Title: Zoom lens
Inventor: MIHARA SHINICHI
IPC: G02B15/167
Filed: 1990-02-02
Abstract: PURPOSE:To reduce the size and weight of the zoom lens by composing a 1st and a 4th group of <=3 lens elements, and satisfying specific conditions. CONSTITUTION:The 1st group and 4th group which have positive refracting power in order from the object side consist of <=3 lens elements which have small refracting power on the whole so as to compensate aberrations. In inequalities I - III, HFIIIIV is the front principal point of the composite system of the 3rd and 4th groups on the telephoto end, tIV is the overall thickness of the 4th group (distance from the surface closest to the object side to the surface closest to the image side), tI the overall thickness of the 1st group, and f2 and fr the focal lengths f the whole system at the wide-angle end and telephoto end. Consequently, the diameter and thickness of the 1st heaviest group decrease without any decrease in marginal light nor deterioration in image forming performance and the overall length becomes shorter, so that the size and weight are reduced as compared with a zoom lens with conventional specification.

Title: Air-fuel ratio controller for variable venturi type carbureter
Inventor: TERAMURA MITSUNORI
IPC: F02M7/16
Filed: 1982-02-17
Abstract: PURPOSE:To lower the low range of air fuel ratio by supplying air from an air bleed path into a bypass when the rotational frequency of an engine is higher  than a predetermined one in the decelerated running of a vehicle. CONSTITUTION:When the rotational frequency of an engine is higher than about 1,000rpm in the decelerated running, a solenoid 37 is energized to open a shut- off valve 35. Thus, air is supplied from air bleed paths 34, 26 into a bypass 28, and fuel flowing in the bypass 28 is reduced so that about 20-30% of total  supplied fuel amount in idling is continuously supplied from a nozzle 23. The engine is accelerated from such a condition, or fuel supplied into a cylinder is  immediately increased even when the running of the engine is shifted to idling.  Thus, the range of fuel reduction in the speed reduction range of running can  be lowered to about 1,000rpm.

Filed: 1979-03-01
Abstract: PURPOSE: To achieve the miniaturization of the electrode and improve its durability by coupling the electromagnetic coil comrising superposing plural isolated rings and insulation plates to the electrode base.  
     CONSTITUTION: An electrode O is opposed to the welded joint by leaving a slight spacing. When current is supplied from a feed bar 3, it flows to the other end U2 through the one end U1 of a ring conductive member 1a and flows to an electrode base 1 from the one end U1 of the respective ring conductive members 1b, 1c through the other end U2. At the same time, an arc is generated between the electrode O and joint and this arc is rotated along the electrode base 1 by the self- magnetic field produced by the current flowing through the electrode O. The magnetic flux of the magnetic field of this time is distributed in the radial direction by a magnet collecting case 10 and is formed as the driving magnetic field for driving the arc at a high speed, whereby the weld line is gradually heated and fusion bonded.
