Title: Buried atom thin wire
Inventor: HEIKE SEIJI
IPC: H01L21/20
Filed: 1993-06-24
Abstract: PURPOSE:To prevent the arrangement of atoms from being disordered due to the effect of a temperature or the like by a method wherein the atoms, which constitute a device, are buried in a groove, which is formed in a crystal face and has a depth and a width of the amount of one piece of an atom to the amount of a plurality of pieces of atoms, and an atom thin wire is formed into a structure where the atom thin wire can stably exist in the crystal face. CONSTITUTION:The surface atoms of atoms 21 constituting a substrate crystal are pulled out and a small groove 22 is formed. Then, atoms 23, which are used for forming an atom thin wire, are made to attract on the substrate surface, a voltage pulse is applied to a probe and the atoms 23 are diffused, whereby the atoms 23 are buried in the groove 22. The probe is moved to other region, a voltage pulse is again applied to the probe to diffuse the attracted atoms 23 left in the vicinity of the groove 22 to other region and the atoms 23 are removed. As this result, attracted atoms 24 in the groove 22 are arranged, are left into a thin linear form and the atom thin wire 25 is formed. As the wire 25 is buried in the groove formed in the surface of the substrate crystal and can stably exist in the substrate surface, it is used as the smallest electronic circuit constituent element, which is though in principle, and a far higher-density circuit can be constituted compared to an integrated circuit formed using a conventional process.

Title: Decoding device for high efficiency code
Inventor: KONDO TETSUJIRO
IPC: H04N19/00
Filed: 1986-06-30
Abstract: PURPOSE:To reduce jerkiness that occurs when a block changes by replacing with the mean value of the data of the last area of preceding block and the data of the leading area of present block at the time of shifting from preceding block to present block. CONSTITUTION:A movement judging circuit 3 generates the judging code SJ of 1 bit that indicates the presence or absence of movement from data of picture elements at the same position between areas of each frame of a three- dimensional block. To prevent jerkiness at the time of shifting preceding block to the area of a mean value between frams of a still block in time, the receiving side uses the mean value of the data of the area and the data of the area of preceding block at the time of shifting from the area of preceding block to the area of the means value between frames. Thereby, a picture image in which the image information of preceding block and present block are mixed is formed between different blocks continuous in time, and accordingly, the jerkiness can be reduced.

Inventor: HAYASHI YOSHIMASA
IPC: F01L1/16
Filed: 1982-09-03
Abstract: PURPOSE:To reduce valve noise by overlifting the valve at the time of valve lift, eliminating this at the time of seating gradually and thereby providing mild seating. CONSTITUTION:Hydraulic cylinders 15, 16 are formed at the portion of locker arm 12 facing the cam 13 and at the portion of the same facing the valve stem 14, and plungers 17, 18 are fitted in these cylinders 17, 18. The cylinders 15, 16 are in communication with each other, and thereto the oil is fed through a check valve 21. Because the pressure receiving area ratio of these plunger is set at a value larger than the locker ratio, the lift amount specified by the lift curve for the cam 13 is exceeded, and even when the cam lift has become zero, the valve will not seat entirely, whereafter the lubricating oil is gradually compressed by the pushing force of the valve spring so as to permit seating just when the overlift is eliminated.

Title: Solar heat collector
Inventor: KONDOU TAKEYA
IPC: F24S10/50
Filed: 1983-08-22
Abstract: PURPOSE:To prevent a stabilizer in a solar heat collector body from dispersing at the time of heat collecting or the like, to prolong the life of the solar heat collector, and to make it stable against a heating medium, by providing a heat- resistant synthetic resin thin layer on the surface of the solar heat collector, and using a polyethylene layer as a circumferential wall section of a passage. CONSTITUTION:As the solar heat collector 10 has a heat-resistant synthetic resin film 12 on the upper surface of a solar heat collecting body 11, a stabilizer present in the polypropylene that constitutes most of the solar heat collecting body 11 can be prevented by the heat-resistant synthetic resin film 12 from dispersing, and therefore the heat deterioration due to the dispersion of the stabilizer can be prevented. By the prevention of the dispersion, the stabilizer can be prevented from adhering to the undersurface of a cover glass, and the problem that worsens the efficiency for collecting solar heat can be avoided. As a circumferential wall section 14 of a passage 13 consists of a polyethylene such as a high-density polyethylene or the like that is stable in view of the molecular structure, the stabilizer present in the polypropylene can be prevented from dissolving into the heating medium flowing in the passage 13.

Title: Load adjusting device of valve spring
Inventor: ADEGAWA MAKOTO
IPC: F01L1/46
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To increase the set load of a valve spring to obtain a large braking effect when an exhaust brake is applied, by providing between a valve spring of an exhaust valve side and a cylinder head a lifting means for compressing a valve spring by raising a stroke by required one through a screw feed action. SOLUTION: When an exhaust brake switch is turned on, an exhaust shutter disposed in an exhaust pipe is shut to turn a female-threaded cylinder 14 by the action of an actuator 21 by a specified angle via a drive lever 18, whereby a moving-up/down screw 17 screwed in the female-threaded cylinder 14 is moved up by the feed action of the screw by a specified stroke to compress a back spring 7 to an increased set load, which increases the upward energizing force (valve closing force) of an exhaust valve 3. Therefore, when an exhaust brake is applied, the exhaust valve 3 is prevented from being opened forcibly during an intake stroke and hence the pressure in the exhaust pipe is prevented from reversibly flowing into the cylinder and an intake port side, and a large braking effect is produced.

Title: Steering device for conveying metal plate
Inventor: HARADA MASAHIRO
IPC: C23C2/00
Filed: 1986-07-02
Abstract: PURPOSE:To prevent any flaws to a metal plate surface and its deformation from occurring, by installing at least a pair of liner motors being set up in a conveying direction of the metal plate in the width direction with a constant clearance with the metal plate, and generating a shifting magnetic field in a direction to be opposed to each other to the width direction. CONSTITUTION:In the case where a traveling metal plate 1 has shifted (zigzag) in the width direction for some reason or other, an area of the plate 1 to be covered by liner motors 10A and 10B is varied to some extent. And, forces fA and fB acting on the metal plate 1 is increased or decreased in proportion to the area of the metal plate 1 to be covered by these linear motors 10A and 10B. Therefore, push-back force (steering force) in the opposite direction to the moving direction acts on the metal plate 1 in a noncontact state. For this reason, the metal plate is stably travelable without entailing any flaws and deformation in it.
