Title: Method of maintaining flame
Inventor: NAKAHARA TAKAFUMI
IPC: F23C7/02
Filed: 1979-12-14
Abstract: PURPOSE: To avoid the blowing out of an ignited fire and to reduce the smoke and NOX exhausted by supplying a primary combustion air from the surrounding of a fuel injection nozzle of a gas turbine combustor without imparting the supplied air with revolving component.  
     CONSTITUTION: A liquid fuel is supplied through the fuel injection nozzle 201 to a combustion chamber 202. A plurality of air inlets 203 are formed in the vicinity of the nozzle 201 by extending vanes 23 in the axial direction. The primary air is introduced by the guidance of these vanes 23 into the combustion chamber 202. This primary air is not imparted with the revolving component. Accordingly, the primary air flows along the axial line, thereby preventing the back flow of a secondary air fed through an air inlet 204. As a result, there occurs no stagnation zone or vortex zone 109, resulting in obtaining securely a stable flaming.

In a state that setting of a house code is awaited, a reception means 43 of the terminal 25a receives a house code setting command sent from a house code setting device 24 and gives it to the communication control means 42. Since the house code is not yet set, the communication control means 42 that receives this command stores the house code described in the command to a house code storage means 42 as its own house code. According to the operation above, the house code of the terminal 25a is set.

Title: Switching power source
Inventor: TANAKA HIDEHIRO
IPC: H02M3/28
Filed: 1986-07-09
Abstract: PURPOSE:To stabilize the output of a switching power source by connecting a field effect transistor with a rectifier at the secondary side of the power source, and controlling the ON time of the FET. CONSTITUTION:When a voltage is applied to the gate of an FET 35 through the secondary winding 32 of a converter transformer in a direction becoming ON, a charging current flows through an inductance 38 to a capacitor 39 to raise its output voltage. When the output voltage arrives at a reference voltage, a signal is produced from a detector 41 to turn ON a transistor 40. Thus, the FET 35 is turned OFF. When the FET 35 is turned from ON to OFF, the energy of the inductance 38 is charged through a diode 37 in the capacitor 39. Thus, the output voltage is detected by the detector 41 to control the FET 35, thereby stabilizing the output voltage.

Title: Calculation system for confidence of production rule
Inventor: TANAKA ISAO
IPC: G06F9/44
Filed: 1989-06-27
Abstract: PURPOSE:To attain an inference of uncertainty by calculating the confidence level showing that a numerical variable is equal to the mean value from the standard deviation of the numerical variable and subtracting the composite confidence level from the confidence level of a given binary event. CONSTITUTION:The mean value muij is substituted for a numerical variable Xij and at the same time the value yik is substituted for a binary event yij. Thus the value of a calculated arithmetic formula fi is obtained and then substituted for a relation Fi so as to obtain the Fi where a truth '1' and a falsity '0' are secured with fi>0 and fi<=0 respectively. Then the Fi is substituted for a logic formula g (Fi...) so that the value (g) of the logic formula is obtained. Meanwhile the confidence level c'ij is obtained from the standard deviation sigmaik of a numerical variable xik for the variable Xij which satisfies the conditions showing the xik is equal to the value muik. At the same time, the confidence c'i of each related event Fi is obtained from c'ik and the confidence level c'ik of a binary event yik. Then the confidence (c) of a rule conclusion part is obtained by multiphying the composite confidence level c' of the (g) by a confidence code P obtained from the form of the logic computation formula (g) and the value of the (g) is. As a result, a numerical variable including the uncertainty can be inferred together with the uncertainty including the event arithmetic result.
