Patent JP-S5790589-A (JP)
Title: Heat accumulating device
Inventor: NOMURA KAZUO
IPC: F28D20/00
Filed: 1980-11-22
Abstract: PURPOSE: To contrive to prevent nuclide from sedimentation, to accelerate crystallization and to stabilize heat release of heat accumulating material by a constitution wherein the nuclide with crystal depositing function and the latent heat accumulating material are held in carrier and filled up in a shell.  
     CONSTITUTION: The latent heat accumulating material containing the nuclide with crystal depositting function is impregnated in a foamed substance 1 with continuous foams 2 such as foamed urethane or the like and then housed in the shell 3. Owing to the constitution as described above, even when the latent heat accumulating material melts by absorbing the heat, the nuclide remains to be carried and held in the foams 2 without being sedimented to the bottom of the shell 3. Consequently, the nuclide is kept in a properly dispersed state. Accordingly, even when the crystallization of the nuclide occurs through the heat release of the latent heat accumulating material followed with the drop of temperature, the crystallization occurs and proceeds in dispersed state because of the dispersed state of the nuclide. As a result, the quick and stable heat release can be resulted.

Inventor: SAITO MASAJI
IPC: F28F19/02
Filed: 1985-07-26
Abstract: PURPOSE:To obtain the fin material for heat exchanger, excellent corrosion resistance, hydrophilic nature, continuous molding and chemical resistance, by forming an anticorrosion film on the surface of an aluminum thin sheet and a coating layer, consisting of organic compound having hydrophilic nature and chrome compound, on the film. CONSTITUTION:When crosslinking reaction between the chrome compound and the hydrophilic base of organic compound, which constitute the coating layer formed on the upper layer of the anticorrosion film, is caused, the corrosion resistance of the material can be improved without sacrificing a desired hydrophilic nature. Chemical resistance may also be improved by polymerization. On the other hand, the chrome compound exists in the coating layer as part of the reaction, product, therefore, the property of continuous molding, which is essential for the organic compound, will never be deteriorated. Further, in case the anticorrosion film of the lower layer is treated into chromate treated film, the corrosion resistance can be increased by the interation such as crosslinking reaction resistance or the like between the chrome compound in the treated film and th eorganic compound in the upper layer whereby the anticorrosion characteristic, higher than the total sum of the effects by both layers, can be obtained.

Filed: 1994-07-18
Abstract: PURPOSE:To improve workability by providing a falling stone preventive protector covering the circumference of a connecting part pit mouth of a pile tunnel against a main tunnel working face surface and extending to its rear part side in the case of drilling the pile tunnel and the large sectional main tunnel in translation. CONSTITUTION:Drilling work and taking-out work by a tunnel boring machine are sequentially carried out on the side of a pile tunnel 1. Thereafter, working face surfaces 2a, 2b are drilled by a drilling machine 8 of a gantry type multifunctional jumbo 4 on the side of a main tunnel 2. After planting a blasting compound for drilling, the jumbo 4 is retreated, the working face surfaces 2a, 2b are crushed, while mucking work is repeated. At the time of blasting work, crushed stones are scattered and accumulated in the neighbourhood, but as the inside surrounded by a falling stone preventive protector 11 is protected, the mucking work in a pilot tunnel 1 is never suspended. Consequently, it is possible to prevent interference of both of the tunnels, to safely carry out construction simultaneously and in progress and to speedily construct a large sectional tunnel.

Title: Suction pressure detecting device of internal combustion engine
Inventor: KIGAMI KATSUHIKO
IPC: F02D45/00
Filed: 1987-07-03
Abstract: PURPOSE:To make it possible to eliminate the pulsation of the detecting signals when a supercharger is operated, without deteriorating the transient response by selecting the amount of the filter constant at a filter which tempers the suction pressure detecting signals responding to the operational condition. CONSTITUTION:In a suction pressure detecting device 7, at least the supercharging operational condition of the operational conditions of an internal combustion engine 8 is decided by the detecting signals from a supercharge dectector 3 and an idling detector 4 at an operational condition deciding unit 5. At a filter constant setting unit 6, responding to the result of the above decision, the filter constant is made smaller in an ordinary operational condition, made larger in the idling operational condition, and made further larger in a supercharging operational condition, for example. Consequently, in the internal combustion engine 8 with a supercharger 9, the detecting signals from a suction pressure detector 1 are tempered at a filter 2, and a constantly stable suction pressure signal can be obtained thereby.

Title: Learning control method

IPC: G05B19/4155
Filed: 1983-09-08
Abstract: PURPOSE:To improve greatly the positioning accuracy for each posture of a robot by measuring the dynamic delay time for each degree of freedom and adding a deviation to the target value earlier by an amount equivalent to the obtained dynamic delay time for operation of reproduction. CONSTITUTION:The target value R1 is sent at a starting time point of control to measure the time T1 during which a repdocution locus Y of a mobile element reaches the position of the R1. The time T1 is counted to obtain the value of multiple compared with a control cycle T0. Thus a delay time m(=5) is obtained. When the measurement is through with the time (m), the time during which a locus Y12 is equal to or larger than the target value R6 is measured from the transmission of the value R6 of that time point. Then the time (m) is counted. As the difference epsilon6 between the locus Y6 corresponding to the value R1 and the value R6 of that time point is equal to a deviation due to a dynamic delay, this difference epsilon6 is added to the value R1 which is earlier by an amount of (delay time 5XT0) to obtain the new target value R'1. In the same way, a difference epsilon7 is added to the target value R2 to obtain the new target vlue R'2. Then target value R'3 and so on are calculated to use them as target values in the following reproduction modes.
