Title: Controller for modulating pulse width of inverter
Inventor: YAMAI HIROYUKI
IPC: H02M7/48
Filed: 1990-01-09
Abstract: PURPOSE:To decrease error voltage by controlling ON/OFF of corresponding each phase switching element in a scheduled order. CONSTITUTION:The width of each pulse of selected voltage vector is scheduled in every control cycle, and according to this schedule, the on-off control of each phase switching element Tra-Trc and Tra'-Trc' is performed. In this case, it is scheduled in such order as the one long in pulse width being positioned at the first place of the control cycle, so within that schedule there is no necessity of changing the condition of the pulse, and the first pulse can be output accurately. Moreover, even if the next pulse to be output after the output of the first pulse width is short in pulse width, it is after completion of the schedule of the pulse width, so this short pulse can be output accurately.

Title: Container for cyanoacrylate adhesive
Inventor: ITO TOSHIHIRO
IPC: B65D41/17
Filed: 1990-01-09
Abstract: PURPOSE:To make a container safe for infants and the like by a locking mechanism whereby, in fastening an outer cap to main body of the container, projections at four points on a cylindrical part, provided at the shoulder of a square pillar-shaped container, are brought in contact engagement with fastening projections provided inside a square pillar-shaped outer cap and the outer cap is released from the main body of the container by elastically deforming and turning the outer cap. CONSTITUTION:Fastening projections 11 on an outer cap are placed under and in contact with ledges 10 on the main body of a container and the tips of the fastening projections 11 are in contact with the main body of the container so that they permit turning shifts, but since fastening struts 13 on the outer cap are engaged with projections 12 on the main body of the container, the outer cap is completely immovable. To release the outer cap from the engagement, the outer cap is held with two opposite corners, where the outer cap has no fastening struts, between fingers and pressed a little hard from the outside; then the outer cap is slightly deformed to assume a lozenge and then the fastening struts 13 withdraw from the engagement with the projections 12; the outer cap in that state is turned 45 degrees to the right or to the left and lifted softly. To put the outer cap in place, the outer cap is pushed down to the shoulder softly at the position after the turn by 45 degrees; the outer cap is pressed from the outside at the corners where the outer cap has no fastening struts, and, after withdrawal of the fastening struts 13, turned. While no vertical movement is allowed, the projections 12 stop the fastening struts 13 from being turned; thus the outer cap is held immovable. Thus a safe container whose cap can not be readily released even when it is in the hands of an infant or the like is obtainable.

Title: Device for controlling fuel injection of diesel engine
Inventor: AOYAMA SHUNICHI
IPC: F02B3/06
Filed: 1989-01-10
Abstract: PURPOSE:To miniaturize a solenoid valve and reduce power consumption while improve durability by making the solenoid valve act as a pilot valve for opening a back pressure chamber to open a plunger chamber via a spill valve at the time of stopping fuel injection. CONSTITUTION:As an exciting current to a solenoid valve 26 is cut off at a timing in line with an engine operating condition by a control circuit, a valve body 33 is moved to an open position by means of a spring 34 to open a second return passage 25. At this time, since a back pressure chamber 22 is disconnected from a plunger chamber 12 because of a pressure opening/closing valve 28, the pressure in the back pressure chamber 22 is suddenly reduced and a spill valve 19 is pressed by the pressure of the plunger chamber 12 and opened at a stroke against a spring 24, causing fuel to flow into a feed pump chamber 5 side out of the plunger chamber 12 to stop fuel injection. Thus, at the time of stopping fuel injection, the pressure in the plunger chamber 12 can be suddenly reduced by opening the spill valve 19 through the solenoid valve 26, enabling the momentary stoppage of fuel injection from an injection valve into an engine combustion chamber.
