Title: Receiver
Inventor: OGA MASATOSHI
IPC: H04B1/26
Filed: 1992-09-29
Abstract: PURPOSE:To reduce deterioration in the demodulation characteristic due to feedback of an undesired signal to an intermediate frequency amplifier circuit by using a filter having a different pass characteristic in the forward and reverse direction for an intermediate frequency filter of the receiver. CONSTITUTION:Part of power of an oscillation signal from a VCO in a PLL being a component of an FM demodulation circuit 21 in an IC 40 is leaked to an input section of an intermediate frequency amplifier circuit 9 in order to increase a passing loss in the reverse direction (from output to input) in comparison with a passing loss in the forward direction (from input to output) of an intermediate frequency filter 8. In this case, the feedback from the output to the input of the intermediate frequency filter 8 is prevented. Thus, when the PLL is in the lock state, the frequency of the signal inputted to a phase comparator in the PLL is equal to the frequency of the oscillation signal from the VCO. Thus, when the feedback quantity of the input to the intermediate frequency filter 8 is much, the filter characteristic is deteriorated, and then a differentiation phase characteristic, a differentiation gain characteristic, a group delay characteristic and a demodulation output frequency characteristic are deteriorated while the deterioration in the demodulation characteristic is reduced in this receiver.

Abstract: PROBLEM TO BE SOLVED: To obtain a digital copying machine system which executes the pre- rotation start of a rotation deflecting means device only in the case where the usable function requires the rotation deflecting device means when the use of a device is made possible by setting a key card to a user limiting device. SOLUTION: When the key card is set in the key card device, the function that the set key card is permitted is checked. In the case of the card with which the use of a printing function of a copy, printer or the like is permitted, judgment is made that the pre-rotation of a polygon motor is needed (S21; Y) and whether the polygon motor is already under rotation or not is judged (S22). Unless the motor is under rotation, the pre-rotation of the polygon motor is executed so as to be ready for printing operation (S23). On the other hand, if the pre-rotation of the polygon motor is not needed (S21; N), whether the polygon motor is under rotation or not is judged (S24) and the rotation of the polygon motor is stopped (S25) in the case under rotation.

Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To lengthen the lamp service life, and reduce restarting voltage by prohibiting a restart of arc tubes by a restart control means until a restart prohibiting time passes after a start of one arc tubes in plural arc tubes is started. SOLUTION: A starter 18 has a filament 20 heated by current-carrying at starting time and starting bimetal 19 to be suddenly turned off by opening a normally closed contact point when thermally deformed by being heated by this. A function of prohibiting a restart for a prescribed time (for example, six minutes or more) is imparted to the bimetal 19 itself, and when the always closed contact point is opened by being thermally deformed, for example, if a restart prohibiting time not less than six minutes do not pass after its opening operation time, thermal deformation is removed by natural cooling, and it is restored to the original form, and the contact point cannot be closed. Therefore, arc tubes 4 and 5 cannot be restarted in the restart prohibiting time.  Therefore, contact point failure of the bimetal 9 is prevented, and an increase in starting voltage can be is restained or prevented, and the service life of a high pressure discharge lamp can be lengthened, and reliability can be improved.
