Title: Air-bleed device of pump suction pipe system
Inventor: MIYATA NORIHISA
IPC: F04B53/06
Filed: 1983-04-29
Abstract: PURPOSE:To suck and feed liquid, efficiently, by connecting an air chamber through an air-bleed valve chamber to a liqid pump suction pipe system in a part where air accumulation is brought about, and as well by self-sustaining the inside of the chamber in a negative pressure range. CONSTITUTION:An air chamber is connected through an air-bleed valve chamber to a liquid pump suction pipe system in a part where air-accumulation is brought about inside of a pipe, and the inside of the chamber is self-sustained in a negative pressure range. For example, in the case of a pump suction pipe system for a lubrication pipe line laid between the hull and suction rudder of a dredger, the suction chamber is connected to an on-board pump (which is laid below the water surface) through a rudder side suction pipe 1, a connecting rubber suction pipe 2 and an on-board suction pipe 3. In such a suction pipe system, the air accumulation is brought about in the top of an angle-like formed section of the pipe system, and therefore, an air pipe and as well an air-bleed valve chamber 5 are connected to this top part, and therefore, the top part is connected to the air chamber 16. Mingled air in the pipe is accumulated in the valve chamber 5 so that a float 6 is opened by a depressing valve 7, and therefore, flows into the air chamber 16 which is held under negative pressure. Thereby air inside the pipe is bled.

Title: Substrate treatment method and its device
Inventor: KASHIRO TAKESHI
IPC: G02F1/1333
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a substrate treatment device whose yield is improved. SOLUTION: An array substrate is held in nitrogen atmosphere for one hour at 600 deg.C after an impurity is implanted, and then the impurity is activated. After the array substrate is cooled once on a metallic plate in atmosphere whereto nitrogen is introduced, evacuation is carried out. Evacuation is stopped when a pressure is 13.3 Pa or less, the array substrate is lifted, a chamber 34 is exposed to the air again and the array substrate is unloaded. Since nitrogen creeps on the array substrate by evacuation and static electricity is not generated, a wiring is prevented from shortcircuiting due to static electricity and becoming defective.

Inventor: ARITOME SHIGEKI
IPC: H02M3/00
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a low noise switching power supply device. SOLUTION: A square-cylindrical board assembly 90 with both its end parts opened is formed by connecting four boards 91-94 to each other and housed in the housing space SP of a casing 80. Noises are emitted by a transformer 24 and noise emitting electronic components such as a power transistor 221, a bridge diode 281, etc., which are arranged in the internal space SSP1 of the board assembly 90 and transmitted to the outside of an apparatus from the board assembly via an opening.

Title: Atomizer
Inventor: HARA SHIGETAKA
IPC: F24F6/12
Filed: 1978-06-23
Abstract: PURPOSE: To lessen or remove difference in atomizing condition between products due to the dispersion of parts making up of atomization portion by making movable relatively the feeding pipe through which fogs in the atomization chamber are introduced to the outside and the atomization chamber.  
     CONSTITUTION: The liquid 8 is sent from the liquid inlet 11 to the conical cylinder 4, then made into the liquid line 15 at the opening 14 by vibration energy of the ultrasonic vibrator 1, and lastly atomized 17 by the action of the feeding air 13 from the feeding air supply opening 12. Because the feed pipe 16 through which the atomized fogs are introduced to the outside of the atomizing chamber 7a is relatively movable with the atomizing chamber 7a, optimum atomizing condition can be obtained by regulating the relative position between the pipe 16 and the chamber 7a even if the atomizing condition is out of predetermined condition due to the dispersion of parts taking part in atomization. Also, the regulation of the atomizing condition can be easily performed even by mass-productive working line.

Abstract: PURPOSE:To reduce the size of a reactive sputter etching apparatus and to suppress detrimental exhaust gas from the apparatus by stacking a plurality of substrate holders on one elctrode in a chamber, sequentially moving the holders to the other facing electrode and etching the surface of the substrate placed on each holder. CONSTITUTION:The air in a chamber 11 is substituted for reactive gas, a high frequency electric power is applied to a target electrode 14 and a confronting electrode 15, and each substrate 23 placed on a substrate holder 18 connected to the electrode 14 is etched.

IPC: G11B20/10
Filed: 1988-03-31
Abstract: PURPOSE:To always and surely perform read/write by outputting a false pulse equivalent to a sector pulse when no sector pulse is outputted. CONSTITUTION:A magnetic head 20 outputs a reproducing signal to a signal reproduction circuit 21. The circuit 21 converts the reproducing signal to a binary signal, and outputs it to a sector detection circuit 22. The circuit 22, when detecting a pattern for detecting a sector, outputs its detection signal A. A pulse generation circuit 23 generates a pulse signal P1 synchronizing with the signal A. An OR circuit 26 outputs the signal P1 as the sector pulse SP. Meanwhile, it is assumed that a state where no signal P1 is outputted is generated at the next sector after the signal P1 is outputted. Here, a counter circuit 24 starts a count operation synchronizing with the input of the signal A, and outputs a prescribed pulse after a prescribed period. A pulse generation circuit 25 outputs a false sector pulse P2 synchronizing with the pulse outputted from the circuit 24. Therefore, the circuit 26, after outputting the pulse SP, outputs the pulse P2.
