Patent JP-H05240411-A (JP)
Title: Burner
Inventor: TAKAHASHI MUTSUHIKO
IPC: F23N5/12
Filed: 1992-02-28
Abstract: PURPOSE:To enable the stable detection of a flame current by providing a mixed gas guide which permits a mixed gas to bypass a pressure adJusting/flow smoothening portion and leads the mixed gas directly to a flame forming portion, in a burner which is controlled to keep safety on the basis of a flame current detected by a flame rod. CONSTITUTION:When a fuel gas is ejected from a nozzle 5, primary air is induced through a mouth part 4 into a mixing tube 3 to be converted into a fuel-air mixed gas and fed to the upper part of a burner 6. The majority of the mixed gas whose pressure and flow are adjusted and smoothened by the actions of a baffle plate 9 and a smoothening net 10, reaches a burner port net 8 and is ejected to the external side. A part of the mixed gas fed to the upper part of the burner 6 passes through a mixed gas guide 11 and is fed directly to the burner port net 8 without passing through the baffle plate 9 and the like. In case where a burning rate is set in a minute combustion range, pressure drop at an inlet port 11b of the mixed gas guide becomes less by the action of a flow rate control plate 12. As a result, the mixed gas is caused to flow relatively smoothly through the inlet port 11b, whereby a flame current is stably observed by a flame rod 13.

Title: Image data reading system
Inventor: SAITO SHOICHI
IPC: G06T1/00
Filed: 1988-02-24
Abstract: PURPOSE:To correctly read image data even when the setting position of an image drawing paper is dislocated by printing a special mark and an image area on the image drawing paper. CONSTITUTION:On an image drawing paper 7, a special mark 8 which is extremely rarely used for the original of the image and an image area 9 are printed beforehand. A control device 2 cuts only the special area of the image data delivered from an image reader 1, and delivers it to an image processor 3. The image processor 3 searches for the position of the special mark 8 out of the image data, obtains the image area 9 from a virtual original point, and cuts the original image area 9 from the image area delivered from the control device 2. Thus, even when the setting position of the original is dislocated, the necessary data can be correctly inputted.

IPC: H04L13/08
Filed: 1990-02-23
Abstract: PURPOSE:To relieve the load on a receiver side and to prevent missing in a reception data by informing the state of a reception buffer periodically to an opposite communication controller and limiting the data transmission in the case of congestion state depending on the information. CONSTITUTION:An idle reception buffer count circuit 17 in a communication controller 1 checks an idle buffer number of a reception buffer 15 and informs the number to a reception buffer information transmission control circuit 16. The reception buffer information transmission control circuit 16 sets an UI frame storing an idle reception buffer number to a transmission buffer 14 and sends it to an opposite communication controller 21. When a reception control circuit 22 detects the reception of the UI frame, the reception control circuit 22 of the communication controller 2 reads the reception data stored in the reception buffer 24 and when an idle reception buffer number is a prescribed value or below, the stop of data transmission or expansion of the transmission interval or the like is requested to the transmission control circuit 23 to limit data transmission. Thus, the congestion state of the reception buffer is relaxed to prevent missing in the reception data.

Title: Temperature control system
Inventor: NAKAJIMA TSUNEYA
IPC: F28D15/00
Filed: 1980-04-02
Abstract: PURPOSE: To equalize the temperature of individual shielding spaces with a simple construction by means of two heat pipes arranged in the opposite direction between the spaces.  
     CONSTITUTION: According to difference between the temperature read at a temperature detection control section 71 and the actual temperature by comparison, a heat generation command is sent to a heat generating section 31 to generate heat.  The heat is released at heat dissipating sections 31W51 in individual spaces 3W5  through a heat pipe 1. Detected with a temperature detection controller 72, it is  compared with the actual temperature to output a heat generation command to a  heat generating source 62. Then, heat is transmitted through a heat pipe 2 likewike  but in the opposite direction. This enables the control of a number of shielding  spaces by only two temperature detection controlling sections and heat generating  sources without difference in the temperature.

Abstract: PURPOSE:To easily classify recording paper sheets for each time of reception by making the recording paper sheet longer than a length decided in a communication mode when detecting the first, page of image information. CONSTITUTION:When the image information is received, a pulse motor 5 is driven backward according to a print start signal from a central processing part, and a recording paper sheet 4 is rewound only for a prescribed length. When a page detection part detects the first page of the received information, a dividing line is printed at the head part of the recording paper sheet 4 by a thermal head 7. Afterwards, the motor 5 is turned forward and the recording paper sheet 4 is conveyed. When the recording paper sheet is conveyed only for the fixed length set longer than the length of the recording paper sheet 4 decided in the communication mode by a feeding amount varying part, the head 7 starts printing the received information. When the first page of the received information is finished, the recording paper sheet 4 is cut by a cutter 8, and the cut received recording paper sheet 4 is exhausted into a paper exhaustion tray 3. Thus, the recording paper sheet can be easily and clearly distinguished for each time of reception according to the dividing line on the first page of a recording paper sheet 2 piled up at the tray 3.
