  • Publication number: 20220093775
    Abstract: At least one transistor is arranged on a substrate. A collector layer and a base layer of the transistor compose a collector mesa having a substantially mesa shape and the collector mesa has side faces tilting with respect to the substrate so that the dimension of a top face in a first direction of a plane of the substrate is smaller than the dimension of a bottom face therein. A first insulating film covering the transistor is arranged on the substrate. A first-layer emitter line that extends from an area overlapped with the top face of the collector mesa to areas overlapped with at least part of the tilting side faces of the collector mesa in a plan view is arranged on the first insulating film. A second-layer emitter line and an emitter bump are arranged on the first-layer emitter line.

  • Patent number: 11278900
    Abstract: Microperturbation fluidic assembly systems and methods are provided for the fabrication of emissive panels. The method provides an emissive substrate with a top surface patterned to form an array of wells. A liquid suspension is formed over the emissive substrate top surface, comprising a first liquid and emissive elements. Using an array of micropores, a perturbation medium, which optionally includes emissive elements, is injected into the liquid suspension. The perturbation medium may be the first liquid, a second liquid, or a gas. A laminar flow is created in the liquid suspension along the top surface of the emissive substrate in response to the perturbation medium, and emissive elements are captured in the wells. The ejection of the perturbation medium can also be used to control the thickness of the liquid suspension overlying the top surface of the emissive substrate.

  • Publication number: 20220080918
    Abstract: An airbag apparatus attachment mechanism includes a holder, a supporting member, an urging member, and a functional member. The holder is fastened to a metal core with a fastening member. The supporting member protrudes further forward than an airbag apparatus and is inserted into the holder. The urging member urges the airbag apparatus rearward. The functional member is attached to a part of the supporting member that is inserted in the holder. The functional member includes a spring portion that is thinner than a gap between the supporting member and the holder. The spring portion is disposed in the gap. The functional member is configured such that the spring portion is elastically deformed in a radial direction of the supporting member due to vibration of the airbag apparatus, thereby suppressing the vibration.

  • Patent number: 11240912
    Abstract: A cavity elongated in one direction is formed in a protective film covering the conductive pattern of the topmost conductive layer of a multilayer wiring substrate. The cavity exposes part of the conductive pattern. A first via-conductor extends downward from the conductive pattern of the topmost conductive layer at least until that of a second conductive layer. Second via-conductors extend downward from the conductive pattern of the second or third conductive layer at least until that of a conductive layer one below. As viewed from above, the first via-conductor and the cavity partially overlap each other. At least two second via-conductors are disposed to sandwich the cavity therebetween. The difference between the smallest gap between the cavity and the second via-conductor at one side and that between the cavity and the second via-conductor at the other side is smaller than the smallest gap between the cavity and the second via-conductors.

  • Publication number: 20210404552
    Abstract: A transmission system configured to perform a gear change based on a shift operation by an operator is provided, which includes a power transmission system including a transmission and configured to transmit an engine driving force to wheels, a shift operation detecting module, and a transmission controlling module adapted to be executable of a manual rotation synchronizing mode having first and second steps.

In the second step, when a second shift operation is detected, the transmission controlling module sends a control signal to the connecting-and-disconnecting mechanism to resume the transmission of the driving force while the transmission is switched to the lower-speed side.
