Title: Parts supplying to electronic parts mounting machine under operation
Inventor: YAMAMOTO HIROKI
IPC: H05K13/02
Filed: 1993-02-19
Abstract: PURPOSE:To provide a parts supplying method capable of improving operating efficiency, by enabling supply of parts whose reside is little, without interrupting the mounting operation of an electronic parts mounting machine. CONSTITUTION:When parts whose residue is little are generated during operation in a program 1 (S101), the parts name and the set position in a parts supply part are informed (S102). A program 2 is formed (S103) in which many parts of the same kind to be mounted on a board are selected and continuously mounted by priority. At the time point that a board during mounting ends mounting (S104), and mounting of the next board starts, the program 1 is automatically changed over to a program 2 (S105). Then the parts whose residue have become little are supplied (S107). Hence when parts have become out of stock during operation of an electronic parts mounting machine, the parts can be supplied while the mounting machine continues production operation. Thereby productivity can be improved.

Title: Burner system
Inventor: ICHIRAKU YUUICHI
IPC: F23C99/00
Filed: 1995-01-26
Abstract: PURPOSE: To improve the thermal efficiency and to reduce the NOx in a cogeneration system using exhaust gas containing low oxygen concentration. CONSTITUTION: In a cogeneration system of the type in which boiler water is reheated by exhaust gas containing oxygen content of 13% or less by a fully fired burner 1 and supplied to an exhaust heat boiler 2, first the air having an air ratio of less than '1' and fuel are supplied to the burner 1 to form a primary flame A, the exhaust gas is brought into contact with the flame A to be secondarily burned. Thus, since it is not necessary to introduce the atmosphere of low temperature to the high temperature exhaust gas, its heat utilizing efficiency is improved, and further the blower of a large capacity is not required.  Since the oxygen is supplied at the two stages so that the combustions become slow, NOx value can be reduced, and further even if the exhaust gas supply quantity to the burner is relatively excessive, the combustion does not become unstable, and hence the turn down ratio can be increased.
