  • Patent number: 11860110
    Abstract: To provide an article inspection apparatus capable of sensitively and stably detecting a change in a spectrum when an unspecified foreign substance is contained and determining a defective product. A transport unit that transports a tablet for inspection to an article inspection position, a light irradiation unit that irradiates the tablet transported to the article inspection position with light, a light detection unit that detects light transmitted through the tablet, and an article inspection unit that inspects a quality of the tablet based on spectral characteristics of the light detected by the light detection unit are provided, and the article inspection unit standardizes a measured value of a spectrum of the light detected by the light detection unit for each wavelength and determines whether the tablet is a normal product or a defective product based on a standardized value.

  • Patent number: 11171395
    Abstract: An object is to provide a transmission line having an air bridge structure in which grounding conductors of a transmission line are connected by wiring and which is stable in terms of mechanical strength by lowering an electrostatic capacitance in a region where the wirings connecting the central conductor and the grounding conductor intersect with each other. The transmission line includes a substrate, a first central conductor and a second central conductor that are formed on a surface of the substrate, a third central conductor that has a first erection portion and a second erection portion erected on the surface, and a first grounding conductor and a second grounding conductor. The transmission line further includes a third grounding conductor connecting the first grounding conductor and the second grounding conductor. The third central conductor and the third grounding conductor form an air bridge structure.

  • Patent number: 6442167
    Abstract: The present invention intends to realize highly reliable communications between a frame relay network and an ATM network by corresponding service classes decided in both networks to each other. In order to achieve the above object, the frame relay data communication apparatus of the present invention used to allow communications between the frame relay network and the ATM network is provided with a frame receiver unit for receiving frame data from the frame relay network; a cell assembly unit for assembling received frame data into ATM cells and transmitting assembled cells to the ATM network; and a controller for controlling both frame receiver unit and cell assembly unit so as to extract priority order information from received frame data and receive priority order information of data used in ATM networks from an ATM network and decide a service class of the received data to assemble the received frame data into cells according to the decided service class.

  • Patent number: 4972572
    Abstract: An IC sheet cutting press performs a series of press cutting operations to separate ICs from an IC sheet while feeding the IC sheet stepwise. In the IC sheet cutting press, a series of press molds and an IC feed mechanism are mounted on a common die set to constitute a single press mold unit. When a different type of IC sheet is to be machined, the entire press mold unit can be exchanged with another one, so that various adjustments, e.g., adjustment of arrangement intervals of the press molds or a feed interval of the IC sheet can be omitted, and the operating efficiency of the cutting press and hence the compatibility are improved.An IC sheet processing apparatus, in which the IC sheet cutting press described aboved is combined with an automatic IC sheet loading unit, an IC lead bending press, and an IC storage unit for storing ICs after the lead bending operation, allows automatic IC sheet processing including the cutting operation of ICs from the IC sheet over a long period to time.
