IPC: G01N29/30
Filed: 1987-04-17
Abstract: PURPOSE:To detect corrosion automatically without being affected by the surface roughness and curvature of a cylinder by correcting the sensitivity of the echo intensity of a main probe which is obtained in the 3rd turn of a cylinder with the received wave of an auxiliary probe which is obtained in the 2nd turn of the cylinder.

Title: Patterning method of semiconductor
Inventor: SAKURAI HIROMI
IPC: H01L21/265
Filed: 1984-05-09
Abstract: PURPOSE:To enable patterning not causing pinholes and to form a vertical pattern accurately by a method wherein a focused ion beam of oxygen is implanted in small depth in the whole of a region corresponding to a pattern information and in large depth in the peripheral edge portion thereof so as to form an oxidized layer and thereafter selective etching is applied by using an etching solution having a large etching selection ratio. CONSTITUTION:A focused ion beam of oxygen is implanted only in a desired area at a desired position on the surface of an Si substrate 1 with an implanting energy of about 50KeV according to a pattern program. By subjecting this substrate 1 to heat treatment in an inactive gas, implanted layers 3 and 3' turn to be an SiO2 layer 4. Next, when the Si substrate 1 is etched by using anisotropic dry etching, etching of Si alone proceeds, and thus it becomes possible to proceed with digging vertically without attacking the SiO2 layer 4 formed deep in the longitudinal direction. On the occasion, the purpose is attaind by any etching method on condition that the etching method applied has a large etching selection ratio between Si and SiO2. When the etching selection ratio between Si and SiO2 is somewhat inferior, on the other hand, the same effect can be produced by enlarging the radius of the ion beam so that the thickness of the oxidized film can be increased to some degree. Then, lastly, the oxidized film layer 4 is removed.

IPC: G01R19/165
Filed: 1981-06-18
Abstract: PURPOSE:To improve the reliability of a voltage check by stopping the feeding of electricity to a load when a battery voltage drops down below a prescribed value. CONSTITUTION:For a battery check, switches 18 and 19 are turned on and a transistor TR4 turns on to power up a control circuit 10. Then, the control circuit 10 turns on a TR14 to feed electricity to an electromagnet for shutter driving in a short time. The voltage drop of a battery 2 by this feeding is compared with the reference voltage of a constant voltage part 36 and when the voltage drop exceeds the reference voltage, an alarm 28 is put in operation. When it is lower than the reference voltage, on the other hand, the sounding of the alarm 28 is stopped to let a photographer know a deficiency in the voltage of the battery, and the electromagnet 12 is powered down. Thus, the intermittent sounding of the alarm 28 when the voltage of the battery 2 is close to a discrimination level is prevent and the reliability of the voltage check is improved.

IPC: D05B45/00
Filed: 1990-04-12
Abstract: PURPOSE:To prevent uneven stitches even when a sewing machine is operated an any rotating speed or even when the rotating seed is sharply changed from a high speed to a low speed, by a method wherein a device is provided to detect the decrease amount of rotating speed of the sewing machine, and when the decrease amount exceeds a specified value, the feed rate of needle thread is corrected so as to reduce the feed rate of needle thread. CONSTITUTION:A CPU 40 takes in needle position signals 42 according to the sewing action of a sewing machine, and calculates the speed of the sewing machine by time measuring of needle position signals, and a needle thread feeder feeds needle thread corresponding to the calculated result. By comparing the present sewing machine speed with the speed one cycle before, it is judged whether or not the speed is sharply changed to a low speed. When it is not a sharp speed reduction, needle thread is fed at a normal rate, and when it is a sharp reduction, the needle thread feed rate is corrected. Thereby, in the case of a sharp speed reduction, the needle thread feed rate is corrected to a lower one, so that uneven stitches due to a sharp speed reduction are avoided.
