Title: Method for unlocking log information in log information reading
Inventor: UEHARA YOSHIYUKI
IPC: G06F11/34
Filed: 1989-03-20
Abstract: PURPOSE:To surely unlock a bus adaptor by setting up an internal interruption condition when an objective unit is locked at the time of reading out log information, and unlocking the unit by internal interruption processing. CONSTITUTION:When a log information reading instruction is outputted, a locking command is sent to the bus adaptor(BA) and a log area is locked. After setting up the log information by the CPU internal interruption condition, the log information is first read out. Even when abnormality is generated at the time of executing exceptional processing, i.e. at the time of reading out log information from the log area and storing the read log information in a software area during the period of reading out the log information such as the impossibility of storage for memory protection and the generation of a hardware failure, unlocking operation is executed. Since a CPU internal interruption is generated even by exceptional processing end in addition to the end of log information reading processing by previously setting up the CPU internal interruption condition, control is transferred to the internal interruption in any case and the BA is surely unlocked.

Title: Power circuit
Inventor: YAMAZAKI TAKASHI
IPC: H05B6/66
Filed: 1988-03-23
Abstract: PURPOSE:To prevent phenomena such as abnormal generation of heat, fuming, burning and the like in a power circuit due to a short circuit in a circuit including a load by connecting a protective rectifier to a capacitor in parallel as the discharge direction of the capacitor is the direction of easy flow. CONSTITUTION:A protective diode 10 is connected to a capacitor 6 in parallel and in reverse to the charge direction of the capacitor 6. This results in no influence to oscillation of a magnetron 8. For instance, when a diode 7 or the magnetron 8 is shorted, though the capacitor 6 is normally charged, when discharged in a following half cycle, a current is bypassed to the protective diode 10. This results in that the secondary side of a power transformer 2 is shorted and a short-circuit current is flows thereof. Accordingly, a large current also flows the primary side of the power transformer 2 so that a fuse 1 breaks the connection rapidly. Therefore, abnormal heat is prevented from being generated and there is no danger of fuming, burning and the like.

Abstract: PURPOSE: To improve the operability and to eliminate unevenness in the temperature of the water supplied by the gas boiler by a method wherein the stepless  capacity switching by a motor operation is made possible and the control of water  temperature can be easily carried out only by a dial setting.  
     CONSTITUTION: The desired temperature of the water supplied by the gas boiler is set by the dial of a controller 2. When the water temperature from a heat collector A is higher than the set point, the motor M is driven in one direction in response to a command signal inputted through the controller 2 from a temperature detector 1, so as to move an adjusting shaft 3 leftwards squeezing the opening of a governor 8 and decreasing the gas input. Thus, the water temperature is lowered to the set point. To the contrary, when the water temperature is lower than the set point, the motor M is driven in the other direction in response to a command signal inputted through the controller 2 from the temperature detector 1, so as to move the adjusting shaft 3 rightwards increasing the opening of the governor 8 and increasing the gas input. Thus, the water temperature is raised up.
