  • Patent number: 10376606
    Abstract: A sterilizing sheet is excellent in terms of saving space when a sterilizing operation is being performed, and sterilizing objects of various sizes. This sterilizing sheet is provided with a flexible sheet body, a sheet accommodating body and a handle. The sheet body is formed from a dielectric and a pair of electrodes accommodated inside the dielectric. The sheet accommodating body is a cylindrical body in which the sheet body is accommodated to be capable of being pulled out and rewound, and is provided with a case, a rotating body and a rewinding mechanism. The rewinding mechanism is a mechanism for automatically rewinding the sheet body, when pulled out from the sheet accommodating body, back into the sheet accommodating body. The handle is attached to a distal end portion of the sheet body, and includes, inside the handle, a battery, a switch mechanism, a booster circuit and a monitoring circuit.

  • Patent number: 9960713
    Abstract: An impact producing actuator can vary energy to be applied to a shape memory alloy, depending on, for example, an ambient temperature. The impact producing actuator has a drive signal generation unit that generates a drive signal based on a single pulse signal generated in response to an input operation and outputs the drive signal, a switching element whose switching operation is controlled by the drive signal, and a shape memory alloy through which electric current passes for a period of time during which the switching element is turned on or off. The impact producing actuator is configured such that the period of time during which the switching element is turned on or off varies depending on the ambient temperature.

  • Patent number: 9503083
    Abstract: A force feedback-type touch panel device is provided which can provide an operator with clearer feedback than that of conventional art by presenting the operator with vibration having a larger vibration amplitude than that of conventional art and can prevent any breakage or damage of a touch panel when an external impact is applied to the touch panel. The touch panel device includes a base member, a touch panel retained by the base member, a cover member formed in a shape covering the touch panel with a hard synthetic resin, and an actuator that causes the cover member to be displaced along the perpendicular direction with respect to a flat surface of the touch panel. The cover member is urged in the direction toward the base member using an attraction force generated between a first magnet fixed on the base member and a second magnet fixed on the cover member.
