Title: Improvement of copying machine
Inventor: SUDA MASAJI
IPC: G03G15/36
Filed: 1982-04-13
Abstract: PURPOSE:To transfer an image on the center of transfer paper by varying the point of the time when the forward end of the sensible image on an original comes to a transfer position and the point of the time when the forward end of the transfer paper comes at the transfer position in accordance with the difference in the size of the sensible image and the transfer paper thereby controlling the feed timing. CONSTITUTION:A sheet original OB stops once in the position where the forward end thereof is detected with a sensor 60. When the forward end of copying paper delivered from a feed base 29 prior to said detection arrives at the position of a sensor 76, the original OB is again conveyed by means of rolls 56, 57 and 61, 62 in accordance with the detection signal thereof. The position of the sensor 75 is l1+l2=l3 and the position of the sensor 76 is l1+l2=l'3+ 1/2(the length of B4 - the length of A4). The l1 denotes the distance from the sensor 60 up to the position where the light reflected from the original is detected, the l2 denotes the distance from the position 9 where the original image is exposed up to the transfer position, the l3 denotes the distance from the sensor 75 up to the transfer position and the l'3 denotes the distance in terms of the respective movement times of the original, the photoreceptor and the copying paper from the sensor 76 to the transfer position, respectively. The original is thus transferred in a desired position.

Title: Discharge excitation laser device
Inventor: INOUE MITSUO
IPC: H01S3/0971
Filed: 1987-03-17
Abstract: PURPOSE:To reduce load of a high-voltage switch, lengthen a life, heighten reliability and simplify constitution by incorporating a preparatory ionization means into a circuit for starting discharge. CONSTITUTION:A capacitor 1 for excitation is charged in advance at low voltage to a degree not to break down laser gas between main electrodes, while a first capacitor 11 is charged at high-voltage fully capable of causing breakdown. And, when a high-voltage switch 4 is turned on, the voltage impressed on the capacitor 31 is impressed on a gap 8 for preparatory ionization to break down the gap 8 for preparatory ionization and generate ultraviolet rays so as to perform preparatory ionization of laser gas between the main electrodes 5 and 6. At the same time, load of the capacitor 11 is shifted to a second capacitor 12 and a high-voltage pulse to be impressed between the main electrodes 5 and 6 becomes overvoltage sufficient to cause breakdown for a time to an extent of a time constant of a circuit 10 for starting discharge. Accordingly, uniform glow-shaped discharge 7 is generated between the main electrodes 5 and 6 combined with preparatory ionization by the gap 8 for preparatory ionization. Thereby, load of the high-voltage switch can be reduced simultaneously obtaining a long life of the switch, high-reliability and simplification of device constitution.
