Title: Liquid crystal display element
Inventor: ITO YOSHITAKA
IPC: G02F1/1335
Filed: 1989-05-18
Abstract: PURPOSE:To obtain the bright liquid crystal display element which has a lens array with high light convergence performance even when a light source which is inferior in the parallelism of projection luminous flux is used by embedding microlenses with a high numerical aperture in a counter substrate. CONSTITUTION:Lens bodies 102 are embedded in the counter substrate 101 and a transparent layer and an orienting layer 109 for holding liquid crystal are formed on the surface. Then the respective lenses in a plane lens array are so arranged having their optical axes correspond to respective display elements of a liquid crystal display element one to one. Namely, light which is incident on the counter substrate is converged by the microlenses 102 and transmitted through display picture element opening parts 104 corresponding to the microlenses one to one without being cut off by a light shield film 103. Thus, the quantity of the transmitted light is controlled to maintain a high contrast ratio, thereby obtaining the bright liquid crystal display element.

Title: Controlling method for combustion of boiler
Inventor: HINO ISAO
IPC: F22B35/00
Filed: 1989-05-17
Abstract: PURPOSE:To supply steam in either case a flame failure occurs during the transition period of shifting from low rate combustion to high rate combustion or during high rate combustion, by a method wherein a boiler is re-started and combustion is forcibly continued at a low combustion rate. CONSTITUTION:When a flame failure occurs during combustion, it is judged by a judging circuit 17 that it occurs during transition period of shifting from low rate combustion to high rate combustion or during high rate combustion. When it is judged so, a boiler is automatically re-started, and combustion is continued at a low combustion rate. Even when a signal from a pressure detector 13 is of a high rate combustion, low rate combustion is continued so as not to stop supplying steam since a flame failure may occur again when combustion is shifted to high rate combustion. On the other hand, if it is a flame failure that occurs during ignition or low rate combustion, a flame failure interlock is put in action to stop operation of the boiler. In case a flame failure occurs during transient period of shifting from low rate combustion to high rate combustion or during high rate combustion, the boiler is re-started to continue operation, however, data on the fact that flame failure occurs is stored, and a flame failure alarm is submitted. The boiler is stopped to check and repair defaults by arranging a suitable time period to shut the boiler down.

Title: Sound correction device
Inventor: IIJIMA TAKAYUKI
IPC: G10L19/00
Filed: 1985-06-10
Abstract: PURPOSE:To prevent the generation of noise even when a sound data is in error consecutively by applying fade-out from the front part of the sound data causing an error, making an erroneous data silent and applying fade-in. CONSTITUTION:A sound data 11 is inputted at first in a memory 1, delayed by Tsec and becomes a data 12, and the result is fed to a signal processor 2. An error signal 14 representing an error of the sound data is inputted also to the signal processor 2 and when an error signal comes, the signal processor 2 starts fade-out to the sound data 12 and outputs the resulting data 13. The time for fade-out is Tsec the same as the delay time of the memory 1 and The data having an error actually is inputted to the signal processor 2 after the error signal 14 comes after Tsec because the signal is delayed by the memory 1. Thus, the erroneous data part is made silent. When an error is generated continuously in the data, the silent period is extended by the period corresponding to it and then fade-in is started.

Filed: 1989-05-19
Abstract: PURPOSE:To obtain a method for rationalized judgement of the quantity of paste mounted on electrolytic capacitors by judging the quantity of the paste mounted on the capacitor elements with a current passed between measuring terminals through a capacitor element. CONSTITUTION:When voltage is applied through measuring terminals 12 and 14 in contact with the end faces 6a and 6b of a paste-poured capacitor element 2, a current Ic is passed between the measuring terminals 12 and 14 through the capacitor element 2.
