Filed: 1994-09-22
Abstract: PURPOSE: To prevent deterioration of gate breakdown strength due to cleaning before polysilicon deposition and to improve reliability by forming a buried contact hole after forming a first polysilicon film on a gate oxide film and by carrying out the precleaning thereafter. CONSTITUTION: A gate oxide film 22 is covered with a first polysilicon film 23 and it is precleaned in the state.

Abstract: PROBLEM TO BE SOLVED: To prevent breakage on a blade arising from contacting and scattering of corrugated irons when works are executed with a tractor by a method wherein recesses and projections in embossed patterns are provided at the center on the surface of a flat sheet made of soft vinyl chloride or the like. SOLUTION: Recesses and projections 2 in embossed patterns are provided at the center on the surface of a flat sheet 1 made of soft vinyl chloride or the like.

Then, the sheet 1 is put on a levee for reinforcement of the levee and prevention of running of water into a rice paddy. Thereby, slippage can be prevented on walking on the levee while the sheet can be prevented from being slipped. Furthermore, damages can be prevented from occurring to a blade of a tractor even though the blade is brought into contact with the levee while being operated.

Title: Drive circuit of stepping motor
Inventor: MUROFUSHI HARUTOSHI
IPC: H02P8/12
Filed: 1983-12-05
Abstract: PURPOSE:To suppress the brake force cause by counterelectromotive force by absorbing the counterelectromotive force generated in the excited phase only at high speed rotation time by a Zener diode. CONSTITUTION:A series circuit of diodes Da-Dd and a Zener diode ZD is connected in parallel with exciting phases La-Ld of a stepping motor, and a transistor T1 is connected between both terminals of the diode ZD of the series circuit. When the rotating speed of the motor is lower than the predetermined set speed, a transistor T2 is turned ON, and the diode ZD is shortcircuited. When higher than the predetermined set speed, the transistor T2 is turned OFF, and the diode ZD is inserted in series. Thus, the counterelectromotive force is absorbed by the diode ZD, thereby suppressing the brake force to the rotation of the motor.

Title: Method for recognizing position of lead of component and device mounter using the method
Inventor: TOKIMINE TOYOHIKO
IPC: H05K13/04
Filed: 1992-08-27
Abstract: PURPOSE:To recognize the position of leads of a device with high accuracy by calculating an average value as the center of gravity of a lead from the data of positions of the center of gravity of the images formed by slit-beam reflection. CONSTITUTION:Parallel slit beams are projected on a lead R1 of a device Q and the slit beams are reflected from plural and different positions of one lead. The images formed by reflection of these slit beams are picked up. Then, the center of gravity of each slit-beam reflection image is calculated and an average value x10 of x-coordinate values of those calculated values is obtained. When this average value x10 is a distance between a slit-beam projected position of the lead R1, a height position h10 of the lead R1 is worked out by multiplying x10 by tan theta (tantheta is a projection angle of the slit beams). In this way, the height positions are calculated regarding all the device leads and while the results are compared with the data of lead heights of devices which are inputted previously, it is decided whether all the leads are positioned at the height within an allowance or not.

Abstract: PROBLEM TO BE SOLVED: To provide a method for smoothing curve and curved surface having no degradation which can be applied generally to the smoothing processing of the segmented linear approximation of a smooth curve or curved surface by generating a low-pass filter effect which is applied to an arbitrary polygonal curve, polyhedral curved surface, etc., as the function of curvature. SOLUTION: After the set of the vortexes V of an input segmented linear figure 405 is decided, the vicinities of the vortexes are decided with respect to each vortex vi indicating the figure 405 (steps 410 and 420). First and second scale factors having opposite signs, with the negative factors being larger than positive factors, are specified (step 430) and the first and second vector displacement of the vortexes are decided by multiplying mean first and second vectors by the first and second scale factors (steps 440 and 460). Then the positions of the first and second vortexes are decided with respect to all vortexes of the figure 405 (steps 450 and 470) and the present position of each vortex is established as the second position (step 475).  Thereafter, the figure thus obtained is evaluated on the basis of smoothness and, when the figure meets the basis, the figure is outputted as a smoothed figure (steps 480 and 490).

Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To rationally reduce power consumption by supplying power to a reception part after the lapse of the starting period of a reference oscillator when starting receiving operation in a receiver for intermittently performing the receiving operation. SOLUTION: A reception part 1 selects a desired signal out of radio waves coming to an antenna 2, amplifies that signal and demodulates it. With the oscillated output of a reference oscillator 2 as a reference signal, the signal of a desired frequency is generated by a PLL circuit and applied to a mixer circuit, and a reception frequency is determined. In this case, a power source control part 4 supplied power at all the time in active state and controls the supply of power from a battery 5 to the reception part 1 and the reference oscillator 3. Concerning this power control, the power source of the reception part 1 is turned on after the lapse of the starting period from the power source ON of the reference oscillator 3.  In this case, the starting period is defined as the period from the power on of the reference oscillator 3 to the stabilization of its oscillated output, namely, until it becomes a prescribed oscillation level and a prescribed oscillation frequency.
