  • Patent number: 5584681
    Abstract: Disclosed is a gas lighter easy to use, capable of stably maintaining a diffusion flame allowing a visual confirmation of the combustion condition and criticality, irrespective of use in the place influenced by the wind or the like. Further provided is a gas lighter capable of externally performing a fuel gas flow control with ease to maintain a combustion balance between a premix flame and a diffusion flame. The fuel gas stored within the fuel tank is distributed for ejection to form a premix flame and a diffusion flame burning together with the premix flame. A flame hole for premix flame is juxtaposed with a nozzle hole for fuel gas to generate the diffusion flame. An externally operable fuel gas flow control mechanism is provided in a fuel gas flow passage for producing the diffusion flame. A combustion flame of the gas mixture is produced downstream of a catalytic member.

  • Patent number: 5550726
    Abstract: A radio wave signal is transmitted from a radio wave transmitter according to a command from a central control unit, and a supersonic wave is transmitted from a supersonic wave transmitter held by a moving object according to this radio wave signal. A time counter in a supersonic wave detecting device determines the time required from the transmission of the radio wave signal to the detection of the supersonic wave. A coordinate position of the object is calculated on the basis of the thus-obtained time data from a plurality of the supersonic wave detecting devices and positional data of the supersonic wave detecting devices to control the lighting direction of a lighting projector according to a command signal from the central control unit referring to a positional data of the lighting projector.

  • Patent number: 5530325
    Abstract: A control circuit is proposed, which can be used for the phase-shift control of an electric motor in an a.c. voltage supply line. The ground connector of the control circuit, together with the cathode of a semiconductor switch (triac), is directly connected with load current circuit. Because of this, it is possible to do without potential-separating means when it is intended to feed signals at the load current circuit directly into the control circuit. An auxiliary voltage source is connected between the synchronization input and the ground connector to maintain the function of the synchronization input.

  • Patent number: 5502432
    Abstract: A warning apparatus for warning of possible rear-end collision of a given vehicle having the warning apparatus with another vehicle preceding the given vehicle includes: a computer; a distance sensor for measuring a vehicle-to-vehicle distance to the another preceding vehicle; and a velocity sensor for measuring the velocity of the given vehicle. The computer computes a relative velocity of the given and the another preceding vehicle from a differential of the vehicle-to-vehicle distance and then computes an anticipated rear-end collision time by dividing of the vehicle-to-vehicle distance by the relative velocity of the given vehicle. The computer corrects the anticipated rear-end collision time in response to an acceleration and the relative velocity. The computer produces a warning of signal and an alarm is provided in response to the corrected anticipated rear-end collision time.

  • Patent number: 5499247
    Abstract: A multiplex transmission system includes a plurality of multiplex nodes interconnected by a common multiplex transmission line. Data frames are transmitted among the multiplex nodes through the multiplex transmission line. A data frame transmitted from a sending multiplex node includes a data area which is divided into subdivided areas in accordance with data transmitted therefrom and data transmitted from receiving multiplex nodes which send data in response to a send request, in accordance with the number of data pieces or the number of bits, and the receiving nodes send data to respective subdivided areas in a predetermined order, to thereby carry out a data transmission. Accordingly, the sending multiplex node can simultaneously collect data from the receiving multiplex nodes which are functionally subordinate. When any of the receiving multiplex nodes fails to return an ACK signal, the sending multiplex node retransmits the data frame.

  • Patent number: 5469159
    Abstract: A method of detecting the status of a keyboard switch device judges validity or invalidity of the status of switching elements on the basis of simple conditions. With this method, processing of output data is facilitated. In a step S1, a scanning operation is carried out to detect the status of each switching element. In a step S2, the result of the scanning operation is stored in a memory unit as memorized information. In a step S3, closed element total number N, a closed row total number Nr, and a closed column total number Nc are counted with reference to the memorized information. In a step S4, a judgement is made as regards whether or not a predetermined condition is satisfied by the closed element total number N, the closed row total number Nr, and the closed column total number Nc. When the predetermined condition is satisfied, the memorized information is provided as valid data in a step S5.

  • Patent number: 5453568
    Abstract: An indication or image on a display unit is switched in response to changes in performance data of a tune which is being played automatically. Tone pitch data included in the performance data are detected, and the indication on the display unit is switched in response to changes in the detected tone pitch data. Velocity data and tone color data in the performance data may be used in place of the tone pitch data. If a tune is automatically played based on a plurality of performance data which are simultaneously read out, the indication on the display unit is switched based on changes in either of the plurality of performance data. If switching data representing changes of rhythm of the tune is included in the performance data, the switching data are detected, and are used to change a way of switching the indication (image) on the display unit. The indication or image on the display unit may be switched at timings based on beats or strong beats or at timings of measures.
