Title: Flow rate detecting device
Inventor: SASAKI KAZUYUKI
IPC: G01F1/66
Filed: 1989-09-28
Abstract: PURPOSE:To detect the flow rate of fluid by detecting the variation number of a sound pressure amplitude corresponding to the moving speed of the fluid by a detector from a received reflected wave. CONSTITUTION:An ultrasonic wave which is sent by a transmitter is reflected by spot scattering bodies of an infinite number of air bubbles in the fluid to generate reflected waves having a distribution different in sound pressure amplitude with time in a space. When the spot scattering bodies move at this time as the liquid moves, the distribution of the reflected waves also moves at a similar speed. Here, a receiver 3 receives the reflected waves, a detector 4 detects the variation number of the sound pressure amplitude corresponding to the moving speed of the fluid from the received reflected waves, and an arithmetic circuit 7 calculates the moving speed from the variation number to detect the flow rate of the fluid. The transmitter and receiver 3 are put on a tube wall to eliminate the influence of the reflection of the sent ultrasonic wave by the tube wall.

Title: Composite material and manufacture thereof
Inventor: HAMADA TAKAHIRO
IPC: F01D5/28
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To enhance oxidation resistance and heat resistance without use of an anti-oxidation coating by joining an alloy and a ceramic dispersed/reinforced alloy together through an alloy foil. SOLUTION: First alloy powder 3 and ceramic powder 4 are compounded by a mechanical alloying treatment to obtain composite powder 5. Further, the composite powder 5 and an alloy 7 not containing a ceramic with an alloy foil 6 as an insert material sandwiched in between are sealed in a metallic pipe 8 and are subjected to a HIP method to obtain a monolithic composite material 9. In addition, the composite material 9 is stable even in the high temperature region because ceramic particles dispersed in a metallic matrix are not dissolved as solids in the metallic matrix and therefore, is a highly reliable material in terms of oxidation resistance and heat resistance.  Thus a stress generated by the difference in thermal expansion between the alloy 7 and a ceramic dispersed/reinforced alloy is absorbed by the alloy foil 6, so that the joined part is not separated and the composite material 9 obtained shows an outstanding joining strength.

Title: Optical recording medium
Inventor: KAWAMOTO KENJI
IPC: G11B7/24012
Filed: 1990-09-20
Abstract: PURPOSE:To disable direct recording and reproduction on and from a recording layer only by an external recording and reproduction device and to enhance security of the recording content by forming a light shutter layer on a transparent base plate formed on a recording layer. CONSTITUTION:The light shutter layer 1 comprises a reverse photochromic dye, such as an indoline type spiropyrane compound and a binder resin. Since this dye absorbs laser beams in a normal state, the laser beams of the recording and reproduction device is interrupted by the layer 1, or focussed on the layer 1, thus disabling direct reproduction and recording from and on the optical recording layer 3 having recorded information, and further it is made more difficult to focus on the layer 3 by inserting the transparent base plate 2 between the layers 1 and 3. When the layer 1 is irradiated by visible light, the absorption of the layer 1 is changed and the laser beams are not absorbed and recording and reproduction on the layer 3 are made possible. The layer 1 comprises the reverse photochromic dye, and can be restored to the initial condition by leaving it at room temperature for several min.

When the content of the block 7 is inputted, the recognition processing of the keyword of a block 8 is executed by the instruction of the operator. When the recognition of the keyword is succeeded, the other function activation processing of a block 9 is executed. Thus, association with data on the other function can be executed by inputting the simple keyword to the content of the schedule table. Then, data can be read and referred to only by inputting sufficient data and instructing the keyword.
