Filed: 1989-06-26
Abstract: PURPOSE:To prevent misoperation by constituting a key switch turnably in two directions so as to light either a maintenance inspection-related display lamp or a manager-related display lamp in accordance with the turning action of this key switch. CONSTITUTION:When a key switch 4 is turned to a general side by a manager, a magnet lever 12 of a switch 4 is disengaged from a cover magnet 13a to open a cover 6, and when it is fully opened, a magnet switch 11, mounted to the cover, is actuated by a magnet 13b, mounted to a cover stopper 5, to turn on manager-related display lamps (on-lamp 8a, off-lamp 8d, on-fan 8b, off-fan 8e, normal 8c, each story stop 8f).

Title: Noise preventing circuit for parallel interface
Inventor: HARA KIMITOSHI
IPC: H03K5/1254
Filed: 1990-06-19
Abstract: PURPOSE:To obtain a noise preventing circuit for removing high frequency noise from a signal line by connecting the output sides of the 1st and 2nd NAND gates to the input side of an RS flip flop (FF) and connecting the output side of the RS FF to a data signal output terminal. CONSTITUTION:Since respective signals A to C are successively delayed in each clock period, the rectangular waveform of a noise part when the noise period is less than three clock periods does not appear on the output of a NAND gate G1. On the other hand, a data signal having the same level more than three clock periods is outputted from the NAND gate G1 as it is. Thus, the data signal including noise is inputted to this circuit, and when the noise period is less than three clock periods (the number of D flip flops), the data signal from which the noise removed is outputted. Thus, the circuit for removing noise included in the data signal can simply be constituted and cost reduction and IC formation can easily be obtained.

Abstract: PURPOSE:To rapidly and exactly adjust a spot diameter to the incident position of a laser beam on a scanner by moving and adjusting a semiconductor laser three-dimensionaly by a means for adjusting the laser beam. CONSTITUTION:Screws 14 are loosened and a 1st supporting member 13 is moved vertically and laterally relative to a base plate 11 to bring the spot position on a photosensitive drum 8 to an adequate position at the time of moving and adjusting the semiconductor laser within the plane perpendicular to the optical axis thereof. For example, two screws, which are positioned on the diagonal lines in the optical axis direction of the laser beam, among the screws 21 provided at 4 points of a 2nd supporting member 19 are turned in the tightening or loosening direction, then the remaining two screws are likewise turned and the 2nd supporting member 17 is moved in the direction attaching and detaching to and from the base plate 21 along guide shafts 18, 18 to correct the beam diameter. The semiconductor laser 2 can, therefore, be three-dimensionaly moved and adjusted. The beam of the same diameter as the beam diameter of the semiconductor laser 1 is thereby imaged to the prescribed position by independently adjusting the spot diameter and the spot position.

Abstract: PURPOSE: To reduce the amount of a polymerization initiator and to lower its cost, by using a complex reactor wherein a preceding tank reactor with the first and the second reaction zones is connected in series to a latter tank reactor having no division of reaction zone.  
     CONSTITUTION: A great deal of a raw material ethylene is fed to the first reaction zone of a preceding tank reactor and the rest of the raw material ethylene is added to a latter tank reactor. The raw material ethylene fed to the first reaction zone is polymerized in the presence of a polymerization initiator at 130W200°C under 1,000W2,800kg/cm 2  to give a reaction mixture, which is led to the second reaction zone of the preceding tank reactor and polymerized in a presence of a polymerization initiator at 210W280°C. The resulting reaction mixture is cooled by the heat exchanger between the two reactors to a temperature range from 120°CW20°C lower than the reaction temperature of the second reaction zone and transferred to the latter tank reactor. The reaction mixture is then polymerized in the presence of a polymerization initiator at 210W280°C under 1,000W2,800kg/cm 2  to prepare polyethylene. The high reaction temperature improves the efficiency of the polymerization initiator and reduces its amount.
