Title: Data input device
Inventor: MURATA NAOYA
IPC: G06F3/02
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent junk data and illegal data due to mischief from being inputted by judging that data of specific bits at the head of inputted data are direct-input enabled data and then accepting following input data as effective one. SOLUTION: An input accepting process part 11 accepts an input signal from a keyboard 2 and discriminates what the input is. A head data array extraction part 12 extracts the data of the specific bits at the head from the accepted keyboard input. A data significance decision part 13 discriminates whether or not the following data are effective data according to whether or not the extracted data of the specific data matches previously set direct-input enabled data. When it is decided that the data are effective, an input data registering process part, 14 accepts the following input of the accepted keyboard input except the direct-input enabled data, as regular input data and stores the data in a file 15.

Title: Thin and uniform lighting device using a plurality of leds
Inventor: HINO TAKASHI
IPC: H01L33/60
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To efficiently generate a thin and uniform surface light emission by mounting an LED chip that can apply light in all directions on an upper surface onto a printed-wiring board, mixing powder with diffusion effect or reflection effect with resin, and performing resin molding to an entire LED chip-packaging surface. SOLUTION: Straight light being emitted on an entire surface from each point of an LED chip 1 is diffused and irregularly reflected in a mold due to powder with diffusion effect or reflection effect being mixed into a resin mold 4 for enabling the entire mold to emit light. Also, light emitted from an area other than a lighting surface is applied to the inside of the mold again by reflection machining on the inner surface of a packaging surface/case 5 of the LED chip 1 to compensate for the attenuation of the quantity of light from an end part. The LED chip 1 is directly mounted onto a printed wiring board 2 for achieving cooling effect, and further cooling machining is executed to the printed-wiring board 2 and the case 5, thus improving emission efficiency per power.
