摘要:
A passivated film on a surface of a high-alloy steel member makes it difficult to apply diffusion treatment, such as gas nitriding or gas carburizing, that forms a nitrided layer, carburized layer or carbonitrided layer on the surface of the steel member. An activating treatment method is provided for the surface of the metal member. This method is not accompanied by problems of conventional activation treatment with a halide, such as furnace deposits, furnace wall erosion and effluent gas detoxification treatment, and is useful as pretreatment for diffusion treatment. According to this method, the passivated surface of the high-alloy steel member can be activated by using a gas commonly employed in gas heat treatment, and forming HCN gas in a heating furnace while making use of catalytic action of the steel member or a surface of the furnace.

A particular program detection device is provided which can detect a particular program segment even in a program signal contaminated with noise by adaptively modifying a detection sensitivity for a scene change point. A noise level detecting section (12) detects a noise level of a program signal outputted from a signal input section (11). Based on the noise level detected by the noise level detecting section (12), a detection sensitivity determining section (13) determines a detection sensitivity which is used when a silent portion of the program signal is determined by a silent portion detecting section (14). In accordance with the detection sensitivity determined by the detection sensitivity determining section (13), the silent portion detecting section (14) detects a portion having a low audio level of the program signal as a silent portion. A particular program determining section (15) calculates a time difference between each silent portion detected by the silent portion detecting section (14) and a silent portion following this, and based on the calculated time difference, determines whether or not the silent portion is a particular program.

There is provided a harmonic structure acoustic signal detection device not depending on the level fluctuation of the input signal, having an excellent real time property and noise resistance. The device includes: an FFT unit (200) which performs FFT on an input signal and calculates a power spectrum component for each frame; a harmonic structure extraction unit (201) which leaves only a harmonic structure from the power spectrum component; a voiced feature evaluation unit (210) which evaluates correlation between the frames of harmonic structures extracted by the harmonic structure extraction unit (201), thereby evaluates whether or not the segment is a vowel segment, and extracts the voiced segment; and a speech segment determination unit (205) which determines a speech segment according to the continuity and durability of the output of the voiced feature evaluation unit (210).

A stator blade 13 has a blade tip 14, a blade trailing edge 15, a back 16 and a face 17. The blade tip 14 is an edge of the peripheral surface of the stator blade 13 near the turbine. The blade trailing edge 15 is an edge of the peripheral surface of the stator blade 13 near the impeller. The back 16 is a portion of the peripheral surface of the stator blade 13 extending between the blade tip 14 and the blade trailing edge 15 and opposed to the impeller 4, and has a streamline section. The face 17 is a portion of the peripheral surface of the stator blade 13 extending between the blade tip 14 and the blade trailing edge 15 and opposed to the turbine 5, and is formed of a streamline portion 17a and a plane portion 17b located near the blade tip 14. The shape of the stator blade 13 is such that a capacity coefficient (Cf) of a torque converter is lower when a speed ratio (e) is 0, and thereby improving fuel consumption during idling.

摘要:
In an electronic component series of the type wherein a plurality of electronic components are distributed in the longitudinal direction of a tape-like receiving member to be retained by the same, a cover tape is heat-sealed to a receiving tape having receiving concavities for receiving the respective electronic components. Stepped portions or protrusions are forned in the receiving tape to define regions not in contact with the cover tape. This restricts the extent of the sealed regions wherein the cover tape is heat-sealed to the receiving tape, such that the sealed regions are substantially constant in width which results in a substantially constant force being required for removing the cover tape from the receiving tape.

A slide switch includes a case forming an accommodation space, a first contact disposed in the accommodation space, a second contact disposed in the accommodation space, a third contact disposed in the accommodation space, and a slider fixed to the third contact. The slider is movable between a first position in which the first contact and the second contact are electrically insulated from each other and a second position in which the first contact and the second contact are electrically connected to each other via the third contact. The case includes a projection supporting the third contact in a normal direction of a plane which includes a moving path of the slider in the accommodation space.
