Patent JP-H11146638-A (JP)
Title: Power conversion device
Inventor: YAMAMOTO YASUHIRO
IPC: H02M3/155
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To make good use of the inductor of a commutating circuit for noise reduction to improve current balance between parallel elements. SOLUTION: A commutating circuit for noise reduction having inductors L1a-L1d, L4a-L4d comprising a capacitor C, an inductor L and a diode D, respectively, and series connected with a plurality of parallel switching elements S1a-S1b, S4a-S4d constituting the switches of upper and lower arms is connected with the elements. The inductors L1a-L1d and the inductors L4a-L4d are magnetically coupled using a core, respectively, to form an interphase reactor. The elements of the upper and lower arms are alternately turned on with a short circuit preventing period in between. Due to the magnetic coupling of the interphase reactor, a current through the parallel connected elements acts so that, if currents vary, all the currents become equal. Therefore, the current balance between the elements is improved.  Commutation, reflux or the like occurs in the commutating circuit when the elements are turned on/off, and it is passed through any diode without exception. The diodes have non-linear characteristics to the magnitude of currents, and thus noise is reduced.

Title: Formation of valve chamber in cylinder member for liquid ejector
Inventor: GOTO TAKAYUKI
IPC: B29D23/00
Filed: 1989-11-21
Abstract: PURPOSE:To prevent the increasing of the number of parts by a method wherein recess parts having the same shape as thick edges are formed by thrusting the several thick edges of V-shaped cross section spaced nearly equally and extending vertically downwardly from the outer peripheral part of the lower end face of a rod inserted into a cylinder member. CONSTITUTION:A cylinder member 1a is formed. After a ball valve 10 is placed into a valve chamber 7, a rod 21 having several thick edges 20 of V-shaped cross section spaced nearly equally and extending vertically downwardly from the outer peripheral part of its lower end face is inserted into the aforesaid cylindrical member. The thick edges are thrust into a stepped part 11 facing upwardly from above, whereby the recess parts 12 having the same shape as the thick edge are formed in the upper face of the stepped part. The peripheral wall of the valve chamber is partially forced apart from and inwardly of the upper part thereof to form an overhang 9. The overhang 9 is forced apart to such extent as not to allow its return to the original shape when the thick edge is removed. This ensures a proper operation of a mechanism for preventing the detachment of the ball valve.

IPC: F16H61/18
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To set the optimum gear ratio at the start from the stop of a vehicle in the control for at least partially automated mechanical transmission. SOLUTION: Input signals from an engine speed sensor 11, an input shaft speed sensor 98, an output shaft speed sensor 100 and a driver control console 210 or the like are processed according to designated logic rule by an ECU 106, and a command output signal is sent to a solenoid manifold 112 to shift a transmission 10 to a desired gear ratio. The ECU 106 uses the highest gear ratio (fourth speed) among a designated lowest gear ratio group (first to fourth speed) suitable for start-from-stop operation as a start ratio. By a driver's down-shift and up-shift operation, the start ratio is shifted to a lower gear ratio or a higher gear ratio. According to the status of a vehicle, the optimum start ratio can be obtained.

At the same time, an ink module 19 is operated, and it attaches printing ink on the recording area of the postal charge meter module 15, and retracts to a first position before the envelope arrives. When the conveyor roller 57 retracts, a weighing module 13 weighs the envelope, and informs a meter of meter setting. At the same time as a platen module 21 executes the printing of the stamp on the envelope in succession to metering, the conveyor module 12 is energized again, and returns the roller 57 to its first position. When the roller 57 reaches the first position, the envelope is discharged out of the mail machine.  Thus, the throughput can be increased remarkably.
