Title: Optical space transmission equipment
Inventor: KURATA NOBORU
IPC: H04B10/114
Filed: 1989-04-28
Abstract: PURPOSE:To ensure the space transmission for an optical signal even when an obstacle stands in the way by sensing the obstacle, varying the radiation direction of an optical signal from a light emitting element and radiating the optical signal in a direction in which no obstacle exists. CONSTITUTION:Plural 1st and 2nd light emitting elements 12, 13 driven by an electric signal such as an audio signal radiate an optical signal 22, and part of the optical signal 22 is made directly incident in an optical receiver 19 in the normal state to establish the transmission system. For example, when an obstacle 20 such as a person crosses the optical path and interrupts the optical signal 22, a reflected light 23 by the obstacle 20 is detected by a photodetector 14, the control section 16 drives an electromagnet 17 to move the plural 2nd light emitting elements 13 in the direction of the arrow 21a. An optical signal 24 radiating from the 2nd light emitting element 13 is reflected on, e.g. an indoor wall face 18, the reflected light 25 reaches the rear side of the obstacle 20, made incident in the optical receiver 19 to ensure the signal transmission system. Thus, the signal transmission is ensured even at tentative interruption of the optical path.

IPC: C23C16/40
Filed: 1979-08-27
Abstract: PURPOSE:To prevent the cracks that would be caused by the difference in the thermal expansion coefficients, by covering the top and the bottom of an Si3N4 film by a relatively soft insulating film such as an Si oxide film containing phosphorus, an Si oxide film containing excessive Si, or the like. CONSTITUTION:The first wiring layer 3 is provided on an SiO2 film 2 on an Si substrate 1; an SiO2 film 4 containing phosphorus, an Si3N4 film 5, an SiO2 film 6 are layered thereon; thereby an interlayer insulating film 7 is formed.

Title: Recorder provided with vddp control function
Inventor: GOTO TOMOYUKI
IPC: G03G15/02
Filed: 1988-05-02
Abstract: PURPOSE:To maintain a high picture quality even when the fatigue of a photosensitive body, etc., occurs by compensating a decline in charging potential caused by the fatigue of the photosensitive body and contamination, deterioration, etc., of a charge corotron whenever the power supply is turned off and turned on. CONSTITUTION:An electrifying means 06 which electrostatically charges a photosensitive body, surface potential detecting means 01 which detects the charged potential of the photosensitive body, and arithmetic process controlling means 04 which controls the dark potential of the photosensitive body by controlling the means 06 upon inputting the surface potential detected by the means 01 are provided. Then a set-up cycle is executed at the first power supply turning-on time and VDDP (dark development potential) is automatically matched to an aimed value. During copying operations, the VDDP is maintained at the aimed value by sampling the inter-image VDDP patch area holding the VDDP at every cycle. Since the decline in the charged potential of the photosensitive body caused by the fatigue of the photosensitive body and contamination, deterioration, etc., of the charge corotron is compensated at every turning off and turning on of the power supply, a high picture quality can be maintained even when the fatigue of the photosensitive body, etc., occurs.
