Title: Image display device
Inventor: TSURUMATSU TAKAYUKI
IPC: G09G3/20
Filed: 1990-07-25
Abstract: PURPOSE:To form the inconspicuous joints between plural band blocks by dividing a display screen to the plural band blocks in a horizontal direction and separately providing projection driving circuits for driving picture elements in the respective blocks. CONSTITUTION:The projection driving circuits 13 for driving the picture elements which can driven even the picture elements of the adjacent blocks are provided near the boundaries. Inputted image signals are subjected to time base expansion and are inputted in parallel to the respective projection driving circuits. The continuity of the images between the picture elements of white dots 21 and black dots 22 at the boundaries of the respective band blocks is lost and the joints are appear in relief when the characteristics of the respective driving circuits 13 vary and the driving signals are irregular. The projection driving circuits 13 for driving the picture elements near the boundaries are, thereupon, changed over for each of the respective lines in a perpendicular direction. Differential component decrease if the driving signals spacially disperse the different picture elements and, therefore, the joints thereof are inconspicuous.

Title: Lens supporting mechanism and shake correcting camera
Inventor: KAI TADAO
IPC: G03B5/00
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To make a lens movable in a plane perpendicular to an optical axis, with a simple constitution by providing a supporting member for movably supporting a lens holding part and a regulating part for regulating the motion of the supporting member. SOLUTION: When force in a direction perpendicular to the optical axis is exerted on a shift lens holding member 2, from the outside, to move the member 2, a beam-like member 4 is inclined toward the holding member 2. Consequently, a curved surface part 4b is inclined so as to roll on a reference surface 3a. At this time, the center of the radius of curvature of the curved surface part 4b is a joining part 4a, so that the distance between the holding member 2 and a base plate 3 is always kept the radius of curvature R, not to be changed. In other words, even if the shift lens 1 is driven to shift, the lens 1 is never displaced in an optical axial direction. Thus, a lens supporting mechanism not for displacing the shift lens 1 in the optical axial direction, at the time of shift-driving the lens 1 can be obtained with the simple constitution consisting of a small number of parts.

Title: Ceramic multilayered board for flip chip and its manufacture
Inventor: KOSAKATA AKIYOSHI
IPC: H05K1/11
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To ensure sufficient bonding reliability when a viahole conductor exposed on a board surface is used as a pad, as it is. SOLUTION: A via hole 24 for pad of an alumina green sheet 23 is filled with high melting point metal paste such as molybdenum and tungsten. High melting point metal paste whose baking shrinkage factor is smaller than that of the alumina green sheet 23 is used, and adjustment of the baking shrinkage factor is performed by adjusting particle diameter of metal powder. After the alumina green sheet 23 is laminated on a ceramic green sheet of the other layer and baked, plating treatment is performed on the surface of a via hole conductor 26 exposed on a board surface, and a pad 22 is formed. In this case, since baking shrinkage factor of the via hole conductor 26 is smaller than that of the alumina green sheet 23, an upper end portion (a pad 22) of the viahole conductor 26 makes a protruding shape which is swelled from the board surface by baking.

IPC: H04J3/00
Filed: 1992-07-24
Abstract: PURPOSE:To simplify the processing of a time division multi-plexing part in a time division multiplex communication equipment. CONSTITUTION:The sound signal from a transmitter 11 is encoded in an encoder/decoder 13 by 8kHz sampling frequency to become digital sound data having the 4-bit width and the data are converted to serial data and is successively written in the buffer memory of a serial interface 14. The serial interface 14 counts the read clock and the write clock supplied to the buffer memory and when the difference between the write address and the read address is a time corresponding to >= one time slot (5ms), the serial interface 14 requests the data read to the time division multiplexing part. A TDMA control part 16 continuously reads out the one-time slot portion of sound data by 384kbps equal to the transmission rate and adds required header information to the data and outputs it to a modulator 17. That is, the data are read out to the time division multiplexing part at every 5ms.
