Title: Dynamic type nonvolatile memory
Inventor: WADA TOSHIO
IPC: H01L29/792
Filed: 1978-05-12
Abstract: PURPOSE:To realize a high-density formation of IC for the nonvolatile MOS memory featuring the electric recovery property by using the nonvolatile MOS gate elements as the memory cells at th intersections of plural word lines and digit lines. CONSTITUTION:The nonvolatile MOS gate elements are used as the memory cells at the intersections of plural word lines and digit lines. The MOS gate element contains P-type Si substrate 201, high-density P-type region 203, N-type region 204 and floating gate 205 each with the capacity combination of the gate electrode and word line W as well as installation of lead-out electrode digit line D from region 204. With application of substrate electrode 209 and the positive voltage to word line W and digit line D respectively, the N-type inversion layer is formed right under the floating gate. On the contrary, if the voltage of about 10V and the voltage of over 15V are applied to line D and W each at the writing time, the high-energy electron is injected to gate 205 to increase the threshold voltage. Accordingly, if the potential of line W is kept at the +5V of line D at the reading time, the writing information keeps the nonvolatile property.

IPC: G11B5/60
Filed: 1986-03-14
Abstract: PURPOSE:To prevent a crosstalk caused by a leakage flux of a core, even if other part except an effective value travels on an adjacent track, by covering other part except the effective value of the core with a nonmagnetic material. CONSTITUTION:Other part except an effective area 12 of a core 1 is moved backward, and a space which has been formed therein is packed with a nonmagnetic material 23 such as glass, etc., by which a magnetic core which has exposed only the effective area of the core 1, and covered other part with the nonmagnetic material 23 such as glass, etc., can be formed. In this regard, it is also possible to constitute the magnetic head core so as to form integrally two pieces of constituting members 21, 22 and the part for covering other part except the effective area by using the same material, and to expose the effective area of the core from its window. As a result, even if other part except the effective area travels on the adjacent track, it does not occur that other information is written onto information of its track by a leakage flux of the core, and the cross-talk can be reduced.

Title: Mos digital space switch circuit
Inventor: YANO TAKAO
IPC: H04Q3/52
Filed: 1984-03-27
Abstract: PURPOSE:To reduce the power of a buffer by actuating only a necessary buffer in a selector. CONSTITUTION:Assuming that (0,0,0) is inputted as a control signal (a0, a1, a2), only a transfer gate of a gate I7 for inputting (0,0,0) is turned on because the outputs of three input NORs out of eight of transfer gates for inputting I0-I7 are connected to gates. As a result, buffers being operated in accordance with a signal of the gate I7 are only buffers A3, A5 and A6, whereas other buffers A0, A1, A2 and A4 are fixed to a high impedance output, that is, fixed to the value set by the operation at prestage because the prestage transfer gate is turned off. Accordingly useless electric power will not be consumed.

Abstract: PURPOSE:To keep grinding torque constant all the time as well as to make stock removal constant, by controlling a spindle head to be fed in the axial direction so as to keep rotational frequency of a rotating spindle constant as keeping a supply fluid flow rate to the rotating spindle constant. CONSTITUTION:An air flow rate Q1 to be fed to an air turbine 15 from an injection nozzle 16 is made constant whereby a rotating spindle 12 is rotated. At the time of noncontact between a grindwheel 11 and a work surface Wa, measuring revolution N1 of the rotating spindle 12 is equal to no-load revolution, so that the rotating spindle 12 is moved forward in a X direction solidly together with a housing 19, thus the grindstone 11 comes into contact with the work surface. And, the rotating spindle 12 is slidden to this housing 19 via a spring 10, and the grindstone is pressed to the work surface Wa. And, the housing 19 is moved in the Z direction till the measuring revolution N1 accords with the setting revolution N2. Therefore, pressing force F in the axial direction, namely, pressing force G in the normal direction becomes constant, whereby copy grinding takes place in this state, thus grinding torque can be made constant all the time.
