  • Patent number: 5018269
    Abstract: In the wire press-installing apparatus of this invention, the ram is lowered onto the joint block to press wires into rows of receiver terminals that are erected at specified pitches on the joint block of a wiring harness. The joint block is intermittently fed by a distance equal to the pitch of the terminal rows and only the predetermined wires are selectively taken out and seated into the associated rows of receiver terminals. This prevents wrong wires from being seated in unintended terminals or the joint block from being fed by a wrong pitch. The apparatus has a wire misinstallation detection mechanism, which consists of wire guides mounted vertically slidable on the lower front and back side of the vertically movable wire press-installing blade through a resilient member.

  • Patent number: 4747666
    Abstract: Three stacks composed of high refractive index substance layers and low refractive index substance layers, which are alternately arranged, are formed on one side of a substrate. Of the three stacks, the central stack has a number of layers which are about half the number of all the layers and each individual layer is set so as to be a desired optical quarter-wave thickness. Two stacks are arranged on opposite sides of said central stack, which stacks each have a number of layers of about 1/4 times the number of all the layers and which are set so as to be different in optical thickness from each other and different from the desired quarter wave optical thickness of the central stack layers, said stack combination being capable of easily producing a multi-layer interference filter having good spectrometic characteristics.

  • Patent number: 4734365
    Abstract: This invention relates to a process for liquefying starch. More particularly it relates to an appropriate process for liquefying starch by using a thermostable .alpha.-amylase which has an optimum working pH range in an acidic region and a low calcium requirement.This invention provides a process for liquefying starch by using a calcium-requiring, thermostable .alpha.-amylase which requires a calcium concentration of 10 .mu.m or below under a thermostable condition.In the process of the present invention, it is unnecessary to add a calcium salt in liquefying starch and the starch slurry can be reacted while remaining acidic without neutralization, so that the load at the desalting step of the product can be significantly relieved.
