Title: Hydraulic controller of continuously variable belt transmission for vehicle
Inventor: HAYASHI TAKASHI
IPC: F16H59/70
Filed: 1990-02-01
Abstract: PURPOSE:To prevent the slip of a driving belt from occurring by installing an engine speed variation detecting means, detecting a sudden change in engine speed, and a tension control pressure booster means heightening the extent of tension control pressure as far as the specified one at a time when the sudden change is detected, respectively. CONSTITUTION:In a forward traveling state when a lockup clutch 36 of a vehicle is engaged, the second line hydraulic pressure is accurately approximated to an ideal curve, but optimum control of the second line hydraulic pressure is prohibited before time equivalent to the criterion value elapses since engagement of the lockup clutch 36 has started. During an engine speed lowering period as long as the specified period from the engagement of the lockup clutch 36, execution of the second line hydraulic optimum control is checked and the second line hydraulic pressure is heightened up to the fundamental output pressure, so that the slip of a transmission belt 44 attributable to enhancement of transfer torque by rotational inertia in the crankshaft 26 of an engine 10 and the input side rotor of a hydraulic coupling 12 is thus eliminated.

Title: Melting furnace
Inventor: HATTORI HIDEMI
IPC: C21C7/072
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To obtain a melting furnace which is decreased in the exchange frequencies of a porous plug for blowing gas into molten metal to reduce a maintenance cost and is improved in an operation rate by cladding the flanks and base of the porous plug with covers formed of a corrosion resistant material. SOLUTION: The flanks and base of the porous plug 4 for removing the harmful gases and impurities in the molten metal by bubbling the inert gas into the molten metal are clad with the covers 7 formed of the corrosion resistant material, for example, stainless steel plate. The porous plug is connected to piping 6 for feeding the inert gas from the bottom, by which the progression of oxidation at a high temp. is retarded and the life is prolonged. The porous plug 4 is mounted at the base of the melting furnace in such a manner that the front surface of the porous plug 4 comes into contact with the molten metal in the furnace. The inert gas is supplied to the molten metal from a supply source connected to the piping 6.  Since the flanks and the base are clad with the corrosion resistant material, the leakage to the flanks and the base does not arise and the entire inert gas is supplied from the front surface thereof into the molten metal.

Filed: 1986-02-07
Abstract: PURPOSE:To prevent a sudden change of the behavior of a vehicle accompanying the change of characteristics and improve safety by providing a characteristic changeover means for rear wheel steering ratio, a vehicle speed detecting means, and a characteristic change restricting means for changing the rear wheel steering ratio characteristic when the vehicle speed is below the defined value of a low speed or zero according to both of said means.

This is to change the characteristic of the steering ratio on condition that the vehicle speed is zero or below a defined speed, seeing that when a vehicle speed is low a change of the behavior of a vehicle accompanying the change of the steering ratio characteristic is also gentle. Accordingly, since the change of the steering ratio characteristic is carried out in a condition that the vehicle speed is a low speed or zero, a sudden change of the behavior of a vehicle accompanying the change of characteristics can be prevented, improving safety.

Filed: 1991-01-23
Abstract: PURPOSE:To efficiently produce a magnetic recording medium having certain qualities by providing a uniform roughness gradient of the surface of a polishing tape in the longitudinal direction of the tape to polish the surface of a magnetic recording medium. CONSTITUTION:A polishing layer containing abrasive particles and a binder is formed on a supporting body comprising a resin film by applying a mixture of two coating materials in the following manner. These two coating materials are prepared by mixing and dispersing abrasive particles and binders for different period of dispersion, one material (B)has short mixing and dispersing time, the other material(A)has long mixing and dispersing time. When the mixture is applied on the supporting body, the proportion of the coating material B is larger in the initial stage, but with time of coating, the proportion of (B) is gradually decreased while the proportion of (A) is increased. Thus, the polishing tape is cured to obtain a tape having uniform roughness in the longitudinal direction.
