A circuit breaker includes a movable contact, a fixed contact, a switching device, a switching operation handle, and an over-current tripping device. The switching device has a switching lever connected to the handle, a toggle linkage having an upper link and a lower link for connecting to the movable contact, a tripping mechanism for activating the toggle linkage in response to over-current, and an operation spring tightly stretched between the switching lever and the toggle linkage. A locking member is provided in the switching device for interconnecting the toggle linkage and the switching lever and for restricting a movement range of the switching lever according to an operational position of the toggle linkage. When main-circuit contact points are stuck, the locking member restricts the movement of the switching lever and prevents the handle from moving to the OFF position.

In a resistive-film type touch panel having two resistive-film sheet, a first resistive-film sheet has a power supply means connected to it which generates in it a voltage gradient and the second resistive-film sheet detects a voltage which corresponds to a pressed position on the touch panel. Voltage information corresponding to pressed position coordinate values detected from the two resistive-film sheet is transferred to an A-D conversion means via a switching means for determination of the pressed position on the panel. A non-display region of the panel is provided with function keys, and the panel is additionally provided with a notification means and a non-display region pressing detection means, the notification means making notification of the output from the non-display region pressing detection means, which indicates that the non-display region has been pressed, without intervention of the analog-digital conversion means, directly to a processing/control circuit.

A circuit breaker includes a fixed contact; a movable contact disposed in a rotary-type contact holder; a switching device; an operation handle; and an over-current tripping device. The operation handle is operated to open and close main-circuit contact points through the switching device. The switching device includes a handle lever connected to the operation handle; a toggle linkage having an upper toggle link and a lower toggle link; a switching spring placed between the handle lever and an arm connecting point of the toggle linkage; and a side plate for holding the components. The circuit breaker further includes a device for preventing the operation handle from moving to an off position when the contact points are stuck together. The device includes first stoppers formed on a cross bar of the contact holder and the handle lever facing the cross bar, and a second stopper formed on the side plate.

A driver stores an electricity consumption value of corresponding input/output hardware. The stored electricity consumption value is registered in an electricity consumption value table in accordance with a setting of the driver when an operating system carries out input/output function. When an application program requires to use the input/output function, the operating system judges whether or not the required input/output of data can be stably carried out with the remaining quantity of the battery measured by a battery remaining quantity measuring instrument, and it is judged that the input/output can be carried out stable, the operating system allows a corresponding driver to drive the input/output hardware. With this feature, the operation of an input/output device is prevented from being unstabilized due to shortage of battery volume without changing an operating system even when electricity consumption of the input/output device is varied due to a setting or the input/output device is exchanged or newly added.

In a portable information instrument including a housing having an window, and a display screen accommodated within the housing but exposed in the window to display data processed in the portable information instrument, a cover sheet for protecting the display screen is formed of a soft back sheet and a plurality of rectangular hard pieces fixed on the back sheet. An accommodating mechanism is provided within an inside of the housing, and is spring-biased to retract the cover sheet into the inside of the housing. A stopper mechanism is also provided within the inside of the housing, for inhibiting accommodation of the cover sheet into the inside of the housing by the accommodating mechanism. A sensor is provided within the inside of the housing, for detecting passage of the rectangular hard pieces before the sensor, and an information processor located within the inside of the housing, counts a detection signal generated by the sensor, for activating the stopper mechanism when a count value reaches a predetermined value.

In an injection apparatus, a guide screw shaft of a body section (20) and a screw of an operation knob (34) of a movable section (30) allow the movable section (30) to move relative to the body section (20). An ampule (7) is radially inserted into a ampule holding portion (36) of the movable section (30) and temporarily held by means of an elastic blade (36a) and at the same time, a flange (75) of the ampule (70) is inserted into a flange insertion portion (38). When the operation knob (34) is rotated, the movable section (30) moves toward the body section (20) together with the ampule (70). A guide sleeve formed in the body section (20) is inserted into a syringe (77) of the ampule (70). An operation knob (50) is rotated to set the feeding amount of a piston rod, and the operation knob (50) is pressed to perform an injection. When a release button (40) is pressed, the piston rod is returned to an initial position. This construction allows the ampule (70) to be easily mounted on the injection apparatus and the state of medicine in the ampule (70) to be easily seen.
