Title: Production of stamper for disc
Inventor: NEGAMI TETSUYA
IPC: G11B7/26
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To shorten the tact time while eliminating adverse effect of electroforming on the environment by forming a thin metal film on the surface of a resist board and pasting a metal plate having desired thickness and rear surface roughness thereto thereby eliminating the electroforming time and the rear surface polishing time. SOLUTION: A thin conductive metal film 2 is formed on a glass master produced by cutting pits 1b in the surface 1a of a glass substrate 1. The thin metal film 2 is formed by sputtering a metal, e.g. Ni or an Ni alloy, having a small coefficient of thermal expansion and strong against oxidation. Subsequently, a metal plate 4 having predetermined thickness (d) and rear surface roughness is then pasted through an adhesive 3. The adhesive 3 is composed of a thermosetting resin having heat resistance of 350 deg.C or above which is spin coated uniformly onto the sputtered surface and heated after the metal plate 4 is pasted. Alternatively, a reaction setting resin, e.g. epoxy resin, is employed for bonding. Finally, the glass master is stripped to obtain a stamper.

Title: Combustion controller
Inventor: YUKIMURA MASAHIKO
IPC: F23N5/10
Filed: 1984-06-14
Abstract: PURPOSE:To prevent a relatively large ignition sound based on the operation of an ignitor by making the ignitor inoperative when a power source voltage is lowered to less than a predetermined voltage and releasing a forcible holding of the valve opening of an electromagnetic safety valve. CONSTITUTION:When a push button 8 is pushed up to an ignition position B, an electromagnetic safety valve 1, an interrupting valve 4 and an ignition valve 6 are opened. Simultaneously, a relay 22 is actuated by the voltage of a capacitor 23, an ignitor 16 operates for a predetermined period of time, and a pilot burner of a burner unit 2 is ignited. A discharge circuit 21 is closed by the operation of the relay 22, and opening of the electromagnetic safety valve 1 is forcibly held by the discharge current of a capacitor 19. In a case where a battery is used as a power source 18 and the voltage is lowered less than a predetermined value, the relay 22 does not operate. Accordingly, then a predetermined value, the relay 22 does not operate. Accordingly, opening of the electromagnetic valve 1 is not forcibly held, and a raw gas is not emitted from the burner unit 2. In such a case, if the voltage of the power source 18 is made more than a predetermined value, an ignition sound which is relatively large due to the ignitor can be prevented.

IPC: B21K1/30
Filed: 1990-05-11
Abstract: PURPOSE:To reduce the reduction of area in a forming time and to reduce the forming load by pushing an annular billet having a stepped hole agreeing nearly to the outer peripheral surface of a mandrel into a die set and moving the mandrel downward so that the stepped part is not crushed. CONSTITUTION:The annular billet W having a hole agreeing nearly to the major diameter part 4b of the mandrel 4 is set to a die 2 to push in a punch 1. First, as the mandrel 4 is fixed, the billet W is upset to the annular billet W having a stepped hole agreeing to the outer peripheral surface of the mandrel 4. Then, as the mandrel 4 is moved downward so that the stepped part on the inner periphery of the billet W is not squeezed, an outer toothed cylinder part is extruded. The sectional area of the billet W in this extrusion is equal to a value which is obtained by subtracting the sectional area of the major diameter part 4b of the mandrel 4 from the area of the set hole 2a of the die 2, the reduction in area in the extruding time is reduced and the forming load can be diminished drastically.

Abstract: PURPOSE:To stop giving a driver unnecessary anxiety by preventing a charge warning lamp or an oil pressure warning lamp from coming on when engine rotating speed is in an unstable region or it is in an abruptly changing state even in a stable region. CONSTITUTION:With an engine set to an automatic start/stop control when the engine rotating speed sensed by a sensor 16 is in an unstable region and/or when it is in an abruptly changing state in a stable region, warning lamps such as a charge warning lamp Wc and/or an oil pressure warning lamp Wo are constituted so as not to come on even if they are supposed to be lit, if the voltage generated by an alternator 14 of a charging unit and/or the oil pressure in a lubricating unit becomes lower than the specified value to an oil pressure switch Ps. Accordingly, when the engine rotating speed is unstable caused by either stoppage of a starter after the completion of starting engine or stoppage of the  engine caused by failure in electrifying an ignition coil, the warning lamps are  kept from blinking so as not to give a driver anxiety.

Abstract: PURPOSE:To prevent the fluctuation of the introducing amount of a sample due to the clogging of a resistance pipe by introducing the sample into a buffer container held to final analytical pressure and dissolving the sample in a mobile phase to dilute the same to discharge the diluted sample to a separation column. CONSTITUTION:A sample is injected in a sampling valve 1 from the sample injection port 4 thereof and, at the same time, a mobile phase is supplied to a buffer container 3 from a mobile phase feed part 2. This mobile phase is injected in the container 3 in a supercritical state and a part thereof is discharged to the atmosphere through a resistance pipe 8 to hold the interior of the container 3 to final analytical pressure. After the sample is injected, when the valve 1 is revolved to connect a sample injection pipe to the feed part 2 and container 3, the sample flows in a metering pipe 7. Subsequently, when a flow path change-over valve 6 is changed over, the mobile phase from a mobile phase feed part 9 flows in the metering pipe 7 and the sample is sent out to a capillary column 10 to be separated in a supercritical state. By this method, a predetermined amount of the sample can be introduced without generating the clogging due to the precipitation of a solute.
