  • Publication number: 20230304203
    Abstract: A sewing machine includes a sewing unit including a sewing machine motor, a single terminal for connecting a foot controller to the sewing machine, and a controller that controls the sewing unit. When the foot controller is not connected to the sewing machine, the single terminal allows connection of an external device to the sewing machine. The controller performs: a speed-data receiving operation to receive speed data from the foot controller connected to the sewing machine via the single terminal for controlling a sewing speed; a speed-control operation to control the sewing machine motor in accordance with the speed data received in the speed-data receiving operation; an input-data receiving operation to receive input data from the external device connected to the sewing machine via the single terminal; and a data-outputting operation to output output data to the external device via the single terminal.

  • Publication number: 20230170718
    Abstract: A power receiving device includes a storage and a computer. The computer stores a first operating condition indicating a past operating condition of the power receiving device in the storage. The computer detects a power supplying capacity within which a power supplying device can supply power and identifies a specific value in relation to the first operating condition from the storage. The computer sets an incoming power based on both the detected power supplying capacity and the identified specific value, thereby allowing the power supplying device to send the set incoming power.

  • Patent number: 10734895
    Abstract: A power source circuit includes a first converter, a second converter, a switch and a controller. The switch is configured to switch between a first state and a second state, in which in the first state, a first voltage is not supplied to the second converter whereas in the second state, the first voltage is supplied to the second converter. The controller controls the switch to change the first state to the second state in response to detection of the change in a first current flowing in a first load. The second converter is configured to convert a battery voltage of a battery to a second voltage lower than the battery voltage when the switch switches to the first state and convert the first voltage to the second voltage lower than the first voltage when the switch switches to the second state.

  • Patent number: 10490419
    Abstract: In manufacturing a trench type MOSFET, reliability of a semiconductor device is prevented from being degraded due to a short circuit or lowering of withstand voltage between a trench gate electrode and a source region. To achieve the above, poly-silicon films are formed inside a trench in a main surface of a semiconductor substrate and over the semiconductor substrate. Further, phosphorus is thermally diffused into each poly-silicon film from a phosphorous film over an upper surface of the poly-silicon film. Still further, a silicon oxide film formed in a surface layer of the poly-silicon film by the thermal diffusion process is removed by a first dry etching process using a fluorocarbon gas or a hydroxy-fluorocarbon gas. Then, by performing a second dry etching process using a Cl2 gas etc., an insulating film is exposed and, thereby, a trench gate electrode including the poly-silicon film is formed.

  • Patent number: 7228049
    Abstract: A technique for manufacturing optical fixed attenuators in which two fibers are axially cojoined using fusion splicing. The spliced fibers are then captured in either a splice protection splint or cylindrical ferrule that can be housed in an optical adapter. In this process for producing the attenuator, the fusion splicing is preceded by a deformation of the mode field diameters of the ends of the fibers with the cleaning arc function of the splicing unit. The resulting attenuation of the splice is dependent on the amount of deformation of the fiber core and mode field diameter. Such a technique enables precision attenuation with very low wavelength dependent loss to be fabricated. The performance of Dense Wavelength Division Multiplexing systems, as well as test facilities and individual optical components can be improved by the use of such attenuators.
