Title: Focus controller and method thereof
Inventor: SAEKI HIROSHI
IPC: G11B7/085
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To avoid the collision of an optical head with an optical recording medium even when a distance between the optical head and the optical recording medium becomes very short by increasing the value of NA of an objective lens. SOLUTION: When a loop off deciding circuit 31 decides that a focusing servo loop becomes off, a timer circuit 32 counts prescribed times by starting a timer. A driving voltage generating circuit 33 generates a driving voltage so as to separate an objective lens 14a from an optical recording medium 60 until the completion of counting for the prescribed time interval from the start of the timer of the timer circuit 32. Consequently, a focusing driver 40 performs control operation to separate the objective lens 14a from the optical recording medium 60 based on the driving voltage generated in the driving voltage generating circuit 33 when the focusing loop becomes off.

Title: Cleaning member for electrostatic charging device and process cartridge provided therewith
Inventor: KISU HIROKI
IPC: G03G15/02
Filed: 1992-12-26
Abstract: PURPOSE:To prevent a defective image because of that unnecessary toner adheres to a photosensitive drum from an electrostatic charging roller so as to intercept exposing light for the photosensitive drum from occurring. CONSTITUTION:The electrostatic charging roller 2 is brought into contact with the photosensitive drum 1, and a cleaning member 3 is allowed to abut on the roller 2. The cleaning member 3 is constituted by sticking a sheet layer 3b to a base substance 3a such as sponge, etc., with a double-sided adhesive tape 3d. The sheet layer 3b is formed from a film-like polyethylene terephthalate, for example, and is triboelectrified to be negative when it rubs the roller 2. The toner T1 hardly adheres to the sheet layer 3b because the sheet layer 3b has the positive polarity which is the same as the toner T1 even when the negatively electrostatically charged toner T1 adheres to the roller 2 from the drum 1 and further, even if it tries to adhere to the sheet layer 3b. Thus, a situation that the toner is accumulated between the roller 2 and the sheet layer 3b and drops and adheres to the drum 1, is prevented.

Title: Optical waveform shaping device
Inventor: EDAKAWA NOBORU
IPC: H04B10/556
Filed: 1999-12-27
Abstract: PROBLEM TO BE SOLVED: To realize an optical limiter function which operates at a high speed, employing a simple constitution. SOLUTION: Incident light beams (a wavelength λs) of an optical input port 10 are inputted into a port A of an optical circulator 12. Signal light beams (a wavelength λs) outputted from a port B of the circulator 12 are made incident on an end face 14a of an electric absorbing type optical modulator 14. A laser light source 16 generates CW light beams having a wavelength λp which is made different with respect to the wavelength λs of the signal light beams. The output light beams of the source 16 are made incident on another end face 14b of the modulator 14. The modulator 14 converts the signals having the wavelength λs into light beams having a wavelength λp with matched pulse peaks and the beams are outputted toward the port B of the circulator 12 from the end face 14a.  The circulator 12 supplies the optical pulse having the wavelength λp outputted from the modulator 14 to a saturable absorber 18 from a port C. The absorber 18 improves the quenching ratio of the inputted light beams and outputs the light beams to the external from an output light port 20.
