Title: Drive circuit of step motor
Inventor: TSUKAHARA AKIHIKO
IPC: H02P8/14
Filed: 1983-09-21
Abstract: PURPOSE:To stabilize a step motor without stepout in both normal and reverse rotations at the restarting time of the stopping time. CONSTITUTION:The output C of a normal/reverse rotation timing generator and the output of a distributor 1 are logically applied to an AND gate. phi1, phi2, phi3, phi4 are excitation signals of step motor coils. When a step motor stops rotating and further rotates reversely, the motor is set to non-excited state after the rotor is advanced by 1/2 step angle in a rotating direction before becoming non- excited state, and a stepout is prevented by restarting the motor by resetting the excited state before becoming the non-excited state due to the elimination of a drive command pulse by a timing pulse from a normal/reverse timing pulse generator 3 at the next restarting time.

Title: Rotary hydraulic machine
Inventor: MORII SHIGEKI
IPC: F04D29/16
Filed: 1984-08-22
Abstract: PURPOSE:To prevent a rotor from being vibrated by providing a passage which induces fluid having static pressure boosted inside a diffuser into a spacing defined between an impeller and a casing surrounding it in such direction that the circumferential flow speed of fluid in the diffuser is reduced. CONSTITUTION:Gas which is discharged from the outlet 35 of an impeller 3 flows into a fiffuser 5, in which dynamic pressure is converted to static pressure. A part of gas having static pressure boosted in the diffuser 5 passes through fluid passages 12 and 14 which open to casing faces 25 and 26 and then flows into spacing 8 and 10 defined between the impeller 3 and the casing 2 which surrounds the impeller 3 in the centripetal direction as shown by the arrow directions 13 and 15. Since fluid inside the spacing 8 and 10 scarecely has circumferential speed, the fluid makes virtually free swirl and therefore flows into labyrinth seals 6 and 7 at a reduced flow speed of the circumferential direction. Exciting force produced in the labyrinth seals 6 and 7 will then be reduced remarkably so that vibration of rotor can be prevented.

Title: Fabrication of fine structure
Inventor: BABA TOSHIO
IPC: H01L21/324
Filed: 1993-07-14
Abstract: PURPOSE:To provide a method for fabricating a fine structure selectively on the surface of a crystal substrate. CONSTITUTION:Ions 2 are implanted selectively at high concentration into the surface of a crystal substrate 1 which is then heat treated to make a groove in the surface and the groove is selectively filled with a crystal 3 to fabricate a fine structure. When ions are implanted selectively at high concentration into the crystal substrate, the bond of crystal is released in the region implanted with ions and an amorphous layer is formed. When the substrate is heat treated appropriately, the amorphous layer is recovered to a crystal but since the released atoms has high mobility and the crystallization proceeds from the peripheral part of the amorphous layer, the ion implanted region finally sinks to form a groove structure having slightly protruding ridges. When a crystal is grown on such groove structure by MOCVD, for example, the groove is filled with a new crystal and thereby a fine structure can be fabricated easily.
