Abstract: 166,287. Hanman, J. L. Oct. 12, 1920. Hubs; detaching from, and attaching to, permanent hubs.-Relates to means for securing wheels, pulleys, and other articles on axles and shafts of the kind comprising a cap engaging the end of the axle or shaft with an interrupted screw-thread' and locked by a sleeve slidably but non-rotatably mounted on the cap and spring- pressed into engagement with the face of the wheel, pulley, or the like. The invention, which is described as applied to the attachment of a detachable wheel i, Fig. 1, to an axle sleeve n, consists in providing on the cap c, Fig. 2, and locking-sleeve a, shoulders c* and a* respectively which provide abutments and a housing for the compression spring d by which the sleeve is actuated so as to interengage the diametrically disposed projections and recesses f, g. The cap has a male member j provided with interrupted threads k adapted to engage similar threads l on the sleeve n by an axial and rotary movement. To ensure correct positioning of the cap on the sleeve n, a pin-and-slot guide may be provided. In a modification, Fig. 7, the cap c has an internal interrupted thread, the sleeve a is guided non-rotatably on the cap by a pin e and slot c<2> and the recesses g are formed on the sleeve and the projections on the wheel. Accidental disengagement of the locking sleeve may be prevented by a nut screwed on the cap and bearing on the sleeve or vice versa.

Title: Method for inspecting analog switch integrated circuit
Inventor: MORI MASAMICHI
IPC: G01R31/316
Filed: 1989-01-04
Abstract: PURPOSE:To perform inspection without any external parts by using the pin switching function of a tester and setting input signal terminals for analog signals and signals of control circuits according to the purpose of measurement. CONSTITUTION:For example, when a source current is measured, the pin switching function of the tester which has a switch matrix is used. The input signal terminals of analog switches S1 - S9 and the control signals of the control circuits C1 - C6 are set to a current measurement state. Then individual characteristics are measured by a power source VCC terminal to measure the source current without any external parts. Thus, no external parts for the input/output terminals of the switches S1 - S9 is required, so a special measuring jig is not necessary. Even if terminal positions are different, the current can be measured by utilizing the pin switching function. Further, the characteristics of the switches S1 - S9 are measured directly, so characteristic variation which causes a function defect is detected in advance.

Abstract: PROBLEM TO BE SOLVED: To reduce remarkably 'eye mucus' stuck to an extruded face of a mouthpiece by a method wherein at least a face of an extruded tip part of the mouthpiece is coated by a diamond-like carbon thin layer. SOLUTION: At least an extruded tip part of a mouthpiece, i.e., a face of the tip part from which a molten polymer is extruded is necessarily coated by a diamond-like carbon(DLC) thin layer. The diamond-like carbon(DLC) thin layer is an amorphous hard carbon layer which is generally 0.5-4μm in layer thickness and composed of hydrogen and carbon. Though a diamond structure is sometimes partially contained according to a manufacturing method, most thereof is composed of an amorphous structure. Material being a eye mucus is difficult to stick to the DLC on the surface of the mouthpiece tip part from which the molten polymer is extruded since releasability of the molten polymer is excellent.
