An optical transceiver is disclosed, where the optical transceiver includes an optical subassembly (OSA) with a bottom plate for dissipating heat and connected to an electronic circuit with a flexible printed circuit (FPC). The FPC is soldered with the side electrodes of the OSA as forming a solder fillet in the plane electrode, or the FPC is soldered with the plane electrodes of the OSA as forming the solder fillet in the side electrodes, and leaving a limited room for receiving the curved FPC in peripheries of the OSA.

A voltage non-linear resistor unit is composed of at least one of voltage non-linear resistors which is composed of a columnar sintered body formed by molding and sintering a raw material, the sintered body having both end surfaces having a surface roughness in term of arithmetic average surface roughness Ra of 1 to 2 &mgr;m and being formed with an electrode film layer, a terminal metal fitting formed in a predetermined shape and attached to the voltage non-linear resistor, and a soldering material arranged between the voltage non-linear resistors and between joint surfaces of the voltage non-linear resistor and the terminal metal fitting, the joint surfaces being joined by heating the soldering material and applying a load vertically to the joint surfaces while giving a rotation motion thereto. Such voltage non-linear resistor is effectively assembled into an arrester.

A discharge counter relating to an operation of a lightening arrester to protect a power system and electric apparatus from overvoltage. This discharge counter includes a lightening arrester terminal, a grounding terminal, a nonlinear resistor connected between the lightening arrester terminal and the grounding terminal, a capacitor connected to the nonlinear resistance in parallel between the lightening arrester terminal and the grounding terminal, and a counter for counting the number of times a discharge current flows from the capacitor. Further, the counter is connected in parallel to the nonlinear resistance and capacitor. The nonlinear resistor includes a nonlinear material. That is, the nonlinear material is equal to a nonlinear resistance which includes zinc oxide as a main component and bismuth oxide and titanium oxide as a sub component, which have an excellent characteristic for the discharge counter.

If cylinder bores formed in a caliper parallel to each other are communicated together through a pipe casted in the caliper, the pipe tends to come out of the caliper into a cylinder bore. A separate short pipe is provided to communicate the cylinder bores. The pipe has an engaging portion so as to extend in a diametric direction of the short pipe to prevent longitudinal shift of the short pipe. The engaging portions can be provided easily by forming a recess or a protrusion on the outer periphery of the pipe and casting the pipe in the caliper.
