Abstract: The invention prevents data from leaking. In a data management system (1), a terminal device (2) saves a remaining data among the remaining data and an incomplete data acquired by partitioning an image data of an ID card of a user in a storage unit, and uploads the incomplete data to a data management server (5) via a network (N). A data recovery device (4) acquires the remaining data from the terminal device (2), and acquires the incomplete data from the data management server (5) via the network (N). Further, the data recovery device (4) recovers the image data of the ID card of the user from the remaining data and the incomplete data.

Abstract: It is enabled to facilitate fine adjustment of power as well as reduction of the amount of movement required to maximize the power. An actuator 13 is moved by operation of a user. A pressure sensitive sensor 15 detects applied pressing force. A pressing member 14 presses the pressure sensitive sensor 15. When the amount of movement of the actuator 13 is smaller than a predetermined amount, the pressing member 14 presses the pressure sensitive sensor 15 to apply force corresponding to the amount of movement of the actuator 13. When the amount of movement of the actuator 13 is not smaller than the predetermined amount, the pressing member 14 presses the pressure sensitive sensor 15 to apply force corresponding to pressing force applied to the actuator 13 by the user.

Abstract: A housing includes a case member having an opened front face, and a cover member firmly fixed with the case member to close the opened front face of the case member. The case member has a penetration hole penetrating its side face. A movable part includes an inner member disposed inside the housing to control a circuit, and an outer member being a discrete piece from the inner member and exposed outside the housing to be manipulated by a user. The outer member includes a shaft part inserted through the penetration hole.

Abstract: Disclosed is a direct current switch which comprises, in a housing, a slidable actuator, one stationary contact and one pseudo stationary contact both fixed to the housing, a seesaw-like plate having one movable contact and one pseudo movable contact fixed to its opposite ends, and a swingable pusher operatively connected to the actuator to apply a pushing force to the seesaw-like plate all the time. The seesaw-like plate is supported by a fulcrum support to be balanced in the middle. The seesaw-like plate has an engagement piece fixed thereto in the vicinity of the movable contact, and the actuator has a resilient catch-and-hold piece fixed thereto on the movable contact's side.

Abstract: Disclosed is an improved switch structure having forcedly opening-and-locking mechanism installed therein. It is responsive to the sticking of the movable and stationary contact elements for forcedly breaking an associated heavy-current carrying circuit which otherwise, would remain closed through the stuck contact elements. The forcedly opening-and-locking mechanism comprises an auxiliary contact section spring-biased to retain the stationary contact element in conductive condition to the associated circuit. It is responsive to the sticking-and-rising of the movable and stationary contact elements for allowing the stationary contact element to be apart from the conductive position to the associated circuit by yielding the rising force of the stuck contact elements until the locking position is reached, in which position the stationary contact element is kept in non-conductive position.

Abstract: An improved phase controller is operatively connected to the operating lever or trigger of an electrically powered tool for supplying its motor with electric power from an ac power supply. It includes a device for establishing a divisional voltage derived from the ac voltage across the electric power supply. A variable resistor-and-capacitor series-connection is connected across the motor-and-power supply series-connection. A device provided for supplying the ac motor with electric power when the charging voltage across the capacitor rises above the divisional voltage. The variable resistor is operatively connected to the operating lever, and the capacitor can be charged with electricity at a charging rate which is determined by the variable resistance and the fixed capacitance under the control of the operating lever.

Abstract: An operation-staggered dual switch is provided having a casing, first and second switching mechanisms installed in the casing, the switching mechanisms being operatively connected such that operation of the first switching mechanism may follow operation of the second switching mechanism after a predetermined delay, wherein the operation-staggered dual switch includes delay means comprising a connection rod having indentations formed on one side, a train of toothed wheels having a leading toothed wheel and a trailing toothed wheel, the leading toothed wheel of the train of toothed wheels being engaged with selected indentations of the connection rod, and a rotary damper connected to the trailing toothed wheel of the train of toothed wheels, the connection rod being responsive to initiation of operation of the first switching mechanism for moving in a given direction.

Abstract: A high-speed breaking switch of the seesaw type having an up-and-down contact plate balanced at the middle by the support of the switch body, a push member slidably attached to the up-and-down contact plate to push the up-and-down plate against the support all the time and at least one terminal formed on the switch body to permit one end of the up-and-down contact plate to abut thereon. The up-and-down contact plate has a raised fulcrum vertically at a level which is higher than the level at which the push member abuts on the up-and-down contact plate. The raised fulcrum is formed by a pair of raised fulcrum archs, one on each side of the contact plate. The up-and-down contact plate has a ramp-and-step plateau or inverted "V"-shaped projection formed thereon.
