Title: Automatic wire bonding method
Inventor: TANAKA MASATOSHI
IPC: H01L21/60
Filed: 1982-03-08
Abstract: PURPOSE:To reduce the manufacturing cost of an automatic wire bonding method by recognizing via a TV camera a mark formed of resistance paste to notify the position of an electrode indirectly on a substrate, and calculating the relative position with the electrode on an IC chip, thereby automatically wiring between the electrodes. CONSTITUTION:The position of an electrode on a thick film printed board and the relative position of a position detecting mark (resistance pattern) are accurately decided in advance, and stored. Accordingly, when a position detecting mark is recognized by a TV camera, the presence of the electrode on the board can be discriminated at the position of the prescribed distance from the mark as an origin. The relative position can be calculated by a computer on the basis of the memory. On the other hand, the electrode of IC side can be readily recognized by the camera since Au or Al is deposited at the periphery of the IC chip. Thus, the electrode on the chip and the position detecting mark made of the resistance pattern on the board can be read by the camera, thereby automatically wiring between the electrodes which are recognized at the relative position. The error of matching the mask at the time of forming the position detecting mark and the electrode on the board is slight, and not defective.

Title: Half tone picture forming method
Inventor: SUZUKI YUZURU
IPC: H04N1/40
Filed: 1987-02-19
Abstract: PURPOSE:To form a half tone picture without a deterioration in gradation reproducibility even by using a small matrix by correcting the variable density value of a picture element at a current scanning position according to the weighted averaged value of an error between the variable density value of an input and the variable density value of an output. CONSTITUTION:The variable density value of data from a picture input device 1 or a picture memory 2 is converted to the area of the picture element by a picture processor 3. The error between the variable density value of the input and the variable density value of the output is operated for every picture element of an input picture and this error is stored in an error buffer disposed in the picture buffer processor 3. The error of the three picture elements in the vicinity of the two dimension of a scanning picture element is multiplied by a weight coefficient and summed up and it is defined to be the quantity of ER of the error to be corrected by the scanning picture. Then, the quantity ER of the error is subtracted from the variable density value of the current scanning picture element to obtain the final variable density value after the correction, this final variable density value is compared with a preset threshold matrix to obtain an output pattern. Thereby, the half tone picture in which the error as the average is corrected can be obtained.

Title: Correction of detection angle for pendulum type inclinometer
Inventor: TANNO TOMIYA
IPC: G01C9/12
Filed: 1984-02-29
Abstract: PURPOSE:To obtain accurate angle of inclination of a vehicle by determining the angle of the swing of a pendulum based on the detection angle of a pendulum type inclinometer and the acceleration of the vehicle. CONSTITUTION:A pendulum type inclinometer 10 outputs a signal indicating the detection angle to an adder 11 and a cosine generator 12 and the generator 12 outputs an input signal to a multiplier 13. On the other hand, a rotational speed signal detected with right and left motor rotation sensors 14 and 15 for the vehicle is inputted into the multiplier 13 after an acceleration is multiplied by the mass of a pendulum through a mean value circuit 16 and a differentiator 17 and the multiplier 13 multiplies two forces to input the results into an adder 18. A multiplier 19 applies a signal corresponding to a damped force while a sine generator 20 inputs a signal corresponding to a return force to the adder 18. Then, the adder 18 adds up three input signals and inputs a signal corresponding to an inertial force into an integrator 21, which applies a signal corresponding to an angular velocity to an integrator 24 to output a signal corresponding to the angle of the swing from the integrator 24. Then, the signal is applied to the adder 11, where a signal indicating an output angle from the inclinometer 10 is added thereto thereby enabling the determination of a correct angle of inclination of the vehicle.
