Title: Vertical magnetooptical recording and reproducing device
Inventor: MATSUI TSUTOMU
IPC: G11B5/127
Filed: 1985-10-23
Abstract: PURPOSE:To reduce the weight of an optical head and to attain tracking control with high accuracy by reading the information in a reproduction mode by means of the laser light beam and also making use of the magneto-optical effect. CONSTITUTION:In an information recording mode a prescribed signal current is flowed to a recording medium 6 set between a main magnetic pole 10 and an auxiliary magnetic pole means 7 from a coil 7a of the means 7. Thus a magnetic domain is formed to the medium 6. While in an information reproduction mode the information given from the minute domain of the medium 6, i.e., the tracking and information signals are added together via the pole 10. Then the information converted into the magnetic signals is copied with magnification to a magnetic copy film 9b. Then the laser light beam which is transmitted through the film 9b and reflected by a reflecting film 9a together with its turned polarizing surface is fed back toward an optical system 2 in the form of a return light beam and then extracted via a prescribed optical path in the form of the tracking and information electric signals respectively.

Title: Image forming device
Inventor: KIKUCHI SUSUMU
IPC: G03G15/00
Filed: 1985-10-25
Abstract: PURPOSE:To positively prevent toner from sticking on an electrostatic charger, discharger, or image formation optical system, etc., by allowing an air flow to run in a peripheral space extending from the downstream side of a cleaning member to the upstream side of a developing device in the rotating direction of an image carrier. CONSTITUTION:When a fan 26 rotates, scattered toner produced in a developing device 2 and magnetic toner suspended nearby pass a space position opposite a photosensitive drum 1 together with the air flow because of the suctional force of the fan. In this case, they are attracted by a magnet body 20 and then only air is sucked into a unit body 4. Part of the air sucked into the unit body 4 passes through the grid part 6a and discharge wire 6b in the charger 6 to clean up them and is then discharged from the unit body 4 through a discharge hole 18. The remaining air passes through the periphery of a photoconductor 5 and discharged from the unit body 4 through a discharge hole 18. A discharging lamp 17, on the other hand, is cleaned up with the cleaning air which is right after being discharged through the discharge hole 18. A magnet body 16 catches toner fallen by a cleaning blade 13 and prevents it from scattering out.

Filed: 1989-09-13
Abstract: PURPOSE:To inform an origination-side of a registered content by storing an absence content which is registered from a telephone set into a memory at the time of leaving a seat and informing a calling subscriber of the absence content stored in the memory when there is an incoming call. CONSTITUTION:A subscriber A registers a 'holiday' as the example of the absence content, for example. In such a case, data on 'holiday' is registered in the registration area of the subscriber A of the memory 5. When the subscriber A is in an absence registration state and a subscriber B makes an origination to the subscriber A, a central processing unit 4 reads the registration content of the subscriber A from the memory 5 and displays the data in the display window of the multifunction telephone set of the subscriber B as 'holiday'. Thus, the registered content is informed to the origination-side by allocating the absence content to function keys.
