Abstract: PURPOSE:To improve heat-transfer performance, to augment burnout heat flux and to increase the working speed of a semiconductor element by fast sticking a porous layer member as a comparatively thin layer or a member consisting of a roughened surface onto the surface of a columnar heat transfer member integrally formed brought into contact with a heating element and metallically joining the member. CONSTITUTION:When heat is generated from a large number of chip parts 2 dipped in a nonconductive liquid 10 such as a refrigerant, the nonconductive liquid 10 is boiled and foamed 11. The vapor of the liquid is cooled and liquefied 13 by a condenser 12, and collects to the lower section of a sealed vessel 9 again. On the other hand, cavities 3 on the insides of porous layer members 5 brought into contact with the chip parts 2 are shaped in parallel with the axial direction of heat transfer members 6, and heat generated is transmitted quickly over the porous layer members 5 through the heat transfer members 6. When boiling is started, vapor bubbles 20 are shaped extending over a wide range in the cavities 3. The liquid adheres on the inner walls of the cavities 3 at all times and liquid films 21 are formed, and heat transmitted rapidly evaporates the thin liquid films 21. Consequently, bubbles 22 are generated severely from openings 4 and desorbed, and the positions of the bubbles are supplied quickly with other liquids. Heat generated from the chip parts 2 by such a cycle is transmitted efficiently over the nonconductive liquid 10.

IPC: G11C11/409
Filed: 1986-07-01
Abstract: PURPOSE:To prevent a through current from flowing, which results in the damage of elements, by providing a pulse generator circuit generating a pulse with a prescribed width when a power source is entered and forcibly causing 1st and 2nd output transistors nonconductive while the pulse is generated. CONSTITUTION:The pulse generator circuit 10 is provided which generates the pulse with the prescribed width when a power source is entered. If times t0-t2 when the voltage of a node N2 is at a level 'H' are set longer than times t0-t1 when a complementary logical signal D and its inversion D are at low levels 'L', signals DH and DL never become the level 'H' simultaneously even if the inverse of an output enable signal DOE is active (level 'L'), and output MOS transistors 4 and 5 become nonconductive simultaneously. Thus the through current never flows to a grounding GND terminal through the output MOS transistors 4 and 5 from the terminal of the power source Vcc. Consequently the current never damages elements.

Title: Ground maintenance-construction work method and working machine used therefor
Inventor: SEI KENJI
IPC: E01C23/00
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To improve work efficiency by describing a reference plane corresponding to a specified ground construction face, with laser beams, and moving a working machine while moving a uniforming plate of the working machine up and down following the reference plane. SOLUTION: A laser beam emitting part 33 is arranged in an optional position outside of a ground such as a soccer ground face to be an object of maintenance- construction work so as to describe a plane including specified inclination. When a uniforming working machine 60 is towed by a tractor, a laser beam receiving part 31 receives a plane signal H emitted from the laser beam emitting part 33. When a uniforming plate 63 is in a position deeper than specified depth, that is, when the beam receiving part 31 is on the lower side than a reference plane described by the plane signal H, an expansion cylinder 67 is expanded to enlarge a ground angle θof a supporting arm 65A of a press wheel 64 so as to move up the uniforming plate 63.  When the uniforming plate 63 is in a position shallower than the specified depth, the expansion cylinder 67 is contracted to reduce the ground angle θ of the supporting arm 65A so as to move down the uniforming plate 63. Work efficiency is therefore improved.

IPC: C21C5/52
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To promote the melting at a steel tapping hole without developing the erosion of tip part, etc., of a nozzle by using a medium slender nozzle set in a wafer-cooling jacket on the upper wall of the steel tapping hole, blowing oxygen gas in a prescribed term and jetting while aiming in the range from the position just below the furnace wall to a specified % of the furnace inner diameter to the furnace center side from the above position at the molten steel surface height position in the furnace. SOLUTION: The nozzle used is the medium slender nozzle having a throat part at the water-cooling type tip end part and the inclining angle of the nozzle is made to be adjustable and it is effectively that the ultrasonic oxygen gas flow formed with the nozzle is jetted while aiming the position just below the furnace wall at the steel tapping hole side and the range from this position to the 25% of the furnace inner diameter to the furnace center side. Since a gap exists just before the nozzle, the effect of rebound oxygen gas is reduced, and the nozzle part and a structural material around the nozzle are not eroded, and while aiming the boundary between the molten steel pool part and unmelting scrap in the furnace, the oxygen gas can be blown, and the melt-down of heated scrap and the stirring of the molten steel can effectively be executed.
