Title: Measuring tool for low-speed fluid of magnetic resonance device and low-speed fluid measuring method using same tool
Inventor: KIMURA TOKUNORI
IPC: A61B5/055
Filed: 1990-06-29
Abstract: PURPOSE:To improve the detection sensitivity at the time of measuring the flow speed or flow rate of the low-speed fluid passing a slice surface through the operation of a flow rate increase part by providing the measuring tool with the flow rate increase part which is of size corresponding to the unit voxel of the slice surface and increases the flow rate density of the low-speed fluid. CONSTITUTION:The measuring instrument is equipped with the flow rate increase part which is formed in a small-diameter tube shape to the size corresponding to the unit voxel of the slice surface and increases the flow rate density of the low-speed fluid. Consequently, when the flow rate increase part is put in scanning operation by the magnetic resonance device, the detection sensitivity of the low-speed fluid is larger than before. When this low-speed measuring method is employed, the sensitivity of the magnetic signal obtained by putting the flow rate increase part in the scanning operation is large, so processing is carried out according to a specific pulse sequence to securely find the flow speed or flow rate of the low-speed fluid from a body to be measured.

Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of warpages due to temperature change, and to improve reliability in a semiconductor device that is constituted of a plurality of materials with different thermal coefficients of expansion, and its manufacturing method. SOLUTION: A semiconductor device is provided with a semiconductor element 22, a wiring substrate 23 where the semiconductor element 22 is mounted, a metal frame 24 where an element accommodation hole 29 placed on the wiring substrate 23 is formed, a sealing resin 26 for sealing the semiconductor element 22 that is filled into the element accommodation hole 29 of the metal frame 24, and a heat sink 25A that is provided at the upper portion of the metal frame 24, so that it covers the element accommodation hole 29. In the semiconductor device, the heat sink 25A is formed by an elastically deformable material and at the same time is constituted so that an elastic recovery force toward an upper portion can be accumulated in the heat sink 25A.  Then, the sealing resin 26 is energized upward by the elastic recovery force, thus suppressing the generation of warpages caused by the difference in the thermal coefficient of expansion of each component in the semiconductor device.

Title: Speed governor for diesel engine
Inventor: AONO HIROSHI
IPC: F02M59/44
Filed: 1983-09-19
Abstract: PURPOSE:To prevent overload driving from occurring in time of travelling, by making a regulator handle of a governor into a two-in-a-set pair, while linking them up with a fuel decrement lever at a time when one side of handles exceeds a certain range. CONSTITUTION:A two-in-a-set pair of handles 3 and 4 are pivoted on a regulator handle shaft 2 of a governor. At operation, when the handle 4 is turned round, a pressing piece 16 secured to the second handle 4 presses a support piece 14 secured to the first handle 3, making the first handle 3 turn round, thus a speed increases. At travelling, when the first handle 3 is turned round, the speed is therefore increased but if it exceeds a certain range, a screw 15 attached to the support piece makes a fuel decrement lever 19 shift in a decrement direction. Thus, fuel is made so as not to be shifted to the increment side beyond the certain range so that overload driving is preventable from occurring in time of travelling.

IPC: G02B6/44
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To easily mount an optical fiber by constituting a jacket part provided on the outer periphery of a clad with a highly flexible material. SOLUTION: In an optical fiber 10, cores 11 are arranged in a grating manner with a fixed interval in a clad 12. The diameter of the core 11 of the optical fiber 10 is e.g. 75 μmϕ to the diameter 1 mmϕ of the clad 12 and the core 11 is constituted so as to enable image transmission by arranging many cores in a grating-like manner.
