Inventor: TERAOKA ARIDONO
IPC: H01L21/322
Filed: 1990-04-27
Abstract: PURPOSE:To further lower a heavy metal density at the surface of a semiconductor surface by enhancing generation efficiency of a silicide of heavy metal through optical decomposition of silicon oxide. CONSTITUTION:Oxygen is in the excessively saturated solid soluble condition, and an Si substrate 4 including heavy metals is subjected to heat processing within a vacuum chamber 2 which is kept under the ultrahigh-vacuum condition by a vacuum evacuation system 5 by making use of a heater provided in a substrate maintaining device 1, in order to precipitate SiO2. This reaction simultaneously produces interlattice Si atoms. In parallel with the heat processing, the Si substrate 4 is irradiated with SR emitted from the SR(synchrotron radiation) light source 7 through an SR spectroscope 6 for selective optical decomposition. Thereby, balance of SiO2 precipitation reaction is deviated toward the interlattice Si atom generating direction and production of silicide of heavy metal is accelerated. The heavy metal atoms are accelerated by Si atoms between the gratings generated only with the heat processing within the substrate where the light does not reach and an ordinary intrinsic gettering is executed.

Title: Power failure logging method
Inventor: FUTAMI HIROAKI
IPC: G06F1/28
Filed: 1990-05-02
Abstract: PURPOSE:To record a phenomenon of the lowering of an input voltage and its occurrence time by holding the detection results of the detection means for these phenomenon and time respectively and then writing these held contents into a readable storage means at the later application of a power supple. CONSTITUTION:When the input voltage level is lowered, a power source originates an AC FAIL signal and this signal is detected by a detection mans 32 which holds its state even at power supply OFF. This detection result is held and then a lowering phenomenon of the input voltage level is held. Furthermore a time counter means 26 which holds its state even at power supply OFF is stopped by the AC FAIL signal. Thus the time when the input voltage level is lowered is held. Then the time counting stop time held by the means 26 is read out as long as the level reduction phenomenon detection state is held when the power supply of a device is applied again. Then this phenomenon and the time counting stop time is stored is a storage means 22 which holds its state even after the power supply is turned off. Thus the files can be obtained for the input voltage lowering phenomenon and its occurrence time.

Title: Picture packet multiplexer
Inventor: SUZUKI TAKAO
IPC: H04N19/37
Filed: 1990-05-02
Abstract: PURPOSE:To prevent missing of picture information at receiver side and deterioration of a picture by comparing a moving average of input speeds of input signals to a buffer means with 1st and 2nd threshold levels respectively, giving priority to a signal of a terminal equipment and processing the signal into a packet when the moving average exceeds the 1st threshold level. CONSTITUTION:Moving average calculation sections 121-12n apply weight average calculation to a time series data of a picture coded signal by a weight function to obtain a moving average Y. Then threshold levels A1, A2 of the moving average Y are provided to set a normal area, a high load area and an overload area. A transmission assignment processing section 10 applies packet processing to a signal at a terminal equipment when the moving average Y enters the overload area with priority. When the moving average Y enters the high load area, the packet processing is stopped. When the moving average is a history for processing period, it represents prediction that the tendency at a current point of time will continue for a while. Thus, the capacity excess of an exchange network is prevented in advance.

Title: Control device of supercharge pressure in engine with supercharger
Inventor: MAMIYA KIYOTAKA
IPC: F02B33/44
Filed: 1984-06-04
Abstract: PURPOSE:To improve stability and a response characteristic in feedback control of the supercharge pressure always by a control constant of accurate value, by changing at least one of the proportional gain and the differential gain in accordance with a quantity of change in an actual supercharge pressure from the target supercharge pressure as the control constant of the feedback control of the supercharge pressure. CONSTITUTION:A target supercharge pressure determining means 30 determines the target supercharge pressure by an operative condition detecting means 25, and a supercharge pressure control means 31 controls an actual supercharge pressure by a supercharge detecting means 21 so as to be brought in a close value to the target supercharge pressure. Further a control constant changing means 32 uses a proportional gain PG1 and a differential gain DG1 of predetermined value as the control constant under a steady condition that a difference ¦Pa-PD¦ between the actual supercharge pressure Pa and the target supercharge pressure PD is within a predetermined value. When control is in a transient condition that the difference ¦Pa-PD¦ is in the predetermined value or more, the control constant is changed by using a proportional gain PG2 smaller than the above described proportional gain PG1 and a differential gain DG2 larger than the above described differential gain DG1 as the control constant.

Title: Patterning process
Inventor: SETO KAZUO
IPC: B05D5/06
Filed: 1979-09-08
Abstract: PURPOSE: To utilize a resin in the coating material for patterning, to coat with a high molecular layer, and to enhance durability by a method wherein a water- soluble high-molecules-containing emulsion is coated on the coating surface of a substrate and is dried at a temperature lower than the lowest minimum-film-forming temperature.  
     CONSTITUTION: In decorating the surface of an inorganic material plate used for buildings such as asbestos cement plate or calcium silicate plate, an emulsion coating material including a water-soluble high molecular material such as polyacrylic acid is first coated on the surface being decorated of a substrate, and is dried at a temperature lower than the minimum-film-forming temperature, the lowest in the coated emulsion. In such a condition, the emulsion coating material forms no film, resin content in the material precipitates in pattern around impurity nuclei as drying proceeds, and water-soluble high molecular material forms a film to cover the surface to be decorated. Said process thus facilitates the formation of a three-dimensional pattern and increases durability and water-proofness.
