Title: Optical fiber depolarization device
Inventor: BURUUSU MISHIERU NIYUUMAN
IPC: H04B10/135
Filed: 1993-12-24
Abstract: PURPOSE: To provide a non-polarized amplified natural light emission of a long wavelength from input signals and to measure the polarization-dependent loss of an optical element by using an unpumped doped optical fiber in a length which is sufficient for absorbing input polarization signals. CONSTITUTION: An erbium doped optical fiber 36 is used as an optical amplifier in a light transmission system. The amplification of signals between 1530 to 1565 nm is generated, when the erbium-doped optical fiber is pumped-by 1480 nm or 980 nm. When no input signal is present, the pumped erbium doped optical fiber generates a non-polarized light amplified natural radiation over a wide range of 1500 nm-1600 nm. The erbium-doped optical fiber 36 converts the received polarization signals into non-polarized amplified natural radiation. A power meter 38 receives and measures non-polarized light and decides the polarization-dependent loss of the optical element to be tested.

Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To obtain a detector eliminating detection error with the use of a photoreflecting sensor even if a detected body such as a base plate inclines or a reflection factor varies with the direction. SOLUTION: A light reflection sensor 2 detecting the existence of a to-be- detected body 4 and an arm 3 holding the to-be-detected body 4 are provided.

Abstract: PURPOSE:To operate an engine in which the operation of valve devices of selected those of a plurality of engine cylinders is rested, so that the engine may be operated in an engine cylinder resting condition even during operation of an air-conditioning device, by determining whether it is an all engine operating condition or an engine cylinder resting condition with the use of different maps for the period of operation of the air-conditioning device or for the period of unoperation thereof. CONSTITUTION:A valve mechanism 2 provided for intake and exhaust ports of an engine 1, is operated for opening and closing by a hydraulic drive part which may be changed over between an all engine cylinder mode in which valves of all engine cylinders are opened or closed, and a partial engine cylinder mode in which valves of only a part of the engine cylinder are opened and closed (valves of the remainder engine cylinder are rested), since the operating configuration of the mechanism 2 is set by a control part 3. The control part 3 sets the all cylinder mode or the partial cylinder mode in accordance with outputs from an engine rotational speed sensor 4 and a boost cylinder pressure sensor 5, being based upon a map. In this case, when a switch 6 for operating an air-conditioning device is turned on, whether it is the cylinder mode or the partial cylinder mode is determined wit the use of an air-conditioning determining map with which the partial cylinder mode can be made satisfactorily coping with an increase in volumetric efficiency in comparison with the determination between the all cylinder mode and the partial cylinder mode with the use of the first mentioned map.

Abstract: PROBLEM TO BE SOLVED: To prevent noise generated around a suction port part in which a bell-mouth type suction port ring is fitted. SOLUTION: A bell-mouth type auxiliary suction flow passage 37 is formed between an inner circumference of a suction port 4 of a main body case 1 and an outer circumference of a suction port ring 21.

Title: Image forming apparatus
Inventor: NISHIZAWA KATSUHIKO
IPC: B41J2/44
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To extend the life of a laser diode(LD) while shortening a fast copy- out time(FCOT) in an image forming apparatus performing pre-exposure. SOLUTION: Before pre-exposure is performed, the main motor for the rotational driving of a photosensitive drum is controlled so as to be rotated at a constant speed in the number C1 of rotations at a time of pre-exposure higher than the usual number C2 of rotations. In such a state that a scanner motor and the main motor are rotated at a high speed, a laser diode is driven to start pre-exposure to execute pre-exposure only for the time T allowing the photosensitive drum to make one revolution.  That is, since the main motor is rotated at a constant speed in the number C1 of rotations at a time of pre- exposure higher than the usual number C2 of rotations, the time T allowing the photosensitive drum to make one revolution becomes shorter than the time (t) allowing the drum to make one revolution at a time of the usual forming processing of an image and the time required in pre-exposure can be shortened. Accompanied by this, the cumulated lighting time of the LD and the time up to the completion of the printing of a first page can be shortened.
