Title: Charge erasing device
Inventor: TOMOSADA MASAHIRO
IPC: G03G15/04
Filed: 1985-04-11
Abstract: PURPOSE:To decrease the number of parts of a lighting circuit and to eliminate an irregularity in erasure even when LEDs are used as the light source of a charge erasing device by turning on all light emitting elements corresponding to the erasure width of a charge at the same time at the start and/or end of the illumination of the light emitting elements. CONSTITUTION:The charge erasing device 1 is equipped with light emitting diodes LED1, LED2...LEDX as light emitting elements and those LED1, LED2...LEDX are arrayed opposite the surface of a photosensitive drum 3 to the overall axial width of the photosensitive drum 3. When a charge is erased to the overall axial width of the photosensitive drum 3, pulses are applied to bases of transistors TRa, TRb... and TR1, TR2... to turn on all the LED1, LED2...LEDX at the start and end of illumination. In this case, dynamic illumination is employed to turn on the LEDs in groups (a), (b), and (c), group by group. Consequently,the photosensitive drum 3 is discharged uniformly and electrostatically.

According to this, the recycle treatment of the magnesium product 1 or the relieving treatment of a surface treatment defective product can be easily performed at a low cost.
Patent JP-S60219986-A (JP)
Title: Controller for induction motor
Inventor: SHIMIZU HIROKI
IPC: H02P21/36
Filed: 1984-04-17
Abstract: PURPOSE:To detect a malfunction irrespective of the absolute value of a rotating speed by comparing the output of a saturating circuit with the varying rate of the output of a rotation detector. CONSTITUTION:If a negative torque load is inverted when a motor stalls, the output voltage of a rotation detector 12 becomes negative. When it increases at the negative side, the output of a saturating circuit 3 does not vary with positive since the increase in the speed is instructed, but the output of a differentiator 13 becomes negative. Accordingly, the outputs of comparators 14a, 14b respectively become high nd low, and the outputs of comparators 15a, 15b respectively become low and high. Therefore, the outputs of exclusive OR circuits 16a, 16b become high, the output of an OR circuit 17 becomes high to operate a timer 18. Since the stall is not recovered even if the prescribed time set in a timer 18 is elapsed, the timer 18 generates a malfunction signal to warn the stall.

Filed: 1989-03-30
Abstract: PURPOSE:To improve step coverage and to improve recording and reproducing efficiency by forming the prescribed part of the substrate material of a lower magnetic layer to a projecting shape and magnetically coupling the lower magnetic layer and an upper magnetic layer in this projected part. CONSTITUTION:The part of a nonmagnetic film of SiO2, etc., formed on a substrate 1, exclusive of the parts corresponding to magnetic contact holes 9, is removed by an etching treatment to form the projecting substrate 11 for the lower magnetic layer at the film thickness which is equal to the thickness of an inner gap (coil + insulating layer) to be formed thereafter. Both side faces of the projecting substrate 11 for the lower magnetic layer are executed of taper-etching and are thereby formed to a tapered shape. The lower magnetic layer 2 consisting of a magnetic metallic film is then formed on the substrate 1 and the substrate 11 for the lower magnetic layer. The upper magnetic layer 5 is, therefore, no need for bestriding the step on the contact hole 9 side and the film thickness of the lower magnetic layer 2 is not increased. The step coverage is improved in this way and the recording and reproducing efficiency are improved, by which the increase in the crosstalks is suppressed.

Abstract: PROBLEM TO BE SOLVED: To calculate a copying charge by counting and converting it similarly to the case of ordinary copying even in the case of the back-side copying of paper whose one side has been already used for copying by putting a mark showing that the paper is copying paper the front side of the copying surface of which has been already used for copying. SOLUTION: The copying paper 9 fed by a carrying belt 15 is detected by a copying paper detecting sensor 25 at the preceding stage of a fixing device 16, and a marking means 24 puts the mark showing that the paper 9 to which copying has been performed is the paper the front side of the copying surface of which has been already used for copying on the paper 9, which is ejected to a copying table 18. In the case of performing the back-side copying by using plural sheets of copying paper on the front side of the copying surface of which the mark is put, the paper 9 is piled up in a paper supply cassette 8 in a state where the mark is turned downward.  Whether or not the mark is put on the paper 9 fed from the cassette 8 by a paper supply roller 7 one by one is detected by a back-side mark detection sensor 21 so as to discriminate whether or not it is the copying paper the back side of the copying surface of which has been already used for copying.

Title: Amplifier circuit
Inventor: MAEHARA EIJU
IPC: H03G3/30
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To surely obtain the effect of overcurrent protection by forcibly turning off a switching transistor(TR) when an overcurrent flows to a load. SOLUTION: When an overcurrent flows to a load due to any fault, flowing of an overcurrent is fed back to a control circuit 11 by a load current detection signal DK. Then after the control circuit 11 recognizes it, the control circuit 11 provides an output of a drive signal DD denoting forced turning-off of a switching TR SW11, a driver 12 boosts a level of a gate of the switching TR SW 11 up to a prescribed power supply voltage (+Vc) forcibly based thereon to turn off the switching TR SW11. Since no power supply voltage (+Vc) is applied to the amplifier 14, the overcurrent protection is attained for the load and the circuit.

Title: Receiving antenna with switch and radio terminal equipment using the antenna
IPC: H04B1/44
Filed: 1992-03-31
Abstract: PURPOSE:To prevent interference between antennas with each other at the time of transmission by changing the impedance of the receiving antenna. CONSTITUTION:When a switch 21 connected to a patch antenna 20 for reception is turned off at the time of reception, the length of a band-shaped conductor 20-1 is specified to lambda/2 and resonated to transmitted radio waves at a frequency lambda. The received signals generated by the resonance are supplied from a feeding point through a feeder line 23 to an amplifier LNA 11-2. When the switch 21 is turned on at the time of transmission, the band-shaped conductor 20-1 and a ground plane 20-3 are conducted, and the feeding point impedance of the band-shaped conductor 20-1 is considerably changed. Therefore, serious mismatching with the amplifier LNA 11-2 is generated, and the signals of the patch antenna 20 sensing the transmitted waves from a transmitting antenna is extremely attenuated by the energy loss caused by the mismatching so as to considerably suppress the input to the amplifier LNA 11-2. Namely, the interference from the transmitting antenna to the receiving antenna is suppressed.

Abstract: PURPOSE: To obtain a polymer surface showing hydrophilicity and remarkable resistance against non-specific adsorption of protein by covering a surface of a medical or laboratory device with a solution of a prepolymer comprising ethylene oxide units capped with high molecular isocyanate terminals and then crosslinking it with water suitably. CONSTITUTION: A prepolymer is formed of monomer units in which at least 75% of the said prepolymer cosists of diol or polyol based on oxyethylene having a molecular weight of about 7,000-30,000, and in which polyol is reacted with an isocyanate to a hydroxyl ratio of about 1.8-2.2 in order to cap all hydroxyl groups with polyisocyanate.
