Abstract: A device for lowering and holding the free end of a vehicle folding top, cover or the like in a closed position on the frame contains engagement elements (23'), provided on the vehicle folding top or the like, for the engagement in each case of one retaining hook (5') provided on the frame. The retaining hook (5') is coupled to the actuation rod (11') of a drive device and can be moved by said device between a raised engagement position and a lowered locking position. The retaining hook (5') has an engagement area (7') for a pivotably mounted locking catch (13') which engages in a locking manner with the engagement area (7') of the retaining hook (5') when the retaining hook (5') moves into the locking position and which, when the actuation rod (11') moves, is moved so as to disengage from the retaining hook (5') in order to move the retaining hook (5') out of the locking position. The actuation rod (11') is coupled to the retaining hook (5') via an elongate coupling area. The movement of the actuation rod (11') for the purpose of moving the retaining hook (5') out of the locking position causes the locking catch (13') to disengage from the retaining hook (5'). <IMAGE>

Abstract: A laser interferometer forms for an electronic evaluation circuit a sinusoidal and a cosinusoidal input signal having a high dc component. In order to suppress the latter so that an exact evaluation of the measurement signal components is possible, the input signals are connected in each case to an input of a differential amplifier (15, 29). The outputs thereof are connected via a pulse shaper (16, 30) to an up-down counter (17) and to circuits (18, 31) which form digitised dc values from the dc components. The respective digitised dc value is fed back via a microprocessor (27) and a digital-to-analog converter (28) to the other input of the relevant differential amplifier. The microprocessor (27) passes on a varying dc value only when a specific counting frequency of the counter (17) is exceeded. <IMAGE>

Abstract: MOSFET devices (82) or circuits (80) incorporating an improved substrate temperature sensing element (94) are obtained by forming a PN junction (J2) directly on a thin (gate) dielectric region (140). The temperature sense junction (J2) is desirably formed in a poly layer( 134). By mounting it directly on thin (gate) dielectric (140) its thermal response to temperature changes in the substrate (111) is improved while still being electrically isolated from the substrate (111). It is desirable to provide over-voltage protection elements (100) coupled to the junction (J2) to avoid rupture of the underlying thin dielectric (140). Because the sense diode (94) and all the over-voltage protection devices (102) may be made of poly (136,138,144) with junctions (J2) perpendicular to the substrate (111), the structure is particularly compact and simple to fabricate.

Abstract: The horizontal synchronizing signal seperation circuit extracts pulses indicative of horizontal synchronizing timing from a composite synchronizing signal which includes a horizontal synchronizing signal and a vertical synchronizing signal. When detecting the rising edge of the composite synchronizing signal, a rising edge detection circuit generates a pulse signal. A counter counts the number of the pulses in a clock signal. The output of the counter is supplied to a decoder which decodes the output of the counter and outputs timing signals. Using the timing signals, a control signal is generated to control a gate to which the output of the rising edge detection circuit is supplied. The output of the gate is used for generating a separated horizontal synchronizing signal.

Abstract: Scanning electrodes (L) constituting a ferroelectric liquid crystal panel (20) are divided into a plurality of scanning electrode groups, and a selective voltage (VCA) is applied sequentially to the scanning electrodes constituting the scanning electrode group over two group fields. In a first group field, a signal voltage (VSC) for changing picture elements on the selected scanning electrode from the bright display state to the dark display state, or a signal voltage (VSE) for not changing the bright and dark display states is applied to the signal electrodes. In a second group field, a signal voltage (VSD) for changing the picture elements on the selected scanning electrode from the dark display state to the bright display state, or a signal voltage (VSE) for not changing the bright and dark display states is applied to the signal electrodes. Uniting the two group fields together, changes in display state of the picture elements constituting the scanning electrode group are responded. Thereby, as long as the display state of the picture elements is not changed, the change in effective voltage waveform applied to the picture element can be kept smaller than the change in effective voltage waveform due to switching of the driving voltage combination corresponding to the two group fields.

For example, when the input color image falls within the color reproduction region of the output apparatus, color reproduction color-matched with input color image signals is performed. When the input color image falls outside the reproduction region, color reproduction is performed by color conversion processing assuring highest color reproducibility.
