Filed: 1978-11-29
Abstract: PURPOSE: To give full display of the functions of the knee protector and seat belt at the time of automotive collision by attaching one end of the seat belt to the center of the knee protector in the car width direction.  
     CONSTITUTION: One end of the seat belt 20 is so set at the center of the knee protector 10 in the car width direction as to pull back the knee protector 10 by means of the seat belt 20 at the time of collision. By so doing, the forward move of the knee protector 10 is curbed and the knee protector is caused to function without increasing the attaching strength of the knee protector 10. By pushing the knee protector 10 forward by means of the knee portion of a passenger, tension is given to the seat belt 20 at an early stage to restrain the passenger.

IPC: H04H60/06
Filed: 1995-05-23
Abstract: PURPOSE: To automatically interrupt and restart such a program that overlaps a periodical program by shifting the starting time points of all programs following a program whose broadcast time is extended except for the periodical programs. CONSTITUTION: An identification mark is added to the broadcast data stored in a storage means 11 to show a relevant program is periodical or not. A broadcast data correction means 16 inputs the designation of the program to be extended and its extension time and also the broadcast data of the storage 11 through a terminal 2. The means 11 also extends the broadcast time of the program to be extended and contained in the broadcast data and then delays the broadcast start time points of all subsequent programs by set extension time except for the periodical programs. Furthermore, the broadcast data are corrected so that the overlapping part of a program that conflicts with a periodical program due to the delay of its broadcast start time is broadcasted in an idle time band secured right after the periodical program.  A broadcast control data correction means 17 produces the broadcast control data from the corrected broadcast data, and an operation control means 14 automatically controls the output of programs based on the broadcast control data.

The oxidation reaction is performed by using DMSO as an oxidizing agent and phosphorus pentoxide as a co-reactant, further adding a tertiary amine simultaneously with the addition of the optically active alcohol at 30-60 deg.C. The DMSO of more than 1 molar time, the phosphorus pentoxide of 1-5 molar times and the tertiary amine of 1-2 molar times of the optically active alcohol is used.
