Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To reduce slide resistance of a slide piece in a crossing part of a reciprocating spiral groove formed in a guide shaft body and to induce the slide piece smoothly in a product pushing-out device. SOLUTION: Linear parts 35b are formed on both sides in the longitudinal direction in a slide piece 35 to be assembled on a pusher travelling body reciprocating and travelling along a lead screw in a condition of engaged with a reciprocating spiral groove of the lead screw. A length L of the linear part 35b is larger than a groove width in a crossing part of two spiral grooves constituting the reciprocating spiral groove. For this reason, in a process in which the slide piece 35 passes the crossing part in which a wall face disappears, the linear part 35b is guided to a wall face of the groove on a front side to keep the slide piece 35 at the attitude in which it is along the groove direction until the linear part 35b is guided to a wall face of the groove at arrival destination.

Title: Method for feeding glass raw material
Inventor: ASANO OSAMU
IPC: C03B3/00
Filed: 1990-03-01
Abstract: PURPOSE:To stabilize the melting operation of glass by nonuniformly supplying a glass raw material in place of feeding uniformly over the whole surface in a smelting furnace, thereby locally forming a thin part of glass layer thinner than a specific thickness. CONSTITUTION:A glass raw material is locally supplied from a horizontally movable raw material feeding apparatus 2 to a smelting tank 3 of an electric melting furnace shown in Fig.I to form a raw material layer 4 having swollen part and recess on the surface of molten glass 6. The glass raw material is heated with an electrode 1 and the produced molten glass 6 is introduced into a working tank 5. Cracks are generated as shown in Fig.II by thinning the thickness of the recess part of the raw material layer 4 to <=300mm to facilitate the release of gas. Accordingly, the gas 8 in the semi-molten layer 7 formed between the raw material layer 4 and the molten glass 6 is continuously released through the cracks to enable the stable melting of glass.

Title: Ink-jet head
Inventor: HORIIE MASANORI
IPC: B41J2/16
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To ensure stabilized head characteristics while reducing manufacturing cost by employing an actuator means comprising a laminate of a drive layer of electromechanical conversion material being applied with a voltage and a nondrive layer of electromechanical conversion material being applied with no voltage. SOLUTION: Since a nondrive layer functions simply as a diaphragm, an actuator means 5 is deformed to project toward the pressure liquid chamber 2 side when a drive voltage is applied to a piezoelectric element constituting the actuator means 5 and ink in the chamber 2 is pressurized. Consequently, an ink drop is ejected from a nozzle communicating with the chamber 2. Since the actuator means 5 comprising a laminate of a drive layer of electromechanical conversion material being applied with a voltage and a nondrive layer of electromechanical conversion material being applied with no voltage, the nondrive layer can serve as a diaphragm and rigidity can be balanced easily. An efficient actuator can thereby be obtained and an ink drop can be ejected stably.

Title: Missile guiding system
Inventor: OKADA TORU
IPC: G01S13/68
Filed: 1993-03-11
Abstract: PURPOSE:To obtain a light-weight missile in which a shooting range can be increased by switching a corner reflector each time a guide command signal from a ground radar is received by the missile to vary a radar effective reflecting area of the missile. CONSTITUTION:When a guide command signal is sent from a radar, it is received by a reception antenna 8, and the signal is sent to an automatic pilot 12 through a receiver 9. Steering wings 16 are moved by a steering unit 15 to guide a missile. In this case, a reception signal for indicating that, when the signal is passed through the receiver, it is received by the missile is sent to a corner reflector controller 10 to switch a corner reflector 10, thereby varying a radar effective reflecting area of the missile. Thus, a transmitter for transmitting a reception confirmation signal to the missile is eliminated. Since the mass of the transmitter is increased in a missile system having a long shooting range, reduction in weight of the missile can be realized.

When the solenoid 86 is turned off, the pawl part 84a of the lever 84 is engaged with one of projections 83 so as to lock the rack 80. When the solenoid 86 is turned on, the engagement of the lever 86 with respect to the projection is released.  At this time, a current value flowing to the solenoid 86 is monitored and timing that the solenoid 86 is perfectly turned on is detected. Based on the turning-on timing, the rotation driving motor 82 of the rack 80 is started.

Abstract: PURPOSE:To impart superior characteristics as a magnetic tape of long length used in magnetic sound and video recording by directing non-magnetic layer vapor flow to a base material and at the same instant striking electrons against the same at the forming of the non-magnetic layer separating a ferromagnetic layer. CONSTITUTION:In a vacuum vessel 9 which is maintained of a vacuum atmosphere by an exhaust system 19, a high molecular molding base material 16 moves along the peripheral side face of a cooling can 10 from a let-off shaft 21 and is taken up on a take-up shaft 20 via roller 22. The non-magnetic material 11 in a water cooled copper hearth 12 is heated by an electron gun 13 and the vapor flow 23 thereof is directed to the base material 16 on the can 10 between deposition preventing plates 17. At this time, a potential is applied to an acceleration electrode 14 such as of metal screen of stainless steel disposed between the base material 16 and material 11 from a power source 15 via insulation lead-in terminal 18, whereby electrons are striken to the vapor flow 23 and a part thereof becomes of plasma state.
