Abstract: A compressor device for a refrigerant cycle includes a compressor and a control unit. The compressor is provided with a displacement changing mechanism for changing its displacement. The control unit changes a current value supplied to the displacement changing mechanism, thereby relatively changing the displacement of the compressor. In the compressor device, when a rotational speed of a vehicle engine is lower than a predetermined rotational speed, the control unit controls an upper limit of the current value between a first predetermined value and a maximum value. Accordingly, a displacement specification of the compressor device can be normalized for vehicle engines having different power outputs, while engine stall can be prevented.

Abstract: A capacitive dynamic quantity sensor includes a semiconductor substrate, a weight, a movable electrode, and two fixed electrodes. The weight is movably supported by the semiconductor substrate. The movable electrode is integrated with the weight. The fixed electrodes are stationarily supported by the semiconductor substrate. The fixed electrodes face the movable electrode to provide a narrow gap and a wide gap and form a detection part having a capacitance. The weight and the movable electrode are displaced relative to the fixed electrodes in response to a dynamic quantity to be detected such that one of the gaps increases while the other decreases. The dynamic quantity is detected on the basis of the variation in the capacitance. One of wide gap electrode surfaces, which define the wide gap, is smaller than narrow gap electrode surfaces, which define the narrow gap, to improve sensor sensitivity.

Abstract: A method for conveying application data via carrierless ultra wideband wireless signals, and signals embodied in a carrierless ultra wideband waveform. Application data is encoded into wavelets that are transmitted as a carrierless ultra wideband waveform. The carrierless ultra wideband waveform is received by an antenna, and the application data is decoded from the wavelets included in the waveform. The waveforms of the signals include wavelets that have a predetermined shape that is used to modulate the data. The signals may convey, for example, Web pages and executable programs between mobile devices. The signals are low power and can penetrate obstructions making them favorable for use with a wireless node of a network.

Abstract: The power supply PS includes a voltage detecting circuit VD for detecting a voltage level Vs inputted from an external voltage source, a boot strap circuit BS, andET connected in parallel with BS, a smoothing circuit SM connected with the BS output terminal and a regulating IC connected with BS and FET. The regulating IC includes VD, a transistor Tr and condenser C. Both when a PS switch is turned on and when VD detects that Vs (which once descended) reaches an ascending reference, a high level driving signal generated by VD is changed into a low level signal, thereby turning off Tr connected with C. Thus, until Tr completes charging up C, a duty ratio of a pulse width modulation (PWM) signal dependent on the SM output is made gradually greater, thereby surely preventing a rush current by turning on and off the FET by the PWM signal.

Abstract: A semiconductor dynamic sensor such as an acceleration sensor is composed of a sensor chip having electrodes movable in response to acceleration applied thereto and a circuit chip having a circuit for processing signals fed from the sensor chip. The sensor chip and the circuit chip are contained and held in a packaging case. The sensor chip and the circuit chip are fixedly connected via an adhesive film. The sensor chip is correctly positioned on the circuit chip without creating misalignment relative to a sensing axis, because the adhesive film from which an adhesive material does not flow out under heat is used. A semiconductor wafer including plural sensor chips is first made and the adhesive film is stuck to one surface of the wafer, and then individual sensor chips are separated by dicing. The sensor chip is connected to the circuit chip via the adhesive film.

Abstract: In a capacitive type dynamic quantity sensor, a width of a beam in a beam portion extending in a direction that is perpendicular to a predetermined deformation direction and a gap disposed between a movable electrode and the fixed electrode in the predetermined deformation direction are approximately identical. Accordingly, manufacturing error is prevented from affecting the sensitivity of the capacitive type dynamic quantity sensor. For example, a manufacturing tolerance error of ±2.5% is allowed as a result of designing the width of the beam and the gap to be identical in length.

Abstract: In an airbag cover having an ornament, mounting legs of the ornament are inserted individually into mounting holes formed in a door portion of the airbag cover and are bent at first bent portions near the opening of the mounting holes on the rear side of the door. The leading end portions of the mounting legs are bent at second bent portions arranged near the leading ends of the mounting legs, on the rear side of the door.

Abstract: A vehicular communications system connects, through a communications network, with a plurality of electronic control units (ECUs) that control respective in-vehicle devices. The vehicular communications system further connects with a master ECU that monitors, for diagnosis, operating states of the ECUs through the communications network. When the master ECU detects a given ECU that is in an abnormal state, it restarts, through the communications network, the given ECU to return to an initial state. When the master ECU initializes the given ECU, it stores a record of initializing the given ECU in its EEPROM, and initializes, when necessary, a built-in memory of the given ECU. The master ECU can be constructed as initializing the given ECU based on an initialization request command from an outside of the vehicle through wireless communications.

Abstract: A vehicular brake apparatus, which is provided at a shaft of a motor that revolves due to depression of a brake pedal, has a variable gear mechanism including a non-circular spur gear that changes a reduction ratio from a high gear ratio to a low gear ratio along with revolution. Revolution is converted to linear movement by roller bearings interposed between two ramp portions each having a straight inclined surface, and a friction member is pressed against a disk by a friction material holding portion being moved in a straight direction. Further, a braking force is generated on the disk by the friction member and another friction member provided on the opposite side of the caliper.

Abstract: A brake operation amount detection device detects an operation amount of a brake pedal, and a target deceleration computation device computes a target deceleration corresponding to an operation amount that the driver intends to achieve. Further, an actual deceleration calculation device calculates an actual deceleration. A deviation between the target deceleration and the actual deceleration is obtained as a difference level, and a warning issuing device generates a sound having a volume that increases in accordance with the magnitude of the difference level. Accordingly, in the case that the brake does not act, contrary to the driver's expectation, even when the driver presses down the brake pedal, the driver can recognize a degree of difference from the driver's braking intention, based on the magnitude of the sound. Therefore, the driver does not feel a sense of danger or fear.

Abstract: An apparatus is for inhibiting fuels from flowing out of fuel tanks, and includes a housing having an evaporator opening and a fuel opening, a double-floating valve and a cover having a cylinder-shaped liquid receptacle. Alternatively, the apparatus can include a housing having an evaporator opening, a fuel opening and a substantially cylinder-shaped dam, a double-floating valve, and a cover free from the cylinder-shaped liquid receptacle. The apparatus can securely inhibit liquid fuels from flowing into a canister even when liquid fuels spout through the valve hole and the evaporator opening, because liquid fuels collide with the liquid receptacle or the dam to return back into fuel tanks through the evaporator opening.
