Title: Piezoelectric transformer and driving method therefor
Inventor: SAKAGUCHI TATSUO
IPC: H01L41/22
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To attain high transformer characteristics without causing any trouble in the vibration even when a transformer is being driven and without causing any deterioration at the joint of a lead wire and an electrode due to vibration by locating an output side electrode at the node of vibration. SOLUTION: Input electrodes 11, 12 of conductive material are provided on the upper and lower surfaces in the left half part of a piezoelectric long plate 1 and output electrodes 21 are located at a node of longitudinal vibration on the upper and lower surfaces in the right half part. The piezoelectric long plate 1 is polarized in the longitudinal direction from the input electrodes 11, 12 to the output electrodes 21 and in the direction of the thickness from the input electrode 12 to 11. When an AC voltage of resonance frequency is applied in a secondary mode in the longitudinal direction of the piezoelectric element between the input electrodes 11, 12, a longitudinal vibration takes place in the longitudinal direction. The longitudinal vibration propagates to a power generating section and a high output voltage appears at the power generating section, i.e., between the output electrodes 21 on the upper and lower surfaces in the right half part, in the piezoelectric longitudinal effect mode through an electromechanical coupling coefficient.

Filed: 1991-05-31
Abstract: PURPOSE:To reduce noise by placing a noise insulating tank outside a tank which houses the main contents of a reactor with a space left between for making the reactor multiple-structured and by filling the space with concrete and hardening it. CONSTITUTION:In a tank 1 of a reactor, the main contents, an iron core 2 and a coil 3, and insulating and cooling medium 4 such as insulating oil are stored. The main contents are placed in the tank 1 through cushioning material 5 such as vibrationproof rubber. A noise insulating tank 10 is placed outside the external side plate 1a and bottom plate 1b of the tank 1 with a proper space left between for making the reactor dual-structured. The noise insulating tank 10 and the tank 1 placed on the side of the main body of the reactor are united into one body with reinforcing material 11. The space between the tank 1 and the noise insulating tank 10 is filled tightly with concrete 12 and the concrete 12 is hardened. Vibration and noise which are generated by the iron core 2, etc., in the tank 1 try to spread outside through the tank 1. Due to the concrete layer 12, however, the vibration and noise are attenuated and are not carried outside.

IPC: H01S5/00
Filed: 1990-05-18
Abstract: PURPOSE: To make interlaced scanning unnecessary and simplify the structure of optical system, by making it possible to simultaneously write two adjacent scanning lines on an image bearing surface, by the offset of laser elements. CONSTITUTION: Active regions 16 which generate and transmit light waves in the state of laser operation are contained in a plurality of semiconductor layers formed on a substratum 12.

The regions 28 are formed to have a depth which can optically isolate laser elements 13A, 138 so as to evade the phase- locked state. Barriers 25A-25C are formed to stretch inside an array, and made adjacent to each other, while electric and thermal crosstalk to the independent operation of the elements 13A, 138 is restrained to a minimum. Isolated pumping contacts 22 and 24 are formed in order to make it possible to simultaneously write two adjacent scanning lines on an image bearing surface.  Thereby interlaced scanning is made unnecessary, and the structure of optical system can be simplified.
