Title: Modification and/or break down to low molecule of fossil fuel or high molecular material
Inventor: SAITO YOSHIHISA
IPC: C10G1/04
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To modify or break down a fossil fuel, a vulcanized rubber or a high molecular compound by a less expensive method. SOLUTION: A fossil fuel such as coal, oil sand oil, Orinoco oil or shale oil, a high molecular compound containing hetero atoms such as a vulcanized rubber, or a high molecular compound containing no hetero atom dispersed in water is treated substantially in the absence of hydrogen or a hydrogen donor with water of a supercritical state or a subcritical state at high temperature and under high pressure. Thus, the fossil fuel or the high molecular compound such as a vulcanized rubber is modified or broken down to low molecules through hydrocracking attributable to the hydrogen donation from water.

Title: Labyrinth seal
Inventor: SASAKI MASAYOSHI
IPC: F16J15/447
Filed: 1993-11-17
Abstract: PURPOSE:To suppress contact vibration of a rotor when labyrinth fins come into contact with the rotor so that clearance on the tip of the fin may be reduced and the performance of a seal is improved by forming a slit between the axis part of the for and a labyrinth seal, and connecting those components through a neck part only. CONSTITUTION:A clearance existing between a labyrinth seal part 1a protuberantly arranged on the circumference part of a rotor 1 and labyrinth seal fins 2 arranged along its circumference is controlled and pressure difference between a high pressure side H and a low pressure side L is retained. A slit 1c is formed between the labyrinth seal 1a and the axis part 1b of the rotor 1, and those components are connected to each other through a neck part 1d. When the fins 2 come into contact with the rotor 1 during operation, a bend due to exothermic action of the rotor 1 is reduced, and the bend is directed in a direction reverse to the contact part so as to suppress contact vibration. By this process, clearance on the tips of the fins 2 is reduced and the seal performance is improved.

Title: Swing type ultrasonic transducer, method and device for diagnosing osteororsis by using the same
Inventor: ISHII TETSUYA
IPC: H04R1/02
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To exactly estimate the state of bone density and to easily perform high-reliability diagnosis. SOLUTION: A transducer 1 has a main body 101 of transducer for jetting an ultrasonic impulse toward the lower part of the cortical bone as the site to be measured and receiving echo from the lower part of the tibia and a swinging mechanism 102 for changing the jetting direction of ultrasonic impulse without interruption by swinging the main body 101 of transducer within the range of prescribed solid angle. The swinging mechanism 102 comprises an X-axis rotary motor 13 and Y-axis rotary motor 104, the rotary axis of Y-axis rotary motor 104 is rotated by being driven by the drive of X-axis rotary motor 103.  Since an acoustic impedance at the lower part of the tibia to be measured is expressed by the square root of 'elastic modulus × density' of the cortical bone, when the bone density is decreased and the elastic modulus is decreased also, the acoustic impedance is remarkably decreased sensitively in response to these. Therefore, the acoustic impedance of the cortical bone becomes a good index for judging the bone density.

Title: Double window structure body
Inventor: TARUKAWA AKIRA
IPC: G01N17/00
Filed: 1990-11-16
Abstract: PURPOSE:To reduce the influence applied on the transmission characteristic without generating the optical strain on a test specimen inside a double window by forming a passage for gas in a supporting frame and connecting a device for absorbing the pressure variation of the gas in the above-described passage. CONSTITUTION:When the gas sealed by a double window 1 and a supporting frame 2 expands, the expanded portion of the gas 3 passes through a passage device 4 and is sent into a pressure variation absorbing device 5. Accordingly, the device 5 expands, and the pressure variation of the gas 3 is absorbed, and the optical strain of the double window 1 accompanied with the expansion of the gas 3 can be eliminated, free from the deflection of the window 1. On the contrary, since the contracted part of the gas 3 is supplied, passing through the passage device 4 from the pressure variation absorbing device 5, the device 5 is contracted, and the pressure variation of the gas 3 is absorbed, and the optical strain of the double window 1 accompanied with the contraction of the gas 3 can be eliminated similarly without deflection of the double window 1.
