摘要:
This invention concerns a method for epitaxial growth by the use of a so-called heterogeneous reaction and includes disposing a source material in a first area of a horizontal chamber, disposing a growth substrate in a second area thereof, heating the first area thereby keeping the source material at a first temperature, heating the second area thereby keeping the growth substrate at a second temperature, lower than the first temperature, introducing a reaction gas into the chamber thereby causing the reaction gas to react with the source material and depositing the resultant reaction product on the growth substrate and consequently obtaining formation of a film by epitaxial growth.
摘要:
A cordless telephone set comprises a base unit and a handset unit connected by a radio frequency (RF) link which is established by digital burst data transmission and is synchronized by a unique word which is included in the digital burst data. The radio transmission signal is not continuous and it requires the synchronization. The unique word is detected by the unique word detecting means and is used to establish the burst data synchronization. The unite word consists of frequency channel information and fixed unite data. By using this information, the base unit and the handset unit are prevented from trying to establish a radio link at incorrect frequency when a spurious signal, not intended for the base unit and/or handset unit is erroneously received.
摘要:
The present invention relates to a method for manufacturing a semiconductor device, and more particularly to a method for forming a film used for flattening a substrate surface having unevenness in a manufacturing process of a semiconductor device, and has for its object to provide a method of manufacturing a semiconductor device for making it possible to flatten a film by processing at a lower temperature without deteriorating the film quality.The present invention is structured including a process of depositing a film composed of BPSG or PSG on a substrate surface having unevenness, a process of depositing a SiO.sub.2 film or depositing a film composed of BPSG or PSG having concentration lower than phosphorus concentration or boron concentration in the film or a SiO.sub.2 film on the film, and a process of melting and fluidizing these films so as to flatten them by applying heat treatment.
摘要:
A highly active denitrating catalyst is produced by converting the surface layer of steel material to an aluminum alloy, treating the resulting steel material with an aluminum dissolving solution to dissolve out the aluminum and to render the surface layer porous, and immersing the steel material having the porous surface layer in a solution containing a vanadium compound to cause the porous surface layer to support the vanadium compound.

Disclosed herewith is an improvement of the conventional process for the vapor growth of a thin film, such as the films of SiO.sub.2, Si.sub.3 N.sub.4, Al.sub.2 O.sub.3 and polycrystalline Si, on a plurality of wafers, such as wafers of a semiconductor, under a reduced pressure. This improved process allows the growing of a uniformly thin film on each piece of wafer. According to the present invention, the location of the wafers is changed in accordance with a specific pressure within the reaction tube.

An air-conditioning apparatus controller includes a light-emitting indicator that emits light in a plurality of colors, a main display that displays a setting screen for light-emitting indication by the light-emitting indicator, a touch panel through which an instruction related to settings displayed on the main display is input, a data processing unit of a controller that causes the main display to display the setting screen, and performs setting processing for assigning an indication color to an indication content to be provided by the light-emitting indicator, in accordance with the instruction transmitted from the touch panel, and a data storage unit that stores settings for the processing performed by the data processing unit.
摘要:
The wall-mount remote controller includes a base fixable to a wall W and a cover releasably attached to the base, having a box shape with an open rear, and covering a front surface of the base. The cover includes a bottom surface having an insertion opening therethrough. In a lower front of the base, a spring hook is disposed. The spring hook includes a support extending frontward from the front surface of the base and a hook section extending downward from an end of the support and then extending rearward. A hook protrusion is disposed on a lower surface of an extending rear portion of the hook section. The hook protrusion is engageable with the insertion opening of the cover. The hook protrusion is disengageable from the insertion opening by upward bending of the hook section caused by pressing of the hook protrusion by the tool inserted through the insertion opening.
