Title: Boosting signal generating circuit
Inventor: HIDA YOICHI
IPC: H03K5/02
Filed: 1989-04-12
Abstract: PURPOSE:To attain a smooth rising waveform of a word line driving signal and to improve the reading speed of the memory cell data by setting the voltage of the higher side of a complementary FET inverter circuit at a level higher than the power voltage. CONSTITUTION:When the power voltage is applied to a power terminal 30, the contacts 33 and 36 are charged by a charging FET 35 and a rectifying FET 34 respectively. Then both oscillation circuits work at one time to raise the voltage level. When the signal phiW0 of an input terminal 44 is equal to '0', the level of an output terminal 43 is raised up to '1'. At the same time, an FET 49 conducts to accelerate the rise of the level of an input terminal 50. Furthermore a MOS transistors 101 functions to prevent the current that is supplied to a power supply 48 due to the rising of the level of the terminal 43. As a result, the smooth rising is secured for the word line driving signal phiW and the reading speed is increased for a memory cell.

Title: Spline coupling
Inventor: KATSUTOSHI KAORU
IPC: F16D23/04
Filed: 1979-07-25
Abstract: PURPOSE: To prevent an axial movement of a spline upon transmitting a torque by a simple constitution wherein protuberances are provided on surfaces of teeth of the spline.  
     CONSTITUTION: A spline coupling for torque transmission is transmitting the torque by moving a gear 3 on the spline shaft 1 by an operation of a fork (not shown) to engage the gear 3 with a gear 6. In this case, forces shown by arrow signs C, D are acting between a gear surface 2a of the shaft 1 and a gear surface of the gear 3 in the spline. However, only a frictional force between the gear surface 2a and the gear surface of the gear 3 is acting as a resisting force against movements in directions shown by an arrow sign E or opposite E, therefore, the gear 3 can be moved to a position shown by the broken lines when an external force bigger than the frictional force described above is exerted. In order to prevent this movement, protuberances 5 are provided on the gear surfaces 2a of the spline of the spline shaft 1 near an intermediate position between meshing and nonmeshing positions of the gear 3 and the gear 6.

Title: P-channel mos semiconductor device
Inventor: KUMAGAI NAOKI
IPC: H01L29/78
Filed: 1989-04-13
Abstract: PURPOSE:To prevent a leakage current due to an inverting layer generated in a low impurity concentration layer exposed on the surface of a substrate and covered with an oxide film from increasing by forming a region in which acceptor impurity is diffused on the surface of a p-type layer in contact with the oxide film. CONSTITUTION:A region 17 in which acceptor impurity is diffused is formed on the surface of a p-type layer 3 in contact with an oxide film 6. Thus, even if the surface impurity concentration of the layer 3 is raised and positive charge exists in the film 3, an inverting layer is not formed on the surface. Accordingly, a leakage current flowing through the inverting layer is reduced. Since such a diffused layer is formed only on the surface, an electric field in a bulk is not strengthened, and no adverse influence is affected for avalanche breakdown at the time of turning OFF. Thus, an inversion due to the positive charge of the surface layer is prevented to increase a safely operating range.

Title: Water treating method
Inventor: ICHIKI KAZUYUKI
IPC: C02F1/42
Filed: 1980-07-11
Abstract: PURPOSE: To discriminate the deterioration of ion exchange resin easily without using an electric conductivity meter by passing water to be treated through a specifically treated anion exchange resin layer after a mixed floor consisting of cation exchange resin and anion exchange resin.  
     CONSTITUTION: Water to be treated is fed at 5W50°C to a package layer of a mixed floor consisting of cation exchange resin and anion exchange resin which are nearly equal in exchange capacity. Then, purified treating water is passed through cation exchange resin (1/10W1/100 as much as the cation exchange resin used for the mixed floor). In this case, when the resin of the mixed floor deteriorates, the pH of the treating water lowers to 2W3. Then, the treating water passed through cation exchange resin layer is passed through anion exchange resin layer containing an indicator (e.g., Thymol Blue) changing in color when it becomes neutral from acidic to detect the deterioration of the said mixed floor. Namely, when the ion exchange of the mixed-floor package layer exceeds its capacity, the deterioration of the resin is discriminated easily by the color change of the indicator.

Phosphorus ore is dissolved in the prepared diluted slurry at 50W95°C, and the resulting precipitates of phosphates of Fe, Al, and Mg and gypsium are separated and removed to recover the phosphorus component. The reason why the slurry is diluted to the concentration of phosphoric acid ≤30wt% is that an ion as much as possible of phosphoric acid attached to metal ions is separated from the metal ions.

Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To precisely detect a direction and a size of magnetization in an atomic level by detecting a tunnel current by a spin polarized electron supplied from a probe to a magnetization detective medium and obtaining the vertical and horizontal components of the magnetization. SOLUTION: A gap between the probe 21 and a sample (magnetization detective medium) 40 surface is adjusted, and while revolving a mirror 41 around an axis perpendicular to an incident plane of a support film 22 synchronized with a λ/4 plate 42, laser light is adjusted so as to be abutted on the probe 21. Then, when the laser light is made incident on the probe 21 from plural directions at a fixed incident angle, the spin polarized electron occurs in the probe 21. At this time, when a pulse voltage is applied between the probe 21 and the sample 40, though the spin polarized electron in the probe 21 is tunneled into the sample 40, the quantity are changed according to coincidence/noncoincidence between its spin direction and the magnetization direction of the sample 40.  Thus, the tunnel current is amplified by a preamplifier connected to the support film 22 to be sent to a computer, and the magnetization components of respective directions, and the direction and size of the magnetization synthesizing them are calculated.
