Title: Semiconductor memory
Inventor: FUJITA YOSHIYUKI
IPC: G11C17/14
Filed: 1990-08-31
Abstract: PURPOSE:To prevent erroneous write of a memory cell by providing plural base current supplying means for impressing a base current to a writing current absorption transistor. CONSTITUTION:A buffer transistor 41-4m for setting a word line 11-1m at the prescribed current when writing in, a write means 20, a writing current absorption transistor 51-5m for absorbing the current of the word line 11-1m, a base current supplying means 61-6m which a program power source PVCE is impressed to through a common load 60 when writing in as well as impressing the base current to the writing current absorption transistor 51-5m when the word line 11-1m is set at the prescribed potential are provided. In such a case, when one word line is selected, the current flows through the load, and since the potential of the connecting point of the common load 60 and each base current supplying means 61-6m is lowered, even if little low level noise is generated in a non-selection word line, the writing current absorption transistor 51-5m does not absorb the current of the word line 11-1m. Thus, the erroneous write of the memory cell can be prevented.

Title: Formation of thin film component
Inventor: WADA TSUTOMU
IPC: H01L31/04
Filed: 1986-09-30
Abstract: PURPOSE:To prevent the damage generating on barium borosilicate glass by a method wherein, in the forming process of a thin film component having barium borosilicate glass as a substrate, phosphoric acid or phosphate of 0.03-5 mol/l is contained in an acid treatment solution. CONSTITUTION:Phosphoric acid itself or any phosphate can be used as the supply source of phosphate ions to be added to an acid treatment solution. Judging from the view point of the manufacture of thin film components, it is desirable that the chemical additive is added in the form of phosphate or phosphate of ammonia which does not contain alukaline ions and have excellent purity and high degree of solubility. Also, the optimum concentration of phosphate radical is 0.03-5 mol/l. This concentration varies by the temperature of treatment solution, and the concentration of 0.03 mol/l or less is insufficient when the concentration of acid radical is high, and also the degree of non- uniformity is high. Besides, in the case of concentration of 5 mol/l or above, the effect of phosphate radical is increased, but the viscosity of the acid treatment solution is increased, and the function of etching or the intrinsic function of pickling is lowered.

After an aluminum film is coated on all the surface by vacuum deposition, an aluminum wiring layer 18 is formed by patterning. Accordingly, aluminum is not penetrated and the contact resistance between the diffusion layer 13 and the wiring layer 18 is made lower.

Filed: 1984-11-05
Abstract: PURPOSE:To make steering wheel load adjustable so smoothly according to a car speed, by installing a hydraulic reaction mechanism, controlling movements of a spool valve, in position between a hydraulic pressure source for hydraulic reaction use installed separately and a variable throttle valve, varying its opening area according to the car speed. CONSTITUTION:In time do driving at low speed, this slow running is detected by a sensor 53, operating a solenoid 51a with this detected signal, and a throttle of a variable throttle valve 51b, increasing the discharge of a hydraulic fluid to some extent. And, since differential pressure being produced between the throttle valve and a hydraulic source P2 for hydraulic reaction use comes small, pressure of a hydraulic fluid out of a branch passage 52 also comes small, thus pressure inside both reaction chambers 31 and 32 comes down. Here, when a stub shaft 29 is rotated with a steering wheel 43, at first a sector shaft receives grounding resistance of front and rear wheels whereby a piston and a worm shaft 8 both are immovable and, what is more, there is produced relative turning displacement between these shafts 8 and 29. Therefore, when a pin 30b is rotated, either of pistons 23 and 24 moves to the right or the left, and a spool valve 12 is slidingly moved by a pin 30a, whereby the hydraulic fluid is fed or drained to or from a space between both operating chambers 3 and 4 so that steerage is assisted a steering wheel is nimbly steerable.
