Abstract: A method and circuitry for testing in situ the compo­nents mounted on a circuit board. First, a component is removed from the board. A testing circuit is then in­stalled in place of the removed component. The testing circuit allows test patterns to be applied to a selected component on the board from the board I/O pins. The selected component responses are collected by the testing circuit and applied to the board output pins. In this manner, individual components on the board can be tested in situ from pins on the board.

Abstract: An automotive refrigerant compressor (10) according to the present invention comprises a compressor housing (11, 21) that includes at least one bracket (13a-13h, 23a-23d). The bracket (13a-13h, 23a-23d) has a hole (131a-131h, 231a) through which a fastening member, such as a bolt (14) for example, penetrates. A vibroisolating member (15) is provided that includes a cylindrical portion (15a) and an annular flange portion (15b) radially extending from one end of the cylindrical por­tion (15a). The cylindrical portion (15a) is firmly inserted into the hole (131a-131h, 231a) in the bracket (13a-13h, 23a-23d), with the flange portion (15b) disposed at an outer surface of the bracket (13a-13h, 23a-23d). The flange portion (15b) includes a pair of protrusions (15c) on oppos­ing sides of the flange portion (15b). The protrusions (15c) are inwardly bent at the base thereof so as to fit along a side surface of the bracket (13a-13h, 23a-23d) when the cylindrical portion (15a) of the vibroisolating member (15) is inserted into the hole (131a-131h, 231a). In accordance with this construction, the refrigerant com­pressor (10) can be easily mounted within the engine compartment of a motor vehicle without having to be concerned with the conventional problem of slipping vibroisolating members (15). Furthermore, when a so-called vibroisolating steel member (150) is used as the vibroisolating member (15) of the present invention, separation of the vibroisolating member's rubber plates (152) from the steel plates (151) can be prevented with­out having to be concerned with the amount of torque used to tighten the fastening bolt.

Abstract: This invention uses a new method of producing ionic metallocene compounds. These compounds are useful as catalysts for polymerization of olefins, primarily propylene. This method uses an ionizing agent which ionizes the neutral metallocene compound. The ionizing ionic compound does not contain an active proton and contains a carbonium, oxonium or sulfonium cation. The anion of the ionizing ionic compound is not coordinated or is only loosely coordinated to the metallocene cation and is chemically unreactive with the metallocene cation. One such compound is triphenylcarbenium tetrakis(pentafluorophenyl)boronate. 
     The process of making catalysts with this invention produces catalysts having high activity and does not produce by-products which can inhibit catalyst activity. This new synthesis is a clean reaction which does not produce a Lewis base. The process generates active catalysts by removing a methyl anion from a group IV metallocene derivative.

Abstract: Highly directional optical systems, particularly for use in detecting light-absorption distribution in a living body (21/170), are disclosed. 
     A laser light source (20/181) applies light to a specimen (21/170), and a light-receiving element (P ,P /100) divides a light propogation region into a plurality of subregions, each subregion being limited within a minimum spatial resolution unit where an interference occurs between discrete points, and a 0-order diffraction pattern of a Fraunhofer diffraction image is detected (at 23/180). If a convex lens (25/180) and either a pinhole (P ) or an optical fiber (30) which is disposed on a focal plane of the convex lens are employed, and the diameter of the pinhole or the core diameter of the optical fiber is set to be not greater than the first dark ring (A) of a Fraunhofer diffraction image produced by the convex lens, it is possible to take out the greater part of the energy of a plane wave component that enters the lens from a pre-determined direction and to remove other components from different directions, i.e., scattering component. If a plurality of optical systems of this type are bundled together (100), only a plane wave with a one- or two-dimensional intensity distribution can be taken out with high brightness and high resolving power. Since the scattering component attenuates and only an information light component carried by the plane wave can be detected, it is possible to obtain information about an absorber (170) even when the scattering component is greater than the information light component as in the case of light transmitted by a human body. Thus, it is possible to obtain great advantages in application to optical CT or the like.
