Filed: 1991-09-06
Abstract: PURPOSE:To provide a steering angle control device in which an inexpensive yaw rate (n) stage differential value detecting sensor can be used as a feedback signal sensor instead of an expensive rate gyro. CONSTITUTION:A feedforward control unit 7 carries out operation on a rear wheel steering angle deltac from a steering angle theta and a vehicle speed V so as to generate a target yaw rate. A feedback control unit 8 finds a steering angle compensation quantity DELTAdelta such as eliminating a difference between estimate yaw angular acceleration to be generated in rear wheel steering by means of a command steering angle delta to a vehicle and actual yaw angular acceleration (d<2>/dt<2>) phi detected by means of a sensor 6, and a steering angle correction unit 9 finds the command steering angledelta by means of delta=deltac-DELTAdelta, and commands it to a vehicle rear wheel steering actuator in the vehicle. Thereby, prescribed operation can be carried out by using not an expensive yaw rate sensor but an inexpensive yaw angular acceleration sensor 6 as a feedback signal sensor, so that cost-effectiveness is excellent.

Title: Platinum black air cathode, its operation method and a laminar gas diffusion electrode having an immediate layer combination
Inventor: FURANKU SOROMON
IPC: C25B11/12
Filed: 1989-09-01
Abstract: A platinum black air cathode has an active layer and a support layer. The active layer comprises platinum black plus hydrophobic binder, typically a fluorinated polymer. The support layer may be made up from carbon black bound with a halopolymer binding agent. Such combination can provide for economical utilization of active ingredient without sacrifice of cathode structural integrity. To assist in this structural integrity, a thin support mesh may be used, preferably with the support layer. There can also be employed between the active layer and the support layer a porous bonding layer, which can find broader utilization with layered gas diffusion electrodes in general. For highly desirable, greatly extended operation of the platinum black air cathode, the cathode can be operated intermittently, or anodically polarized or be subjected to infrequent voltage suppression, as well as being involved with any combination of the foregoing.

Title: Brake fluid pressure controller
Inventor: NANAHARA KENJI
IPC: G05B11/32
Filed: 1993-09-13
Abstract: PURPOSE:To improve a braking feeling by generating a final period catching feeling by the brake fluid pressure control for controlling brake operating pressure through a process of taking brake operating force corresponding pressure as pilot pressure. CONSTITUTION:A device is provided with a fluid pressure control valve for taking master cylinder fluid pressure Pm as pilot pressure, and the fluid pressure control valve controls brake fluid pressure Pw so as to govern it by adjustment of external control force by a solenoid on the basis of a command voltage Ve (CMD). The command voltage Ve (CMD) is calculated by including a compensation voltage Vek wherein the master cylinder fluid pressure Pm is multiplied by a proportional element of the first order lag on the pressure increasing side as the variable control amount. The compensation voltage Vek is gradually increased by the value of the time constant T in braking and finally settled into the value to be determined by the formula; Kk (proporational gain) X Pm. Accordingly, the brake fluid pressure Pw is slowly increased from during braking to the final period, thereby the final period catching feeling can be generated. When the proportional gain Kk is varied by the car speed or the across G, the elaborate control matched to the traveling state can be realized.
