Title: Production of hot-melt conjugate fiber
Inventor: IZUMI TOMOYUKI
IPC: D01D5/34
Filed: 1994-01-25
Abstract: PURPOSE:To provide a process capable of melt-spinning a hot-melt conjugate fiber weldable at low temperature without generating the adhesion between the single filaments in high workability. CONSTITUTION:A core-sheath conjugate fiber containing a polyester A having a crystal melting point of 50-80 deg.C as the sheath component and a polyester B having a crystal melting point of >=200 deg.C as the core component is produced by melt-spinning. In this process, a polyester having a melt-viscosity of 2,500-5,000 poise at the melt-spinning stage is used as the component B and the spun yarn is cooled with a cooling air flow of <=20 deg.C blown against the spun yarn at a position within 25mm from the end row of the orifices bored on the spinneret.

Title: Plasma cutting and heating device
Inventor: SHINADA TSUNEO
IPC: B23K10/00
Filed: 1989-02-03
Abstract: PURPOSE:To simplify the construction of a torch and to facilitate the handling thereof by supplying water to the cooling water path of a nozzle part for ejecting high temp. plasma flow and introducing the steam generated in this cooling water path as a plasma working gas to the upstream of the nozzle. CONSTITUTION:The nozzle 8 which is an anode is rapidly heated by anode descending and arc heat upon arc starting. The water flows from a cooling water inlet 9 into the nozzle 8 when a water valve 2 is opened at the point of the time when the nozzle 8 is sufficiently heated. The water is then heated up to a boiling point in the cooling water path 10 to generate the steam. This steam is emitted from a steam introducing port 11 and is introduced as the plasma working gas through the hole 13 in the tangent direction of a ring 12 for gas whirling to the upstream of the nozzle and is emitted from the nozzle hole 14. The arc generated between an electrode 6 and the nozzle 8 is, therefore, throttled by the steam passing the nozzle hole 14 and is ejected as the high-temp. plasma flow with the steam as the working gas from the nozzle hole 14.

Title: Surface defect inspectng method
Inventor: MISHIMA YUKIHIKO
IPC: G01B11/30
Filed: 1988-02-05
Abstract: PURPOSE:To automatize inspection by comparing the defect density in a specific area with a threshold value. CONSTITUTION:When image information containing defects is inputted, an A/D converter 6 perform proper sampling and binary coding processing. Information on an area set by an area setting part 13 is stored in an image storage part 7. A defect extraction part 8 reads the information out of the storage part 7 and extracts the defects. A defect are calculation part 9 calculates the area of the extracted defects and stores them in an area storage part 10 and stores it in an area storage part 10 and a defect density calculation part 14 adds a calculated value; and a comparison part 11 compares the sum of the calculation part 14 with the specific threshold value and a connection judgement part 16 judges that the specific area connects with the address area of a dummy defect when the sum is larger and transfers it to a comparison part 11. When it is judged that they do not connect, it is transferred to an output part 12 and information showing that there is the defect in the specific area, e.g. NG on a display device. When the sum is smaller than the threshold value, it is judged that the defect connects, the information is transferred to the output part 12, which displays OK showing that there is no defect on the display device, thereby automatizing the surface defect inspection completely.

Title: Fatigue monitor of rotating shaft
Inventor: KUMAZAWA MICHIO
IPC: G01M99/00
Filed: 1978-03-02
Abstract: PURPOSE: To monitor the fatigue of a shaft thereby to prevent the shaft from being broken by monitoring the variation in the torsional intrinsic frequency of the shaft system in terms of reduction of the torsional spring constant of the shaft due to the fatigue and cracking in the shaft.  
     CONSTITUTION: A pulse generator 10 generates pulses of such frequency as is proportional to the r.p.m. of the shaft 4, and a rotational irregularity meter 11 meters the fluctuations in the pulse frequencies to detect the torsional vibrations of the shaft 4. When there arise disturbances in torque such as abrupt short-circuiting, the waveforms of the meter 11 are analyzed by means of a frequency analyzer 12. Then, as shown in solid lines, a peak is found at the torsional intrisic frequency f 1  of the shaft system. Here, the intrinsic frequency is deduced in advance. When the shaft 4 is subjected to fatique or cracking due to a sudden accident, the cross- sectional area of the shaft is reduced so that the torsional spring constant is accordingly decreased to shift the intrinsic frequency f 1  downward to f 2 . Thus, it is judged by a discriminator 14 whether the frequency f 1  is shifted to f 2  or not. If this shift takes place, the result is displayed in a device 15, and an alrm is generated.

Abstract: PROBLEM TO BE SOLVED: To avoid a voltage shortage state caused by the voltage decline of a power supply and maintain stable control, by a method wherein, when the output voltage of a DC power converter is lower than an output voltage set value, a d-axis current is controlled in accordance with a d-axis current command which is corrected by adding a d-axis current command correction signal to it. SOLUTION: When the output voltage Vdc of a DC power converter 108 is lower than an output voltage set value Vdcr, a d-axis current command correction signal Id* is obtained by a voltage controller 125 from a deviation signal between a primary voltage signal V1FB and a primary voltage command value V1*. The d-axis current command correction signal Idx* is added to a d-axis current command Id1* outputted by a dq-axis current command calculator 123 to obtain a d-axis current command Id*, and a d-axis current is controlled in accordance with the d-axis current command Id*.  With this constitution, even if an AC power supply voltage is declined, the d-axis current is applied in accordance with the decline of the DC voltage on the output side of the DC converter of a power conversion unit, and the primary induced voltage of an IPM motor is lowered to avoid a voltage shortage state and stable control can be realized.
