Title: Hybrid fuel cell
Inventor: MIZUNO YUTAKA
IPC: H01M10/615
Filed: 1990-03-22
Abstract: PURPOSE:To prevent drop of the capacity of a storage battery at a low temp. and preclude shortening of the battery life by controlling a heating means so as to maintain the battery temp. within a certain extent on the basis of the sensed temp. given by a temp. sensor. CONSTITUTION:A control part 33 controls the storage temp. within a certain extent at all times by changing over the flow path of a three-way valve 25 either to the heater 31 side or to the outside air side on the basis of a sensing signal given by a temp. sensor 32 of a storage battery 3. That is, when the battery temp. approaches the lower limit of the set extent, the flow path of the three-way valve 25 is changed over to the heater 31 side, and when approaches the upper limit, the flow path is changed over to the outside air side. Thereby capacity drop at a low temp. is prevented as well as shortening of the battery life precluded.

Title: Substrate exposure device
Inventor: IKUMI MASUZO
IPC: H05K3/00
Filed: 1990-03-22
Abstract: PURPOSE:To improve the quality of the title device by blowing out inert gas inward to the wall surface of a notch window of a mask holder. CONSTITUTION:A mask 2 is mounted on the surface of a mask holder 3 fitting to a notch window 1 of the holder 3 and then the holder 3 fitted to the notch window 7 of a mask base 5 is set in the alignment part on the exposure position of a peripheral part. When the whole body is vacuum sucked in such a state, the vacuum sucking trenches 6 of the holder 3 and those 8 of the base 5 are vacuum sucked so that the mask 2 may be sucked at the surface of the holder 3 likewise the rear surface of the holder 3 may be sucked at the surface of the base 5. At this time, the oxygen concentration in the gap between the mask 2 and a substrate 4 can be lowered due to the trenches 12 blowing out the inert gas on the wall surface inward thereby enabling the deterioration in oxidation of resist and the gas production on the substrate surface by the irradiated ultraviolet rays during the printing process to be avoided. Accordingly, a circuit pattern in high resolving power of securing proper ultraviolet ray irradiation can be printed thereby enabling both the quality and the productivity to be improved.

Title: Ink jet recorder
Inventor: TAKADA MASAYUKI
IPC: B41J29/13
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recorder capable of suppressing growing of bubbles existing in a supply passage formed on a print head to prevent ejection failure for a long time in a simple structure. SOLUTION: An opening section 61 for communicating a closed space 59 to the air is provided to a head cover 46 which forms the closed space 59 between a print head 23 and the cover 59. A heat generated by the print head 23 is discharged to the air via the opening section 61 so that a temperature and a pressure in the closed space 59 do not rise. Therefore, the air does not enter a supply passage 52 by virtue of a pressure difference so that it is possible to effectively suppress growing of bubbles staying in the supply passage 52.

IPC: H05K3/40
Filed: 1990-03-20
Abstract: PURPOSE:To make it possible to shorten a process by making the thickness of an insulating resin layer inferior to the quality of electroless plating substantially vertical to the length of an insulated portion of an electronic component which has an electrode on both ends and cap-mounted in a through hole. CONSTITUTION:An insulating resin layer 2, which is excellent in terms of electroless plating properties, is laid out on both sides of an insulating resin layer, which is inferior in terms of electroless plating properties while a through hole 4 is also provided thereon. The thickness T of a non-plating resin layer must be arranged to be substantially identical to the length (t) of an insulated portion 50 of an electronic component 5. The total thickness L of a lamination board is adapted to be substantially identical to or slightly larger than the whole length (l) of the electronic component 5. When they are processed based on the standard electroless plating process, using the lamination board having this structure, a plating section 6 will be turned into a plating resin layer alone so that it may be possible to provide metal to this section alone by further carrying out electric plating. The plating section 6 corresponds with the position of electrodes of the electronic component 5 to be surface-mounted, and thereby simplifiers the process.

Title: Timing signal generating circuit
Inventor: IWASE NOBUKAZU
IPC: G06F1/24
Filed: 1985-04-03
Abstract: PURPOSE:To output a timing signal after initialization even if reset signals (level) are continuously inputted by making the reset signals to become pulses having a fixed pulse width and using the pulses as the initializing signal of the timing signal. CONSTITUTION:When the reset signal (level) is inputted in a terminal A, pulses having a fixed pulse width are outputted to a terminal 5a by transfer gates TR2,...TR5 and a NAND gate N2. While a timing signal generating circuit 101 generates timing signals T1, T2 and T3 the timing signals T1, T2 and T3 are initialized to 'L' levels by the pulses of the terminals 5a. Since the pulses of the terminal 5a again return to 'L' after a fixed period has passed, the timing signal generating circuit 101 again generates timing signals.

In the oxidation process, absorption liquid after the desulfurization process is treated by gas containing oxygen.  In the double decomposition process, treatment liquid after the oxidation process is allowed to react with a basic calcium compound. Magnesium hydroxide regenerated in the double decomposition process is returned to the preceding process in a state containing gypsum dihydrate. In the desulfurization process, pH of absorption liquid is regulated to a range within 5.5-7.0 and COD is regulated to a range not exceeding the upper limit value decided by amount of magnesium sulfate contained in absorption liquid.

IPC: G01N33/53
Filed: 1988-03-23
Abstract: PURPOSE:To rapidly and efficiently fix trace nucleic acid components to various carrier films by using a photoreactive crosslinking agent having plural functional groups which can be crosslinked to nucleic acid base by UV irradiation. CONSTITUTION:The material for crosslinking and fixing DNA (e.g. solalene deriv.) having the plural functional groups which can make reaction bonding to the nucleic acid base under photoirradiation and the desired DNA are brought into contact with the film (e.g. nitrocellulose film, nylon film) for depositing DNA previously immobilized with denatured DNA different from the desired DNA and the contact region is irradiated (e.g. for about 10min) by the UV rays (e.g. 320-370nm), by which the desired DNA can be crosslinked to the carrier film and is fixed thereto. The denatured DNA (e.g. the DNA formed by denaturing the DNA of a salmon and herring) signifies one-chain DNA denatured by a heat or alkaline treatment. The nucleic acid is thereby released of the complementary bond and is held exposed. The material for crosslinking and fixing the DNA is eventually crosslinkable to such nucleic base.

Title: Automatic folding tester
Inventor: TERUI KOUKI
IPC: H04B17/00
Filed: 1982-04-27
Abstract: PURPOSE:To minimize the frequency of line interruption, by stopping the folding test for a prescribed time, after a failure in a reception signal is detected and the folding test is executed once. CONSTITUTION:When a receiver 1 is failed and its detection signal is applied to a logical circuit 7, an oscillator 3 is driven and a shifter 5 generates the same frequency as that of the reception signal with a transmission signal from a transmitter 4 and a signal of the oscillator 3. The generated signal is transmitted to the receiver 1 via a filter 6 and a coupler 8. When this signal is outputted to an output terminal of the receiver 1, the circuit 7 discriminates that the receiver 1 is normal, and when the signal is not outputted, the circuit 7 discriminates it as in failure. The circuit 7 stops the folding test for a prescribed time when the receiver 1 is normal. If fading takes place frequently in a short time, since the failure is detected because of the 1st fading, the folding test is stopped for a prescribed time and no folding test is exercised even if the fading takes place during the time.
