Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain a sample which is changed little in structure by processing even when containing heavy elements partly and has a uniform process face by projecting a focused ion beam parallel to the surface of an object to be processed from a side face of the object to be processed, and forming the sample of a thin film for use in an electron microscope. SOLUTION: A semiconductor sample 15 has projecting parts 16 formed like stairs by a dicing saw 5. The sample is cut by the dicing saw 5 from a point separated by a predetermined distance from an observation part of the projecting part 16 in a direction orthogonal to a sample surface. An unnecessary semiconductor sample 15a is cut off and a focused ion beam(FIB) process face 19 is formed. The FIB process face 19 is marked by a laser or the like to recognize a transmission electron microscope(TEM) thin film sample part 17. The sample is loaded on a stage of an FIB apparatus so that an FIB 10 is irradiated at right angles to the FIB process face 19. While the marking on the FIB process face 19 is confirmed, a process area 18 is cut to leave the TEM thin film sample part 17 formed thin in a uniform thickness as an observation face.

Title: Positioning device for crank shaft
Inventor: MUNEKATA KENICHI
IPC: F16C3/04
Filed: 1978-06-23
Abstract: PURPOSE: To make precise positioning of a crank shaft even if the diameter of a reference hole is dispersed, by eliminating the play between the reference hole and a positioning pin by distributing the play to both sides at the pin center.  
     CONSTITUTION: The second element 33 of a positioning pin 10 is horizontally moved by a plunger 37 due to a force of a spring 38, and a reference hole Wh is positioned concentrically with the center of the pin 10 by pressing the contact points 33a, 33b to the inner surface of the reference hole. When a cylinder 35 is provided with pressure oil, a piston 36 turns the second element 33 rightward to form a clearance between the pin 10 and the hole Wh. Then a shaft ring 19 is activated in this state by means of a cylinder 22 and the positioning pin 10 can be set to the hole Wh. Since the reference hole can always be positioned concentrically to the positioning pin despite the dispersion of the hole, the accuracy of positioning is much improved.

Title: Control method for variable voltage and variable frequency inverter
Inventor: OGAWA SHINICHI
IPC: H02M7/48
Filed: 1979-06-20
Abstract: PURPOSE:To obtain a signal to effectively accelerate an induction motor by passing a signal with a fixed acceleration factor through a function generator which corresponds to necessary acceleration wherein the signal is obtained from the deviation signal of a speed command and a frequency command feed back signal passed through a comparator and an integrator. CONSTITUTION:A speed command signal 1 is compared with the feed back signal of a frequency signal and the magnitude is judged by a comparator 2. As a result, if the frequency signal does not meet the speed command, the frequency is tried to raise with a fixed time constant by an integrator 3. However, the frequency is converted into predetermined acceleration characteristics by a function generator 4. This signal becomes a frequency command signal and is converted into the gate pulse trains of a corresponding frequency through a voltage control frequency oscillator 5 and a ring counter 6. The gate pulse trains are applied to the gate of an inverter 7 to raise the frequency applied to an induction motor 8. Meanwhile, the signal is also fed back to the speed command through a feed back gain 9 to judge whether the signal has been accelerated up to a predetermined frequency.

IPC: G06G7/60
Filed: 1991-04-10
Abstract: PURPOSE:To obtain a digital neural circuit which can perform arithmetic processing at a high speed with a small hardware constitution. CONSTITUTION:When the 1st input signal which is permitted to input by an input control circuit 7 is inputted to a FIFO 5, a selector control line selects a threshold by means of a threshold/subtracted result selector 1 and inputs the selected threshold to a subtracter 3. Then the 1st subtracted result is obtained by inputting the 1st input signal and 1st load to a multiplier 2 from the FIFO 5 and subtracting the multiplied result of the multiplier 2 from the threshold by inputting the multiplied result to the subtracter 3. Thereafter, the subtraction of multiplied results of the input signals and loads read out of the FIFO 5 from the subtracted results selected by the selector 1 is continued. Then, until the MSB of the output of the subtracter 3 is inverted, the 1st output value 61 which is outputted when the threshold is not exceeded is continuously outputted and, after the MSB is inverted, the 2nd output value 62 which is outputted when the threshold is exceeded is continuously outputted.

Filed: 1990-03-27
Abstract: PURPOSE:To remove abnormal microprojections as well by pressing a polishing tape to the surface of a substrate or magnetic disk by the bending rigidity of the polishing tape. CONSTITUTION:The polishing tape of a specified length is passed between two pieces of rolls 2 and is pinched by nip rolls 3. The rolls 2 are rotated to rotate a substrate 5 for a magnetic disk. Working parameters are the grain size of the abrasive grains of the polishing tape, the base film thickness of the tape, the tape length between two sets of the rolls, the rotating speed of the substrate, and polishing time. The polishing of the surface with an extremely light working pressure is possible according to this constitution and the abnormal projections on the surface harmful to the characteristics of the magnetic disk are effectively removed. While the working device is simple in construction, the device is capable of executing the surface polishing with high accuracy.

Title: Unwinding length measuring method for winch cable
Inventor: FUJIWARA YASUHIKO
IPC: B65H61/00
Filed: 1987-03-31
Abstract: PURPOSE:To facilitate correction of a measurement origin, by a method wherein, based on a winding length, by means of a difference between the overall length of a cable and a remaining winding length of a drum prevailing during unwind ing of a cable, the unwinding length of the cable is measured. CONSTITUTION:An observing device 3 is mounted on the tip of a cable 2, having an overall length of, for example, 1000 m, wound around a drum 1. In which case, when a winding length is 500 m, the same 500 m is indicated as an unwind ing length. When the cable 2 is cut by a length of 300 m, even when a winding length is the same 500 m, an unwinding length is 200 m. Thus, by performing measurement by means of a coordinate serving as an origin being a winding length available when development of the cable 2 is maximized, automatic measurement is practicable without measuring the length of a cut cable. This method enables easy correction of a measurement origin without damaging measurement precision even when the tip of the cable is cut.

Title: Method and device for encoding/restoring image data
IPC: H04N19/172
Filed: 1992-03-31
Abstract: PURPOSE:To enhance the efficiency by encoding only an effective block in which there is a variation in the same position of the previous image and the present image and omitting code data in the whole image, and also, to prevent deterioration of the picture quality by deciding it to be a scene change, when the effective block is above a threshold, and encoding the whole image. CONSTITUTION:Image data is written in a buffer 11, and thereafter, sent to a variation deciding part 13 by one block each, compared with a reference image of a reference frame holding part 12, its variation is compared with a threshold of a discriminating threshold holding part 14, and a result of deciding whether it is an effective block or not is inputted to an information holding part 16. Subsequently, only the effective block is encoded by an encoding part 19, and on the other hand, the number of effective blocks of one frame is counted by a counting part 15, and when it exceeds a threshold of a scene change discriminating threshold holding part 17, it is devided to be a scene change frame and all the blocks are changed to the effective blocks and encoded. In such a way, the block which is scarcely varied is not encoded and the efficiency is enhanced, and also, even at the time of scene change, deterioration of the image can be prevented.
