    摘要： A board-mounted electrical connector makes it possible to sufficiently reduce stress in the connector housing caused by threaded attachment fixtures. Metal fixtures (30) for mounting of the electrical connector to a circuit board are arranged in end sections (27) of a thin and long housing (20). The metal fixtures (30) are secured in oblong openings (72) provided in end portions (46) of a metal shield (40) attached to an outside surface of the housing (20) so that they cannot rotate inside the openings. The metal fixtures (30) are retained in the openings by means of integral resilient retaining members (71) of the shield (40) being disposed in grooves (36) in the metal fixtures (30).

    摘要： An instrument having a front cover which can be easily cleaned when dust and dirt adhere on the front surface of the instrument cover. The front cover has a toothed surface for reducing light reflection at the central portion of the front cover, and a smoothed fringe surface around the toothed surface which has an area for accepting a piece of wiping cloth. When dust and dirt accumulate in the toothed surface, they can be wiped off by a piece of cloth easily.

    摘要： An ultrasonic probe system is disclosed, which is designed to allow connection of a DC power supply capable of applying a voltage higher than the coercive electric field of each of a plurality of piezoelectric layers thereto, and includes a polarization turn over circuit means for, when the DC power supply is driven, turning over the polarity of the DC power supply so as to direct electric fields of every two adjacent layers constituting the piezoelectric layers in substantially opposite directions or electric fields of all the layers in the same direction. When the polarization turn over circuit means turns over the polarity of a voltage to be applied to direct electric fields of every two adjacent layers of the piezoelectric layers in substantially opposite directions or electric fields of all the layers in the same direction, the polarization turn over circuit means performs control to apply the voltage during a blanking time of an operating time of the system, thereby performing conversion of a resonance frequency, and selectively generating ultrasonic waves having a plurality of different frequencies.

    摘要： A Y-type zeolite having a SiO.sub.2 /Al.sub.2 O.sub.3 ratio of at least about 4 is produced by the following process. In the first step of the process, an aqueous alkali silicate solution and an aqueous alkali aluminate solution are mixed together in the presence of an alkali in an amount such that the ratio of M.sub.2 O(M: an alkali metal)/Al.sub.2 O.sub.3, present in the mixed solution, is at least about 5 by mole, followed by forming a gel in the mixed solution and, then, separating the gel therefrom. In the second step, the separated gel is incorporated in an aqueous alkali silicate solution or an aqueous alkali silicate-alkali mixed solution to obtain a slurry and, then, a Y-type zeolite crystal is formed in the slurry.

    摘要： Zeolite substantially free from a free alkali ingredient is produced by a process wherein a silica source and an alumina source is reacted in an aqueous reaction medium containing an excessive amount of an alkali ingredient to form zeolite, followed by separating the so formed zeolite from the aqueous alkaline reaction medium or from an aqueous medium in which the zeolite, after being separated from the aqueous alkaline reaction medium, has been slurried. The separation of the zeolite from the aqueous alkaline reaction medium or from the aqueous medium, in which the zeolite has been slurried after being separated from the aqueous alkaline reaction medium, is effected in the added presence of an alkali metal or alkaline earth metal salt of aluminic acid.
