Title: Gas treating device using adsorbent mat
Inventor: TAKAHASHI SEIICHI
IPC: B01D53/81
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To surely device a driving net even though friction resistance in increased at an adsorption part and a desorption part by attaching driving bars to a driving net, fixing each end of the driving bar to a driving chain and fitting a friction reduction means on each roller shaft. SOLUTION: The driving net 9 is wound around each of the rollers 4 and an adsorbent mat 5 is piled thereon. The driving chain 16 is wound around sprockets 15 at both ends of each shaft 3, and the driving bars 17 are attached on the driving net 9 in the width direction of the driving sheet 9 at regular intervals in the longitudinal direction, and both ends are fixed to respective driving chains 16. Also between the driving net 9 and each roller 4, between the roller 4 and the shaft, and between the sprocket 15 and the shaft, friction reduction means such as bearings are interposed. Thus, a driving force of the driving chain is transferred to the driving net uniformly over the entire width via the driving bar and even though the friction resistance at the adsorption part or the desorption part is increased, the driving net can be surely driven.

Abstract: PURPOSE:To make stability of resistance value good by obtaining excellency in resistance to oxidation at a high temperature, by a method wherein for a heating element for a thermal head, polysilicon is doped by phosphorus, and a concentration of phosphorus is made 5X10<20> to 1X10<22>. CONSTITUTION:A thermal head has an alumina substrate 5, a heat accumulation layer 4, a heating element 3, electrodes 2, 2', a protective layer 1, and is constructed by making a part 6 between the electrodes 2, 2' a heating part. Then, the heating element 3 is made of polysilicon doped by phosphorus, of which a concentration of phosphorus is adjusted to within a range of 5X10<20> to 1X10<22> (1/cm<2>). Consequently, since a high heat resistant heating element 3 having excellence in resistance to oxidation can be obtained, a high speed and high thermal efficient thermal heat can be prepared. Further, even though increase of a phosphorus concentration, which cause decrease of a resistant value, occurs, a stable characteristic of little variation in the resistance value can be obtained since a range of little variation in specific resistance is used.

Abstract: PURPOSE:To prevent a lateral force from excessive reduction due to the excessive braking without previously restraining a braking force. CONSTITUTION:An anti-lock brake control system is provided with an ABS controller 10 for controlling brake fluid pressure for left, right, front and rear wheels 11, 12, 13 and 14 on the basis of slip factor or the like and a 4WS controller 3 for determining a desired rear wheel steering angle on the basis of a front wheel steering angle, vehicle speed, etc., and controlling the current to a motor 4 to make the rear wheel steering angle coincide with the desired steering angle. The 4WS controller 3 monitors a value of the current to the motor 4 in the constant rear wheel steering angle to output a pressure reduction requesting signal to the ABS controller 10 in the abrupt reduction of the current value and cancel the output of the pressure reduction requesting signal in a change in the rear wheel steering angle or return of the current value to the original one. On the other hand, the ABS controller 10 reduces brake fluid pressure upon receiving the pressure reduction requesting signal under a braking condition and somewhat large slip factor and stops the reduction of brake fluid pressure by canceling the sending of the pressure reduction requesting signal.
