Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To obtain uniform surface brightness without generating wrinkles, etc., in a reflecting part which reflects incident light on a light guide plate in the direction of a liquid crystal panel by forming a metallic reflection film on the light guide plate made of a transparent acrylic plate lighted by a cold cathode ray tube (EL). SOLUTION: A light guide plate 13 made of a transparent acrylic plate uses light as surface light source supplied from a FL tube 2. A reflection film 14 reflects light going downward in the direction of a liquid crystal panel 1. The light emitted by the FL tube 2 is made incident on the light guide plate 13 and spread over the whole light guide plate 13, to become a surface light source. The light going downward is reflected by the reflection film 14 and goes in the direction of the liquid crystal panel 1. The light is further diffused by a diffusion sheet 5 to reduce unevenness of brightness, and is converged by a prism sheet 6 to illuminate the liquid crystal panel 1.  The reflection film 14 is formed by complete and close contact of a metallic film such as aluminum, etc., vacuum-deposited on one of the surfaces of the light guide plate 13, therefore, irregularity is not generated in the reflected light but the light becomes an even surface light source.

Title: Solder bump mounting method
Inventor: SAKATSU TSUTOMU
IPC: H05K3/34
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a cooling method for reflow process by which residual stresses are made to about zero near the center of temperature change in a temperature cycle. SOLUTION: In a solder bump mounting method, a bump 3 is solidified after either a semiconductor 1 or a substrate 2 having the smaller coefficient of thermal expansion is cooled while expansion of the temperature of the substrate 2 or semiconductor 1 having the higher coefficient of thermal expansion is suppressed by lowering its temperature to a certain degree before the bump 3 solidifies, because a stress occurs in an ordinary reflow process when the semiconductor 1 and substrate 2 have different coefficients of thermal expansion. When the bump 3 is solidified in such a way, the stress applied to the bump 3 when the temperature of the bump 3 drops to a room temperature level become smaller. When the semiconductor 1 is connected to the substrate through the ordinary reflow process in the temperature cycle shown in Fig.  (A), a stress is always applied to the bump 3 after the bump 3 is cooled as shown in Fig. (B) due to the difference in thermal expansion between the substrate 2 and the semiconductor 1 and the maximum stress also become larger, but, when the bump 3 is cooled in the above-mentioned manner, the stress becomes about zero near the center (Tic) of the temperature change as shown in Fig. (C).

Title: Analog/digital converter
Inventor: NODA TSUTOMU
IPC: H03M1/10
Filed: 1983-04-15
Abstract: PURPOSE:To attain an automatic correction of the DC offset by subtracting the digital value stored in a memory from the A/D converted digital signal. CONSTITUTION:Switches 11 and 12 are closed in a queuing state of A/D conversion by the control signal supplied from a control circuit 20. Then the DC offset is converted into a digital signal by an A/D converter 6 via sampling/holding circuits 3 and 4 and then a changeover switch 5 and then stored to memories 15 and 16 in the form of a DC offset correction amount via changeover switches 13 and 14. In an A/D conversion mode, the A/D converted output is supplied to a digital subtractor circuit 17. At the same time, the data stored in the memories 15 and 16 are also supplied to the circuit 17. Thus the DC offset correction amount undergoes a subtraction. As a result, the data on the DC offset error can be automatically collected in an A/D conversion mode. Thus the DC offset is automatically corrected to obtain an accurate digital signal.

Title: Digital data reception circuit
Inventor: TOKUNAGA KENJI
IPC: H04L25/08
Filed: 1982-04-20
Abstract: PURPOSE:To decrease the generation of enoneous decision of data due to the distortion given on the reception data from external noises, by generating a sampling pulse of plural number of times in one bit of the reception data, integrating the result of sampling, and deciding the content of each bit of the reception data with the integration value, in a reception circuit of an interface device. CONSTITUTION:An AND circuit 3 ANDs data sections a1-a8 of a reception signal 8 and a pulse signal (d) and gives the result to a counter 7 as a signal (e). In taking logical product between the reception data of the 1st bit a1 and the signal (d), the 10th- the 12nd pulses of the signal (d) are gated with the AND circuit 3 at the fall-in of the level of a distortion n1 and are not obtained as the signal (e). Thus, the counter 7 counts the number of pulses of the signal (d) while the signal a1 is in a high level, and counts up to 13 in this sampling. A decoder 8 decodes a 4-bit binary code from the counter 7 and when the value reaches >=8, an output (f) is made active. Thus, the bit a1 is discriminated to be ''1'' for the content at the decoder 8 when the number of pulses reaches eight.
