摘要： A double side grinding apparatus and a double side polishing apparatus, with a narrow tolerance range, reduces pitching errors, and ensures a sufficient level of rigidity against the force of reaction to machining, while enhancing positioning accuracy. The double side grinding apparatus or a double side polishing apparatus includes a plurality of guideways for supporting and shifting main spindles, and these plural guideways on end define a geometric center matched with the center of gravity of the main spindles. The number of the guideways is preferably three in order not to obstruct the mounting and removal of a workpiece.

摘要： A high frequency television signal receiving apparatus providing excellent linear detection of output characteristics by improving the phase characteristic of the picture synchronous detector. A variable capacitive element is equivalently connected in parallel to a reference solid-state oscillation element. The reference solid-state oscillation element controls the frequency of a local oscillation device including a PLL circuit for feeding a local oscillation signal to a mixer for converting a high frequency signal into an intermediate frequency signal. A first low pass filter is connected between a phase comparator for detecting a phase difference of the intermediate frequency signal and the output of a detection oscillator for generating a detection oscillation signal with a specific phase difference. A second low pass filter having a larger time constant than the first low pass filter is connected to the variable capacitive element. The capacitance of the variable capacitive element is varied by the output voltage of the phase comparator. The signal frequency of the local oscillation device is shifted, and is controlled to converge the frequency of the intermediate frequency signal within the frequency range of the detection oscillation signal.
