Filed: 1985-07-12
Abstract: PURPOSE:To enable the recognition of the three-dimensional arrangement of an object by using a TV camera, summing a plurality of image signals from some different positions with signs alternately inverted and processing the data thus obtained. CONSTITUTION:When the push button 23 of a controller 20 is pressed, a motor 34 displaces a camera 1 to produce a pulse 102. The pulse 102 operates an A/D converter 2, a sign inverter 3 and the like and image data with signs alternately inverted are stored in an image memory 5. The data stored in the memory 5 for every horizontal scanning line are transmitted to a high speed Fourier transformer 6, in which a horizontal direction spatial frequency spectrum is obtained, and the spectrum of the whole screen is calculated by an adder 4. Thus, after a smoothing is conducted on the spectrum by operating a constant data memory 22, a multiplier 11, an interpolator 12 and the like, the spectrum is led to another high speed Fourier transformer 13 to be restored to an original image (point). This procedure is performed on every scanning line and the image of the object being measured is completed on another image memory 14. Therefore, the three-dimensional arrangement of a given object apart from the camera by a given range can be recognized.

Title: Heating type nozzle for injection molding and manufacture thereof
Inventor: JIYOBUSUTO ARURITSUCHI JIERAAT
IPC: B23P15/00
Filed: 1985-07-12
Abstract: This invention relates to an improved heated nozzle for injection molding and an improved method of manufacturing it. The nozzle has an elongated body with a melt bore extending generally centrally through it. The cylindrical outer surface of the body has a variable pitched spiral channel extending around it along its length. A helical electric heating element is embedded in the channel to form an integral structure by which the temperature of the hot melt can be maintained within a narrow range as it flows through the bore. The nozzle is manufactured by forming the body with the channel and bore either by investment casting or machining. The heating element is wound in the channel and a bead of nickel brazing paste is run along the top of it. The nozzle is then heated in a vacuum furnace to braze the heating element in the channel. The highly conductive nickel completely covers the heating element and is fused to both the heating element and the walls of the channel. Thus, a low cost integral nozzle is provided which during use efficiently dissipates heat from the element to prolong its effective life, and applies the heat uniformly along the melt bore.

Abstract: PURPOSE:To supply exact magnetic fields by the simple method and to obtain reliable function information by forming such sequence as to impress the inverted magnetic field after impression of an irradiation pulse then to further impress the inverted magnetic field so as to generate an echo signal. CONSTITUTION:The point X of the time when the echo signal is generated is set on a timing signal 311 for signal measurement.

The gradient magnetic field 302 is thereafter impressed and the echo signal 304 is outputted at the point of the time when the magnetic field intensity X impression time is equaled to that of the gradient magnetic field 301. The impression time of the gradient magnetic field 301 is adjusted to match the time from the irradiation signal 313 to the generation of the echo signal 304 with the echo time when the point of the time of the output thereof does not coincide with the point X of time. The gradient magnetic field 306 is impressed in the inverted state between the inverted gradient magnetic field 301' and the gradient magnetic field 302 in such a manner and the ratio of the magnetic field intensity X impression time thereof is so set as to attain the gradient magnetic field 301': the gradient magnetic filed 306: the gradient magnetic field 302=1:2:1. The echo signal is, therefore, generated with no time delay at all at the point X of time.
