Title: Semiconductor memory
Inventor: ARIMOTO KAZUTAMI
IPC: G11C11/404
Filed: 1985-06-06
Abstract: PURPOSE:To obtain a semiconductor memory capable of writing bit line potential to a memory capacitor as it is by forming a transfer gate between a bit line and the memory capacitor by a P channel transistor and an N channel transistor. CONSTITUTION:When a cell is selected, signals at 'H' and 'L' are each applied to word lines 3 and 6, and transistors 2 and 5 are turned ON. A memory capaci tor 4 and a bit line 1 are brought to the same potential by the transistor 5 regarding reading and writing at 'H', and the transistor 2 conducts the same operation regarding reading and writing at 'L'. The quantity of information is not lost by the threshold voltage of the transistors 2 and 5 even on data at both 'H' and 'L'. According to the constitution, the pressure rise of the word lines 3 and 6 and the like are unnecessitated, thus also shortening the time for the pressure rise, then resulting in speed-up. Consequently, data can be written and read without reducing the quantity of information, thus eliminat ing the need for the pressure rise of the word lines.

Title: Magnetic recording and reproducing device
Inventor: YAMAMOTO YOSHIHITO
IPC: G11B5/03
Filed: 1985-06-06
Abstract: PURPOSE:To attain no adjustment of a bias current in a recording mode by providing a means detecting automatically a recording bias current and a means controlling the bias current in accordance with the output. CONSTITUTION:In a reproducing mode, the reproduction output of an audio head 4 is inputted to a reproduction equalizer amplifier 2 without being affected by a bias trap 7, while in a recording mode a recording current where the output of a recording amplifier 1 and that of a bias generating circuit 3b are superimposed is flowed through the head 4 and a transistor 6. A signal in an audio frequency band is cut by the trap 7, and only a bias signal is detected by a diode 8 and fed back to the generating circuit 3b. Accordingly, since the bias current value is detected and controlled, the bias current can be automatically controlled even when the impedance of the head 4 fluctuates. As a result a cost price is cut down, and production efficiency can be improved.

Abstract: PURPOSE:To make it possible to certainly detect the size of a flaw and the depth thereof on the surface of a material, by using a solution containing a dye showing a red color under white light and showing red - yellow fluorescence under ultraviolet rays and increasing in the density of a visible color while reducing in fluorescence at definite concn. or more. CONSTITUTION:A dye showing a red color under white light and red - yellow fluorescence under ultraviolet rays and increasing the red color density as the concn. thereof is increased and gradually reducing fluorescence at definite concn. or more (mentioned as a density extinction phenomenon), for example, Oil Scarlet 308 (manufactured by Orient Co.) is dissolved in a penetrant in an amount of 10-30pts.wt. with respect to 100pts.wt. said penetrant. The dye may be either water soluble or oil soluble and a surfactant may be added to enhance penetratability. The surface of a specimen is coated with this penetrant 2 and, after the excessive liquid is wiped off, coated with a developer 3 comprising an inorg. white fine powder. When a defect part 1 is shallow, the changes in the density of visible light and fluorescence are small or are not appeared regardless of the size thereof. At a part where a flaw is deep or the interior of the flaw is large even if a surface opening is small, the density of the visible light color is increased with the elapse of time while the intensity of fluorescence is contrarily reduced and the degrees thereof are different according to the depth and the size of the flaw.

Title: Capstan servo circuit
Inventor: NAKAMURA KAZUHIKO
IPC: H02P29/00
Filed: 1988-05-20
Abstract: PURPOSE:To surely perform the servo control by sufficiently approximating the rotative speed of a capstan motor to a target speed at the time of start and absorbing and correcting the variance of the rotative speed based on pressing of a pinch roll before the start of phase control. CONSTITUTION:When a capstan motor 2 is started, the supply of a phase error signal is inhibited by a start control switch means 23, and the rotative speed of the capstan motor 2 is quickly and surely led to the target speed based on the corrcetion bias of a correction signal, which is synthesized with a speed error signal by addition, independently of the variance of motor characteristic. Though the pinch roll is pressed to a capstan shaft simultaneously with the start of recording or reproducing to reduce the rotative speed of the capstan motor, the variance in speed due to pressing of the pinch roll is absorbed and corrected by the speed control based on the speed error signal and the correction signal before the start of phase control because the supply of the phase error signal is inhibited. Thus, the servo control is surely performed.

Filed: 1979-09-26
Abstract: PURPOSE:To obtain a hydrogen-storing alloy having excellent practicability by alloying Ti, Fe, and Hf in a specific ratio. CONSTITUTION:A ternary alloy of the formula Ti1-xHfxFey (where x and y are in the relationships 0<x<=0.2 and 0.8<=y<=1.15, most preferably in the relationships 0.01<=x<=0.05 and 0.95<=y<=1.05) is melted to form the ingot of a homogeneous phase alloy and then the ingot is pulverized into grains of a size of approx. several mm.. Then, the grains are put in a container and then the container is  evacuated by a vacuum pump, filled with hydrogen gas at a pressure of approx. 10 atm or more, and then subject said alloy grains present to a hydrogenation treatment at room temperature so as to cause hydrogen to be absorbed and stored in the alloy. When releasing the hydrogen from the alloy, the container is opened at room temperature and atmospheric pressure, whereupon the hydrogenated alloy can easily release hydrogen reversibly. Because the conditions for treatment thereof such as temperature, pressure, and degassing time, are more eased than the conventional hydrogen-storing alloys, said alloy is excellent in practicability.
