Filed: 1982-01-29
Abstract: PURPOSE:To prevent the generation of uneven pitch, by using only a specific side of a rotary polygonal mirror, and controlling the amount of primary light in response to the reflected light, in an optical scanning device such as a facsimile performing reading and recording with laser light. CONSTITUTION:In starting a motor 4, a rotation detecting sensor 7 outputs a signal (9a) to an area designation circuit 8 when a surface of the rotary polygonal mirror 5 used for the recording reaches a predetermined position, and the circuit 8 outputs a carrier signal (d) to an optical moldulation driver 3. When the mirror 5 is rotated, a signal (b) is outputted from the sensor 7, the circuit 8 outputs an optical stabilization area signal (e) to a selector 9, and a data area designation signal (f) for a time for one line's share. An optical stabilizing control circuit 12 obtains a constant recording picutre at all times and outputs a data signal h' to the driver 3 in response to a sampling signal (i) from an optical detection sensor 6 in response to the amount of light of laser light. Accordingly, the driver 3 controls an optical moldulation element 2, and makes the amount of irradiated light constant.

Title: Check processing system for block command
Inventor: DOUGOME KAZUHIDE
IPC: G06F11/18
Filed: 1986-01-27
Abstract: PURPOSE:To improve the operability when a device is forcibly removed by providing a follower device state check means which checks applicability of follower devices and a follower mate system device state check means. CONSTITUTION:When a block command is received to set the single system of a duplex device under an inapplicable state, the state of a mate system device is checked against a follower device stored in a device to be blocked through a follower device state check part 14 and a follower mate system device state check means 15. If a magnetic drum controller DRC #10, for example has a fault, it is required to set a channel controller CHC #0 under a stand-by state. Thus the execution of a CHC block command is rejected if it is received since the DRC #10 of a follower device DRC #10 is already inapplicable. While an operator delivers the block command of the DRC #00 to set it under a stand-by state.

Title: Method and device for compensating crosstalk in optical recording and reproducing device
Inventor: IZUMIDA MORIJI
IPC: G11B20/10
Filed: 1989-01-27
Abstract: PURPOSE:To reduce the influence of a crosstalk from an adjacent track by using a signal regenerated from an adjacent track as a compensation signal and eliminating crosstalk component from the adjacent track included in a signal regenerated from a main track. CONSTITUTION:A main signal a2 is inputted to a summing terminal of an adder 14 as it is. A signal from photodiodes 1,3 corresponding to an adjacent track passes through delay circuits 10,11 and gain adjustment circuits 12,13 respectively and is inputted to the subtraction terminal of the adder 14. Thus, when the signal is subtracted from the main regenerative signal a2, a regenerative signal a14 compensating crosstalk is obtained. When the result is converted into a digital signal by an identification circuit 15, a signal a15 having almost no influence of crosstalk is regenerated. Thus, the adverse influence due to crosstalk from the adjacent track is considerably reduced.

Abstract: PURPOSE:To contrive preventing the reduction of saturated magnetization by preventing the forming of an oxide film on the surface of metal powder by dipping the magnetic metal powder in an organic solvent which contains 2- mercaptobenzimidazole. CONSTITUTION:If magnetic metal powder is dipped in an organic solvent which contains 2-mercaptobenzimidazole, the 2-mercaptobenzimidazole adheres to the surface of the magnetic metal powder, remains after the solvent is evaporated and covers the surface of the metal powder. This prevents the contact of the surface of the magnetic metal powder with oxygen and the oxidation of the magnetic metal powder is prevented by the earlier reaction with the oxygen of the 2-mercaptobenzimidazole which is more active with the oxygen than the reaction of the magnetic metal powder. The quantity of the 2- mercaptobenzimidazole contained in the solvent is desirable to be 1-3wt% ratio of the magnetic metal powder.
