1) D1={(screw valley diameter+screw outer diameter)/2}+?T??(2) screw valley diameter?D1?screw outer diameter??(3) in case ?T>0, {(screw outer diameter?screw valley diameter)/2}×0.2<?T<{(screw outer diameter?screw valley diameter)/2}??(4) in case ?T<0, ?{(screw outer diameter?screw valley diameter)/2}<?T<?{(screw outer diameter?screw valley diameter)/2}×0.2??(5) where D1?0, ?T?0, and n indicates a number of threads.

  • Patent number: 5094840
    Abstract: A novel foaming agent in dentifrice compositions, e.g., tooth pastes, is proposed which is an at least partially, with a basic compound, neutralized salt of a glycerin diester compound represented by the general formulaR.sup.1 --CO--O--CH.sub.2 --CHOH--CH.sub.2 --O--CO--R.sup.2,in which R.sup. 1 --CO--is a residue of a monobasic carboxylic acid having 8 to 18 carbon atoms in a molecule, e.g., lauric acid, and R.sup.2 is a residue of a polybasic carboxylic acid, e.g., succinic acid, from which one of the carboxyl groups is eliminated of which is a 1% by weight aqueous solution has a pH value in the range from 4 to 10 at 25.degree. C. The dentifrice composition compounded with 0.1-10% by weight of the above defined foaming agent has outstandingly high foamability and is advantageous in respect of the little adverse influences on the stability of enzymes contained in the dentrifrices composition.

  • Patent number: 4942099
    Abstract: Unit cells and separator elements are stacked in layers, thus constituting a stacked structure of a fuel cell. A first segment channel, which is bored through the peripheral region of each separator element, communicates with a second segment channel formed in a cylindrical seal member which is joined to each two adjacent separator elements. Thus, manifolds for the intake and exhaust of a fuel gas and an oxidant gas are defined. The cylindrical seal member includes a pair of ring-shaped metal members joined to each two adjacent separator elements and a ring-shaped insulating member interposed between the metal members. Thus, the gases in the manifolds can be prevented from leaking out, and the adjacent separator elements are insulated from one another.
