Abstract: A mode-change mechanism for a tape recording and/or reproducing apparatus of the auto reverse type requires only one partially toothless gear with at least four, toothless peripheral portions in order to change modes of operation of the apparatus. The gear with the partially toothless peripheral portions is rotated only in one direction, and rotates in turn from each locked position to its next locked position in selecting the various modes of operation, so that a stop mode, a forward reproducing or recording mode, a reverse reproducing or recording mode, a fast forward mode, and a rewind mode are selectively obtained.

Abstract: An accelerometer has a moving magnet 6 within a housing 2. The magnet 6 is mounted within a support member 7 connected to the centre of a diaphragm 9 so as to permit movement of the magnet 6 along a measurement axis extending in the axial direction of the support member 7 by deformation of the diaphragm 9 and so as to permit movement of the magnet 6 along two mutually orthogonal measurement axes parallel to the diaphragm 9 by flexing of the diaphragm 9 to allow for pivoting of the support member 7. Furthermore displacement of the magnet 6 with respect to the three mutually transverse measurement axes in response to an applied force is sensed by a pickoff capacitor 14, and a respective output signal proportional to the component of the applied force along each of the measurement axes is supplied by associated sensing circuitry. Simultaneously the magnet 6 is restored to its null position by associated force coil pairs 30,32; 29,31; and 26,27. The use of a single magnet for measurement along the three axes renders the accelerometer of high accuracy and decreases the size of the measurement assembly.

Abstract: An electric storage battery is provided having a monitoring device for indicating the state-of-charge of the battery and particularly indicating whether a discharged battery is healthy and capable of being recharged or unhealthy and impending on a state of failure. The monitoring device achieves the foregoing by testing the open circuit voltage of the battery and determining if the voltage of the battery drops below a first preset value after application of a load and subsequently fails to rise above a second preset value after the load has been removed. Also, the monitoring device for the battery includes the capability of sensing when the battery has been placed into a system such as an engine system for an automobile and in response thereto modifying testing certain parameters. Preferably, the monitoring device is made integral with the battery case by providing a receptacle for receiving the device and a pair of connecting arms at least partially embedded in the battery container or cover.

Abstract: In the rotation sensor according to the invention, the stator (13), which is connected to a housing (12) is formed by two bearing flanges (6.1, 6.2), which are connected to one another preferably by screwing and are shaped such that in the connected state of the two bearing flanges an annular chamber receiving the component disc remains free. Preferably, the electro-optical scanning unit (15), which is aligned on the component disc (1), is also installed in corresponding recesses of the two bearing flanges. Due to the enclosure of the component disc and of the scanning unit by the bearing flanges, a very low overall height is achieved, on the one hand, and a high constancy of spacing between the component disc (1) and the scanning plate (2), on the other hand, so that it is possible to dispense with a condenser lens assigned to the light transmitter (5) of the scanning unit (15). In order to guarantee further stability and constancy of spacing, and to enable a simple construction, it is provided that the inner rings (11a) of rolling-contact bearings (11) supporting the shaft (7) are prestressed with respect to one another so as to increase the mutual spacing and are bonded in this state to the shaft (7). The outer rings (11b) of the rolling-contact bearings (11) are likewise fixed, preferably by bonding. <IMAGE>

Abstract: A diathermy unit has a power oscillator with a resonant circuit (16) arranged to be coupled to the load (12) represented by the tissue to be treated. The resonant circuit includes a capacitor (20) for connection in series with the load such that the resonant frequency varies with the load resistance. The resulting self-­tuning of the oscillator allows improved matching of the oscillator to the load (12) with consequent improved efficiency, a feature especially useful for a battery-­powered unit. Regulation of the output power of the unit makes use of a feedback loop including an analogue multiplier for receiving signals representative of the power of the output stage, the resulting product signal being used to control pulse width modulation of the oscillator.

Abstract: The magneto-optic recording and regenerating process and the device using it in accordance with the present in­vention are intended to magnetize the magnetized film of a disk parallel to the plane of the magnetized film to record or erase information. 
     When regenerating information, light beams whose in­cident plane is substantially perpendicular to the direction of magnetization of the recording medium is applied to the disk, so that the recorded information is regenerated depen­dent on the light intensity of reflected light obtained in response to the direction or magnitude of magnetization of said disk. 
     Additionally, light beams irradiated the magneto-optic disk including a magnetized film having a coercive force smaller than the saturated magnetization at room tempera­ture, so as to elevate the temperature of the magnetized film but not up to its Curie temperature, and then infor­mation is recorded on or erased from the magnetized film with its coercive force decreased by the elevated tempera­ture.

Abstract: A shared bus data processing system in which a plurality of potential bus masters can contend for time slot ownership on the shared bus on a priority basis is disclosed, wherein the current priority of each master is determined by comparing a count, adjusted monotonically in synchronism with the available time slots, is compared with one of a pair of stored boundary values for that master and, if that master is contending, is the priority value for that master if the current count is found to lie within the comparison boundary value, else is deemed to be the other stored boundary value. The stored boundary values and the initial count for each potential bus master are all programmable whereby "round robin" priority is obtainable by setting the stored boundary difference equal to the number of potential bus masters in the round robin and the initial counts to lie within the boundary difference and to be representative of the position within the round robin priority order of the particular potential bus master to which relates and fixed priority is obtainable by setting the two stored boundary values for a potential bus master to be equal.

The yoke portion (38) is formed integrally with the track portion (26) so as to extend from one end of the track portion remote from the bearing portion, and has a protrusion (28) of the same height as the track portion. The width of the protrusion (28) is smaller than that of the bearing portion (24) and larger than that of the track portion (26). The stepped portion (46) is formed so as to surround at least the track portion and the protrusion of the yoke portion, and has a surface which is spaced apart from top surfaces of the track portion and the protrusion by a distance nearly equal to the height of the portions (24,26,28). The bearing, track and stepped portions and the protrusions are formed by etching the surfaces of two bonded ferrite blocks, through an etching mask pattern corresponding to the desired configuration to be formed.
