IPC: F27B3/08
Filed: 1989-11-07
Abstract: PURPOSE:To provide a batch type baking furnace of energy saving type by baking an article by use of hot air from a hot air production device and heat of an electric heater. CONSTITUTION:When large hot energy is needed, hot gas obtained by burning fuel gas substantially completely by using burners 11, 13 and their combustion chambers 12, 14 is introduced into a furnace body 2 through the hot gas inlets 21-23 and hot gas inlets 15-17 for heating an article to be baked. When required thermal energy is relatively small, the article disposed in the furnace body 2 is heated by electric heaters 6, 8, 9 disposed in the furnace body 2. Accordingly, the article is baked by an optimum energy source depending upon a baking process or a purpose and hence strong points of both a gas furnace and an electric furnace are demonstrated. Hereby, a baking furnace with reduced energy consumption can be obtained.

Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a remote controller that uses a conventional mobile phone terminal so as to remotely control equipment. SOLUTION: When the conventional mobile phone terminal 10 makes a specific operation to control equipment 29, the terminal 10 transmits operation data and a reception antenna 14 of an equipment controller 12 receives the operation data. A reception section 16 demodulates the received data. An authentication section 18 confirms whether or not an identification code included in the demodulated signal matches a registered code. When the identification code is confirmed, an operation data analysis section 20 analyzes the operation data included in the demodulated signal. A control section 22 transmits a control signal corresponding to the analyzed contents. A corresponding device of the equipment 29 receiving the control signal executes a corresponding operation.

Abstract: PURPOSE: To improve the efficiency and productivity of sputtering by packing an insulating means into the large back space disposed between a substrate electrode and a shielding means and increasing high-frequency impedance to the ground.  
     CONSTITUTION: A target is sputtered by impressing a high-frequency voltage between a target electrode (not shown in Fig.) holding a target member and the substrate electrode 26' holding substrates 30 via a substrates holder 28' and generating a glow discharge between both electrodes, by which thin films are formed on the substrates 30.

Title: Ultrasonic flowmeter
Inventor: NABESHIMA NORIYUKI
IPC: G01F1/66
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To obtain an ultrasonic flowmeter which can be driven with battery by reducing power being consumed through the electronic circuit at receiving wave detecting section and to eliminate the adverse effect of noise undesired for receiving an ultrasonic wave. SOLUTION: At the time of forward time measurement, a transmitter/receiver 2 conducts transmission and a transmitter/receiver 3 conducts reception. A transmitter/receiver drive section 6 receives a first command signal from a control section 7 and excites the transmitter/receiver 2 to emit an ultrasonic wave. A timer 11 delivers an ON signal immediately before the ultrasonic wave arrives at the transmitter/receiver 3. Consequently, the power supply control part 12 at a receiving wave detecting section turns on power thereof. Upon detecting a receiving wave, the power supply control part 12 interrupts power supply to the receiving wave detecting section 4. Consequently, the receiving wave detecting section 4 operates for a minimum time interval required for reception thus reducing power consumption.

Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To obtain a molding having excellent inorganic fine particle dispersibility by setting its particle size to a specific value or more, or the number of aggregated lumps to a specific value or less in an SEM photograph. SOLUTION: Fine particle-containing polyester molding is obtained by setting a particle size to 1.5 μm or more in a range of 300 μm<2> or number of aggregated lumps to 10 pieces or less in an SEM photograph. The method for manufacturing the molding comprises the step of vacuum evacuating a biaxially kneading extruder having an L/D of 30 or more from its inlet via a vent part having the L/D of a range of 10 to 20. In this case, a set temperature of a cylinder of the extruder is a [melting point +5] deg.C or lower of the used polyester. As a type of the particles contained in the polyester, in addition to general purpose inorganic fine particles, carbon, calcium carbonate, alumina, inorganic deodorant, antibacterial agent or the like is used. As a result, dispersibility of the particles is upgraded.  For example, even in the case of molding fiber, film or the like by using a molding such as a chip or the like, its processability is upgraded.

Title: Document processor
Inventor: IKEO TSUNEJI
IPC: G06F17/21
Filed: 1990-10-31
Abstract: PURPOSE:To prepare an easy-to-read document by setting a layout so that a group of character strings showing the meaning of a word (idiom), a phrase, etc., is not parted into two lines. CONSTITUTION:A Japanese document when inputted from an input device 2 is properly divided by a document dividing means 4. A character array means 5 arrays a character string, sandwiched between adjacent punctuations of the document divided by the document dividing means 4, on a free space on the same line in order. A character string length judging means 6 judges whether a character string to be arrayed next is too long to put in the free space up to the end of the line and when it is judged that the character string can not be put in the free space up to the end of the line, a line end processing means 7 performs a carriage return process. Therefore, the group of character strings such as idioms and phrases in the document is never parted into two successive lines. Consequently, the easy-to-read document is created.

Title: Pressure relieving device for sealed container
Inventor: MASUO YUJI
IPC: H01H33/575
Filed: 1994-11-02
Abstract: PURPOSE: To prevent a pressure relieving plate inside the pressure relieving port of a sealed container from being eroded by electric arcs by providing an arc horn in the vicinity of the fixing points of the pressure relieving plate. CONSTITUTION: A sealed container 2 in which SF6 gas is enclosed houses a switch and is provided with a pressure relieving port 2a for safely discharging the SF6 gas so that the container 2 does not burst when the pressure of the gas increases due to an internal short circuit, etc. In addition, a metallic arc horn 7 is provided inside the port 2a. The arc horn 7 works as a protective electrode which prevents the transfer of arcs to a pressure relieving plate 4. Since the fixing points of the plate 4 press by a pressing plate 5, the plate 4 is deformed and the internal pressure of the container 2 is discharged to the outside through the port 2a.  Some of the electric arcs generated in the container 2 are led to the port 2 by the electromagnetic force of an electric current caused by the arcs or a discharged gas flow, the arcs are transferred to the arc horn 7 which is at the same potential as that at the container 2 and the plate 4 is not eroded nor scattered by the arcs.

Title: Area array semiconductor device, printed board and screen mask
Inventor: KIMURA AKIFUMI
IPC: H05K1/11
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To prevent defective soldering or generation of a solder ball due to warp at the time of heating. SOLUTION: Thickness of a solder paste 8 being printed onto each pad 7 is increased depending on the warp of a BGA package and the area of each pad 7 is set depending on the sum of the quantity of solder of an electrode ball 4 arranged on the lower surface of the BGA package and the quantity of solder of the solder paste 8. The BGA package is warped when it is heated while being mounted on a printed board but defective soldering can be prevented because the solder paste is printed at a thickness corresponding to the warp. Since the area of each pad 7 is set depending on the sum of the quantity of solder of the electrode ball 4 and the quantity of solder of the solder paste 8, solder does not flow over the pad even if the solder is collapsed due to the weight of the BGA package or unwarping at the time of cooling and generation of a solder ball or a solder bridge can be prevented.
