Title: Grounding protective cover
Inventor: KIMOTO AKIO
IPC: H02G7/00
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To obtain a grounding protective cover whose placement property to an exclusive mounting tool is enhanced and by which an operation can be performed quickly, surely and safely, by a method wherein an uneven part for slip prevention which comes into contact with the cam of a fixation part at the exclusive mounting tool is formed in an end edge part, and/or a protrusion part is formed in an end part. SOLUTION: A plurality of fine uneven parts 9 are formed in the end edge part of a grounding protective cover 1 which is gripped by the cam 5 of a fixation part in an exclusive mounting tool and by a gripping part 6 whose cross section is U-shaped. Since the uneven parts 9 exist, the grounding protective cover 1 can be gripped firmly without being slipped when it is pressed by a cam face 5a. Alternatively, instead of the uneven parts 9, a protrusion part 10 is formed in the end part of the grounding protective cover 1. When the grounding protective cover 1 is pressed and gripped by the cam 5, a tensile force acts due to the elasticity of the grounding protective cover 1 because the protrusion part 10 exists.  Even when the grounding protective cover 1 is going to come off from the fixation part, the protrusion part 10 is hooked by the cam face 5a of the cam 5 so as not to come off the gripping part.

Filed: 1993-11-11
Abstract: PURPOSE:To attain miniaturization, low cost and low power consumption by simplifying the configuration of the frequency multiplier circuit outputting even order harmonics with respect to an input frequency. CONSTITUTION:A 1st transistor(TR) Q1 and a 2nd TR Q2 form a differential pair. Thus, currents each flowing to a collector of each of the TRs Q1, Q2 based on a signal, whose frequency is (f), applied to input terminals 1a, 1b are the same in the quantity and opposite in the phases and cancelled in an impedance circuit Z and the signal whose frequency is (f) is not given to an output terminal 2. On the other hand, since the phase of even order harmonics generated respectively in the 1st TRQ1 and the 2nd TRQ2 is same in phase, the currents are not cancelled in the impedance circuit Z and given to the output terminal 2. The impedance circuit Z is formed to have an impedance at a frequency band at the second harmonic 2f especially.
