Patent JP-S5510873-A (JP)
Title: Circuit for driving step motor
Inventor: OKANO MITSUTAKA
IPC: H02P8/00
Filed: 1978-07-08
Abstract: PURPOSE:To improve the frequency response of a step motor by utilizing the switching characteristics of a thyristor and the charging and discharging characteristics of a capacitor and applying high voltage to the step motor at starting time. CONSTITUTION:A main drive transistor 106 for energizing a two-phase excitation coil 103 is conducted by the output signal from a circuit block 101. Simultaneously, a thyristor 303 for applying high voltage to the coil 103 is conducted by the output gate signal from a circuit block 301. Thus, the second phase is excited by high voltage to increase the current exponetially. Then, the third phase is similarly excited. the thyristor 303 is reversely biased to be turned off by a capacitor 307 at the moment that high voltage is applied to the third phase excitation coil. Accordingly, when the low voltage power supply 119 is applied, the second phase excitation current is reduced, but the rotor is already rotated at this time. As a result, it does not need further current as the initial drive current due to the inertia to rotate as predetermined at an angle.

Title: Function trimming system
Inventor: MIYASHITA KAZUYOSHI
IPC: H05K1/16
Filed: 1982-05-20
Abstract: PURPOSE:To perform the desired characteristic test within a short period of stabilizing time for a circuit which ordinarily requires a longer time for stabilizing characteristic by executing a coarse adjustment until the characteristic value evaluation range is obtained and thereafter executing a fine adjustment to the same range. CONSTITUTION:A test measuring unit 4 performs characteristic value measurement by fetching a measuring signal from a module M through a probe unit 3 and outputs such data to a control processing unit 1. The unit 1 performs processing for such data, judges whether the coarse adjustment is completed or not. When it is not yet completed, it gives a trimming amount calculated by such data processing to the trimming unit 6, causing it to perform the required trimming (coarse adjustment). This trimming is repeated until an electrical characteristic of the object circuit reaches the specified value. If the characteristic value does not fall within the specified evaluation range within the evaluation time, the trimming (coarse adjustment) and measurement are repeated until it falls within the evaluation range. As explained above, the characteristic adjustment can be repeated for the object circuit without waiting for the stabilization time.

IPC: H01L29/78
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To perform element isolation without receiving any influence from a parasitic channel nor deteriorating the sub-threshold characteristic of element isolating areas by forming isolating grooves toward a strip heavily doped layer which is formed at a prescribed depth in a semiconductor substrate from the surface of the substrate so that the grooves may partially reach the doped layer. SOLUTION: A p<-> -type layer 4 which becomes a channel stopper area is formed in a p-type silicon substrate 1 carrying a thin oxide film 2 on its surface at a nearly fixed depth from the surface of the substrate 1 by implanting boron ions 3 into the substrate 1 over the entire area of the substrate 1 through the oxide film 2. Then an insulating layer 5 is removed from parts which become element isolating areas by etching the film 5 by using a photoresist layer 6 as a mask. After the insulating film 5 is patterned, groove sections 7 are formed at the parts which become the element isolating areas by using the patterned insulating film 5 as a mask. Therefore, the element isolating characteristic of the element isolating areas can be improved without deteriorating the sub- threshold characteristic of the areas even when the sizes of elements are reduced.
