Title: Semiconductor storage device
Inventor: ABE KAZUHIDE
IPC: H01L27/108
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To reduce the area of a memory cell by forming a capacitor which has a perovskite type structure of dielectric film on the epitaxial regions made continuously in the direction of the line or row of a memory cell array, and making lower electrodes double as the plate electrodes of plural capacitors. SOLUTION: An oxide 21 such as MgO, or the like is epitaxially grown on an Si substrate 11, and a kind of noble metal of film such as Pt or the like is epitaxially grown as a lower electrode 22. Then, for example, a BaTiO3 film 23 is epitaxially grown as a perovskite type oxide on the lower electrode 22. Hereby, a highly reliable memory cell excellent in dielectric property of a capacitor and little in dispersion can be manufactured. Moreover, the lower electrode 22 can be epitaxially grown with good adhesion with the base. Then, since this is adopting a structure of forming plural capacitors in one epitaxial region, the area of a memory cell per bit can be made small.

The means 20 turns around a shaft 22 in an arrow direction 100 in the solder 11 from the one surface of the solder 11, thus separating and removing the copper component. The deposited copper component is captured uniformly if the scooping operation is repeated by a prescribed number according to the cooling stage of the solder 11.

Title: Air conditioner
Inventor: NAGAI MAKOTO
IPC: F24F13/22
Filed: 1986-02-19
Abstract: PURPOSE:To reduce the amount of remaining water at a drain port and decrease the degree of forming of ice by a method wherein a shape of an extremity end of drain port of an air conditioner is machine worked to have an irregular shape. CONSTITUTION:An irregular shape is applied in the direction of height of burring of a drain port 4 of an air conditioner, a certain volume of dew 2 is collected at the convex portion and then the dew is dropped by its own weight. An extremity end of a drain port 4 is made as a corrugated form, a minimum radius of curvature R1 of a recess portion and a minimum radius of curvature R2 of a projecting portion are applied to have a relation of R1>=R2. With this arrangement, an amount of remaining dew becomes quite low and an amount of iced water at an extremity end of the drain port is also decreased. With this arrangement, no trouble is found at each of the component elements during a period when a temperature of an air conditioner is increased up to a surrounding atmosphere temperature under which an operation of the air conditioner is assured and so an operation of the air conditioner can be continued.

Title: Hydraulic control device for power transmission device for vehicle
Inventor: ITO HIROSHI
IPC: F16H59/42
Filed: 1989-02-13
Abstract: PURPOSE:To prevent production of engagement shock at a frictional engaging device by a method wherein during a given period starting from selection of a running range, a signal pressure by means of which the back pressure of an accumulator is regulated is exerted on the valve stem of a pressure regulating valve, and during a time except the above, no signal pressure is applied. CONSTITUTION:When a signal pressure Psol4 from a signal pressure feed means 350 is not fed to a pressure regulating valve 170, an output oil pressure from the pressure regulating valve 170 is regulated to a specified value through the force of a spring 172, and a speed change control valve device 260 executes a switching work by means of an output oil pressure serving as a drive oil pressure. Meanwhile, during a given period starting from a time when a running range is selected, a signal pressure by means of which the back pressure of an accumulator 342 is regulated is exerted on a valve stem 171 of the pressure regulating valve 170 by a signal pressure feed means 350, and an output oil pressure is regulated based on the signal pressure. This constitution prevents production of an engagement shock at a frictional engaging device, and besides eliminates the need to independently mount a pressure regulating valve since a pressure is usually regulated as a drive oil pressure for the speed change control valve device by means of a pressure regulating valve to generate the back pressure of an accumulator.

Title: Compact electronic computer
Inventor: SHIBATA TAKAYUKI
IPC: G06F15/02
Filed: 1989-02-13
Abstract: PURPOSE:To quickly and clearly know the meaning of the memory contents and to easily call out the memory contents by displaying at one time the numerical value and the header showing the meaning of the numerical value in a pair and at the same time searching and reading out a memory from the first character of the head or the head itself. CONSTITUTION:The character data on the first character 'KI' of a header 'KINGAKU', for example, showing the meaning is inputted to the storage data of a RAM 15 via a KANA (Japanese syllabary) key. The character data on 'KI' is stored in an upper-stage display buffer 18a and then displayed at an upper-stage display part 19a. When a search key 115 is operated, a CPU 12 searches the inside of the RAM 15 and checks successively whether the first character of each data is coincident or not with the character data held by the buffer 18a. If the coincident character data is confirmed, the upper-/lower- stage storage data are read out of the RAM 15 and sent to the CPU 12. Then these storage data are written into the buffer 18a and a lower-stage display buffer 18b. In such a way, the meaning of the memory contents is displayed together with the numerical value and the memory contents can be easily called out.
