Title: Control device for internal combustion engine equipped with variable valve mechanism
Inventor: YASUZAKI ICHIJI
IPC: F02D13/02
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine equipped with a variable valve mechanism, capable of controlling the amount of a valve overlap to a proper value matching a change in pressure within an exhaust pipe under any circumstances.

Title: Noodle making apparatus
Inventor: FUKAI KAZUO
IPC: A21C3/02
Filed: 1992-12-25
Abstract: PURPOSE:To provide a noodle making apparatus enhanced in noodle making rate per meal, designed to appropriately respond to the modes of operations concomitant with noodle making work such as flour dusting or encasing work each requiring manpower. CONSTITUTION:An operational panel 13 is provided with a key 18 capable of setting noodle making time intervals as desired to speed up the revolving rate of a mixer 4 or the feed of buckwheat flour 2 from a hopper 1, thus ensuring the feed interval for noodles 11 to be sufficiently long between 1st and 2nd meals even if noodle making time per meal is shortened, for example, from conventional 20sec to 15sec. Therefore, even though manpower shortage occurs temporarily because manpower for flour dusting or encasing work as an aftertreatment has been brought to other sections, when addressed by extending the noodle making time only during this period, there is no need for changing noodle making conditions per meal, enabling stable noodle making works at all times and avoiding unreasonable burdens on the above aftertreatment.
