Title: Combustion equipment
Inventor: TOMIZAWA TAKESHI
IPC: F23C13/00
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To reduce electric power for preheating a catalyst on the occasion of starting combustion by a method wherein catalyst combustion is started by a second catalyst body by heating it to the heat of reaction thereof or above by electrifying an electric heater at the time of the start of the combustion and by starting then the combustion by a first catalyst body by heating it to the heat of reaction thereof or above by the heat of combustion of the second catalyst body. SOLUTION: An electric heater 19 being electrified before the start of combustion, it is detected from a change in the temperature of a second temperature detecting part 24 that the temperature on the upstream side of a second catalyst body 13 reaches 500 deg.C, and supply of fuel is started. Liquid fuel is sent from a fuel supply part 1 to a vaporizing part 4, vaporized herein, mixed with air from a blower 5 and jetted out from a jet port 7. The fuel-air mixture passing through a first catalyst body 12 not being heated yet reacts in the second catalyst body 13 heated, and when the reaction proceeds and the temperature at the upstream end of the second catalyst body 13 reaches 800 deg.C, the temperature at the downstream end of the first catalyst body 12 is raised by the heat of radiation from the high- temperature face of the upstream end of the second catalys body.  After the temperature at the upstream end of the first catalyst body 12 reaches 500 deg.C, the combustion is started at the first catalyst body 12.

Title: Liquid crystal device and driving method therefor, and projection display device
Inventor: YAMADA SHUHEI
IPC: G02F1/1368
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal device and a driving method therefor, which prevents discrimination from occurring and is enabled to display in high picture quality. SOLUTION: A scanning line driving circuit 15 scans scanning lines 2 (2-1-2-N) with a period shorter than a frame period and synchronizing with the frame cycle. The data line driving circuit 14 drives data lines so that pulse signals corresponding to gradations to be displayed with positive and negative constant voltages can alternately be applied to pixels at each frame. Since liquid crystal is driven with the positive and negative constant voltages in such a configuration, if the constant voltages are set to saturation level or more, small variations in the voltages applied to the liquid crystal have little influence on the transmittance of the liquid crystal and do not cause flickering, therefore, frame inversion driving is possible.  As the result, since it is possible to reduce discrimination occurring on the boundary part of pixels, a bright, sharp-contrast, and easy- to-see display can be obtained.

Filed: 1989-09-11
Abstract: PURPOSE:To detect a faulty section accurately by opening a switch nearest to the power supply side in the faulty section decided and finally deciding the faulty section on the basis of the fault detecting information of the slave station after opening. CONSTITUTION:A switch SS12 nearest to the power supply side is selected from switches SS12, SS13 surrounding a faulty section S3 decided. An opening command is transmitted over the switch SS12 through a communication line 60, a slave station 2, etc., and the switch SS12 is opened. The switch SS12 is opened, and the continuation of fault is decided on the basis of the fault detecting information of the slave station 2 collected through the communication line 60. The faulty section is judged finally on the basis of the result of the decision. Accordingly, a section, a second section S2, on the power supply side adjacent to a temporarily decided faulty section is judged finally as a fault section when fault continues as the result of the decision of the continuation of fault, and the temporarily decided faulty section, i.e., the third section S3, is judged finally as the faulty section when fault disappears.

Title: Action defining method for input/output means
Inventor: ARAI TOSHIFUMI
IPC: G06F3/02
Filed: 1987-09-24
Abstract: PURPOSE:To simplify the designation for contact among plural input/output means requiring the complicated descriptions by using a function which defines an action in case the value of a memory means used for definition is changed. CONSTITUTION:A counter device 101 outputs its present count value via an integer value output means 103.
