Title: Speed increased chain conveyor
Inventor: NAGURA NARIYUKI
IPC: B65G17/24
Filed: 1984-07-31
Abstract: PURPOSE:To enable a large speed increasing ratio to be provided and a carried material to be conveyed stably by installing a conveying roller of a large diameter coaxially onto a chin axis so as to rotate together with a chain roller due to frictional contact while the chain roller rotates on the rail. CONSTITUTION:Rotation of chain rollers 16A and 16B on the rail 14A and 14B causes a chain 10 to travel. Simultaneously, conveying rollers of a large diameter 18A and 18B are caused to travel, because they are arranged coaxially onto a chain axis 12A and 12B so that the frictional contact makes them rotate. A carried material 20 placed on the conveying rollers 18A and 18B travels faster because the conveying rollers 16 are speeded up since they have a large diameter than the chain rollers 16 while being rotated together with the chain rollers. This configuration enable the diameter of the conveying roller to be increased to the equivalent pitch of the chain axis permitting the stable conveying operation to be obtained with the large speed increasing ratio provided.

Title: Output attenuation compensation circuit of low-pass filter
Inventor: HOSHINO TOSHINORI
IPC: H02P9/00
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To compensate the output attenuation of the low-pass filter(LPF) of a generator voltage effective value calculation circuit in a frequency range which is lower than its cut-off frequency. SOLUTION: When a generator voltage detected by an instrument transformer is let through an LPF with a cut-off frequency of 120 Hz and subjected to an A/D conversion to calculate the effective value of the voltage, the output of the LPF is attenuated even in a frequency range between 70 Hz and 120 Hz, which is the cut-off frequency of the LPF owing to the characteristics of the LPF. Therefore, when a generator frequency is elevated, the calculated result of the effective value shows a low value.  As the 70 Hz-120 Hz attenuation characteristic of the LPF is linear, when the frequency of the generator voltage is elevated, an approximately linearly attenuated attenuation factor in a frequency range of 70 Hz-120 Hz, which is a frequency range of approximately 1.4-2.4 times that of a reference frequency, is calculated by a linear approximation formula, and the calculated result is added to the calculated voltage effective value to compensate for the attenuation of the voltage effective value owing to the characteristics of the LPF.
