Title: Production of sector type steel plate
Inventor: HASUO YASUHIRO
IPC: B21B1/38
Filed: 1981-03-23
Abstract: PURPOSE:To produce sector type steel plates with good yield by rolling a rolling material having tapers down to prescribed thickness from the direction of 90 deg.. CONSTITUTION:In the production of sector type steel plates of designated sizes of short arc length l2, camber quantity (c), thickness (t) and width (w), the geometrically long arc length l1 is determined. Thence, the relations of the W, T1, T2 and l1, l2, w of a rolling steel material having tapers is determined from the equality in the areas of shaded parts. Further, the sizes L, T, W of an ingot which is a raw material are determined from the invariability in weight. The ingot having the above-mentioned sizes L, T, W is produced by blooming, and the bloom is heated in a heating furnace, after which it is formed to a rolling material having a T1>T2 taper by forming and rolling of gradually increasing drafts. This is rotated 90 deg. with a turntable and is subjected to finish rolling down to the final thickness (t), whereby the sector steel plate of a desired size is produced.

Title: Device for monitoring laser beam in laser beam machine
Inventor: HORIUCHI NAOYA
IPC: B23K26/00
Filed: 1994-03-14
Abstract: PURPOSE:To detect the optical axis and the intensity of the output of the laser beam with excellent precision. CONSTITUTION:A diffraction grating bender mirror 11 reflects most of the laser beam B to a converging lens 4, and diffracts a part of the laser beam to the different position from that for the reflected laser beam (the machining beam) Ba. The diffracted beam (monitoring beam) Bb is reflected by a reflecting mirror 18, and guided to a detector 23 through an aperture 21 and a band pass filter 22. The detector 23 detects the position of the coordinates of the monitoring beam Bb and outputs the detected value to a control device 25. The control device 25 controls monitors 15, 16 so that the position of the coordinate of the monitoring beam Bb may be the reference position, and adjusts the position of the diffraction grating bender mirror 11 to align the optical axis of the machining beam Ba to the center of the converging lens 4. The detector 23 also detects the intensity of the output of the machining beam. The stability to the mode change is excellent because the diffracted beam is used as the monitoring beam, and the optical axis and the intensity of the output of the machining beam can be detected with excellent precision.

Title: Method for detecting plugless rolling condition in piercer
Inventor: KOMINE ISAMU
IPC: B21B37/00
Filed: 1984-03-08
Abstract: PURPOSE:To detect a plugless rolling condition in a piercer by fetching the image of the shell of a pipe stock delivered from a piercer into a sensor and computing a measuring value corresponding to the outer diameter of pipe stock for comparing the computed value with a set value. CONSTITUTION:The image of the shell 3b of a pipe stock 3 delivered from the piercing rolls 2, 2 of a piercer 1 is fetched into an image sensor 7a through the lens 7b of a linear ray camera 7. The image is converted into an electric signal, which is outputted, as a timing signal, in sequence at every fixed time. A controller 8 compares the number (n1) of voltage-pulse (measured value) outputted from the sensor 7a with the number (n0) of previously set pulses (set value), to output an alarm signal to an alarm 9 when n1<n0. The alarm 9 is actuated by the signal to output an alarm through light or sounds, etc. Accordingly, the piercer 1 is stopped at once when a plugless rolling condition is informed.

Title: Gas sensor
Inventor: NAKANO TOMOYASU
IPC: G01N27/12
Filed: 1986-02-28
Abstract: PURPOSE:To obtain an inexpensive sensor with simple structure by forming electrodes at part of the surface of the porous silicon substrate on one surface of a single-crystal silicon substrate and on the reverse surface of the single- crystal silicon substrate. CONSTITUTION:The porous silicon layer 14 is formed on one surface of the single-crystal silicon substrate 10, an electrode 12 is formed at part of the surface, and a lead wire 13 is connected. An electrode 14, on the other hand, is formed over the entire reverse surface of the substrate 10 in contact. The silicon layer 11 is formed by treating the top surface of the substrate 10 by anode formation. The lead wire 13 is soldered to the electrode 12, but a material constituting solder is diffused in or penetrates the silicon layer 11 in this heat treatment to change the electric properties of the silicon layer 11. Porous silicon is normal high in resistance, so the silicon is advantages in view of a decrease in resistance by the material. As the area of the electrode 12 formed on the silicon layer 11 is smaller and smaller, it is more and more advantageous in reaction and restoration time. Thus, the inexpensive sensor of simple structure is obtained.

Title: Stopper for resilient liquid sealed bush
Inventor: YOKOTA MOTOYUKI
IPC: F16F13/14
Filed: 1988-02-25
Abstract: PURPOSE:To reduce the size by constructing a stopper device with a stopper placed at a predetermined height between inner and outer tubes at the outside of a liquid chamber. CONSTITUTION:An outer tube 2 is secured to a securing member while an inner tube 1 is fixed with a member to be supported (vibration member) thus supporting the member to be supported resiliently. Since liquid chambers 5 are communicated through a communication path 9, liquid 4 moves and vibration is damped through the flow resistance thereof. A movable valve 11 provided with the communication mechanism 9 has the shape as shown on the drawing, where dynamic spring constant is lowered for faint vibration to improve vibration absorbing performance and exhibit high damping performance for relatively strong vibration. When some impact is applied onto a member to be supported and the inner tube 1 displaces excessively, it may collide against the outer tube 2 with considerable impact to cause breakdown. In order to prevent breakdown, a stopper device 14 is constructed with a stopper 15 placed between the inner and outer tubes 1, 2 upto a predetermined height, and the stopper device 14 is arranged at the outside of the liquid chamber 5. By such arrangement, the volume of the liquid chamber 5 is ensured sufficiently and the damping performance is not damaged. In other words, the size of a liquid sealed resilient bush can be reduced.
