Inventor: HAYAZAKI YASUICHI
IPC: F16H63/02
Filed: 1986-08-01
Abstract: PURPOSE:To always keep the adjusted pressure at a prescribed value by installing the branched point from a pressure adjusting circuit of a control pressure circuit onto the downstream side of a filter for working fluid. CONSTITUTION:A pilot pressure circuit 13 is branched at a branched point 13a and connected as control pressure circuit 18 with the chamber 11c of a pilot valve 11. An oil filter 20 is inserted into the upstream side of the branched point 13a to a control pressure circuit in the pilot pressure circuit 13. In other words, the branched point 13a is positioned on the downstream side of the oil filter 20. Therefore, even if the oil filter 20 is clogged with dusts, etc., and the pressure loss is increased, the generated reduction portion of the pilot pressure PP can be compensated, and the inadvertent reduction of the line pressure can be prevented by keeping the pilot pressure PP always at a prescribed value.

IPC: F02P23/04
Filed: 1982-10-16
Abstract: PURPOSE:To improve combustion efficiency and to prevent knocking by firing mixed gas through insulation breakdown due to high frequency electromagnetic field having inherent exciting mode formed in a combustion chamber. CONSTITUTION:High frequency electromagnetic wave led through an antenna 8 into a cylinder will produce inherent mode (excitation mode) in a space to be formed with a piston and a cylinder. In the modes (a), (b), the point where the strength of electromagnetic field will be at the maximum exists in the vicinity of A and B. Various modes can be excited more strongly by determining such that the inherent wavelength in the cylinder to be determined by the shape of combustion chamber formed with a cylinder head and piston will match with the wavelength of electromagnetic wave. The high frequency electromagnetic field is very strong at or near the central portion of cylinder than the circumferential wall and if it is sufficiently strong, it will cause insulation breakdown in the cylinder to fire mixed gas in dot, line or face shape.

Title: Damping structure in high-rise structure using impact damper
Inventor: FUJITA SATOSHI
IPC: E04H9/02
Filed: 1994-07-08
Abstract: PURPOSE:To damp the vibration of a high-rise structure utilizing impacting energy by providing two additional weights on or in the structure and fixing a stopper midway in the moving region of the weights. CONSTITUTION:A dynamic damper D of two degree-of-freedom comprising two additional weights having mass m1, m2 is provided on or in a high-rise structure having mass M. And a stopper 5 which is adjusted to a predetermined rigidity lower than that of a structure 1 is fixed to the structure 1 at the point midway in the moving region of the weights 2, 3. When amplitude of the structure is small, the weights 2, 3, as a pair of weights, impart reaction forces in a direction such that vibration acting on the structure 1 is eliminated so that normal function of a dynamic damper will be produced. When amplitude becomes larger, the weights 2, 3 move independently and run against the stopper 5 successively at small time differences so that a large amount of impacting energy is produced and hence the vibration of the structure 1 is absorbed and a vibration generator is driven precisely.

Title: Scintillaltion detector
Inventor: MURAKAMI KAZUHIRO
IPC: G01T1/20
Filed: 1986-07-31
Abstract: PURPOSE:To always perform the best imaging, by subtracting a signal, which is obtained by applying predetermined weighing to the output signal of an integrating circuit, from an energy signal. CONSTITUTION:When gamma-rays are incident, the light emitted from a scintillator 1 is sent to a position operating circuit 5 through PMTs(photomultiplier tubes)3 and preamplifiers 4. Further, the outputs of PMTs3 are added by an adder circuit 6 through the preamplifiers 4 to obtain the energy signal E0 corresponding to incident gamma-ray energy. The circuit 6 makes input resistors 62, 63... equal and adds all of the outputs of PMTs3 with equal weighing. The signal E0 is integrated by an integrating circuit 7 to obtain an integral signal -Ei reversed in polarity. This signal -Ei is added to the signal E0 by an adder circuit 8 and, since the polarity of the signal -Ei is reversed to that of the original input signal, subtraction is performed as a result. The input resistor 82 of the circuit 8 is a variable one and, by adjusting said resistor, weighing with respect to the signal -Ei can be changed. A peak analyzer 9 discriminates whether on not the output signal Ec of the circuit 8 has entered a predetermined energy window.

Title: Ceramic passage for yarn
Inventor: SOROE KAZUNORI
IPC: B65H57/24
Filed: 1980-12-16
Abstract: PURPOSE: To prevent fiber yarn from fluffing and snapping, by making a passage for guiding the fiber yarn, of polycrystalline ceramic whose aluminum oxide content is 96% or more and whose crystal grain diameter in 15μ or less.  
     CONSTITUTION: A passage for guiding natural or synthetic fiber yarn or the like in its manufacturing or processing is made of crystalline ceramic whose aluminum oxide (alumina) content is 96% or more and whose crystal grain diameter is 15μ or less. To manufacture the passage, a solid sintering method of effecting high-temperature sintering with an extremely small quantity of a sintering assisting agent or without it to diffuse the alumina crystals from one another for direct combination is adopted. Since vitreous substances are hardly present between the alumina crystals of the alumina ceramic, a desired high degree of purity is attained. Therefore, the wear of vitreous substances and the dropping- off of the alumina crystal grains due to said wear are avoided.
