Title: Ultrasonic observing device
Inventor: KAMI KUNIAKI
IPC: A61B8/12
Filed: 1991-01-18
Abstract: PURPOSE:To output an image signal suitable to signal analysis with respect to gain, contrast, and STC to perform image analysis by ultrasonic observed image data. CONSTITUTION:The observed output of an endoscope is inputted to a gain, contrast, and STC regulating circuit 3 regulated by an observer through a transmitter-receiver circuit 2. The output is processed by a wave detecting circuit 4 and an A/D converter 5, and then stored in a frame memory 6. At the time of observing the image, the stored data is outputted to a monitor 14. On the other hand, at the time of image analysis, the image data in the frame memory 6 is subjected to data converting processing in which the amount regulated and changed in the regulating circuit 3 is returned to the original value in a data converting circuit 9. The converted output is outputted to an output terminal part 15 for external image analyzing device.

IPC: B60K15/077
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To improve the sealing property in the joint of a resin layer and an inner parts. SOLUTION: Triangular notches 36, 38 are formed at the base of a separator 16 in a joint 34 of the separator 16 and a resin layer 30 and gas barrier sheets 32 are arranged at the bottoms 36A, 38A of the notches 36, 38.

IPC: H01L27/04
Filed: 1980-01-21
Abstract: PURPOSE:To make a wiring capacity small by providing p type region on n type Si substrate, forming a depletion layer and forming a wiring layer on a substrate surface on the depletion layer through an insulating film. CONSTITUTION:p<->-Wells 7 are formed in the n<-> type Si substrate 6 applied a positive substrate potential. Elements of MIS transistor and the like composed of n<+> layer 8 are formed in the p<->-wells 7. The p<->-wells 7 are separated each in a region where the wiring 9 is formed, and the depletion layer 10 extends to the n<-> type substrate side in the region. If an interval between the wells is narrow, the whole separated region tends to be depleted and the depletion layer thickness (d) viewed from the substrate surface is made more than the depth of the well. Accordingly, the wiring capacity decreases in large without making the SiO2 film 11 thick, because the capacity of the depletion layer is small to the extreme out of the composite capacity of the capacity of the film 11 and that of the depletion layer. Accordingly, high speed operations are made practicable.

Title: Multistage hydraulic machine
Inventor: HISHIDA YASUO
IPC: F03B3/18
Filed: 1980-01-21
Abstract: PURPOSE: To surely open and close the plural-stage movable guide vanes of a hydraulic machine synchronously with each other, by coupling the guide vane stems of all stages to each other to provide a single servomotor operation mechanism.  
     CONSTITUTION: The stems of the first-stage guide vane 7 and the second-stage guide vane 8 are coupled with each other by a connecting member 17. Although the connecting member 17 extends through a return vane flow passage 5, the member 17 is not located in the space of the passage 5 and neither reduces the cross section of the flow passage 5 nor disturbs the flow becuase the connecting member 17 is inserted with an appropriate clearance between openings 5B provided in a return vane 5A. For that reason, the guide vanes in all the stages can be simply and surely opened and closed synchronously with each other by a single servomotor through a lever 9 etc.

Abstract: PURPOSE:To make possible the wirings in accordance with a scale of semiconductor device type without increasing of chip size by providing wiring cells consisting of plurality of wirings which connect majority of wirings in the interelement wiring region in a part of element mounting region of the surface of a semiconductor substrate. CONSTITUTION:A wiring cell 9 having plurality of wirings 8 connected to majority of wiring 7 of the wiring channel (inter element wiring region) 6 is provided at a part of the basic cell train 4. Therefore, even when a number of wirings larger than the limit of wiring 7 of channel 6 is required, from a scale of the type applied, a master slice IC having the desired functions can be obtained by connecting excessive wirings 7 in the channel 6 with the wiring 8 of the wiring cell 9 without widening the width of channel as in the case of conventional device. In an IC chip, elements of about 20-30% are not used and therefore wiring channel width becomes insufficient in at most several areas and such phenomenon occurs only at a part of channel 6. Therefore, this method does not restrict the application range of the product.

A voltage delay circuit 6 supplies the effective real electric power and detects the power supply voltage every fixed time interval T to store a fixed number of voltage signals by a voltage memory means. Then the circuit 6 inputs the voltage signal (e) at a time point t6 and outputs the voltage value obtained at a time point t4, for example, having a small time delay from the point t6 as the voltage command value e* in case of the small effective real power.

Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a controller for motor which can prevent the creak of gears even under a condition such that the load of a DC motor becomes smaller and is controlled with a zero current. SOLUTION: A controller for motor is provided with a level detector for detecting the level of a current feedback signal from a current detector 13, which detects the current of a DC motor 5.

Abstract: PURPOSE:To improve the focus detecting sensitivity by setting two faces of a beam splitter which correspond to an objective lens so that these faces are positioned vertical to the optical axis of the lens and using at least a part of the face of the divider set more distant from the objective lens as a reflector. CONSTITUTION:The two faces of a beam splitter 2 which correspond to an objective lens 4 are set vertical to the optical axis of the lens and at least a part of the face more distant from the lens 4 is used as a reflector 6. In other words, the luminous flux emitted from a semiconductor laser 1 is turned by 90$ by the half mirror surface 3 of the splitter 2 and then made incident on the lens 4 to be converged on an information recording surface 5 in the form of spots. The luminous flux reflected on the surface 5 is turned again into the focused light through the lens 4 and passes through the surface 3 of the splitter 2 to be reflected by the reflector 6 set on the single face 2a of the splitter 2. This reflected light changes its course again on the surface 3 and is incident on a photodetector 7. In such a constitution, the focus detecting sensitivity is improved.

Abstract: PURPOSE:To allow display apparatuses to display a plurality of operating conditions of the hot water supplier by lighting respective display apparatuses in accordance with a change in a voltage or a current supplied to a remote controller from the hot water supplier through a transmission line. CONSTITUTION:When a hot water supplier 1 starts its operation and combustion is started, a control circuit 7 operates and a second output terminal B outputs a low-level signal in place of a high-level signal. For this reason, the inter-terminal voltage of a third resistor 16 becomes high and a high voltage is supplied to a remote controller 6. A regulate diode 25 becomes conductive, and a combustion display lamp 26 is lit. Upon this occasion, an operation lamp 28 is continuously lit. A current in accordance with a set value of a variable resistor 23 flows and a voltage drops in accordance with the current appears at a current detecting resistor 18. The control circuit 7 operates in accordance with this voltage and the temperature control of hot water supplied from the hot water supplier 1 is carried out. When an operation switch S is turned off, a current does not flow from the remote controller 6 to a current detection resistor 18, the control circuit 7 operates and the operation of the hot water supplier 1 is stopped. Further, in a case where a fault or the like occurs in the hot water supplier 1, the control circuit 7 acts and the combustion display lamp 26 flashes.
