Title: Temperature control method for fixing device
Inventor: KUSUNE KAZUAKI
IPC: G05D23/19
Filed: 1992-06-04
Abstract: PURPOSE:To minimize the overshoot of the temperature which is produced when a fixing device of an electrophotographic system is heated. CONSTITUTION:A temperature T1 is set at a level lower than a target level and then the power supply of a fixing device is applied. At the same time, the system is so constructed that the estimated overshoot value can be corrected based on the heating time-temperature slope. Then, a fixing device temperature T2 is set with subtraction of the corrected overshoot estimated value. The final target temperature T3 is set when the temperature T2 starts to fall after the fixing device reached the level T2. In such a method, the overshoot of temperature can be minimized for the fixing device regardless of the levels of the voltage and the electric power.

Title: Brake force control device for vehicle
Inventor: YAMAGUCHI HIROTSUGU
IPC: B60T8/172
Filed: 1990-06-04
Abstract: PURPOSE:To effectively generate a brake force in an antiskid operation mode, and improve the performance of a brake force control device by controlling a unit load per travel wheel in such a way as to increase the load on a part of wheels undergoing antiskid control. CONSTITUTION:In controlling a brake force on a split road having a different surface mu right and left, a unit load per travel wheel on the lower road surface muis increased, when antiskid control is acting on the aforesaid wheel. For example, when a left front wheel 1L is on the lower road surface mu, a hydraulic active suspension controller 40 raises pressure in the pressure chamber 31 of a hydraulic cylinder 26FL via a pressure control valve 27FL for the left front wheel 1L, and the hydraulic cylinder 26FL is expanded, thereby increasing a force for a body to press the left front wheel 1L to the road surface. When a unit load per travel wheel load increases, a wheel slip decreases and the operation of antiskid control is retarded. Higher brake fluid pressure corresponding to the degree of such retarding can be used and, thereby, stable brake control can be realized, even in the case of braking on the split road.

Title: Sound multiplex broadcasting receiving circuit
Inventor: HIRANO MASAAKI
IPC: H04N5/60
Filed: 1986-06-23
Abstract: PURPOSE:To reduce disturbance due to video noise also at the time of receiving any broadcasting by connecting one ends of a resistor and a capacitor to each other of which the other ends are connected to right and left side output terminals respectively and earthing the node at the time of receiving two language broadcasting. CONSTITUTION:Since a control terminal 20 of a discriminating circuit 8 is held at a low level at the time of stereo broadcasting, a transistor (TR) 17 is helt at an off state. Thereby the left channel side output terminal 14 is connected to a right channel side output terminal 15 through a serial circuit consisting of a resistor 16 and a capacitor 19, so that a high frequency component is mixed and a video noise component is cancelled. Since only the high frequency of the signal component is mixed, the frequency characteristics are not deteriorated. Since the terminal 20 is turned to a high level at the time of two language broadcasting, the TR 17 is turned on through a resistor 18 and one side of the resistor 16 and the capacitor 19 is earthed. At that time, the high frequency band is dropped on the terminal 15 and video noise is reduced. Althrough the high frequency band of the signal is also dropped, no trouble is generated because the drop is generated in the subsound side. On the main sound side, the frequency characteristics are not deteriorated.

Filed: 1992-05-11
Abstract: PURPOSE:To prevent leakage of a control signal as noise by setting a frequency spectrum for various control signals between a mobile set and a stationary set to a band at the outside of a voice band in the talking state. CONSTITUTION:A MODEM 308 of a mobile set is prepared as a high speed MODEM 308a and a low speed MODEM 308b and they are controlled by a control section 306. The MODEM 808a is operated for other case than the transmission in the talking state through a speech channel and the FSK system of 1200bps or 2400bps is adopted for the modulation system. The MODEM 308b is operated for the case with the transmission in the talking state through the speech channel and the FSK system of 150bps is adopted for the modulation system. Since the control signal is sent from the mobile set to the stationary set in the talking state at a signal speed of 150bps whose frequency is at the outside of the audible frequency band, the leakage of the control signal as voice noise is prevented.
