IPC: C04B28/04
Filed: 1990-03-30
Abstract: PURPOSE:To easily obtain a kneaded material in which the desired composition is held by applying dry blending to materials other than aggregate and water in the compositions of concrete and mortar to form a cement composition and supplying this cement composition to a kneading stage by means of a concrete mixer. CONSTITUTION:A cement composition is obtained by subjecting 2-25 pts.wt. pozzolan powder, 0.05-0.20 pts.wt. short fiber of synthetic fiber, and 0.03-0.40 pts.wt. powder of synthetic resin swelling and dispersing in water to dry blending with 100 pts.wt. normal or high early strength portland cement. By using this cement composition, shotcrete in which the desired composition is precisely kept can be easily obtained at the time of preparing the shotcrete in the job site, without causing loss of the short fiber as reinforcement. Accordingly, the occurrence of splash loss, crack, sagging, etc., at the time of spraying can be prevented, and also cracking due to shrinkage in the course of hardening and after hardening can be reduced.

Title: Method for adjusting and fixing optical circuit parts
Inventor: KATO KUNIHARU
IPC: G02B6/24
Filed: 1987-04-03
Abstract: PURPOSE:To decrease a coupling loss between two elements which require alignment to each other without increase the accuracy of parts by rotating one of the above-mentioned two elements on a positioning jig to minimize the angular mis-alignment of the optical axes between the two elements. CONSTITUTION:Optical fiber collimators 5a, 5b are respectively disposed in V-shaped guide grooves 10a, 10b on the positioning jig 9. A glass block 7 is so disposed as to be butted against projections 11. The collimator 5b is rotated in this state by phi around the Z axis. The angular mis-alignment DELTAPY decreases to zero and the angular mis-alignment between the incident light rays BC and BX on the collimator 5a attains DELTAtheta' when the exit light BP of the collimator 5b comes to the position of the ray BX on the X-Z plane. Since the axial mis- alignment DELTAXC does not change at this time, the coupling loss between the collimators 5a, 5b facing each other is decreased if the conditions DELTAtheta'<DELTAtheta (DELTAtheta is the angular mis-alignment between the rays BP and BC) hold. The angular mis-alignment of the optical axes between the collimators 5a and 5b is minimized according to this method and, therefore, there is no need for enhancing the accuracy of the parts.

Abstract: PURPOSE:To facilitate synchronizing separation by clamping only the tip part of synchronism by using a clamping pulse and making composite video signals having the uneven tip of synchronism flat. CONSTITUTION:The tip of synchronizing signals of composite video signals in an output terminal and a voltage divided by resistances R7, R8 are compared by a differential amplifier of transistors Q3, Q4. When the voltage of the base of the transistor Q4 is higher, the transistor Q4 turns on and flows a collector current, and the collector voltage drops. Then, a transistor Q1 turns on, and flows a current through a resistance R1 and a capacitor C. Then, a voltage at a point A rises and a voltage of the terminal also rises. When a voltage of the terminal 2 exceeds the split voltage of resistances R7, R8, transistors Q4, Q1 turns off and a current i1 stops flowing, and a charge accumulated in the capacitor C is discharged by a current i2. By setting R1<<R2, i1<<i is applicable and clamping is made possible. A clamping pulse is applied to the base of a transistor Q5 and the differential amplifier is functioned only for the period.
