Abstract: PURPOSE:To redude an exciting voltage of a piezoelectric oscillating element to reduce a dielectric strength of parts for an electric circuit thereby planning miniaturization and cost down of the device by a method wherein two pieces of the piezoelectric oscillating elements for an ink jet head are attached closely in reverse polarities each other. CONSTITUTION:The piezoelectric oscillating elements 4a, 4b are attached to an ink jet head supporting plate 3 so as to pinch it and the pinched surfaces of the supporting plate are grounded while a voltage is impressed to the surfaces opposing to the pinched surfaces in such a manner that the voltage is impressed through an inverting circuit 5 and an amplifier 6a at the element 4a side and through an amplifier at the element 4b side. According to this method, a composite oscillating output of the piezoelectric oscillating elements 4a, 4b becomes two times of the outputs of respective piezoelectric oscillating elements, therefore, a half of the electric source voltage becomes enough to obtain the same oscillating output, consequently, a half of the dielectric strength of the electric parts consisting of each exciting circuit becomes enough to stand against the voltage. Accordingly, not only the inexpensive parts with a general-purpose property can be utilized but also  the miniaturization of the element and integration of the circuit become easy.

Title: All-round circulating article and machining method thereof, and rotary encoder and machining method thereof
Inventor: SAWADA KIYOSHI
IPC: G01D5/245
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To prevent effect of a cumulative drift error with the lapse of time from showing up between specific adjacent machined elements in the case of all-round circulating type machining. SOLUTION: In the case of machining a large number of code elements of a code plate of a rotary encoder, the whole periphery is divided in the N-number (N>3) of blocks including the nearly equal number of code elements, and block numbers of B1 to BN are imparted in order counter-clockwise (clockwise). Machining is performed alternately in order clockwise and counterclockwise around a block of an arrow mark number 1 (the first in machining order) such as arrow mark number 1 (B1) → arrow mark number 2 (BN) → arrow mark number 3 (B2) → arrow mark number 4 (BN-1) →...→ arrow mark number N-3 → arrow mark number N-2 → arrow mark number N-1 →arrow mark number N. As the machining order of code element units in the same block, only counterclockwise (clockwise) order can also be used, or counterclockwise and clockwise order can be combined.  Since the adjacent code elements prominently large in machining time difference do not exist, no effect of a cumulative drift error with the lapse of time shows up between the specific adjacent code elements.

Title: Generating apparatus for ozone
Inventor: USUI AKIRA
IPC: C01B13/10
Filed: 1980-12-02
Abstract: PURPOSE: To produce and supply clean ozone by installing an NOx removing apparatus in connection with a silent discharge system ozonize to remove only NOx from an ozonized gas contg. NOx.  
     CONSTITUTION: An ozonized gas contg. NOx is introduced into a scrubbing tower 34 using water as an NOx removing apparatus from the outlet 20 of an ozonizer 16 to remove the NOx, and the ozonized gas alone is supplied from the outlet 36. Most of the NOx is N 2 O 5  and has very high water solubility. On the other hand, ozone is dissolved in cooling water at 30°C only by about 0.40%, and since the ozonized gas is not 100% ozone, the effective value is further reduced, and the solubility of the ozonized gas is almost negligible. Accordingly, only the NOx can be removed.
