Title: Multi-contact terminal
Inventor: IWATOMO YOSHIHIRO
IPC: H01R13/11
Filed: 1994-04-22
Abstract: PURPOSE:To greatly enhance the contact reliability of a multi-contact terminal compared with fork type two-contact terminals by enabling the number of contact points to a mating terminal to be increased by one although the multi- contact terminal can be manufactured by the same manufacturing man-hour as for fork type two-contact terminals. CONSTITUTION:When a cylindrical mating terminal is fitted into first to third armatures, 2, 3, 5, respectively, the inner surface 9 of the mating terminal makes contact with the contact 36 of the second armature 3, the contact 26 of the first armature 2, and the contact 56 of the third armature 5 in sequence because of a level difference between the respective terminals 26, 36, 56 of the armatures 2, 3, 5. Therefore, the mating terminal and the contacts 26, 36, 56 are restrained from wearing out, and this contributes to enhancing longevity. This multi-contact terminal enables a cylindrical battery electrode in particular to be used as a mating terminal, in which case the wide portions 25, 35, 56 of the three armatures 2, 3, 5 are guided into e.g. longitudinal slits 86... of a shell type cover 85.

Title: Cement composition for high strength and high fluidity concrete
Inventor: ISOHATA TATSUO
IPC: C04B7/02
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a concrete having high fluidity and low viscosity in a low water to cement ratio and exhibiting high strength even if it receives heat history by specifying the ratio of Al2 O3 to Fe2 O3 in a cement clinker and the 2CaO.SiO2 content of the clinker. SOLUTION: The ratio of Al2 O3 to Fe2 O3 (IM) in the cement clinker is 0.05-0.62 and the 2CaO.SiO2 (C2 S) content of the clinker is 35-65 wt.%. When IM is <=0.62, an interstitial material in the case of calculation by the Bogue's equations is only a ferrite and the formation of C3 A is prevented on calculation. The C3 A having high hydration reactivity, generating a large quantity of heat by hydration and having large self-shrinkage can be made absent and the improvement of fluidity and the reduction of self-shrinkage are enabled. The lower limit of IM is 0.05 from the viewpoint of the compressive strength and elongation of mortar. In the case of <35 wt.% C2 S content, the amt. of C3 S increases, heat generation increases and strength exhibiting property deteriorates. In the case of >65 wt.% C2 S content, strength exhibiting rate decreases.

Abstract: PURPOSE:To suppress the unevenness of the emission amount at a minimum amount by forming a field emission cold cathode element with an electrode having a sharp tip, an insulating layer, and a control electrode, and forming the periphery of the opening of the control electrode thicker than the parts other than the periphery part. CONSTITUTION:At the periphery of an electrode 2, both an insulator layer 3 and a gate layer 4 are removed, and an opening is formed. A gate electrode 6 is formed of a gate layer 4 and a gate opening periphery 5, and the periphery 5 is formed thicker than the other parts. In a normal operation, a positive voltage of several dozens V is applied to the gate electrode 6 to an emitter 2 at the potential same as a substrate 1. Since the tip of the emitter 2 is formed extremely sharp, and the tip of the emitter 2 and the gate electrode 6 are positioned extremely close, a strong electric field is applied to the tip of the emitter 2, and electrons are emitted from the tip. A minute cold electrode is composed of a single emitter and the opening of the electrode 6 around the emitter, and a single minute cold cathode or a collection of plural minute cold cathodes makes a cold cathode.

Filed: 1981-06-04
Abstract: PURPOSE:To enable measurement of insulation resistance at a high efficiency in an electric circuit large in the floating earth capacity by connecting a current transformer and an oscillation transformer pierced by a ground wire of a transformer with a loop wire containing a capacitor. CONSTITUTION:An oscillation transformer OT for oscillating a low frequency voltage as measuring signal or the core of a transformer to which a low frequency is applied is pierced by the earth line of a transformer T through which a low frequency voltage is applied to electric circuits 1 and 2. A leakage current of a low frequency component fed back to the earth line is detected with a zero phase current transformer ZCT whereby the insulation resistance of the electric circuits 1 and 2 is measured by use of an effective component in the leakage current iG. In this case, the current transformer ZCT and the oscillation transformer OT are connected with a loop line CL having a capacitor connected thereto while the line CL pierces the transformer OT in the same direction as the line EL and the current transformer ZCT in the opposite phase. This can suppress a reactive component due to a floating earth capacity in the current iG.
