Title: Railroad sleeper made of foaming polymerization product material
Inventor: KIKUCHI ISAO
IPC: E01B3/44
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To obviate reinforcement of fiber, and to reduce a cost by polymerizing/forming polyisocyanate mainly composed of an isocyanate terminal prepolymer and polyol mainly composed of specific polyether polyol. SOLUTION: Polyol reacting with a prepolymer is mainly composed of polyether polyol not less than four functional groups of 300 to 500 of hydroxyl value. In this case, a foaming agent is selected from water, hydrocarbon and halogenated hydrocarbon, and diol having molecular weight not more than 150 is suitable as polyol to be mixed. The NCO content of this prepolymer is set to 5 to 35%, and flexibility and flexural strength are adapted to a sleeper from a high polymer structure by polymerization. The polyol not less than four functional groups is used, bending strain of a polymer is suitable, and pull-out strength of an anchor nut is excellent. Thus, decay is prevented since this sleeper is made of plastic, the sleeper is close to concrete is strength, and residual strain by a compressive load such as a railway rolling stock can be reduced more than a wooden sleeper.

Filed: 1992-03-13
Abstract: PURPOSE:To provide using a simple method a denture material having dentures embedded in unhardened or half-hardened denture bed material and conforming well to a model of a mouth by fabricating the denture material of the upper jaw while dividing the material into a palate portion and other portions. CONSTITUTION:Denture material having dentures arranged in advance on unhardened or half-hardened bed material is put directly on a model of a mouth and is stuck in the model to fabricate bedded dentures. In order to correspond to various mouth configurations, the denture material for the upper jaw is divided into a palate portion and other portions. All kinds of mouth configurations can thus be dealt with by simply preparing several kinds of size of dentures to be arranged. Regarding the characteristics of the dentures fabricated, such a method can be employed whereby after the palate is stuck other denture bed portions are stuck, so controllability of the thickness of the denture bed is increased and the rate at which the dentures fabricated shrink as they stick to one another is reduced, so that the conformity of the dentures is enhanced.

Title: Hydraulic ram
Inventor: YAMAMOTO SHIZUO
IPC: F04F7/02
Filed: 1985-05-20
Abstract: PURPOSE:To prevent the defect, abrasion and breakage of each member by using, as water pumping-up valve, an elastic member whose one edge is fixed onto the valve seat part of a valve body. CONSTITUTION:When the pressure in a valve chamber 9 increases, the water stream passes through a water pumping-up hole 11' as shown by W, and pushes up a valve body 14. Though said valve body 14 is fixed at one edge by a fixing member 14a, the valve body 14 is deformed, since it is made of elastic material, and the valve body 14 is pushed upwardly, having one fixed edge as fulcrum, and a water pumping-up valve is opened. When the pressure in the valve chamber 2 lowers, the valve body 14 is lowered by he elastic force of the valve body 14, and the water pumping-up hole 11' is closed, and the water pumping-up valve is closed. With such constitution, the valve is freely opened and closed according to the variation of the water stream, and the breakage or abrasion of a bearing and valve shaft in the conventional can be avoided.

Title: Auto-zero intergrating device
Inventor: SHINODA YASUO
IPC: G06G7/186
Filed: 1985-05-17
Abstract: PURPOSE:To eliminate automatically an error output by holding the input offset voltage of an operational amplifier while the switch of an integrating capacitor is kept on and applying the held voltage to the non-reverse input terminal of the operational amplifire in the adverse polarity when said switch is turned off. CONSTITUTION:The both ends of an integrating capacitor C1 are short-circuited by a switch SW4 is a reset auto-zero mode and the negative feedback is applied to an operational amplifier OP1. Thus the input offset voltage -VOS of the OP1 is kept at a point (a). Then switches SW1 and SW2 are set at a contact I in an integration mode with switches SW3 and SW4 opened respectively. Thus an auto-zero capacitor C2 is connected adversely between the non-reverse input terminal of the OP1 and an earth line. Then the voltage held by the C2 is applied in the adverse polarity to the non-reverse input terminal of the OP1. Thus the input offset voltage of the OP1 is cancelled and the potential at the point (a) is equal to the earth potential. In such a way, an error output is eliminated automatically and an integration output is obtained with high accuracy.
