An inspection device for a pillar shaped honeycomb filter includes: a housing portion that can house a pillar shaped honeycomb filter; an introduction pipe and a discharge pipe through which a gas can flow, each of the introduction pipe and the discharge pipe being connected to the housing portion; a particle generation portion for generating particles; a particle introduction portion for introducing the particles generated by the particle generation portion into the introduction pipe; a gas stirring portion arranged in the introduction pipe on an upstream side of the particle introduction portion in a gas flow direction; and particle counters for measuring the number of particles, the particle counters being arranged in the introduction pipe and the discharge pipe on a downstream side of the particle introduction portion in the gas flow direction.

Inspection device and inspection method for pillar-shaped honeycomb filter

An inspection method for a pillar-shaped honeycomb filter having a honeycomb-shaped first end face and a honeycomb-shaped second end face, including:

Inspection method for pillar-shaped honeycomb filter

A bottom face processing method of a pillar-shaped honeycomb structure including steps of:

Bottom face processing method of pillar-shaped honeycomb structure, manufacturing method of fired honeycomb structure, and manufacturing method of joined body

A method for producing a honeycomb structure, the method including: a step of drying a pillar-shaped honeycomb formed body including partition walls that define a plurality of cells each forming a flow path penetrating from a first end face to a second end face; and after the step of drying, a step of cooling the honeycomb formed body by applying a suction force to the first end face of the honeycomb formed body to allow a coolant to flow in the honeycomb formed body from the second end face, pass through the cells, and flow out from the first end face.

Method for producing honeycomb structure

A masking method for honeycomb formed body, including bonding a film on at least one bottom face of a honeycomb formed body in a quadrangular prism shape such that an adhesive surface is in contact with the bottom face. The step of bonding the film includes bonding of the film so as to have a bottom face covering portion that covers a whole surface of the bottom face and a pair of outer edge portions along one pair of opposite sides of a quadrangle defining an outer peripheral shape of the bottom face and a pair of protruding portions protruding from another pair of opposite sides of the quadrangle. At least a part of the adhesive surface of each of the pair of protruding portions is bonded so as to be in contact with a pair of opposing lateral faces of the honeycomb formed body.

Masking method for honeycomb formed body, plugged portion forming method for honeycomb formed body, and manufacturing method of honeycomb fired product

The manufacturing method of the plugged honeycomb structure includes a honeycomb structure forming step of forming a pillar-shaped honeycomb structure, and a plugging step of forming plugging portions in end portions of the cells of the honeycomb structure formed in the honeycomb structure forming step, and in the plugging step, there is performed a press pouring operation of pressing one end face of the honeycomb structure into a plugging slurry stored in a bottomed tubular container to pour, under pressure, the plugging slurry into the cells of the honeycomb structure, and as the plugging slurry of the plugging step, there is used a slurry in which a yield point viscosity of a viscous fluidity is 600 Pa&#xb7;s or more, a recovery viscosity is 300 Pa&#xb7;s or more, and a high shearing viscosity is 200 Pa&#xb7;s or less.

In an electronic device, a slider is disposed in an insertion opening of a housing of a card edge connector. The slider is movable with an insertion operation of a circuit board into the insertion opening from an initial position before the circuit board is inserted to an insertion completed position where the insertion operation of the circuit board is completed by being pushed by the circuit board. When the slider is at the initial position, terminal projections are supported on a support surface of the slider in a resiliently deformed condition so that contacts are separated from an electrode-formed surface of the circuit board. When the slider is at the insertion completed position, the terminal projections are completely separated from the slider and in a state of applying a spring back force of resilient deformation to the circuit board through the contacts.

Electronic device having card edge connector

A DC source generates a DC voltage between a positive electrode and a negative electrode. An inductive element and a parallel-connected switch-circuits unit are provided in a conductive path extending from the positive electrode to the negative electrode. The parallel-connected switch-circuits unit includes a plurality of switch circuits connected in parallel with one another. The switch circuit opens and closes the conductive path in accordance with a drive signal inputted from a drive circuit. The drive signal causes the plurality of switch circuits to successively perform an ON operation in which the conductive path is closed and then opened. A pulse voltage generation period in which a pulse voltage occurs in the inductive element continuously follows an ON period which is a duration from when the conductive path is closed to when the conductive path is opened.
