Title: Four-wheel-drive vehicle
Inventor: AZUMA HARUMI
IPC: F16H48/295
Filed: 1987-10-28
Abstract: PURPOSE:To secure the traveling faculty of a vehicle by installing a flywheel position sensor, position sensor output detecting means, and a prohibiting means and precisely detecting the generation of anomaly even if said anomaly is generated in the flywheel position sensor. CONSTITUTION:When the output signal of a flywheel position sensor changes from the disconnection state of a flywheel device 61 to the connection state, this change is detected by a position sensor output detecting means. When it is judged that the change of the output signal of the position sensor is generated in the state other than the switching from the two-wheel-drive state to the four-wheel-drive state of a transfer device 6, by a prohibiting means which receives the output of the position sensor output detecting means, said position sensor is considered to be in an abnormal state, and the switching of the center differential gear of the transfer device 6 into free state is prohibited. Therefore, the switching to the center differential gear free mode of the four-wheel-drive is prohibited irrespectively of the actual disconnection state of the flywheel device 61, and the traveling performance of the vehicle can be secured.

Title: Manufacture of semiconductor device
Inventor: SUGAWARA TAKEHISA
IPC: H01L21/768
Filed: 1989-10-19
Abstract: PURPOSE:To apply a uniform depression pressure to a lead which is thermo- compression bonded and to enable stable bonding even if there if warp in a package by arranging a copying jig between a supporting base and the package. CONSTITUTION:A pin of a copying jig 9 has different lengths within a range of a larger value than a maximum value of warp of a package substrate and is planted in different arrangements. That is, a part having small warp projecting downward in a substrate 2 is supported by a long pin; and a part having large warp projecting downward receives an intense repulsion power since it bends a long pin and reaches a short pin. If a substrate 2 has warp projecting upward, a reverse operation works. Therefore, a uniform depression pressure is applied to a TAB lead 31 and a lead pattern part 41 which are in contact with a compression bonding head 1 even if the substrate 2 of a package has warp when looked at from the side of the compression bonding lead 1. Stable thermo-compression bonding can be realized in this way.

IPC: C08F8/42
Filed: 1984-12-26
Abstract: PURPOSE:To obtain selectively a precursor of a substituted p-methylstyrene polymer, by reacting a p-methylstyrene polymer with an organolithium compound. CONSTITUTION:A precursor is obtained by reacting a p-methylstyrene polymer having repeating units of a p-methylstyrene skeleton with an organolithium compound.

As the organolithium compound, butyllithium is preferable. The reaction of the PMS polymer with the organolithium compound is carried out in a solvent (e.g., hexane) inert to the organolithium compound. A substituted styrene polymer can be obtained by reacting said precursor with a delithiating agent, and it is useful as a functional polymer, especially, when the substituent is a functional group.
