Abstract: The features of this proposed invention contain the following item:
     1. To require the driver to pay attention to driving safety all the time.   2. When the driver is attentive, though the induction apparatus detects any objects, this proposed invention assists the driver just by means of alarming and downing speed;   3. When there are dangerous situations that the driver is not attentive, or that the driver won't step the brake pedal or step off from the accelerator while this car is too close to the front car or any objects come within a close distance suddenly, this proposed invention will brake automatically because of detecting automatically.   4. When the driver is not attentive or the induction apparatus detects any objects, this proposed invention will forthwith give warnings backwards to the following driver to make him/her on the alert.   5. When this car brakes automatically or the driver steps the brake pedal or steps off from the accelerator pedal, this proposed invention will transmit some certain frequency to the following car to make it receive; if the   following driver doesn't also step the brake pedal or step off from the accelerator pedal, thereupon the following car brakes automatically.   6. There is a forewarning device to forewarn anytime the following driver that "this car will brake automatically" to make him/her on the alert.

Abstract: A method of exposing a wafer to exposure energy such as ultraviolet rays or X-rays through a mask to transfer a pattern of the mask onto the wafer, for example. The temperature of the mask and/or the wafer increases during the exposure operation by absorption of the exposure energy. During the wafer being exposed, the temperature of the mask and/or the wafer is detected. If the temperature is going to exceed the exposable temperature range determined on the basis of the line width of the pattern to be transferred, the exposure operation is interrupted. Then, the heat accumulated in the mask and/or the wafer is removed. Thereafter, the exposure operation is resumed. This is repeated until the predetermined or required amount of exposure is reached, for one shot. By this, the thermal expansion of the mask and the wafer during the exposure operation is prevented to assure the precision of the pattern transfer.

Abstract: In complex networks, data frames may be routed through different systems having different frame or ad­dressing requirements. When the frames are transferred or bridged between such systems, known changes may have to be made in the frame contents to accommodate these require­ments. To maintain the integrity of error checking pro­vided by Cyclical Redundancy Checking (CRC) techniques, a system receiving frame modifies a Frame Check Sequence (FCS) field value only as a function of the known or planned changes to be made in the frame. If unplanned changes, that is errors, are introduced at the receiving system, application of standard CRC error checking tech­niques at the next system to receive the frame will indi­cate those errors.

Abstract: This invention describes a tunable optical filter to be used in an optical communication system. The filter of this invention has a pair of resonator cavities (18, 19) which are cascaded. The lengths (X, Y) of each of the cavities (18, 19) change simultaneously with the change in length (X, Y) of a piezoelectric sleeve (1) which contacts a reflective surface (4, 7) of each of the cavities (18, 19) through spacers (3). The sleeves (1) and spacers (3) are set so as to move the reflecting surfaces (4, 7) of the cavities (18, 19) along a single axis in response to a single control signal. When optical signals are passed through the two cavities (18, 19) and when the ratio of the length (X, Y) of the cavities (18, 19) is adjusted to a predetermined ratio of integers, the resonator cavity will resonate at a desired wavelength.

Abstract: An optical card recording/reproducing apparatus for recording/reproducing information onto/from an optical card by relatively moving the optical card to an optical head is provided. The optical head has an optical system for producing focusing and tracking control signals. The optical system includes a light emitting diode (119) having a narrow slit-like light emitting surface as a light source. The optical system has photo sensitive elements (125,126) for focusing control, a photo sensitive element for tracking control, and a recorded information reproducing photo sensitive element which are used to detect the reflected lights from the optical card of a slit light which is emitted from the light emitting diode. By forming a slit-like light spot onto the optical card, the focusing and tracking controls can be accurately easily executed and the deterioration in pits and track guides is prevented.

Abstract: A plasma process method and apparatus capable of operation significantly above 13.56 MHz can produce reduced self-bias voltage of the powered electrode to enable softer processes that do not damage thin layers that are increasingly becoming common in high speed and high density integrated circuits. A nonconventional match network is used to enable elimination of reflections at these higher frequencies. Automatic control of match network components enables the rf frequency to be adjusted to ignite the plasma and then to operate at a variable frequency selected to minimize process time without significant damage to the integrated circuit.

Abstract: A flat-pack type GTO thyristor (100) has an external cathode electrode (30) placed on a semiconductor element (1). The top surface of the external cathode electrode (30) has a three-level step configuration (33a, 33b, 33c). When a cathode member (51) of an external electric equipment is pushed onto the external cathode electrode (30), no force is applied to the lower two steps (33b, 33c) in such a step configuration. Consequently, it is prevented that the peripheral portion of the external cathode electrode (30) is deformed and the semiconductor element (1) becomes unstable in its gate characteristics.

Abstract: Apparatus is described which is capable of venting cerebrospinal fluid in the treatment of hydrocephalus or of shunting other body fluids. A surgically-implantable shunt valve (114) has a housing constructed of a surgically-implantable material with an inlet and outlet chamber within the housing. The housing includes inlet and outlet ports communicating with the inlet and outlet chambers respectively for connecting the inlet and outlet chambers to external catheters or other fluid conduits. An aperture (108) communicates between the chambers. The aperture has a circular periphery forming a circular valve seat. A valve member (110) of diameter larger than the circular valve seat is biased against the circular valve seat by spring means (116) adapted to keep the aperture closed until fluid pressure in the inlet chamber exceeds a preselected popping pressure and adapted to open the aperture when the popping pressure is exceeded so as to vent fluid through the aperture into the outlet chamber. An incremental magnetic adjustment (140, 142) means increases or decreases the amount of the bias in finite increments in response to pulses of applied magnetic field so as thereby to increase or decrease the popping pressure in finite increments. The incremental magnetic adjusting means cooperates with the spring means so as to increase or decrease its bias.
