  • Patent number: 9112622
    Abstract: User is allowed to designate a desired mode defining the respective numbers of channels and mixing buses, and processing for mixing input signals of the number of channels corresponding to the designated mode is performed repetitively to generate signals for the individual buses. The time of arrival of the last step in the mixing processing for the number of channels, corresponding to the designated mode, is detected to output an accumulation result obtained at the last step, and new accumulation is started with a digital audio signal inputted at a step following the last step. Digital audio signals processed by a first signal processing circuit are stored into a memory and transmitted to a second signal processing circuit via a cascade-connection. The second signal processing circuit adds the audio signal, processed for each of the steps, to audio signals input via the cascade-connection and writes added signal into the memory.

  • Patent number: 7420115
    Abstract: In an access controller provided for a musical sound signal generating system, a signal generating section operates when a readout of wave data of one block stored in a working memory is completed in a sound channel, for supplying a next waveform request signal to a CPU, which requests a next block of the wave data for the sound channel. First and second buffer memories are connected between a recording medium and the working memory respectively through first and second buses which are independent from each other. A first transmitting section operates when receiving block specifying information from the CPU, which specifies a block to be read next from the recording medium, for transmitting the wave data of the specified block to either of the first or second buffer memory while reading the specified block of the wave data from the recording medium.

  • Patent number: 5198192
    Abstract: A urine detection device is disposed to a urine receiving surface of a toilet stool in which urine, diluting water and reagent are mixed by vertically moving a piston in the cylinder of the detection device, the reaction between them is detected by an electrode and the ingredient in urine is detected. Liquid in the cylinder is stirred by a stirring device to blown air into the reagent reservoir, by which oxygen is dissolved in the reagent. Cleaning liquid is sprayed from the nozzle to the electrode for flushing. An opening is disposed to a supporting wall of the toilet stool, through which the cylinder is detached or attached. The electrode is disposed such that its rear end is directed to the opening and detached or attached through the opening.

  • Patent number: 5124934
    Abstract: A constant liquid feeding device of the invention comprises a flow meter for measuring quantity of liquid flowing through a pipe, a valve attached to the pipe, a valve control device attached to the valve for opening and closing the pipe, an operating device having a feeding switch and a learning switch, and a control unit electrically connected to the operating device and the valve control device. The control unit is provided with a first memory, a second memory and a comparing device for comparing data stored in the first and second memories. When the learning switch is actuated, the control unit operates to memorize an amount of liquid flowing through the flow meter in the first memory, wherein the amount of liquid is manually controlled by the valve control device. When the learning switch is not actuated, the control unit checks if the feeding switch is turned on.

  • Patent number: 5119829
    Abstract: An apparatus for examining urine for certain constituents thereof includes a vertically disposed cylinder for receiving urine therein. The cylinder includes a diametrically enlarged upper portion having an inside diameter which is larger than that of its remaining portion. A piston is vertically movably disposed in the cylinder. If the piston is lowered, urine can be stored in the cylinder. If it is raised, the urine is discharged from the cylinder, except that only a small portion thereof remains in a clearance defined between the piston and the diametrically enlarged portion of the cylinder. If the piston is lowered again, a reagent and water are supplied into the cylinder and mixed with the urine remaining therein. An electrode is connected to the cylinder for determining the concentration of sugar, etc. in the urine which has been mixed with the reagent and water.
