Title: Manufacture of silicon substrate for integrated circuit
Inventor: KANAMORI KATSU
IPC: H01L21/265
Filed: 1985-12-04
Abstract: PURPOSE:To form a SIMOX of low defect density and high quality by repeating the steps of raising an accelerating voltage of implanting oxygen ions, cooling a substrate, and annealing it whenever the implanting amount arrives at a predetermined level. CONSTITUTION:Oxygen ions are implanted at 100kV or higher of accelerating voltage to a single crystal silicon substrate. The substrate is cooled at this time, and temperature during implanting is maintained at approx. 100 deg.K. When the implanting amount becomes 1X10<15>cm<-2> or more, the substrate is removed from an ion implanting unit, and annealed. The ion implanting and the annealing steps are repeated, and the total implanting amount is set to 5X10<17>cm<-2>. Thereafter, after the substrate surface is cleaned, an epitaxial growth is executed. The defect density of the thus manufactured substrate is 1X10<4>cm<-3> or less, and the improper rate due to the leakage of a device formed on the epitaxial layer is reduced 50% or more than a conventional method.

Filed: 1989-10-19
Abstract: PURPOSE:To maintain the accuracy of envelope detection even at the time of a long-time mode by switching the peak value holding time constant of the peak value holding circuit of a peak holding circuit to a large time constant at the time of the long-time mode. CONSTITUTION:A capacitor C2 for peak holding is connected in parallel with a capacitor C1 for peak holding and a switch 10 is controlled by a long-time mode switching signal to turn the connection of the capacitor C2 on and off. The switch 10 grounds the one terminal of the capacitor C2 and connects the same in parallel to the capacitor C1 when the switching signal to set the long- time mode in which the rotating speed of the rotary heads 2a, 2b of a magnetic recording and reproducing device is halved is outputted. The value of the capacitor for peak holding is thereby increased to approximately double the peak value holding time constant. Thus, the operation of the peak holding circuit is normally executed and the same accuracy of the envelope detection as the accuracy at the time of a standard mode is maintained.

Title: Treating agent for heavy metal-containing waste and stabilizing treatment of heavy metal-containing waste
Inventor: IKEDA KOICHI
IPC: C09K17/32
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To stabilize the elution of heavy metal ions to a standard value or lower, to keep the stabilization effect on heavy metal ions and to completely prevent secondary pollution by incorporating a pozzolan active material which is solid at normal temp., and an inclusion compd. and polysaccharides. SOLUTION: The pozzolan active material used as the essential component of the treating agent is hardened by the reaction with water and calcium oxide and the like. The treating agent contains not only a pozzolan active material but an inclusion compd. and/or polysaccharides. The inclusion compd. as the host traps heavy metal compds. or heavy metal ions as guest compds. by hydrogen bonds, van der Waals force and the like and stabilizes them as host-guest compds. The polysaccharides show water absorption-swelling behavior in the presence of water or change into a paste. These changes cause a separating effect on free water from heavy metal compds. to seal the heavy metal compds., and this effect and sealing contributes to stabilization of a waste containing heavy metals.

Title: Burner of powder particle fuel
Inventor: KANEDA HIROSHI
IPC: F23C99/00
Filed: 1988-10-31
Abstract: PURPOSE:To form a large recirculation region in the neighborhood of a burner to disperse pulverized coal in a pulverized coal concentrated flow so as to prevent primary air and the pulverized coal from turning by providing a concentrator of a powder particle-like fuel, a dispersion plate for dispersing the fuel and a turn prevention plate of the fuel in a fuel supply tube and a burner. CONSTITUTION:A pulverized coal flow carried by primary air is divided into a pulverized coal diluted flow 7 and a pulverized coal concentrated flow 8. The pulverized coal concentrated flow 8 is allowed to flow toward a burner outlet while turning in a fail pipe 21. As the result, because a porous pulverized coal dispersion plate 22 is set between a pulverized coal concentrator 6 and the burner outlet, the pulverized coal is removed from a wall surface to disperse in the fail pipe 21. Further, a turn speed constituent is eliminated by a turn flow prevention plate 23. Accordingly, since fuels such as pulverized coal and oil of fire-resistance of small volatile component can be burned by sufficiently lengthening furnace retention time, unburnt components are decreased to burn completely.

Abstract: PURPOSE:To miniaturize a camera, to improve the assembling property thereof and to reduce the number of parts by obtaining such constitution that a one-dimensional light emission means is disposed so that it is opposed to a film at a position where the film is wound to a photographing roller and desired data is imprinted while the film is fed. CONSTITUTION:The photographing roller 56, a photographing lens 46 and the one- dimensional light emitting means 86 which is oppositely arranged within the range of the photographing lens 56 with which the film is closely brought into contact and which imprints the data on the film in the course of traveling are provided. Besides, a keyboard 102 which inputs the data which is imprinted and a control means 88 which selectively makes the respective picture element of the emitting means 86 emit light according to the inputted data synchronously with the feeding of the film. In such a case, the data inputted by the keyboard 102 is stored in the control means 88 and the respective picture elements of the emitting means 86 are selectively made to flicker by the control means 88 according to the data. Since the film travels at a fixed speed during the flickering action, the prescribed data is imprinted on the film. Thus, the traveling distance of the film can be made short and the camera is miniaturized. Besides, the assemblage thereof is facilitated and the number of parts is reduced.

Title: Acoustic echo cancellor
Inventor: YOSHIDA HIDEYUKI
IPC: H03H21/00
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To satisfactorily hold the sound quality of a cell even if external environment and the like fluctuate by controlling attenuation quantity in an attenuation part based on echo cancel quantity inputted from an echo detection part. SOLUTION: An A/D converter 2 converts an input analog sound signal from a microphone 1 into digital '←'. An operation block 3 is provided with an adaptive FIR filter F generating a pseudo echo signal from a reception signal and subtracts a pseudo sound signal from input sound. An attenuator device 4 attenuates a transmission sound signal and a CODEC device 5 compresses the sound signal. A D/A converter 8 converts a digital sound signal into analog '←', and a speaker 9 outputs sound 10. An echo detection part 11 detects echo cancel quantity in the operation block 3. A control part 12 controls the attenuation quantity of the attenuator device 4 so that it conflicts with the size relation of echo cancel quantity which the echo detection part 11 detects. Thus, satisfactory cell sound quality can be obtained with such constitution.
