Abstract: Disclosed is a method of manufacturing a semiconductor wafer or SOI substrate having TTV of 1 micrometer or less which is required to make a future semiconductor integrated circuit of high density. 
A semiconductor crystal disk (2; 12; 20, 21) made by slicing a semiconductor crystal ingot (1) is flattened by being subjected to a flattening step such as a grinding step (4), chemical-mechanical polishing or the like and then subjected to a step for providing an asymmetric configuration such as an orientation flat (OF) (12a, 21a) and the like. With this process, the deterioration of flatness due to the presence of the OF and the like can be prevented. Further, a flattening step conventionally carried out by a lapping step is replaced by surface grinding, by which the flatness of a wafer is improved and an etching step following to the lapping step can be omitted. The introduction of this process enables semiconductor wafers having a TTV of 1 micrometer or less and a diameter of 6 inches to be obtained at a yield of 90% or more. The application of the above method to an SOI substrate composed of two silicon wafers (20, 21) bonded through an insulating layer (22) can uniformly thin one of the silicon wafers to a few micrometers, whereby the practical use of a semiconductor integrated circuit of an SOI structure will be accelerated.

Abstract: There is disclosed a muting device of an upright piano which provides a bat (9), a wipen (3), a capstan button (6) and a muting mechanism (15). This bat rotates with a hammer (11) which strikes a string (13) of the upright piano. In addition, a jack (7) is provided to come in contact with a lower surface of the bat, and it rotates the bat in response to displacement of the key. This jack is supported by the wipen such that it can freely rotate. The capstan button is provided at a back edge portion of the key to transmit displacement of the key to the wipen. The muting mechanism is designed to reduce a string-striking stroke by rotating the hammer. Further, there is provided a key-displacement-transmission-rate changing mechanism (20). When reducing the string-striking stroke by the muting mechanism, this mechanism raises a displacement transmission point, at which displacement of the key is transmitted to the wipen, toward a rotation center of the key from the capstan button. Preferably, this mechanism is configured by another capstan button which is placed on an upper surface of the key at a position between the capstan button and rotation center of the key.

Abstract: Device (1) for digital signal processing, particularly video and image processing, comprising a linear array of processing elements (PE's) (2), an external controller interface (4), input/output ports (6), and an external memory interface (8). The input/output ports (6) allow interfacing to equipment such as digitizing cameras and video display monitors. Single instruction multiple data topology (SIMD) is used and incorporates two modes of communication: horizontal and vertical. Shift registers (10,12) provide horizontal parallel communication between the PE's in the linear array. There is one PE (2) for each digital sample, e.g. a pixel, and a sequence of data samples, e.g. a video line, can be processed in real-time. Each PE (2) includes a bit-serial arithmetic logic unit (14), a cache memory (18) and an external memory interface register (20). All communication within a PE (2) is along a one-bit wide bus, i.e. vertical mode, using a single move instruction with variable source and destination addresses. The processing capability of the device (1) is further enhanced by having a serial-parallel multiplier (16) in each PE (2). For applications requiring more PE's, two or more devices can be cascaded together. In another embodiment dual-port memories provide horizontal communication between the PE's in the linear array.

Abstract: A peak value detecting circuit comprising a peak voltage holding circuit, a voltage comparing section, a holding voltage control circuit, and a signal output circuit. The peak voltage holding circuit holds a peak value of an input signal voltage. The voltage comparing section compares the peak voltage held by the peak voltage holding circuit with an externally input signal voltage. The holding voltage control circuit controls the level of the peak voltage in accordance with the output given by the voltage comparing section as a result of the compare operation in the latter. The signal output circuit acts as a buffer in sending to the outside the peak voltage held by the peak voltage holding circuit. The output voltage from the signal output circuit is fed back as a reference voltage to a compare input terminal of the voltage comparing section. This setup prevents any offset that may develop in the signal output circuit from appearing in the output signal voltage of the peak value detecting circuit.

Abstract: A method for depositing dense, continuous, and adherent metal oxide films having a uniform composition is disclosed. An aqueous solution of soluble metal nitrate salts is formed, and nebulized into an aerosol of ultrafine droplets. A substrate having a thermal coefficient of expansion compatible with the metal oxide film is heated to about 280 ° to 320 ° C. The aerosol is sprayed on the heated substrate at a preselected velocity that overcomes the thermophoretic repulsion from the heated substrate. The aerosol spray is at a density that flash evaporates on the substrate to form a dense, adherent film of a desired composition without inducing cracking in the substrate. The substrate and metal nitrate film deposited thereon are post-heated to a temperature that partially oxidizes the film so that the film adheres to the substrate, about 450 ° to 550 ° C.

Abstract: An insert container (14) for a skeleton container (10) is dimensioned such that the container bottom (16) is only slightly smaller in terms of length and width than the access opening (22) formed at the upper edge of the skeleton container (10) by a frame-type enclosure (12). The end and side walls (18, 20) of the container diverge upwards in pairs such that the upper edge of the container rests against the side walls of the skeleton container below the enclosure (12) thereof. In order to insert such a container (14) in the skeleton container so as to be removable, its side walls must be sufficiently flexible and, by inward curvature of the side walls, the container cross section is reduced during the insertion operation to the extent that the container fits through the access opening (22). Due to the resilient construction of the container, the side walls subsequently snap back into their planar original positions. The upper edge of the container (14) is then overlapped by the enclosure (12) of the skeleton container (10). <IMAGE>

Abstract: A laser diode (10) in which a cathode is connected to the ground side of a positive power source and an anode is connected to the plus voltage side of the positive power source through a control circuit and whose light emission is driven such that its light-emission is controlled. A maximum current to drive the laser diode (10), for instance, a write current (I w ) is supplied to the laser diode by a disgorging type constant current source (12-1). In the reading mode, a differential current between the write current (I w ) and a read current (I r ) is sucked from the disgorging type constant current source (12-1) by a sucking type constant current source (12-2), thereby allowing the read current (I r ) to flow into the laser diode (10). In the writing mode, a current switch (14-1) is connected to the sucking type constant current source (12-2) of the differential current and is switched in accordance with write data. Further, in a manner similar to the laser diode side, the disgorging type constant current source (12-1) and the sucking type constant current source (12-2) are also connected through a current switch (14-4) to a photodiode (22) to monitor a light emission amount in a unit of the laser diode (10). An APC is made operative by a monitor light corresponding to a read power, thereby reducing a fluctuation of a light amount due to a temperature or a time-dependent change. In the reading mode, a modulation is executed at a frequency which is one or more digit higher than a frequency for the write data, thereby reducing influences by noises of the laser diode or backtalk noises.
