Inventor: TSUBOUCHI HARUYOSHI
IPC: F02B37/12
Filed: 1977-11-16
Abstract: PURPOSE:To improve the utilization rate of exhaust energy by forming nose section of the volute casing so that the exhaust blows through up to volute starting section of the turbine case in order to increase the force power when the diesel engine is operated at a low-middle speed. CONSTITUTION:Adjustable nozzle 19 is fixed on shaft 11 which is set rotatively in the maze position of turbine case 1. When the engine runs at a high speed and high pressure exhaust air enters the turbine, the high pressure air is also sent from the compressor connected to the turbine to the engine, and part of it enters the pressure chamber 17 of actuator 13 to push diaphragm 14. Since the diaphragm 14 resists the spring force of compressing spring 15 and moves rod 16, arm 12 turns to bring adjustable nose 19 near to runner 5. In this way the putput of the turbine and the compressor outlet pressure are reduced and safety is secured.

Title: Osteoporosis deagnosing device
Inventor: ISHII TETSUYA
IPC: A61B8/00
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To accurately estimate the condition of a bone density and easily perform a highly reliable diagnosis. SOLUTION: A transducer 1 sends continuous ultrasonic waves with which the frequency is swept, repetitively toward the bone of a testee, and receives the echo from the bone. The COS component and SIN component of the given echo are detected on the basis of the received signals (electric signal) and converted into digital signals. From the digitized COS component and SIN component, an inverted Fourier transform is made to remove the transmissive reverberation, etc., and the bone echo waveform is extracted. A CPU 11 extracts the max. echo level among the echo levels, and a Fourier transform is conducted on the basis of the bone echo waveform so that the spectrum is determined, and on the basis of the obtained spectrum, the acoustic impedance of the bone (characteristic) is calculated.  This allows acquiring the amplitude information and phase information, so that accurate diagnosis can be conducted even in case the osteoporosis has propagated and the acoustic impedance of the bone has become smaller than that of a soft tissue.

Title: Acceleration sensor
Inventor: OTSUKI YASUNORI
IPC: G01P15/09
Filed: 1992-05-28
Abstract: PURPOSE:To prevent a piezoelectric element from being broken when an excessive acceleration is applied to an acceleration sensor equipped with the piezoelectric element. CONSTITUTION:Piezoelectric elements 11, 12 and a metallic thin plate 13 constitue a bimorph piezoelectric device. An electrode 11a is used as an output electrode and an electrode 12b serves as an input electrode. When an acceleration is applied to the bimorph piezoelectric device, the detecting voltage at the output electrode is converted to an output voltage at an impedance conversion part 14 and fed to a comparator 16 and a differential output part 17. When a first reference voltage set corresponding to the upper limit of the permissible acceleration is smaller than the output voltage, the comparator sends out a driving signal. The differential output part differentially amplifies a second reference voltage and the output voltage, thereby to generate a differentially amplified voltage. An analog switch part feeds the differentially amplified voltage to the input electrode in response to the driving signal. As a result of this, the distorting force in the opposite direction to that caused by tone impressed acceleration is generated in the bimorph piezoelectric device, and the distorting force applied to the bimorph piezoelectric device is eventually not larger than the permissible limit.
