Title: Control device of burner
Inventor: UCHIDA TAMIYA
IPC: F23N5/00
Filed: 1990-11-13
Abstract: PURPOSE:To control the amount of combustion and air flow rate according to temperature change with a single type of control device by changing the model or specification of the device based on the combination of a microcomputer's input port. CONSTITUTION:Various signals which correspond to the combination of connection means 40 to 44 are inputted into an input port of a microcomputer IC1 (3). The previous combination allows equipment model or specifications to be changed over so that the selection of device model, say, A or B may be determined by means of a device model change over signal. Then, the specification is classified so as to use C or D by means of a specification change over signal. The both signals are used for common service where they are used to monitor an important treatment, such as burning state. On the other hand, when they are used for the air capacity or display service, the treatment is shifted in response to a change over signal once again. Since connection terminals 52 and 55 connected with a second driver IC10 are different from each other in terms of display circuits blocks 50 and 52, they are classified into the connection terminals 52 and 55. In a similar manner, connection terminals 54 and 57 are different in terms of operation circuit blocks 51 and 53 so that they are classified into connection terminals 51 and 53.

Title: Arc-extinguishing device
Inventor: KUNIMOTO YOICHI
IPC: H01H73/18
Filed: 1989-11-27
Abstract: PURPOSE:To prevent re-bridging of an arc caused by the ionized gas by locating a bridging preventing plate in the center of the rear side of an arc-extinguishing grid. CONSTITUTION:An arc-extinguishing device comprises an arc-extinguishing grid 1 made of multiple grid plates 3 laminated with spaces and a bridging preventing member 2 located in the exhaust side of the arc-extinguishing grid 1 and having a bridging preventing plate 4 in parallel to the grid plates 3 and positioned in the nearly center of the laminating direction. Consequently, when an arc enters to the arc-extinguishing grid 1, the arc is cut by the grid plates 3 to be extinguished, and the ionized gas is exhausted to the rear side of the arc-extinguishing grid 1. In this, case, since the bridging preventing plate 4 is located at the center of the rear side of the arc-extinguishing grid 1, re- bridging of the arc by the ionized gas can be prevented.

Title: Image transmission system
Inventor: YUASA HIROYOSHI
IPC: H04N19/423
Filed: 1986-12-23
Abstract: PURPOSE:To improve the accuracy of the gradation component of an image data and to upgrade the transmission rate by FM-modulating an FM signal after band-compressing its amplitude, and transmitting it through an analog telephone line. CONSTITUTION:A video signal from a TV camera 1 is subjected to a D/A converter 2 and supplied to a frame memory 3. Then its amplitude is band- compressed by a gradation conversion table and thus made a logarithmic signal, and this signal is subjected to a D/A converter 4, and supplied to an FM modulator circuit 5. Therefore, even if the signal is FM-modulated with a small amount of frequency shifting, the accuracy of the gradation component of a video signal is kept high, also, the gradation component does not deteriorate even the scanning speed is increased. As a result, the gradation component accuracy of an image signal that is transmitted through an analog telephone line is improved, and at the same time, the transmission rate can be upgraded.

Title: Fluid force calculation method, and fluid force calculation device and program recording media
Inventor: OKADA SHINZO
IPC: B63B35/53
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To obtain a floating body force calculation method that allows calculation to be completed within a short period of time by dividing a floating body into congruent elements and, for a plurality of pairs of elements for which the same integral value among elements is obtained, performing Green's function calculation with only one of them and applying this value to the remainder. SOLUTION: A floating body is divided into congruent rectangular elements and data of Nx×Ny coordinates are obtained. Then, an integral value among elements in a Green's function G(ΔX, ΔY) is calculated using coordinates information of two elements which satisfy the following requirements, i.e., the difference in element numbers in X direction is r and the difference in element numbers in Y direction is t. The results of this calculation are stored in memory as F(r, t) (S215). After calculation of F(r, t), processing is terminated when r becomes 'Nx-1' (S216; YES) and the value of variable t becomes 'NY-1' (S217; YES), i.e., calculation of Nx F(r, t)'s is completed for Ny t's from 0 through Ny-1. This reduces the number of calculations actually made of Green' s function integral values among elements, ensuring a high-speed calculation of fluid force.

Abstract: PURPOSE:To give information that a line wire call becomes possible when the line wire call terminates by transmitting an alarm sound generation instruction to a slave unit which is stored in a line wire origination reservation slave unit storage means and which makes the call while a telephone line is closed after the line wire call terminates. CONSTITUTION:When the certain slave unit is busy in a line wire, a line close switch 17 closing/opening the telephone line of a master unit is closed. When there is the call from the slave unit in such a state, the master unit transmits a busy tone to the slave unit through a communication control part 26, a transmission/reception part 25 and an antenna 24. Then, that the termination of the line wire call is informed is supervised. When termination-is informed, a central control part 20 connects a radio line with the slave unit again through the communication control part 26, the transmission/reception part 25 and the antenna 24. The central control part 20 transmits the alarm sound generation instruction to the slave unit which makes the call first while the telephone line is closed. Thus, the caller of the slave unit can learn that the line wire call becomes possible.
