Filed: 1990-08-29
Abstract: PURPOSE:To produce a soft air-hardening seamless steel tube by exerting heating under specific conditions in the course of tube rolling, performing tube rolling, and regulating hardness to a specific value by means of natural cooling. CONSTITUTION:After heating is performed to 650-750 deg.C for >=10min without lowering the temp. down to the martentitic transformation point or below in the course of tube rolling for an air hardening seamless steel tube, tube rolling is done to the desired product dimensions.

Title: Synchronizing clock generating circuit
Inventor: OKIDAKA TAKENORI
IPC: H03K5/00
Filed: 1990-08-28
Abstract: PURPOSE:To obtain high synchronization accuracy without need of a high frequency clock signal by forming the synchronization clock generating circuit with plural delay elements connected in series and successively delaying a reference clock by the delay elements. CONSTITUTION:A reference clock signal S2 is delayed by each prescribed time at AND circuits 10-13 resulting in generating delay clock signals DC0-DC3. On the other hand, even when a trigger input of an asynchronous signal S1 is fluctuated, the state of output signals S20-S23 of flip-flops 20-23 is unchanged and a synchronizing clock signal S3 is outputted in a same timing. That is, the synchronization accuracy is approximated with a delay of the delay clock signals DCO-DC3 being outputs of delay elements (AND circuits) 10-13 connected in series by one stage. That is, the relation of synchronization accuracy  one stage of delay element is realized and it is possible to take a delay of one stage of delay element to be less than 1ns in a semiconductor integrated circuit. Thus, high synchronization is obtained.

Then, a sum consisting of the initial outer diametral dimension P1 stored in a preset memory and the stored value 2M1 taken in the supplemental value storing memory is stored in an offset memory as an offset value OFF1. In the similar way, respective offset values for cutters 152, 153, and 154 are stored in the offset memory. Thus, after the proper offset value for each other is set, each cutter is selectively used for cutting process.

Title: Surface treatment device
Inventor: ONO TETSUO
IPC: H01L21/3065
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To decrease the damages to an element by electronic shading by dividing the amplitude of a high-frequency voltage applied on a sample into the period of the specified low voltage and the period of the specified high voltage and alternately switching the voltage to apply. SOLUTION: With respect to the amplitude Vpp of a ligh-frequency voltage, which is applied as plasma etching, the dielectric breakdown rate has the maximum value. When the Vpp is 20 V or lower and 300 V or higher, the insulation breakdown rate becomes 5% or less, which is the degree not causing problems. When the Vpp is 20 V or lower, however, the acceleration of ions is not sufficient, and the etching speed is slow, or the directivity of the etching is worse. In the meantime, at 300 V or higher, the energy of the ions is too high, and the selecting rate of the etching speed of polysilicon and an oxide film becomes small. Then, the OFF period when the Vpp is 20 V or less and the ON period when the Vpp is 300 V or higher are repeated, and the ion accelerating voltage is applied on a sample.  At the repeating frequency from 100 Hz to 10 kHz, the insulation breakdown rate can be mode 5% or less.

Title: Method for measuring multidirectional distance
Inventor: TANMACHI MASAHIRO
IPC: G01B11/00
Filed: 1985-10-15
Abstract: PURPOSE:To enable the measurement of a multidirectional distance, by allowing luminous flux to be incident on a rotating concave reflective mirror and projecting the reflected luminous flux thereof to matter to be measured and reflecting the reflected luminous flux from said matter by the concave reflective mirror to form an image. CONSTITUTION:The luminous flux emitted from a light source 1 is reflected by a rotary concave reflective mirror 3 through a convex cylindrical lens 2 to be incident on matter 7 to be measured. A part of the reflected luminous flux is returned to the mirror 3 and reflected therefrom to be formed into an image. This image is formed at a position separated from the mirror 3 when the matter 7 is at no great distance and formed at a position close to the mirror when at a long distance. The luminous flux formed into an image in a predetermined part Q is incident on a photoelectric converter element 6 through a convex lens 5. Therefore, an image forming position can be known from the output of the element 6 and the position of the matter 7 from the image forming position can be know. That is, by preliminarily calculating the relation between the image forming position on the element 6 and the distance up to the matter 7, the distance up to the matter 7 can be immediately known as the output of the element 6.
