Patent JP-H03272274-A (JP)
Title: Communication system for facsimile equipment
Inventor: IIDA SEIJI
IPC: H04N1/413
Filed: 1990-03-22
Abstract: PURPOSE:To improve the transmission efficiency of picture information by decreasing a bit number of sent picture information at a prescribed rate at the sender side when all picture elements of one line picture information are at a white level, allowing the receiver side to increase the subscanning speed at a prescribed rate when the picture information of all picture elements at a white level is received and to omit the recording of the picture information. CONSTITUTION:When all picture elements of one line picture information are at a white level, the sender side generates picture information whose total bit number is halved and sends the information. The receiver side replies an incoming call to inform a minimum transmission time corresponding to a required recording time per line of a plotter 2 to the sender side in response to the incoming call and receives the picture information after the execution of prescribed procedure. When all picture elements of one line picture information are at a white level, the recording paper is carried by one line pitch only at a higher speed twice the usual speed. In this case, the recording by a thermal head 2a for one line reception picture information is not implemented.

Title: Heat exchanger and manufacture thereof
Inventor: KITANI FUMIHIKO
IPC: F24H6/00
Filed: 1983-04-22
Abstract: PURPOSE:To prevent heating medium stagnating in one pipe from being overheated when the heating medium in one pipe stops circulating, by closely arranging two kinds of pipes which are respectively contacted to the walls of a combustion chamber, which composes passages for combustion gas, with the straight-lined part of each pipe forming the shape of a teardrop. CONSTITUTION:A pipe 21 for feed hot-water and a pipe 22 for air for heating rooms, being made in the shape of a teardrop respectively, are reversely combined with each other to form an oblong circle when their straight-lined parts are contacted to each other. Each pair of pipes 21 and 22 are inserted into the hole of a fain 4 which is punched to fit on the pair of pipes 21 and 22. The pipe 21 is located on the upstream side of the direction of flow of combustion gas. On the other hand, the straight-lined parts between both ends of each pipe 21a and 22a are contacted to each other in the same manner as the pair of pipes 21 and 22 being inserted into the hole of a fin 4. The pipe 21a for feed hot-water is contacted to the wall 3 of a combustion chamber with its straight-lined part, while the pipe 22a for air for heating rooms is contacted to the wall 3 with its wider end part of a teardrop shape. Because the straight-lined parts of each pair of pipes 21 and 22, and 21a and 22a are contacted to each other in such a manner as mentioned above, heat can be conducted well between each pair of pipes, so that the number of pipes in a heat exchanger can be decreased, as well as to prevent heating medium stagnating in pipes from being overheated.

Title: Method for detecting absolute steering angle of steering angle sensor for vehicle
Inventor: OSHITA SAIICHIRO
IPC: B62D15/02
Filed: 1989-03-22
Abstract: PURPOSE:To always accurately detect a steering angle by storing the value of the deviation of a reference position with an actual straight advance position in a non-volatile memory and calculating the steering angle from the reference position on the basis of the signal from a steering angle sensor to correct the same on the basis of the deviation value. CONSTITUTION:A reference position detecting point in the straight advance state of a vehicle is set to a reference position A and the deviation DELTAtheta with an actual straight advance state position B is stored in a non-volatile memory. Next, the pulse from a rotary encoder is counted by a microcomputer and corrected based on the deviation DELTAtheta to calculate an absolute steering angle which is, in turn, stored in the memory. Then, the next pulse is added to continue the detection of the absolute steering angle. Now, even in such a case that the power supply of the microcomputer is cut off by arrangement work and the memory of the steering angle disappears, since the deviation DELTAtheta is stored, a steering angle can be detected only by recognizing and resetting the position A. By this method, an accurate absolute steering angle can be always detected by simple operation.

Filed: 1987-03-25
Abstract: PURPOSE:To reduce load on a transmission node and a reception node and to accelerate transmission, by connecting a managing node which stores all of the data sent onto a transmission line to the transmission line. CONSTITUTION:The transmission node 2b, after transmitting a signal representing a transmission permitting request to the managing node 3 and receiving a permission signal, starts packet transmission, and transmits transmission data packets one after another. The node 3 holds those data packets in a data storage means 3b. Also, the node 3 checks a redundancy bit added in advance on the data packet as an error detecting means cyclically, and when a data error is found, it generates collision by outputting a carrier on the transmission line 1, and starts data transmission again. Meanwhile, the reception node 2a processes the transmission permitting request from the node 2b via the node 3, and starts data reception at a time when resouces required for the reception can be used, and transmits a transmission request to the node 3, and receives the data packet transmitted by the node 3. And the means 3b releases a storage area transmitted by a communication control means 3a.
