IPC: H02J7/04
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To realize quick charging by providing a current mirror circuit for the collector of a transistor where a capacitor is connected to an emitter to which an input signal is applied to a base and charging the capacitor with output current. SOLUTION: The capacitor 4 is connected to the emitter of the transistor 3 through a protection resistor 12 and it operates as a peak detector. A pin 13 is the pin of IC and the capacitor 4 is arranged out of IC. When the transistor 3 operates as the peak detector, charging current flows in the capacitor 4 from the emitter through the protection resistor 12 but it is not sufficient in quantity. Thus, the current mirror circuit 5 is arranged in the collector of the transistor 3 and current flowing in the current mirror circuit 5 is supplied to the capacitor 4 as charging current. In the current mirror circuit 5, plural transistors 15 on an output side are provided against the transistor 14 of an input side and output current is made to flow. The capacitor 4 is charged by the output current.

Title: Flame detecting device
Inventor: TAKEOKA MASAHIKO
IPC: F23N5/12
Filed: 1992-09-21
Abstract: PURPOSE:To detect a short between a flame rod and a burner unit and an abnormality such as oxygen deficiency, lift combustion and the like by checking a detected condition of a flame rod every point of time that a specified amount of oil having a possibility of oxygen deficiency is caused to burn. CONSTITUTION:When the amount of fed oil counted at a fed oil judging unit 15 reaches a specified level, a detection range switchover unit 18 switches over from a judging range to a short detection range in a flame condition judging unit 17. At the same time, a timer unit 20 operates to begin clocking, and when a time period clocked reaches a set time period, the flame condition judging unit 17 checks a flame current input from a flame detection unit 16 to suspend combustion when the frame current reaches an abnormal level due to beginning of lift combustion or oxygen deficiency. When the elapsed time does not reach a set level, combustion is suspended for the reason that a flame current input from the flame detection unit 16 is not detected by the flame condition judging unit 17 with respect to ignition or reaches an abnormal level of short detection.

Title: Facsimile broadcast receiver
Inventor: SUGA NOBUAKI
IPC: H01L33/00
Filed: 1990-09-19
Abstract: PURPOSE:To discriminate correct reception of a facsimile broadcast signal by detecting a frame synchronizing signal and lighting an LED even when no program is sent and no print-out is implemented. CONSTITUTION:A frame synchronization pattern is detected in the step n1 and when it is discriminated that the pattern is detected, a synchronizing signal is recovered and the synchronizing signal is outputted in the step n2. A synchronizing recovery detection signal is outputted in the step n3, then the step n4 is proceeded and the synchronizing recovery detection signal is used to light an LED. When it is discriminated that the frame synchronizing pattern is not detected in the step n1, the step is proceeded to the step n5, the recovery of the synchronizing signal is stopped and the synchronizing recovery detection signal is turned OFF in the step n6. The LED goes off in the step n7. Thus, whether or not the facsimile broadcast signal is correctly received is judged at a glance by observing the lighting of the LED.

Filed: 1992-09-22
Abstract: PURPOSE:To expand the soluble range of a combination minimization problem by constituting a discrete multi-level neural network device of a mutual connection type neural network and allowing the status transition of each neuron to base upon a specific characteristic specification. CONSTITUTION:An energy state storage part 1 is constituted of plural neurons which are mutually connected and an output signal from each neuron is fed back to another to store energy state and express a problem. An energy function determining part 3 expresses a problem to be solved as a minimizing problem as the weight coefficient and threshold of an energy function and an initial state determining part 5 determines the initial state of the neural network constituting the storage part 1. The state transition of each neuron is made to satisfy a specific expression setting up (2l-1)/2(N-1) as a threshold when N is a natural number and l is a natural number up to N-1. Consequently the soluble range of a minimization problem can be expanded to multi-level within the range of a standard quadratic function in addition to a bilinear function.
