摘要:
A high frequency switching circuit in which, to reduce power dissipation of a switching element, the characteristic impedance defined by the inductance of a transformer connected in series with the switching element and the capacitance of a capacitor connected in parallel with the switching element, the ratio of the input voltage and an output voltage, and the ratio of ON time and a switching period T of the switching element are each selected within a given range. Alternatively, a ratio pertaining to a leakage inductance of the transformer and an inductance of an additional inductor, and a ratio pertaining to the output and input voltages are selected to satisfy a predetermined relation and the characteristic impedance is selected within a given range.

A plasma actuator (1) includes four electrodes (11) and three dielectrics (10) and is disposed on the side of an object surface (B). When a high voltage is applied to the electrodes (11), a plasma (15) is generated at an end (10a) of each dielectric (10) exposed so as to be accessible to a gas. In the plasma actuator (1), the electrodes (11) and dielectrics (10) are alternately stacked one on another. The plasma actuator (1) includes a stepped exposed portion (X). The plasma actuator (1) in which the electrodes (11) and dielectrics (10) are arranged such that the ends (10a) of the dielectrics (10) are exposed in the normal line direction of the object surface (B) in the stacked order in the stepped exposed portion (X) can suppress the flow of the generated plasma even when the plasma actuator is exposed to a high-speed airflow under high pressure. This stabilizes the plasma.

Provided are an airbag and an airbag device whose size of a package when the airbag is folded can be reduced while demonstrating effects of an inner chamber. An airbag device in the present invention includes a gas generator configured to generate gas under predetermined conditions, an airbag connected to the gas generator to be inflated and deployed, and a retainer configured to accommodate the airbag. The airbag includes an inner panel arranged in the interior thereof and a connection panel having a surface area smaller than the inner panel, and the inner panel includes a center seamed portion connected to an inner surface of the airbag with respect to the direction of thickness and a plurality of outer peripheral seamed portions connected to the connection panel which is arranged on the inner surface of the airbag apart from the portion where the center seamed portion is connected. The outline of the inner panel 4 between the outer peripheral seamed portions when the inner panel is deployed in a plane is formed into a shape following a straight line connecting the outer peripheral seamed portions.

To provide an art capable of easily generating accurate teaching data from a small number of teacher images.The image of a standard object is captured to extract a characteristic value from the teacher image of the standard object through image processing while making a user input the already-known knowledge for a configuration of an object and an object such as a tolerance and entering the knowledge in a knowledge base. Then, context data in which various attributes which can be objects are described together with their semantics is generated in accordance with the characteristic value extracted from the teacher image of the standard object and the knowledge entered in the knowledge base. Moreover, attributes corresponding to types of characteristic values used for recognition processing are extracted from the context data entered in the knowledge base to generate the teaching data for the recognition processing.

An ultrasonic sensor has a sensor body and a bezel having a metal spring attached on a side wall thereof for installation on a vehicle component. A free end of the metal spring is positioned to protrude from a through hole of the side wall, is pressed by a portion of the sensor body that is inserted in a hollow space of the bezel, and is pushed back by an opening face of the sensor body. In this manner, the bezel is firmly attached on the component and the sensor body is firmly attached on the bezel.

A PC board inspecting method capable of detecting deviation of an IC component at high speed with small storage capacity utilizes inspection logic particular to a component to be inspected. The inspection logic includes a color condition for specifying a color appearing in the body of the component to be inspected. The component is radiated with a plurality of color rays at different angles of incidence. An image formed by reflection light of the color rays is captured, and an inspection image including at least part of an edge of the body of the component to be inspected is captured. By using the color condition, a component body area satisfying the color condition is extracted from the inspection image by an image process.
