Title: Fastening lace comprising tubular lace body
Inventor: OSADA MASAKAZU
IPC: A43C9/00
Filed: 2017-02-08
Abstract: Laces having bulges according to prior art always have a core of elastic rubber, but they differ in the state of expansion and contraction of the portions of the rubber corresponding to the two end portions and the central portion of the bulge. In other words, even with the same elastic core, a portion that drastically expands and contracts coexists with a portion that does not expand and contract at all, and high strain accumulates at the boundary region between them, and when the strain reaches a limit, it ultimately ruptures. A problem with this art is that an operation by which strain accumulates in a relatively weak material like rubber is an essential operation. Proposed is a fastening lace comprising a tubular lace body made from an elastic material having bulges disposed repeatedly at intervals, the bulges changing in diameter according to a magnitude of axial-direction tension applied thereto, in which, of a central tube portion constituted of the tubular structure of the lace body, portions corresponding to a central portion of the bulges have a spherical shape.

Title: Alarm mechanism
Inventor: YOSHIZAWA KEIICHI
IPC: G04C21/20
Filed: 1993-01-28
Abstract: An alarm mechanism for an alarm clock has an alarm hand and an hour hand mounted coaxially with respect to each other and the alarm hand and the hour hand are formed with integral hubs having cam grooves and cam pawls. The cam grooves and cam pawls are positioned with the same positional relationship with respect to the hub portions of the alarm hand and the hour hand so that at a preselected alarm time, the cam grooves and cam pawls cooperatingly engage one another to thereby actuate a mechanism to sound the alarm of the alarm clock. The alarm hand has an alarm pinion gear formed integrally with the annular hub portion of the alarm hand. Thus, in attaching the hands to the clock during assembly, it is possible to attach the alarm hand and the hour hand at any random angular position without having to pay special attention to the respective positional relationships of the two hands.

Abstract: PURPOSE:To deal with unnecessary function instantaneously and positively by detecting differences between input voltage and current signals and output voltage and current signals and then making a judgment whether the differences are higher than predetermined values. CONSTITUTION:Voltages from input and output main circuits in a semiconductor circuit breaker 12 are provided, for respective phases, to a differential voltage detector 141 in a protection/detection circuit 14 and then they are compared to one another. When a voltage difference passed through an amplifier 142 exceeds a predetermined value, a protection detecting output 144 is produced as an unnecessary function of the semiconductor circuit breaker 12 upon provision of on ON operation command 127 of the semiconductor circuit breaker 12. Since voltage drop in the main circuitry of the circuit breaker 12 is low, input and output voltages thereof are approximately equal to each other. Consequently, unnecessary function of the semiconductor circuit breaker 12 can instantaneously and reliably be detected based on the differential signals and a load can be protected.

Abstract: 1,103,298. Calendar timepieces. EBAUCHES S.A. Jan. 24, 1967 [Feb. 22, 1966], No. 3598/67. Heading G3T. The control mechanism for the date indicator 1 of a calendar timepiece comprises two coaxial wheels 7, 11 rotatable at slightly different speeds and connected together by a spring 14 which becomes stressed as the angular displacement between the wheels increases, the wheel 7 being released once every twenty four hours whereupon its abrupt rotation indexes the date indicator one step forward. Pinions 8 and 13, fastened together on a hub 8a, drive the wheels 7 and 11 respectively, the wheel 7 having more teeth than the wheel 11. The spring 14 is located in a recess (15), Fig. 2 (not shown) in the lower surface of the wheel 11 and the ends 14a, 14b of the spring are bent at right angles to engage sector shaped openings 17 and 18 in the wheels 11 and 7 respectively. Initially the openings 17, 18 are aligned, but as the pinion 13 drives the wheel 11 at one revolution in twenty four hours, the wheel 7 is driven at a slightly slower speed by the pinion 8. The openings 17, 18 are relatively displaced and the spring stressed until a cut away segment 19 of the wheel 7 releases the wheel from its pinion 8. The sudden rotation of the wheel 7 then causes its pin 6 to engage teeth 5 of the date indicator which is advanced by one step. A detent 4 locates the indicator 1 in each position. To conserve power in an electric timepiece, the detent 4 may be raised at the moment of advancing the indicator, the pin 6 remaining in the path of the teeth 5 at the end of the operation to prevent the indicator advancing two teeth at a time.
