IPC: G10L19/00
Filed: 1995-01-24
Abstract: A digital signal processing apparatus and a method for carrying out a re-quantization process for turning an inputted digital signal into a digital signal with a smaller bit number includes a signal generator (10) and a re-quantization processor (13). The signal generator has a data generator (1), a delay circuit (2) and an adder (4) and generates a dither signal for which an amount of a high frequency component is larger than that of the low frequency component. The data generator (1) generates M-series data-like non-correlating data. The delay circuit (2) delays the output from the data generator (1). The adder adds (4) the output from the delay circuit and an output from the delay circuit for which the polarity has been inverted (3). In the re-quantization process, the dither signal from the signal generator and the inputted signal are added (12) and the added signal is then re-quantized (13).

Abstract: A vertical-type multicylinder engine (3) includes a plurality of combustion chambers (21a), an inlet muffler (50) having a plurality of air intake passages (53a), and a blow-by gas entry opening (58) for introducing a blow-by gas into the muffler, and a plurality of throttle valve devices (61) provided downstream of the intake passages and upstream of the valve devices in corresponding relation thereto. The inlet muffler has a plurality of blow-by gas distributing paths (S1-S5) that are formed inside the muffler to distributively direct the blow-by gas introduced via the blow-by gas entry opening to the corresponding throttle valve devices. Thus, the entry opening, distributing paths and intake passages of the muffler and the throttle valve devices jointly define a structure for returning the blow-by gas to an upstream portion of the engine intake system. The distributing paths have different sizes that become progressively greater as the respective distances, from the blow-by gas entry opening, of the paths increase. The blow-by gas returning structure thus formed serves to minimize inter-cylinder differences in the amounts of blow-by gas flowing into the individual throttle valve devices and hence in combustion conditions in the combustion chambers.

Abstract: An engine compartment cooling fan provided in an engine compartment is controlled by a control unit, to be placed in its ON or OFF state, on the basis of an output from an engine compartment temperature sensor. The control unit continues the control of the engine compartment fan for a predetermined period of time after a key switch is turned off, with power supplied from a battery through a by-pass line. This permits the engine to be re-started without difficulty even after a short time of stop of the vehicle. Upon lapse of the predetermined time, the control unit disconnects the power supply through the by-pass line and stops its operation. Since there is no power consumption after the end of the operation of the cooling fan, unnecessary consumption of the battery can be avoided.

Abstract: A monolithic microwave integrated circuit (MMIC) downconverter for a direct broadcast satellite low noise block downconverter has a mixer that produces sum and difference frequency signals from an oscillator signal and a radio frequency (RF) signal. An intermediate frequency (IF) signal is obtained by selecting the difference signal of the sum and difference frequency signals using a low pass filter. An amplifier circuit coupled to the low pass filter amplifies the IF signal from the low pass filter. A switchable oscillator frequency signal circuit is connected to the mixer, providing one of two different oscillator frequency signals for mixing with the radio frequency signal.

Abstract: A method and apparatus for managing texture mapping data in a computer graphics system, the computer graphics system including a host computer (15), primitive rendering hardware (12, 14) and a primitive data path (18) extending between the host computer and the primitive rendering hardware. The host computer passes primitives to be rendered by the system to the primitive rendering hardware over the primitive data path. The host computer has a main memory (17) that stores texture mapping data corresponding to the primitives to be rendered. The primitive rendering hardware includes a local texture memory (48) that locally stores the texture mapping data corresponding to at least one of the primitives to be rendered. When a primitive passed to the primitive rendering hardware is to be rendered, a determination is made as to whether its corresponding texture mapping data is in the local texture memory. When the texture mapping data corresponding to the primitive to be rendered is in the local texture memory, the primitive is rendered using its corresponding texture mapping data from the local texture memory. When the texture mapping data corresponding to the primitive to be rendered is not in the local texture memory, the texture mapping data corresponding to the primitive to be rendered is downloaded from the host computer main memory to the primitive rendering hardware, and the primitive is rendered using its corresponding texture mapping data downloaded from the main memory. The local texture memory map be implemented as a cache.

Abstract: A digital video recorder or player performs error correction coding and decoding in two separate or paged memories (156,158). During a first phase of operation, previously error-corrected or error-encoded data is read from a first memory (156) while simultaneously new data to be error-encoded or error-corrected is stored in the first memory (156). Meanwhile, the second memory (158) is used for error-encoding or error-decoding of previously-stored data. In the second phase, the memories reverse roles; the data stored in the first memory (156) is error-encoded or error-corrected while previously error-corrected or error-encoded data is read from the second memory (158) and replaced with new data to be error-encoded or error-corrected. These phases are performed in an alternating fashion throughout a record or playback operation.
