Title: Ultrasonic welding
Inventor: WADANOBE NOBUJI
Filed: 1977-12-26
Granted: 1981-10-22
Abstract: For ultrasonically welding two components, particulary of plastics, the components are formed so that they can be manipulated to interlock with each other before welding.  The components may snap-fit to interlock abutments, or may be joined by screw threads or a bayonet joint, and the joint may be a bead, scarf or dovetail joint, the arrangement eliminating the need for additional locking with pegs or clamps.  After interlocking, pressure may be applied to effect relative movement of the components before welding, which pref. takes place in the interlocked region.  The method is applicable to e.g. diaphragm or check valves.

Title: Method of making a paper pattern for dyeing
Inventor: ISOBE MINEO
IPC: B41C1/14
Filed: 1983-07-14
Granted: 1986-02-26
Abstract: The blunt edge of a blade, which is heated to a temp. slightly less than the melting point of the film material used for the paper pattern (3), is passed over it following the lines of the pattern. The combination of the blade and the heat softens the material edges and results in cutting the film material. The cut film material, representing the pattern, is then removed from its supporting mesh. This process allows paper patterns to be produced by relatively unskilled operatives.

Abstract: Transistors are installed on a side of a rear output line  of a converter to charge a capacitor  (3),  and  a  voltage  dividing resistor detects the level of a voltage for charging the capacitor to selectively  drive  the  transistors  in  accordance  with  the current  mode.  When  a  cage  operating  command   is   inputted, differential amplifiers (24,28) amplify the difference between the detected  voltage  and  a  reference  voltage,  and  a  darlington transistor  (26)  amplifies  the  outputs  of   the   differential amplifiers (24,28), while a mode  selecting  circuit  selects  the operating modes. The apparatus simplifies  the  electric  circuit, and therefore, the control reliability is  improved,  as  well  as saving the manufacturing cost.

(I) is prepd.  by  solution  polymerising   2,5-dialkoxy   terephthal aldehyde of formula (II) with  equivalent  mole  of  1,4-phenylene diamine   or   benzidine   in   a   mixed   solvent     comprising 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone and N-methyl- 2pyrrolidone, at 80 deg.C for 24 hrs. (I)  has  0.13-0.17  dl/g  of inherent  viscosity  and  4.8  x  10-6  -  1.1  x  10-2  s/cm   of electro-conductivity. In the formulas, X is phenyl or biphenyl;  R is C8-18 alkyl; p is 3-30.

Title: A letter interpolation-circuit in osd apparatus
Inventor: KIM YONG-HWAN
IPC: H04N5/445
Filed: 1989-11-02
Granted: 1992-07-27
Abstract: The interpolation circuit is for displaying the oblique lines and the curved line of letters or diagrams smoothly.  The  circuit comprises a first and a second ROMs  (ROM1,ROM2)  for  storing  on screen display character data by font units, a first and a  second shift register (73,75) for shifting fonts stored in  the  ROMs,  a interpolation circuit (74) for comparing the shifted font  outputs and for generating interpolation data when stepwise fonts  occurs, a first and a second shift register selector  (76)  for  selecting font from the fonts shifted by the shift registers, and  an  adder (77) for adding the selected font and the interpolation data.
