Title: Oscillation circuit
Inventor: TODA MASANORI
IPC: H03L7/10
Filed: 1981-09-30
Abstract: PURPOSE:To reduce the phase lock pulling-in time while using a highly stable voltage controlled oscillator, by generating a large phase unlocked state in a phase locked loop forcedly until the phase lock is done. CONSTITUTION:A reference signal Vf1 is inputted to a frequency divider 11 via an AND gate 22-2, and a phase difference between a signal 1/n1-frequency- divided at the frequency divider 11 and a signal 1/n2-frequency-dividing a signal from a voltage controlled oscillator at a frequency divider 15 is detected at a phase detector 12. A phase difference discriminating circuit 21 discriminates whether or not this phase difference is within a prescribed range and when it discriminates as outside of the specified range, the circuit 21 starts a rectangular wave oscillator 22-1, switches the gate 22-2 almost periodically and interrupts the signal Vf1 from being inputted to the frequency divider 11. Thus, a large phase unlock is caused in a PLL forcedly, allowing to close the phase difference to zero rapidly. When the phase difference comes within the prescribed range, the circuit 21 stops driving of the oscillator 22-1 and an H output is kept being applied to the gate 22-2. An output of the detector 12 controls the oscillator 14 via an LPF 13 to output a signal Vf2 in a desired frequency.

Title: Air conditioner for vehicle
Inventor: SAKURAI YOSHIHIKO
IPC: B60H1/00
Filed: 1991-05-29
Abstract: PURPOSE:To relieve uncomfortability of a passenger by preventing air-conditioning control parameters from changing suddenly according to a sudden change in the quantity of solar radiation and outside air temperature when a vehicle goes into or out of a tunnel or the like. CONSTITUTION:When a vehicle enters a tunnel while driving outdoors in strong solar radiation, the quantity of solar radiation suddenly reduces from a large quantity of solar radiation condition. In that case, an outside air temperature change amount DELTATad is computed according to the time necessary for a change in solar radiation, and a value which is computed from the change amount is set as an outside air temperature Tad for computation (step 103, 104, 107, 109, 110) instead of a sensor detected signal Ta. The outside air temperature Tad for computation is assumed to change more slowly than the change in an actual sensor detected temperature Ta. Besides, the faster the speed of the solar radiation change becomes, the more largely the change is delayed. Namely, the change is made more slowly. Then when the set outside temperature Tad for computation becomes equal to the sensor detected temperature Ta, the sensor detected signal Ta is set as the outside air temperature Tad for computation (steps 112, 113, 107, 105, 114). The same control is carried out when a vehicle toes out of a tunnel.
