Title: Zoom lens equipped with vibration proofing correction optical system
Inventor: SATO SUSUMU
IPC: G02B15/16
Filed: 1993-03-13
Abstract: PURPOSE:To obtain the zoom lens which maintains high image formation performance and has a vibration proofing correcting lens group by constituting an optional lens group behind a 2nd lens group from an object side by using a front and a rear group, and allowing either one to move in orthogonal direction to the optical axis. CONSTITUTION:The zoom lens consists of a 1st lens group G1 which has positive refracting power, the 2nd lens group G2 which has positive refracting power, and a 3rd lens group 3 which has negative refracting power in order from the object side; when the power is varied from the wide-angle end to the telephoto end, the interval between the 1st lens group G1 and 2nd lens group G2 increases and the interval between the 2nd lens group G2 and 3rd lens group G3 decreases. Further, the vibration insulating correction lens group is constituted as the rear group G2F in the 2nd lens group G2 and enabled to move in the direction perpendicular to the optical axis. This optical system does not vary in the height of a projection light beam to the 3rd lens group so much, so the rear group G2F is a part which hardly relates to aberration variation due to zooming and used as the vibration insulating correction lens group.

Title: Overtone piezoelectric oscillator
Inventor: OTA HARUYOSHI
IPC: H03B5/32
Filed: 1990-03-28
Abstract: PURPOSE:To realize the inexpensive vibrator with small size and high reliability by allowing a sub resonance electrode to detect displacement of vibration so as to adjust the resonance frequency of the sub resonance electrode at an undesired harmonic resonance frequency from a main resonance electrode. CONSTITUTION:The frequency of electrodes 2, 3 of a main resonance electrode section is adjusted so as to be in resonance vibration at a desired harmonic resonance frequency. The vibration displacement is not detected from electrodes 4, 5 and 6, 7 of a sub resonance section at a frequency desired to be especially oscillated among harmonic resonance frequencies of the electrodes 2, 3 but detected at other undesired harmonic resonance frequencies and the frequency is adjusted by varying the thickness of a piezoelectric vibration substrate and the thickness of the electrode to control the oscillation. The frequency is adjusted by the independent resonance at the electrodes 4, 5 and 6, 7. Thus, an optional high-degree harmonic resonance frequency such as five-degree or over, not only a ternary overtone frequency is selected and utilized, the inexpensive vibrator with small size and high reliability is realized.

IPC: B60P1/02
Filed: 1987-03-30
Abstract: PURPOSE:To carry in and out cargo having a tall height which could not be carried in and out without using a noncovered wagon, by installing a suspension whose one edge can be lowered in and raised from a main frame and the other edge can be lowered in and raised from a supporting frame. CONSTITUTION:A main frame 1 is raised by an outrigger 19, and the upper surface of the main frame 1 is raised to the height nearly coinciding with the upper surface of a platform 21. A lifter table 7 is lowered by a hydraulic cylinder, and the upper surface of the lifter table 7 is allowed to coincide with the upper surface of the main frame 1. Since the rear edge of a leaf spring 3 is set free for a supporting frame 5, wheels 4 are left on a road surface in the cantilever attitude onto the leaf spring 3, and the interference between the lifter table 7 in lowering and the wheel 4 is eliminated. The cargo 22 having tall height is carried in through the lifter table 7 from the platform 21, and the cargo 23 having a relatively low height is loaded onto the lifter table 7, and can be carried in.

Filed: 1983-05-09
Abstract: PURPOSE:To correct the change rate of a cylinder speed or stop a device and to prevent generation of a product defect and accident by comparing the detected change rate and set change rate and judging abnormality. CONSTITUTION:The change rate of an injection cylinder 10 to be changed by adjusting the rate of the liquid supplied to or discharged from the cylinder 10 by a liquid flow control valve 29 is measured.
