Title: Zerographic image formation
Inventor: SAKAI TOSHIO
IPC: G03G15/26
Filed: 1978-04-28
Abstract: PURPOSE: To make it possible to produce clear copies without biasing a photosensitive element, which is considered to have less durability, by accomplishing a primary charging operation, a weaker secondary charging operation of the opposite polarity in the dark, and an image exposure.  
     CONSTITUTION: An insulating layer or a photoconductive insulating layer 12 having a different spectroscopic sensitivity from a photoconductive layer 13 containing a high molecular resin as a reinforcing agent is formed between a conductive substrate 11 and the photoconductive layer 13. If the photoconductive element thus prepared is charged in the bright to have a positive charges by a corona device, the positive charges are trapped by the layer 13 in the vicinity of the layer 12, and the negative charges are stored in the substrate 11. Then, the negative charging operation having a smaller absolute value than the potential of the primary charging operation is performed in the dark so that some negative charges are left in the substrate 11. If, under this condition, the exposure is accomplished through the original 2, the surface potential at the irradiated portion is either zero or slightly positive. On the contrary, the surface potential at the non-irradiated portion is left at a negative potential. The resultant latent image is developed by the negative toners so that the image having no surface blot can be formed.

Abstract: PURPOSE:To eliminate an inclined section attendant with the leading or trailing of a level and to obtain a binary signal correctly corresponding to a change of the level of a picture signal by dividing the picture signal into plural blocks individually carrying out the integration of the picture signal at every block and making the respective integrated value a slice level of the block. CONSTITUTION:After a picture signal VS is amplified by an amplifier 1, it is supplied to the first comparator 2. At the same time, it is guided to an integra tor 3, further digitized by an AD converter 4 to be supplied to the second compa rator 5. To other input end of the comparator 5, a predetermined reference black level signal SG is supplied, and a comparison output with the picture signal VS is stored in a memory 6 by one line. Accordingly, the picture signal in the memory 6 is delayed and outputted by one line, made analog in a DA converter 7, and thereafter inputted to the first comparator 2. If the output of an amplifier 1 is n-th line picture signal, the output of the DA converter 7 is a slice level signal corresponding to (n-1)-th line picture signal. The compa rator 2 outputs the comparison output of both the signals as a binary signal showing white or black.

Title: Piezoelectric driver
Inventor: NAKANO KATSUSHI
IPC: G01N37/00
Filed: 1995-03-10
Abstract: PURPOSE: To reduce the size of a driver while allowing high speed scanning of a probe by providing a drive member for scanning the XY plane between a Z-direction drive member and a supporting member thereby driving the probe three-dimensionally using two drive members. CONSTITUTION: A bimorph piezoelectric drive member 1 comprising two piezoelectrics pasted each other is fixed, at one end thereof, to a supporting member 5. The drive member 1 is fixed, at the other end thereof, through a block 6 with a Z-direction drive piezoelectric member 2 comprising three small and thin piezoelectrics pasted each other and a probe 3 is provided at the forward end thereof. Desired voltages are then applied to the two piezoelectrics of the member 1 thus driving the probe 3 in XY direction. Furthermore, a required voltage is applied to each electrode of the member 2 provided on a plane normal to the laminating direction of piezoelectrics thus shifting the position at the tip of the probe according to the irregularities of a sample.  Since the member 2 is required to move only the distance corresponding to the height of irregularities, the size can be reduced and since the resonance frequency is increased, even the irregularities varying at high speed can be followed up sufficiently.

Title: Automatic paper feeder
Inventor: TANIGAWA JUNICHI
IPC: B65H3/52
Filed: 1986-03-11
Abstract: PURPOSE:To make a positive feeding function in case of a paper feed block angle being small performable as well as to aim at the promotion of miniaturization, by attaching an elastic auxiliary plate to a feed roller concentrically and solidly in the tangential direction in a relative manner, and making a paper end so as to be guide toward the feed roller. CONSTITUTION:At first, since an original end 4a is not reached to a feeding position P1 of a feed roller 1, an original is fed out even if the roller 1 rotates, and it is merely raced, but a tip part of an elastic auxiliary plate 11 hits a paper feed board 3 and curved whereby energy is accumulated there. The auxiliary plate 11 to be further rotated comes off a notch part of the paper feed board 3, uplifting the original 4. With this operation, the original 4 is guided up to the P1 point along with rotation of the elastic auxiliary plate 11, and afterward it is fed to a sorting part P2 by the feed roller 1. Thus, the original being set nearby the paper feed roller is feedable without using a complex auxiliary roller mechanism, thus miniaturization in the device is attainable.
