Abstract: PROBLEM TO BE SOLVED: To make it possible to not only automatically set a scan direction with an upper/lower detection part and also to change the scan direction by the instruction of a user by providing a means for instructing the scan direction form the outside and deciding whether any one between the instructions from an upper/lower left/right decision part and the outside is preferred. SOLUTION: The upper/lower and left/right judging part 6 judges upper/lower and left/right of a fitting direction of a display device, and informs a priority control part 5 of the fitting direction of the display device according to usefulness/idleness of a signal. An external control input part 7 instructs the priority control part 5 on the scan direction from the outside similarly to the upper/lower and left/right judging part 6. The priority control part 5 informs a shift direction switch part 4 either one side of the signals from the upper/ lower and left/right judging part 6 and the external control input part 7 according to a prescribed priority order decision method.  The shift direction switch part 4 instructs a vertical direction drive part 2 and a horizontal direction drive part 3 the scan direction, and makes a liquid crystal display device display an image in a required direction.

Filed: 1980-06-12
Abstract: PURPOSE:To reduce the data speed, by shifting the sampling timing by half pitch for every two horizontal scans of a video signal as for the sub-Nyquist sampling and varying the predicting system in the even- and odd-numbered horizontal scanning periods for the differential predictive coding. CONSTITUTION:The picture elements (circle marks) are sampled from the waveform of a video signal in horizontal scans 2l-1-2l+2 and by shifting the sampling timing by half pitch with every two horizontal scans of the video signal. In such  way, a 1/4-offset relation is secured between the sampling frequency and the horizontal scanning frequency. Thus the video signals shown by the broken lines are obtained by the correlation of the video signals and by inserting the picture element is  row preceding by just two horizontal scans into each picture element in row. In the  case of an even-numbered horizontal scanning line, a highly precision prediction is  possible with a 2-dimensional prediction since the degree of correlation of each of the picture elements (h), (i) and (j) is higher than the picture element Xe. While a highly precision prediction is possible through a 1-dimensional prediction for an odd- numbered horizontal scanning line since the degree of correlation of the picture element (m) is higher than the picture element Xo.

Title: Terminal treatment method of panel-integrated extrusion molding
Inventor: TODAKA NOBUHIKO
IPC: B60J1/00
Filed: 1995-04-04
Abstract: PURPOSE: To reduce cost by eliminating the post-mounting of a separate piece or postforming. CONSTITUTION: Molding 2 is extruded so as to make a round of the peripheral edge part from the starting point on the peripheral edge part of a panel 1 to a terminal point, which exceeds the starting point in order to form an overlapped portion 24, which is formed by overlapping the molding starting end part 22 with the molding terminating end part 23. Under the state just mentioned above, by cutting the overlapped porting 24 at a cutting point between the starting point and the terminal point, the respective ends of the molding starting end part 22 and the molding terminal end part 23 are cut off so as to form a frame-like shape. Since no gap is produced between the starting end and terminal end, time and labor for bonding a separate piece becomes unnecessary.

Title: Manufacture of semiconductor integrated circuit
Inventor: TAKASHINA REIJI
IPC: H01L27/04
Filed: 1992-02-29
Abstract: PURPOSE:To prevent step-cut and residue of electrode metal, by working the side wall section of a polysilicon layer for a resistor after etching, into a taper type. CONSTITUTION:After a layer wherein a lot of N-type impurities are ion- implaned in a polysilicon layer 22 formed on a P-type semiconductor substrate 1 is formed and heat-treated at a high temperature, the polysilicon layer 22 is etched and worked into a pattern having at least two or more kinds of film thickness. A polysilicon layer for a resistor is annealed at the same time when an emitter diffusion layer 16 is formed. Thereby the polysilicon layer for a resistor can be annealed at the same time when the emitter diffusion layer is formed, so that annealing at a high temperature is enabled as compared with the conventional method. As the result, impurity concentration in the polysilicon layer can be made uniform, so that the sectional shape of the side wall of the polysilicon layer after etching can be improved to be a taper shape from an inverse taper, and step-cut and residue of electrode metal can be completely excluded.

IPC: G01C19/72
Filed: 1982-05-12
Abstract: PURPOSE:To detect rotating directions, by adjusting and arranging the directions of the end surface of a plane of polarization preserved optical fiber, a polarization beam splitter, and a 1/4 wavelength plate so that the optical fiber as a phase piece having retardation DELTAepsilon acts on linear polarization in the bearing of 45 degrees. CONSTITUTION:Laser light from a laser light source 1 is completely linearly polarized by a polarizer 2. The incident bearing of the light is adjusted by a 1/2 wavelength plate 3. The light, which is inputted into a plane of polarization preserved optical fiber 6 from both directions and outputted, is returned from a polarization beam splitter 5 and transmitted through a 1/4 wavelength plate 7. Then the light reaches a light detector 8. When the phase advancing axis or phase delaying axis of the 1/4 wavelength plate 7 is arranged in the bearing equal to the bearing of the incident linearly polarized light, the light reaching the light detector 8 becomes the linearly polarized light having 1/2DELTAalpha. The detected light 8 is adjusted in advance so that the extinction state is obtained when DELTAepsilon=0, i.e. the plane of the polarizaion preserved optical fiber 6 is in a stationary state. When the light detector 8 is rotated whe DELTAthetanot equal to 0 so that the extinction state is obtained, DELTAtheta can be obtained from a rotary angle.

Abstract: PURPOSE:To suppress noise by fitting a sound absorbing material into the upper part of the inside of a silencer body and installing a diffuser which crosses at right angles with the axis of the body onto the lower part and covering the lower outer peripheral surface by a sound shielding material. CONSTITUTION:A sound absorbing material 2 having exhaust holes 3 is fitted into the upper part of a silencer body 1. A diffuser 2 which crosses at right angles with the axis of the body 1 and has a number of holes 9 on the outer peripheral surface is installed onto the lower part of the body 1. The lower outer peripheral surface of the body 1 is covered with a sound shielding material. The steam sent into the body 1 is converted into the sound in a high frequency range through the dispersion by the diffuser, and decelerated by the sound absorbing material, and then discharged. Therefore, noise can be suppressed in a wide band range.
