Patent JP-H0395477-A (JP)
Title: Ultrasonic detector
Inventor: KAWAGUCHI SHINICHIRO
IPC: G01S15/96
Filed: 1989-09-08
Abstract: PURPOSE:To enhance distance resolving power by detecting the change of the amplitude of an echo by a differentiation circuit and extracting only a necessary signal by a transversal filter. CONSTITUTION:Power of ultrasonic frequency modulated by a rectangular wave is generated in a transmitter 2 and sharp rising and falling characteristics are given to this modulating rectangular wave. This power is converted to ultrasonic wave energy by a transmitter-receiver 1 to be emitted to a target. The emitted ultrasonic wave is reflected by the target to be inputted to the transmitter-receiver 1 as an echo and converted to an electric signal which is, in turn, amplified by a preamplifier 3 and further amplified by a TVG (time valid gain) circuit 4. Subsequently, the amplitude of the waveform outputted from the circuit 4 is detected by a detection circuit 5 and the waveform outputted from the circuit 5 is differentiated by a pulse compression apparatus 6 and only necessary signal is extracted by a transversal filter.

Title: Delivery valve device for compressor
Inventor: KOSOKABE HIROKATSU
IPC: F04B39/10
Filed: 1988-09-19
Abstract: PURPOSE:To improve performance and reliability of a delivery valve by providing an annular groove between the first valve seat surface and the second valve seat surface and a flow path connecting this annular groove to communicate with a delivery hole or a compression chamber. CONSTITUTION:Opening action of a delivery valve 12 is performed by its lifting force generated by a differential pressure between a compression chamber 5a and a delivery chamber 10 inside and outside the valve. Accordingly, the larger is a size D of a valve seat surface the less differential pressure obtains necessary lifting force, and an excessive compression loss is decreased. Then in this delivery valve device, because an annular groove 15 communicates with a delivery hole 11 by a communication groove 16, the size D of the valve seat surface with the differential pressure acting is the first valve seat surface 14a positioned in the outside. Consequently, a relation where Dp<D is obtained decreasing a clearance volume loss further even an excessive compression loss. While even impact force of the delivery valve 12, when it hits the valve seat surface 14, is received by two valve seats of the first and second valve seat surfaces 14a and 14b of almost concentrically circular shape, so that the delivery valve 12 is relaxed in its impact stress.

IPC: G01N23/20
Filed: 1986-09-30
Abstract: PURPOSE:To obtain an evaluating method which facilitates analysis without destroying a sample by using powerful X-rays such as synchrotron radiation X-rays as an evaluation means. CONSTITUTION:The sample has the structure; amorphous Si/Ge0.2Si0.8(111)/Si(111). Incident X-rays are diffracted by the 5X5 interfacial superstructure existing in the several atomic layers at the amorphous Si/Ge0.2Si0.8(111) interface in which the thickness of the amorphous Si is 100Angstrom  and the thickness of the Ge0.2Si0.8(111) is also 100Angstrom .

The synchrotron radiation X-rays are used as the incident X-rays and the sample is rotated by rotating mechanisms 4, 8 of a goniometer at the time of measurement. X-rays have the larger depth of infiltration into solid than electron rays and the destruction of the sample is not required. X-rays are smaller in the scattering sectional area by material than electron rays and the influence of multiscattering thereon is negligible.
