Title: Online acoustic densitometry apparatus used with ultrasonic imaging apparatus
Inventor: OORUUIN PII DEIISA
IPC: G01S7/52
Filed: 1993-03-30
Abstract: PURPOSE: To eliminate nonlinearity induced in a video image by compression or gray scaling of ultrasonic data. CONSTITUTION: This invention is to provide a mechanism to select plural pixels in a designated range of two-dimensional ultrasonic image by an ultrasonic imaging device, which can generate conventional envelope detected acoustic data and/or integrated acoustic backward scattering data. A value of each image element is processed and the average acoustic intensity 80 of the selected pixels is obtained. The average value is processed by the processes of 82, 84, 86, 90, 92 and 94, and the nonlinearity between the calculated average value and originally received acoustic signals is eliminated. This nonlinearity can be induced by compression, scaling and mapping of data, which are used in generating data for a conventional video monitor.  The processed average acoustic density is plotted, and the process is repeated at prescribed time intervals, and the time-density characteristic curve of originally received acoustic signals and a linear relation is formed. By calculating the characteristic of the curve, translated information related to an ultrasonic irradiated human body and the contrast medium existing inside are provided.

Patent JP-H08275263-A (JP)
Title: Overcurrent protection device
Inventor: OTSUKA JUNJI
IPC: H02H7/12
Filed: 1995-03-29
Abstract: PURPOSE: To identify a state between connection terminals at a low cost with high accuracy by selecting a state of a semiconductor switch depending on a voltage between a connecting point of 2nd and 3rd resistors and a connection terminal of a 1st resistor connection side. CONSTITUTION: When connection terminals are almost in a shortcircut state while a semiconductor switch element 1 is conductive, since a voltage drop by a 1st receiver 2 is high, a voltage E between a connecting point (m) of 2nd and 3rd resistors 3, 4 connected in parallel with the semiconductor switch element 1 and the connection terminals 8 toward the 1st resistor connection side gets higher, an overcurrent detection circuit 5 switches the semiconductor switch element 1 to be open thereby limiting a current flowing to the connection terminals 8. In this state, the overcurrent detection circuit 5 monitors the state of the connection terminals 8 on the basis of the voltage E between the connecting point (m) of 2nd and 3rd resistors 3, 4 connected in parallel with the semiconductor switch element 1 and the connection terminals 8 toward the 1st resistor connection side.  Since the voltage E is decreased when the state of the connection terminals 8 restores to a normal state while the semiconductor switch element 8 is open, the over current detection circuit 5 selects the semiconductor switch element 1 to be conductive thereby releasing the overcurrent protection.

Title: Controller of electric rolling stock
Inventor: NODA TOMOHITO
IPC: B60L15/22
Filed: 1990-03-23
Abstract: PURPOSE:To conduct a reverse rotation always correctly by equipping a self- holding circuit composed of an auxiliary cam and auxiliary relay for continuously rotating a reversing shaft to the first command position, when power is turned OFF immediately after the reversing shaft has been switched to command a forward travel or reverse travel. CONSTITUTION:When a reversing shaft RV is switched from R position to F position and a master controller is closed in a driving cab unshown in the drawing, a reversing relay RVR and auxiliary relay RVR2 operate through a path (a). When the RV shaft is in the R position, a relay KC1R operates and an auxiliary cam contactor KC1 is held by an auxiliary cam contactor KC5. Therefore, even if the master controller is turned OFF immediately after the F position has been commanded, the reversing relay RVR and auxiliary relay RVR2 are not turned OFF but self-held so that the RV shaft continues to rotate from the R position to the F position and a reverse rotation is conducted accurately, until the RV shaft reaches the F position. Operation is conducted in like manner also at the time of the reverse rotation from the F position to the R position. Thus, the RV shaft is prevented from stopping halfway to make the start thereafter impossible.

A relative position detecting means 124 determines the relative mispositioning rate a from the left edge of the frame to the blip. A stop position setting means 112 calculates the sum L0 of the relative mispositioning rate (a) and a specified value (b) and determines the sum L0 as the blip stop position based on the left edge of the reading range. A feed control means 108 feeds and stops the film 26 until the present position L of the blip is aligned to this blip position L0 . Consequently, the image of the frame is eventually stopped at the adequate position apart by the distance (b) from the left edge of the reading range.

Abstract: PURPOSE:To enable accurate inspection regardless of variations in inspecting conditions, by sampling image data at a dish section to set a threshold based on the data. CONSTITUTION:A plurality of data at a dish section 3 are sampled from among multilevel image data generated and the multilevel image data are binary coded at points on an end face 2 by a threshold Dt set based on the data sampled to generate a binary coded image 6. In the binary-coded image 6, the position O of the center point of the disk section 3, namely, the center point of a pellet 1 is checked to measure the number of data existing in an area 11 containing the center point O. As the area 11 containing the center point O of the dish section 3 corresponds to the normal part naturally, the number of data in the area 11 is regarded as the number of data at the normal part and hence, the area 12 other than the area 11 can be a defective part. Thus, the number of data in the area 11 is collated with a criterion reference value preset to decide on the quality, the acceptance or reject, of the pellet 1.
