  • Patent number: 10876991
    Abstract: Disclosed is a stacked-type plate-shaped sensor element for detecting the concentration of a specific gas component in a gas under measurement. The sensor element includes: a first ceramic layer; a pair of measurement and reference electrodes stacked on a front end part of the first ceramic layer; a through hole formed through at least the first ceramic layer in a rear end side of the sensor element; a through hole conductor disposed on an inner wall of the through hole; a porous reference lead extending between the reference electrode and the through hole conductor; a gas-impermeable second ceramic layer arranged on the first ceramic layer to cover at least the reference lead; and a ventilation portion provided, in the form of a hollow space or a porous substance, between the first and second ceramic layers at a position facing the through hole and communicating with the reference lead.

  • Patent number: 9696274
    Abstract: A gas sensor element of an air/fuel ratio sensor has a structure in which at least a part of an end portion of a porous electrode is sandwiched between a porous member and a solid electrolyte member. Therefore, it is possible to restrain shrinkage of the porous electrode during manufacture of the gas sensor element, which shrinkage would otherwise occur at the time of heating in a debindering step or at the beginning of a firing step, whereby occurrence of green breakage in the solid electrolyte member is restrained. Thus, cracking due to green breakage is restrained from occurring in the solid electrolyte member produced through firing. Since the end portion of the porous electrode can receive oxygen through the porous member, blackening of the solid electrolyte member can be prevented.

  • Patent number: 8801070
    Abstract: Disclosed is a resin garnish attached to a door frame forming the window frame of a vehicle door. The door frame is provided with a frame unit including an attachment unit having an insertion hole, and a weatherstrip fastened to said frame unit using a clip. The clip is inserted through the weatherstrip and the insertion hole to fasten the weatherstrip to the frame unit by engaging with the frame unit. The garnish is provided with a garnish body forming a design surface facing out of the vehicle, and an engaging protrusion unit arranged so as to protrude from the garnish body. In order to attach the garnish to the frame unit, the engaging protrusion unit is configured such that said unit, in a state inserted in the insertion hole, engages with an engaging claw provided on the clip.

  • Patent number: 6589511
    Abstract: The composition for forming solid particles of the present invention comprises a biodegradable polymer, a solvent, a polyhydric alcohol, a viscosity-increasing agent, and an active drug, wherein the composition is in the form of an emulsion comprising a continuous phase rich in the polyhydric alcohol and the viscosity-increasing agent and a dispersed phase of liquid particles rich in the biodegradable polymer and the solvent, the dispersed phase being present in said continuous phase. The above composition can allow the carrier comprising an active drug to reach all corners of narrow periodontal pockets, and the carrier comprising the active drug has high retention in the periodontal pockets, whereby making it possible to maintain the active drug for a long period of time at a high concentration.

  • Patent number: 5337341
    Abstract: An X-ray radiographic apparatus has an electronic shutter circuit operable at a photographing time to vary time for storing electric charges in a CCD image pickup device. This avoids saturation of the CCD image pickup device due to an increased quantity of X-rays. Further, an image outputted from the CCD image pickup device is latched at the photographing time for improved durability and responsibility. A photographed image may be observed on a monitor unit also after photo taking.
