Title: Offset boring device
Inventor: ITO MASAMICHI
IPC: B23B43/02
Filed: 1990-02-20
Abstract: PURPOSE:To provide simultaneous machining with lathe turning for improved efficiency by rotating an opposing main spindle member provided with a rotary tool with an offset amount synchronously with the main spindle of this machine for offset boring during the rotation of the main spindle. CONSTITUTION:When the end cutting of a workpiece W held by a work spindle chuck 3 has been completed, outside diameter cutting is started by a cutting tool T1, and at the same time, a motor 8 is rotated by NC, and a waiting offset drilling unit 6 is moved to the main spindle 2 side through a ball screw 9 for positioning of the ends of drills T2, T3. Then an opposing main spindle 15 makes the output of a signal of a resolver coincide with the output signal which indicates the rotational angle of the work spindle 2 fed from the resolver installed on a headstock 1 for simultaneous rotation which coincides with phase and rotational speed with each other. By this simultaneous rotation, gears 23, 24 which are engaged with a fixed gear 27 at the end of the fixing shaft 26 are rotated, so that drilling is started by cutting feed to the main spindle 2 side of the offset drilling unit 6.

Title: Reset circuit
Inventor: NAGAO TOMOHIRO
IPC: H03K17/22
Filed: 1991-03-06
Abstract: PURPOSE:To prevent the occurrence of a malfunction of a digital circuit when a power supply is applied, i.e., to surely output the initialization state setting signal at an optional, level. CONSTITUTION:Two time constant circuits consisting of the resistances and capacities are inputted to the plus and minus sides of an amplifier 7 respectively. A difference is produced between a time constant receiving the substrate effect and a time constant receiving no substrate effect at each rise when a power supply is applied owing to application of the low density ion injection resistance with which a well is floated. Then the difference of time constants is detected by the amplifier 7. Thus one of time constant circuit can surely output a reset signal to a digital circuit.

Title: Heat plasma torch
Inventor: SHIBUYA YUKITO
IPC: B23K10/00
Filed: 1992-01-31
Abstract: PURPOSE:To prevent burnout of an O-ring for sealing a cooling liquid and generate hot plasma with a large electric by radiating the heat inside of an inner cylinder to the outside through a metal thin film. CONSTITUTION:A hot plasma torch 31 in single tube double system has a torch tube composed of an inner cylinder 1 and outer cylinder 3, which are made of ceramics with very high heat resistance, and a metal thin film 32 is provided over the whole circumference of the bottom periphery 1a of the inner cylinder 1, where an O-ring 9 is fitted for sealing a cooling liquid 7. Accordingly the O-ring 9 is fitted through a thin film 32. Joining the thin film 32 with the inner cylinder 1 may take place in any appropriate methode, and the film thickness is selected appropriately depending upon the torch 31 service conditions, the thermal conductivity and anti-corrosiveness of the film 32. Because the surface where the ring 9 is detained is the thin film 32 when this type of torch 31 is used, the ring 9 can be cooled effectively by the heat conduction of the thin film 32. The ring 9 is therefore prevented from burning out even though the inner cylinder 1 is heated by the hot plasma 2 to a high temp.

IPC: F01N13/04
Filed: 1984-03-02
Abstract: PURPOSE:To maintain the performance of purification for a long period of time, by providing a hollow monolithic catalyst whose periphery of cross section is shaped as a circle or the like, and by packing catalyst pellets in the hollow portion of the monolithic catalyst so that the velocity of exhaust gas flowing through the central portion of the catalyst and that of exhaust gas flowing through the peripheral portion of the catalyst are near each other. CONSTITUTION:A hollow monolithic catalyst 3 whose periphery of cross section is shaped as a circle or an ellipse is formed. Catalyst pellets 4 are packed in the hollow portion of the monolithic catalyst 3, so that a catalyst 5 for purifying exhaust gas is provided. After nets 6 for fixation are attached to both the end faces of the catalyst 5, the catalyst is fitted in a catalytic converter cas ing 7 so that a catalytic converter 8 is constructed. Since the catalyst pellets 4 whose resistance to exhaust is higher than the monolithic catalyst 3 are packed in the central portion of the catalyst 5, in which the flow rate of the exhaust gas is larger, the difference in the flow velocity of the exhaust gas between the central and the peripheral portion is decreased. For that reason, the entire catalyst 5 is uniformly used, so that the performance of purification is enhanced, and maintained for a long period of time.
