Title: Operational control of analysis for subterranean heat transfer
Inventor: NAKAMURA TADAO
IPC: G05D23/19
Filed: 1982-08-12
Abstract: PURPOSE:To simplify the analysis of a thermal behavior by a method wherein space dividing distances are equalized to the radius (d) of a cylindrical tube in both of (x) and (y) directions in case a heat conduction equation is converted into a differential equation. CONSTITUTION:The cylindrical tube 3, having the radius (a), is in a depth D0. Space differentiated amounts in the direction x, y are defined as DELTAx, DELTAy and the relation between them are defined as DELTAx=DELTAy=d. Dividing numbers to the terranean plane are D0/d which are changed into integers (m) by rounding to the nearest whole number. On the other hand, a depth is divided into (m) divisions by the distances of (d) and the length in the left and right is also divided into (m) divisions. According to this method, the setting of a boundary condition is facilitated. The subterranean heat conduction is analyzed in the planes x, y only under defining the axial direction of the tube as the (z) direction. The temperature T'ij at a time (t0+DELTAt) at a point (i, j) may be operated by a differentiated formula. Here, Ti,j is the temperature at the time t0, (u) is a DELTAt/d<2> and (a) is a subterranean heat conduction rate. Next, the operations are effected sequentially by adding the time of DELTAt, whereby the internal surface temperature of the tube at any time may be determined and, accordingly, the heat accumulating as well as the heat dissipating characteristics may be analyzed.

Title: Horizontal deflection circuit and flyback transformer
Inventor: MORIYAMA YOSHIAKI
IPC: H01F38/42
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To eliminate ringing in the horizontal deflection circuit by connecting a diode in parallel with a damper winding of the flyback transformer. SOLUTION: In this horizontal deflection circuit consisting of a horizontal deflection coil 1, a capacitor 2 and a transistor(TR) 3, a diode 8 is connected to a collector output 6 of the TR 3 and a damper output 7 of a flyback transformer (F8T) 4 by the polarity as shown by Figure. Through the connection of the diode 8 in this way, a forward voltage of the diode 8 clips ringing to avoid ringing. This is because the diode 8 is conductive when the ringing being a voltage between the collector output of the TR 3 and the flyback transformer 4 resulting from a charge/discharge current between the horizontal deflection coil 1 and the capacitor 2 exceeds the forward voltage of the diode 8.
