Title: Waveguide type wave multiplexer
Inventor: KOISHI YOICHI
IPC: H01P1/212
Filed: 1989-09-07
Abstract: PURPOSE:To eliminate harmonic components effectively by connecting a tapered waveguide or a stepped waveguide whose cross sectional area is reduced gradually toward an end and terminating the waveguide with a radio wave absorbing member. CONSTITUTION:A tapered waveguide 4 is connected to the end of the waveguide type wave multiplexer. Thus, even when 2nd and 3rd harmonic components are caused with respect to fundamental waves whose frequencies are f1, f2 at outputs of 1st and 2nd transmitters 3a, 3b and they are leaked in a manifold 2, the leaked components are not cut off at an end 21 but led to a waveguide 4 as they are. Since a radio wave absorbing member 5 made of ferrite particles is connected to a termination part 41, when the components reach the termination part 41, the harmonic components are absorbed and reflection to the waveguide 4 is suppressed. As a result, the harmonic components are not reflected at the end 21 of the manifold 2, the standing wave is not formed and not led out.

Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To broaden a signal transmission band by adjusting the wavelength and light output of an exciting light source and setting the Raman amplification band to respective exciting light wavelengths so as to include all of signal light wavelengths. SOLUTION: Wavelength synthesizing couplers 12-1, 12-2 are arranged at both ends of an optical fiber transparent path 11 for transmitting the signal light of a wavelength λs.

Abstract: PURPOSE:To obtain a reader/writer excellent in an assembly characteristic without deforming a roller by providing a first roller, a second roller held at a position separated therefrom at the time of non-loading and a spring member directly supporting it. CONSTITUTION:A compressing roller 15 is supported to one end side of a torsion coil spring 30 on the back face side of a base 2a through a shaft 15a. This spring 30 supports the roller 15 on the one end side, the surface of the roller 15, does not contact the surface of a rubber roller 4 with no external force applied, but an interval t1 (0<t1<t2) smaller than the thickness t2 of a card 13 from the surface is set. Thereby, when the card 13 enters between the rotating roller 4 and the roller 15 separated by t1 therefrom, an elastic force pressing the spring 30 counterclockwise is generated. According to this elastic force, the card 13 is held between both the rollers and carried according to the rotation of the roller 4. In such a way, since the rollers 4 and 15 are separated at the time of non-loading, they are not deformed as a time elapses to reduce the number of parts for holding and pressing the roller 15 and improve the assembly characteristic.

Abstract: PURPOSE:To improve the offset adjusting accuracy by inputting a coded data in an offset adjusting circuit, using a decoder to select an N-channel transistor (TR) switch for the selection of the combination of resistive elements thereby decreasing number of inputs. CONSTITUTION:Plural resistive elements r1-rn are connected in series across offset adjusting terminals 2,3 of an operational amplifier 1 in the offset adjusting circuit, and the N-channel TR switches S1-Sn for selection are connected between a power supply and connecting point of the resistive elements r1-rn.

Abstract: PURPOSE:To obtain precise image data, by providig spacers made of materials which are softer than accumulative phosphor sheets so that the sheets are fed in satisfactory condition. CONSTITUTION:A roller 162 attached to the front end of a sheet check pawl 160 rolls on a topmost partition plate 125, and thereafter enters into an opening 128 in the partition plate 125 by means of the resilient force of a spring. Accumulative phosphor sheets A which are stored each in the gap between adjacent partition plates 125, are engaged with the sheet check pawl 160 one by one and are therefore fed toward rollers 26, 28. Therefore, during the movement of the sheets A, they are separated from the adjacent sheets, and further, the outer layer is separated from the partition plate 125, and the sheets A may be prevented from being damaged due to rubbing between the sheets themselves. Further, even if they make into contact with each other, no unfavorable condition occurs, since the partition walls 125 are made of materials which are softer than the sheet A.

Abstract: PURPOSE:To continue operation even when one of a plurality of power units is failed in an operation by separating a failure in operation spot from a hydraulic power unit corresponding to the failure in an operation spot or a control device for the hydraulic power unit when a failure in an operation is detected. CONSTITUTION:A motor drive signal S1 is outputted from a control device 11 to excite a relay 101a. In this case, a failure in operation detecting device 13 monitors the motor drive signal S1 and the contact of the relay 101a to decide as under-mentioned. Namely, when the contact of the relay 101a is closed, contact is normal and when the contact of the relay 101a is opened, contact is defective. In case the relay 101a is demagnetized by means of the motor drive signal S1, when the contact of the relay 101a is opened, contact is normal and when the contact of the relay 101a is closed, a contact is fused. As noted above, when a contact is poor in contact or fused, the failure in operation detecting device decides that a power unit 1 is failed in operation, a fail safe relay FS1 is demagnetized and the power unit 1 is separated.

Title: Illumination optical system for semiconductor exposure device
Inventor: IBA YOICHI
IPC: G03B27/72
Filed: 1987-09-17
Abstract: PURPOSE:To uniformize the illuminance of the whole surface of a reticle and to maintain the NA of an illumination light to the reticle constant irrespective of its azimuth by disposing an image rotator between a light source and an integrator in an illumination optical system for a semiconductor exposure device, and rotating the rotator at an optical axis a center during exposure. CONSTITUTION:A luminous flux irradiated from an excimer laser light source 1 is incident to an image rotator 8 rotated at an optical axis as a center, and rotated. After the flux is enlarged by a beam expander 2, it is irradiated to the edge face of an integrator 3. Accordingly, even if the section of the flux radiated from the source 1 has any illumination distribution, if the time average is taken at the face of the integrator 3, an illumination having symmetrical characteristic with respect to the optical axis is performed. On the other hand, if the illumination distribution of the incident edge face of the integrator 3 is axially symmetrical, the intensity distributions of a plurality of light source images formed near the radiating edge face of the integrator 3 become axially symmetrical. Accordingly, the illumination distribution of the entrance pupil of a projection lens becomes axially symmetrical, and the NA of the illumination light to a reticle 5 becomes constant irrespective of its azimuth.
