Title: Timing reproducing system
Inventor: FUKUDA SETSU
IPC: H04L7/033
Filed: 1988-01-20
Abstract: PURPOSE:To reduce phase errors by fetching a receiving signal to be waveform- shaped by means of the timing clock of a digital PLL, estimating an impulse response from fetched data, and controlling the phase of the timing clock of the digital PLL. CONSTITUTION:A line equalizing means 1 corrects the receiving signal deteriorated by the characteristic of a transmission line and shapes a waveform. An arithmetic control means 3 fetches the waveform-shaped receiving signal by the timing clock, a peak value in the impulse response and an impulse response value before 1 time slot are estimated from the fetched data, and the values are compared with the values after a fixed period. By such a comparison, a reproducing clock is advanced when the reproducing clock of a digital PLL 2 is lagged, and the former is lagged when the latter is advanced. Thus, by the comparison in the arithmetic control means 3 and the control, the reproducing clock with a few phase errors can be obtained.

Title: Semiconductor device
Inventor: HATSUTORI TSUKASA
IPC: H01L21/60
Filed: 1981-01-23
Abstract: PURPOSE:To reduce the cost of a semiconductor device and to increase the reliability of the device by employing for a thermal press bonding material a silver wire sulfided on the surface and covered with silver sulfide, thereby reducing the disconnection trouble ratio as compared with that of a gold wire and preventing the migration. CONSTITUTION:An Ag wire is used as a bonding material instead of the conventional Au wire. The Ag wire is exposed, for example, with hydrogen sulfide atmosphere to form a silver sulfide film on the surface, and when a ball is formed by a hydrogen torch at the bonding time, the sulfide of the ball is reduced, and is thermally pressed. Or, after the bonding, the ball is exposed with  hydrogen sulfide atmosphere to form a sulfide on the surface. In this manner,  the disconnection trouble ratio in the recrystallization boundary of the ball can  be reduced as compared with the case of using the Au material, and an Ag  migration can be prevented due to the covering of the sulfided silver, thereby  reducing the short circuit trouble ratio. Further, the cost of the material can  also be reduced.

Filed: 1982-01-25
Abstract: PURPOSE:To obtain a funnel for a cathode-ray tube, in which the area over which a getter is diffused can be increased, by making the inner wall of the funnel a wavy or curved surface. CONSTITUTION:The inner wall of a funnel 2 is formed into a wavy or curved surface. As a result, since the inner wall of the funnel 2 is irregular, the surface area of a getter film 5 becomes two to three times that of the conventional one, and the getter effect becomes excellent. Thus, since the surface area of the getter film 5 can be extended, the life and the reliability of a color picture tube are increased. The color picture tube consists of a panel 1, a funnel 2, an electron gun 4 containing a getter 3, and the other members contained in the electron gun 4. The getter 3 appended to the electron gun 4, after the exhaustion process is completed, is scattered by high-frequency heating so as to form the getter film 5 on the inner wall and the like of the funnel 2, and serves for both absorption of gas contained in the tube and increase of the vacuum degree in the tube.

Filed: 1979-01-29
Abstract: PURPOSE:To make it possible to realize high selectivity by fixing an interval of split electrodes so that attenuation characteristics will be symmetric between the right and left. CONSTITUTION:While inside electrode 2 is provided near the center of one side of piezoelectric rectangular ceramic plate 1, outside electrode 3 is arranged at its circumference, and entire-surface electrode 4 is provided on the other side; and an input is applied between electrodes 2 and 4 and an output is led out between electrodes 3 and 4. This piezoelectric filter has attenuation characteristics asymmetric between high and low-frequency ranges on the passing band under an influence of input-output electrode capacity Cs, and capacity Cs should be reduced to make attenuation characteristics symmetrical between the right and left. For the purpose, when an interval between electrodes 2 and 3 is denoted by G and the thickness of ceramic plate 1 is represented by T, a value of G/T exerts an influence upon capacity Cs to fix this value preferably not less than 1.2. Consequently, right-left symmetry of attenuation characteristics can be obtained and high selectivity can also be realized.
