Title: Image forming device for wet developing
Inventor: KUROTORI TSUNEO
IPC: G03G15/10
Filed: 1989-09-22
Abstract: PURPOSE:To prevent a stain on an optical system due to developer mist by generating a gas flow from a space side where the optical system exists at the aperture of the passing part of recording image light to the space side where a photosensitive material exists and using a developer in which a toner including a coloring agent is dispersed in a carrier solution including a component with a high boiling point. CONSTITUTION:Since an air current generating means 90 generates at least the gas flow from the space side where the optical system 10 exists at the aperture 19e of the passing part of the recording image light to the space side where the photosensitive material 21 exists, the progression of gas from the space side where the photosensitive material 21 exists to the space side where the optical system 10 exists can be blocked. Thereby, no developing mist generated in the neighborhood of the photosensitive material 21 is moved to the space side where the optical system 10 exists, which prevents the stain of the optical system 10 occurring. Furthermore, since the developer is made as the one in which the toner including the coloring agent is dispersed in the carrier solution including the component with high boiling point, the developer itself is hard to evaporate, and the amount of evaporation of the developer can be reduced in an image recording processing, and the stain of the optical system can be reduced.

Title: Progressive scanning converter and its method
Inventor: KUBOTA KENJI
IPC: H04N7/01
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To convert an interlace scanning video signal by converted with a 3-2 pull-down into a progressive scanning video signal without deterioration in image quality. SOLUTION: An in-field interpolation circuit 4 generates an in-field interpolation signal from scanning lines spatially on and beneath a scanning line to be interpolated in a current field. A matching detection circuit 6 generates 1st and 2nd matching signals that represent matching between the current field and a preceding field and a succeeding field by generating a difference of a low frequency component in a vertical direction between the in-field interpolation signal a preceding/succeeding field signal temporally before and after the current field. A mixing circuit 5 uses a mixing coefficient M that is a difference between the 1st and 2nd matching signals to mix the preceding/succeeding field signals.

CONSTITUTION:The photoresist pattern 2 is formed by coating a substrate 1 with the photoresist, and then exposing it through a mask 7 comprising a transmitting part 10, a transmitting part 11 for forming a mask and a shade part 9 followed by dissolving only an exposed part with a developer to remove said resist part. And then, the 1st coloring matter layer is laminated on the photoresist pattern 2, and then said resist pattern is removed, thereby forming the pattern 4 of the 1st coloring matter and the alignment mark 12 having the same coloring matter to that of the 1st coloring matter layer. The 2nd coloring matter layer is formed by repeating a prescribed step after positioning of the mark 7 through the mark 12.

Title: Video signal switching system
Inventor: TAKAHASHI KIMIHIDE
IPC: H04N5/93
Filed: 1985-11-06
Abstract: PURPOSE:To prevent the appearance of switching noise due to switching to a picture by performing the switching of a magnetic head setting a horizontal synchronizing adjacent to a horizontal scanning period at preceding several periods before a vertical synchronizing signal is generated as a reference. CONSTITUTION:The step waveform of a PG pin detection signal is inputted to a synchronization circuit 12 by a PG coil 3, then it is synchronizing-separated at a synchronizing separator circuit 10, and a horizontal synchronizing signal Hsync which is shaped in waveform is inputted. Thereby, the synchronization circuit 12 generates the switching signal of a switch 6. As a result, even when the PG pin is detected at before seven Hs of the vertical synchronizing signal and the detection signal is issued, the switch 6 is not switched at the output time of the detection signal, the switch 6 is changed over at just after horizontal synchronizing signal. So that the switching noise is present at a horizontal blanking period, the switching noise does not appear on the picture even when the vertical high voltage side of a receiver is lowered or an overscanning quantity is reduced.

Assuming that the current position of the vehicle is P1(X1, Y1), it is decided whether the vehicle travels straight according to the deviation angle of the azimuth sensor 2 as an angular speed sensor and when it is decided that the vehicle travels straight, a PDOP value corresponding to the P1(X1, Y1) is extracted by proper arithmetic and this value is used as a weight coefficient to calculate the absolute travel direction of the vehicle by the arithmetic unit 62 in the data processor 61. Then every time the current position of the vehicle based upon the GPS position measurement is indicated, the initial set error of the azimuth sensor 2 is properly corrected.

Title: Semiconductor memory
Inventor: HASEGAWA TAKEHIRO
IPC: G11C11/409
Filed: 1994-09-17
Abstract: PURPOSE: To reduce power supply noise by providing a circuit for decreasing the driving capacity of a sense amplifier driver at the time of writing as compared with reading thereby reducing the current accompanied with sense operation at the time of writing. CONSTITUTION: Two pMOS transistors and two nPOS transistors are prepared as a sense amplifier driver. In the nMOS and pMOS transistors 2, a BSEP operates with 'L' at the times of both reading and writing. On the other hand, writing of an nMOS transistor 3 and a pM0S transistor 4 is disabled by a BRSTR signal which goes 'L' at the time of writing. Since the driving capacity of sense amplifier driver is decreased at the time of writing as compared with reading, the current accompanied with sense operation at the time of writing can be decreased without varying the sense speed at the time of writing thus reducing the power supply noise.
