Patent JP-S61125253-A (JP)
Title: Medium access control system
Inventor: SUZUKI HIDEO
Filed: 1984-11-20
Abstract: PURPOSE:To relieve the load of the CPU by defining a repeating status, token- holding status, and a token-sending status at each node and by performing the state transition by TPC-dedicated hardware independently without control by the CPU. CONSTITUTION:A token passing controller (TPC)10 is included in an adapter of each node, and inputs transmission data 600 in the repeating status. The controller 10 also stores the processing result from an MPU20 in an RAM40 after transferring the data by DMA (direct memory access) to a receiving buffer 50 without the controlling by the MPU20. Data to be transferred is transferred by DMA to the transmit/receiving buffer 50, and is made in transmission-ready status. If a token is transferred from other node, the TPC10 controls so that the repeating status transits to the token-holding status. And at the time when the transmitting of the transmit frame from the transmission buffer 50 is finished, the TPC10 controls so that the status transits to the token-transmitting status. And it finally sends the token, and further and again performs the control to transit to the repeating status by detecting the last byte of the frame.

Title: Solid-state image sensing device
Inventor: KOORIDO KUMIO
IPC: H04N5/369
Filed: 1988-09-30
Abstract: PURPOSE:To reduce the leakage amount of a light due to multiple reflection occurring between an optically shielding layer and a pixel electrode and to improve an optically shielding effect by presetting a reflection preventive film having smaller reflectivity than that of the shielding layer between the shielding layer and a transparent electrode. CONSTITUTION:A hydrogenated amorphous silicon photoconductive film 22 and an ITO transparent electrode 23 are deposited on a solid state image sensor chip. Further, a chromium oxide film as a reflection preventive film 24 and a chromium layer as an optically shielding layer 25 are deposited on the electrode 23 by a sputtering method. Then, a resist pattern 26 is formed in a desired pattern on the layer 25. With the pattern 26 as a mask the layer 26 and the film 24 are selectively etched, and the pattern 26 is removed. Even if an incident light is reflected on a pixel electrode 21 and advanced to the layer 25 side, the reflection at the layer 25 side is reduced due to the presence of the film 24. Thus, the leakage of a light due to multiple reflection between the layer 25 and the film 21 can be largely reduced.

IPC: H01L27/14
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To obtain a solid state image sensor in which the corner part contributes to enhancement of sensitivity by forming a concave lens for directing a light incident to the corner of a unit element toward each light receiving sensor part while diffusing directly above a part surrounded by adjacent light receiving sensor parts. SOLUTION: The upper layer part of an on-chip color filter (OCCF) 7 is cut off in concave shape and filled with a passivation material. A resin having refractive index smaller than that of a material forming the OCCF 7 is employed as the passivation material in order to refracts an incident light on the interface thereof, i.e., a concave surface 11a, toward the light receiving sensor part 3 side. The concave lens 11 is provided at the corner part 9a collecting part of unit pixels 9 where an on-chip lens 8 is not formed thus providing an effective region where the conventionally ineffective corner party 9a contributes to enhance the sensitivity by introducing the incident light to the corner parts 9a to the light receiving sensor part 3 of each unit pixel 9.

Title: Vertical polarizing circuit
Inventor: KAMIYA AKIYOSHI
IPC: H04N3/223
Filed: 1988-09-30
Abstract: PURPOSE:To unify the vertical amplitude of a picture and to improve the quality of the picture by adjusting the vertical amplitude of a saw-tooth-wave based on the change of a high voltage. CONSTITUTION:The terminal voltage of a modulating capacitor C4 of a diode modulator circuit 10 corresponds to the change of the high-voltage current, that is, the change of luminance and a horizontal deflection current corresponds to the change of luminance. When the terminal voltage of the modulating capacitor C4 is led into the connection of first and second resistors VR and R4 through a resistance R6, the luminance rises, the high-voltage current increases, the voltage of the connection rises and the current of a constant current circuit decreases. There, the amount of the discharge of a capacitor 3 reduces, the amplitude of a saw-tooth-wave voltage obtained by the capacitor 3 becomes smaller and it is prevented that the vertical amplfitude of the picture lengthens by the rise of the luminance. In the same way, when the brightness of the screen lowers and the high-voltage current decreases, the current of the constant current circuit increases, the amplitude of the saw-tooth-wave voltage is made larger and it is prevented that the vertical amplitude of the picture reduces.
