Title: Display apparatus of current position of moving body
Inventor: IIBOSHI AKIRA
IPC: G01C21/00
Filed: 1989-06-26
Abstract: PURPOSE:To enable a user to recognize how correctly the present position of a moving body is indicated by indicating the matching ratio when the present position of said moving body outside a road on a map is displayed onto a road by which the matching is effected. CONSTITUTION:The present position of a moving body is obtained by a signal processor 3 on the basis of signals from a distance sensor 1 and a direction sensor 2. The present position is stored by a running locus memory device 4. At the same time, the present position is indicated onto a display device 7 together with the map information stored in a memory medium 5. When the obtained present position of the moving body is outside a road on the map, the signal processor 3 makes pattern matching so that the running locus matches the road. The once-obtained present position is corrected onto a road matching the running locus, which is then displayed. At this time, the matching ratio is also indicated on the display device 7.

Title: Selective oxidation of semiconductor substrate
Inventor: HAYASHI HISAO
IPC: H01L21/316
Filed: 1985-07-25
Abstract: PURPOSE:To dispense with bird's beak and bird's head by a method wherein a part whose oxidation speed is fast and a part whose oxidation speed is slow are selectively formed on a substrate, and selective oxidation is performed after the oxide film formed on the part whose oxidation speed is slow has been made an acid-proof mask. CONSTITUTION:A resist 2 is arranged on a substrate 1 to etch the surface of the substrate other than the position where the resist is arranged. The crystal on the etched substrate is broken to form a damaged layer 4. Then, the resist 2 is removed to expose the unoxidized surface of the substrate. The unoxidized surface of the substrate and the damaged layer 4 are oxidized to form an oxide thin film 6 and to make the damaged layer 4 an oxide thick film 5. Further, the oxide thin film 6 is made an acid-proof mask 7 by a method such as nitrification, and then, the oxide thick film 5 is oxidized to remove the acid-proof mask 7. By this method, the selective oxidation method producing no bird's beak and no bird's head is realized, thereby reducing the whole processes.

Title: Document transfer device
Inventor: HIROKI MASASHI
IPC: B65H1/30
Filed: 1987-06-30
Abstract: PURPOSE:To prevent document from being fed in duplicate by keeping the distance between a document transfer roller and a separation roller to be in contact with the transfer roller constant when the document is placed in a tray and varying the distance when the document is transferred. CONSTITUTION:Multiple sheets of document are placed on a tray 48. A transfer roller 51 and a separation roller 55 to be in contact with the transfer 51 and rotating in the direction opposite to that of the transfer roller 51 are provided. The transfer roller 51, being pressed downward with a spring 54 attached to the front end of an arm 53 rotating about a pivot shaft 52, keeps the distance between the transfer roller 51 and the separation roller 55 constant. Swinging up and down a takeout roller 57 at the front end of an arm 56 attached to a shaft 51a of the transfer roller 51, the document G is transferred one by one to a next process via guide rollers 59, 60. The upward movement of the arm 56 is restricted with a stopper 58. This prevents the document G from being transferred in duplicate at a time. Strong friction between the document G and the both rollers 51, 55 is reduced so that the life of the rollers 51, 55 is extended.

Title: Load sharing system
Inventor: HARAFUJI YOSHIHIKO
IPC: G05F1/00
Filed: 1984-08-02
Abstract: PURPOSE:To reduce the variance of a load current by allowing each power source to have a negative output resistance characteristic when plural power sources are operated simultaneously and allowing power sources which are not stopped to have non-negative high or low output resistance characteristics when a part of power sources is stopped. CONSTITUTION:Currents IA and IB transmitted from current sources 10A and 10B are shunt to a current IR flowed to a resistance R and a load current IL. A current detecting circuit 16 detects the current IR. When an output voltage VA is lower than a preliminarily determined voltage, the resistance R becomes a negative resistance to obtain a desired load sharing characteristic; and when the voltage VA exceeds a set voltage, the resistance R becomes a positive resistance to reduce the variance of the load current for operation of one current source. Currents iA and iB transmitted from voltage sources 20A and 20B are flowed to a load through a control circuit 7, and a current detecting circuit 17 detects the current iA. When the output current iA is lower than a preliminarily determined current, the resistance R becomes a negative resistance to obtain a desired load sharing characteristic; and when the current iA exceeds a set current, the resistance R becomes a positive resistance to reduce the variance of the load current for operation of one voltage source.

Title: Corrosion-resistant alloy with high magnetic permeability
Inventor: HAGI CHITOSHI
IPC: C22C38/06
Filed: 1981-10-14
Abstract: PURPOSE:To improve the corrosion resistance of an Fe-Al-Si alloy without deteriorating the superior magnetic characteristics by combinedly adding a Pt group element and S to the Fe-Al-Si alloy. CONSTITUTION:This alloy consists of, by weight, 3-16% Si, 2.5-17% Al, 0.001-4.0% of >=1 kind of Pt group element, 0.001-2.0% S and the balance chiefly Fe. Less than the lower imits of the Pt group element and S do not distinctly produce the effect, and more than the upper limits of them deterioate remarkably the magnetic characteristics and make the alloy impractical. By this method the wear resistance and machinability can be also improved. By further adding an adequate amount of an elemenet such as Ti or V as a secondary component, the corrosion resistance can be improved furthermore by the synergistic effect.

Title: V-belt transmission device
Inventor: HATSUTORI TORAO
IPC: F16G5/16
Filed: 1982-09-22
Abstract: PURPOSE:To reduce wear in both a V-type member and a V-pulley, by making up the V-type member with a core material composed of a metal member and a coating material composed of a friction material excellent in wearproofness and heat resistance, in case of a device consisting of a lot of V-type members. CONSTITUTION:A V-belt consists of a needle roller 4 or a slender roller member installed interposingly between lots of V-type members 7, a flexible endless member 15 clamping tightly the outer circumference of a coupling unit composed of the said V-type members 7 plus the needle roller 14 and a rubber-make endless holding member 16. Since the V-type member 7 is covered with a coating material 9 such as rubber or the like excellent in wearproofness and heat resistance, no contact between metals themselves happens in time of contacting with V-groove of a V-pulley, so that any wear in both the V-type member 7 and the V-pulley will not happen likewise. Moreover, since the needle roller 14 consists of a porous coil impregnated material, wear and friction loss in a contact part between the roller 14 and the V-type member 7 is small as lesser as negligible.

IPC: B29C45/33
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To obtain a highly accurate molded product by a short molding cycle by sliding at least one cavity pieces so as to separate the same from a resin when a molten resin is cooled to below softening temp. to forcibly demarcate a gap between the resin and the cavity piece. SOLUTION: A mold is heated to be held to temp. lower than the softening temp. of a resin and the molten resin heated to its softening temp. or higher is injected into a cavity 15 to fill the cavity and resin pressure is generated on the transfer surfaces 11a, 12a of cavity pieces 11, 12 to cool the mold. In this stage, when only the cavity pieces 13, 14 are slid in the direction shown by an arrow and gaps 17a, 17b are generated between the resin 16 and the cavity pieces 13, 14 to advance cooling, the resin part facing to the gaps 17a, 17b is preferentially shrunk and deformed as compared with the parts being in close contact with the cavity pieces 11, 12. The close contact force of the resin 16 with the cavity pieces 11, 12 is kept and the generation of a sink on the transfer surfaces is prevented.  Transfer can be faithfully performed by a short molding cycle and a molded product reduced in optical elastic strain can be obtained.
