Title: Tunnel excavating machine
Inventor: UEHARA TOSHIAKI
IPC: E21C35/20
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To improve the taking-in efficiency of excavated soil by discharging soil taken into from the discharge opening of a soil-discharge plate after the soil has been scraped and collected to the center by a rotary cutter and a screw cutter. SOLUTION: Soil excavated by rotary cutters 10, 10 rotating oppositely to each other is raked up in between the rotary cutters 10, 10. Subsequently, the soil is collected to the center by flights 29 formed spirally opposite to each other from both ends to the central part in a screw cutter 27 of the rear side. Thereafter, the soil is pushed with advance of the excavator to the rear side soil-discharge plate 46 and discharged out of a discharge opening 50 formed in the soil-discharge plate 46 and positioned at the central rear part of the screw cutter 27. In this way, after the excavated soil has been raked up and collected to the central part by the rotary cutters 10, 10 and the screw cutter 27, it is taken in from the discharge opening 50 of the soil-discharge plate 46 and discharged.  Accordingly, the raking and collecting efficiency and the soil- discharge efficiency can be remarkably improved.

Title: Press die for transfer press
Inventor: YOSHINO ISAO
IPC: B21D37/10
Filed: 1990-06-07
Abstract: PURPOSE:To allow to set the guide post on the arbitrary position of the lower die and to improve the press working quality of the work by making the guide post to move up and down through the pusher pin and the intermediate component corresponding to the up and down movement of the upper die. CONSTITUTION:When the upper die 2 descends, the projection 16 contacts with the pusher pin 6 and pushes it down on the way of the above descent, so the guide post 5 is elevated through the link 9 corresponding to the descending movement of the pusher pin 6. When the upper die 2 descends further, the guide post 5 is inserted in the guide bush 15, the guide post 5 guides the upper die 2 while sliding in the guide bush 15, and finally, the prescribed press working is executed with the lower die 1 and the upper die 2 by reaching the upper die 2 to the lower dead point. When the upper die reaching the lower dead point starts again to elevate, the pusher pin 6 elevates gradually with the force of the elastic body 14 and by following this movement, the guide post 5 descends and returns to the original state.

Abstract: PROBLEM TO BE SOLVED: To nearly uniformalize distribution of a residual stress in the peripheral direction of a welded joint. SOLUTION: When the ends of tubes 1 and 2 whose outer faces are beveled are faced to each other and a weld joint is formed where the both tubes 1 and 2 are butted and connected by sequentially layering between beveled surfaces 1a and 1b a welded layer W composed of a weld bead 5 having the prescribed number of passes made by welding the full periphery where the part near an terminating end is overlapped with the part near a beginning end, the beginning end and the terminating end of the weld bead 5 are dislocated in the peripheral direction of the tube at each pass P1 through P13 to distribute the location of the terminating ends of the weld bead 5 where the residual stress is large, and further to relax the residual stress of the terminating end of the preceding layer of the weld bead 5 by the heat input from the welding of the next layer of the welding bead 5.  Further, the bead width near the terminating end of the weld bead 5 at the outermost face of a welded joint 6 is gradually decreased toward the terminating end, to decrease the residual stress of the weld bead 5 at the terminating end by suppressing the formation of a crater at the terminating end of the weld bead 5.

Title: Switching power device
Inventor: ARAI NAOKI
IPC: H02M3/335
Filed: 1989-06-15
Abstract: PURPOSE:To prevent a device from repeating its oscillation and stopping by providing an input voltage detection circuit to detect DC input voltage and to control the drive of switching elements moreover to provide its detection level with hysteresis characteristics. CONSTITUTION:When input voltage is low and a Zener diode IC1 is not turned ON, a transistor Q2 is OFF. When the input voltage is raised and the Zener diode IC1 is turned ON, the transistor Q2 is also turned ON and current I2 flows to the transistor Q2. On that account, even if the current I1 flowing through a resistance R1 is reduced at this rate, the Zener diode IC1 will keep on turning ON. In other words, even if the DC input voltage is reduced, the threshold value on the detection level will be reset to a low value.

Abstract: PURPOSE: To achieve hygienic enhancement by applying antibacterial treatment onto part or whole of an operating section operated by a player. CONSTITUTION: In a pachinko machine 1, antibacterial treatment is applied onto an operating lever 70, a handle cap, a base member, and a single ball shooting lever. The antibacterial treatment may also be applied to a ball supplying tray 6, a surplus ball receiving tray 8, ball game operating levers 13, 14, and a lens plate 81. A specific example of the antibacterial treatment may be referred to a process that such antibacterial metals as silver, copper and zinc are incorporated into zeolite in ionized condition, then, pulverized into fine particles, and kneaded into polymeric materials such as resin. Thus, such operating sections as a ball operating handle 60, a start lever and different switches are constructed by the polymeric materials (resin and the like).  Furthermore, a touch ring to detect a player's hands being touched from change in electrostatic capacity is constituted by an electrically conductive polymeric material, and fine zeolite particles into which metal ions are incorporated are kneaded into the polymeric material for applying the antibacterial treatment.

The initialization process is, therefore, speeded up and the formation of the intermediate value recording layer is made possible by the specified external magnetic field. The width of the striped magnetic domains forming the intermediate recording state is controlled by controlling the intensity of the laser beam for initialization.
