Title: Circuit board inspecting apparatus
Inventor: SUGANUMA HIROTAKA
IPC: H05K13/08
Filed: 1992-07-30
Abstract: PURPOSE:To obtain a circuit board inspecting apparatus which can detect a position of an electronic component in a short time. CONSTITUTION:X-Y coordinates are allocated to pixels of image data of an electronic component C obtained by photographing by a camera, and a midpoint B of a lateral direction of the component C is detected from a change of intensity data of pixels of a Y-axis direction. Further, intensity data of the pixels of an X-ray direction from the midpoint B are sequentially compared to detect coordinates of inner and outer boundary points C1, C2, D1, D2 of an electrode Ca and edge points G1-G4 of a lateral direction to obtain a central point CG of the component C, the point CG is compared with position data stored previously to device propriety of the board. Thus, even if a deviation of a mounting position of the component or an irregularity in size exist, the mounting position can be easily detected. A detecting probability can be enhanced, time required for deciding the mounting state can be deleted, and production efficiency can be improved.

Filed: 1981-12-18
Abstract: A smoke detector contains two radiation transmitters and two radiation receivers. Each of the radiation transmitters emits in a different spectral region, for instance, one emits above and the other one below 600 nm. One part of the radiation of both radiation transmitters is conducted via a measuring path, which is accessible to smoke, to one of the receivers constituting a measuring radiation receiver, and another part of such radiation is conducted via a comparison path, which is not accessible to smoke, to the other of the receivers constituting a comparison radiation receiver. Connected to both radiation receivers is an evaluation circuit which forms from the measuring radiation intensities prevailing in the two spectral regions and from the comparison radiation intensities prevailing in the same spectral regions a function of the type:   <IMAGE>    By suitably adjusting or selecting the components of the evaluation circuit, the coefficients a and b are selected such that in the absence of smoke in the measuring path, A becomes zero and in the presence of smoke such is proportional to the smoke density.

Title: Tape counter
Inventor: YOSHIHARA YOSHIAKI
IPC: G11B27/17
Filed: 1982-11-19
Abstract: PURPOSE:To count accurately the travelled distance of a tape by counting the number of revolutions of a pinch roll. CONSTITUTION:Both a capstan 7 and a pinch roll 8 rotate toward arrows respectively to drive a tape 6 toward an arrow mark. The roll 8 turns as the tape 6 travels. The number of revolutions of the roll 8 is counted by a counter 12 after detecting with an optical detector 11 the light sent from a light soure 10 and reflected in a pulse form by a light reflecting material 9. Now it is supposed that (n) units of stripes exist on the outer circumference of the roll 8 and the counter 12 counts (m) units of pulses. In such a case, it is decided that the roll 8 had revolutions of m/n times. The roll 8 is usually made of a light material like rubber, etc. and has a small diameter. Therefore the roll 8 does not continue its revolution by the inertia when it is separated from the capstan 7 or the tape 6, and the number of revolutions is not counted.

Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To perform inverter control at low cost by outputting output data determined by operation, after converting it on a data table of a program ROM which is built in a microcomputer. SOLUTION: An Ac commercial power source 101 is full-wave rectified by a diode bridge 102. A parallel-connected resonance capacitor 103 and a heating coil 104 are connected, and an IGBT 105 is connected in series to constitute a basic circuit of an inverter. A micro-computer 110 outputs data through an output port A112 formed of six or more output ports put in action by a built-in program ROM 111. Data which are digital-analog converted by a D/A output circuit 108 is compared with the output of a reference oscillating circuit 109 via a comparing circuit 107, and switching time is determined on the basis of the output of the comparison circuit 107. The IGBT 105 is then switched on the basis of the output of a gate circuit 106. Software can therefore be constituted in a simple way.
