摘要： An apparatus for driving a semiconductor laser for use in a laser-beam printer, in which a laser beam from the laser is deflected so as to scan a light-sensitive drum and a light-sensitive detector placed in the vicinity of one edge of the drum, comprises a first device for determining the operation level for the laser when it scans the drum to record information thereon, a second device for determining the operation level for the laser when it scans the detector to provide a scanning start pulse signal and a controller for controlling the first and second devices so that they are alternately enabled to determine the intensity of the laser beam depending upon whether the drum or the detector is scanned, whereby the intensity of the laser beam is allowed to be adjusted in accordance with the varying light-sensitivity of the drum without fluctuating the instant of generation of the scanning start pulse signal.

摘要： PROBLEM TO BE SOLVED: To prevent air bubbles from being left behind by providing at least one or more of degassiog holes in the vicinity of an outer circumference of a surface packaged parts packaging part of a printed board of a control board where the printed board is filled with a filler and in the printed board on one surface side of which inserted mold parts are packaged and on the other surface of which surface packaged parts are packaged. SOLUTION: A filter forms an air layer 8 because of the existence of surface packaged parts as an obstruct. The air layer 8 follows a flow of the filler 3 and is pushed out along surface packaged parts 2 to the circumferernce of the parts to produce air bubbles 9. The air bubbles once floating appear on the surface through a degassing hole 6 provided in the vicinity of the circumference outside the packaged parts. Accordingly, the air bubbles 9 are prevented from being left behind. Also for an air layer 7 existent between the surface packaged parts 2 and a front substrate 1 it can be passed through the degassing hole 6 and be floated to the surface of the filler 3. For this, the air layers 7, 8 and the air bubbles 9 disappear until the filler 3 is cured, and hence the air bubbles are effectually prevented from being left behind.

摘要： PROBLEM TO BE SOLVED: To simplify a fetching circuit and highly accurately detect open/close states at a high speed by processing the open/close states of a safety switch to a microcomputer by analog signals. SOLUTION: The signals of the open/close states of the safety switch 8 for interrupting the energizing of a clutch 9 are inputted through a safety switch fetching circuit 11 to the analog terminal of the microcomputer 15 as AC signals as they are. Since comparison with a value set beforehand is performed and the open/close states of the safety switch 8 are judged inside the microcomputer 15, circuit constitution is simplified and accuracy is improved, because a processing is performed by the analog signals. Thus, a circuit for highly accurately fetching the open/close states of the safety switch to the microcomputer at a high speed and at a low cost with less number of circuit parts is provided.

摘要： PURPOSE: To provide an electric washing machine excellent in handling property and having a wide opening section without impairing operability by providing an operation section, an operation side transmission/reception section transmitting/receiving the operation signal, and a power reception section receiving the power from a main body on a cover, and providing a main body side transmission/reception section, a power transmission section, and a controller on the main body side. CONSTITUTION: This electric washing machine is provided with an operation section 10 having a display section indicating at least the operation state, an operation side transmission/ reception section 11 transmitting/receiving the signal with no contact point, and a power reception section 12 receiving the power for the operation section 10 from a main body 1 with no contact point on a cover 5. It is also provided with an operation side transmission/ reception section 11, a main body side transmission section 13 transmitting/receiving the signal, a power transmission section 14 feeding the power to the power reception section 12 with no contact point, and a controller controlling a motor on the main body 1 side. An opening section 4 is not blocked by the operation section 10 while operability is maintained. Since the control signal is transmitted and the power is fed with no contact point, no wire passes through the cover 5, the weight of the cover 5 is not increased, no open circuit occurs at a cover hinge section, and the assembling property is improved.
