A method for manufacturing a honeycomb structure includes producing a pillar-shaped honeycomb molded body in which a plurality of cells are placed in parallel with one another in a longitudinal direction with a cell wall therebetween by molding a ceramic raw material; and producing a honeycomb fired body by carrying out a single or a plurality of treatments including at least a firing treatment on the honeycomb molded body. The method further includes temporarily storing the treated honeycomb molded body on which the single or plurality of treatments have been carried out in a molded body storage container; taking out the treated honeycomb molded body placed in the molded body storage container from the molded body storage container; and conveying the taken-out honeycomb molded body to a subsequent process.

A phase-locked loop circuit having a loop filter supplied with a detection indication of a phase difference between an input signal and an output signal from a voltage-controlled oscillator to control the oscillation of the voltage-controlled oscillator. The loop filter includes a first capacitance element connected between an output terminal of the loop filter and a first power supply potential point, a second capacitance element connected between the output terminal and a second power supply potential point, a third capacitance element connected in parallel to the first capacitance element when a first indication is obtained by the detection of a phase difference, a fourth capacitance element connected in parallel to the second capacitance element when a second indication is obtained by the detection of a phase difference, and control members for forming a first current path between the output terminal and the first power supply potential point when the first indication is obtained and for forming a second current path between the output terminal and the second power supply potential point when the second indication is obtained. The phase-locked loop circuit can be readily fabricated in the form of an integrated circuit, and it is possible to conduct a lock-in operation speedily and reliably at the time when the circuit power supply is turned on.

A degreasing jig assembling apparatus includes a robot arm and a table or a conveyor on which a degreasing jig including a bottom plate and a cover member is placed. A ceramic molded body is mounted on the degreasing jig upon degreasing the ceramic molded body. The ceramic molded body is mounted on the degreasing jig on the table or the conveyor. The degreasing jig assembling apparatus further includes a molding body mounting mechanism and a cover member. The molding body mounting mechanism mounts the ceramic molded body at a predetermined position on the bottom plate placed on the table or the conveyor by using the robot arm. The cover member attaching mechanism attaches the cover member to the bottom plate in a manner so as to cover the ceramic molded body mounted on the bottom plate.
