Title: Gallium nitride compound semiconductor light emitting element
Inventor: SENOO MASAYUKI
IPC: H01S5/323
Filed: 1994-02-08
Abstract: PURPOSE:To reduce the chip size of a gallium nitride compound semiconductor light emitting element and prevent short-circuits between its positive and negative electrodes so as to secure the light emitting efficiency of the element by removing a sapphire substrate on the side opposite to the side where gallium nitride compound semiconductor layers are laminated and forming one electrode on the semiconductor layer exposed on the removed part. CONSTITUTION:After successively forming an n-type layer 2 and p-type layer 3 on a sapphire substrate 1, a positive electrode 12 is formed on the entire surface of the layer 3. Then the half of the surface of the sapphire substrate where no gallium nitride compound semiconductor layer is laminated is cut off in a prescribed shape. After cutting, the substrate 1 is etched until the etched depth reaches the layer 2 and the layer 2 is exposed. After the layer 2 is exposed, negative electrodes 11 composed of Ti and Al are formed on the layer 2. Thereafter, a light emitting element is obtained by cutting the substrate into chips having a desired shape. Therefore, the electrodes do not come into contact with each other.

Abstract: PROBLEM TO BE SOLVED: To miniaturize a circuit board structure by providing a board incorporated component formed in the through hole of a board main body and conductive connection members which are formed on the surface of the board main body and conductively connect the board incorporated component and the other components. SOLUTION: The through hole 26a is formed in a copper-clad laminate 26. The resistor (board incorporated component) 28 as a circuit part where carbon is made into a paste form and is filled and formed is formed in the through hole 26a. Electrolytic copper plating 30 is executed on the copper foils 23 and 24 of the copper-clad laminate 26 and the upper and lower faces of the resistor 28, and electrolytic copper plating 33 is executed on them. The resistor 28 is conductively connected with the other circuit components through the copper foils 23 and 24, electroless copper plating 30 and electrolytic copper plating 33. Thus, the copper foils 23 and 24, electroless copper plating 30 and electrolytic copper plating 33 constitute the conductive connection member which conductively connects the resistor 28 with the other circuit components.  Thus, the circuit board structure can be miniaturized.

Title: Formation method of fluorescent screen of color picture tube
Inventor: OGURA RIYOUICHI
IPC: H01J9/227
Filed: 1978-02-14
Abstract: PURPOSE: To make the edge of a photosensitive part clear with its width fixed to a prescribed value, by covering the external surface of a panel with a photo absorptive material when exposing the photosensitive coating of the internal surface of the panel through a shadow mask.  
     CONSTITUTION: On the internal surface of panel 1, a photosensitive coating such as photosensitive fluorescent-material coating 2 is formed and the external surface of panel 1 is covered with photo absorptive material 6 which comes in excellent contact, can be detached and attached easily, and absorbs light excellently. When this is exposed, light passing through beam aperture 5 of mask 3 strikes coating 2 for exposure and light passing through coating 2 and reaching the external surface of mask 1 is absorbed by photo absorptive material 6. As a result, since the light will not strike coating 2 again after being reflected, bad influence of the reflection of the light passing specially through beam 5 slantingly is prevented, photosensitive part 2a of the coating after the exposure agrees accurately with part (a) to be exposed, and unevenness of the edge occurs. A fluorescent film obtained through development therefore forms correct dots or stripes too.

Abstract: PURPOSE:To correct the ununiformity of a recorded image by detecting a voltage impressed on a heating resistor and by changing the output voltage of a power source according to the detected voltage. CONSTITUTION:Pulse signals 51 and 52 generated by a clock signal which is generated in a clock generating circuit are supplied to common terminal switching elements Q1 and Q2 in a source driver to fluctuate thereby the number of the heating resistor 1 electrified in accordance with a image signal 41 supplied to a sync driver 4 and further to fluctuate voltage appearing the output ends 31 and 32 of the elements Q1 and Q2. This voltage is sampled to a control part 24 by a sampling clock 53 and the control part 24 supplies a high-frequency inverter 22 with a control signal 25 having the voltage variation inversely proportional to the afore-said voltage. Meanwhile, the primary-side rectifying- smoothing part 21 of a power source part 2 converts AC voltage of 100V to DC voltage, and the inverter 22, converting this to a prescribed high frequency, changes a crest value in accordance with the voltage level of the signal 25, increases the output voltage of the secondary-side rectifying-smoothing part 23 with the decrease of the voltage generated at the output ends 31 and 32, and thus compensates the fall of a heat value of the heating resistor 1.

Abstract: PURPOSE:To obtain the inexpensive compact driving circuit wherein small capacity element can be used, by controlling the conduction of the brushless motor by an AND value of a signel outputted from a level detector and a detected position signal when a power source voltage is higher than a specified voltage. CONSTITUTION:When the output voltage of a control power source circuit 6, which rectifies the power source of a solar battery 1, is increased to a value higher than VH, the signal is outputted from the level detecting circuit 7. IN an AND circuit 8, said signal and the output of a position detector 2 are operated. Based on the result, a driving element 4 for a stator coil 5 is turned ON through an amplifier 3. Based on said ON state, however, the output voltage of the solar battery 1 is quickly decreased, and the output voltage of the control power source circuit 6 becomes lower than VL (set at a value higher than the lowest operating voltage of the position detector 2) after a specified time T0. Then the driving element 4 is turned OFF, the output voltage of the solar battery is quickly increased, and the voltage of the control power source circuit 6 becomes higher than VH after a specified time T1. Said operation is repeated and the rotation is started.
