Abstract: PROBLEM TO BE SOLVED: To attain cost-down by enabling the use of a small capacity capacitor as a power source circuit for backup. SOLUTION: Concerning an integrated IC 120 having a demultiplexer 108 and an IC card I/F part 114, the I/F part 114 requires the backup of a power source. The integrated IC 120 has a main power source terminal 121 and a backup terminal 123 to connect a capacitor 130 as the power source circuit for backup. The main power source terminal 121 is connected to the power source line of the demultiplexer 108 and connected through a DC/DC converter 124 to the power source line of the I/F part 114. The power source line of the demultiplexer 108 and the power source line of the I/F part 114 are turned into equivalently separated state by the converter 124. At the time of backup, power is supplied from the capacitor 130 only to the I/F part 114 and power consumption is suppressed.

Title: Connection system for plural paths
Inventor: TSUBOI YOJI
IPC: H04Q3/545
Filed: 1986-07-11
Abstract: PURPOSE:To set plural paths at a time by connecting an incoming call to an incoming terminal through an incoming exchange after confirming that all calls produced from communication requests are received by discriminating information. CONSTITUTION:The originating terminal and the incoming terminal are defined as a subscriber terminal 8 and a subscriber terminal 9 respectively. When a subscriber line exchange (originating exchange) 1 receives a communication request from the terminal 8 to require plural paths, the exchange 1 sets those requested paths independently of each other and decomposes these paths into plural calls added with the discriminating information showing that the calls are produced from the same communication request. Then the exchange 1 sets paths in response to those calls. While a subscriber line exchange (incoming exchange) 4 storing the terminal 9 confirmes from the discriminating information that all calls produced from a single communication request are received and carries out the incoming connection to the terminal 9. Thus it is possible to set simultaneously plural paths between both exchanges 1 and 4. Then the terminal 8 can decide quickly the propriety for connection of the terminal 9.

IPC: D05B3/02
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To enable to realize corner sewing without generating a blank at a corner part, by setting the rotation angle of cloth by a corner sewing cloth rotation angle setting key in corner sewing by pattern sewing and making a bottom position stopping point at a proper point on right or left side corresponding to the cloth rotation direction. SOLUTION: On corner sewing by pattern sewing such as zigzag sewing, rotation direction of corner sewing and cloth are preliminarily set by a cloth rotation angle setting key 4. During pattern sewing operation such as zigzag sewing of a sewing machine, when a bottom stopping key 3 is operated, the needle position is judged to be right or left by a signal from a needle oscillation detecting sensor 20, and whether the same matches the setting of the setting key 4 or not is judged. The judgement is executed by every one stitch step, and, if it does not match, sewing of the next stitch is carried out. If matches, whether the next stitch is on the maximum width position or not is judged. When it is not on the maximum width position, sewing of the next stitch is carried out, and, if it is on the maximum width, lower dead point stopping is carried out at that position. The cloth is rotated in that state and sewing is started again.
