Abstract: A technique includes at least one chamber including a process chamber that is capable of processing a substrate and a shower head arranged in an upstream of the process chamber; a gas supplier that is capable of supplying a gas into the process chamber via the shower head; a first exhaust pipe communicating with the shower head; a second exhaust pipe communicating with the process chamber; a first exhaust controller installed in the first exhaust pipe; a first heater installed in the first exhaust pipe; and a controller configured to be capable of: (a) controlling the gas supplier so as to supply a processing gas as the gas to the shower head, and (b) controlling the gas supplier so as to supply a non-processing gas as the gas to the shower head.

Abstract: A non-invasive (having sufficiently small diameter so as not to give much pain to a subject) ultrasonic ultrasound probe of high spatial resolution and high signal-to-noise ratio, an ultrasonograph using the probe, and an ultrasonography are provided. The ultrasound probe is inserted into the tissue under examination and transmits an ultrasonic wave.

Abstract: An IC card issuer issues an IC card and requests a card memory area operator to lend part of a memory area of the IC card to another card memory area user. The card memory area operator provides a memory area division apparatus and various data to the memory area division apparatus under the control of an operator communication apparatus 12. The card memory area user divides the memory area of the IC card into a memory area to be used by the IC card issuer and a memory area to be used by the card memory area user. The operation file registration apparatus writes file data for the card memory area user to the memory area of the card memory area user obtained by the above division.

Abstract: The present invention relates to an ultrasonic motor comprising a stator formed by using an acoustic waveguide of helical coil shape or an acoustic waveguide of in-plane spiral coil shape, so that a rotor placed in close proximity to, or in close contact with the coil is rotated, traveled, or performed curved line movement by the propagation of the wave on the stator, thereby eliminating the provision of a preload spring and an absorber, simplifying the structure of the motor, reducing the size of the motor, and enabling to work in a liquid environment without water proofing and rotation of a hollow tube.

Abstract: An ultrasound wave is transmitted from a probe (120) to a moving reflector (130) and the reflected ultrasound wave is received back by the same probe (120). With n-divided wave bands of the to-be-used spectrum, the ultrasound wave to be transmitted is made up of up chirp signals and down chirp signals from n number of down chirp signal generators (112, 113) and up chirp signal generators (116, 117), creating complementary multiplexed chirp signals through synthesizers (114, 118). Cross-correlation is taken by a correlator between the reception signal received at the probe (120) and the up chirp and the down chirp signals, respectively, so as to provide compressed up and down signals and then combining the obtained compressed signals through synthesizers (144, 148). Doppler measurement is performed by determining the correlation distance through taking the cross-correlation between these compressed signals by a cross-correlator (160) and performing envelope detection by an envelope detector (170).

Abstract: As shown in FIG. 2(a), according to the present invention, a quartz rod is used where, for example, the diameter of the end on the side to which an ultrasound probe attached is 0.58 mm, the diameter at the narrowest portion is 0.3 mm, the diameter at the end on the specimen side is 0.68 mm, and the length is 38 cm. As a result, the diameter on the side of fused quartz rod 20 to which ultrasound transducer 10 allows a favorable range of L (0,3) mode conversion efficiency; and in addition, the diameter of quartz rod 20 on the side coming into contact with specimen 50 is sufficiently large in comparison with wavelength, and in other portions it is set to be sufficiently narrow in order to obtain flexibility. FIG. 2(b) shows a transmission and a reception waveform.

Abstract: A transmission unit to transmit an ultrasonic wave into a body and a medical treatment/diagnostic apparatus having the same. The transmission unit includes a fiber and a protective layer on a periphery of the fiber to prevent breaking due to surface cracks in the fiber during bending. Thus, the transmission unit can be inserted into the body through curved passages such as the urinary tract. The transmission units may be bundled to increase a power of the ultrasonic wave.

Abstract: A test device for burn-in tests of semiconductor packages. The device includes a printed circuit board provided with openings or frames for receiving the semiconductor packages to be tested and aligning the package lead with circuit board terminals. A cover plate provided with elastic bodies on a back side thereof is used to concurrently elastically press all of the leads and terminals into electrical contact. In one embodiment, elastic connectors having thin metal wires embedded therein are provided in the openings or frames to electrically connect the leads to the terminals when the cover plates is pressed downwards on the semiconductor packages.
