Abstract: PROBLEM TO BE SOLVED: To improve the capability of a coder, while using a mental acoustic masking effect by providing an analytical/composite window pair with a sufficient degree of converting frequency selection. SOLUTION: The composite window of data generates a composite response, so that the product of that response and the response of the synthetic window of an encoder is a total of '1' concerning two overlapped adjacent sample blocks. Adjacent time area signal sample blocks are overlapped and added, and the effects of analytical and composite windows are canceled. The encoder is converted into a frequency area by discrete transformation similar to a single side wave band analytical/composite system to which sampling 101 is performed critically. Two conversions 103 are even-number of times piling time area aliasing cancel TDAC and odd-number of the times piling TDAC and a converting coefficient allocates and non-uniformly quantizes fixed and veriable bit numbers based on psychological acoustic masking.  It is not necessary to transmit subordinate information concerning adaptive allocation bits, and an error code and data to be protected are spread over all the entire frame output.

Abstract: PURPOSE:To suppress clip processing and reduce the influence of a foldover noise by detecting the maximum value of an input signal, calculating its reciprocal as an attenuation coefficient by approximation when the detected maximum value is exceeded, and adding a specific value to a last attenuation coefficient and obtaining a new attenuation coefficient when not. CONSTITUTION:An arithmetic control circuit 7 performs repetition until the value of a register 2 reaches 0, decides that a monitor period ends when the value of the register 2 becomes 0, and stores a value corresponding to the monitor period in the register 2 again. Then the value stored in a register 1 is regarded as the maximum value of the monitor period and stored in a register 3, and the register 1 is cleared. When the maximum value is large, the reciprocal of the found maximum value is stored as an attenuation quantity in a register 6. When the maximum value is small, a certain quantity is added to the attenuation quantity in the register 6 which is set last to obtain a new attenuation quantity. Consequently, the clip processing is suppressed and the influence of the foldover noise is reducible.

Abstract: A communication channel assignment method is disclosed in a cellular mobile communication system in which, instead of assigning communication channels in a fixed manner in each cell, whenever there is a demand for assignment of a communication channel to be used between a base station and a mobile station, channels are assigned by merely measuring the ratio of the desired signal to the interference signal at these two stations without checking interference in nearby cells and, if there is surplus in the reception level, transmission power can be lowered. In this communication channel assignment method, channels are selected in a particular order or its reverse that is identically established for all cells depending on whether the transmission power is less than or greater than a specified value. <IMAGE>

Abstract: A test tube handling assembly has an elongate member (12) with an end for engaging a test tube (14) and an end opposite thereto driven about an axis of the member for orbital movement with its axis. The member is a slender rod with a spherical bearing about a center part thereon between the ends thereof and along its axis. An arm (23) extends from a support to carry the spherical bearing and permit limited motion of the rod relative to the support. A gripping means (28) on the end for engaging the test tube holds the test tube and its contents during movement of the rod relative to the axis. A drive (34) located on the support near the end opposite causes the test tube to swing about the center part. Contacting means with a seal for closing the open end of the test tube is part of an inflatable bladder (32) which holds the open end of the test tube by fitting in the open end of the test tube. The drive has a motor (35) for providing orbital motion. The motor axis (36) and the member axis (16) are in spaced parallel relation relative to each other with a linkage means therebetween to cause the axis of the member to move about the axis of the motor imparting an orbital motion to the end opposite of the member thereby orbiting the end for engaging the test tube. A three axis positioning means (19) carries the support by connection with a releasable latching means. A method has steps of holding a test tube by the gripping means, moving the test tube repetitively with the drive and generating orbital movement of the test tube and sample therein for producing a vortex in the test tube sample.

Abstract: PROBLEM TO BE SOLVED: To reduce the size and output high voltage without the need for output transformer, and reduce higher harmonics to the load side by connecting the unit inverter cell in each phase with an input transformer having multiple winding on the secondary side out of phase. SOLUTION: A secondary winding 3S of an input transformer 3 comprises three sets of windings constituted in 18 phases, shifted from one another by an electrical angle of 20 degrees, and an individual unit of them is connected with the same stage of unit inverters constituting the respective phases. Even if an n-th stage in each phase is bypassed, the harmonic components in input current become identical without disturbing the 18-phase constitution. The input transformer 3 having the plurality of the secondary winding 3S and the unit inverter cells 4U1-4U3, 4V1-4V3, 4W1-4W3 are combined with each other. As a result of this, the size can be reduced and high-voltage output can be obtained, without the need for output transformer. Since it is unnecessary to select semiconductor devices constituted in series, gate control is simplified.  Since the circuit voltage is reduced, the reliability of the device is enhanced. The output- side harmonic component can be determined at a PWM switching frequency of the semiconductor devices.

Abstract: This invention relates to a gear shift method for an electric automobile, which is used upon changing a gear ratio of a transmission in the electric automobile. First, in step 1, when a change-over signal is outputted from shifting means, output control of a motor, which has been performed in accordance with a stroke of an accelerator pedal, is canceled, and the transmission is changed into a neutral position. In next step 2, an output amount of the motor is controlled in accordance with a target motor output amount corresponding to a target motor rotation speed, said target motor rotation speed being calculated based on a vehicle speed at a time of the changing operation and a gear ratio of a selected target gear position. Then, in step 3, the transmission is changed into the target gear position. In subsequent step 4, an output of the motor is allowed to gradually return to an output amount corresponding to a stroke of the accelerator pedal. These features make it possible to perform a prompt and smooth change-over of a gear ratio even when the accelerator pedal remains depressed. <IMAGE>

Abstract: Slots of different types are fabricated using a single latent image mask. The slots of different types are thus located with respect to each other in a self-aligned relationship. In one embodiment an oxide of the semiconductor material, e.g., silicon dioxide, is used as a unitary masking layer. The slots of various types are defined in the mask and are fabricated in succession by relying on a universal etch and differential thicknesses for the oxide layers over slots of the different types. When the slots are formed they are filled with a suitable material. In another embodiment at least a dual layer latent image mask is used in which the two materials have different etch properties. One layer is used as a stop etch layer during fabrication of one of the slot types.
