Title: Cylinder block of engine
Inventor: TAKAMORI YUJI
IPC: F02F1/18
Filed: 1989-03-13
Abstract: PURPOSE:To improve a damping function by providing a cylinder liner of a double structure where a damping material is sandwiched between an inside liner and an outside liner, and setting the coefficient of thermal expansion of the inside liner larger than that of the outside liner. CONSTITUTION:A cylinder liner 1 of a double structure is formed by concentrically disposing an inside liner 2 and an outside liner 3. A spiral projecting portion 5 rectangular in section, which is pressed to the inner wall of the outside liner 3, is provided on the outer wall of the inside liner 2. The coefficient of thermal expansion of the inside liner 2 is set larger than that of the outside liner 3, so that when combustion heat is received, a gap between the inside liner 2 and the outside liner 3 is narrowed by a difference in the coefficient of thermal expansion therebetween and a damping material is compressed to increase the density and improve a damping function. Furthermore, shifting of the inside liner 2 to the outside liner 3 is prevented by the projecting portion 5, and heat received by the inside liner 2 is transmitted through the projecting portion 5 to the outside liner 3, so that the cooling ability of the cylinder liner 1 can be improved.

Title: Microanalyzer
Inventor: SATOU MITSUYOSHI
IPC: H01J37/252
Filed: 1980-05-09
Abstract: PURPOSE:To analyze a large-sized sample in a manner to cancel dispersion depending on a position where X-rays pass through solar slits, by a method wherein the solar slits are placed between the sample and a spectral crystal and between the spectral crystal and an X-ray detector, and a division is conducted through the discrimination of an X-ray signal from a continuous X-ray signal. CONSTITUTION:Electron rays e, emitted from an electron gun 1, enter a sample 3 through an electron lens 2 to generate X-rays X1. A spectral crystal 5 is irradiated with the X-rays X1 through a divergent slit 4, and a reflection angle can select X- rays X2 having a given wavelength. The X-rays X2 are detected through a light- receiving slit 6 by means of an X-ray detector 7 to be outputted. The X-rays X1 from the sample 3 are varied depending on the irradiation position of the electron rays e, and said irradiation position causes the movement of a position where the X-rays are allowed to pass through the solar slits 4 and 6 and causes a dispersion of the intensity of X-rays. Said dispersion is cancelled by discriminating the output of the X-ray detector 7 into an X-ray signal and a continuous X-ray signal through a crest value discriminator in an operational path 8 and conducting a division by  means of a divider.

Abstract: PURPOSE:To efficiently display the ability of an entire system in each processor unit by maximizing the frequency using a shared device per hour so as to use said device normally as the total system. CONSTITUTION:If a terminal equipment 3-i-j requests few jobs from each processor unit 3-i and the using frequency of the shared device 1 is less than a critical value, a timer 7 will no start, whereby a counter 5 is reset. Then a terminal equipment interface 4 accepts all the job requests from the terminal equipment 3-i-j. When a using frequency observer 2 detects that the job request from the terminal equipment 3-i-j reaches the limit, the timer 7 starts to release the resetting of the counter 5, and afterward the using frequency of the shared device in each processor unit 3-i is counted. Then the terminal equipment interface 4 rejects jobs from the terminal equipment 3-i-j, and suppresses the using frequency of the shared device 1.

IPC: A61B18/12
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To provide an electric surgical instrument for maintaining a leakage current within an allowable level and preventing the excessive reduction of output power. SOLUTION: A current level difference detection part 51 detects the absolute value of the difference of current levels respectively measured in current measurement circuits 36 and 37 as a leakage current level. A current level difference comparison part 53 and a gain reduction part 54 reduce the gain of the output power when the leakage current exceeds the allowable level stored in a comparison level storage part 52. Thus, the leakage current is maintained within the allowable level. Also, since the reduction of the gain is stopped when the leakage current becomes within the allowable level, the output power is not excessively reduced.
