Patent JP-H0817393-A (JP)
Title: Electric discharge lamp
Inventor: KIRA TAKEHIRO
IPC: H01J61/073
Filed: 1994-06-29
Abstract: PURPOSE:To achieve increase in strength, enhancement of fabrication efficiency and cost reduction by arranging polygonal thin plates made of a high melting point metal inside branch pipe portions provided on both sides of a bulb, and passing lead boars through the thin plates. CONSTITUTION:Branch pipe portions 2 are joined to a bulb 1, and lead bars 4 are passed through sealing portions 3 at both ends of the bulb, and an anode 5 and a cathode 6 are attached to the ends. Both sides of each supporting member 8 made of a high melting point metallic plate through which the lead bar 4 is passed are secured to the lead bar 4 by a fine Mo coil. Each supporting member 8 is made of a thin Mo plate in the form of a regular polygon with a lead bar hole bored with precision. Since the square thin plate is curved, each supporting member is brought into secure contact with the inner surface of the branch pipe portion because of its elasticity. The gap between each side of the supporting member and the inner surface of the branch pipe portion 2 allows gas to flow between the supporting member 8 and the sealing portion 3. Therefore, an evacuation period is short, degrees of vacuum are increased, and the long lead bar 4 supported at two points at the sealing portion 3 and the supporting member 8 increases impact resistance; also, since heat welding is not performed, no impurity gas is generated within the pipe, and thus long life is ensured.

Title: Method and device for preventing pitching of hull
Inventor: ISHII AKIYOSHI
IPC: B63B39/06
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent the pitching when a ship is stopped by reciprocating a strut having a hydrofoil at its forward end in the diagonal direction with the reverse phase to the pitching phase of a hull. SOLUTION: A strut 2 fitted with a hydrofoil 3 on its forward end is provided diagonally at the prescribed angle θ relative to a ship bottom 1b of a hull 1, and fitted to a driving mechanism 5 in the hull 1. The driving mechanism 5 is provided with a cylinder mechanism 5a as an example, and the strut 2 is elevated/lowered in the diagonal direction. A control part to control the driving mechanism 5 receives the pitching information of the hull from an list sensor and an acceleration sensor by the signal, and the driving mechanism 5 is driven with the reverse phase to that of the wave. When the right end of the hull 1 is turned in the sinking direction, the hydrofoil 3 is moved downward so as to apply the resistant force. When the left end of the hull 1 is turned in the sinking direction, the hydrofoil 3 is moved upward so as to apply the resistant force.

Abstract: PROBLEM TO BE SOLVED: To improve the quality and the casting efficiency of a cast product with a die casting method. SOLUTION: Molten metal is poured from a pouring hole 52 in the opening state in a cavity 30 of a die 20 in a die casting apparatus to the atmosphere. A plunger tip 70 is advanced at a low speed to close the pouring hole 52, and a communicating path 58 is communicated with a vacuum device 62 by changing over switching valve devices 120, 142 to evacuate the cavity 30. After passing a setting time, oxygen is supplied into the cavity 30 from an oxygen supplying device 64 by changing over the switching valve device 120. During this operation, too, the plunger tip 70 is advanced at the low speed. The oxygen is filled in the cavity 30 and just before pushing the molten metal into the cavity 30, the advance of the plunger tip 70 is made to high speed.  At the end stage of filling the molten steel into the cavity 30, the communicating path 58 is opened into the atmosphere by changing over the switching valve devices 120, 142. Entrapment of the air into the molten metal is restrained and also, the casting time can be shortened.

At vacuum holding and exposing, the belt 48 and the bending member 100 are substantially made horizontal by a vacuum force formed on the belt bending member 100, simultaneously, the rear side of the belt 48 is pushed by the force so that it may be horizontal to the photosensitive material and a platen 22. The uniform back face is formed on the rear side of the belt 48 in such a way without substantially projecting at exposure. Thus, the fluctuation of the reflectance is prevented.

Title: High power semiconductor device with integral heat sink and forming method therefor
Inventor: ROBAATO JIEI UEBAA
IPC: H01L23/34
Filed: 1991-07-10
Abstract: PURPOSE: To obtain a built-in type heat sink for semiconductor with a high efficiency by allowing a micro channel heat sink to have a cooling fluid source. CONSTITUTION: A micro channel heat sink 20 is directly formed on an A/N thin film 16. The micro channel heat sink 20 has a plurality of relatively thin grooves 22 and the grooves 22 are positioned relatively close to the surface of the heat sink 20 in contact with the A/N film 16. The cooling fluid source 25 is circulated via the grooves 22 as shown by an arrow 26. A coolant 25 contacts the relatively large surface area of a groove wall when crossing the groove 22, absorbs and eliminates heat, and is propagated to the heat sink 20. Heat generated on a surface 12 of a semiconductor device is rapidly propagated via the A/N thin film 16 and reaches the heat sink 20 made of copper. Then, the cooling fluid 25 passing through the groove 22 absorbs and carries away heat, thus operating a semiconductor while maintaining a junction temperature in a semiconductor at an allowable level.
