Title: Foreknowledge repeat control system
Inventor: TOYOSAWA YUKIO
IPC: G05B21/02
Filed: 1991-04-24
Abstract: PURPOSE:To converge the position deviation to zero even in the case of a command which is repeated with a prescribed period and includes an asynchronous component which is not synchronized with this period. CONSTITUTION:A repeat controller 5 and a reverse system feed forward controller 6 of a controlled system 4 are provided in parallel in the servo control system of a servo motor. The feed forward controller 6 consists of an FIR digital filter, and a future command P is inputted by an order N of the controlled system. The coefficient of the filter is automatically determined by the inputted command P and a position deviation epsilon so that the feed forward controller itself has the reverse system. Since the transfer function of the feed forward controller is a reciprocal of that of the controlled system, the transfer function of an output omega to the command P is '1', and the position deviation is logically eliminated and the position deviation is very reduced.

Title: Charge management device in transfer rotor system
Inventor: FUKUYASU AKIO
IPC: B60L3/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To comprehend the charged state of the charging-type battery of a transfer robot more accurately and prevent the battery from expiring during an operation. SOLUTION: A transfer robot detects the charged state of a charging-type battery by a charge state detecting means and transmits the charged state information data to a control station. As a result, in a control station, the residual capacities of the rechargeable-type batteries of the respective transfer robots can be known more accurately, in accordance with the charge state information data. The control station determines whether one battery requires charging or may be put into an ordinary operation, in accordance with the known residual capacity of the battery. With this constitution, problems of the battery being expired during the operation and the transfer robot being usable to travel to a charging stations by itself are prevented.

Title: Fin-plate heat exchanger
Inventor: TANIGUCHI MITSUNORI
IPC: F28F17/00
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To obtain a tin-plate heat exchanger in which abrupt decrease of heat exchanging quantity can be suppressed upon frosting while decreasing the number of times of defrost operation and shortening the defrost operation time. SOLUTION: Choking of an air flow channel can be delayed unit the tins 1 on the downstream side, where the frosting quantity is low, is choked by performing mechanical defrosting on the upstream side of the fin 1 using a defrosting means, i.e. a frost scraper 3, made of a series of metals inserted between the fins 1 on the upstream side movably along the fin 1. Furthermore, since the frosting quantity is high at the front edge on the upstream side at the fin 1 and the frosting quantity can be decreased on the downstream side, abrupt decrease of heat exchanging quantity due to decrease in the quantity of air flow can be suppressed and the number of times of defrost operation can be decreased. Since defrosting is performed using the frost scraper 3 at the front edge on the upstream side of the fin, the defrost operation time can be shortened.

The detection signal 81 of the photosensor 52 is supplied to and averaged by an integration circuit 82 and a comparator 83 compares the averaged signal outputted by the integration circuit 82 with a reference signal 85. A CPU 71 when supplying a digital signal 89 from a latch 90 judges whether the reverse surface of the original 3 is up or not and when so, the original 3 is turned over by passing through the 1st carry-in path 5 and sent to platen glass; when the top surface is down, the original is sent to the platen glass 8 without being turned over. Therefore, the original is sent to the platen glass 8 as specified regardless whether the image information side of the original 3 is up or down. Consequently, the operativity and operation efficiency are improved.
