Title: Ultrasonic range finder
Inventor: TONE MASAYUKI
IPC: G01S7/52
Filed: 1984-12-19
Abstract: PURPOSE:To measure an approach distance with high accuracy, by providing a frequency divider which divides the frequency of a reference pulse and receives the control of a frequency dividing ratio by the definite figure-up output of a counter. CONSTITUTION:The transmission pulse transmitted from a transmission circuit 2 is applied to an ultrasonic sensor 1 and an ultrasonic wave is transmitted to an article 9 to be measured while the ultrasonic pulse reflected from the article 9 to be measured is amplified and detected by a receiving circuit 3. When the output of said circuit 3 exceeds reference voltage, an output pulse is generated in an amplitude comparing circuit 4. The transmission pulse of the circuit 2 and the output pulse of the circuit 4 are respectively inputted to a gate circuit 5 to determine the start and stop timings of the gate pulse. The gate pulse generated in the circuit 5 is added to a counter 6 to control the operation of the counter 6. The reference pulse generated from a reference pulse generation circuit 7 receives frequency dividing by a frequency divider 10 to be inputted to the counter 6 and a frequency dividing ratio is controlled by the figure-up output from the counter 6 outputted when the count number of the counter 6 became larger than a preset value.

Inventor: UCHIDA MUTSUO
IPC: F16L21/08
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To improve breakaway obstructing force of a fitting by fitting a ring leaving an outer circumferential groove to the spigot of a tube from the outside, letting molten metal flow in the outer circumferential groove by welding, welding the groove bottom part of the outer circumferential groove with the surface part of the spigot, and thereafter reheating the welded part so as to remove residual stress. SOLUTION: A projecting part 10 capable of engaging with a lock ring from the deep side of a socket is formed on the outer circumference of the extreme end part of the spigot 9 of a cast iron tube 8 to be connected through a slip-on type fitting. At forming the projecting part 10, a ring 15 having an outer circumferential groove is mounted on the outer circumference of the spigot 9, molten metal is let flow in the outer circumferential groove by a welding torch, and after the surface part of the spigot 9 is melted in integratedly with the groove bottom part, it is cooled and solidified. In this way the ring 15 is fixed to the spigot 9 by the molten metal, namely, weld bead 17, but in this case, the weld bead 17 and the circumference are heated by a burner 20 so as to remove residual stress of the welded part.  Hereby breakaway preventing force of the projecting part 10 to the lock ring on the socket side is improved.

Title: Temperature-controlled treatment for execution of epitaxial growth of material film
Inventor: JIYON TEI FUITSUCHI
IPC: C30B25/10
Filed: 1992-09-11
Abstract: PURPOSE: To enable a high-quality epitaxial growth, while the low temperature of a treatment chamber is ramped. CONSTITUTION: A substrate is preconditioned, and a surface protective film is formed on the surface of the substrate. Then, the substrate is put into a temperature-controlled treatment chamber (step 2). Using oxygen eliminating technology, oxygen and contaminants are eliminated from the treatment chamber before epitaxial growth has started (step 3). A processing gas, including an epitaxial growth seed, an oxygen eliminating seed, and other possible seeds is put into the treatment chamber at a low temperature (step 4). The processing gas and the surface protective film keeps the environment of the inside of the treatment chamber, eliminating contaminants from the surface of the substrate and preventing the growth of an existing oxide film prior to (in some cases, during) the epitaxial growth. The temperature of the treatment chamber is increased in stages, to start a high-quality epitaxial growth according to the decomposition of the surface protective film.
