Title: Imaging apparatus
Inventor: MISAIZU TORU
IPC: H04N1/29
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To correct variation of gray scale due to aging even in an imaging apparatus where high resolution binary data is rendered to multivalued data through resolution conversion. SOLUTION: A decomposer 21 command interprets a PDL and writes into binary data at a resolution higher than an engine resolution. A rendering section 23 converts the binary data into an engine resolution and renders it into multivalued data by doubling. When the gray scale of a test pattern exceeds predetermined conditions, a gray scale control section 25 performs gray scale correction for a test pattern from a pattern generator 24 until a desired gray scale is attained and holds the correction amount. In a normal output operation mode, the gray scale control section 25 corrects the gray scale of each pixel of the multivalued data with that correction amount.

Title: Mos transistor and manufacture thereof
Inventor: FUJII EIJI
IPC: H01L21/28
Filed: 1989-11-08
Abstract: PURPOSE:To enable the area of a MOS transistor cell to be reduced by forming a polycrystal film of the same conductive type as a source.drain region on at least one part of the source.drain region. CONSTITUTION:A polycrystal silicon film 13 is formed on a source.drain region 19. In this case, the source.drain region 19 practically becomes large, thus minimizing the positional allowance between a CVD tungsten 16 and the source.drain region 19. Thus, the cell size of a transistor can easily be reduced. Further, the CVD tungsten 16 can directly be connected to the source.drain region 19 through the polycrystal silicon 13 so that increase in the contact resistance for the reduction in area of the contact region can be restricted.

Title: Data and clock restoration circuit
Inventor: SAI SOUKUN
IPC: H04J3/06
Filed: 1994-11-25
Abstract: PURPOSE: To supply a stabilized cock even when the input of a data signal or power supply is not normal. CONSTITUTION: When power is normally supplied and data signal is normally inputted, a loop selection switch 30 outputs a state '1' and a 1st loop circuit is selected. At this time, the phase of the data signal is compared with a clock outputted from a voltage controlled oscillator(VCO) 4 and a synchronizing clock is generated. In the case of restoring the system after a short-circuiting of a transmission line, the transmission interruption of a data signal or the interruption of power supply, a data signal monitoring part 40 or a power supply monitoring part 50 outputs a state '1', so that the switch 30 selects a 2nd loop. Then the phase of a reference clock built in the system itself is compared with that of a clock outputted from a VCO 28 to generate a synchronizing clock.

IPC: H01C17/242
Filed: 1990-10-29
Abstract: PURPOSE:To eliminate the part wherein the resistance value is abruptly increased for avoiding the disconnection by equalizing the intervals between trimming slots with the width of resistant film. CONSTITUTION:Two each of shape trimming slots 16a, 16b are cut in the long direction at both ends of a resistant film 14. Next, the first resistance value trimming slot 17a 0.5mm long is cut from the end of the resistant film 14 not to be intersected with the other shape trimming slot 16b. Likewise, the second resistance value trimming slot 17b 0.5mm long is cut from the end of the resistant film 14 on the shape trimming slot 16b side not to be intersected with the shape trimming slot 16a. Through these procedures, the interval A1 of 0.1mm between the resistance value trimming slots is equalized with the residual widths B1, B2. In such a constitution, such defects as the insufficient residual width of the resistant film 14 as well as the insufficient intervals between the terminal ends of the trimming slots and both ends of the resistant film 14 can be avoided thereby enabling the part wherein the resistant value is abruptly increased to be eliminated.
