IPC: G02B6/122
Filed: 1986-06-12
Abstract: PURPOSE:To easily manufacture a tapered optical waveguide with good controllability by partially coating an acid on a ferroelectric substrate and subjecting the coating to a heat treatment. CONSTITUTION:Pyrophosphoric acid 3 is coated on the end of a +Z plate 2 of an LiNbO3 substrate l and is subjected to a heat treatment, by which an incident part 4 is formed. The pyrophosphoric acid 3 increases its viscosity and the liquid surface thereof spreads with an increase in temp.; therefore, tapered part 5 is simultaneously formed on the front end face of the light incident part 4. The pyrophosphoric acid 3 is then coated over the entire surface of the +Z plate 2 of the LiNbO3 substrate 1 and is subjected to the heat treatment to form the optical waveguide part 6. The above-mentioned stage is executed to the +Z plate 2 of the LiNbO3 substrate 1 on which a protective mask pattern of Ta is formed. The three-dimensional waveguide is thereby manufactured. Other acids are usable as far as the rate of evaporation thereof is low and such acids can be coated on the substrate surface.

Abstract: PURPOSE:To enable the dielectric breakdown strength of a multi-terminal type semiconductor device to be easily and accurately tested. CONSTITUTION:The measurement of a semiconductor device is carried out by a dielectric breakdown strength tester 5 before the joint 4b of a terminal 4 is separated. After measurement, the joint 4b is cut off from a terminal main body 4a. The tester 5 is connected to the joint 4b of the terminal 4 and a metal base plate 3 to carry out a dielectric strength test. Therefore, an operation where the terminal main bodies 4a are short-circuited to each other can be dispensed with, so that a test process is shortened and a dielectric strength test operation can be easily carried out. Furthermore, a voltage can be uniformly and surely applied to terminal main bodies, and dielectric strength tests of high accuracy can be executed.

Title: Communication terminal equipment with bft function
Inventor: TAKAOKA TATSUO
IPC: G11B31/00
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To prevent an inconvenience that a load of generating a transmission file is all invalidated by the presence of a defective sector by obtaining information of a total sector size in response to a type of a floppy disk, FD and executing all read tests before reading data. SOLUTION: When an FD transmission operation is started, information of all sectors is read while being stored in a memory for FD information and CRC check is conducted individually for each sector (CRC written in each sector of an FD is compared with a CRC at read). If a defective sector is detected on the way of the test, the executed processing is stopped and the storage to the FD is interrupted. Then a document file is retrieved and an image information memory in use is released. Through the processing in this way, meaningless transmission is prevented and then the communication cost is reduced. Since the transmission is executed only when all the sectors are not defective, efficient file transfer is attained.
