Abstract: PURPOSE: To easily manufacture a nozzle blade with a high cooling effect by longitudinally splitting the nozzle blade with a handle into two parts, one including a hollow space occupied by a cooler core a and the other provided with a handle independently formed by casting, and finally coupling them together by electronic beams.  
     CONSTITUTION: This nozzle blade with a handle consists of a major body 1 of the nozzle blade into which air for cooling the nozzle blade is carried in and the handle 2 which is provided on one end of the major body 1. They are independently formed by precise casting. The major body 1 is hollow, provided with an opening at the top on which the handle 2 is to be put for closing and a coolling air intake port 8 at the bottom. A cooler core 11 through which many cooling air through-holes 10 are made is inserted in the hollow space 9 and a joint face 12 between the handle 2 and the major body 1 of the nozzle blade is machined in the form of a spigot. After the cooler core 11 is inserted in the hollow space 9, the major body 1 and the handle 2 are fit and joined into one by conducting electronic beam welding throughout the peripheral rim of the blade.

Title: Leakage detector
Inventor: USAMI TAMOTSU
IPC: G01M3/20
Filed: 1981-02-20
Abstract: PURPOSE:To perform leakage tests of products to be teated automatically and efficiently by containing the products to be tested which are conveyed by a carrier into a sealed test space and subjecting the same to the leakage test. CONSTITUTION:Plural pieces of semiconductor products 10 which are subjected to the force feeding operation of gaseous helium are pitch-fed by each pitch in an arrow A direction by means of pitch feed holes 30 while they are kept held in the holding holes 26 of a carrier 14. These products are conveyed successively by each piece into a test vessel 12. The products 10 conveyed into the vessel 12 are contained in the sealed test space formed of the sealing rubber ring 18 of the vessel 12 and the sealing rubber ring 20 of a sealing cover 16. If a leakage defect exists in any product 10, gaseous helium leaks into the sealed test space and therefore this leaking gas is conducted through a conduit 22 into the body part of the tester, whereby the presence or absence of the leakage is detected. Since no direct force is exerted upon the products 10, the generation of the deformation defects of the products 10 is obviated.

Title: Lock mechanism for magnetic disk device
Inventor: ISHII NORIYOSHI
IPC: G11B21/22
Filed: 1988-02-02
Abstract: PURPOSE:To ensure a locking operation and to ease the management of the subject mechanism in spring constant, natural spring length and assembly dimensions by using springs having such spring characteristics that when a plunger is protruded by overcoming residual magnetic flux, a strong spring force is generated, and when the plunger is sucked in, a weak spring force is generated. CONSTITUTION:When an electric current of a coil 4 is cut off, a force for separating the plunger 2 from a yoke 5 by overcoming the residual magnetic flux is generated from both hard spring 3b and soft spring 3a. When the plunger 2 and the yoke 5 are once separated, the plunger 2 is accelerated by the hard spring 3b and the soft spring 3a to be apart from the yoke 5, whereas since the hard spring 3b is shorter in its natural length than a moving range of the plunger 2, the plunger 2 is accelerated on the way by the soft spring 3a only to be stopped in a position where its indenter 1 is interlocked with an indented part 6. By this method, the management in spring constant, natural spring length and assembly dimensions is eased, ensuring the operation of the lock mechanism concerned.

Title: Crop shear cutting control method and device

Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To eliminate shape confirmation monitoring work after crop shear cutting by an operator by criminating if cutting of a rolled material is good or bad according to oscillating acceleration and a pulse signal from a pulse transmitter. SOLUTION: It is discriminated if oscillating acceleration 9a is due to oscillating acceleration from a bearing or the like with the rotation of crop shear cutting edge drums 8a, 8b or oscillating acceleration 9a by an impact with a cutting edge 8c at the time of cutting a rolled material 1, by means of computation by a combination of a frequency-classified signal from a pulse transmitter 14 with a cutting control microcomputer 5, which is obtained by converting a pulse signal 14a from a pulse transmitter 14 mounted on a reduction gear 13 into crop shear cutting edge moving angle, and data table values such as width, thickness and others of a hot bar obtained from a host computer 12. It is thus possible to discriminate the cut contour of the head part of the rolled material 1 by a calculating discrimination for identifying good or bad cut contour of the rolled material 1.
