Title: Leakage detection circuit
Inventor: OKAMOTO TAKESHI
IPC: H02H3/33
Filed: 1978-05-10
Abstract: PURPOSE: To minimize the temperature dependence of the characteristic of the circuit by compensating for the change in the gate trigger voltage of a N-gate SCR by the Zener voltage of a Zener diode with a corresponding negative temperrature characteristic thereto.  
     CONSTITUTION: A zero phase current transformer 31 is connected to the joint of resistors 21 and 22 at one end thereof and connected to the gate of a N-gate SCR 11 at the other. In addition, the anode of the SCR 11 is connected to the joint of a resistor 23 and a Zener dode 12 with a negative temperature characteristic and the cathode thereof connected to a relay coil 32. In operation, when a current leakage occurs, a voltage is applied to the gate of the SCR 11 to actuate the coil 32. Herein, the anode potential VZD of the SCR 11 drops with increasing ambient temperarure, while the gate trigger voltage thereof drops at the same voltage gradiant as VZD. In this manner, the circuit is little affected by the rise in temperature, thus ensuring an accurate operation.

Title: Magnetic disk
Inventor: HIBINO SATOSHI
IPC: G11B5/73
Filed: 1986-03-13
Abstract: PURPOSE:To obtain substantial wear resistance and corrosion resistance by providing a silica layer and carbon layer on a magnetic layer formed on a substrate. CONSTITUTION:The substrate 1 provided with the magnetic layer 2 is subjected to a prescribed surface cleaning treatment and is housed in a chamber of a sputtering device. High-frequency sputtering is then executed with silica, synthetic quartz, etc. as a target to deposit the silica layer 3 of a prescribed thickness on the magnetic layer 2 on the substrate 1. The target is then exchanged with graphite and the sputtering is successively executed without taking the substrate 1 out of the chamber to deposit the carbon layer 4 having graphite crystal structure on the silica layer 3. Since the silica and carbon are continuously sputtered within the same chamber in the above-mentioned manner, the thin film consisting of the mixture composed of the silica and carbon is formed at the boundary face with the silica layer 3 and the carbon layer 4, by which the adhesiveness between the silica layer 3 and the carbon layer 4 is improved.

Title: Output buffer circuit of semiconductor element
Inventor: YASUDA YOUJI
IPC: G11C11/409
Filed: 1983-03-31
Abstract: PURPOSE:To attain the speed-up of an output buffer circuit by giving a reverse pulse signal to a gate of a PMOS transistor (TR) between the output and the power supply and an NMOS TR between the output and ground when an address signal is changed. CONSTITUTION:The NMOS TRQ3 conducting its output to the power supply VDD and the PMOS TRQ4 conducting its output to ground VSS are provided in parallel with an output buffer TR comprising a load TRQ1 and a drive TRQ2. A transition detector circuit TD detects the change in the address input signal so as to give a detecting signal having a prescribed pulse width to a gate of the TRQ3 and to a gate of the TRQ4 via an inverter INV1. Since the output level is brought into the intermediate level until the signal of the output buffer signal is changed after the address input signal is changed, the high speed operation is attained.

Filed: 1981-04-14
Abstract: PURPOSE:To reduce frictional resistance so as to transfer a highly condensed pulp liquid smoothly, by providing a gas supplying section at a bent section of a piping so that the pulp liquid may flow in a state supported by the supplied gas. CONSTITUTION:In the piping 5 for transferring a highly condensed pulp solution or the like, a steam supplying apparatus 6 is arranged in such a manner that a steam layer 12 is formed along the inner circumferential surface of an arcuate section 5b of a bent pipe section such as an elbow section, and a steam is sent out from a steam diffusing box 7 adjacent to the apparatus 6 via a rubber plate 9 and a porous plate 10 to form a steam layer on the inner surface of the pipe. Thus, as the solution would not strike directly the inner wall surface, and the friction is reduced, even the highly condensed liquid can flow readily. Alternatively, in addition to a steam, air can be used to obtain the same effect.
