Title: Apparatus for supplying label between half molds before injection of thermoplastic material in injection molding machine
Inventor: RUYUUDORUFU GURADEISU
IPC: B29C45/26
Filed: 1988-12-22
Abstract: PURPOSE: To largely enhance a manufacturing speed by dropping a label discharged from a supply means attached to an injection molding machine while half-casting molds are opened to the molds, and disposing it in a lower air gap. CONSTITUTION: When a thermoplastic material is injected in air gaps 3, 4 so that a label E (smaller than the air gap) is integrated with the material during molding, at the time of placing half-casting molds 1, 2, a pin 15 prevents the label discharged from a supply unit attached to an injection molding machine from dropping into a groove 7 in the groove 8. The label is fed in the groove 8 during separating movement of the mold 1 from the mold 2 until the label is brought at its lower end into contact with partial bottoms 8a', 8b'. The label is passed through a pin 16 not operated. A next label is supplied into the groove 7 when the mold 1 is disposed at its left end immediately after arriving at the bottoms 8a', 8b', and dropped to the grooves 7, 8 until it is brought at its lower end into contact with the pin 16.  These pins are operated by passing the preceding label to project between the parts 8a and 8b.

Title: Ninety-degree phase shifter
Inventor: YOSHIMURA TSUTOMU
IPC: H03K5/13
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To obtain a 90 deg. phase shifter which has a uniform input load and prevents phase offsetting. SOLUTION: Transistors(TR) MP1 and MP2 supply currents I0 to nodes K and L respectively, and TRs MN10 and MN11 draw mutually equal currents out of the nodes K and L respectively. A parallel connection of series-connection body N1 and N2 draws a current I1 out of the node K, only when exclusive OR of clocks S1 and S2 is 'H'. A parallel connection of series-connection bodies N3 and N3, meanwhile draws a current I1 out of the node L, only when the exclusive OR of the clocks S1 and S2 is 'L'. Once the current I1 is drawn out of the node K, a current I1 flows out of the node L and when the current I1 is drawn out of the node L, a current I1 flows in the node L. The series- connection bodies N1 to N3 receive the clocks S1 and S2 and their inverted signals S1B and S2B at one of the gates of the TRs MN1 to MN8, so that the input loads become uniform.
