Abstract: PURPOSE:To select automatic sound volume level adjustment (ALC) operation together with volume operation by providing the 1st gain adjustment means adjusting the gain of a differential circuit through the adjustment of a variable resistor and the 2nd gain adjustment means adjusting the gain of the differential circuit in response to the output amplitude of the amplifier means. CONSTITUTION:A control voltage Vc1 is obtained in the 1st gain adjustment means(variable voltage setting circuit 12) by dividing a reference voltage Vref by a variable resistor 123 and the control voltage Vc1 is fed to differential circuits 23, 24. As a result, a desired gain G1 is set by the adjustment or the variable resistor 123 to the amplifier means and an output level in response to the operation of the variable resistor 123 is obtained. Furthermore, the output amplitude of the amplifier means is detected in the 2nd gain adjustment means(automatic gain adjustment circuit 13) and a gain G2 by a control voltage Vc2 in response to the output amplitude is set to the differential circuits 23, 24. As a result, the output level is suppressed with a large output amplitude and the suppression of the output level is relaxed with a small output amplitude to obtain the level output adjusted in response to the amplitude of an output signal Vo.

Abstract: PURPOSE:To permit quick production of a photomask with high accuracy by forming a thin of diamond, diamond-like carbon or amorphous carbon on the surface of a substrate and projecting a high-energy beam to the specific points thereof, thereby drawing a prescribed pattern. CONSTITUTION:The substrater 1 is a flat plate made of quartz glass having high light transmittance and the flatness thereof is 1mum.

The condensing point of the beam is adjusted to the point at which the beam does not arrive at the substrate 1 itself. The beam having the heat capacity sufficient to heat the projected part of the thin film 2 to about 1,500 deg.C is used. Since the beam can be condensed to 1mumphi in order to enhance the accuracy, the graphitized part 3 of a min. line width 1mum, i.e., the prescribed pattern of the low light transmittance is automatically drawn on the thin film 2. The quick production of the photomask having high accuracy is thereby permitted.

Abstract: PURPOSE: To enable a compound semiconductor to grow epitaxially well so as to manufacture a semiconductor element of high quality by a method where a silicon substrate is previously irradiated with neutron before a III-V compound semiconductor is formed on the silicon substrate. CONSTITUTION: A III-V compound semiconductor thin film which contains P as V element is formed on a silicon substrate for manufacturing a semiconductor element. In this case, the silicon substrate is previously irradiated with neutron before the III-V compound semiconductor thin film is formed on the silicon substrate. For instance, after the silicon substrate is irradiated with neutron, an InP layer is epitaxially grown on the silicon substrate, and then an InGaAsP layer or the like is laminated thereon for the manufacture of a double- heterojunction laser. By this setup, P atom is configured at the position of an Si lattice on the silicon substrate by irradiation with neutron without deteriorating the silicon substrate in crystallinity.  Therefore, III atoms 15 are selectively attached to serve as a first layer of a III-V compound semiconductor layer and then successively laminated in conformity to crystal structure.

Abstract: PROBLEM TO BE SOLVED: To detect a malfunction range owing to interference with an external signal in the self refreshing operation of a storage element in short time by providing a detection means, a generation means generating the external signal to the storage element and a comparison means. SOLUTION: The detection means 21 detects the generation timing(GT) of a refreshing operation signal (R signal) corresponding to the change point of power current changing when the storage element 20 having a self refreshing operation executes the refreshing operation. The generation means 23 generates the external signal to the element 20 in a period which is considerably shorter than the generation period of the R signal. A control means 22 generates the external signal at timing when prescribed time elapses from detected GT and stops generation after prescribed time. The comparison means 24 compares holding data of the element 20 with comparison data while the external signal is supplied to the element 20 from the generation means 23 and recognizes the time range where a result is not matched as the malfunction range of the element 20.
