Title: Preparation of isobutylene polymer having functional group
Inventor: YAMANAKA YOSHINORI
IPC: C08F10/00
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To introduce a functional group with good productivity by mixing an alkenyl-terminated isobutylene polymer with a plasticizer in an inert gas atmosphere and reacting the mixture with a hydrosilyl-contg. compd. in the presence of a platinum catalyst. SOLUTION: An isobutylene polymer contg. at least one terminal alkenyl group and having a no. average mol.wt. of 500 to 200,000 (e.g. an isobutylene polymer contg. a terminal vinyl group) is mixed with a plasticizer (e.g. a paraffin plasticizer) in an inert gas atmosphere. The mixture is then reacted with a compd. represented by the formula (wherein R<1> and R<2> represent a 1-20C alkyl, a 6-20C aryl, or an (R')3 SiO group ; R' represents H or a 1-20C monovalent hydrocarbon; X represents a hydroxyl group, a halogen, an alkoxyl, or an acyloxyl; (a) is 0 to 3; (b) is 0 to 2; and (m) is 0 to 18) (e.g. dimethoxymethylsilane) in the presence of a platinum catalyst to prepare an isobutylene polymer having a functional group. This method can inhibit the formation of a reaction inhibitor, thus permitting the hydrosilylation to stably proceed.

Title: Magnetic head and its production
Inventor: UEMURA KIYOHIRO
IPC: G11B5/187
Filed: 1992-12-14
Abstract: PURPOSE:To obtain a sufficient fusion strength by low-temp. fusion and to improve the magnetic characteristic by forming the gap of a magnetic head close to a magnetic core with a layer having a high content of SiO2 and the central part with a layer having a low content of SiO2. CONSTITUTION:The magnetic gap 2 held between a couple of magnetic cores 1a and 1b and close to the cores is formed with a layer 4 having a high content of SiO2 and the central part with a layer 5 having a low content of SiO2 such as lead glass. Consequently, the cores 1a and 1b are formed at a low temp. of <=600 deg.C, and a sufficient fusion strength is obtained. Meanwhile, since the layer 4 is placed close to the cores 1a and 1b, the mutual diffusion of the core and gap material is suppressed, and an excellent magnetic characteristic is obtained. Further, the boundary between the cores 1a and 1b and the gap 2 is made clear, and the optical measurment of the magnetic gap is accurately taken.

Title: Drive power controller for independent left/right wheel drive vehicle
Inventor: YOKOTE MASATSUGU
IPC: B60K17/356
Filed: 1994-12-15
Abstract: PURPOSE: To inhibit the behavior change of an automobile by controlling drive power applied to the other drive wheel when either one of left and right wheel drive power stops due to a failure while turning. CONSTITUTION: When a drive source monitoring part 7b detects the drive disable of either left and right drive motors 3R and 3L for front wheel, a failure drive source judgment part 7c judges whether the drive disable occurred at the outer- wheel side in turn direction or the inner-wheel side in turn direction based on the turn direction which is judged by a turn direction judgment part 7a. Then, when an electric motor 3R judges drive disable as the outer-wheel side drive source in turn direction, the supply power for the electric motor 3L at the inner-wheel side in turn direction is gradually reduced, the electric motor 3L is stopped in a specific amount of time, and at the same time the power supply to the electric motor 3R is instantly stopped.  Also, it similarly applies when the electric motor 3R at the opposite inner-wheel side in turn direction cannot be driven, thus inhibiting the behavior of the automobile and improving safety.

IPC: H01M8/02
Filed: 1990-11-30
Abstract: PURPOSE:To take out an electric energy with a high converting efficiency by making the sectional area of a groove for passing a fuel gas in a unit cell relatively smaller than the sectional area of a channel for passing an oxidizing agent gas to constitute the gas passages of a cell stack. CONSTITUTION:The groove width of a fuel gas passing groove 5c formed on an anode electrode 3a is made relatively smaller than the groove width of an oxidizing agent gas passing groove 5b formed on a cathode electrode 3b to constitute a unit cell.
