Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To minimize the influence of contact even when two members collide or interfere each other by detecting the approach of 1st and 2nd members and outputting a signal. SOLUTION: When 1st and 2nd members P1 and P2 approach more than a fixed level, the light beam of photosensor 107 is shielded by a light shielding board 108.

Filed: 1994-12-26
Abstract: PURPOSE: To eliminate or reduce current or voltage allowed to flow in a damping capacitance of a piezoelectric vibrator and a dielectric loss component thereof and obtain high sensitive output in a detection circuit for detecting vibration output from the piezoelectric vibrator. CONSTITUTION: Electric power is given to a drive means from an alternating drive power source 21, and a resilient body such as a vibration type gyroscope is driven. The vibration of the resilient body deformed by Corioli's force or the like is detected by a piezoelectric vibrator, but a reference element formed of the same piezoelectric material as the piezoelectric vibrator is connected to one electrode of the piezoelectric vibrator in series, voltage applied to the reference element from a path L2 is taken out, and amplified by an amplifier 23. The voltage amplified from the detection voltage of an output path L1 is decreased by a differential circuit 24.  The damping capacitance of the piezoelectric vibrator and a dielectric loss component thereof are thereby equivalently reduced by the capacitance and a resistant component of the reference element, and high sensitive vibration detection can be performed.

IPC: C04B28/02
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To improve both the workability and the durability while suppressing an alkali aggregate reaction by combining a calcium type zeolite with gypsum. SOLUTION: This additive is obtained by adding gypsum in an amount so as to provide the amount of the added calcium zeolite within the range of <10wt.% based on the sum of the calcium type zeolite and a cement within the range of <=20.0wt.% ratio of the amount of the added calcium type zeolite based on a binder (cement and an admixture) to the calcium type synthetic zeolite having <=7.0wt.% content of an alkali metallic component expressed in terms of anhydrides as Na2 O equiv. and 0.5-4.5μm average grain diameter. Thereby, ettringite is produced by a reaction of alumina in the zeolite with the gypsum to relax the shrinkage of a mortar or a concrete. As a result, cracking hardly occurs. Early deterioration due to an alkali aggregate reaction or salt damage, etc., is hardly caused.
