Title: Resin film and method for connecting electronic parts by using resin film
Inventor: FUNADA YOSHITSUGU
IPC: H01L23/28
Filed: 1999-02-26
Granted: 2001-05-16
Abstract: This invention provides a resin film preferably used for mounting a semiconductor chip on a substrate through flip-chip connection, and a method based on the use of such a resin film. The resin film has a laminated B/A/B structure where a first resin layer (A) having inorganic particles dispersed in an insulating resin is sandwiched by second and third resin layers (B) having no inorganic particles in their insulating resins. The method for connecting electronic parts comprises the steps of forming metal projections (bumps) on a plurality of connection terminals prepared on the surface of a first electronic part; preliminarily pressing the resin film against a plurality of connection terminal surfaces of the other electronic part; applying pressure onto the connection parts in the presence of heat after having properly aligned the metal projections of the first electronic part with the corresponding connection terminals of the other electronic part, thereby establishing electric connection and at the same time mechanical contact between the two electronic parts through the resin film melt and solidifying of resin film.

Granted: 2000-03-21
Abstract: An optical disc system including a focusing mechanism and a tracking mechanism, in which the mechanism are controlled by feedback loops having electronic circuits for generating a servo error signals. The error signal are communicated in the feedback loop for affecting corrections of the focusing mechanism and the tracking mechanism. The optical disc system is provided with digital lead/lag compensation circuit assembly including a servo loop having servo loop transfer function and an error signal. The circuit assembly includes a motor or actuator having a mechanical resonance frequency being less than a predetermined sampling frequency and a compensation circuit for stabilizing the servo loop. The error signal of the servo loop is sampled at the predetermined sampling frequency. Normalization of the error signals to the information signal occurs during sampling. The compensation circuit has a compensation transfer function including a single lead and a complex lag for producing a notch filter with a notch. The compensation transfer function is formulated so that the notch occurs at approximately one half the predetermined sampling frequency thereby reducing amplitude of the mechanical resonance frequency in the servo loop transfer function. The optical disc system also includes a mechanical isolator for vibration isolation and accommodation of thermal expansion, an oscillator with a resonant circuit having an increased resistance, an improved focus capture system, and an identifying blank sectors device in a storage medium.

Title: Method for forming transparent conductive film using chemically amplified resist
Inventor: TSUJIMURA TAKATOSHI
IPC: H05K3/06
Filed: 1999-10-20
Granted: 2002-01-21
Abstract: To provide a process for patterning an ITO film, which is capable of preventing, for patterning an indium-tin-oxide (ITO) film by using a chemically amplified resist, resist peeling or reduced adhesion even if the ITO film is exposed to a white light after resist development. An amorphous ITO film is first formed on a substrate, and a negative chemically amplified resist is directly provided on the film, exposed and developed. In a resultant structure having a resist pattern on the amorphous ITO film, even if exposed to a white light, no resist peeling or no reduced adhesion occurs, and thus satisfactory visual inspection can be performed without adversely affecting subsequent steps. For the structure determined as a good product by visual inspection, the amorphous ITO film is etched through the resist pattern used as a mask, the resist pattern is removed, and then by heating the amorphous ITO film at the ITO crystallization temperature or higher, the crystallized ITO pattern having chemical resistance and good electrical conductivity can be obtained.

Title: Method and device for measuring convergence of CRT and video signal generator applied to the method
Inventor: NISHIKAWA NOBUHIRO
IPC: H04N17/04
Filed: 2000-03-01
Granted: 2003-07-21
Abstract: To attain quick and highly accurate measurement by reducing repeated measuring errors in highly accurate CRT convergence measurement. The CRT convergence measurement is to input the smoothed signal SP' to a color CRT 6 after smoothing a video signal SP (signal in which the irradiation section of electronic beams is expressed by a rectangular wave) consisting of a rectangular wave outputted from a signal generator 4 through a filter circuit 41. The CRT 6 displays a prescribed test pattern on the basis of the smoothed video signal SP', and a control part 36 in an image processor 3 calculates the quantity of convergence. Since the irradiation of electronic beams is controlled by the signal SP' obtained by smoothing the rectangular wave, the rise/fall part of electronic energy distribution to be radiated to a fluorescent surface is eased and a change in the center of gravity of luminance due to a change in the positions of electronic energy distribution corresponding to the array of phosphors is reduced, so that errors in repeated measurement can be reduced.

Granted: 2001-10-01
Abstract: An IEEE 1394 compliant bus controller (11) transfers data packets between connected nodes (1, 2, 3, 4, 23). The controller includes a processor (13, 14) which divides a series of data into blocks and then stores the blocks in multiple packets (one block per packet). The packets are then transferred over the bus from a source node to a destination node at equal intervals until the entire series of data has been transferred. An initialization prohibition unit (15, 17, 18, 19, 20, 22) prohibits initialization of the nodes during the data transfer which may be caused, for example, by hot plugging (connecting a new node to the bus) during the data transfer.

Abstract: A method and apparatus for stacking curved, triangular snack food chips, e.g., tortilla chips, for packaging in a sleeve-type container. The chips are fed into a first, U-shaped vibratory chute, which automatically causes the apex corners of the chips to extend beyond the opposing base edges of adjacent chips and which automatically orients the chips such that lines about which they are curved are oriented parallel to the longitudinal direction of the U-shaped chute. The chips are then fed into a W-shaped chute, with the chips facing in opposite directions falling automatically into opposite troughs of the W-shaped chute. The chips are then automatically reoriented by 120 DEG such that their upturned apex corners point in the direction of travel, and the chips are stacked automatically as they slide up along one another in a shingled manner.
