Title: Two-color electrophotographic copying method
Inventor: ARAI AKIO
IPC: G03G15/01
Filed: 1984-04-24
Abstract: PURPOSE:To obtain a black-and-red two-color copy of superior picture quality by forming a red separated electrostatic latent image of an original on a P type photosensitive body and developing it with negative different-color toner, superposing and transferring the developed image on and to a red toner image which is fixed on a form previously, and performing fixation. CONSTITUTION:A photosensitive drum 1 to which the red toner image is already transferred is cleaned by a cleaning device 13 and charged positively by an electrostatic charger 7, but a photosensitive drum 2 is not charged so as to prevent its influence upon the photosensitive drum 1 as much as possible, The photosensitive drum 1 charged positively is irradiated with light reflected by a half- mirror 36 through a red filter provided to a filter turret 37 to obtain a positively charged electrostatic latent image of a colored part except the red part of the original. This electrostatic latent image is developed by the developing roller 6 of a developing device 4 which contains negative black toner and the obtained black toner image is superposed on and transferred to the red toner image of the original fixed on a form previously. The image is fixed by a fixing part fixing part and received by a paper discharge tray 42 through a couple of discharge rollers 41, thus obtaining the desired black-and-red color copy.

IPC: H01L27/10
Filed: 1989-04-03
Abstract: PURPOSE:To obtain a semiconductor device which has a negative resistance and operates at high speed and then makes integration to a silicon substrate easy by providing the 1st region of the 1st conductivity type, the 2nd region of the 2nd conductivity type which surrounds the 1st region, the 3rd region of the 2nd conductivity type which surrounds the 2nd region externally without coming into contact with the 2nd region, and the 1st conductivity type 4th region whose impurity concentration is high. CONSTITUTION:This device is equipped with the 1st region 2 of the 1st conductivity type, the 2nd region 3 of the 2nd conductivity type which surrounds the 1st region 2, the 3rd region 5 of the 2nd conductivity type which surrounds 2nd region 3 externally without coming into contact with the 2nd region 3, and the 1st conductivity type 4th region 6 whose impurity concentration is high. For example, as shown by Fig., an N-type impurity region 2 and P-type impurity region 3 are formed at an N-type semiconductor substrate 1 and then a hook region 4 is made up by joining the region 2 with region 3. Further, a P-type emitter region 5 and an N<+> type base region 6 are formed. This configuration lessens a resistance between emitter and hook regions and decreases the absolute quantity of minority carriers which are accumulated around the hook region 4 and then makes this device operate at great speed by reducing transition period from ON to OFF.

Title: Optical information recording and reproducing device
Inventor: ASHINUMA TAKAAKI
IPC: G11B7/004
Filed: 1984-04-25
Abstract: PURPOSE:To prevent intrusion of the disturbing noise from a recording system into a reproduced information signal and to reproduce exactly information with good quality by maintaining the unused recording system in a non-operating state during reproduction of the information. CONSTITUTION:The supply of a reference clock to each part of the recording system is stopped to maintain the recording system in the non-operating state in the stage of reproducing the recorded information signal from an optical disk 5. The detected output current value of the information on the MFM modulation reproduced photoelectromagnetically from the disk 5 by an optical pickup 4 is about 0.1muA and is supplied to a level comparator 7 after said value is supplied to a preamplifier 6 and is amplified to the level changeable to a TTL level. The reproduced information signal for the MFM modulation amplified to the TTL level is supplied by the level comparator 7 to a phase lock loop circuit 9 which generates the clock having the repeated frequency of the reference clock in synchronization with each bit of the MFM signal. The information signal for the MFM modulation amplified to the TTL level from the level comparator 7 is demodulated and is restored into the image information of an NRZ type in an MFM demodulator 8.

IPC: G06T1/00
Filed: 1993-04-08
Abstract: PURPOSE:To detect the features of several positions on a face and to exclude persons other than registered ones by providing this personal identification device with a position indicating part for inputting a specific part on the face to a prescribed frame in a picture input means. CONSTITUTION:A person intending to enter a room moves his face close to a mirror 2 so as to be identified and inputs an eye's position to the position indicating part 4. The picture input means 1 inputs the image of the face and stores the image in an image memory part 6 and executes horizontal scanning in order to search the eye's position and a luminance distribution detecting part 7 detects the distribution of binalized luminance levels in the position indicating part 4. A partial judgement part 8 judges each eye from the luminance distribution and a position specifying part 9 executes operation to find out the positions of respective eyes and a nose and length from each eye to the upper part of a mouth. A feature extracting part 10 computes the feature of the face of the person by using these data. Since the matching of the whole face is not executed, the capacity of calculation can be reduced and memory capacity can also be reduced.

IPC: G01C22/00
Filed: 1989-03-31
Abstract: PURPOSE:To eliminate the need that the memorandum of a route is read in course of driving and to attain the safety driving of a vehicle by successively guiding and displaying the route leading to a destination according to the running of the vehicle. CONSTITUTION:An odometer 1 measures the running distance of the vehicle and supplies it to a set circuit 2. The running distance which is shorter by as much as a prescribed value than the running distance to a running point which is previously set is arithmetically operated and held in the set circuit 2. Besides, guide information at the running point with respect to the running distance set in the set circuit 2 is stored in a display storage circuit 3. Then, every time the measured value of the odometer 1 arrives at the running distance set in the set circuit 2, the corresponding guide information is read from the circuit 3 and displayed 4 optically or with a voice. When the vehicle arrives at a position required to be confirmed which is displayed 4, the measured value of the odometer 1 is corrected to the corresponding set running distance by a confirmation circuit 5 based on a confirmation signal given by an operator. Besides, the measured value of the odometer 1 thereafter is corrected according to an error signal between the measured value of the odometer 1 obtained at that time and the set running distance.

Title: Memory access controller
Inventor: KADAIRA GIZOU
IPC: G06F17/16
Filed: 1986-04-09
Abstract: PURPOSE:To speed up an access to a storage device by continuously issuing an access request even if the memory unit of the 1st data overlaps with that of the 2nd data. CONSTITUTION:A part enclosed by solid lines indicates memory unit addresses (100-179) that the 1st data accesses, and the time when they are in use, while a part enclosed by broken lines indicates memory unit addresses (170-249) that the 2nd data accesses and the time when they are in use. A shadowed part indicates that the memory unit of the 1st data overlaps with that of the 2nd data from 170-179. The overlap of the memory unit eliminates that the start of the access request transmission of the 2nd data should wait.
