Title: Arcing preventive method inside electrostatic chuck and its device
Inventor: ROBAATO JIEI SUTEGAA
IPC: B23Q3/15
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent insulation destruction of heat movement fluid in an electrostatic chuck by guiding a lower side conductive layer containing a heat movement fluid distribution channel to the heat movement fluid distribution channel, so that a basic structure is formed by combining with an upper side dielectric layer containing an opening connected to it. SOLUTION: The upper surface of an electrostatic chuck 102 is covered with a dielectric layer 114. So that a cooling gas flows, through a channel 112, to the upper surface of the electrostatic chuck 102, an opening or a flow channel 202 which passes through the upper side dielectric layer 114 and a metal thin film is formed. While the thickness of the dielectric layer 114 is increased at the intermediate region of the flow channel 202, the thickness of the remaining surface region of the electrostatic chuck 102 is suppressed to a standard thickness. Thus, thanks to arcing or glow discharge between the surface of electrostatic chuck 102 and a work piece, the possibility for the cooling gas to be insulation distracted is decreased. Thus, the operational life of the electrostatic chuck is extended.

Abstract: PROBLEM TO BE SOLVED: To freely respond any channel gradient with a combination with a conventional U-shaped ditch by forming horizontal surface portions with different depths on the upper surface of the bottom of a U-shaped channel block, and a step surface portion for continuously interconnecting these. SOLUTION: A horizontal surface portion 4A with a shallow bottom, a horizontal surface portion 4B with a deep bottom, and a step surface portion 4C are formed in a U-shaped ditch 1 having a step comprising both-side wall portions 2 and a bottom wall portion 3. A projection 5 for connecting a conventional U-shaped ditch having no step is disposed on the bottom wall portion 3. When a channel with 1% gradient is built, one U-shaped ditch 1 having a 2 m long stem with 10 cm step H and four conventional U-shaped ditches with the same length are arranged and interconnected. Repeating this working pattern builds a channel with a predetermined length, and combination of number of connections forms the channel with a predetermined gradient.  Water in the channel gently flows on the horizontal surface portion 4A with the shallow bottom, drops onto the horizontal surface portion 4B with the deep bottom through the step surface portion 4C, and is accelerated adequately. This improves productivity and allows free response to any channel gradient.

Abstract: PROBLEM TO BE SOLVED: To generate electric power in accordance with a required demand load for driving a vehicle in a hybrid vehicle, in which a generator is coupled to an engine and a part of the output from the engine is transmitted to the generator and the rest to the output shaft directly. SOLUTION: An opening α of an accelerator is used as a required demand load. When this opening α of the accelerator is equal to or lower than a given value, a brake B is engaged to fix the number of revolutions of a generator. Meanwhile, the higher the required demand load (the larger the opening αof the accelerator), the larger the consumed power of a motor 4 becomes. Now, if the opening α of the accelerator is equal to or higher tan the given value, the brake B is released for increasing the energy to be generated by increasing the number of revolutions of a generator 3, in proportion to the opening αof the accelerator.
