Title: Vacuum cleaner
Inventor: MIYAHARA TOSHIFUMI
IPC: A47L9/24
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum cleaner providing a high suctional force steadily by absorbing the size variation of a molded check valve to increase the airtightness. SOLUTION: The vacuum cleaner has an intake pass 4 for intake gas, which is sucked by an electric blower 2, in front of a dust collection room 3. A check valve 5 made of an elastomer is placed between the intake pass 4 and the dust collection room 3 to connect them. The check valve 5 has a hollow part 6 which is a closed space. When the electric blower 2 starts sucking, the pressure in the dust collection room 3 becomes a negative pressure against the atmospheric pressure. Consequently, the hollow part 6 of the check valve 5 expands and the gap between the check valve 5 and the main body 1 decreases. As a result, the airtightness of the dust collection room 3 and the intake pass 4 is improved and the sucking force is increased.

Title: Heating device in nitrogen gas atmosphere
Inventor: OGINO TADAO
IPC: C21D1/76
Filed: 1993-12-17
Abstract: PURPOSE:To contrive to improve safety, by setting a valve wherein a feeding of a hydrogen gas from a hydrogen gas feeding source becomes possible only when a nitrogen gas feeding detector detects a feeding of a nitrogen gas. CONSTITUTION:A nitrogen gas feeding device 33 is equipped with a nitrogen gas feeding detector 55 detecting a supply condition of the nitrogen gas to a heating furnace 31 and an opening or shutting valve 57 executing an on-off of a supply of a hydrogen gas. The nitrogen gas feeding detector 55 detects a flow quantity or a pressure of the nitrogen gas fed to the heating furnace 31 from the feeding device 33 by respective sensors, and detects whether a predetermined pressure or a predetermined flow quantity is attained or not. The opening or shutting valve 57 is composed of an electromagnetic valve and the like and acts according to a signal from the detector 55. That is to say, when an adequate feeding of the nitrogen gas to the heating furnace 31 is detected the opening or shutting valve 57 is opened and when it is not adequate, a shutting is executed and a cuttoff of a supply of a hydrogen gas is executed. By this, it can be prevented that only the hydrogen gas is fed without feeding of the nitrogen gas to the heating furnace 31 and safety can be ensured.

IPC: B41J2/205
Filed: 1989-12-27
Abstract: PURPOSE: To suppress degradation of image due to a damaged nozzle by forming each dot of two ink droplets of the same color and ejecting respective droplets from different nozzles thereby enhancing the quality of dot. CONSTITUTION: Nozzles 18 are arranged substantially in line while being staggered from left to right in a nozzle plate 16. A nozzle divided into two groups 54, 56 is employed in order to deposit two droplets from one print head at the time of continuous passage. The print head traverses a print medium in a direction 52 and droplets are deposited in a desired pattern by the first group of nozzles 54. Upon finishing passage, the print medium is moved by a distance in a direction shown by an arrow 74 and a stripe at print medium located under the first group of nozzles 54 is shifted under the second group of nozzles 56. The print head deposits ink droplets in totally identical pattern.  Since the nozzles of second group 56 are arranged identically to those of first group 54, the droplets deposited by the nozzles of second group 56 are superposed on the droplets deposited by the nozzles of first group 54.

Title: Hot water supplier
Inventor: YOSHIDA AKIRA
IPC: F24H1/10
Filed: 1992-12-02
Abstract: PURPOSE:To ensure the minimum amount of operation water even at a low water pressure without increasing lowest actuation water pressure by providing control means for driving a water amount adjusting valve in the direction of opening of the same to increase a flow rate, and starting hot water supply operation as the flow rate reaches the minimum amount of actuation water. CONSTITUTION:After a wait time is elapsed, a water amount sensor 9 detects that a flow rate becomes an initial flow rate of a predetermined fine flow rate or higher and a minimum actuation water amount or lower, whereby a counter included in a controller 15 starts to count down from an initial value. As the counting is continued until the count value gets zero and the elapse of a judgement time is confirmed, it is judged that water supply by a hot water supply starting operation is detected, and a water amount adjusting valve 12 equipped with an overflow prevention function is driven in the direction of opening of the same to increase the flow rate, and as the flow rate reaches the minimum amount of actuation water, the hot water supply operation is started. Hereby, there is ensured the minimum amount of actuation water even at low water pressure without increasing the lowest actuation water pressure.

SOLUTION: When fuel is injected from an injection valve 10 into a combustion chamber, the most part of the fuel is vaporized to be mixed with air, but a part of the fuel is guided close to a conductive member 20 as small liquid- drops in a stream of an isolator 17 of an ignition plug 11 to the opposite side. When ignition voltage is supplied to a center electrode 18, a strong electric field is formed in a range between a head 19 of the center electrode 18 and the conductive member 20 adjacent to the head 19 on a surface of the isolator 17. The strong electric field generates spark in each gap between the electrodes 16, 18 and the conductive member 20, and the spark extends from the first electrode 18 to the second electrode 16 over the conductive member 20, so that mixed air flowing around the isolator 17 is satisfactorily ignited.

Abstract: PURPOSE:To keep the positional relationship between each LED and a corresponding display window optimum always and to prevent obscure display and misdisplay by mounting the LEDs on a printed board through the medium of spacer members, and making support members hold the tip parts of the LEDs. CONSTITUTION:A plurality of LEDs 12 having a pair of protruding leads respectively on the base end sides of the luminous parts are mounted in array on a sub-board 11 through the medium of spacer members 13. Consequently, the leads of the LEDs 12 are reinforced by the spacer members 13, and the bending, etc., of the leads are lessened.

Besides, support metal fittings have tapered through holes 18a and hold the tip parts of the LEDs 12. Accordingly, correction of the positions of the LEDs 12 is performed smoothly, and it becomes possible to put them at optimum positions against the display windows of a label 21.
