Title: Semiconductor device and its manufacture
Inventor: WATANABE MASATO
IPC: C30B25/02
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To enable impurity activation at a low temperature in a short time, by providing a low oxygen concentration region in a silicon semiconductor substrate surface, and performing ion implantation of impurity atoms which change an electric conductivity of the surface in this region. SOLUTION: A low oxygen concentration region 3 is formed from a surface 2 of a silicon semiconductor substrate 1 toward the inside of the substrate, and ion implantation into the low-oxygen region 3 is performed, and heat treatment is performed at a temperature lower than 700 deg.C by rapid heating for 10-30 minutes. Consequently, defects formed on the occasion of the ion implantation are easy to diffuse, and the defects disappear even if the temperature of the heat treatment for electric activation of the atoms of ion-implanted impurities is low. Consequently, the implanted impurities are sufficiently activation even by low-temperature heat treatment. It becomes possible to suppress the diffusion distance of the implanted impurities, and to control the impurity concentration distribution precisely.

Title: Multilayer film surface reflector
Inventor: NAKAJIMA YUCHI
IPC: G02B5/08
Filed: 1986-12-27
Abstract: PURPOSE:To obtain a multilayer film reflector excellent in a glare shielding property, visibility, etc., by setting up the optical film thickness of one layer of dielectric films successively laminated by the prescribed number of layers to constitute a dielectric multilayer film to lambda0/2 (lambda0 is the wavelength of light to be the center of design) and setting up the optical film thickness of the other layers to lambda0/4. CONSTITUTION:The dielectric multilayer film is formed by laminating a high refractive index film layer (2H layer), a low refractive index film layer (L layer) and a high refractive index film layer (H layer) successively on the front face of a glass base 1 and a black absorbing film 9 is applied to the rear face of the same glass base 1. When the optical film thickness of at least one of the dielectric films constituting the dielectric multilayer films is set up to lambda0/2 (lambda0 is the wavelength of light to be the center of design) and the optical film thickness of the other layers is set up to lambda0/4, a reflection factor in an area with a high dark adaptive specific visibility is dropped and the glare shielding effect is improved. Since reflection factors in blue and red wavelength areas in which brightness sensitivity of human's eyes is low are increased, the visivility can be increased.

Title: Control device for fluid actuator
Inventor: KAMIBAYASHI ATSUHIRO
IPC: F15B9/09
Filed: 1990-11-14
Abstract: PURPOSE:To prevent the abnormal rising of working position/speed during speed/ position control by changing speed/position control into position/speed control when a signal/detection signal respectively subtracted by a fixed value from a detection signal for position/speed is larger than a command signal during the speed/position control. CONSTITUTION:The signal Ss of a position sensor 5 for a hydraulic cylinder 2 controlled through a servo valve 4 actuated by a signal sent from a control changing over switch 11 is established as a position control signal by determining a difference between the signal Ss and a position control signal Sr through a subtracter 6 for position and compensating the signal Ss through a compensating circuit 7. A differentiator 10 changes signal Ss into a speed detecting signal Vs, and a subtracter for speed 8 determines a difference between the speed detecting signal Vs and a speed command signal Vr, and a speed compensating circuit 9 thereby compensates the signal Vs to establish it as a speed signal, and at the same time, speed-position signal comparators 12,13 change over a control changingover switch 11. The speed detecting signal Vs is returned to the compensating circuit 7 for position. Thus the abnormal rising of working position/speed during the speed/position control and trouble caused by the abnormal rising can be prevented.

Title: Echo canceler
Inventor: HASEGAWA ATSUSHI
IPC: H04B3/23
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent sound signal delay resulted from an echo processing from being increased at an echo canceler in a packet-type transmission line. SOLUTION: The remaining echo component of the output of a substructure for echo cancel 6 is speed-converted in a buffer 4. A reception packet is speed- converted in a buffer 1. The outputs of both buffers 1 and 4 are referred to and an echo path estimation unit 2 generates a filter coefficient for estimating an echo path. An adaptive FIR filter 3 convolution-operates the filter coefficient and the output of the buffer 1 and generates a pseudo echo component. A buffer 5 makes the pseudo echo component into a packet and the subtracter 6 executes subtraction on it with a transmission packet and cancels echo. Since only a subtraction processing is executed in a transmission packet line, packet delay does not exist.

Filed: 1994-12-14
Abstract: PURPOSE: To obtain a low-noise state with high efficiency by connecting a solar battery and a capacitor together through a reactor. CONSTITUTION: The solar battery 1 and capacitor 2 are connected in parallel through the reactor 6. A load 4 and a commercial power supply system 5 are connected to an inverter 3, which converts the DC electric power across the capacitor 2 into AC power, in parallel respectively. The inequality in the figure preferably holds for the inductance L of the reactor 6, the capacity C of the capacitor 2, and the frequency (f) of the AC voltage. The reactor 6 can suppresses the influence of voltage variation of the capacitor 2, caused by a pulsating current on the input side of the inverter 3, on the solar battery 1. The voltage variation of the solar battery 1 is therefore reducible and operation at a point closer to the maximum electric power point of the solar battery 1 becomes possible. The inequality: 1/2π√(LC)<2f.

Title: Signal change-over system
Inventor: AZUMA MOTOO
IPC: H03K17/00
Filed: 1992-10-27
Abstract: PURPOSE:To eliminate a non-selection state at the time of changing a change- over signal and to eliminate the generation of a hazard signal by changing-over the signal through the state where the two signal are simultaneously selected. CONSTITUTION:When the change-over signal S inputted from an input terminal 17 is changed from L to H, the signal S is impressed on either of the OR gate 10 and A input selecting signal (c) inputted to an AND gate 1 is made to turn to H. The change-over signal S inputted from the terminal 17 passes through a delay buffer 9 and its output signal (a) is made to turn to H. Thus, through H is late impressed on the other side of the OR gate 10, the A input selecting signal (c) does not change by it. In the meantime, the signal (a) lets the B input selecting signal (b) be L through an inverter 4. Here, the delay time beta of the OR gate 3 is smaller than the sum of the delay time alpha of the buffer 9 and the delay time gamma of the inverter 4 so that the hazard signal is not generated at this time.
