Abstract: A method for manufacturing a dielectric sheet, includes the steps of extrusion molding a mixture including powder polytetrafluoroethylene and spherical silica at a temperature lower than or equal to a melting point of the polytetrafluoroethylene, and calendering a sheet body obtained by the extrusion molding. A mass ratio of the silica with respect to the polytetrafluoroethylene is 1.3 or greater. An average particle diameter of the silica is 0.1 ?m or greater but 3.0 ?m or less. A reduction ratio of the extrusion molding is 8 or less.

Abstract: There is provides liquid discharging apparatus including: head having nozzle; reservoir configured to store the liquid such that liquid surface is positioned higher than opening of the nozzle in a state that the reservoir stores the liquid of maximum storable amount; and atmosphere port connecting gas layer and outside of the reservoir. Inner diameter d of the nozzle and head difference h satisfy expression of ?hd/? cos ??4/g, provided that p is specific weight of the liquid, ? is surface tension of the liquid, ? is contact angle of the liquid in the nozzle and g is gravitational acceleration, the head difference h being difference in height between meniscus in the opening of the nozzle and the liquid surface in the state that the reservoir stores the liquid of the maximum storable amount.

Abstract: A brake force distribution control system comprising wheel speed sensing means S1, S3 which detect wheel speeds VWFR, VWRR of a front right wheel FR and a rear right wheel RR respectively, standard speed calculating means M1 calculating first speed value B and second speed value C from each of the wheel speeds VWFR, VWRR, and figuring out front medium value of VWFR, B and C and rear medium value of VWFR, B and C as standard wheel speeds VWSFR, VWSRR respectively, comparison means M2 calculating a difference between the standard wheel speeds VWSRR and VWSFR and driving means M3 operating a pressure control valve unit FV depending on the differences so as to modulate brake force of the rear right wheel RR relative to that of the front right wheel FR.

Abstract: In an electric control apparatus for a hydraulic brake control system of a vehicle, a feedback control portion is provided to produce a feedback control pulse signal indicative of a difference between a target slip ratio and an actual slip ratio. A feedforward control portion is provided to successively convert the target slip ratio in relation to a required braking force, a hydraulic braking pressure and an amount of hydraulic braking fluid, in sequence, and to convert the amount of hydraulic braking fluid into a feedforward control pulse signal. A pulse mixing circuit is connected to control portions to mix the control pulse signals for producing a mixed control pulse signal as a distinct control pulse signal. A driving circuit is connected to the pulse mixing circuit to control a hydraulic braking pressure applied to each wheel of the vehicle in accordance with the control pulse signal, regardless of the extent to which a brake pedal of the vehicle is depressed.
