Abstract: A semiconductor memory device includes a redundant memory cell, an electrode and an output circuit. The redundant memory cell is used instead of a memory cell when the memory cell has a defect. The electrode applys with a test signal for setting a test condition from outside in testing the redundant memory cell. The output circuit outputs data read out of the memory cell and the redundant memory cell. When the test signal is applied to the electrode to set the test condition for the redundant memory cell, the output circuit is configured to output data read out of the redundant memory cell at a level different from a signal level of data readout of the memory cell for output.

Abstract: An impact force is transmitted to a tip end tool due to the changes of the air pressure within an air chamber generated by the reciprocal operation of the piston within a striker. The attachment portion of a tip end tool holding member for holding the tip end tool to a cylinder casing is sandwiched between buffers disposed in the two directions of the axial direction of the tool thereby to elastically support the tip end tool holding member to be movable in the two directions of the axial direction of the tool.

Abstract: In a method for protecting a test program, a source file is translated using a primary key owned by a program provider to create a distribution file and a secondary key so that an object file of the test program can be created only when the distribution file and the secondary key are used. Further, in an LSI test method, a test pattern is created from a source file and a scramble format, to decide whether a signal, sent from an LSI, of response to the test pattern is right or wrong based on a test plan.

Abstract: A digital reproduction signal processor relating to the present invention is provided with an analog/digital converter 4 for sampling an analog reproduction signal at a period which is longer than a digital recording channel rate, to convert to a low rate digital reproduction signal having a period which is longer than a recording channel rate, a coefficient setting unit 6 for performing a digital filtering with keeping the low rate, to generate a digital equalization signal, and an interpolator 7 for interpolating a reproduction data of the digital recording channel rate, and a half-rate Viterbi decoder 8 for taking out data. According to the digital reproduction signal processor constructed as above, even when a digital read channel employing a PRML is employed, the analog/digital converter 4 or a digital circuit operated at a channel rate can be eliminated, thereby to provide a reproduction signal processor operating with low power consumption and of low cost.

Abstract: In a digital recorded data reproduction which applies PRML signal processing, it is an object to enhance a reproduction signal quality and a playability for an abnormal signal by an offset correction and a phase-interpolation-type digital phase-locked loop. A prescribed frequency band of a reproduction signal is emphasized by a waveform equalizing unit 2, and its output signal is sampled by an asynchronous clock at an analog/digital converter 3. After a sampling signal is subjected to the offset correction, PR equalization is performed by a transversal filter 6 and a tap weighting factor control unit 8 which applies LMS algorithm, and a signal of a regular sampling phase is reproduced from its output signal by a high-order interpolation filter 7 employing a digital phase-locked loop 11. The reproduced signal in a regular phase is demodulated by a maximum likelihood decoder 12, thereby to reproduce digital data recorded on a medium.

Abstract: An image displaying apparatus stores plural image data and displays one of the image data, which image data represent a growing plant (animal) or represent a series of motions of an animal. The apparatus further stores plural element data for growing the plant (animal). When one of the element data is selected, another image data of the plant (animal) is displayed in place of the previously displayed imaged data to show how the plant (animal) grew up thank to the selected element data. The apparatus is provided with a sensor for detecting motion of a user. Detecting the motion of the user, the apparatus displays new image data representing a motion of the animal in place of the previously displayed image data to show how the animal reacts to the user's motion.

Abstract: A data search apparatus is capable of searching for a face image, character data corresponding to the face image, and/or a combination of the face data and character data, based only on part of the data which compose the face image. In such case, one or more part data, such as eyes, nose, etc. composing the face image is designated by a key input unit, and image data including part data which coincides with the designated part data, is read out from memory. The found face image is then displayed on a display unit, along with character data corresponding thereto.

Abstract: An apparatus for purifying contaminated air has an air inlet exposed to a road surface, an air outlet spaced from the road surface, a soil bed for being populated with microorganisms, the soil bed being disposed between the air inlet and the air outlet and allowing air to pass therethrough, a pipe interconnecting the soil bed and the air outlet, and embedded underground, and a fan for introducing air from the air inlet, passing the air through the soil bed, delivering the air from the soil bed through the pipe to the air outlet, and discharging the air from the air outlet.

Abstract: Contaminated air, e.g., air contaminated by exhaust gases from automobiles and factories, is purified by passing the contaminated air through a soil layer populated with microorganisms. The contaminated air is humidified before the contaminated air is passed through the soil layer or while the contaminated air is being passed through the soil layer. The soil layer may be warmed, or ozone may be supplied to the contaminated air to oxidize nitrogen monoxide in the contaminated air into nitrogen dioxide before the contaminated air is passed through the soil layer.

Abstract: An object image display device which changes and displays the image of an object such as an animal or a building. A display displays an object image including a combination of patterns of the parts of the object. The pattern of at least part of the object image displayed on the display is successively changed to a different part pattern of the same at least part in response to the keying operation of keys. Thus, the display displays the object image such that the at least part of the object image successively moves. The user is able to set a shape to which the object image is changed and the timing of changing the object image. Each time the object image is changed, a voice corresponding to the aspect of change of the object image is output sequentially to the outside. Externally inputting a voice into the device changes at least a part of the object image displayed at present in accordance with the contents of the input voice.
