Filed: 1993-06-21
Abstract: PURPOSE:To realize a digital tester in which the judgment of AC and DC to an input signal and the AC/DC switching of a measuring system can be automatically measured with high responsiveness, and a pulse width can be measured by treating the change of input potential as a change of potential area. CONSTITUTION:A potential area judgment part 40 outputs, as a potential area signal Sa, which area of potential areas A, B, D divided by standard voltages +1V, -1V an input potential VIN is situated, a start signal generating part 50 detects that the input potential VIN exceeds the standard potential and is switched to a different potential area from the potential area signal Sa, and outputs a start signal S1. Thereafter, a stop signal generating part 60 detects that the potential area is switched over the standard potential which the input potential VIN first exceeds from the potential area signal Sa and outputs a stop signal S2. A timer part 70 measures the pulse width of an input signal on the basis of the start signal S1 and the stop signal S2.

Title: Brake device for automobile
Inventor: FUKUDA HISASHI
IPC: B60T17/00
Filed: 1992-06-09
Abstract: PURPOSE:To prevent a brake operation feeling from changing by providing a control means for controlling an electric drive source so as to operate a vacuum pump when a state wherein deceleration of an automobile reaches a predetermined value is detected by an acceleration sensor. CONSTITUTION:When abrupt brake operation is detected by an acceleration sensor 14, a pump motor 10 is operated to feed negative pressure to a vacuum tank 5. In comparison to the case where the pump motor 10 is operated based on negative pressure of the vacuum tank 5, operation of the pump motor 10 is started at an earlier point of time to suppress lowering of the negative pressure and expedite recovery of the negative pressure. With this constitution, degradation of braking performance due to shortage of the negative pressure in the vacuum tank 5 is prevented at the time of abrupt brake operation as well as brake operation immediately after that.

When it is judged under running in the D range to need further drive output for ex. on a slope, the necessary power is generated for ex. by pushing the selector switch 21 for the 2nd range. If the shift lever 3 is operated into the N, R, P ranges, switch box 9 is retracted in the instrument panel 1 by the cable 13 against the action of the spring 29, which puts the switches 21, 23 into out of operability.

Title: Controller for active-seat suspension
Inventor: HAARAN UERUBAATO BAN JIYAAPEN
IPC: F16F15/04
Filed: 1981-09-22
Abstract: A virbometer 16 has a mass 50 suspended for vertical movement by a light spring 82 so that the mass tends to stay at a constant height reardless of angulations in the ground over which the vehicle carrying the system is travelling. The vibrometer provides one height signal by way of a potentiometer 46 and a second potentiometer 40 provides a second signal representing of the drivers seat 12. An error signal formed by a comparator 44 controls a hydraulic double acting actuator 18 so as to make the seat 12 follow the mass 50 and accordingly tend to maintain a constant height in absolute terms. In order to prevent the system becoming unstable when the ground is very rough, the mass opens limit switches 20, 22 at upper and lower limit positions and, when either switch is open, a relay 98 drops out and a solenoid valve 24 disables the actuator by connecting the two inlets 62, 64 of the actuator cylinder 60 together via a slow resistor. The relay is also deenergized when the ignition switch 26 is off. The potentiometers 46, 40 are connected between two circuit arms 36, 38 and a variable resistor 54 in the energising circuit provides gain control, ie sensitivity control. Ganged resistors 110, 112 in the two arms provide stiffness control and a resistor 116 solely in the arm 38 adjusts the main seat height. The relay 98 is of a latching relay which is reenergized by a reset switch 28. Operations of this switch sets the gain control resistor 54 to minimum gain. In a preferred construction of the vibrometer, the mass is suspended from the end of a lever arm projecting from one end of a torsion rod having the other end fixed.

Title: Production of magnetic head
Inventor: TAKAHASHI TAKESHI
IPC: G11B5/127
Filed: 1977-12-14
Abstract: PURPOSE:To simplify working processes and obtain a large volume of magnetic heads in a short time by providing winding holes at the central part of a magnetic material thin plate ribbon, locally heating the central part thereof to degrade magnetic permeability then cutting the ribbon to head chips. CONSTITUTION:An amorphous magnetic material thin plate ribbon 7 is mounted freely drawbly to a stock feeder and is delivered out at a specified speed. In the first process, winding holes 8 are punched at spacified spacings by a press 9 or the like in the apporoximate center of the ribbon. After working of the winding holes 8, the ribbon 2 is sent to the second process, where the approximate center of the ribbon is radiated in the moving direction by, e.g., a laser beam 11. Magnetic material, when heated, degrades its magnetic permeability considerably. The ribbon formed with gaps in this way is sent to the third process, where the ribbpn is cut in the direction perpendicular to the lengthwise direction of the ribbon between the winding holes. In this way, the working processes may be considerably simplified.
