IPC: H01L21/8242
Filed: 1990-09-28
Abstract: PURPOSE:To obtain a trench groove with a minuter diameter that has not been accomplished before, by oxidizing a holed silicon oxide film and a polycrystal silicon film on the side wall on the holed section of a polycrystal silicon film. CONSTITUTION:After a second polycrystal silicon film 8 is formed on a CVD- oxide film 6 and on a holed internal surface with CVD method, other parts are removed by etching back with RIE method, with a polycrystal silicon film 5 and the holed side wall section of the CVD-oxide film among the polycrystal silicon films 8 being left. The left part becomes a polycrystal silicon film 9. Then, the polycrystal silicon film 9 undergoes a wet-oxidation to be changed to a silicon oxide film 10. In this instance, a volume expansion occurs to expand the silicon oxide film 10 in a transversal direction, with the diameter of the hole being shrunk. Then, a silicon nitride film 4, a silicon oxide film 3 are etched with RIE method, etc., with the silicon oxide film 10 used as a mask. Finally, the exposed part within the holed section of a silicon substrate 1 is etched with the RIE method to form a hole 11 to be a trench groove within the substrate 1.

IPC: H02M3/155
Filed: 1985-11-18
Abstract: PURPOSE:To get the switching transistor to perform an efficient switching action and to reduce its driving power by impressing the trigger signal of the short pulse-duration from outside. CONSTITUTION:The trigger signal for switching on in a preset pulse duration is impressed to a driving transistor 3a for switching-on to switch it on. Through a driving transistor 5a the positive trigger signal is applied to a switching transistor 1 to make it an active region, and by its collector current the switching-on condition of the switching transistor 1 is maintained with a current feedback transformer 2. On the other hand, a driving transistor 3b for switching- off is switched on by the driving trigger signal for switching off, and through a driving transformer 5b a negative trigger is applied to the switching transistor 1 to reduce its collector current. The reduction of the collector current is positively fed back by the current feedback transformer 2 and the switching transistor 1 is then switched off.

Title: Method and apparatus for measuring sedimentation rate of red corpuscle
Inventor: SAITO TOMOO
IPC: G01N11/16
Filed: 1989-10-06
Abstract: PURPOSE:To measure the sedimentation rate of a blood corpuscle by detecting the oscillation frequencies of two quartz vibration sensors. CONSTITUTION:Quartz vibration sensors 1, 2 are arranged in a predetermined manner and a specimen is poured from an inlet 11 and discharged from an outlet. From the time immediately after the pour, the sensor 1 increases oscillation frequency as the apparent density and viscosity of the specimen reduce with the sedimentation of red corpuscles. The sensor 2 is reduced in its oscillation frequency by the increase of the apparent density and viscosity of the specimen on the surface thereof and the accumulation of the settled red corpuscle. The frequency changes of the sensors 1, 2 are respectively detected by counters 5, 6 and the difference therebetween can be calculated as the sedimentation rate of the red corpuscle according to a preliminarily calculated calibration curve. By this constitution, a sedimentation value corresponding to one hr can be accurately estimated within 5 min.
