Title: Synthetic controller for front and rear wheel drive force distribution and wheel load distribution
Inventor: YAMAMURA TOSHIHIRO
IPC: B60W10/10
Filed: 1990-05-02
Abstract: PURPOSE:To prevent the furtherance of the aggravation of a steering characteristic and the furtherance of the loss of drive force even if drive force distribution changes, by conducting correction control so that the more there may be an inner wheel racing amount or an inner wheel racing equivalent amount, the less or unincreasingly there may be a wheel load move ment amount on a wheel load distribution controller side. CONSTITUTION:Drive force is distributed to front and rear wheels by means of a controller (a) according to a front and rear wheel rotation speed difference. Also, the distribution of a wheel load is controlled by means of a controller (b) according to the load movement amount of each wheel. Meanwhile, an internal wheel racing amount or an internal wheel racing equivalent amount is detected by means of a detecting means (c) at the time of turning. And correction control is made by means of a correction controlling means (d) so that the more there may be the internal wheel racing amount or the internal wheel racing equivalent amount from the detecting means (c), the less or unincreasingly there may be a wheel load movement amount than at the time of normal control. As a result, at a vehicle which is mounted with the front and rear wheel drive force distribution controller and the wheel load distribution controller simultaneously, even if drive force distribution has been changed at the time of an internal wheel racing generation at the time of a high lateral acceleration turning, the prevention of the furtherance of the aggravation of a steering characteristic and of the furtherance of the loss of drive force is attained.

Title: Information recording medium and its production
Inventor: YABE MASAO
IPC: G11B7/249
Filed: 1987-05-12
Abstract: PURPOSE:To prevent disappearance of grooves and degradation in the reflectivity of a dye recording layer which allows writing and/or reading of information by a laser by providing said recording layer on an morphous polyolefin substrate. CONSTITUTION:The dye recording layer which allows the writing and/or reading of the information by the laser is provided on the amorphous polyolefin substrate. The solvent resistance to a non-hydrocarbon system such as halogenated hydrocarbon solvent is enhanced by using the amorphous polyolefin substrate as a substrate in such a manner. The good coating type recording layer is thus formed without allowing the substrate surface to be dissolved even if the substrate surface is not particularly subjected to an insolubilization treatment. The disappearance of the grooves on the substrate and the degradation in the reflectivity of the recording layer are thereby prevented and the high- performance information recording medium is obtd.

Abstract: PURPOSE: To use a screen effectively by continuing to project a TV received picture until picture information for one screen is all stored and then by projecting the picture informing.  
     CONSTITUTION: Once program assignment circuit 18 is operated, FFs 27 and 28 are reset by a signal from circuit 18, and consequently the Q output and Q' output of FF28 are held at low and high levels respectively to close gate 31 and open gate 32, so that a TV received picture signal will be supplied to display unit 6. Then, the information signal of the program is transmitted to generate a program coincidence output by program comparator circuit 17, and FF 27 is set with its Q output held at a high level, so that gate 30 will conduct. On the reception of a code signal showing the end of one-screen information on the program, the J terminal of FF28 is held at a high level through gate 30 to set FF28. Consequently, gate 31 conducts while gate 32 becomes unconductive, thereby supplying the pattern signal of picture information read out from main memory to display unit 6.
