In a method of detecting deterioration of a battery pack consisting of a series assembly of a plurality of battery modules during charging, on the basis of a voltage difference between a plurality of battery modules, deterioration detection is inhibited until a predetermined capacity is charged after starting of the charge. Also, in a detection apparatus for deterioration in a battery pack according to the present invention, a deterioration reference discharge voltage value which should correspond to a discharge current value and a temperature value is calculated on the basis of reference data, and the deterioration reference discharge voltage value is compared with an actual discharge voltage value to judge whether deterioration occurs or not.

An image forming apparatus has a toner recycling mechanism for effecting toner recycling. The image forming apparatus includes a developing unit accommodating developer for developing an electrostatic latent image formed on the surface of a photosensitive member, a cleaning unit for recovering developer remaining on the surface of the photosensitive member after development, and a toner recycling assembly. The toner recycling assembly includes a developer conveyor pipe through which the developer recovered by the cleaning unit is conveyed to the developing unit for recycling of toner contained in the developer, and also includes a developer supply or transport pipe for supplying the developer accommodated in the developing unit to either the developer conveyor pipe or the cleaning unit.

A thread checking device is installed in combination with a sewing machine in order to exert a proper tension on the thread loop formed at the eye of the needle when the thread loop passes through betweeen the bobbin case and the rotation stopping member for restraining rotation of the bobbin case. This thread checking device is provided with thread suspending means which comprises a thread suspending part disposed near a specified position where the thread guide of the thread take-up member is located when the needle thread loop passes between the bobbin case and the rotation stopping member. The thread suspending means suspends the needle thread held on the thread guide with the suspending part when the take-up member moves from the maximum thread take-up position to the maximum thread slack position.

A method and apparatus for processing an insulated wire. A long continuous wire coated with insulation covering is paid out intermittently, fed by a predetermined amount, clamped and cut into short wires with their opposite ends are stripped automatically. The method is performed by a device comprising a wire measuring section including a pair of measuring rollers to hold the wire and pay it out intermittently by a predetermined amount, a wire feeding section having a pinch rollers to feed the paid-out wire similarly by a predetermined amount, a wire cutting section having a wire cutter and a pair of insulator cutters, and a wire holding and transferring section to transfer cut-off short wires for final treatment.
