Title: Laser diode drive circuit
Inventor: SATO MASAHIKO
IPC: G11B7/125
Filed: 1988-09-30
Abstract: PURPOSE:To make APC operations executable even in the recording mode so as to prevent occurrence of insufficiency in power at the time of mode switching by driving a laser diode with a constant current when the mode is switched to the recording mode and switching the drive of the diode to a recording power control circuit side after a feedback signal to the control circuit becomes equal to the set voltage of the circuit. CONSTITUTION:The laser diode drive circuit is provided with a constant-current drive circuit 30, recording power control circuit 20, and recording power set circuit 40 and a laser diode LD is driven by means of the circuit 30 when the mode is switched to the recording mode. The drive of the diode LD is switched to the circuit 20 side after a feedback signal to the circuit becomes equal to the set voltage of the circuit 20. Therefore, APC operations (by which the magnitude of a drive current 11 is controlled so that the emitting power of the diode LD can become fixed power corresponding to a reading power setting voltage Vr1) can be started when the feedback signal to the circuit 20 rises. Thus the APC operations can be performed even in the recording mode and occurrence of insufficiency in power at the mode switching time can be prevented.

Title: Semiconductor integrated circuit device
Inventor: MINE HIROTOSHI
IPC: H01L21/82
Filed: 1989-09-25
Abstract: PURPOSE:To maintain acceleration of circuit operation even with a large-sized macro mounted by a method wherein a large-sized macro and middle- and small-sized macros are mixed on a master chip while the large-sized macro is provided with a wiring extending over the macro with a thick insulation film. CONSTITUTION:A center part of a semiconductor integrated circuit device 1 is an inner cell region 5, where a large-sized macro 4 is provided in addition to middle- and small-sized macros 6. On the large-sized macro 4 part, a inner macro wiring 8 is formed via an insulation film 10, and a signal line wiring 7 is formed via a thick insulation film 9 thereon. Thus the wiring 7 is formed via the thick insulation film 9, so that no large capacitance is parasitic between the semiconductor element and this wiring even if wiring length is long.

Filed: 1987-09-30
Abstract: PURPOSE:To execute the measurement with high accuracy, at high speed and with high efficiency by changing automatically a measuring condition of a measuring instrument in at least one prescribed point in a sweep section of once. CONSTITUTION:An operator of a sweep measuring instrument moves a marker to a suitable position from a display, etc., of a display 10, and moves a second marker for designating a sweep section started from a frequency designated by the marker. These data are stored in a RAM 4. Subsequently, a sub- microprocessor (CPUB) 5 reads out these data, executes setting of a measuring part 7 required for a sweep, reads out a measuring procedure in a ROM 6 by a trigger of a main microprocessor (CPUA) 1, and sweeps it repeatedly. Next, the CPUB 5 stores a measured data in the RAM 4 together with a measurement end tag, and stops after having stored the last measured data. Thereafter, the CPUA 1 detects the end of the sweep by the number of end tags, tests a sweep repeating flag of a RAM 3 and determines whether the repetition of the sweep exists or not. In such a way, the measurement can be executed with high accuracy, at high speed and high efficiency.

Abstract: PURPOSE:To obtain an agricultural and horticultural germicide containing a mixture of a 1,2,4-triazole derivative with at least one of basic copper chloride, basic copper sulfate, cupric hydroxide, basic copper phosphate sulfate and anhydrous copper sulfate as an active ingredient and capable of exhibiting high effects in a small amount of chemical. CONSTITUTION:An agricultural and horticultural germicide containing a compound expressed by the formula (X is up to 2 halogens or lower alkyl; Y is up to 2 halogens) and a copper germicide such as basic copper chloride at 1:(1-500) weight ratio. Two ingredients of the aforementioned germicide cooperatively and mutually act to exhibit synergistic controlling effects and show high control effects on, e.g. cercospora leaf spot of sugar beet, anthracnose, downy mildew and powdery mildew of grape, powdery mildew, downy mildew and scab of cucumbers, late blight of tomato, etc. Since a smaller amount than that in individual use is sufficient, occurrence of phytotoxicity due to single use of the copper germicide can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To obtain an alloy in which the refining of the cast structure can be attained while the formation of Fe crystallized protects is prevented and capable of improving workability at the time of hot rolling by incorporating specified amounts of Fe, P, Zn and Si into Cu. SOLUTION: This alloy is an alloy composed of, by weight, 1.5 to 2.5% Fe, 0.001 to 0.1% P, 0.01 to 1.0% Zn, 10 to 1000 ppm Si, and the balance Cu with inevitable impurities, where the most preferable amt. of Si to be added is 50 to 400 ppm. Fe is added for improving its strength and heat resistance, but, in the case of >=2.5%, coarse Fe crystallized productes are formed at the time of casting, and, in the case they remain in the product, bending and cracking are caused, and the defect in plating occurs. Si is added for refining the cast structure, but, in the case of <10 ppm, it is not sufficient for obtaining the effect, and, in the case of >=1,000 ppm, a saturating tendency is shown in the refining effect of the cast structure, and, moreover, the reduction of the electric conductivity is caused.
