Abstract: PURPOSE: To simplify a breakaway after pressure collapse by providing a fine aperture for flowing air to a hard substrate surface when pressure-collapsing an abnormal projection produced on a semiconductor wafer surface in a process of crystal growth by pressing it down against the hard substrate surface.  
     CONSTITUTION: Wafer 2 which has no abnormal projection on semiconductor- wafer mounting stage 1 is mounted with the projection up. By using driving mechanism 3, stage 1 is raised to push wafer 2 against hard substrate 4, made of sapphire or tungsten, arranged over state 1, thereby collapsing the abnormal projection by pressure. At this time, fine aperture 5 to be opened is provided to the surface of hard substrate 4 and after the pressure collapse, gas is supplied from the pressure feed mechanism connected to it, thereby making wafer 1 break away from hard substrate 4. As a result, trouble that substrate 4 and wafer do not break away keeping contact will not occur and the breakaway is simplified without  damaging wafer 1.

IPC: G06T1/00
Filed: 1991-02-19
Abstract: PURPOSE:To enable the shape, position and attitude of a multiplity of kinds of IC leads to be detected by setting up the range of visual field of a zoom optical system corresponding to the configuration size of an IC. CONSTITUTION:A system controller 8 indicates the optimum visual field set up amount for the lead pin inspection to a zoom optical system 2.

Through these procedures, since proper range of visual field can be set up by the motor-driven zoom optical system 2, such problems as the shifting of the range of visual field by shifting an area sensor and the decline in the resolution due to the detection of needless range of visual field can be settled thereby enabling the bending state of the lead pin to be detected regardless of the IC size.

Title: Speed sensor
Inventor: OWADA MINORU
IPC: G01P3/487
Filed: 1990-02-02
Abstract: PURPOSE:To shorten the delay of speed control and to reduce the cost by producing a magnetic field in the motion direction of a conductive body in motion and detecting variation of the magnetic field with an eddy current generated in the body in motion. CONSTITUTION:The N pole 2 and S pole 3 of a magnet are arranged across the motion space of the conductive body 1 in motion such as a robot arm to produce the magnetic field 4. Magneto-resistance elements 5a and 5b are arranged in the magnetic field 4 to constituted a bridge circuit 6. When the body 1 in motion moves across the magnetic field 4 in a direction X, the eddy current is generated in the body 1 in motion to increase the intensity of the magnetic field 4. At this time, magnetic flux operating on the element 5a is larger in density than magnetic flux operating on the element 5b, so the resistance value R1 of the element 5a becomes larger than the resistance value R2 of the element 5b to generate a speed control signal voltage V corresponding to the speed of the body 1 in motion. Consequently, a speed control signal can be outputted directly with the simple hardware constitution to reduce response delay and to reduce the cost.

Title: Cruise control device
Inventor: SUZUKI NORIO
IPC: F02D29/02
Filed: 1988-02-05
Abstract: PURPOSE:To quickly and smoothly perform the convergence to the target car speed by cutting the D control of the PID control in the feedback correction during the preset time by a timer when the automatic cruise is set. CONSTITUTION:When the automatic cruise is set by a switch 2, a control device 7 initially sets the target throttle opening and drives an actuator 8 in response to the target car speed set by an accelerating switch 3 and a setting switch 4. When the throttle opining detected by a detector 5 reaches the target value, the feedback correction of the target throttle opening is performed by the PID control based on the deviation between the actual car speed detected by a detector 1 and the target car speed. In this case, the D control is cut and the feedback correction by only the P control is performed during the preset time by a timer when the automatic cruise is set. The drop and overshoot of the car speed are prevented from occurring, the convergence to the target car speed can be quickly and smoothly performed.

Title: Synthetic aperture radar
Inventor: MORIMOTO SHIGERU
IPC: G01S13/90
Filed: 1984-02-15
Abstract: PURPOSE:To vary resolution and power consumption characteristics during operation by varying the pulse width or modulation frequency band width of a transmit pulse radio wave sent out of a transmitter. CONSTITUTION:Time-frequency characteristics of linear frequency modulation for obtaining desired resolution or power consumption characteristics by varying the pulse width or modulation frequency band width are so varied by shortening delay time width (t1-t2) to (t1-t3) without varying the modulation frequency band width (f1-f2) in low power mode. On the other hand, (f1-f3) is narrowed down in low resolution mode without varying (t1-t2) to decrease a pulse compression rate. Then the pulse width (t1-t2) and modulation frequency band (f1- f2) are both narrowed down in low power and low resolution mode to (t1-t3) and (f1-f3).

Filed: 1991-01-28
Abstract: PURPOSE:To reduce the using amount of a memory as a frame delay means causing a cost up by making the carrier frequency of a chrominance signal lower to be stored in a frame memory as a frame delay means. CONSTITUTION:A band-pass filter(BPF) 2 takes the only part multiplying luminance and chrominance signals out from an analog composite video signal 1 in a still picture state to be outputted to a frequency conversion part 21. The frequency conversion part 21 converts a band-limited composite video signal 1 into a low-frequency conversion signal having the prescribed carrier to be outputted to a chrominance signal extraction part 22. The chrominance signal extraction part 22 takes out a chrominance signal by subtracting an output signal of the frame memory 11 with this signal delayed by one frame to be outputted to a D/A converter 13. A subtracter 17 subtracts the chrominance signal from a frequency converter 15 from the composite video signal of the delay device 3 and outputs a luminance signal.
