摘要:
This invention relates to a non-slip structure, which is highly efficient in preventing a slip with no trouble caused by a through hole, thereby enhancing reliability.The non-slip structure of this invention is characterized in that a portion of a metal plate such as a steel plate and the like is sheared so as to form cutting lines (a pair of lateral side cutting lines and a joining cutting line) for forming a protruded piece and, at the same time, the protruded piece is pulled up along the cutting lines to a height, which does not exceed the thickness portion of the steel plate so as to raise the shearing surface (edge), so that the sheared surface does not form a gap nor any through hole in contacting the steel plate.

The invention provides a slip stopper which achieves a great slip stopping effect, and can be used for a location where a problem occurs if a through hole is opened therein. In a protruding portion that protrudes from the upper surface of a steel plate in the plate thickness direction, a concave portion and drain channels, that lead to the steel plate upper surface from the concave portion, are formed. The inner surface of the concave portion and the groove side surfaces of drain channels are formed by shear planes which extend substantially perpendicular to the steel plate upper surface, and are obtained by half blanking that does not open a through hole in the steel plate.

An easy manufacturing method of a slip stopper, and apparatus therefor, that has a great slip stopping effect and can be used for a location where a problem occurs if a though hole is opened therein. After a protruding portion is formed on a steel plate, by using a first punching die unit, so as to protrude from the upper surface in a plate thickness direction, a concave portion and drain channels are formed in the protruding portion by shear planes that extend substantially perpendicular to the steel plate upper surface and have been half-blanked so as not to open a through hole in the steel plate by using a second punching die unit.

An object of the present invention is to provide an artificial tissue construct that has means for transporting nutrients, oxygen, waste products, or the like and is viable in vivo. The present invention relates to a tissue construct formed in vitro, which comprises a vascular layer, a basal membrane layer, and a tissue-forming cell layer.
摘要:
A method for producing a cell culture substrate to which cells adhere in a finely processed pattern while retaining the pattern for a long period of time to culture the cells and a production apparatus used in the production method. The method includes: forming a patterning substrate by forming: on a base material, a light shielding portion, and a cell adhesive layer having adhesion to a cell and containing a cell adhesive material which is decomposed or denatured by an action of a photocatalyst upon energy irradiation so as to cover the light shielding portion; an energy irradiating process of irradiating energy to the patterning substrate from the base material side to form a pattern; and a cell adhesion process of making the cell adhere to the cell adhesion portion in a cell culture medium containing the cell and a culture medium.

Valid code data and invalid code data are alternately input to a register that fetches data synchronously with a clock signal. A state of a data value input to the register is monitored. Each time when it is determined that the data is stabilized by the valid code data, the register holds the valid code data.

A main object of the present invention is to provide an artificial tissue capable of transporting the nutrition necessary for maintaining the activity of the cells or tissues. To achieve the object, the present invention provides an artificial tissue including a blood vessel-containing tissue layer having at least two adjacent blood vessels and a cell disposed between the blood vessels, characterized in that an interval between the two adjacent blood vessels in the blood vessel-containing tissue layer is formed by a nutrition supplyable distance which does not cause a necrosis of the cell.
摘要:
The present invention intends primarily to provide such as a cell culture patterning substrate that is used to adhere a cell in a highly precise pattern on a base material to culture and a cell culture substrate on which a cell is adhered in a high precision pattern. In order to achieve the above-mentioned object, the present invention provides a patterning substrate having a base material and a cell culture patterning layer that is formed on the base material and has at least a photocatalyst and a cell adhesive material that has the adhesiveness with the cell and is decomposed or modified owing to an action of the photocatalyst in combination with energy irradiation.

The disclosure is directed to an improved coaxial resonator such as a .lambda./4 coaxial resonator or the like to be used for an electrical filter or oscillator, etc. which operates, for example, in UHF ranges. The coaxial resonator includes a stator electrode provided on the resonator main body, a rotor of a dielectric material formed with a rotor electrode confronting the stator electrode and rotatably mounted on the resonator main body so as to vary capacity between the stator electrode and the rotor electrode through rotation of the rotor for alterations of the resonance frequency.
