Title: Combustion ash elimination device for combustion preheating air supply system
Inventor: NANRI KEITA
IPC: F23J3/00
Filed: 1987-11-04
Abstract: PURPOSE:To facilitate the removal of combustion ash present in a wind box or the like and maintain a long term and stabilized operation of a boiler by installing an element provided with an air atomizing nozzle to a preheated air supply system for a pulverized coal boiler to remove accumulated combustion ash. CONSTITUTION:A combustion air is introduced into a gas type-air preheater 4 by way of an air duct 2, and a steam-type preheater 3 by a pressure blower 1, where heat exchange with high temperature combustion exhaust gas is carried out. The combustion air is introduced into a wind box 5 by way of an air duct 2. When heat exchange is carried out within the air preheater 4, combustion ash present in the exhaust gas is adhered to a heat exchange element and is subjected to leakage into the combustion air and accumulated within the wind box 5. To open a compressed air stop valve 12 installed to a compressed air piping 1 so as to remove the leak ash 14, the compressed air is atomized by the action of an element 13 provided with an air atomizing nozzle. Then, the leak ash 14 is scattered into the wind box 5 and introduced into a furnace 7 accompanied by the combustion air. Therefore, the leak ash can be removed, thereby allowing the furnace 7 to continue stabilized and efficient combustion.

Abstract: PROBLEM TO BE SOLVED: To make it difficult to manufacture illegal copies of a disk by adding first information to it based on the arrangement of barcode-formed grooves and also adding second information to it based on the modulation of the grooves themselves in accordance with their depths, directions, and groove bottoms. SOLUTION: This optical disk 1 has mainly an identification area forming barcode-formed grooves 4 and data area for recording data for recording data. The part of the identification area forming the barcode-formed grooves is composed of an aluminum layer 8 and an overcoat layer 9 successively laminated on a disk substrate. In this aluminum layer are formed non-erasable permanent grooves 4 transformed from ID information such as the production lot No. and serial No. of the disk. Such grooves 4 can be formed, for example, by irradiating the aluminum layer 8 in the identification area with a laser beam controlled ON and OFF corresponding to the barcode pattern while rotating the disk after a manufacture of the disk.

Filed: 1991-10-24
Abstract: PURPOSE:To obtain the communication system provided with a means identifying whether or not a stage of a repeater is a final stage and with a means identifying whether a receiver is a G2, G3 or G4 equipment and in which the repeater at the final stage implements processing of line density conversion/non-conversion according to the identified result to attain line density conversion at required. CONSTITUTION:The system consists of communication terminal equipments 1-8, repeaters 10-12 implementing multi-stage relay, identification sections 10a-12a identifying whether or not a repeater is at the final stage of relaying ancillary to the repeaters, and identification sections 10b-12b identifying whether or not a type (G2/G3/G4) ancillary to the repeaters 10-12 repeater of a transmitter and a type (G2/G3/G4) of a receiver are coincident with each other. Thus, no line density conversion is implemented in the process of multi-stage relay, the line density conversion/non-conversion is identified at a final stage and the conversion is implemented as required. Thus, since picture information is transferred without implementing undesired line density conversion in the relay process, picture quality deterioration due to accumulation of the line density conversion error is prevented and the time required for the line density conversion is reduced.

Filed: 1990-10-19
Abstract: PURPOSE:To enable the supply of sheets without being aware of a print format by an operator by enabling the binding hole position of a sheet to be detected using a mechanism which detects a binding hole position in a cut sheet printing device which detects the binding hole position of a sheet and controls printing process. CONSTITUTION:A binding hole recognition mechanism 2-2-1 is provided at four positions of a sheet feed mechanism 1-1. Holes are opened which fit the binding holes of a sheet, and a binding hole recognition bar 3-1 is introduced in the hole and a sheet with binding holes is stored by allowing the bar to pass through the holes. A binding hole position detection switch 3-2-1 is activated to be turned ON, if the binding hole position recognition bar 3-1 is set and the switch 3-2-1 is activated to be turned OFF, if the bar 3-1 is not set. These ON and OFF signals are transmitted to a printing device so that the exact position of binding holes is recognized by the printing device. Subsequently, print data is reversed for performing printing process, avoiding the binding hole, and if the binding holes of the sheet stored are improper, transport of the sheet is suspended to interpret that printing process is impossible.

Title: Combustion apparatus
Inventor: MATSUDA AKIRA
IPC: F23N5/24
Filed: 1986-11-21
Abstract: PURPOSE:To provide a combustion apparatus operated safely even if a switch is turned on by mistake by installing a key input circuit whereby the time required to operate after an ignition and extinction switch is pressed down is longer at ignition than at extinction. CONSTITUTION:A button 9 for ignition and extinction is pressed down. When it is pressed down for 0.2 second or more, a key input circuit 21 in a microcomputer 20 judges that a key input exists, but for less than 0.2 second the circuit judges that there is no key input. Therefore, even if the button 9 is touched for less than 0.2 second by mistake, the operation does not start. When the button 9 is pressed for 0.2 second or more to turn on a light touch switch 11, a motor cock 15 is set at an open position to open a solenoid valve 14 and start combustion. When the button 9 is pressed down during the combustion for 0.05 second or more, the combustion is stopped. Thus, as for the time for the ignition and extinction switch to operate, the switch is not operated if the button is pressed down for a longer time only at the ignition time and therefore, only when pressing down operation is applied surely on the button, the combustion is started and safety is secured.
