Title: Method for rolling bar stock with special shaped section
Inventor: ENDO HITOSHI
IPC: B21B1/08
Filed: 1991-04-25
Abstract: PURPOSE:To exactly lead a material to be rolled to a grooved roll and to manufacture a rolled stock with high accuracy by bringing the material to be rolled into contact with rolling rolls from a part before a starting position of rolling and executing the part coincidence between the groove of roll and the projecting part of the material to be rolled. CONSTITUTION:For exactly fitting the projecting part of the material 1 to be rolled which is delivered from a delivery reel 6 into the groove on the grooved roll 2, the material 1 to be rolled is pressed against the grooved roll 2 in the part on this side of the rolling part 8 on the surface of the grooved roll 2 with a guide roll 4. The material 1 to be rolled is led by exactly pressing so as to bring into contact longer than the biting length that is necessary for rolling. The projecting part of the material 1 to be rolled is exactly fitted into the groove of the grooved roll 2, the material is rolled with the grooved roll 2 and fellow roll 3 in the rolling part 8 and coiled with a take-up reel 5.

Title: Silicon-containing polymer and molded product using the same
Inventor: UCHIUMI NAOHIKO
IPC: G02C7/04
Filed: 1992-07-15
Abstract: PURPOSE:To provide a silicon-containing polymer also containing specific alpha- substituted acrylate monomer units and useful for contact lenses, intraocular lenses, etc., because of giving the molded products excellent in transparency, shape stability, durability and oxygen permeability. CONSTITUTION:This silicon-containing polymer contains units of formula I (R<1>, R<2> are hydrocarbon groups which may contain Si atoms and/or O atoms, but at least one of R<1> and R<2> is the hydrocarbon group containing the Si atom) in an amount of 10-100mol.% in its all constituting units. The polymer is preferably produced by polymerizing a monomer mixture comprising an alpha-substituted acrylate monomer of formula II and, if necessary, other comonomers in the presence of a polymerization initiator such as acetyl peroxide at 50-120 deg.C for 10-100hr.

Title: Hydraulic controller for clutch
Inventor: HONDA TAKUMI
IPC: F16H61/08
Filed: 1987-07-28
Abstract: PURPOSE:To achieve smooth inter-clutch switching by coupling an orifice and a one-way valve in parallel with a first clutch drain port thereby avoiding such condition where two clutches are blocked when they are switched hydraulically. CONSTITUTION:An orifice 70 is arranged in a drain oil path coupled with a first clutch drain port 62 of a clutch control valve 50, and a one-way valve 71 for allowing oil flow only from the drain port 62 to a second solenoid valve 46 is arranged in parallel with the drain oil path. When a first clutch 20 is disengaged and a second clutch 5 is engaged, hydraulic pressure of the first clutch is discharged through the drain port 62 of the clutch control valve 50. Since the one-way valve 71 is closed upon turning ON of the second solenoid valve 46, hydraulic pressure of the first clutch is discharged only through the orifice 70 so as to loosen falling of clutch hydraulic pressure. Consequently, both clutches are not disengaged simultaneously, resulting in smooth switching of clutch.

Abstract: PURPOSE:To make it possible to have a conversation with a communicated user while observing his (or her) eyes by adjacently arranging a camera for photographing a communicating user himself (or herself) and a monitor and displaying the image of the communicated user on a display area close to the camera displayed on the screen of the monitor. CONSTITUTION:The image of a user I photographed by the camera 30 is written in a prescribed area A of an image memory 44. Simultaneously the image is sent to a communicated user II together with a voice signal by a line interface 52 through a coding/decoding circuit 54. On the other hand, an input signal is written in a prescribed area B of the memory 44 by an image control circuit 46 through the circuit 54 and then the images recorded in respective prescribed areas A, B of the memory 44 are respectively displayed on the prescribed areas A, B of the monitor 34. Since the camera 30 is arranged near the area B displaying the image of the communicated user II, the visual line of the user I observing the displayed user II is directed almost to the camera 30, so that a discrepancy between the visual lines of both the users can be reduced and a feeling of conversational disorder can be eased.

Title: Tying band
Inventor: YAMAUCHI MITSUNORI
IPC: B65D63/10
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To easily re-tie without re-welding if a band is cut halfway by forming slits with intervals from respective side ends toward opposite side ends at both side ends of a heat-welding film formed like a tape. SOLUTION: A tying band 3 for binding a coiled wire is cut by an edge tool like a knife when the wire is to be unrolled. After the wire is unrolled by a required length from the coiled wire, the remaining coiled wire is re-tied. In this case, the band 3 once cut is used and again wound around the remaining wire. Ends 3A, 3B are overlaid, and slits 4, 5 formed on the band 3 are engaged with each other for binding. Thus easy and reliable winding is possible without overlapping, heating and re-welding both ends of the tying band 3 which has been once cut.

Abstract: PURPOSE:To prevent damage of an intake passage at the time of generating a back fire by providing a one-way valve, which permits only circulation of combustion gas from the intake passage, in a branch passage provided in the downstream area of a reed valve. CONSTITUTION:A branch passage 20, which mutually communicates with an intake passage 10, extends to the lower and communicates with a muffler, is formed in the downstream area of a reed valve unit 3 in the intake passage 10.
