Title: Network device setting method
Inventor: GASE STEPHEN T
IPC: H04L29/12
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To remotely operate/set network devices of one group with a single setting step. SOLUTION: In a network device setting method, a user selects a plurality of network devices where one or a plurality of parameters are to be changed from a device selection list. Then, a setting which is to be changed on the selected devices of one group is selected and a new setting value is inputted against the setting. It is repeated on the settings of a desired number. All the setting values on all the settings to be changed are inputted and the user starts a resetting sequence through an interface 21. A setting engine 25 sends a setting change to device which is selected first from the selected devices of one group, updates corresponding information in a data base 24 after the change completes and is recognized and sends the change to the next device in the selected devices of one group.

Title: Low pass filter
Inventor: OWADA SATORU
IPC: H01P1/203
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To ensure a high attenuation over a broad frequency band that includes frequencies higher than the cut-off frequency by providing each 2nd capacitive conductor that is projected in the middle of each high impedance line in a direction of the line and forms an electric field lower than that by each capacitive conductor with respect to a ground conductor. SOLUTION: The high impedance lines AH1 and AH4, and AH2 and AH3 respectively have the same length, and a metallic piece 11 (12) is placed in the middle of the high impedance line AH2 (AH3) in a direction of the line. Since the metallic piece 11 (12) is projected placed in the middle of the high impedance line AH2 (AH3) in a direction of the line to provide an electric field lower than that of capacitive conductors 5-7 with respect to the ground conductor 1 in this way, a signal with frequencies higher than the cut-off frequency fc decided on the bases of alternate arrangement of the high impedance lines AH1-AH4 and low impedance lines AL1-AL3 can be attenuated and then the low pass filter has an excellent attenuation characteristic over a wide frequency band.

Abstract: PURPOSE:To save manpower and to prevent erroneous operation, by providing a means for operating a sheet discharge direction switching means automatically based on a signal fed from a host machine and a motion means interlocked with switching operation of a sheet discharge stacker between containing position and using position. CONSTITUTION:Upon containing of a sheet discharge stacker 22 in a containing position (a) when a sheet discharge guide 20 is at the position (a), an arm 37 is pushed by a protrusion 22' to bring the guide 20 to a position (b) and held by a permanent magnet in a solenoid 34 (switching device) thus discharging the sheet in the direction B. The guide 20 can not move to a position for guiding the sheet to (a) side, i.e. the stacker side, because the arm 37 is restricted by the protrusion 22' even if a signal for moving the guide 20 to (a) side is provided to the solenoid 34 when the guide 20 is at the position (b). Consequently, jamming of sheet is prevented. When the stacker 22 is turned to use position, the arm 37 is released from the protrusion 22' and the guide 20 is displaced according to a signal fed from a host computer.

Title: Bush type vibration isolator
Inventor: ORIKAWA MICHIHIRO
IPC: F16F13/00
Filed: 1991-12-06
Abstract: PURPOSE:To improve durability of a bush type vibration isolator by suppressing excessive compressive deformation of an elastic body. CONSTITUTION:A disc-like stopper 22 is fixed at both of longitudinal ends of an inner cylinder 12 of a vibration 10 in which the inner cylinder 12 and an outer cylinder 14 are arranged in parallel. The stopper 22 is connected with an engine and does not contact an elastic body 16 in stationary state. (Refer to (A)). When the engine is oscillated up and down and large load acts on the vibration isolator 10 when vehicle runs on rough road and bumps, the elastic body 16, in particular, the section close to the inner cylinder 12 attempts to expand toward the outside in axial direction of the inner cylinder 12 (refer to (B)), but its expansion beyond the predetermined size is prevented due to its contact with the stopper 22. Namely, deformation (distortion) of the elastic body 16 is restricted. Since it is not deformed excessively, occurrence of crack of the elastic body 16 and its peeling from the inner cylinder 12 are prevented. and durability of the vibration isolator 10 is improved.

Abstract: PURPOSE:To simplify a memory circuit and a delay circuit greatly by adjusting the speed of each rotary polygon mirror driving means individually according to the phase difference of each light beam which is scanned by the rotary polygon mirror. CONSTITUTION:When a 1st beam detection pulse signal 75 and a 2nd beam detection pulse signal 76 are sent out of 1st and 2nd laser beam detectors 69 and 70 while having a phase difference T1, a timer means such as an internal counter circuit measures the phase difference of a rotary phase synchronism controller 2. Then one reference signal PSELECT obtained by selecting one of reference signals P1 - Pn with a selection switch 3 is sent out to a 2nd phase synchronism control part 5 as a reference signal for generating a phase close to the obtained phase difference T1. Consequently, 1st and 2nd motors 63 and 65 are brought under phase synchronism control of 1st and 2nd phase synchronism control parts 4 and 5 with the signal PSELECT for generating the phase difference, 1st and 2nd subsequent signals 75 and 76 are put almost in phase, and the beam reflecting surfaces of 1st and 2nd rotary polygon mirrors 64 and 66 are put in phase.

Title: Liquid fuel burning apparatus
Inventor: FUTAMI BUNKICHI
IPC: F23D5/04
Filed: 1988-12-23
Abstract: PURPOSE:To perform the complete combustion without disturbing the flame by disposing air inlets in the upper part of the burner shell to allow the secondary air blown by a fan to be supplied to the burning chamber. CONSTITUTION:An air inlet 28 is disposed in the upper part of both side plates of the burner shell 19. Because of this, the air 25 blown by a fan 18 enters from the air inlets 28 inside the burner shell 19 and descends along the front wall 19a of the burner shell to contact and mix with the flame 24. Since the secondary air 25 enters from the upper part of the sides of the burner shell and descends along the front wall 19a, it will not disturb the flame 24. Because the secondary air by means of the fan also enters from the upper part of the burner shell in addition to that which enters from the secondary air hole 20, the mixing ratio between the flame and secondary air assumes an appropriate value for complete combustion.
