Title: Deposition film forming method
Inventor: YOSHINO TOSHIHITO
IPC: H01L21/205
Filed: 1988-06-06
Abstract: PURPOSE:To prevent the deposition of a film on a light transmitting window without supplying energy from the outside by forming a film while feeding ClF3 from a second gas feeding vent. CONSTITUTION:At the same time when film forming gas is fed into a reaction vessel 101, the ON-OFF valve 122 of a gas cylinder 121 is opened, gas containing at least ClF3 filled in a gas cylinder is set at a specified gas flow rate, by a pressure reducing equipment 123 and a mass flow controller 124, and fed into a reaction vessel 101 from a gas discharging vent 152. The gas containing ClF3 forms a region where the gas containing at least ClF3 flows, between a region where the film forming gas supplied from the gas feeding vent 151 and a light transmitting window 103. The gas prevents the deposition of precursor turning to the origin of deposition film on the light transmitting window 103. Further the gas reacts with the precursor, turns it into silane compound gas in a reactive state, discharge it, and returns reaction product on the light transmitting window 103 to vapor phase. Thereby, the attaching of the reaction product to the light transmitting window 103 can be prevented.

Abstract: PROBLEM TO BE SOLVED: To make a product have metallic gloss, have plane parts and uneven parts alternately, and have an extremely beautiful appearance. SOLUTION: A backing 5 is molded with the use of an injection molding method, etc. In this process, plane parts 6 and uneven parts 7 are formed. Next, by a known spattering method, a metal layer 8 is formed on the surface of the backing 5. After that, a clear coating material is applied to form a clear film layer 9 to cover the metal layer 8. Since the metal layer 8 is very thin and fine gap can exist among metal particles constituting the layer 8, the clear coating material enters the gaps to be bonded to the backing 5. Since the clear film layer 9 is composed of a resin as the base material 5 is, the bond strength between the backing 5 and the clear film layer 9 is very large. Besides, the metal layer 8 of the plane part 6 is mirror-shaped.  The metal layer 8 of the uneven part 7 is formed to be finely uneven, giving different appearances by view angles due to the irregular reflection of light.

Filed: 1987-06-04
Abstract: PURPOSE:To attain wide recording power margin without deteriorating an optical disk by widening a recording/reproduction beam at recording and narrowering the beam at reproduction. CONSTITUTION:A recording/reproduction collimator lens is moved in the optical axis direction at recording to apply defocusing and an elliptic erasure beam 18 is radiated to erase a recording bit 17 and the recording beam 19 modulated by the signal is used for recording. At reproduction, said collimator lens is focused at the reproduction and the stopped reproduction beam 20 is used to sense the difference in reflectance.

Abstract: PURPOSE:To realize high-speed logical fault simulation which utilizes the parallel arithmetic mechanism such as a vector computer even for a synchronous sequential circuit and to greatly decrease the man-hours and shorten the processing time at the time of logical verification and test data generation. CONSTITUTION:This logical arithmetic method finds an output data string, obtained when plural input patterns are supplied in order to a storage element whose output values depend upon the sequence of input values, by the parallel arithmetic mechanism. It is decided whether or not the output value of the storage element for each of the patterns in time series is a held pattern depending upon a last pattern to find a 1st data string consisting of flags indicating whether or not each pattern is the held pattern and a 2nd data string consisting of a predetermined value for the held pattern or the output values of the storage element for an unheld pattern. Then the 1st and 2nd data strings are processed in parallel by using the parallel arithmetic mechanism to obtain output data strings of the storage element in parallel.
