The present invention is a block oriented control system that allows interoperability between devices made by different manufacturers. A block oriented control system is a system which includes a plurality of field devices incorporating a physical layer, communication stack, and user layer, with the field devices being connected by a transmission medium, such as a bus. The physical layer receives signals from the bus and translates the signals into a message for the communications stack, and receives messages from the communications stack and translates the messages into signals for the bus. The communication stack controls the communications between devices operating in the control system. The user layer is a block oriented approach to the system's control functions, and includes function blocks and system management. The function blocks are standardized encapsulations of control functions, such as analog input or proportional/derivative. The system management allows synchronization of the device applications and the network processing.

This invention relates to a method for manufacturing a flat display panel device suitable for being applied to a plasma display panel and the like. In the method comprising forming a barrier-ridge-forming layer over a whole surface of a substrate having an electrode pattern, then removing from barrier-ridge-forming layer the unnecessary portions by jetting an abrasive, so as to form a barrier ridge, and further filling the removed portions with fluorescent paste layer and removing from fluorescent paste layer the unnecessary portions by jetting the abrasive until a given discharge space can be kept. Organic material particles coated with an inorganic material are used as the abrasive for removing the barrier-ridge-forming layer and/or the fluorescent paste layer. By coating the organic material with the inorganic material, the abrasive particles become roundish. Thus, even if these are used as the abrasive, it is not feared that they injury the surfaces of the glass substrate and the address electrode.
摘要:
A plurality of discharge electrodes (23), (24) are formed on a first substrate (22) at an interval between the adjacent electrodes set to 50 .mu.m or smaller. A fluorescent layer (26) is formed on a second substrate (25 opposed to the first substrate (22). A sealed vessel (28) is formed by locating the first and second substrates (22) and (25) so that the electrodes (23) and (24) and the fluorescent layer (26) should be located on their inner sides. A predetermined gas is introduced in the sealed vessel (28) so that a pressure of the introduced gas should be within the range from 0.8 to 3.0 atmospheric pressure. Ultraviolet rays are produced by plasma discharge and make the fluorescent layer (26) emit light which is employed as illumination light.

To be able to efficiently and rapidly reduce noxious exhaust gas components after starting of an engine without impeding activation of a catalyst device, and moreover to be able to perform rapid separation of noxious exhaust gas components, an adsorption device 5 for adsorbing noxious exhaust gas components is provided downstream of a catalyst device constituting a main mode of operation of exhaust-gas purification, a honeycomb body carrying adsorbent is disposed within the adsorption device, a bypass passage is formed to one side of the honeycomb body, and a switching valve is provided upstream of those components. After engine starting, the switching valve opens, exhaust gas flows in the passage on the honeycomb body side, and HC is adsorbed by the adsorbent. Meanwhile, when exhaust-gas temperature rises and a condition wherein HC separates from the adsorbent is reached, the switching valve is closed, adsorption components which have become high in temperature due to exhaust gas heat separate from an passage between the downstream of this switching valve and the honeycomb body, and are refluxed via reflux passages and to an upstream side of the foregoing catalyst device.

An exhaust gas purification apparatus has a catalyst unit provided in an exhaust pipe of an engine and an absorbent provided downstream of the catalyst unit. When the engine is in a cool state, HC emitted from the engine is absorbed by the absorbent. After the engine is warmed up, the absorbed HC is desorbed by heat of an exhaust gas and returned to an upstream side of the catalyst unit the HC by heat of an exhaust gas.

A solid state imaging apparatus which prevents occurrence of small aperture fading by diffraction of light and can control the amplitude level of an image signal within a prescribed range. The solid state imaging apparatus employs a solid state imaging element such as a CCD. When the level of an image signal outputted from the solid state imaging element exceeds a predetermined value, a driving motor is driven to effect adjustment of an iris. The capacitance of a variable capacitance diode provided in a voltage converting section of the solid state imaging element is controlled in accordance with the amplitude level of the image signal to control the voltage conversion efficiency of the voltage converting section of the solid state imaging element so as to fix the level of the image signal.

A facsimile apparatus is provided which can enhance the operability and usefulness of portable image reading devices when transmitting documents and which allows effective utilization of the image reading device. The facsimile apparatus includes a main unit and a separable handscanner between which image signals and various control signals are transmitted using an optical communication technique. A document is scanned by a handscanner that generates signals representing the document image. The image signals are temporarily stored in an image memory and transmitted to the main unit when necessary. Depending on the hook state of the telephone, the main unit either transmits the received image signals to a remote station or records the image on recording paper. When the main unit receives image signals over a telephone network, the received image signals are transmitted to the handscanner for storage into the image memory when necessary. This is done for example, when the so-called memory reception mode is set or when a recording section in the main unit is in a non-normal state.
