  • Patent number: 5417822
    Abstract: A gas or fluid pressure or force sensor is disclosed consisting of a fluid-tight housing containing a supply of electrochemically active gas and an electrolytic membrane disposed to divide the housing into two chambers. The electrolytic membrane has one or more pervious electrodes disposed on each side of and in contact with the membrane. A flexible bellows or diaphragm is disposed to form one wall of the fluid-tight housing and provide the contacting surface for transferring a force or pressure to the sensor. A controller is connected to display measurements and to permit automatic sensor calibration, differential pressure-induced diffusion compensation, temperature compensation and sensor chamber pressure control. The disclosed force sensor is useful for application to robotic manipulators and the basic device is useful for measurement of the gas partial-pressure of a selected gas.

  • Patent number: 5415424
    Abstract: In a breakaway trailer brake activating mechanism mounted on a trailer surge brake actuator, one end of a tension coil spring is attached to the breakaway activating mechanism while the other end of the spring is connected to an intermediate link on a breakaway chain. The connection is such that a surplus, predetermined number of breakaway chain links, forming a slack section of the breakaway chain, are connected between the ends of the spring. The spring prevents the slack section of the breakaway chain connected between the ends of the spring from being pulled tight so as to allow for tow vehicle turns even if the breakway chain is incorrectly secured. Thus, during a sharp turn of the tow vehicle, the spring will allow the reserve links of the slack section of chain to extend but not so far as to cause the trailer brake to be activated.

  • Patent number: 5413610
    Abstract: An artificial hip joint of the type wherein a metal stem is fitted into the tapered hall of a ceramic stem head via a tapered cone in the stem, the hip joint being characterized in that the tapered stem engages the tapered hall in the deeper portion of the tapered hall, whereby the compression strength (fracture load) of the stem head is improved. Deep engagement of the tapered stem within the tapered hall is accomplished by, for example, making the angle of the taper of the tapered cone slightly smaller than that of the tapered stem. Preferably, the angle of taper of the tapered cone is smaller than that of the tapered hall by about 40 minutes or less. In addition, the diameter at the base of the hall is enlarged to form a cavity.

  • Patent number: 5414309
    Abstract: A circuit for applying a direct current to a winding. One end of a primary winding of a transformer is connected to a first transistor via a resistor. The other end of the primary winding is connected to a second transistor. The first and second transistors constitute a current mirror circuit. By by-passing through a capacitor, no alternating current flows in the first transistor. The primary winding of the transformer includes a center tap and an AC/DC superimposed signal is input to the primary winding via the center tap. In the primary winding, DC components flow so as to mutually negate DC-magnetization. As a result, there is no need to provide a gap in a magnetization circuit and the construction of the whole circuit including the transformer can be miniaturized with improved characteristics.

  • Patent number: 5412173
    Abstract: A plasma gun assembly for use in high temperature environments couples electrode and cooling water supplying hoses to a plasma gun via an extension arrangement having a conductive cathode extension tube coaxially disposed within a conductive anode extension tube. The cooling water flows through the hollow interior of the cathode extension tube to the plasma gun, then returns from the plasma gun via a passage formed between the outside of the cathode extension tube and the interior wall of the anode extension tube. In this manner the anode and cathode extension tubes are cooled as well as the plasma gun. Powder and plasma gas are supplied to the plasma gun by water-cooled tube arrangements in which such tubes are surrounded by intermediate and outer tubes forming separate passages. Cooling water is coupled via fittings to flow through the passages formed by the intermediate and outer tubes to provide cooling.

  • Patent number: 5412156
    Abstract: A provisional key is determined on the basis of a relatively small amount of performance information (for instance, information on one chord), while a definite key is determined on the basis of a relatively large amount of performance information (for instance, information on progression of plural chords). If a definite key has been determined, an automatic accompaniment tone is controlled on the basis of the determined definite key, but, if no definite key has been determined, an automatic accompaniment tone is controlled on the basis of the provisional key. The definite key based control is performed in a different manner from the provisional key based control. The definite key based control can achieve control of higher musical quality (for instance, tension notes can be used in a daring manner), but such a daring control is refrained in the provisional key based control.

  • Patent number: 5411720
    Abstract: A solid body having extremely narrow passages formed therein for the separation and conveyance of gases by surface diffusion. Because of the relatively high flow resistance resulting from the extremely small cross sections of the passages, the gas conveyance through the solid body can be performed substantially exclusively by surface diffusion. Only those gas particles which are adsorbed on the solid body or on the wall of the passages will be conveyed through the solid body. The surface diffusion can be controlled by suitable selection of the gas/solid body combination. The diffusion is influenced particularly by the temperature of the solid body. When, in the case of a two-gas mixture, the solid body is heated to a temperature above the desorption temperature of one of the gases and below the desorption temperature of the other gas, only the gas particles of the adsorbed gas are conveyed on the passage walls by surface diffusion.

  • Patent number: 5410101
    Abstract: In construction of a pickup unit used for electroacoustic conversion of various vibrations produced on a string instrument, a piezoelectric assembly clamped between a string holder and a bridge is provided with a dual layer arrangement of piezoelectric elements kept in contact with corresponding positive electrodes. The piezoelectric elements closer to the string holder detect string vibrations and the piezoelectric elements closer to the bridge detects body vibrations of the string instrument so that electric signals from piezoelectric elements of different groups can be tactfully blended together for rich and voluminous generation of musical tones over a wide tone range.

  • Patent number: 5410360
    Abstract: A secondary signal is processed and injected into a primary color video signal. The timing of the subsequent transmission of the secondary signal is controlled by timing signals. The timing signals also control the transmission of a carrier burst prior to the transmission of the secondary data signal. This carrier burst is used by a receiver to synchronize with the transmitter, reduce transmission errors and to indicate that a data transmission is to follow.

  • Patent number: 5410098
    Abstract: An automatic accompaniment apparatus employs a chord designating section, a pattern memory, special operation designating section, a pattern read out section, a note conversion section and a tone generator. The chord designating section designates a root and a type of a chord. The pattern memory stores a performance pattern containing note data which designate tone pitches of musical tones. The pattern read out section sequentially reading out the note data from the pattern memory durring the automatic accompaniment. The note conversion section carrying out a note correction operation corresponding to the type designated by the chord designating section on the note data read out by the pattern read out section when the special operation is not designated. In contrast, the note conversion section outputs the note data read out from the pattern memory when the special operation is designated by the special operation designating section.
