Title: Delay control system for voice packet transmission
Inventor: MORIYA NOBUYUKI
IPC: H04L49/9023
Filed: 1982-02-04
Abstract: PURPOSE:To hold the quality of a speech regardless of variation in transmission delay time, by compensating the variation in transmission delay time according to the distribution of transmission delay in a packet switching network. CONSTITUTION:In the packet switching network 6, a voice packet is transmitted to a reception side through the repeating of packet switching devices 71-7n. The voice packet is stored in a buffer memory 15 for absorbing variation in delay time successively through an input terminal 14. Every time the voice packet is received, a voice packet reception time measuring circuit 16 measures the reception time by using a timer circuit 17 and supplies the measured time to a processor 13. The processor 13 finds the mean value of differences in reception time between succeeding voice packets and looks up the contents of a delay time storage part 18 consisting of an ROM on the basis of said mean value and the number of repeating packet switching devices to supply a delay time value to a control circuit 19 according to the contents. The control circuit 19 uses a timer circuit 20 to perform delay by the delay time value and then outputs the stored voice packets to an output terminal 21 on FIFO basis.

Title: Intermittent feeder of feed bar in transfer press
Inventor: MATSUSHITA KEIJI
IPC: B21D43/05
Filed: 1979-02-19
Abstract: PURPOSE: To apply the device as the feed bar intermittent feeder of the three-dimensional feeder by providing an unequal speed mechanism between a drive shaft and gear group and expanding the dwell range of the feed bar.  
     CONSTITUTION: When a jaw clutch 6 is moved downward to be engaged with the drive gear 5 on the lower side by an operation handle 8, the revolution of a drive shaft 3 is transmitted to the drive gear 5, by which the housing 12a of an unequal speed mechanism 12 is revolved. This causes the gear 10 secured to a crankshaft 13 to revolve the gear 19 intermeshed with this at an unequal speed continuous at a rate of one turn per half revolution. As a result of this, the range of the dwell in the return end and the dwell in the advance end becomes larger than that of equal speed revolutions. Hence, by performing the moving up and down of the feed bar 33 during this time, the device may be also employed as the intermittent feeder of the feed bar making three-dimensional operation.
