Title: Polyurethane thermoplastic elastomer film for seat suspension
Inventor: ABU-ISA ISMAT ALI
IPC: B60N2/90
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a polyurethane thermoplastic elastomer film suitably used for a seat suspension by forming polyurethane thermoplastic elastomer of straight chain polymer molecules containing polyol part segments alternate with polymer segments. SOLUTION: Polurethane thermoplastic elastomer consists of a block copolymer composed of solid and hard crystalline urethane block chemically bound to relatively soft amorphous block of polyether or polyester molecular units. The degree of elasticity of the thermoplastic elastomer depends on the mol ratio of soft segments to hard segments. When the ratio of the soft segments is high, more elastic behavior is generated in a polyurethane film. The polyurethane thermoplastic elastomer consists of polymer molecules chemically unbound to each other by cross-linking.

Title: Multiple liquid type etching method in gravure engraving
Inventor: KATSUTA TETSUROU
IPC: B41C1/00
Filed: 1981-05-28
Abstract: PURPOSE:To make the manufacture of a machine plate of stable quality with good  reproducibility without requiring skill by measuring the penetration time of resist by  inspecting liquid, and determining etching conditions prior to corrosion. CONSTITUTION:When conductive inspecting liquid SL is dropped onto the resist electrode 12, 14 positions on resist 10, these contact, and from the point when they drop,  potential VB from an electric power source VCC enters a comparator 16. Since this is  larger than threshold potential VTH, a counter 22 begins to move, and the liquid SL  penetrates through the resist and therefore the VB decreases gradually and stops decreasing at the point when it goes lower than the VTH, from which the penetration  time (t) can be measured. This is determined with respect to gradation partsI-IV.  The relation between cell setting volume V and the time t is determined from the relation between the volume V and positive concn. and the time (t), and the relation between the time and etching liquid penetration time. The combinations of various etching liquids to be used, the use sequence thereof and the time distribution of the use  can be derived by utilizing the curves thereof. The etching of the plate material entails  the determination of a total corrosion time and this is determined from about at least how mutch time T is required in order to obtain the volume V of the extreme  shadow part IV.

Abstract: PURPOSE:To contrive adequateness of traction control at the time of starting by independently estimating a friction coefficient respectively relating to right/ left drive wheels based on a relation between a preset engine speed and a road surface friction coefficient under a specified starting condition of a vehicle. CONSTITUTION:In a control unit 200, at the time of starting a vehicle, an engine speed, represented by a detection output signal Sn, is collated with a data map, determining a relation between an engine speed prestored in a built-in memory and a road surface friction coefficient, to individually estimate friction coefficients muR, muL of right/left rear wheels 20R, 20L at the time of starting. In the case of estimating the friction coefficient of only one of the right/left rear wheels, the control unit 200 estimates the coefficient with muX in a proportional relation to one of the estimated friction coefficients muR, muL. The value muX thus obtained is set to a value, for instance, 1.5 times one of the estimated road surface friction coefficients muR, muL. In this way, the estimated value is prevented from extremely separating.

Filed: 1987-04-03
Abstract: PURPOSE:To decrease the current consumption of an optical transmission circuit by adding an optical output intensity switching circuit to an optical transmission line in a portable terminal equipment having a space propagation type optical communication function. CONSTITUTION:A portable terminal equipment 1 having a switch 7 operated by a magnet 5 is set to a near end communication repeater 2 having the magnet 5.

In removing the equipment 1 from the repeater 2, the switch 7 is restored to the 'open' position and the current flowing to the light emitting diode 8 is the sum flowing to the path of the resistor 11 and the path of the TR 10 and the resistor 12. Thus, the switch 7 applies switching of the optical output intensity of the light emitting diode 8. Thus, the nearby communication is applied with required minimum power.

Title: Weight type torque converter
Inventor: IEI TOMIYOSHI
IPC: F16H35/00
Filed: 1993-04-09
Abstract: PURPOSE:To reduce the variation rate of instantaneous torque and oscillation by feeding back a difference between input and output shaft speeds due to variation of load on an output shaft to a hollow shaft, and converting and transmitting a rotating torque caused by a centrifugal force which is generated by multiple weights fitted closely on the hollow shaft to the output shaft.

Then the rotation is reversed by external gears 13 and 14, and transmitted as a clockwise rotating torque to an output shaft; And a load on the output shaft 2 side is increased and, as the speed of the output shaft 2 is lowered, the speed of the sun gear 17 and hollow shaft 1'. is increased by feedback of the differential gear mechanism (a) to increase an output shaft average torque T2. Thus the variation rate of instantaneous torque and oscillation can be reduced.
