摘要:
The present invention relates to a blood vessel wall analyzing apparatus provided with a structure enabling accurate measurement of plaque components in a blood vessel wall in a state that reduces the burden on a patient. In the blood vessel wall analyzing apparatus (1), measurement light is illuminated onto a measured portion within a blood vessel such as a carotid artery (C) from a light illuminating unit (30) provided outside the blood vessel, while light from the measured portion is detected in a light receiving unit (40) provided outside the blood vessel. Thus, since the status of the blood vessel wall can be analyzed without inserting an apparatus involved in measurement into the blood vessel, the burden on the patient is reduced during measurement. In addition, as a result of carrying out measurement using near infrared light (a light component in the wavelength range of 780 nm to 2750 nm) that exhibits characteristics that differ according to the compositions of substances such as plaque adhered within the blood vessel, analysis can be carried out that distinguish compositions such as plaque using an analyzing apparatus provided outside the blood vessel.

The present invention relates to a blood vessel inner wall analyzing apparatus provided with a structure for more accurately analyzing components of substances adhered to the inner walls of blood vessels. A blood vessel inner wall analyzing apparatus (1) is provided with illuminating means, detecting means and analyzing means. The illuminating means illuminates a light component in a measurement wavelength range of 1957 nm to 2713 nm onto a measured position from an end surface (30b) of a light illuminating fiber (30) inserted into a carotid artery (C). The detecting means receives a light component from a measured position through an end surface (40a) of a light receiving fiber (40) within the carotid artery (C). The light component to be detected is a light component in a detection wavelength range which extends 15 nm on both short and long sides of the selected center wavelength, with each one or more center wavelengths being selected from a wavelength group comprised of specific wavelengths respectively in the measurement wavelength range. The analyzing means analyzes for the presence or absence of substances differing from blood by using intensity information on the detected light component.

In a liquid crystal display device having a front window, light from a backlight is prevented from leaking through chamfered edges of the front window. An upper polarizing plate is formed on an opposing substrate and a light shielding material is formed abutting on an outer edge of the upper polarizing plate. Edges of the upper polarizing plate are located inward of edges of the front window. The upper polarizing plate and the front window are bonded with a boding material including an ultraviolet curable resin. The ultraviolet curable resin also lies over the light shielding material. Chamfers are formed in the front window and the ultraviolet curable resin does not adhere to the chamfers of the front window. By this structure, light from the backlight is prevented from entering the internal part of the front window through the chamfers of the front window and light leakage is prevented.

Deaeration of the high pressure oil chamber of a hydraulic tensioner takes place though a helical orifice formed by opposed flanks of the threads of a threaded hole in the tensioner housing and the threads of a screw inserted into the hole. The opposed flanks are maintained in spaced relationship by a force exerted by a spring washer disposed between the head of the screw and a surface of the tensioner housing surrounding the opening of the threaded hole. The flank of the thread of the hole that forms part of the boundary of the helical orifice can have a concave curvature in order to increase the aperture of the air flow path. A groove in the surface surrounding the opening of the threaded hole prevents the washer from sealing off the flow of air. This groove is disposed with its exit end at a level above its entry end.

There is provided a ratchet-type tensioner whose spring stopping washer for seating a ratchet biasing spring is rigidly and readily assembled to a ratchet-receiving hole so as not to fall out of the ratchet-receiving hole and which reduces flapping noise and prevents seizure of the plunger by securely and stably operating a ratchet mechanism in operating an engine. The ratchet-type tensioner 100 is arranged so that the spring stopping washer has a C-ring anchored in the rear-end area of the ratchet-receiving hole by fitting in a diameter-reduced state and by enlarging its diameter within an anchoring circumferential groove of the ratchet-receiving hole and a spring stopping piece extended from the C-ring to a ring center area to seat the ratchet biasing spring.

A ratchet-type tensioner capable of restricting setback of a plunger includes a ratchet mechanism that allows setback of the plunger by sliding a ratchet element in a disengaging direction to disengage ratchet teeth from rack teeth when a reaction force acts on the plunger as a result of excessive chain tension. The ratchet element is slidable in a ratchet-receiving hole, and an inclination suppressing structure that prevents the ratchet element from becoming skewed in the ratchet receiving hole to an extent such that its forward end contacts one side of the hole while its rearward end contacts the opposite sides of the hole.

The problem to be solved by the present invention is to provide a method for continuously and effectively producing an aliphatic polyester having an increased molecular weight which prevents evaporation of diisocyanate at the step of mixing the diisocyanate with the aliphatic polyester prepolymer in a molten state at a temperature not lower than the melting point of the prepolymer and enables uniform mixing of the diisocyanate with the aliphatic polyester prepolymer. In order to solve this problem, the present invention provides a method for producing an aliphatic polyester having an increased molecular weight comprising the steps of: (i) quantitatively injecting a diisocyanate into an aliphatic polyester prepolymer which has a number average molecular weight of 5000 or higher and has terminal hydroxyl groups and in which at least one acid component is a succinic acid compound, in a molten state at a temperature not lower than the melting point thereof, wherein the amount of diisocyanate is equivalent to between one tenth and two times the amount of the hydroxyl groups in the aliphatic polyester prepolymer, (ii) quantitatively and continuously mixing the diisocyanate-containing aliphatic polyester prepolymer obtained at step (i) by a static mixer, discharging same from the static mixer, and then supplying same to a coupling reaction tank, and (iii) reacting the aliphatic polyester prepolymer with the diisocyanate in the coupling reaction tank.
