Title: Optical scanning device
Inventor: SHIRAISHI TAKASHI
IPC: H04N1/113
Filed: 2001-06-04
Abstract: PROBLEM TO BE SOLVED: To provide an optical scanning device capable of presenting a color image free from color slippage at a low cost. SOLUTION: As for the optical scanning device 1, Mj pieces of beam groups constituted of Ni pieces of beams are made incident on each reflection surface of a light deflection device 5 so that a distance between the beam groups may be monotonically increased from one end and the beam group at one end having the smallest distance between the beam groups may cross the beam deflected by the light deflection device. Thus, the image forming characteristics of the M group beam, that is, spherical aberration or a difference as for the fluctuation of the beam diameter and a difference as for the curving of a scanning line between the beam groups are reduced. Then, the deterioration of the image quality is prevented. Besides, the size of the optical scanning device is reduced.

IPC: G02F1/017
Filed: 2001-06-08
Abstract: PROBLEM TO BE SOLVED: To provide optical wavelength transforming equipment which reduces necessary signal optical power and transforms a wavelength with simple constitution. SOLUTION: The optical wavelength transforming equipment is provided with an electroabsorption modulator 1 having a multiple quantum well structure and a polarizer 2. A signal light beam and a probe light beam are inputted in the optical modulator 1. The optical modulator 1 is a polarization-dependent modulator.

Title: Gas adsorbing element and infrared sensor
Inventor: NAKAJIMA YASUSHI
IPC: G01J1/02
Filed: 2001-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a gas adsorbing element by which the quantity of getter is largely increased to reduce the exhaust time. SOLUTION: The element consists of a square metal thin plate 1 which is coated with a gas adsorbent and bent at four corners to form an octagon. Each section 3 formed by cutting the plate radially from the center toward the periphery of the plate except for the peripheral parts is folded at least one time toward the periphery. Since the central part where the getter material existed is cut out into plural sections 3 and folded toward the periphery to form an opening 4 corresponding to the position where the sensor chip is to be located, the getter material which was at the opening portion is fully utilized without waste. Accordingly, the loss of the utilization efficiency of the getter material will not be reduced even if the opening is enlarged, and it becomes possible to store a large amount of the getter material in a small space.

Filed: 2001-06-25
Abstract: PROBLEM TO BE SOLVED: To secure the reliability of a light emitting element such as an LED by performing emitting operation for AF auxiliary light normally to obtain focusing even in high-temperature environment. SOLUTION: When a shutter button 15 is half-depressed and an object is so dark that the LED 13 for auxiliary light should emit the auxiliary light, the LED 13 for auxiliary light emits the auxiliary light while a focusing lens 2 makes a scan and a microcomputer 9 obtains contrast information on the subject. Once a focusing position is determined, the LED 13 stops emitting the auxiliary light. When deciding whether the AF auxiliary light needs to be emitted according to lightness information, the microcomputer 9 obtains ambient temperature data on the LED 13 by a thermistors 14. Then the microcomputer 9 varies the light intensity of the AF auxiliary light according to the obtained temperature data. When the temperature is high, the current of the LED 13 is decreased to make the AF auxiliary light dark.
