Title: Black color detector
Inventor: USUI HIROSHI
IPC: G01J3/50
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To easily detect a black target by ORing the output signals of high- and low-sensitivity projection and reflection type photoelectric sensors by means of hardware or software approach by utilizing slight reflected light from the black target. SOLUTION: One of two sets of projector-incorporating reflection type photoelectric sensors 1 is adjusted to high sensitivity so that the sensor 1 can output a signal when a target 6 is black at a required distance and the other sensor 1 is adjusted to low sensitivity so that the sensor 1 cannot output any signal when the target 6 is black at the required distance. When the sensors 1 detect white color, a white color signal is outputted from the sensors 1 by ORing 3 the outputs of the sensors 1, because the outputs are matching. When the sensors 1 detect black color, the high-sensitivity sensor generates an output, but the low-sensitivity sensor does not generate any output. When the outputs of the sensors 1 do not match, a black color signal is outputted from the sensors 1 by ORing 3 the outputs of the sensors 1 by inverting 2 the output of the low-sensitive sensor. When the target 6 is white, the white color signal is outputted to white-only terminal 5 and, when the target 6 is black, the black color signal is outputted to a black-only terminal 4. When both sensors 1 do not output, it is discriminated that no target 6 exists.

IPC: H01L21/60
Filed: 1989-08-31
Abstract: PURPOSE:To decrease an impact load to a large extent by rapidly decreasing the lowering speed of a bonding tool immediately before contact with an inner lead. CONSTITUTION:For example, the lowering speed of a bonding tool having a 50-mm stroke is controlled with pulses at the frequency of 30-40kHz and 4,000 pulses per revolution by using a pulse motor having high resolution. At this time, the bonding tool is lowered at the high speed of 20cm/sec for 49mm of the 50-mm stroke of the bonding tool. The speed is fed back with an encoder, and the number of revolution of the pulse motor is controlled. The bonding tool is lowered at the low speed of 0.5cm/sec for remaining 1mm. Thus the bonding is performed. In this way, impact on the inner lead can be mostly eliminated.

Abstract: PURPOSE:To accelerate the operation of an inverter logic circuit formed of a pnp constant current source transistor and an npn transistor by forming the pnp transistor in a vertical shape. CONSTITUTION:A p-type inject layer 2, a current blocking layer 3, an n-type conductive layer 4 are laminated on an InP substrate 1, Zn is selectively diffused in the layers 3, 4 to form an injector region 14 as p-type.

Since the transistor 121 is of vertical shape, its base width can be reduced by the thickness of the layer to enhance the injection efficiency. When the thickness of the layer 6 is selectively varied, the parasitic resistance of the transistor 122 is reduced as a small emitter resistance. Further, the transistor 121 is formed with a wide gap emitter to enhance the injection efficiency. When the layer 3 is formed with large forbidden band and high resistance, a current leakage is reduced to accelerate the logic operation.
