Title: Compound semiconductor switching circuit device
Inventor: ASANO TETSUO
IPC: H01L21/822
Filed: 2004-12-22
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that, in a switching MMIC, it is sometimes the case that the control resistance is arranged close to a common input terminal pad and an output terminal pad to improve the breakdown voltage and protection elements are connected using a dopant region in the periphery of each pad, however, a high-frequency signal path occurs due to the parasitic capacitance of the control resistance having a low resistance value and the protection elements, which causes deterioration in isolation.  <P>SOLUTION: A high resistor is connected between a switching element and the protection element closest to the switching element and to the control resistance between adjacent protection elements. Due to this structure, the high-frequency signal path is cut off, and hence the leakage of high-frequency signals can be prevented even if the parasitic capacitance is generated by connecting the protection elements. Consequently, the breakdown voltage is improved and thereby the deterioration in isolation can be suppressed.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Filed: 2004-12-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a heat transfer printer which reduces an impact when the end section of a printing medium rushes into a space between carrying rollers and gets out from the space between the carrying rollers, i.e., a speed variation when a frameless printing for which there is no margin on the front and rear sides in the carrying direction of a printing medium is performed, and prevents the printing grade form deteriorating without using a complicated mechanism for reducing stripes on the printing surface, and without sharply increasing costs.  <P>SOLUTION: An elastic body such as a rubber is used for sections other than a gripping section such as a protuberance on the roller surface which carries the printing medium 2 from among the carrying rollers 14, 15, 16 and 17. Thus, the impact when the end section of the printing medium 2 rushes into a space between the carrying rollers and gets out from the space between the carrying rollers is softened, and the printing grade is prevented from deteriorating.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide an on-vehicle camera system capable of shortening delay time until display and the time deviations of respective camera video images and appropriately displaying conditions around a vehicle to a driver.  <P>SOLUTION: In the on-vehicle camera system for video display, the video signals of video images photographed by a plurality of cameras are inputted as interlace signals and successively stored in an input buffer by a field unit. When field video signals from the plurality of cameras are arranged (the time t3), latest field video signals (Even1b and Odd2a) in the video signals from the respective cameras are used, address conversion of respective video data is performed, and output video signals (DataOa) are generated. Thus, the deviation of the video images between the cameras (a difference between the time t2 and the time t5) is suppressed to be 1 field (16.7ms in the case of NTSC) at maximum. Also, the maximum delay time until output becomes a 3-field period (about 50ms at maximum) as the total (t4-t5) of the respective required time of an input deviation (t2-t5), input (t3-t2) and the address conversion (t4-t3).  <P>COPYRIGHT: (C)2006,JPO&NCIPI
