Patent JP-S59133736-A (JP)
Title: Signal input and output device
Inventor: TERAI KAZUHISA
IPC: H03K17/16
Filed: 1983-01-20
Abstract: PURPOSE:To switch effectively signals by reducing the counter electromotive force generated at an inductive load by the inversion of polarity of the DC component of a DC/AC current and at the same time preventing the propagation of the counter electromotive force to a current switching point by a current switching contact. CONSTITUTION:A diode bridge circuit BR1 is used to protect a circuit from the counter electromotive force generated at an inductive load within a signal input/ output device in case the DC and AC signals of a telephone circuit LN are connected. Then the circuit BR1 is put between a relay contact K1 and a coil L1, and the variations of positive/negative polarities of a circuit control signal are transmitted to the coil L1. As a result, the generated counter electromotive force is considerably reduced. In such a way, the generation of noise is prevented. Then the circuit control signal is intermitted with intermission of the contact K1. Therefore, the current is absorbed by the circuit BR1 although the counter electromotive force is generated at the coil L1, the generation of noises is suppressed.

Title: Manufacture of oxide magnetic thin film
Inventor: FUJII SHIGEO
IPC: G11B5/851
Filed: 1984-01-19
Abstract: PURPOSE:To form a gamma-Fe2O3 magnetic thin film having excellent magnetic characteristics by sputtering an Fe3O4 thin film contg. oxygen in exact quantities. CONSTITUTION:When sputtering is carried out in a neutral atmosphere by using Fe3O4 target, alpha-Fe2O3 having a high oxygen content as compared with Fe3O4 is incorporated into the target to supply the deficiency of oxygen in the formed Fe3O4 thin film. alpha-Fe3O3 is stable even at ordinary temp., and can be present as a stable phase when incorporated into the Fe3O4. Accordingly, the target can be easily manufactured. Nevertheless, since alpha-Fe2O3 is weakly ferromagnetic, the content is regulated to <=10%, preferably to <= several percent. When the sputtering is carried out by using the Fe3O4 target contg. alpha-Fe2O3, an oxygen deficiency is not caused. Consequently, the conversion into gamma-Fe2O3 proceeds easily, and the magnetic characteristics are improved.

Abstract: PURPOSE:To output an inclination abnormality signal when the value of inclination is above a specified value by detecting coordinates of plural edge points of an original and calculating inclination of at lest one point. CONSTITUTION:An instruction to detect the size of original is transmitted from an MPU1 to an input device control section 2 and an original size detecting section 3 detects coordinate values of four points. Cases in which any two points of A-D are superposed having the same coordinate are extracted, and a case in which the original is set nearly parallel to X-axis and Y-axis is considered. When coordinates of all of four points are different, values of inclination theta1, theta2 are calculated from B-A, B-C making B coordinate a representative point. This is compared with the allowable limit value theta0. When the value is smaller than theta0, the inclination is judged as negligible, and when larger than theta0, judged as original set error, and original set error information is reported to the MPU1.

Title: Method for activating hydrogen storage alloy
Inventor: SHIMIZU TAKASUMI
IPC: C01B3/00
Filed: 1986-01-17
Abstract: PURPOSE:To easily reactive the H2 occluding and discharging capacity by bringing the titled hydrogen storage alloy into contact with at least one kind of gas among H2, CO2, CH4, N2, and an inert gas each contg. CO to inactivate the surface, and by preventing the reaction with oxygen even when the alloy is taken out into the air. CONSTITUTION:The surface of the hydrogen storage alloy is activated by allowing the alloy to occlude and discharge hydrogen, and the alloy is used in the form of powder to accelerate the hydrogenation reaction and discharge reaction. Since the powdery activated hydrogen storage alloy is easily oxidized and burnt by the oxygen in the air when the alloy is taken out into the atmosphere, the alloy is brought into contact with at least one kind of gaseous mixture among H2, CO2, CH4, N2, and an inert gas each contg. CO to prevent the oxidation. Consequently, the surface of the powdery hydrogen storage alloy is positioned by CO and inactivated, and the alloy is not oxidized and contaminated even when placed in the air. Besides, when the alloy is placed in a hydrogen storage vessel and the vessel is evacuated, the alloy is easily activated, and the hydrogen storing and discharging capacity is restored.

Abstract: PURPOSE:To measure the pressure distribution at the grip section of a hand of a robot economically by connecting a power source to a number of pressure detecting sections arranged in a matrix only when detection is done, to perform an arithmetic processing of outputs of the pressure detecting sections for temperature compensation simultaneously. CONSTITUTION:A number of pressure detecting sections 1 of a semiconductor strain gauge are combined with thermistor temperature detection elements 18 set by set, the outputs thereof inputted into an axis-of-ordinate address 19 and then, into an axis-of- abscissa address 20. Then, after amplified with an amplification circuit 16, they are inputted into a microcomputer section 17 to perform an arithmetic processing on a pressure signal for temperature compensation and results are outputted from an output circuit 37. At this point, according to a command from a CPU33, detection is performed sequentially with many pressure detecting sections 1 and the results are swept to compute the pressure distribution as a whole while a power source 44 is connected only during the detection by the axis-of-ordinate address of the pressure detecting section. This eliminate the need for preparing computers for the pressure detecting sections one per each while saving power for pressure detection thereby enabling the measurement of the pressure distribution economically.

Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To convert a voltage level between circuits constituted by different technologies by transmitting a 2nd voltage level from a means which converts a 1st voltage level to a necessary circuit which is needed for operation. SOLUTION: The input signal from a circuit 10 reaches a line 14 and is received by the drain electrode of an N type device 32, which has a power source of 2.5 V connected to its gate electrode. When the receive signal is at low level, a series transistor 32 passes it to the input of a receiver, which processes and outputs the signal to a line 16. When the receive signal is at high level, on the other hand, the device 32 limits the passage of the input signal to the value obtained by subtracting the threshold value of the device 32 from the gate voltage. This limit voltage is applied to the input of the receiver 38 and put in the level range needed for the CMOS technology implemented in the circuit 12. Then one input terminal of a differential receiver 34 is connected to the source electrode of the device 32 and the other is connected to a set reference voltage.

SOLUTION: A main frame 51 is formed into such shape that it is bent downward like character V at side view, this frame 51 is surrounded with a cover 26, and the height H1 from the ground surface of a bottom part 71 of the cover is made equal to an outside diameter D1 of a front wheel 5 substantially. Since the height of the bottom part 71 of the cover 26 surrounding the frame is substantially equalized to the outside diameter D1 of the front wheel 5, the main frame 51 is in a shape that is closer to a straight line than character U at side view so that the rigidity in the longitudinal direction is increased markedly. Since the height of the bottom part 71 of the cover 26 surrounding the frame is substantially equal to the outside diameter D1 of the front wheel 5, it is easy for a person to get on and off this vehicle in the same way as a scooter.  Consequently, it is possible to improve the rigidity of a vehicle body while maintaining the advantages of a scooter, thereby reducing the weight of a vehicle body frame 2.
