Abstract: An accumulator back pressure control device for an automatic transmission, the accumulator back pressure is regulated when a shift valve is switched. For example, when shifting up from the first to the second speed, when the second brake starts to engage by switching of the shift valve, rotation speed of the input side varies by the change of the output torque of a trans­mission gear mechanism. By detecting the rotation change by a sensor, the pressure control valve (linear solenoid) is control­led by signals from a control unit so that the control pressure from the pressure control valve is controlled at required moment. By this, for example, a control valve, by the change of hydraulic pressure at the control pressure port, regulates the pressure of oil source (line pressure port) and applies such regulated pressure to the back pressure chamber of the B2 accumulator to change the back pressure of the accumulator. When shifting from the second to the third speed, the back pressure of the C2 accumulator is controlled, and when shifting from the third to the fourth speed, the back pressure of the B0 accumulator is controlled. When down shifting, the operations are performed in same manner as the above.

Abstract: An IC card (10) has a processor (1) including an application program running signal generator (7) for generating a signal (9) indicating that an application program (42) is in operation and an inhibition address checker (5) for holding an address which is desired to be inhibited from being accessed or an address which is permitted to be accessed by the application program and producing an access inhibiting signal (8) when accessing is destined for the inhibition address. An access inhibition means (6) responds to both the application program running signal and access inhibiting signal to inhibit the processor from accessing the inhibition addresss when the application program is started or when it is under execution. Consequently, even in the event that the application program undergoes uncontrollable execution, access to addresses on a register (11) or a RAM (12) or the like storing system control information can be inhibited.

Abstract: A method and apparatus that distinguish a valid touch from an optical aberration caused by unwanted objects and/or scratches in the light plane of an optical touch panel device are disclosed. During a training mode the device learns the relative position of "aberration dropouts" caused by the unwanted objects. During normal operating mode the relative positions of "touch and aberration dropouts" are generated and compared with the relative position of aberration dropouts to distinguish between aberration dropout signals and touch dropout signals. The touch dropout signals are subjected to further processing to determine the precise location of a touch while the aberration dropout signals are discarded.

Abstract: It is already known to induce a voltage into the coil to be tested (test specimen) by means of an exciter winding in an exciter circuit, the stray field generated by a winding with shorted turns due to the short-circuit current flowing in it inducing a voltage in a measuring coil of a measuring circuit. In the prior art, either an auxiliary winding is required, to which a calibration device is connected which is adjustable with respect to the phase angle of the current emitted, or the indicating device itself must be phase-sensitive. In both cases, a sufficiently accurate measurement is possible only at low frequency. According to the invention, the measurement is carried out at such a variable frequency that the voltage is a minimum when the test specimen is faultless. In the associated device, having a first limb-type core with an exciter winding and a second limb-type core with a measuring winding, and an indicating device connected thereto in an arrangement such that the limbs of the two limb-type cores can be encircled by the winding to be tested (test specimen), the limb- type cores (10, 20, 40) and the yokes (11, 21, 41) closing them consist of ferrite and an air gap (12, 22, 42) is formed between the limb-type cores (10, 20, 40) and the yoke (11, 21, 41) closing them in each case.

Abstract: Short-circuits occurring in printed-circuit boards can be obviated by separating the respective short-circuit zones. In the event of subsequent connection modifications, conducting paths (Ls) must frequently also be separated in order to be able to use connecting surfaces (Af2) connected thereto as supporting points for a wiring modification. In both cases, on the one hand complete separation must be ensured while, on the other hand, damage to other parts of the printed-circuit boards, particularly the insulating layer located underneath it and the wiring layer underneath that, must reliably be prevented. This is achieved in that a stylus (St), consisting preferably of hard metal, is excited into ultrasonic oscillations (US) parallel to the surface of the printed-circuit boards (Lp) and in that separating joints (Tf) are then incorporated by metal-cutting in the short-circuit zones or conducting paths (Ls) using the stylus (St). The stylus (St) is in this case fed (V) parallel to the surface of the printed-circuit boards (Lp) while the advance (Z) is carried out vertically in steps. <IMAGE>
