A bumper beam structure includes a beam extending transversely of a vehicle and right and left corned members attached to right and left ends of the beam. The beam is mountable to front ends of right and left vehicle frame members via the right and left corner members. The beam and the right and left corner members are all extruded members. The beam is disposed with its axis in an extrusion direction oriented transversely of the vehicle. The right and left corner members are disposed with their axes in an extrusion direction oriented vertically of the vehicle.

In a magneto-optical disk drive using a domain wall moving magneto-optical recording medium, a test-writing operation adjustment to deal wit dynamic fluctuation factors is minimized, and a reproducing or recording laser power is automatically optimized. A power of a light beam by which a domain wall starts to move is detected, and a power of a laser used to reproduce or record an information is corrected based on a change in the domain wall movement starting power. As the domain wall movement starting power, it is possible to use, for example, when the power of a light beam is varied, such a power as to maximize a rate of change of the amplitude of a reproducing signal.

A power driven circular saw includes a base able to slidingly contact a workpiece and a saw unit positioned above the base and supported by the base. The saw unit includes a motor case accommodating an electric motor, a handle extending from the motor case and able to be grasped by an operator, a circular saw blade rotatably driven by the electric motor and positioned to partly extend downward below the lower surface of the base, and a blade case for substantially covering the upper half of the saw blade. A power indication lamp is disposed on one side of the handle and is illuminated when power is supplied to the circular saw.

A digital audio decoder decodes or expands compressed data such as bit stream data, which are compressed based on the MPEG/Audio standard. Inverse quantization circuits perform inverse quantization on plural bit stream data, which are supplied thereto in connection with multiple channels respectively, thus producing inversely quantized data with respect to a prescribed number (e.g., thirty two) of sub-band samples respectively. The inversely quantized data are combined together among the multiple channels with respect to the prescribed number of the sub-band samples respectively. Then, a filter bank synthesizes together combined data corresponding to all of the sub-band samples, thus reproducing original digital audio signals. Multipliers are provided for use in gain control on the inversely quantized data with respect to the sub-band samples respectively. In addition, it is possible to additionally provide multipliers for amplifying the inversely quantized data of selected sub-band samples corresponding to low-frequency components of sound. This enables bass boost operations to be performed within the decoder. Surround effect processing circuits can be incorporated subsequently to the inverse quantization circuits, so desired surround effects are imparted to the inversely quantized data with respect to the sub-band samples respectively. The surround effect processing circuits simply contain multipliers whose coefficients are adequately controlled to achieve selective application of the surround effects among multiple channels.

A reflection type color liquid crystal display apparatus comprising a polarizing plate 1 having an absorbing axis 18, a birefringent plate 3, a liquid crystal layer 6 and a reflection layer 8 wherein the absorbing axis 18, a first orientation 14, a second orientation 15, a first optical anisotropic axis 16 and a second anisotropic axis 17 are set so as to form predetermined crossing angles .theta..sub.1, .theta..sub.2, .theta..sub.3, .theta..sub.4, and selected voltage values of at least three values are applied to the liquid crystal layer 6 from a multiplex driving circuit 10.Without using a color filter, a very bright chromatic color (white or black) is displayed at the time of an OFF waveform even in multiplex driving, and development of colors of very bright red, blue and green can be obtained with a selection voltage or an intermediate voltage between the selection voltage and a non-selection voltage.
摘要:
A process for detecting any defect in a ceramic body, including the steps of forming an electrically conductive layer in any such defects including fine voids present in the ceramic body, and then detecting presence or absence of the defect by measuring electrical conductivity between two given points shorted by the electrically conductive layer. The electrically conductive layer may be formed by penetrating an electrically conductive liquid into the defect. Alternatively, the electrically conductive layer may be formed by penetrating a penetrable liquid capable of forming the electrically conductive layer by thermal treatment or chemical treatment and thermally or chemically treating same.

A method for fabricating a solid-state image pick-up device changes part of the constituent elemental Si into the n-type impurity phosphorus P, thus changing the substrate to an n-type, by atomic transmutation through neutron irradiation of a p-type silicon Si wafer, and thus produces a Si substrate with a resistivity .rho..sub.s of 10 to 100 ohm-cm. or preferably 40 to 60 ohm-cm. A solid-state image pick-up device with a plurality of photosensors and vertical and horizontal shift registers as set forth above is then fabricated using the resulting Si substrate. In the preferred process, the silicon substrate can be obtained by irradiating a wafer sectioned from a crystal grown by the MCZ method, for instance, with neutrons as described before until it has the required resistivity .rho..sub.s. This silicon substrate is preferably of a p-type before neutron irradiation, that is, in the crystal growth state, and its resistivity .rho..sub.o is then ten or more times higher (100 ohm-cm. or more) than that .rho..sub.s obtained following neutron irradiation. For instance, if .rho..sub.s is to be 40 to 50 ohm-cm., .rho..sub.o should be 680 to 1180 ohm-cm. Then n-type impurities, e.g. phosphorus P are generated by neutron irradiation to convert the silicon substrate to n-type with a low resistivity of .rho..sub.S =10 to 100 ohm-cm., or of 40 to 50 ohm-cm.

The humidity sensor is highly sensitive over a wide relative humidity range, withstands a long use and presents almost no hysteresis in its humidity-resistance characteristics.
