Title: Conveyor carriage
Inventor: KITA HIROAKI
IPC: B65G39/18
Filed: 1988-12-27
Abstract: PURPOSE:To ensure the conveying work by means of simple transferring work, even if an article to be conveyed is deformed, by forming the rollers of a roller conveyor on a carriage by means of a pair of large-diameter parts and a small-diameter part lying between the large-diameter parts. CONSTITUTION:A roller 9 of a driven-type roller conveyor on a conveyor carriage is fitted from outside into roller shafts 9a, which are located between both supporting members 8, in a freely rotatable manner, so that the roller 9 is formed with a pair of, or right and left, large-diameter parts 9A and a small-diameter part 9B, which is situated between the large-diameter parts 9A. With this, when a pallet 40, which is supported by a pair of, or right and left, driving chains 43, is transferred to the roller conveyor, this pallet 40 is supported by both large-diameter parts 9A. Therefore, a deflection T of the pallet 40 can be absorbed by a step H which is produced between the large-diameter parts 9A and the small-diameter part 9B. Accordingly, with simple transferring work, the conveying work can be performed as expected without the lower, middle part of the pallet 40 colliding with the small-diameter part B. When there is almost no deflection because of a narrow article like a bucket 41, the conveying work is performed, using the small-diameter part 9B, as shown by an imaginary line in the figure on the right.

Title: Automatic resending request method for defectively received message and device for performing method thereof
Inventor: MARUKU DARUMON
IPC: H04L1/18
Filed: 1990-11-28
Abstract: PURPOSE: To reduce transmission delay by judging that an N-th reception response is a negative response when the response cannot be received. CONSTITUTION: In a duplex digital telephone linking device, control information sent from the outputs 10 to 12 of an HDLC element 8 is applied to the inputs 13 to 15 of a microprocessor 5, which executes a 'Go-Back-N ARQ' protocol by using the information. The protocol supposes that a reception response received in an incorrect state is a positive response when one reception response is not correctly received but its preceding reception response is correctly received and similarly supposes that succeeding (N-1) reception response which cannot be correctly received are also positive responses, and when the N-th reception information cannot be correctly received in these conditions, the reception response is rejected and N blocks corresponding to N reception responses which are not correctly received are resent. Consequently, time waiting for responses can be shortened.

Title: Dc feedback circuit
Inventor: KAWAGUCHI TOSHIHARU
IPC: H04B1/26
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To obtain a DC feedback circuit that stably suppresses a DC offset even when a base band filter is present in a feedback loop that is operated for a non-signal period. SOLUTION: A sample-and-hold circuit 7 detects a DC component appearing at an output terminal 6 by a mixer 2 and an base band filter 5 for a non-signal period and stores the DC component in a hold capacitor C, and keeps the DC component stored in the capacitor C for periods other than the non-signal period. A comparator 9 compares the DC component with a reference voltage Vref, outputs a signal in response to the result to a level shift circuit 4 inserted in a base band signal path, which shifts a level of the DC component to suppress the output DC offset based on the outputted signal. Through the control above, for the non-signal period, the DC feedback loop is operated to make the feedback loop stable by changing a frequency characteristic of the filter so as to suppress the DC offset at the signal output terminal 6, and the control signal given to the DC level shift circuit 4 is maintained for periods other than the non-signal period thereby attaining suppression of the DC offset for all the periods.
