Abstract: A BIOS includes a 16-bit interface HDC control routine and an 8-bit interface HDC control routine, and also includes an automatic HDC type determination routine. The 16-bit interface HDC has an inherent I/O address (I/O port), but the 8-bit interface HDC has no inherent I/O address (I/O port). By utilizing this fact, a CPU (1) writes specified data at the I/O address inherent to the 16-bit interface HDC. The CPU (1) then reads out the data from the I/O address, and compares the read data with the written data. If a coincidence is obtained, the CPU (1) determines that the 16-bit interface HDC is used, and sets up a 16-bit interface HDC control routine. On the other hand, if no coin­cidence is obtained, the CPU (1) determines that the 8-bit interface HDC is used, and sets up an 8-bit inter­face HDC control routine.

Abstract: In a known arrangement, the frame rate of a television signal is doubled by using a field store. In a first operating mode, each field of the television signal is entered into the field store in this arrangement and read out twice at twice the frequency. In a second mode, only every second field is entered into the field store and read out four times at twice the frequency. The novel arrangement is intended to be used for switching in a simple manner between the two operating modes. For this purpose, the storage control circuit is supplied via the I<2>C bus of the television receiver with a control signal generated in the operating unit. As an alternative, an identification signal generated in the television transmitter, transmitted in the blanking intervals of the television signal and separated from the television signal in a separating circuit in the television receiver can also be used for switching.

Abstract: For the purpose of optionally making thermal fuses, electrical connections or interruptions, there is applied between two terminals (3, 4) on a substrate (5) a layer (1) and thereabove a layer (2), at least one of the two layers (1, 2) forming an electrically conductive connection between the terminals (3, 4). In this arrangement, it is provided that by comparison with the terminals (3, 4), the layer (1) or (2) has a substantially lower de-alloying resistance than the layer (2) or (1). After heating of the substrate (5) or of the layers (1, 2) to a specific temperature, the layer (1) or (2) is de-alloyed by the layer (2) or (1), the layer (1) being detached from the substrate (5). The remaining layer is subsequently divided in the liquid state by the surface tension into two parts which withdraw in sequence onto the two terminals (3, 4). The connection is thus undone upon overshooting a specific temperature. <IMAGE>

Abstract: The casing of a hearing aid can be acoustically dampened and its receiver is less likely to amplify noise stemming from vibrations of the casing when the casing is lined with a viscoelastic material. The viscoelastic lining can be applied by laying a viscoelastic layer across the rim of the casing and drawing a vacuum at the sound-communicating orifice of the casing until the viscoelastic is drawn tightly against the interior of the casing. A preferred viscoelastic layer has at one surface a substance such as fibers or beads that will form temporary bridges to permit an air to be evacuated between the viscoelastic layer and a casing to which it is applied. When the deposited viscoelastic is tacky at room temperature, the components of the hearing aid can be positioned simply by pressing them into the viscoelastic material, thus making the assembly easier than prior methods of assembling tiny hearing aids.

Abstract: A fluid pressure energy translating device of the sliding vane type comprising a cam ring (13) including an internal contour (30), a rotor (25) having a plurality vanes (36) rotatable therewith and slidable relative thereto in slots (35) in the rotor with one end of each vane engaging the internal contour (30). The rotor (25) and internal contour (30) cooperate to define one or more pumping chambers (31,32) between the periphery of the rotor and the cam contour through which the vanes pass carrying fluid from an inlet port to an outlet port. Two pressure chambers (39,40) are formed for each vane and each vane has two surfaces one in each chamber, both being effective under pressure in the respective chambers to urge the vanes into engagement with the cam. Pressure sensing passages (24) extend from the periphery of the rotor (25) to one of the chambers (40) to provide pressure to the chamber. The end of each vane (36) is tapered with the radially outermost portion of the end extending in a trailing manner and each pressure sensing passage leads the respective vane with respect to the direction of rotation thereby sensing pressure ahead of   each respective vane. The leading passages also provide paths for exhausting the undervane displacement to ensure hydrostatic bias on the vane (36) and cause the vanes to contact the cam contour (30) during the pressure transition and displacement zones.

