Abstract: An endless flat band has a spirally placed, straight pulling element in the form of a thread or a wire extending in the direction of movement. A transverse connection is generated by loops and at least partially by a binding agent, wherein at least one spiral of the pulling element is inserted into a tubular fabric in the knitting machine. Because the spiral is inserted already straightened into a right/right transfer construction between loops or loops and tuck loops, it is achieved that a symmetrical fabric is made which increases the service life of the flat band and improves the useful properties.

Abstract: In a method of manufacturing a tunnel erase type combined magnetic head core using a first core member having a predetermined pole height dimension defined by a surface on a magnetic gap formation side and an apex, and a predetermined back height dimension defined by the apex and a bottom of a coil core into which a coil is inserted, and a second core member, the bottom of the coil core of the first core member is used as a back height reference face and the combined magnetic head core is manufactured with the back height reference face as reference, thereby facilitating processing of a surface on the pole height side at intermediate steps, namely, a final contact face with which magnetic recording media are brought into contact. Since the back height reference face is used as reference, when combined core chips are incorporated into sliders to manufacture magnetic heads, the process is not affected by variations in core dimensions.

Abstract: In communication control devices having a DMA transfer function and communication control systems for performing a data transmission between such communication control devices, it is desired to reduce time required for processing. In accordance with the present invention, a transmitted data is written in a receiving side memory by a write instruction from the transmitting side CPU. Alternatively, DMA controllers and receiver side memories are changed from one to another in response to a format representing the transmission information. Alternatively, write addresses in the receiver side memory are changed from one to another depending on the format of transmission information. Alternatively, DMA transfer to a buffer memory is controlled by an address counter. In such a manner, a procedure for transfer of data can be simplified.

Abstract: Tempo information representing a performance tempo set at start of an automatic performance is stored in a first register. A tempo restoration switch is provided for reading out the tempo information from the first register and setting the tempo of the automatic performance by this tempo information. Even when the performance tempo is changed freely during the automatic performance, the tempo at the start of the automatic performance can be restored automatically by operating the tempo restoration switch. Tempo information representing a performance tempo set before start of tempo changing may be stored in a second register. A second tempo restoration switch may be provided for reading out the tempo information from this second register and setting the tempo of the autoamtic performance by this tempo information.

Abstract: A method and apparatus for converting input symbols of a fixed length, to output symbols of a greater fixed length. Input symbols are received one at a time and are clocked into the staging register. When a new input symbol is loaded into the staging register, the contents of the first stage are moved to a second stage of the staging register. The new input symbol is loaded into the cells of the first stage. Multiplexers select the contents of cells of the staging register to form the output symbol. A modulo-x counter counts the incoming input symbols. The output of the counter determines which cells the multiplexer selects. Initially, the first stage of the staging register is preloaded with a predetermined pad symbol, and the modulo-x counter is preset. The first output symbol consists of a number of bits from the pad symbol and those bits of the first input symbol needed to complete the first output symbol.

Abstract: A method and apparatus for determining the size and shape to which a finished lens used to make an eyeglass lens is to be cut. Coordinates which define the outer perimeter of a lens are determined by illuminating either an eyeglass frame or a lens. An image of the shadow of the frame or lens is captured by an imaging device. A first linear polarizing filter is positioned optically between a light source and the membrane. A second linear polarizing filter, oriented at 180.degree. from the first filter, is placed optically between the membrane and the camera. Thus, the first and second polarizing filters allow a high definition image to be attained for substantially transparent plastic. A general purpose computer: (1) identifies the edges of the image so as to define the perimeter; (2) orients the image by identifying an orientation line placed upon a lens, if the image is of a lens which is not within a frame; and (3) measures the distance between lenses if an eyeglass frame is being measured.

Abstract: In a multi-layer wiring structure of an integrated circuit device, occurrence of voids due to electromigration in the vicinity of an interface between upper and lower wiring layers is suppressed. The interface is cleaned in vacuum and grain size of the wiring layers is controlled. After an interlayer insulating film (16) having a connection hole (16A) is formed to cover a first wiring layer (14) of Al or an Al alloy, a second wiring layer (18) of Al or an Al alloy is formed and connected to the first wiring layer through the connection hole. When the second wiring layer is formed, grains (G.sub.2) of the second wiring layer are formed so as to be :respectively continuously adjacent to and substantially equal in size to grains (G.sub.1) of the first wiring layer which appear at the interface.

Abstract: A method for producing electrochemical impedance spectra. Spontaneously occuring coupling current noise between an array of electrodes which may be of substantially the same material is detected. A time domain record of the detected current noise is stored and the time domain record of the detected current noise is transformed to the frequency domain. Spontaneously occurring potential noise between the array of electrodes and a further electrode is detected. A time domain record of the detected potential noise is stored and the time domain record of the detected potential noise is transformed to the frequency domain. The frequency domain current noise and potential noise transformations are then transformed to the impedance domain to produce the required electrochemical impedance spectra.

Abstract: A musical tone control waveform signal generating apparatus is provided in order to generate a musical tone control waveform signal by which a musical tone generated from an electronic musical instrument is to be controlled. The musical tone control waveform signal is varied in its envelop level by each of time-division sections to be passed over a lapse of time. For instance, when a key-depression event is occurred, this musical tone control waveform signal of each time-division section is formed by carrying out a computation by use of parameters which are preset with respect to each section. Preferably, the parameters concern with the variation rate and target level of the musical tone control waveform signal to be formed by each section.

Abstract: The method checks whether a punching tool interferes with a closed line to be processed. Conventionally, line segments of the closed line is arranged in a CAD system in the order of drawing sequence. In this method, however, the line segments are arranged in the line extending order. Specifically, prepared is an interference line retrieval file in which data on line segments constituting the closed line are arranged in the order the line segments continue. Then, based on the data in the interference line retrieval file, it is checked whether or not a tool positioned on an arbitrary line segment interferes with other line segments which extend from the arbitrary line segment in a predetermined range in both forward and reverse directions the closed line extends. The line segments that extend within a predetermined range before and behind the subject line segment can be quickly identified with an easy and simple calculation since the line segments are arranged in the line extending order.
