Title: Automatic frequency control circuit
Inventor: HORIGUCHI YOSHINORI
IPC: H03H11/04
Filed: 1993-09-17
Abstract: PURPOSE:To provide an automatic frequency control circuit which can automatically control the center frequency with extremely high accuracy to the bell and reversed-bell filters that the turned into ICs. CONSTITUTION:In regard of the transfer function of a reversed-bell filter 30, a circuit constitution is deformed into a numerical expression, i.e., (1-transfer function of a BPF) and the secondary LPF output is obtained in the circuit. A secondary LPF acquires the phase characteristic so that a phase is turned by 90 deg.C at the center frequency, and a phase detector 34 applies the phase detection to the output of the secondary LPF to calculate the mean value. Based on this means value, the Gm amplifiers 32, 36, 37 and 40 are controlled by a Gm control circuit 42. Then the mean value is fed back to the filter 30 and the frequency of the filter 30 is automatically controlled.

Abstract: PURPOSE:To prevent stagnation of foul air caused by turbulency of room air attributable to asymmetry in the flows of air ejected or in the temperature of walls by providing, above a lower supply-air outlet, an upper supply-air outlet in a wall at a position near the ceiling and by forming an air discharge opening in the middle of the ceiling. CONSTITUTION:There are provided lower supply-air outlets 6 each producing a velocity distribution, such as a radial distribution ranging from the horizontal direction to the vertical direction, at positions near two or four opposed edges at corners respectively between a wall 1 and the floor 2; an upper supply-air outlet 7 above each of the lower supply-air outlets 6 in the wall at a position near the ceiling 3; and an air discharge opening 8 in the middle of the ceiling 3. Foul air C polluted by smoking and the like flows upward toward the ceiling with a current of air from a lower supply-air outlet 6 and is discharged out of the room through the air discharge opening 8. If turbulency of flows of room air attributable to, for example, asymmetry in the flows of air ejected from lower supply-air outlets 6 or in the temperature of walls develops a force that causes the foul air C to swerve toward a wall 1 in a flow E or E' and tend to circulate instead of flowing upward in the middle, such a flow E or E' is counteracted by a current of air flowing from an upper supply-air outlet 7 to the air discharge opening 8 and forced toward the discharge opening 8.

IPC: G06F11/32
Filed: 1988-09-19
Abstract: PURPOSE:To easily explicate the factor of a fault by providing a means which transmits a fault message to a host station as long as a communication channel is normally connected to the host station in case a fault occurs during an initializing action of a terminal equipment and therefore displaying the fault message received by the host station from the terminal equipment on a display device. CONSTITUTION:When a power supply is turned on for a printer 1 buried into a desk in a fault information display system, a mechanical initializing action is first carried out. Then it is decided whether the initializing action is through in a normal way or not. If so, a preparation end message is sent via a communication channel 4 so that an on-line state is set. In the case of the initializing action through in an abnormal state, a fault message showing the contents of the fault is transmitted via the channel 4. Then a controller 2 displays a state showing the unconnection of the printer 1 on a display device 3 and then displays the fault contents on the device 3 with reception of the message from the printer 1. Thus the fault contents can be easily explicated.
