Abstract: PURPOSE:To obtain a formed picture with high resolution not requiring screen processing by providing plural lasers modulated by plural different multivalued picture signal and plural photosensitive bodies to the device. CONSTITUTION:Setting data 44 from the output port of a microprocessor 74 and a picture signal 43 are inputted to a selector 45. A D/A converter 47 converts the output 46 of the selector 45 into a voltage. A subtractor 48 subtracts the voltage of a laser power detection signal 50 from a voltage of a picture signal 70 and outputs an error signal 49. A D/A converter 68 converts a laser bias current setting data 67 from an output port of the microprocessor 74 into a voltage. A photodiode 69 monitors the laser beam of a laser diode 58 and supplies a current proportional to the laser power. The laser optical output is monitored as above and a monitor signal is fed back to a current flowing to the laser diode.

Title: Manufacture of low carbon steel
Inventor: MATSUO TORU
IPC: C21C5/28
Filed: 1986-02-19
Abstract: PURPOSE:To manufacture a low carbon steel in large quantities at a low cost by blowing iron oxide powder into a molten steel in a converter with a carrier gas after the refining of the molten steel by blowing is finished. CONSTITUTION:When the refining of a molten steel by blowing is finished in a converter, iron oxide powder is blown into the refined molten steel having about 0.03% C content with a carrier gas. The powder is preferably blown from a tuyere for an agitating gas fixed in the bottom of the converter but the powder may be blown from a pipe-shaped lance immersed in the molten steel from the surface of the molten steel. Ar is generally used as the carrier gas but N2 may be used. Iron ore, scale or the like is used as the iron oxide and the particle size is preferably regulated to <=about 250 mesh. Thus, a low carbon steel having <=about 200ppm C content is manufactured in large quantities at a low cost.

Title: Semiconductor device
Inventor: ANDO SHINJI
IPC: H01L21/60
Filed: 1987-02-17
Abstract: PURPOSE:To obtain good bonding strength in wire bonding, by forming a fourth metal layer between a second metal layer and a third metal layer, to which a wire is bonded, so that the fourth layer is tightly contacted with the second and third metal layers. CONSTITUTION:A second metal layer 3 blocks the thermal diffusion of gallium in a semiconductor substrate 1. A wire is bonded to a third metal layer 4. A fourth metal layer 6 is formed between the second metal layer 3 and the third metal layer 4 so that the metal layer 6 is tightly contacted with the metal layers 3 and 4. Since the second metal layer 3 and the third metal layer 4 are tightly contacted and connected, rough irregularities are not formed on the surface of the third metal layer 4 even if heat treatment is performed. Thus the wire bonding can be performed rigidly, and the manufacturing yield rate and the reliability are remarkably improved.

Title: Automatic polarized wave face control circuit
Inventor: ISHIKAWA KENJI
IPC: H04B1/18
Filed: 1987-02-18
Abstract: PURPOSE:To control the received polarization plane by using a polarity inverting circuit to invert an input signal in response to the received polarized face thereby always bringing the input signal in response to the polarization plane of the received wave near the maximum and the minimum level. CONSTITUTION:An input signal 1a in response to the polarization plane of the received wave is inputted to the polarity inversion circuit 1, from which an inverted output signal 1b is obtained. Moreover, since the control signal Ga is at logical H during the sweeping of the received polarized plane, a gate switch G1 is closed and the signal 1b is inputted to a peak hold circuit 2. The circuit 2 holds the maximum level of the signal 1b to output the hold voltage 2b. A latch gate signal generating circuit 3 compares the voltage 2b with the signal 1b, the signal of the coincident period H of the both is outputted as a latch gate signal 3b. The input signal 1a in response to the polarization plane of the received wave has a steep characteristic near the minimum level and even if the pulse noise is superimposed near the minimum level, the gate signal 3b holds logical H up to the nearby point of the maximum level of the inverted voltage 1b.

