IPC: G03G21/00
Filed: 1994-02-18
Abstract: PURPOSE:To provide a fixing device capable of preventing the toner from offsetting on a fixing roller and the fixing roller from being accelerated in deterioration. CONSTITUTION:The cleaning roller 3 is freely rotatably attached to the top end of the supporting arm 5 freely swingingly disposed on the side of the fixing roller 1. The supporting arm 5 is suspended by the spring 8 and the solenoid 4 is connected to the supporting arm 5. At the time of fixing a single copy, the cleaning roller 3 is brought into contact with the fixing roller 1 while energizing the solenoid 4 for each copy (for every fixing respectively). And, in the case of fixing the consecutive copies, the cleaning roller 3 is brought into contact with the fixing roller 1 while energizing the solenoid 4 at the time of fixing the last copy. Moreover, at the time of standby of the fixing device, the cleaning roller 3 is separated from the fixing roller 1 while suspending the electric conduction to the solenoid 4.

Title: High pressure sodium lamp
Inventor: SAITO NAOKI
IPC: H01J61/54
Filed: 1989-01-31
Abstract: PURPOSE:To achieve a reduced starting voltage and a restarting voltage by sealing a given amount of krypton into a light emitting tube. CONSTITUTION:0.2 to 50 microcuries of krypton 85 per tube volume of 1cm<3> is sealed into a light emitting tube 1 contained within an outer tube 2, together with sodium, buffer metal and rare gas for starting. The radiations emitted from the krypton 85 cause electron excitation, resulting in improved starting and restarting characteristics. Actual measurements indicate that in cold condition, the average starting voltage is 2240V and the average restarting voltage is 3530V. This means that a lamp base 3 can be of ordinary screw-in type, and no special wiring is required for instantaneous reactivation, etc.

Title: Ecl logic circuit
Inventor: SUGAO TAKESHI
IPC: H03K19/086
Filed: 1990-01-31
Abstract: PURPOSE:To reduce power consumption and to attain high speed operation by providing an NPN transistor(TR) whose emitter is connected to an output terminal, an NPN TR whose collector is connected to an output terminal and a diode or the like. CONSTITUTION:When a rising signal is inputted to an input terminal IN, the TR 1 of a differential pair is turned on and the collector potential of a TR 2 is boosted. Then a current flows to a diode 12 in response to the collector potential and a TR 13 is turned on. Since the collector potential of the TR 13 is decreased, the TR 10 whose emitter is connected to the collector of the TR 13 is turned on. Consequently, since the collector potential of the TR 2 is decreased, the base potential of the TR 13 is lowered and a level at an output terminal OUT is kept to the falling state. Thus, a differentiation pulse is inputted to the base of the TR 13, a large current flows to the collector of the TR 13 momentarily, but a large current is not normally supplied, then the power consumption is reduced and high speed operation is attained.

Filed: 1989-01-31
Abstract: PURPOSE:To detect a paper passing error and to stop the operation of a paper passing means by permitting a recording medium detecting means which detects the presence of a photosensitive pressure sensitive medium in a feeding path to detect the presence of the paper passing error caused by the paper transmitting means. CONSTITUTION:A lever senser 18 which is the recording medium detecting means judges the presence of the microcapsule paper 13 and outputs a detecting signal, and the lever senser 18 demonstrates the function which detects the presence of the paper passing error. The paper passing is the operation which pulls out a leader at the top end of the microcapsule paper 13 and takes up by a take-up roll 15 through the feeding path. Then, the recording medium detecting means 18 detects the nonpresence of the photosensitive pressure sensitive recording medium in the feeding path of an image forming device, and the paper passing means passes the unused photosensitive pressure sensitive recording medium from a new cassette stored at the prescribed position in the device to the feeding path of the device. Thus, when the recording medium detecting means detects the presence of the paper passing error caused by the paper passing means and outputs the detecting signal, a control means operates and the operation of the paper passing means is stopped.
