In a serial communication unit having a CRC calculator or in a single-chip micro-computer including the serial communication unit, the CRC calculator is operated in synchronism with a system clock which is different from and asynchronous with respect to a reception clock. As a result, the CRC calculation is prevented from being stopped by the interruption of the reception clock, or the CRC calculation by the software is unnecessitated, thereby improving the communication efficiency.

A nonlinear optical material is provided by mixing a polymer liquid crystal having a chiral center and a nonlinear optical compound. The polymer liquid crystal may be a ferroelectric polymer liquid crystal. The nonlinear optical material is preferably in the form of a solid solution. A nonlinear optical device is formed by orienting the nonlinear optical material to provide an optical member.

Disclosed are a hose fitting comprising the following and a process for manufacturing the same: A hose fitting body composed of a head portion with a through hole made in the center of a pair of flat surfaces thereof, a base portion, and a sleeve all of which are formed out of a test tube-shaped substance by a plastic deformation, and a nipple integrally fixed on the inner circumferential surface of the sleeve. The hose fitting of this invention provides the following advantages of offering easy work for the bending the base portion, offering readiness for securing a necessary cross-sectional area as the fluid delivery hole of the base portion even when the base portion is bent greatly, light-weighted construction having a uniform wall thickness and requiring less raw material cost, and fixing nipple on the sleeve inner circumferential surface in a fluid-tight manner without brazing or drive fitting the nipple.

Herein disclosed is a hose joint which comprises an outer tube having a threaded portion at one side of a flanged portion and a sleeved portion at the other side, and an inner tube arranged in the outer tube and having a nipple portion positioned in the sleeved portion and a tapered sealing portion for providing communication between the nipple portion and the threaded portion of the outer tube and for acting for a mating member to be jointed to the hose joint. Both the outer tube and the inner tube are made of a tubular material such that at least the flanged portion of the outer tube and the sealing portion of the inner tube are plastically deformed.

A composition for use in a chloride ion electrode is provided herein. This composition is made up of a mixture of an epoxy resin, a vinyl chloride resin, one or more solvents, a quaternary ammonium salt and hardening agents for setting said epoxy resin; wherein said epoxy resin and the vinyl chloride resin is used at a ratio of 8:1 to 1:2 by weight. The present invention also relates to a response membrane produced from said composition and a method for producing the response membrane by setting or hardening the aforementioned composition. When the response membrane is used in the chloride ion selective electrode, it is capable of measuring a sample containing blood or protein and by use of the response membrane, it is possible to selectively determine chloride ions in a sample with a high degree of accuracy.

The present invention concerns an apparatus for forming into shape one end portion of a rod-like metallic work such as a pipe. The apparatus comprising a holding member to hold the work, a split die composed of at least two movable die members, and a pressure die. Both the split die and the pressure die have engaging portions which move the split die in directions perpendicular to the axial direction with movement of the pressure die in the axial direction. The split die clamps the outer surface of the end portion of the work. Further the pressure die moves toward the holding member and forms the end portion of the work into shape between the split die and the pressure die. So, as set forth hereinabove, both clamping for the split die and forming for the work can be done by the one stroke of the pressure die. Thus, it is not necessary to provide two drive sources for moving the split die and for moving the pressure die, and therefore it is possible to attain simplification of equipment.
