Abstract: PURPOSE:To form a minute base electrode simply, by providing an electrode on the uppermost layer of a multilayered structure, which forms a transistor, on a substrate, forming a side wall with a film, exposing the uppermost layer through resist, and removing the side wall. CONSTITUTION:A multilayered structure comprising a collector contact layer 2, a collector layer 3, a base layer 4, an emitter layer 5 and an emitter contact layer 6, which forms a transistor, is provided on a semiconductor substrate 1. The layers 5 and 6 are etched, and the uppermost layer is formed. An emitter electrode 19 is formed on the layer 6. The substrate 1 is covered with an SiO2 film 11. A side wall of SiO2 is formed on the uppermost layer by etching. Etching is performed by using resist 12, and the uppermost layer is exposed. The side wall is removed. With the uppermost layer and the resist 12 as masks, metal evaporation and the like are performed. Then, a minute electrode, whose width can be controlled in correspondence with the thickness of the film 11, is simply formed by self-alignment. Thus, the high integration density and high frequency of the transistor are attained.

Filed: 1981-02-02
Abstract: PURPOSE: To extract pure steam from steam in which air and other gas are mixed, by condensing the steam once to remove oxygenous component from the mixture, and then revoporizing the resultant condensed water.  
     CONSTITUTION: An ejector 3 is driven by steam generated in a boiler 1, so that steam from another generating source is sucked, recovered and supplied to condensed water in a gas-separating vessel 4.

Title: Production of spherical graphite cast iron
Inventor: YOSHIDA TOSHIKI
IPC: C21C1/10
Filed: 1995-01-31
Abstract: PURPOSE: To provide a process for producing a spherical graphite cast iron capable of preventing the chilling of the cast iron by sufficiently exhibiting its effect even near the surface of a casting mold without the generation of the inoculant remaining without melting. CONSTITUTION: This inoculant has the melting temp. lower than the melting temp. of the spherical graphite cast iron and is basically obtd. by using, for example, an Ni-Si alloy as the inoculant. The inoculant melts easily and rapidly in a casting process. While it takes time for the inoculation effect to be exhibited in the case where inoculant does not easily and rapidly melt, the inoculation effect is exhibited rapidly and, therefore, the generation of the inoculant remaining without melting does not arise even if the inoculant is added in the state of large size grains into the cast iron. The inoculant remaining without melting is lessened even if the inoculant is added into the casting mold.

Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of a badly-balanced optimization result depending upon the selection order of an object layer to be optimized by providing a delay restriction distribution part which distributes delay restrictions to respective layers and wires according to the possibility of optimization. SOLUTION: A logic circuit to be optimized is inputted from a hierarchical circuit specification input part 1 and stored in a circuit data base part 3. Then the delay restriction value of the object logic circuit to be optimized is added to a logic circuit depending upon the circuit data base part 3. Information, etc., for a timing analysis of respective blocks of a target library is inputted from a library input part 7 and stored in a library data base part 8. A timing analysis part 4 takes a timing analysis of the logic circuit stored in the circuit data base 3. Consequently, when the number of slacks of all paths is not negative, that means that there is no restriction breaking path and output is performed; and a delay restriction distribution part 5 distributes delay restrictions to paths extending between layers.

Title: Character-string input method
Inventor: TANAKA MITSUKO
IPC: G06F17/21
Filed: 1992-01-30
Abstract: PURPOSE:To set character size of an inputted character-string to a document memory by designated character size without depending on size of a cursor, with regard to an input of a character-string, in a Japanese language word processor. CONSTITUTION:Whether character size is set to designated character size or not is discriminated by a processing 5, whether a character is a specific character or not is discriminated by a processing 6, and if so, the character size is changed in reality by a processing 7, and in other case, the character is set by the character size being in a state that it remains size of a cursor to a document memory by a processing 8. It is repeated by the number of times of characters to be set to the document memory. A person who inputs a character-string can set simultaneously a character-string in which various character sizes are mixed without changing the size of the cursor. Also, when the character size is set to the specific character once, it can be executed repeatedly until it is released.

Title: Japanese character thermal transfer printer with switching function of emphasizing printing system
Inventor: TAKAHASHI KIYOSHI
IPC: B41J2/00
Filed: 1987-01-23
Abstract: PURPOSE:To realize a printed result, a processing speed and economy according to the demand by the user of a printer, by providing two kinds of emphasizing printing systems, and make it possible to switch to one of the two systems according to the data sent from a host device. CONSTITUTION:Two kinds of exphasizing printing systems can be selected according to the data sent from a host device. One method is based on a system for realizing emphasizing printing by a single printing operation, wherein an emphasized pattern is previously formed from a character patten for normal printing, and is printed. This method ensures that processing speed is not lowered, and consumption of an ink film is less, but a high-density character will be illegible. In another method, the same character is printed at a position in the first printing operation, and is printed at a fixed distance from the position in the second printing operation. In this system, high-density characters can be printed in a legible emphasized form, but there are the demerits of a lowering in processing speed, an increase in the consumption of the ink film and less difference between an unemphasized font and an emphasized font. Thus, the two emphasizing printing systems have respective merits and demerits. The two systems can be selected by the user of the printer according to the data sent from the host device.
