Title: Pitch information processing device for code recognition
Inventor: TAKENAKA YASUHIRO
IPC: G10H1/38
Filed: 1995-04-14
Abstract: PURPOSE: To reduce the time required to conduct a code recognition process based on the inputted pitch information by conducting the code recognition using the pitch information of a note.on transmitted from a pitch information selecting means. CONSTITUTION: When pitch information is inputted by an inputting means 11, a pitch information selecting means 12 selects the note.on pitch information among the inputted pitch information so that the note.on pitch information becomes a prescribed number and the information is given to a code recognition means 13. Then, the means 13 conducts code recognition using the pitch information of the note.on given by the means 12. Thus, all inputted pitch information are not used for the code recognition and the number of pitch information is limited. Thus, the processing speed is improved because the code recognition is performed using a less number of pitch information.

IPC: H01L21/30
Filed: 1984-05-07
Abstract: PURPOSE:To automate circular arrangement of chip pattern by effectively selecting a chip through comparison between chip arranging information and wafer standard, obtaining a circular arrangement from such selected chip and controlling an electron beam lithographic apparatus based on such arrangement. CONSTITUTION:A chip arrangement 17 and a wafer 18 are respectively divided into four sections and only the first quadrant is delineated. A distance from the center position 0 to the upper or upper right corner of each chip 17a l1-l5... is obtained. The chips having such distance l1-l5... which is smaller than the radius (r) of wafer 18 are receptive, while the chips having such distance which is longer than the radius (r) of wafer are not receptive. The control part 14 develops a chip symmetrically in the directions of (X) and (Y) axes based on such chip selected in a comparator 13 in order to obtain the 2nd to 4th quadrants, thereby obtaining a circular arrangement. A lithographic apparatus 15 is controlled on the basis of this circular arrangement and thereby a chip pattern corresponding to the circular arrangement is transferred on a mask substrate 16. Thereby, circular arrangement of chip can be obtained automatically, eliminating erroneous operation, curtailing the time required for constituting arrangement and thereby improving efficiency.

Title: Recording apparatus
Inventor: SOGAMI ATSUSHI
IPC: B41J2/32
Filed: 1987-04-10
Abstract: PURPOSE:To facilitate control and to magnify resolving power and the number of gradations, in performing gradation recording, by changing the combination of the number and kind of pixels to be printed to change the printing density within a unit sectional region. CONSTITUTION:A 4X4 matrix constituted of 16 pixels is set to a unit sectional region and, when the density within the unit sectional region is changed by changing the number and kind of the pixels to be printed within the unit sectional region, printing of 84 gradations can be performed. When the ratio of the cross-sectional areas of recording electrodes 4 is properly selected, the number of gradations are increased and expression of many gradations can be performed. Since each of the recording electrodes is allowed to print only a preset single pixel and allowed to perform printing in a saturated region, stable printing can be performed. Even if the voltage or pulse width applied to each recording electrode is not changed, each recording electrode is switched under the same condition and, only by changing the combination of the number and kind of pixels within the unit sectional region constituted of the pixel matrix, a large number of gradations can be expressed and printing can be performed under easy control.

Title: Return water control unit for air conditioning
Inventor: KAMATA KOUJI
IPC: F24F3/14
Filed: 1978-07-21
Abstract: PURPOSE: To enable the use of a single main return pipe to discharge water from a number of air washers, at least some of return water branch pipes are made of flexible pipe and enclosed by water pressure of the main return pipe and check valve is provided downstream the flexible return pipe.  
     CONSTITUTION: Cold water sprayed from spray nozzle 44, after exchanging heat with air, falls on the water receptable 14 causing its water level to rise up. The flexible pipe 30 passing within the tank 3 contains water with pressure of head H 1  higher than that in the tank 3 connected to the main return pipe 13. This causes the flexible pipe 3 to expand, permitting water in the water receptacle 14 to pass through the return branch pipe 16 to the main return pipe. When the spray stops, the main return pipe 18 has a pressure different for different altitude of the washer 10 installation, which is either higher or lower than atmospheric pressure. When higher than atmospheric pressure, the check valve 34 is closed. If lower than atmospheric pressure, the flexible pipe 30 is depressed in the tank by head H 2  of the main return pipe 18.

Abstract: PROBLEM TO BE SOLVED: To improve moisture stability by providing a sensitive layer that is formed by a semiconductor with indium oxide as a main constituent and covers a noble metal wire and forming a compact silica thin film on the sensitive layer. SOLUTION: An indium hydroxide pulverized body is baked to obtain the particle of indium oxide. It is further formed into fine particles and is changed into paste shape by such dispersion medium as 1,3-butanediol, and is covered with a noble metal wire 1 for coating spherically. Current is fed to the noble metal wire 1 after drying and the wire 1 is baked in air, thus obtaining a radiation-type semiconductor gas detection element consisting of a sensitive layer 2 only. It is heated under the environment of the room temperature saturation steam pressure of, for example, hexamethyldisiloxane. The heating is made so that current is fed to the noble metal wire 1 for generating Joule heat and the temperature of the entire sensitive layer 2 exceeds the decomposition temperature of hexamethyldisiloxane.  As a result, the hexamethyldisiloxane in atmosphere is thermally decomposed and a compact silica thin film 3 is formed on the surface of the sensitive layer 2.

IPC: F24H1/14
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To effectually achieve heat exchange and hence ensure a sufficient amount of effluent hot water even when the size of a heat exchanger is reduced to the utmost by parallely supply water to a main heat exchanger and an auxiliary heat exchanger. SOLUTION: A main heat exchanger 2 is disposed upstream a waste gas flow passage 7 above a burner 1 and an auxiliary treat exchanger 4 downstream the same so as to be overlapped vertically putting a drain pan 6 therebetween. The diameter of water pipes 3 constituting the auxiliary heat exchanger 4 is made finer than that of water pipes 5 of the main heat exchanger 2, whereby the water pipes 3 are densely disposed, and water is supplied parallely to the water pipes 3 and 5. Hereby, even when the diameter of the water pipe 3 constituting the auxiliary heat exchanger 4 is made finer, overall water supply resistance is prevented from being increased so that heat exchange is effectulally achieved and the satisfactory amount of effluent hot water is realized.

Title: Voice output unit of programmable controller
Inventor: TSUBAKIZAKA MASAZUMI
IPC: G05B23/02
Filed: 1985-04-26
Abstract: PURPOSE:To generate the next voice signal without interrupting a current generated voice signal by providing a means which generates a voice generating command after a generating command if the voice signal is generated when presence of an output start command is detected. CONSTITUTION:A microprocessor (MPU) 501 takes in data from a system bus DB and decodes it as a voice output instruction to detect presence/absence of the output start command and presence/absence of a preferential output command. Presence/absence of the preferential output command is set by reading the state of a preference function selecting switch (corresponding to the 0th bit of a DIP switch 54). When absence of the preference function is detected, the voice generating command related to a detected message number is issued immediately if the voice signal is generated, and the voice generating command related to the next message number is issued successively after the end of generation of the voice signal if the voice signal is generated.
