Title: Extruder for multi-layer parison
Inventor: FUKUHARA KEIJI
IPC: B29C48/92
Filed: 1989-08-25
Abstract: PURPOSE:To accurately control the extrusion of a multi-layer parison by selectively detecting infrared rays radiated from the inner layer that has the highest plasticizing temperature among extruded inner layers and identifying the existing conditions of the inner layers on the basis of a detected signal. CONSTITUTION:The temperature of HDPE (high-density polyethylene) shows 190 to 210 deg.C immediately after a parison 50 is extruded, while PA has a temperature of 230 to 250 deg.C, and an adhesive layer has a temperature therebetween. Infrared rays transmitted through the HDPE to come out to the external side are separated at 180 deg.C, (200 deg.C) 220 deg.C and selectively sensed by using a high-sensitive infrared ray sensor (in this case, a CCD camera 61) with an infrared ray filter 61A that permits the infrared rays alone to pass therethrough. Upon comparison of each measured output with normal patterns stored in a normal pattern storage unit 64 by means of an identifier 63 via an image processing unit 62, whether the difference i.e. DEV between the measured output thus compared and a preset value is within a predetermined range is determined. In the case of YES, an YES display unit 65 displays YES, while in the case of NO, its DEV signal is sent to an inner-layer ring parison control circuit 72. The control circuit 72 sends a correction output signal corresponding to the DEV signal to servo valves 31, 32, and a controlled hydraulic pressure is sent to each of hydraulic cylinders 19, 20 from a hydraulic source 30.

Abstract: PROBLEM TO BE SOLVED: To actualize a selector antenna system which satisfies necessary antenna characteristics, such as directivity, a half-value angle, a tilt angle and the like, by optionally setting the opening angles and corner lengths of reflectors. SOLUTION: A selector unit, consisting of an antenna element 3 and a reflector 2 and a selector unit consisting of an antenna element 3 and a reflector 2b are arranged annularly in turn and the needed position of the fan of the reflector 2b, is offset radially outward to make an opening angle α1 and corner length of the reflector 2a different from an opening angle α2 and a corner length of the reflector 2b. Namely, the needed positions of the fans of the reflectors are arranged outside to increase the opening angles of the reflectors according to the extent of outward offsetting and shorten the corner lengths, thereby making the total opening angle of the reflectors larger than 360 deg.. Furthermore, circuit components accompanying the selector antenna are arranged in a space 4 formed by this arrangement.

IPC: F01N13/02
Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To improve the NOX cleaning capacity of an NOX absorption-reduction catalyst. SOLUTION: A converter 70 incorporating an NOX absorption-reduction catalyst is arranged in an exhaust gas passage 2 of an engine 1. In addition to the NOX absorption-reduction catalyst, an oxygen storage component which absorbs oxygen in exhaust gas when the exhaust air fuel ratio is lean and which releases the absorbed oxygen when the air fuel ratio of inflow exhaust gas is rich, is supported in the first half part (inlet part) of a carrier for the NOX absorption-reduction catalyst in the converter. After the engine 1 is operated at lean air fuel ratio for the NOX absorption-reduction catalyst to absorb NOX, the engine is operated at rich air fuel ratio for NOX to be released from the NOX absorption-reduction catalyst to reduce and clean the catalyst.  Then, oxygen is released from the oxygen storage component supported in the first half of the carrier to react with H2, CO components and the like, and the temperature of the NOX absorption-reduction catalyst rises by the heat of reaction. Thus, activity of the catalyst is increased to improve the NOX cleaning capacity of the NOX absorption-reduction catalyst.

IPC: C22C19/03
Filed: 1984-10-23
Abstract: PURPOSE:To obtain powder for powder metallurgy from which a shape memory alloy having high density and large fatigue resistance is obtd. by subjecting an Ni-Ti alloy for shape memory to a soln. heat treatment then to quick cooling and pulverizing the hardened alloy. CONSTITUTION:The NiTi alloy having an equal atomic ratio or the extremely proximate thereto constitutes the alloy having about 600-700Hv hardness when the alloy is quickly cooled from the high and uniform temp. range of the TiNi solid soln. The hardened TiNi alloy is pulverized and the powder having the prescribed grain size is obtd. The powder has the above-mentioned hardness and is extremely suitable for pulverization and therefore all pulverizing methods which are usually used can be adopted. The liquid phase sintering by the melt of Ti2Ni arises if the powder is adjusted to the shape memory alloy by a powder metallurgical method and therefore the generation of holes occurring in the diffusion rate of Ti and Ni does not arise and even if the microdiffusion of Ti and Ni arises, the generation of holes does not arise. The above-mentioned hardness is removed in the sintering stage and the deformation ability which is the premise of the shape memory effect appears.
