Title: Outlet for liquid of paper-made pack
Inventor: IO KAZUAKI
IPC: B65D5/74
Filed: 1990-06-13
Abstract: PURPOSE:To make it easy to open the mouth by a structure in which a paper- made pack is closed at the top by folding in ridges along the dotted lines defining an outlet for liquid and by folding in hollows along the other dotted lines and a rectangular part is altered to a trapezoid by a slight change in the length of sides. CONSTITUTION:A paper-made pack is designed to fold in ridges along dotted lines 3-7, 6-7, 7-8, and 9-10 which define the outlet for liquid and fold in hollows along the other dotted lines; by folding the pack as designed its top can be closed. A rectangular part defined by points l, 5, 15, and 14 is altered to a trapezoid by a slight change in the length between the line connecting the points 5 and 15 and the connecting the points 1 and 14. By pulling apart the opening ends of the pack an opening defined by points 2, 3, and 4, showing the inside, can be formed and by pulling the opening outward a mouth can be opened in the pack easily. The formation of a trapezoid for a rectangle l-5-15-14, that is, a slight change in the length between the line 5-15 and the line 1-14, when the pack is folded into shape and forms a fourfold layer, results in a stagger between overlapped layers at the top edge so that good contact can be ensured when adhesion is effected by application of pressure.

Title: Sif converter
Inventor: IMAIZUMI HIDEO
IPC: H04N5/62
Filed: 1991-06-26
Abstract: PURPOSE:To demodulate an audio with a single SIF circuit and to decrease the number of parts by reducing a carrier leakage of a circuit which converts plural SIF signals each of which has a different frequency into a SIF signal of a single frequency. CONSTITUTION:Three SIF signals which were inputted into a terminal 15 and each of which has a frequency different from others by 500kHz respectively, are inputted into a frequency conversion circuit 17 by way of a wide band filter 16. The circuit 17 performs a frequency conversion in correspondence with an output frequency of 500kHz from an oscillator 18 for a SIF signal of 6MHz to be outputted. Then, by making a carrier leakage of the circuit 17 smaller, the level of the original SIF signal is lowered so that a 6MHz signal of a higher level is obtained. Besides, since the level of a coexisting NICAM signal is also lowered, an effect to the 6MHz signal decreases. The output signal from the circuit 17 is amplified and detected by a SIF circuit 21 by way of an HPF 19 which shuts off a carrier signal and a 6MHz resonator 20. By this, the audio can be demodulated by single SIF circuit, resulting in decreased numbers of parts.
