摘要:
A vibration membrane is formed by a laminate consisting of a piezoelectric film on both surfaces of which electrode coats are formed respectively and a soft sheet on both surfaces of which metal coats are formed respectively, and a weight is mounted on one of the surfaces of the vibration membrane. A pair of frame-like elements is provided to support the peripheral portion of the vibration membrane on each side by one frame-like element. The peripheral portion of the vibration membrane is supported by the pair of frame-like elements by accommodating the vibration membrane and the frame-like elements in a casing one end of which is open and closing the open end of the casing by a board.

摘要:
A condenser microphone in which a back electrode, disposed oppositely to the rear surface of a diaphragm, and a circuit assembling plate disposed oppositely to the rear surface of the back electrode, are held in a holder.Electronic circuit elements are attached to only one surface of the circuit assembling plate, and the other surface thereof is faced toward the rear surface of the back electrode with a predetermined distance provided therebetween. A back chamber, defined by a space between the back electrode and the circuit assembling plate, and enclosed by the holder improves the characteristics of microphone frequency response.

A hollow tissue inosculation apparatus is to inosculate two hollow tissues to each other with a staple having a plurality of elastically deformable bent staple pins. The hollow tissue inosculation apparatus includes a staple holder to hold the staple, a curvature control mechanism to control curvature of the staple pins of the staple held in the staple holder, and a gap control mechanism to control gaps of the hollow tissues with respect to the staple holder. The curvature control mechanism substantially straightens the staple pins. The gap control mechanism reduces the gaps to cause the substantially straightened staple pins to penetrate the hollow tissues. The curvature control mechanism and the gap control mechanism are independent from each other.

A conveying mechanism includes: a first belt roller; a second belt roller provided substantially parallel to the first belt roller downstream in the conveying direction of the recording medium; a conveying belt looped over at least the first belt roller and the second belt roller; a belt drive unit conveying the conveying belt; a resist roller pair configured by a first resist roller and a second resist roller contacting the first resist roller; and a resist roller drive unit driving the rotation of the first resist roller or the second resist roller. The first belt roller and the first resist roller are coaxially arranged, and the first belt roller rotates independent of the first resist roller.

摘要:
An operation verifying apparatus of a first embodiment acquires a log indicating the content of a sequence of operations performed on a predetermined device, identifies corresponding functions from the log, and automatically generates a program based on the identified functions. Input data, which is to serve as an argument of each of these functions, is set. Execution sets as well as test scenarios are each structured by combining a program and input data. Then each execution set is continuously executed. As a result, an operation test using a test program is executed.
