Title: Magnetic recording medium
Inventor: ASANO MASANARI
IPC: G11B5/70
Filed: 1983-06-10
Abstract: PURPOSE:To increase the dispersibility of magnetic powder and to improve the required properties such as the wear resistance by incorporating a compound having epoxy constituent residues and at least two phosphoric ester residues in the molecule into a magnetic layer. CONSTITUTION:A compound having epoxy constituent residues and at least two phosphoric ester residues in the molecule has a remarkably improved dispersing effect because of the residues. In order to produce a dispersing effect, a dispersant is generally required to have a hydrophilic moiety having fitness for magnetic powder and a hydrophobic moiety having fitness for a binder. Since said compound has plural moieties capable of controlling the hydrophobic property and plural moieties capable of controlling the hydrophilic property, the dispersing effect of the compound is easily controlled as compared to a conventional dispersant, and it can be properly set in a stage for synthesizing the compound. The dispersing effect depends largely on the number of carbon atoms in hydrocarbon groups in the phosphoric ester residues, the kind and the mol.wt. of the epoxy constituent residues, and more phosphoric ester residues in the molecule produce a more significant dispersing effect. A magnetic layer 2 contg. the dispersant as well as magnetic powder, a binder, etc. is formed on a support 1 by coating to obtain a magnetic tape.

Title: Apparatus for changing speed of transmission for vehicles
Inventor: KONRAATO ETSUKAA
IPC: F16H59/18
Filed: 1978-08-28
Abstract: To improve vehicle operator comfort and safety and to reduce wear and tear on the automatic transmission, the apparatus prevents an upshift whenever the accelerator pedal is released very quickly. The apparatus stores the load signal which prevailed when the load was abruptly reduced, thereby simulating to the transmission controller a continuation of high load and preventing an undesired upshift, for example in downhill operation and during roll-outs. Normal load signals are restored whenever the accelerator pedal is returned to a predetermined point. In one embodiment, the stored load signal is a hydraulic pressure and in another embodiment, for use with an electronic transmission controller, the load signal is an electrical signal. In a third embodiment, the upshift control signal from the controller to the transmission is interrupted when the apparatus indicates a complete release of the accelerator pedal.
