Title: Method for leading out set-off paper in coil
Inventor: MIZUTA KEIJI
IPC: B21C47/18
Filed: 1989-07-20
Abstract: PURPOSE:To normally coil a set-off sheet by sending a thin strip to the upper side of an opener and then bringing the end of the opener into contact with the lower surface of the thin strip to peel the set-off sheet in a payoff of a metal thin strip coil in which the set-off paper is inserted. CONSTITUTION:After the end of the base sheet 3 is lead out on the upper side of the opener 6, the end of the opener 6 is held up and brought into contact with the lower surface of the base sheet 3. When a coil 2 is driven under such a state, though the set-off sheet 4 sticks to the lead-out base sheet 3, it receives a shearing force, is peeled from the base sheet 3 and falls under the opener 6. Then, if the coil 2 is driven for rotation, the end of the set-off sheet 4 is sent out to the lower side of the opener 6. Thus, the guard sheet can be sent out normally.

Title: Bus protective relay device
Inventor: MURAKAMI YUICHIRO
IPC: H02H3/28
Filed: 1987-07-28
Abstract: PURPOSE:To accelerate by stopping the secondary current of a current transformer and simultaneously forcibly resetting the holding of a suppression amount under the conditions that an AND condition of a breaker opening state of a trouble channel and a trouble detecting state by the operation of a bus side trouble detecting relay is satisfied continuously for a predetermined time. CONSTITUTION:If a blind trouble occurs at the time of t1, a trouble current flows, but since a current equal to the magnitude of the sum of flowing currents is fed to a bus protective relay device. Thus, an operation amount ld is not generated, but only a large suppression amount is generated, and a relay output remains inoperative. Then, as a blind protective system, when the introduction of the secondary current of a current transformer set in the trouble channel is stopped at the time of t2, the current flow is eliminated. Accordingly, an operation amount Id is generated, and a scalar sum IR is reduced. Simultaneously, in order to forcibly reset a suppression amount holding, the ratio difference of the amount Id and the suppression amount IR is calculated. Therefore, a relay operation can be performed effectively at a high speed.

Title: Automobile part water repellent glass and manufacture thereof
Inventor: AKAMATSU YOSHINORI
IPC: B60J1/00
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To suppress secular changes in optical performance and external appearance by a long time sliding action of door glass by forming water repellent films except a part receiving sliding by a stabilizer related to an elevating/ lowering mechanism for glass, in water repellent glass with formed water repellent films on an outside surface of door glass. SOLUTION: In an automobile door, stabilizers for guiding smooth glass elevating/lowering motion are incorporated so as not to vibrate glass at the time of an elevating/lowering operation for door glass. When the door glass is made water repellent glass, water repellent films are prevented from being formed in a part slid by the stabilizer which is extremely violent in a sliding action. Namely, when only a pair of stabilizers are disposed, a band-shaped area (black painted part) including the stabilizers is made as a part in which water repellent films are not formed. When water repellent glass is manufactured, a masking material is adhered to the part in which the water repellent films are not formed and a treatment is performed so as to form water repellent films on the whole surface of door glass.

Abstract: PURPOSE:To reduce memory capacity by changing image pickup resolution at need by varying voltage increasing ratios in all areas out of the area with a cycle arriving at the peak voltage value of a sawtooth wave voltage which deflects the locus of an electron beam. CONSTITUTION:An image pickup area A image-picked up with an image pickup tube 1 is formed in rectangle, and rectangular areas B including the two sides of a corner part are demarcated at four corners, and the areas B are scanned with the electron beam at speed so as to read an image with required resolution. Also, in a cross area C other than the area B, by accelerating the scanning speed of the electron beam by increasing the increasing ratio of a voltage to be applied on deflecting coils 7 and 8 with a control circuit 11, image pickup can be performed intermittently in the area, and the information quantity of the image is decreased, then, the resolution is decreased. Thus, the image information of one subject when high resolution is requested can be suppressed to a required minimum, and the storage efficiency of a memory circuit can be heightened by increasing the amount of data of the subject to be housed in the memory circuit.

Abstract: PURPOSE:To prevent the burden of catalysts and to improve purification effect by providing a gasifying phase just in front of a catalyst bed where the temp. of untreated waste gases is highest and oxidizing non-gaseous org. compds. catalytically after gasifying the same. CONSTITUTION:A gasifying phase is a layer of granular carriers or monolithic type honeycomb carriers consisting of active alumina such as gamma alumina and is installed in front of catalyst beds. The waste gases removed of coarse particles in a dust collector 2 are heated to a prescribed temp. in a heating chamber 3, and are finally introduced into a catalytic reactor 4.

Thus the sticking of the fine particles to catalysts is prevented, and the harmful gases are purified by catalytic oxidation and are released into the atmosphere by a gas releasing fan 8.