Title: Rotary substrate treatment device
Inventor: IKEDA MASAHIDE
IPC: H01L21/027
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To provide a rotary substrate treatment device short in the treatment time while having a simple device structure. SOLUTION: When a ring-like magnet 23 ascends, a repulsive force of a magnetic force affecting a permanent magnet 8 integral in a push-up member 10 is increased, and when the repulsive force is presently greater than gravity acting on the push-up member 10, the push-up member 10 starts rotating with a support shaft 7a serving as a rotation shaft and a plate 6 also starts ascending together therewith. When the ring-like magnet 23 further ascends, the push-up member 10 rotates until a position where its vertical member 10b comes into contact with a pin 9a, and the plate 6 ascends to the vicinity of a substrate W. At this time, an ascending position of the plate 6 is restricted by using a bolt 11 so that the plate 6 does not come into contact with a pattern face Wa of the substrate W.  If the ring-like magnet 23 is at a position for ascending, as the ring-like magnet 23 is annular, the repulsive force always affects the permanent magnet 8 during a rotation processing and it is possible to maintain stably the plate 6 at an ascending position.

Title: Wiring pattern of printed board
Inventor: MATSUSHITA HIROSHI
IPC: H05K1/11
Filed: 1989-02-15
Abstract: PURPOSE:To prevent excessive enlargement of a developed region of a molten solder to enable high density mounting and to improve a connection strength by constituting a curved plane of a peripheral edge section of a wiring pattern which is connected to an electrode section of a chip part. CONSTITUTION:A plane of a peripheral edge section of an outside of a wiring pattern 7 is shaped in a curve to make an outer edge section of a developed region of a molten solder 4 in a curved shape. Therefore, even if the shape of an electrode section 2 of a chip part 1 to be used is rectangular, the cooled and hardened solder 4 is developed within a curved range which is restricted by a pattern shape as constituting a fillet shape. Thereby, it is possible to prevent an excessive enlargement of a developed region of the molten solder 4, to enable high density mounting and to improve a connection strength.

Title: Pattern matching method and device thereof
Inventor: NISHIJIMA JUN
IPC: G06K9/62
Filed: 1995-02-23
Abstract: PURPOSE: To accurately evaluate the degree of matching between a pattern to be inspected and a reference pattern. CONSTITUTION: A pattern memory stores a pattern to be inspected which is a binary picture. After correcting a position by a correction part 13 so as to allow a reference pattern to coincide with the position of the pattern to be inspected, unmatching picture elements between the reference pattern and the inspected pattern are extracted by a comparing processing part 14. A multiplier 16 multiplies each picture element extrated by the processing part 14 by an weight coefficient stored in an weight coefficient memory 15 and applies the multiplied result to an operation part 17. The operation part 17 obtains the sum of output values from the multiplier 16 and evaluates the degree of coincidence based upon the sum.

Abstract: PURPOSE:To prevent a stain of recording paper in contact with a nozzle plate caused by the levitation of the recording paper or the fluttering of the trailing end thereof in the vicinity of an ink jet recording head during printing to embody an ideal paper feed state and a high printing quality. CONSTITUTION:An ink jet recorder is provided with a movable paper guide 4 slightly rotated by engaging a main feed roller gear 8 with a slide internal gear 6 by actuating an electromagnetic clutch 7 on a control signal and a paper presser sheet 2 of a sheet-form elastic body attached thereto. During the printing, recording paper 13 is prevented from levitating by the paper presser sheet 2 to be spaced a constant distance from an ink jet recording head 1. When a paper detection sensor 3 detects the trailing end of the paper, the trailing end is fed to the position of the paper presser sheet 2. In a succeeding paper discharge action, the electromagnetic clutch 7 and the paper guide rotating slide internal gear 6 slightly rotate the movable paper guide 4 in conjunction with the discharge action. Therefore, the trailing end of the paper is prevented from flutteringly coming into contact with a nozzle plate.
