Abstract: A packaging strip has a series of receiving cavities formed thereon for each receiving an electronic component therein. Each of the receiving cavities is internally provided along peripheral edges with ribs and near a central area with a stepped land portion. The electronic component is received in the receiving cavity with its peripheral edges rested on the ribs, so that most part of the electronic component is suspended in the receiving cavity and a distance is kept between contacts at a bottom surface of the electronic component and a bottom of the receiving cavity. The stepped land portion restricts the electronic component from moving in the receiving cavity. When the packaging strip is wound into a roll and compresses the receiving cavities, the land portions arch to elevate the electronic components, protecting contacts of the electronic components from damage due to collision with the receiving cavity.

Abstract: Improved frequency stabilizing equipment for a light source for optical communication is provided. Light from the light source is selected by a light switch. An external modulator is used to perform amplitude modulation of modulated light selected by the switch. The modulated light passed through a dispersion generator having a wavelength-dependency characteristic is mixed with a local oscillating light signal outputted from a photoelectric converter. The mixed light is converted photoelectrically by a light receiver having a non-linearity characteristic between an input light signal and output electrical signal. By using photoelectriclly converted electrical signal, a difference in phase between the light signal inputted into the dispersion generator and the output light signal of the dispersion generator and the wavelength of the modulated light outputted from the light source is controlled so that the phase difference is a predetermined reference value.

Abstract: A film-tape eraser with normally retracted dispensing head includes an upper case, a lower case, and a dispensing mechanism pivotally connected to and located in the lower case. The upper case is also pivotally connected to the lower case to shield an upper part of the latter, while the dispensing mechanism is partially exposed from a top of the upper case. A downward push at a top of the dispensing mechanism would sink the dispensing mechanism and bring the dispensing head to a position exposed from a lower front of the lower case. When the dispensing mechanism is released from the downward push, an elastic strip at the bottom of the dispensing mechanism springs the dispensing mechanism up and brings the dispensing head to a retracted position in the lower case.

Abstract: A device for detecting arc fault which distinguishes harmful arc from the signal generated by operation of a dimmer and start of electronic devices. Signals outputted from a current transformer is attenuated by a resistor which is coupled in parallel to the current transformer. By the attenuation of the resistor, the signal generated by the operation of a dimmer is not determined to be arc in arc determining part. Harmful arc and the signal generated by the start of the electronic device are distinguished by integrating both signals. As the harmful arc lasts for a long time, large signals are integrated in an integrator while the signal generated by the start of electronic device does not last for a long time.
