Title: Formation of microstructure and device therefor
Inventor: HASEGAWA TAKESHI
IPC: H01L21/3205
Filed: 1993-07-13
Abstract: PURPOSE:To enable both the formation of a microstructure of nm width level and the production of quantization devices by forming a first metal thin film and a second crystal on the surface of a semiconductor under specific conditions. CONSTITUTION:While the surface 1 of a semiconductor shown in Figure (a) is heated, the first metal is vapor-deposited on the surface 1 and the surface diffusion is effected to form the structures 2, 3 shown in Fig. (b) rearranged along the stepped edge. On the way of growth of the second crystal on the semiconductor surface 1 at the base temperature T, the temperature T is set higher than the temperature T1 at which the particles of the second crystal can diffuse on the first metal thin film but lower than that T2 at which the first metal vaporizes to form the crystal structures 7, 8, 9 shown in Figure (c) only on the terraces 4, 5, 6 shown in Figure (b) without crystallization of the second crystals on the rearranged structure 2, 3. At the same time, when the minimum line width of the first metal thin film is represented by R, the average resident time of the second crystal particles by tau and the vapor deposition rate by J, the particles are fed at a vapor deposition rate of J<1/(R<2>Xtau) to form the fine structure so that the second crystal may not grow on the first metal thin film.

Title: Picture synthesizer
Inventor: SANO YUSHI
IPC: G06T11/80
Filed: 1988-07-12
Abstract: PURPOSE:To arrange segmented graphics to arbitrary positions, in arbitrary sizes, and at arbitrary angles by performing conversational processing with a displaying screen so that the operability of the title synthesizer can be improved by providing an inverted mapping matrix arithmetic section, shape designating work memory, source picture memory, etc. CONSTITUTION:When a user successively inputs picture operating information while the user watches a displaying screen, an inverted mapping matrix arithmetic section 3 produces a new inverted mapping matrix based on the inputted picture information and a source picture (a 1st picture) is stored in a source picture memory 9. A 2nd picture upon which a picture is superimposed is stored in a designation work picture memory 11. A switching discrimination circuit 18 detects the displaying area of the picture of a segmenting area stored through the shape designating work memory 8 of the memory 10 and controls the switching of an output stage switching circuit 16. As a result, a superimposed picture (a 3rd picture) is obtained. Therefore, segmented graphics can be arranged to arbitrary positions, in arbitrary sizes, and at arbitrary angles by performing conversational processings with the displaying screen and the operability can be improved.

Title: Fuel feed control device
Inventor: HABAGUCHI MASAYUKI
IPC: F02M25/08
Filed: 1994-07-04
Abstract: PURPOSE:To prevent degradation of emission due to release of purge gas into an intake pipe. CONSTITUTION:A fuel quantity detecting part 19 detects a vapor fuel quantity in purge gas out of the flow and the density of purge gas. The detected vapor fuel quantity is converted to a basic fuel quantity supplied from an injection valve 6 by first and second conversion parts 20, 21. It is necessary to reduce the basic fuel quantity in order to perfectly burn the converted vapor fuel in purge gas. A surplus fuel quantity computing part 24 computes the fuel quantity corresponding to the shortage air quantity necessary to burn the vapor fuel in purge gas. A duty deciding part 25 decides the duty ratio so as to reduce the injection quantity of basic fuel corresponding to the shortage air quantity, and supplies it to the fuel injection valve 6.

Title: Disc reproducing unit
Inventor: FUJITA GORO
IPC: G11B7/00
Filed: 1992-06-30
Abstract: PURPOSE:To reduce crosstalk by feeding a reproduction signal obtained from a disc, on which information is recorded at different recording frequencies on adjacent tracks, to an isolation filter. CONSTITUTION:An optical disc 1 is rotated through a motor 2, recording face of the disc 1 is irradiated with a laser beam projected from an optical pickup and reflected light impinges on the pickup 3. Information recorded on the disc 1 is reproduced based on the variation of reflected light with respect to the incident light.

Title: Method for forming pattern on semiconductor wafer
Inventor: ISHIBA TERUAKI
IPC: H01L21/02
Filed: 1990-06-29
Abstract: PURPOSE:To reduce the stress produced in a base film by performing exposure, development, and etching to dicing lines only and, after the photosensitive resist used for the dicing lines is removed, exposing and developing a circuit pattern after another photosensitive resist is applied. CONSTITUTION:After only dicing lines 4 are patterned, the resist used for the lines 4 is removed. As a result, the stress produced in a base film 3 can be dissipated, because the film 4 containing the stress is divided into small areas by the dicing lines 4. Then the second resist is applied and circuit patterning is performed. When the stress produced in the base film 3 is large, the second resist tends to be peeled off. When the dicing lines 4 are formed first, etching in the lateral direction can be suppressed.

IPC: G06F3/06
Filed: 1988-07-11
Abstract: PURPOSE:To reduce overheads of commands by positioning tape marks for plural files skipped by one command. CONSTITUTION:The command for specifying the number of tape marks to be skipped, which is issued by a host CPU 11, is decoded by a command decoder 15 via a channel 12 and an interface control part 14, and a space counter 16 is informed of the completion of decoding via a signal line 20, a MPU 17 and a signal line 21. The number of tape marks to be skipped is stored via buss 22 into the counter 16. The command decoder 15 is informed of the receipt of data by the counter 16, which is then operated to subtract what the MPU 17 instructs for subtraction from the number of tape marks until zero. A tape mark detecting is instructed to a read/write control part 18 according to the decoding notification from the decoder 15 by the MPU 17, which also instructs the counter 16 about the subtraction and then instructs a TM detector 19 to stop its detection when the count value becomes zero.

Filed: 1986-07-25
Abstract: PURPOSE:To reduce the size and cost of a device by forming plural images of objects on the photodetection surface of a single image pickup means at the same time. CONSTITUTION:When a lighting switching means 14 is so switched as to connect lighting means 7 and 8 to power sources 13a and 13b, both leads 3a and 3b as inspected surfaces of an IC1 are lit by the means 7 and 8 at the same time. Reflected light from the image on the side of the lead 3a is reflected by mirrors 17, 18, and 19 of a 1st optical system 15 and enters an image sensor 5 through a lens 6 to form the image of the lead 3a on the photodetection surface. At the same time, reflected light from the lead 3b is reflected by mirrors 21, 22, and 23 of the 2nd optical system 16 and enters the image sensor 5 through the lens 6, so that the image of the lead 3b is formed on the photodetection surface. Therefore, the images of both objects of the leads 3a and 3b are formed on the photodetection surface of the same image sensor 5 and picked up, so only one image pickup means is required for plural objects to be picked up and the device is reduced in size and cost.
