Title: Schedule operation system for nc processing machine
IPC: G05B19/4155
Filed: 1992-03-27
Abstract: PURPOSE:To properly restart a schedule operation in relation to the precedent schedule operation and without requiring any special labor even though the schedule operation is occasionally interrupted. CONSTITUTION:A man-machine controller 19 contains a schedule data file 23 and is connected to a CNC device 7 to transmit the data. The controller 19 sends the schedule data stored in the file 23 to the device 7 and counts the machining completion frequency of each machining job by the signal received from the device 7. Then the controller 19 calculates the unexecution frequency of an interrupted machining job when an interrupted schedule operation is restarted based on the relation secured between the count value of the machining end frequency of the machining job decided in an interruption state and the scheduled execution frequency. Then the execution frequency of an NC program of the interrupted machining job is corrected into the unexecution frequency based on the schedule data. This data is sent to the device 7.

Title: Protective functional initiator for production of polymer having terminal functional group
Inventor: ROBAATO CHIYAARUZU BENINGU
IPC: C07F7/18
Filed: 1995-03-29
Abstract: PURPOSE: To enable the polymerization to be initiated at comparatively low temperatures and to be advantageously carried out by initiating the polymerization of an unsaturated monomer with the use of a specific lithium initiator to carry out the polymerization.  
     CONSTITUTION: The polymerization of an unsaturated monomer (e.g. butadiene) is allowed to be initiated by using a lithium initiator of the formula [wherein A'' is cyclohexyl or a group of -CR'R"- (wherein R' is a 1-10C linear alkyl; and R" is H or a 1-10C linear alkyl)]. According to the above method, at a commercially advantageous polymerization temperature higher than as in the case of similar initiators having a linear bridging group linking oxygen with lithium, the 'dead' initiator is initiated in a surprisingly low amount (i.e., with a higher effectiveness) and the protection removal is simpler than as in the case of similar initiators and the initiator is more effective for giving a diene polymer having a uniform and controllable fine structure than similar initiators. The produced polymer is simply end-capped and hydrogenated to form an anionic polymer having one or more terminal functional groups, e.g. OH groups under commercially attractive conditions.

Title: Connected terminal identifying system
Inventor: TANAKA KEISUKE
IPC: H04M11/00
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To reduce a communication tariff for the transfer of a temporarily responded call to another terminal at the time of call incoming by avoiding such transfer when respective terminals in different communication forms are commonly connected to a line. SOLUTION: When identification information showing the class of a call originating terminal is received at the time of call origination from this call originating terminal, at an exchange, this identification information is transmitted to the side of call incoming terminals 3 (3A-3C) together with a caller number before the transmission of a calling signal. When the identification information is received, at a switching device 4 provided on the preceding stage of each call incoming terminal 3, the class of the call originating terminal 3 is identified, the same class of call incoming terminal as this call originating terminal 3 is selected, and the calling signal from the exchange is sent out. As a result, the target call incoming terminal 3 can be immediately called.  Therefore, the useless transfer for transferring the temporarily responded terminated call to the other terminal at the time of call incoming is avoided so that useless charging during this transfer can be prevented.

Title: Fixing device for jib
Inventor: ERDMANN GERD
IPC: B66C23/693
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To stabilize the extendable fixing part of a telescopic jib and prevent reduction in the structural strength of the jib by arranging a plurality of fixing pins at the respective inner extendable parts so as to be engaged with a bearing part arranged facing the pins at the middle part of a side web in a vertical direction at the outer extendable part. SOLUTION: The outer extendable part 1 is divided into an upper part 1a, a middle part 1b, and a lower part 1c on its left side. Under load conditions such as a condition where a load is lifted by a jib, tensile stress acts on the upper part 1a of a side web so as to act most at the upper edge part, compressive force acts on the lower part 1c so as to act most at the lower edge part. At the middle part 1b of the side web, the stress resulting from bending load does not exist at all or exists slightly. A fixing device is arranged in this member, and penetrates through necessary members such as a bearing part 5, thus even if stability of the jib is reduced as a whole, it can be considered to be negligible.
