Title: Original reader
Inventor: HORIUCHI TAKAO
IPC: H04N1/12
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To eliminate blurring of an image which is caused by an unstable factor of a driving mechanism by performing a comb-line after processing and an integration calculation processing for image data of a read reference chart part. SOLUTION: An image reading means reads a chart 17, in which white lines and black lines are arranged alternately side by side at equal intervals, so that the horizontal direction of the chart 17 is a vertical scanning direction of the image reading means. Next, data for one line is extracted from image data of the read chart 17 in the direction of horizontal scanning with one pixel width in the vertical scanning direction. In such a case, the speed fluctuations in the vertical scanning direction of the image reading means appears as density change of read image data. By detecting the density change, a speed fluctuation analysis in the vertical scanning direction of the image reading means is performed. Thus, a comb-line filter processing and an integration calculation processing for image data of a reference chart part are performed.

Title: Arithmetic method for lateral acceleration of vehicle
Inventor: ISODA KEIJI
IPC: B60T8/172
Filed: 1989-12-25
Abstract: PURPOSE:To speedily and accurately obtain the lateral acceleration by finding the lateral acceleration from the speed difference between a left and a right coupled driving wheel and the travel speed of the vehicle, calculating a correction coefficient for variation in the effective radius of the coupled driving wheels, and correcting the lateral acceleration. CONSTITUTION:Sensors 26 and 27 finds the speed difference Dr between the coupled driving wheels 24 and 25 and the vehicle speed V by a TCL 22 and calculates ideal acceleration Gr in consideration of the treads of the wheels. Further, the Gr is corrected with the correction coefficient K for variation in the effective radius of the right and left tires in turning to calculates real lateral acceleration G'r. The coefficient is obtained by experimentation. The TCL 22 instructs and ECU 13 to reduce the output of the engine when G'r >=Gr1. A motor 17 stops down the throttle valve to reduce the engine output and thus reduce the G'r. When G'r < Gr2 << Gr1, the control is reset. With the Gr2, neither rolling nor yawing is caused and this constitution improves the steering stability.

Title: Projection type display device
Inventor: MIYATAKE YOSHITO
IPC: G03B21/60
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To provide a projection type display device in which a large increase in the cost is prevented, moire fringes are made unrecognizable and the picture quality is improved. SOLUTION: The spatial frequency of moire fringes is determined by the differences between the spatial frequency of the periodic structure of the projected picture and its higher harmonics and the spatial frequency of the periodic structure of the screen. A moire wavelength L is given by 1/L=|1/S-n/Q| where S is the periodic structure of a screen, (n) is the order of higher harmonics and Q is the picture element pitch of the projected picture. If the above equation is normalized by Q, it becomes 1/(L/Q)=|1(S/Q)-n|. This equation shows the relationship between L/Q and S/Q. If S/Q is given, the moire wavelength of each order (n) is obtained. If (m) is a positive integer, the longest moire wavelength becomes a minimum at the cross point of a curve n=m and a curve n=m+1.  In the above equations, let n=m and n=m+1, them the longest moire wavelength becomes the minimum for Q/S=n+1/2.
