IPC: H04N5/911
Filed: 1992-05-29
Abstract: A picture quality correcting device which no longer relies solely on the frequency characteristic for picture quality correction, and which prevents disturbance in the group delay characteristic occurring due to a large variation in the frequency characteristic of the luminance signal, thereby greatly decreasing deterioration of picture quality of the played-back image. A noise component from the luminance signal is extracted by a noise canceller. Then, the noise component is deducted from the luminance signal by inverting the polarity of the noise component and composing it with the luminance signal. The high-frequency component of the luminance signal released by the noise canceller is corrected by a picture-tone circuit. The amount of noise suppression of the noise canceller and the amount of correction of the high-frequency component of the picture-tone circuit is made variable according to a control voltage by adjusting a picture quality adjuster. The amount of noise suppression of the noise canceller is adjusted, for example, according to a limiting level setting voltage generated by an LLC circuit.

Abstract: A centrifuge is proposed, having a changeable rotor (10) which is driven by an electric motor (11), code elements (14) which are arranged in an annular shape being arranged on the rotor (10) and being sensed by a sensor (15) which is fixed to the housing. A decoder device (17) serves to detect the respectively mounted rotor (10) as a function of the arrangement of the code elements (14). The number of code elements (14) is proportional to the maximum permissible speed of revolution of the respective motor (10). A safety device (18) which compares the frequency of the sensor signals (number of code elements 14 which pass per unit of time) with a predetermined fixed frequency value is additionally connected to the sensor (15), it being possible to trigger a deactivation of the electric motor (11) when the fixed frequency value is reached or exceeded. In this way, the same code elements and a single sensor (15) serve to detect the respective rotor and to perform emergency deactivation of the electric motor (11). <IMAGE>

Abstract: An LED printer, after power-on, take steps a1 to a6 for preparation and then steps a7 to a9 for printing operation. In controlling the printing operation at step a9, the temperature of a fixing unit is detected by a thermistor or the like. Collection of these various data is accomplished by providing a step for counting the number of executions of the operation in the operation executed every one-millisecond and by converting the number of executions thus counted into an elapsed time. The configuration of the processing apparatus is thereby remarkably reduced in size.

Abstract: In a digital cellular communication system, a cell-site station transmits a frame containing a fixed number of burst signals each having stealing flag bits indicating that the frame is a traffic channel (TCH) or a fast associated control channel (FACCH). A mobile station receives delay-dispersed burst signals and equalizes their delay-dispersal effects to produce soft information so that each of the transmitted stealing flag bit is represented by a multibit value. A channel discriminator provides a total sum of all the multibit values of the received burst signals and compares the sum to a threshold value to identify the received frame as a FACCH if the sum is equal to or greater than the threshold value, or identify it as a TCH if the sum is smaller than the threshold value.

Abstract: For a balance adjustment due to a reduction in size and weight of an actuator, an arm portion, an axis attaching portion, and a coil supporting portion are arranged so that the centers of gravity on the coil side are located on a straight line connecting a rotational center and the center of gravity on the head side. Further, the improvement of an assembling efficiency of a VCM, an increase in torque, a one-touch fixing of an FPC connecting band, a noise prevention of a read pattern, and an insulation between the base and cover due to a bias of an MR read head are accomplished. A sector mark is detected by comparing a peak detection pulse and its reference polarity signal. A redundancy is provided to a reference detection polarity signal so that a read signal can be detected even if any one of the read signals of the sector marks is dropped out. A gray code detecting section for recognizing a cylinder address also detects on the basis of a peak detection pulse and a polarity signal due to the reading of a gray code. A memory space to store a program is divided into an ROM space of a small electric power consumption and an RAM space of a large electric power consumption and stores each peculiar program. When the CPU doesn't execute a program in the RAM space, the execution of an idle program in the ROM space is allocated, thereby reducing an electric power consumption in an idle state by using an ROM.

Abstract: A computer system with a multiplexed address bus that is shared by both system memory and by slave devices is described. The slave devices are incorporated into an existing system memory configuration by providing a bus controller to execute a two-cycle address sequence on the multiplexed address bus. The address sequence is followed by a transfer of data. A random latency can exist between the time of receiving address information and the time of receiving data corresponding to the address information. This random latency can be exploited by the system CPU for other computational purposes. The bus controller of the system executes multiple, or pipelined, data writes to the bus before an acknowledgement for the first data write is received. In this scheme, the acknowledgement for the first data write is typically sent during the same time period that the subsequent data writes are being received. Consequently, data transfer acknowledgements overlap data writes. This overlapping operation allows the bus to be completely utilized during write operations, thereby improving data bandwidth.
