Abstract: PURPOSE:To obtain an optical conversion display element which does not require an external power source, by providing a photocatalyst layer on a substrate and using two kinds of compound which are oxidized or reduced by the photoexitation of the photocatalyst and fixing a coloring compound to form a cell. CONSTITUTION:A photocatalyst layer 12 where a semiconductor 1 such as SrTiO2 is allowed to be carried on Pt is provided on a substrate 11 such as a ''Teflon '' film of a porous structure having minutes holes. A light-transmittable substrate 13 is provided to face to the photocatalyst layer 12, and a coloring compound 3 which is excited optically by a gaseous N2 laser 2 and is oxidized or reduced and a solution 15 which a compound 4 dissolves in are charged between substrates 11 and 13, thereby obtaining an optical conversion display element. The photocatalyst layer 12 is treated with a dilute hydrochloric acid to fix methyl pyogens 3 which are colored by reduction. Ascorbic acid 4 which is achromatic even when it is oxidized is dissolved in water to obtain the solution 15. When this element is excited optically by the laser 2, coloring matters 3 are colored in blue by reduction; and thus, the optical conversion element where photocell elements are displayed in blue and an external power source is not required but only the optical energy is used is obtained.

IPC: H04N19/85
Filed: 1986-07-21
Abstract: PURPOSE:To prevent the deterioration of the quality of a picture or voice by coding information to be transmitted, adding a parity bit then transmitting, converting a reception data to a parallel data to generate a predictive value, and using thus produced predictive value when an error exists in the data. CONSTITUTION:An analog image signal inputted to a transmission side A is PCM coded by an A/D converter 1, in the means time, a parity bit generation circuit 2 generates a parity bit. A P/S converter 3 converters thus produced parallel signals to serial digital signals and outputs them to a transmission line 4. On the reception side, the signals are converted to parallel signals by a S/P converter 5, and these signals are outputted to a switch means 8, a predictor 7, and to a parity check circuit 6. The circuit 6 checks the data its and the parity bits, and, if the reception signals do not include an error, connects the input of a D/A converter 9 directly to the output of a D/A converter 9. When an error is detected, the input of the converter 9 is connected to the output of the predictor 7, hence the deterioration of the quality of a produced image is reduced.

Title: Preparation of semiconductor device
Inventor: KOGURE NAOSHI
IPC: H01L23/02
Filed: 1981-10-28
Abstract: PURPOSE:To prevent short-circuit within a device due to splashing of brazing material by applying a pressure to a brazing material placed between a vessel and cover and by sealing them under a temperature below the melting point of brazing material under the atmospheric condition. CONSTITUTION:A brazing material 5 is applied between a metallized layer 3 of vessel 1 and a metallized layer 4 of a cover 2 and a pressure P1 is applied across the vessel 1 and the cover 2. The ambient temperature is set to the melting point T2 of the brazing material under the pressure P1 while the melting point of brazing material 5 is T1 or less under the atmospheric condition. At the upper and lower surfaces, the brazing material 5 receives a pressure of P1, but both side surfaces receive an atmospheric pressure P0. Therefore, the melting point of brazing material drops to T1 at the upper and lower surfaces or remains at T0 at the side surfaces. Since the ambient temperature is kept at T1, only the upper and lower surfaces of brazing material 5 fuse and combine with the layers 3 and 4, resulting in hermetical sealing. Moreover, since both sides are not fusing, drops of brazing material do not splash.

Abstract: PURPOSE:To enable desired quantity of emitted light to be maintained stably concerning to time by providing a photoreceptor in proximity to a lamp and a control circuit and performing dimming controlling. CONSTITUTION:A detector S is a photoreceptor such as photodiode or the like provided in proximity to a lamp L. The signal corresponding to the quantity of emitted light of the lamp L is fed back to a control circuit C1. A manual controller for presetting the quantity of light emitted by the lamp L as desired is incorporated into the circuit C1 or C2 through a variable resistor, etc. The control circuit C1 controls the effective voltage to a stabilizer RG approximately at rated voltage or more than said voltage the detector S is detecting the predetermined quantity of light or under or when said quantity is extremely low, thereby providing the lamp conduction of, for example, predetermined repetitive switching width. Near the predetermined quantity of light, the effective voltage is lowered to provide the current conduction of decreased width without changing, for example, switching periods. The effective voltage is lowered when the predetermined quantity of light is exceeded. With such constitution, the lighting is continued at the stabilized quantity of light, and the exposure controlling stable with time is accomplished.
