Abstract: PURPOSE:To provide the subject compact drive mechanism of a combine, capable of driving its threshing feed chain so that the speed may be changed following a speed change of a pretreatment unit accompanying a change of running speed while preventing the chain from loosening. CONSTITUTION:The rotational force of a rotation-driving shaft 15 for driving a pretreatment unit linked through a transmission belt 13 to the output shaft 10a of a running-speed change gear 10, is transmitted in the form of a driving force through a transmission mechanism 19 composed of a transmission belt 16, rotation-transmission shafts 17 and 18 and a feed chain-driving mission 5a to a chain sprocket 26 for driving a threshing feed chain. The chain sprocket 26 is arranged on the terminal side of conveyance of the threshing feed chain 5 so as to act on this terminal side 5 for driving the chain 5. Since the rotation- transmission shaft 18 is arranged on the side of a thresher 7 in the forward- backward direction of the machine body, the part of the transmission mechanism 19 corresponding to the side of the thresher 7 can be compacted.

Title: Hydraulic suspension device
Inventor: TAKAHASHI HAJIME
IPC: B60G17/015
Filed: 1993-02-18
Abstract: PURPOSE:To provide a hydraulic suspension device capable of car height adjustment in a short time, even when an oil amount in an accumulator as an oil supply source and a strut cylinder is nil or substantially small, and car height is extremely small. CONSTITUTION:Regarding a hydraulic suspension device equipped with a gas sealed type main accumulator 4 as an oil supply source for feeding oil to a strut cylinder 3 and a hydraulic pump 7 for feeding oil to the accumulator 4, a pressurizing force for sealing gas into the accumulator 4 is at least set higher than the internal pressure of the cylinder 3 in standard height under no load. According to this construction, when the hydraulic pump 7 begins to operate in a case where an amount of oil accumulated in the accumulator 4 and cylinder 3 is nil or substantially small and car height becomes extremely small, oil is preferentially fed to the cylinder 3, thereby causing standard height to be restored in a short time.

Title: Method for controlling charge amount of toner
Inventor: IWAMOTO YASUTAKA
IPC: G03G9/097
Filed: 1990-03-05
Abstract: PURPOSE:To enable an electric charge amount of a toner to be controlled continuously and quantitatively without staining a photosensitive body and a carrier by mixing an amine derivative or a phenol derivative with the toner and introducing ozone or ultraviolet rays. CONSTITUTION:The charge amount to be applied to the toner is controlled by mixing the amine derivative or phenol derivative with the toner and introducing ozone or ultraviolet rays. When the toner is exposed to ozone, since the ozone becomes a donor and the toner becomes an acceptor, the toner is liable to be negatively charged, and the positive toner tends to decrease in the absolute value of the charge amount, and the negative toner tends to increase. When the toner is exposed to the ultraviolet rays, since the toner is oxidized and liable to become negative, the positive toner tends to decrease and the negative toner tends to increase, thus permitting a favorable charge controlling effect to be obtained.

Title: Anodic oxidation method of thin-film pattern
Inventor: MATSUMARU HARUO
IPC: H01L21/316
Filed: 1989-03-08
Abstract: PURPOSE:To prevent defects such as blow-out of a metal even if adhesion properties of a photo resist film become weak due to influence of an electrolytic solution and it is released by providing an insulation film at the lower part of the photo resist film when forming a mask pattern with the photo resist film and performing anodic oxidation. CONSTITUTION:An Al wiring pattern 2 is formed on a glass substrate 1, a photo resist pattern 2 is formed at a specified position of this Al wiring, a first anodic oxidation is performed in this state, and then a photo resist film 3 is eliminated. Then a part which is not subjected to anodic oxidation is selectively covered by a photo resist film 5 and then anodic oxidation is performed again by placing the edge part of the film 5 onto a film 4 which is subjected to anodic oxidation at low voltage, thus eliminating the photo resist film 5. Thus, even if the edge part of the photo resist film is released during anodic oxidation, the metal surface is not exposed and the film has withstand voltage electrically since the part is made of an insulating material, thus preventing fusing-and-cutting of metal due to concentration of electric field from occurring.

Title: Two-dimensional coding system
Inventor: MIYATA MASACHIKA
IPC: H04N1/417
Filed: 1980-04-25
Abstract: PURPOSE:To make two-dimensional coding possible by a simple logic circuit by forcibly coding and outputting a distance from either of the previous line and current line without comparing when one line changes several times where the other never changes. CONSTITUTION:Since it is necessary to compare distance P1P2 to P2P3 at point P2, flag 8 is set and the value of run-length counter 6 is stored in run-length register 9. At point P3, the value of counter 6 is compared to that of register 9 and the value with a less number of bits is selected, coded and output. At point P4, the flag is left as it is and the value of the run-length counter is added to that of register 9. Processing at point P5 is the same as that at point P3. At point P6, the same processing as that at point P4 is performed. Since the previous change point appears at the current line at point P7, flag 8 is reset and relative positions of points P6 and P7 are output being coded. In this processing, if a succession of changes occurs on the current line like at points P3 and P4, distance P1P2 is not compared to P2 and P5, so that coding will be possible only by providing a single register.
