IPC: G02B6/122
Filed: 1989-06-30
Abstract: PURPOSE:To prevent the scratch of waveguide surfaces and the failure of electrodes and to provide decreased guided wave losses and an improved yield by forming the electrodes on the surfaces of substrates formed with the waveguides, then forming protective films on these surfaces and polishing the films. CONSTITUTION:The waveguide 2 of a flush type is formed by a titanium diffusion method to be selectively executed on the surface of the substrate 1 formed of LiNbO3, etc. The electrode 3 having a three-layered structure of SiO2/Cr/Au is formed on the waveguide 2. The protective film 4 consisting of SiN is formed on the surface of the substrate 1 and the electrode 3 and two sheets of such substrates 1 are prepd. The two substrates 1 are superposed in such a manner that the protective films 4 face each other. The two substrates 1 in this state are inserted between polishing jigs 5 and are protected. While the two substrates 1 are kept held in the polishing jig 5, the end faces of the substrates 1 are polished by a grinding wheel, etc. The scratch of the waveguide surfaces and the failure of the electrodes are prevented in this way, by which the guided wave losses are decreased and the yield is improved.

Title: Image processing method and image processor
Inventor: ENOMOTO ATSUSHI
IPC: H04N5/253
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To print without omitting the part of an image of a main subject, even when a main subject such as the face of a person exists at an edge of an image read from a photographic film. SOLUTION: A lens type recorded on a photographic film is read (step 202) and pre-scanning (step 204) and fine scanning (step 206) are performed. Next, processing which extracts a part of the face of a person in the read image is performed (step 208). When aberration correction is performed, based on the extraction result, whether or not a face part is vignetted (image omission) is decided (step 210), when it is decided that the face part is not vignetted, normal aberration correction is performed (step 212), but when it is decided that the face part is vignetted, aberration correction processing is performed in the range, where the face part is not vignetted (step 214).

Title: Printing head
Inventor: YANO AKIO
IPC: B41J2/28
Filed: 1985-07-31
Abstract: PURPOSE:To speed up the operation of printing by a method in which leaf springs to support each wire are set biasedly in plural stages, the width is widened to one corresponding to the pitch of plural leaf springs, and the span of the leaf springs is shortened. CONSTITUTION:Since leaf springs 20 are set biasedly in plural stages, the width H of the leaf spring 20 can be widened to one nearly corresponding to the several times of the pitch of the springs 20. While widening the width of the leaf springs in this way, the span S is shortened. The needs to make the thickness T of the leaf spring smaller can thus be eliminated, and the spring constant can be kept at fixed value. By shortening the span S of the leaf springs while keeping the strength of the springs 20 and also the quality of printins, the printing speed can be raised.

Abstract: PURPOSE:To simlify the satellite mounting device by applying band split to a reception signal and allowing a transmission destination to exchange each split signal in an SCPC satellite communication system where exchange is performed at a satellite station. CONSTITUTION:After each reception SCPC multiplex high frequency signal of a reception multi-beam is given to reception input terminal 1(1-1-1-N) and the signal is amplified and frequency-converted at a reception section 2(2-1-2-N), the result is subjected to band split at a variable band pass filter 11 (11-1-11-N- N). Then the said band split signal is exchanged at each transmission beam to be connected. That is, the band split signal is frequency-converted at variable frequency converts 12(12-1-1-12-N-N), synthesized by synthesizers 13(13-1-13-N) at each band split signal having the same transmission beam to form a transmission SCPC multip signal.

In changing the connection channel number between the multi-beams of transmission and reception because of fluctuation of traffic, a controller 14 changes the band of a filter 11 and a converting frequency band of a frequency converter 12.

Abstract: PURPOSE:To provide an electric power supply device by which the occurrence of noise can be restrained by setting on-duty at 1:1 in simple circuit constitution. CONSTITUTION:On and off driving is carried out alternately on the first and the second transistors Q11 and Q12 in a half bridge type inverter circuit 12.
