Title: Formation of polarization inverting structure of ferroelectric substance
Inventor: TAGUCHI AYUMI
IPC: G02F1/37
Filed: 1991-03-26
Abstract: PURPOSE:To surely form the polarization inverting structure without exerting any influence on the optical characteristics of the ferroelectric substance by locally heating only a position where necessary polarization inversion is caused. CONSTITUTION:An electric heating body 3 is adhered to the surface of ferroelectric crystal 1, made of, for example, single-area LiNbOa3(LN), which constitutes a main surface 1a in pattern corresponding to the pattern of the polarization inverting structure of the ferroelectric single crystal 1. This electric heating body 3 can be patterned by photolithographic etching after a conductor layer is vapor-deposited over the entire surface by sputtering. This electric heating body 3 is energized on to generate the temperature gradient of an abrupt temperature drop in the depth direction from the side of the main surface 1a right before the part of the ferroelectric crystal 1 where the electric heating body 3 is adhered. Consequently, an electric field is produced by pyroelectric effect at the heated part from the inside to the main surface 1a and a polarization inverted part 2 shown by an arrow (b) in the opposite direction from an arrow (a) is formed in the ferroelectric crystal 1 opposite the main surface 1a.

Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To miniaturize and make light weight the constitution of a lateral flow compensation device adopted, when an AC generator is operated in parallel with the other power source and to reduce manufacture man-hours. SOLUTION: A voltage source-type current/voltage converter 6, in which a magnetic circuit 6-1 and a hole element 6-2 are combined and whose power loss is extremely small, is adopted. The current signal of an AC generator 1 is converted into a voltage via magnetic flux. Voltage and the secondary side voltage of transformers 4 and 7 detecting generator voltage are added vectorially in arithmetic circuits 8 and 9A. Then, voltage is full-wave rectified and is changed into DC voltage and is outputted as a feedback voltage signal in a generator control system.

Title: Production of alloyed hot dip galvanized steel sheet having resistance to powdering property
Inventor: KUROKAWA SHIGEO
IPC: C23C28/02
Filed: 1989-03-16
Abstract: PURPOSE:To produce an alloyed hot dip galvanized steel sheet having resistance to powdering properties by performing Fe-based electroplating on the top layer of the alloyed hot dip galvanized steel sheet while controlling the etching amount of Zn to specified value. CONSTITUTION:Fe-based electroplating is performed on the top layer of an alloyed hot dip galvanized steel sheet. Thereby generation of a crater is prevented at a time of electrodeposition coating and also spot weldability is enhanced. At the time of performing the above-mentioned electroplating, the etching amount of Zn by an Fe-based plating bath is controlled to >=5mg/m<2>. As the controlling method of this etching amount, an auxiliary electrode is provided to a liquid touch part free from conduction of electricity and weak current is allowed to flow. Thereby chemical dissolving reaction due to plating liquid of low pH is effectively prevented. Generation of a crack is prevented on the alloyed plating layer and generation of powdering is prevented in press work by controlling this etching amount.

IPC: G11B27/10
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To allow the jump reproduction to a desired branch point by the easy operation during the reproduction of a DVD video disk of multi-story. SOLUTION: When the branch selecting instruction is given by the operator during the reproduction of the video disk, the instruction to change the reproducing position is outputted by a CPU (step ST8) so that the selected PGC(program chain) becomes the reproducing position. The reproduction is started from this reproducing position by a DVD reproducing part. Also, the history information is produced by the CPU (step ST9). When the jump instruction is given, the jump process is executed (step ST13) based on this history information. The jump to the desired position is attained by keeping to store the branching place and the branching destination of the multi-story.
