Title: Mixed injection for cutting fluid and device thereof
Inventor: USUI TATSUO
IPC: B24C7/00
Filed: 1991-03-14
Abstract: PURPOSE:To enhance cutting force by flowing out abrasive grain and water in order to an outlet part side through an outflow passage around the end of a high-pressure water pipe to be mixed with a first high-pressure water, and force-feeding mixed cutting fluid to a liquid feed pipe for the uniform concentration distribution of a grinding wheel. CONSTITUTION:When high-pressure water is fed from a high-pressure pump 14 to a high-pressure pipe 15 under pressure, a negative region 18 is generated at an outflow passage formed at an outlet part 11a by high-pressure water jetted to a liquid feed pipe 16 side from an end jetting port 15b to pull surrounding abrasive grain 13 into the outlet part 11a side. Moreover, the high-pressure water jetted to an upper part 15a in a high-pressure tank 11 from the communicating part 15a of the high-pressure water pipe 15 pushes abrasive grain 13 mixed with water 12 to the outlet part 11a. Abrasive grain 13 is fed out in order to the negative region 18 side through the outflow passage, and is mixed with high-pressure water jetted from the end jetting port 15b of the high-pressure water pipe 15 at the outlet part 11a, and is agitated and mixed sufficiently until it has been fed out to the liquid feed pipe 16 as cutting fluid 19 by pressure feed force of high-pressure water and has been jetted.

Filed: 1991-03-14
Abstract: PURPOSE:To drastically decrease the internal strains accumulated in deposited metallic thin films by incorporating a metallic thin film forming stage using an electroless plating method in the process for production at the time of producing the very small machine element. CONSTITUTION:A resist 2 is applied on the surface of a substrate 1 (silicon substrate, etc.), is dried and is irradiated with light, by which the patterns 3 of the resist 2 are transferred. The resist 2 is then subjected to development in order to remove the unnecessary resist. After the resist patterns 3 are activated by an activating liquid, the substrate 1 is plated by an electroless plating liquid to form the metallic thin films 4 (Ni, Cu) of the thicknesses from several hundreds angstrom to several microns. The resist patterns 3 are then removed. As a result, the very small machine having the metallic thin films 4 drastically decreased in the accumulated internal stresses is obtd.

Title: Motor
Inventor: SETO TAKESHI
IPC: H02K15/02
Filed: 1990-03-23
Abstract: PURPOSE:To improve the cooling efficiency of a motor iron core by forming the shapes of steel plates of a laminated iron core so that the periphery may not be rotationally symmetrical about the angle of rotation during the turn lamination of lamination layers. CONSTITUTION:Odd steel plates 1 and even steel plates 2 are laminated alternately in specified numbers while being rotated 90 deg. at a time so as to form the iron core of a motor shown in the figure. Hereupon, though the odd steel plates 1 and the even steel 2 are the same in shape, they are rotationally symmetrical about 180 deg., but the peripheries are not rotationally symmetrical about 90 deg. in angle of turn lamination in this example, so the periphery of the iron core becomes fin-shaped at the time of lamination. Since the periphery of the iron core is fin-shaped this way, cooling wind takes away heat efficiently while circulating the iron core in circumferential direction. Moreover, some wind advances in the axial direction after hitting on the iron core, but at that time it causes turbulence by the fin part of the iron core, so cooling efficiency improves.

Title: Signal transmitter
Inventor: ANTONIO BURAIDAA
IPC: H04B3/02
Filed: 1980-06-03
Abstract: A signalling apparatus has at least one transmitter in a transmitter assembly for transmitting a signal by impressed current to several spatially separated receivers. A series circuit of threshold members is connected to the output terminals of each transmitter, the number of members corresponding to the number of receivers. The input of each receiver is connected to a threshold member; the receivers are therefore connected in series on the input side. It is ensured thereby that the same current flows through all receivers. In the event of a failure of a transmission line or a receiver, the current continues to flow through the associated threshold member so that signal transmission to the other receivers continues uninterrupted.

Then in the holding time, capacitor CA3 1  supplies the charge of the save value in the fixed times to capacitor CB1 and with every clock cycle τ=1/f c  (f c : clock frequency). On the other hand, capacitors CA3 2  and CA3 3  supply the same charge as that in the holding time to capacitor CB1 and every time τ in sequence in the non-holding time. Thus the same charge is always applied to capacitor CB1 via the discharge belonging to one sampling cycle.
