IPC: F23D11/24
Filed: 1983-12-23
Abstract: PURPOSE:To keep the temperature of each of component elements and electronic control circuit or the like which are adjacent within a combustion chamber in an allowable temperature by a method wherein a thermoelectromotive force generated by a first thermoelectric element is utilized as a driving source for the second thermoelectric element, and a generation of thermal flow caused in the second thermoelectric element and its absorption are utilized. CONSTITUTION:A first thermoelectric element 23 to be heated by the flame of a combustion unit 8 and a second thermoelectric element 4 having as its driving source a thermoelectromotive force generated by the first thermoelectric element 23 are arranged at each of the component elements of the combustion device (in particular, a fuel supplying device or atomization device 2) and an electronic control circuit in cooperation therewith. A temperature sensing element orf device for controlling an operation of the second thermoelectric element 4 having as its driving source a thermoelectromotive force is arranged for each of the component elements. With this arrangement, the first thermoelectric element receives a thermal energy from the flame, converts it into an electricl energy. The electrical energy is used as a driving source for the second thermoelectric element and a heat is transmitted from the conjunction part of the second thermoelectric element to other parts. As a result, the heat is transmitted and received between each of the component elements connected to the second thermoelectric elements and an electronic control circuit or the like and so it is possible to control the temperature at its most suitable state.

IPC: B25J9/16
Filed: 1983-12-27
Abstract: PURPOSE:To move assuredly a mobile robot to a desired position with no use of a gyrocompass by correcting the position and direction of the robot every time it passes marks on its path. CONSTITUTION:When a shift is designated to a mobile robot from a position S10 to a position S19, the robot calculates plural courses between the points S10 and S19 from its present position, the position of a caller, map data, etc. Then the shortest course is decided and stored in an RAM17. The stage of the robot is rotated at the position S10 and it is decided whether the robot is set in the direction S10-S11. If the robot is not turned in the designated direction, a belt-shaped mark is detected at the present position of the robot by direction sensors 13a, 13b, 14a and 14b respectively. Then the stage of the robot is rotated more so that the robot is set in the direction Y. When the robot is set in the designated direction, the robot is moved forward until the mark position of the S11. These procedures are carried out successively to move the robot to the target position S19.

Title: Semiconductor memory device
Inventor: FUKUDA MAKOTO
IPC: H01L27/108
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor memory device, enabling a high speed access by interposing a power line at a medium height position between a memory cell and data line or control line on the substrate surface to reduce the noise which is based on drive. SOLUTION: DQ lines 112, /112, CSL lines 113 are laid at cell parts, using a third layer metal wiring 20 to be the top layer. These lines and a second layer wiring 18 to be a lower wiring layer thereof are used for power lines having a large capacitance and little variation. This suppresses the noise from the DQ lines 112, /112 and CSL lines 113 from mixing in word lines, etc., laid by a lower layer, e.g. the first layer metal wiring 20. The noise on the DQ lines 112, /112 and CSL lines 113 varying at cell operation is blocked by the second metal wiring 18, i.e., little variation with large capacitance power lines to thereby block the noise from effecting lower than a first layer wiring 16 and hence obtain a semiconductor memory device operating stably at a high speed.

IPC: G21C3/34
Filed: 1987-09-30
Abstract: PURPOSE:To improve cooling efficiency of a fuel rod and heighten the boiling transition output of nuclear fuel by providing a liquid membrane separating plate in the upstream side of a spacer at which boiling transition is produced and pressing it in the inside of a channel box. CONSTITUTION:A spacer 1 maintains a fuel rod position of a fuel assembly and mutual intervals of fuel rods for a boiling water reactor in which the fuel rods 2 are arranged in approximately square lattice shape. Liquid membrane separating plates 27 are provided in the upstream side of the spacer 1 and pressed and brought into contact on the inner circumferential face 23 of a channel box arranged in the outside of the spacer 1.
