Title: Fluid discharge control method
Inventor: IKUSHIMA KAZUMASA
IPC: B05B17/06
Filed: 1996-01-12
Abstract: PURPOSE: To realize the non-contact between a fluid and the inner wall surface of a nozzle, to prevent the disadvantages such as corrosion, deterioration and wear of the inner wall surface of the nozzle due to contact and to highly control the discharged fluid. CONSTITUTION: A nozzle 1 for discharging a fluid 3 is vibrated to control the discharge of a fluid 3. Thus, vibration waves generated by vibrating the nozzle 1 propagate vibration waves specific to the discharged fluid 3 as synthesis of transverse waves and longitudinal waves thereof. At this time, by controlling the phase and the energy of the vibration waves, the discharged fluid 3 itself is variously controlled. For example, by the application and the phase control of ultrasonic vibration, a non-contact state between an inner wall surface 2 of the nozzle 1 and the fluid 3 is formed to prevent the disadvantages such as corrosion, deterioration, wear or the like due to the conventional contact between the inner wall surface 2 and the fluid 3. In case of fluid discharge, a liquid sagging phenomenon and clogging of the nozzle 1 in a nozzle discharge port part 4 are prevented.

Title: Magnetic disk device
Inventor: NISHIDA SADAHIRO
IPC: H02K33/18
Filed: 1986-01-16
Abstract: PURPOSE:To prevent the occurrence of an off-track phenomenon by forming a slit between the fastening leg parts of a coil bobbin and a carriage and therefore suppressing locally the deformation of the coil bobbin due to heat expansion. CONSTITUTION:A slit 19 is formed between the fastening leg parts 10a and 10c as well as 10b and 10d of a carriage 10 and a coil bobbin 16 respectively. In a seeking mode of an actuator, a current of a level several times as much as that of a standstill mode flows to a coil 17 and the bobbin 16 has a sudden rise of temperature. Thus the carriage 10 has deformation by heat expansion. This deformation is limited locally owing to the presence of the slit 19. Thus it is possible to prevent the occurrence of an off-track phenomenon without using any heat shield.

IPC: G08C25/02
Filed: 1984-01-13
Abstract: PURPOSE:To decide easily the end of the confirming transmission for checking of each slave device at the side of a master station by sending always the signal sent back from an artificial slave device to the master device through a repeater regardless of the state of the signal line at the slave device side. CONSTITUTION:The send-back signals RP of each slave device 2 and an artificial slave device 8 which are sent back from a repeater 4 are checked by a master device 1 in a multiplex transmission system connected with the device 1, devices 2, the repeater 4 and the device 8. The device 8 can receive directly the transmission output of the repeater 4 by the impedance of a resistance 12 at an input/output part of a slave device MODEM6 of the repeater 4 even though a signal line 3 is inapplicable due to a shirt circuit fault, etc. Thus the repeater 8 can transmit directly the signal RP to a reception circuit 6a of a repeater 4 via an OR gate 10a in response to the own calling. Therefore the repeater 4 combines the signal RP and the signal sent from the device 1 to the device 8 and sends these combined signals to the device 1. Then the device 1 decides the end of the confirming transmission.
