Title: Charge coupled semiconductor device having dynamic control
Inventor: AANORUDOUSU YOHANESU YURIANA B
IPC: H01L27/14
Filed: 1985-04-23
Abstract: In a CCD, especially in an image sensor device, the information density can be doubled in that the electrodes (21, 22, 31, 32...) are switched separately between a clock signal and a reference signal. Clock signals and reference signals are obtained as output signals of a shift register (13) controlled by a multi-phase clock, which is realized, for example, in C-MOS technology. Information at the input terminal (107) of the first stage (101) of the shift register (13) determines, after having been passed on or not having been passed on depending upon the clock pulse signals of the register clock, the output signal of the next stages (101) of the shift register (13) and hence the voltage variation at the electrodes (21, 22, 31, 32...) connected to the outputs (113) of the stages (101).

Title: Color image processor
Inventor: NISHIMURA KAZUYUKI
IPC: H04N1/46
Filed: 1997-03-20
Abstract: PROBLEM TO BE SOLVED: To provide a color image processor with which plural patterns for color correction at the different levels of lightness can be prepared by performing gamma correction to pattern data for color correction which is composed of the image patterns of different hues concerning certain lightness, based on plural gamma transformation curves. SOLUTION: Assuming that a color correction data storage part 1 holds hue data only concerning one level of lightness, the color correction data storage part 1 holds 6 pieces of data for an RGB data system as a signal system inside the device. For example, when a pattern 4 for color correction at the high level of lightness is required, gamma correction is performed to 6 pieces of pattern data for color correction while using a liquid curve, with which the lightness is improved rather than the actual level, among plural gamma transformation curves generated by a gamma transforming part 2. Then, the light pattern 4 for color correction is prepared by outputting these gamma corrected pattern data for color correction from a recording part 3.

Title: Ground clearance adjustor for automobile
Inventor: NAKAJIMA HITOSHI
IPC: B60G17/052
Filed: 1986-04-14
Abstract: PURPOSE:To prevent the overshoot phenomenon where the actual ground clearance exceeds a set ground clearance range during the adjustment of the ground clearance by varying the ground clearance sampling time according to the case when the actual ground clearance is within the set ground clearance range or not. CONSTITUTION:The ground clearance is adjusted to a set value by supplying and discharging fluid into an actuator for adjusting the ground clearance which is arranged between each wheel and the body of a car. A ground clearance detecting means A is installed, and the detection output is sent into a sampling means B, and the sampling measurement value of the ground clearance is outputted as a signal at a prescribed sampling time. In a control means D, supply and discharge of the fluid into the actuator C for adjusting the ground clearance is controlled when the signal is input, according to the signal supplied from the sampling means B, so that the actual ground clearance becomes equal to the set ground clearance. When the ground clearance is outside the set ground clearance, the sampling time interval is reduced by a sampling time changing means E.

Title: Fuel injection timing control apparatus
Inventor: TATE TAKAO
IPC: F02M41/12
Filed: 1992-04-07
Abstract: PURPOSE:To cause a fuel injection timing to coincide with a normal fuel injection timing. CONSTITUTION:Fuel is fed into a fuel chamber 7 through operation of an engine- driven fuel supply pump 2, and supplied into a pressurizing chamber 24 via a fuel supply passage 25 whereupon the fuel within the chamber 24 pressurized by a plunger 11 is fed into a fuel injection valve 29. The fuel injection timing is controlled by operation of a timer 19. The bulk modulus of the fuel in the chamber 24 compressed by the plunger 11 is estimated from the fuel temperature of the fuel chamber 7. A duty-ratio control is made of an opening/closing control valve 22 of the timer 19 to expedite the timing with which compression of the fuel is started with the plunger 11, in corresponding relation to the degee by which the bulk modulus becomes smaller.

Title: Liquid crystal display device
Inventor: ISHIHARA TERUHISA
IPC: G02F1/1333
Filed: 1989-04-05
Abstract: PURPOSE:To obtain a bright liquid crystal display device with good visibility by allowing a user to put on and use a display-side polarizing plate between a couple of polarizing plates directly. CONSTITUTION:A rear polarizing plate 3 and a reflecting plate 4 are stuck on a liquid crystal cell 1 and a front polarizing plate 2 is arranged separately from the liquid crystal cell 1 so that the user puts on and uses the front polarizing plate 2. Thus, when the front polarizing plate 2 is separated from the liquid crystal 1, light which is made incident on the liquid crystal cell 1 is not linearly polarized light. Further, the incident light does not pass through the front polarizing plate 2, so the light is not absorbed by the front polarizing plate 2. Consequently, the incident light is made incident directly on a liquid crystal panel 1, so the shadow of a display pattern is eliminated and the brightness of the background increases, so the liquid crystal display device which has the superior visibility is obtained.

Title: Programmable controller
Inventor: YOSHIKAWA NORIO
IPC: G05B23/02
Filed: 1983-05-18
Abstract: PURPOSE:To monitor easily the actual control flow of a user program including a branch instruction by starting the tracing when the instruction containing the designated input/output number is executed in the designated number of times. CONSTITUTION:An RAM6 stores the input/output number A which specifies the tracing start point and the number of executing times of the number A together with the input/output number B which specifies the tracing subject. A CPU4 counts the number of executing times of an instruction including the number A and produces a tracing start command when said executing frequency reaches N. When the number A or B is executed in replay to the tracing start command, the address or contents of the command is stored in the RAM6 and also displayed to a display device 7A. Thus it is possible to monitor easily the actual control flow of a user program including a branch instruction.
