Title: Detection of correct electrodeposition of tin plating
Inventor: SAIJIYOU KINJI
IPC: C25D21/12
Filed: 1982-06-21
Abstract: PURPOSE:To detect adeguately the deposition condition of an electrodeposited tin crystal, by irradiating a characteristic X-rays to the surface of the tin plating layer on a band steel, detecting the fiffracted rays from the correctly bright deposited tin crystal and the non-brightly deposited tin crystal and determining the intensity ratio thereof. CONSTITUTION:A characteristic X-rays of a single color such as CuKalpha rays is irradiated onto the surface of a band steel which is electroplated with tin in such a way that the incident angle is made equal to the diffraction angle. The diffractd rays on the respective planes are determined according to the orientation of the tin crystals in parallel with the band steel, and the diffracted rays of the high scale of integration which is discriminated to be correct electrodeposition by naked eyes and the diffracted ray which has a high scale of integration in the electrodeposited tin crystal with defective brightness and differing in the crystal orientation are selected. The diffraction angles of these two rays or above are detected with a detector, and the intensities of the respective diffracted rays are measured. The measured values are conducted to an operation processor, which calculates intensity ratios. The electrodeposition condition of tin is detected from the intensity ratios.

Title: Packet exchange test system
Inventor: UENO CHISHIO
IPC: H04L12/70
Filed: 1991-05-10
Abstract: PURPOSE:To provide a packet exchange test system which can conduct an accurate test. CONSTITUTION:A clock generation part 7 generates a clock signal. A switch 8 changes over the clock signal from the clock generation part 7 to a state where it is supplied to a timer circuit and a state where supply is interrupted. Thus, a test control circuit gives the instruction of the start of the test to a line control circuit in a state where the supply of the clock signal from the clock generation circuit to the tier circuit is interrupted, and the supply of the clock signal from the clock generation circuit to the timer circuit is started after arbitrary time. Thus, all the timer circuits simultaneously start counting the clock signals.

Abstract: PURPOSE:To make the boundary face between a bushing and a resin-molded layer hard to exfoliate after a molding operation and to enhance the surroundings-resistant property of the title motor by providing the bushing in which a gap has been formed so as to be a cross-sectional shape in the fitted state of a protruding part to a recessed part in the bushing for a lead wire and which is composed of a fragile resin. CONSTITUTION:A split bushing 14 which is composed of a resin having a coefficient of thermal expansion close to that of a molding material and which holds lead wires is constituted of a half-split bushing 14e having a plurality of protruding parts 14a in which a plurality of ribs 14c have been formed radially and of a half-split bushing 14f having recessed parts 14b whose cross-sectional shape is e.g. circular so as to be fitted desirably to the outside diameter of each protruding part 14a. Consequently, in a molding operation, the protruding parts 14a and the recessed parts 14b at the half-split bushings 14e, 14f for the lead wires are deformed due to an internal pressure generated by a fitting operation. However, their deformation is absorbed by gaps 14f at fitting cross sections between the plurality of ribs 14 formed in advance at the protruding parts 14a and the recessed parts 14b, and an excessive internal stress is not generated.
