Abstract:
A bipolar cutter/coagulator produces a coagulating waveform comprising an aperiodic sequence of damped RF bursts. The inter-burst spacing is pseudo-random, and the intra-burst RF frequency is swept between preset limits. The burst envelopes are uniform, always starting at the same preselected amplitude.
Abstract:
A computer sewing machine having a plurality of sewing related operating functions and including voice generating components driven by a drive signal and producing voice information concerning various information items including at least malfunctioning and their explanations and handling and their explanations for the sewing machine, process designation input components for producing signals for starting the process of the information items produced from the voice generating means, response input components including at least two switches selectively operated to produce signals to affirm or negate the information items produced by the voice generating components, reception/discrimination components for receiving the signals from the process designation input components and from the response input components to discriminate the designation of the information items, a stitch control device, malfunction diagnosing components for diagnosing malfunctions of the sewing machine on the basis of control operation of the stitch control device to produce signals indicating a malfunction of the sewing machine, specifying components for receiving the signals from the malfunction diagnosing components and from the reception/discrimination components to specify the information items, a language signal storing memory containing language signals, and language synthesizing components operated by the signal from the specifying components.
Abstract:
The invention is to provide an electronic sewing machine which is improved in operation by incorporating lighting indication and vocal instrumentalities for making the operation instruction recognizable during operation of the sewing machine and giving parameters of operating instruction in accordance with issued voice, instead of depending upon electronic memories which store many kinds of patterns for lighting indication of required function.
Abstract:
A control circuit is disclosed for appliances such as dishwashers and clothes washers. The control circuit employs a microprocessor programmed to respond to user selected options to determine the operating sequence of the appliance. Feedback systems permit the detection and indication of fault conditions, such as overfill or drain blockage, and initiate protective responses from the microprocessor to prevent flooding or damage to the appliance. The circuit includes a diagnostic system having a diagnostic routine which will sequence through the usual operating cycles in response to operator input and which may be advanced through the cycles at the operator's discretion. The operative cycles and applicance malfunctions, if any, are displayed on a control panel as the diagnostic routine is executed thereby facilitating diagnosis and repair.
