Title: Circuit and method for automatic gain control
Inventor: KERII SHII GUROOBAA
IPC: G11B20/10
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To configurate an automatic gain control circuit such that fast and exact output gain control signals can be generated. SOLUTION: A full-wave rectifier 70 receives a continuous time readout signal and generates a rectified current readout signal to be supplied to an adder circuit 74, which generates an offset signal which is obtained as a difference between the rectified current raedout signal and a threshold signal. The offset signal is supplied to a multiplier circuit 82, which multiplies the offset signal by the first or second gain signal to generate an error signal. A multiplexer 76 determines which one of the first or second gain signals is to be supplied to the multiplier 82. The multiplexer 76 is controlled by the comparator 72 which generates a signal indicating whether the rectified readout current is higher or lower than the threshold signal. The low-pass filter 86 receives error signals to generate output gain signals.

Title: Thin film solar cell
Inventor: IMAIZUMI KATSUMI
IPC: H01L31/04
Filed: 1984-06-26
Abstract: PURPOSE:To contrive further improvement of efficiency by providing light absorbing or light reflecting bands for reducing light conduction effect of a photo-electric transfer thin film layer in the spaces among electrode layers on a light acceptance side. CONSTITUTION:Light absorbing bands 8 are arranged in the spaces among ITO electrodes 7 on a glass substrate 4 for reducing the quantity of incident light. These light absorbing bands 8 are formed, for example, by screen printing and calcination of paste-state black glass. Thus the quantity of incident light among the thin film solar cell elements is reduced and the light conduction effect of the amorphous Si layers of those parts is decreased, thereby reducing (thicknessX rate of electric conduction sigmat) of a semiconductor layer. If sigmat is reduced, the ratio of a width of the element W to a distance l for the same allowable leakage current I, W/l becomes larger and the allowable minimum value of the element intervals can be further reduced. A reflection band is available instead of the light absorbing band.

Filed: 1981-08-26
Abstract: PURPOSE:To obtain a convergent beam with deep focal depth by fitting an acoustic lens having a curved surface to a surface of a linear array oscillator, or by phase-driving the linear array oscillator. CONSTITUTION:Impulses having numbers of successive wave surfaces are generated in such a way that focuses distributed successively on a center axis which crosses the array direction of a linear array oscillator 31 at right angles and is positioned in the center of the oscillator are multiplied through an acoustic lens 23 respectively, thus converging an acoustic wave beam. In another way, each oscillator of the linear array oscillator 31 is phase-driven with adequate delay time without using said acoustic lens 32, thereby generating impulsive wave surfaces.

Abstract: PURPOSE: To form a high concentration additive region of fixed dimensions on a base plate, by operating mesa-etching with the prearranged region for adding impurities set as the top surface, diffusing impurities with the mesa side surfaces covered with a protective film.  
     CONSTITUTION: SiO 2  22 and positive photoresist 23 are laminated on p-type Si base plate 21. When this is exposed and developed by using mask 24, resist film 23 of size E, smaller than the size D of the mask pattern is formed. When this is etched after exposure to ion irradiation, film 22 of size F<E is obtained. Next, when the Si base plate is etched, a mesa summit of size G<F is formed. Resist 23 and SiO 2  22 are removed, and the base plate is cleaned. After this, by selectively coating resist 26 and injecting B ions, a p + -layer is formed on the mesa top. By this method, the impurity-added region can be made smaller than the size of the mask pattern, and thereby a high-density device can be obtained.