Abstract: The invention relates to a method wherein it is possible, by digital signal processing taking place in the receiver, to reduce errors caused in a television picture by an in­terlaced transmission standard and a low field frequency. The transmitted interlaced (50 Hz/2:1) signal is converted in the receiver either to a non-interlaced (50 Hz/1:1) signal or to an interlaced (100 Hz/2:1) signal. The higher display frequency transfers the errors to higher frequen­cies, whereupon they no longer disturb the viewer. The conversion takes place by means of a weighted median filter operating in a 3*3 window. In the window, the first line is from the preceding field in the memory and the two others are from the latest received field. The filter interpolates a new dot according to these data. The structure of the filter selects implicitly temporal interpolation in a sta­tionary picture and spatial interpolation for moving ob­jects. By altering the coefficients of the weighted median filter it is possible to optimize the filter to operate either in a moving picture or in a stationary picture. The method can be carried out using a VLSI circuit.

Abstract: A brake pad (64) is located in opposition to the circumferential face of a take-up reel base (15). A brake band (69) is wound around the circumferential face of a supply reel base (14). The brake band (69) has a first end which is fixed, and a second end (69a) which is movable toward the fixed first end. The movable sec­ond end (69a) of the brake band (69) is in contact with a tension lever (65) which is swingable around a shaft (67). When a plurality of coaxial mode-switching cams (32a, 32e, 32g) are rotated to an angular position cor­responding to a mode in which a front loading mechanism (13) should be operated, a pinch lever (48) swingable in accordance with the rotation of these mode-switching cams (32a, 32e, 32g) urges the brake pad (64) and forci­bly presses it against the take-up reel base (15). Simultaneously, a tape-pulling member (39), which pulls the tape (T) out of a tape cassette (C) in a state where reel-engaging holes (55, 56) of the tape cassette (C) are in engagement with the reel shafts (14b, 15b) of the supply and take-up reel bases (14, 15), urges the ten­sion lever (65) such that the movable second end (69a) of the brake band (69) is forcibly pressed toward the fixed first end of the brake band (69).

Abstract: A method of communicating between a primary station 10 and a secondary station 20 wherein variable sized packets of information are transferred asynchronously (or in start/stop mode) between the primary station and the secondary station. A communication control (e.g., "BREAK" in the preferred embodiment) indicates the end of each packet. To permit the high speed transfer of data, the secondary station receives a high-speed clocking signal externally, from the primary in the preferred embodiment. The primary station generates and transmits a sequence number in connection with each packet, and the secondary responds to each packet with a status, but without generating a sequence number of its own or trans­mitting a sequence number. The primary station responds to the lack of a response from the secondary station by resending a transmission, while the secondary station responds to a duplicate trans­mission by ignoring the second transmission, and responds by resending the status from the previous transmission (which may not be the current status). This method using a minimum of overhead insures that the secondary station only proceeds after it has successfully transmitted its last status to the primary, thus guaranteeing that dynamically changing status will not be lost.

Inventor: YONEDA TAKAO
IPC: G05D3/00
Filed: 1990-02-26
Abstract: A synchronous control system for a pair of spindles of a machine tool including a master spindle and a slave spindle. Current positions of the main spindles are detected, and a deviation between the detected current positions is calculated. In case the deviation is within 180 degrees, the current position of one of the main spindles which precedes in the forward direction of rotation is determined as a target position for positioning. In case the deviation is greater than 180 degrees, the detected current position of the master spindle or the slave spindle is offset by an amount equal to an integral number of times 180 degrees so that the deviation between current positions of the main spindles after such offset is within 180 degrees. Then, that one of the current position of the main spindle thus offset and the current position of the other main spindle not offset which precedes in the forward direction of rotation is determined as a common target position for positioning. When a positioning instruction is provided by an operator, the main spindle which follows in the forward direction of rotation is controlled so that the position of rotation of the following main spindle approaches the target position.

Abstract: Transmission images are obtained by radiating X-rays having two different energy levels onto a subject in one direction, and then transformed into logarithmic images, respectively. From these logarithmic images, a contrast ratio due to the two kinds of X-rays having different energies is obtained. From this contrast ratio, the term relating to the thickness of the subject is eliminated, thereby providing information only relating to the quality of the material. By collating the information with the previously measured data of materials, the material of the subject is identified.
