Title: Portable power supply vehicle
Inventor: KANEKO TSUGIO
IPC: F02B77/13
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To obtain a profound effect with a small space in a heat insulation property between an operating chamber and a load-carrying platform by arranging an intake port on a bottom part of an air chamber formed between heat insulating walls, and opening one end of an air duct whose other end communicates with an upper part of the air chamber in the air sending direction of a radiator fan. SOLUTION: In a portable power supply vehicle in which a power generator and an engine are arranged on a load-carrying platform 1c of a load-carrying chamber 1b, when power generation is carried out by driving an engine, a temperature in the load-carrying chamber 1b is raised. As a result, air in the air chamber 3 is heated through one heat resistance wall 2, and is delivered through an air duct 14. An opening of the air duct 14 is matched with the air sending direction of a radiator fan 6, and a delivery rate of air from the air duct 14 is increased by a draft effect. Air delivered from the air duct 14 is delivered from an exhaust port 10 through a radiator 7 and a space 9 by the radiator fan 6. New air is sucked from an intake port 13 into the air chamber 3, and temperature rise is suppressed.

Title: Teaching box
Inventor: NOSE HIDETAKA
IPC: G05B19/42
Filed: 1987-12-10
Abstract: PURPOSE:To easily handle a multi-functional teaching box by performing the robot teaching actions via an input means. CONSTITUTION:A teaching box 18 used for a welding robot 14, etc., is controlled by a CPU 72 and displays a main menu 104 on an LCD display screen 70 with application of a power supply.

Patent JP-H03170273-A (JP)
Title: Snap-ring inserting device
Inventor: TAKAYAMA KATSUTOSHI
IPC: B25B27/20
Filed: 1989-11-30
Abstract: PURPOSE:To prevent a snap ring from entering into the inner dia. of the collar of a washer on the way of an insertion process by providing the first pusher for pushing the washer, the second pusher for pushing the snap ring and an elastic member for protruding the end face of the first pusher, the wire dia. of the snap ring longer than the end face of the second pusher. CONSTITUTION:A washer 9 and an enlarged snap ring 10 are inserted from the end of an axis 4 and pushed forward in an axial direction by the first and the second pushers 21, 22. At this time, as the first pusher 21 is further protruded at the end face than the second pusher 22, the washer 9 always goes beyond the snap ring 10 in an insertion process. When reaching a preset position to stop the washer 9, the first pusher 21 no longer proceeds but the second pusher 22 further proceeds against elastic force of an elastic member 23 to push the snap ring 10 forward. The snap ring 10 thus reaches a groove 11 which is formed in the axis 4 and enters the groove with the dia. shrinked due to elastic restoring force for itself.

Title: Motor controller
Inventor: MATSUO KEISUKE
IPC: H02P29/00
Filed: 1992-11-24
Abstract: PURPOSE:To provide a motor controller for performing constant speed control through periodic feedback of FG signal in which fluctuation of rotational speed due to disturbance torque is suppressed greatly. CONSTITUTION:A period signal TFG of FG signal and a driving signal D for a driver 150 are fed to a disturbance estimating unit 1 which produces a disturbance estimation signal d1 representative of disturbance torque taud expressed in terms of driving signal. On the other hand, a comparator 130 compares the period signal TFG with a period command value Tr to produce a period error signal DELTATFG which is subjected to proportional-integration compensation by a controller 140 to produce a control signal (c). A correcting unit 10 adds the disturbance estimation signal d1 to the control signal (c) thus offsetting the effect of disturbance torque taud and producing a driving signal D. The driving signal D is fed to the driver 150 which then applies a driving current Ia to a motor 100.

Title: Method for managing magnetic attraction of print hammer
Inventor: FUJITAKE NORIYUKI
IPC: B41J2/30
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To adjust flexure of a leaf spring accurately by adjusting the initial flexure of the print hammer depending on the fact whether the print hammer is released or not at an arbitrary cancel current level thereby reducing excess magnetic attraction of the print hammer. SOLUTION: At the time of adjusting a hammer mechanism section 10, a leaf spring 4 is attracted and a lower limit cancel current is fed to a hammer coil 3. A print hammer 1 is then checked for projection and a next print hammer is checked if projection is not detected. If projection is detected, initial flexure is decreased by several μm and a lower limit cancel current is fed again. The procedure is repeated until projection of the print hammer 1 can not be detected any more. Subsequently, the hammer coil 3 is fed with an upper limit cancel current and checked for projection. Adjustment is ended if projection is detected, otherwise initial flexure is increased by several μm and the upper limit cancel current is fed again. The procedure is repeated several times until projection is detected again.

Title: Electromagnetic clutch and driving force transmission device using the clutch
Inventor: SAKAI NAOYUKI
IPC: F16D27/115
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To suppress fluctuations of the clutch characteristics of an electromagnetic clutch and prevent the generation of noise by decreasing the fluctuation width of a repetition fluctuation of a carried current during duty control of an energizing current to the electromagnetic coil of an electromagnetic clutch. SOLUTION: A copper ring 18 which is a nonmagnetic and high conductive member is disposed in the vicinity of the circulation magnetic circuit X of an electromagnetic clutch. By disposing the copper ring 18, a counter electromotive voltage due to a fluctuation of the number of magnetic fluxes is generated and a reverse direction current in a direction reverse to the current fluctuation of an electromagnetic coil is generated. The reverse current is operated to offset a fluctuation of an energizing current, resulting in reduction of the fluctuation width of the repeat fluctuation of the carried current, maintenance of the engaging force of the electromagnetic clutch in a state reduced in a fluctuation width, and reduction of the generation of noise due to the repeating fluctuations of the engaging force.
