Title: Portable air pump
Inventor: HATASAKI YASUZOU
IPC: F04B39/12
Filed: 1983-12-02
Abstract: PURPOSE:To prevent water, etc. from flowing into an air pump, by providing at a part of a body case a suction port and a discharge port which are externally projected from the body case and are communicated with an air pump in the body case, the suction port being provided with an air intake opening and covered with a cap of waterproof structure. CONSTITUTION:A suction port 8 and a discharge port 9 which are communicated with a power air pump 2 incorporated in a body case 1 are provided at a part of the body case 1 in such a manner as to externally project from the body case 1. In this manner, as outside air is directly sucked through the suction port 8 into the air pump 2, and is discharged from the discharge port 9, there is no possibility of rainwater or seawater flowing into the body case 1 simultaneously with suction of air as has conventionally occurred, and therefore corrosion of electrical parts in the body case 1 may be prevented. Further, as the suction port 8 is provided with an air intake opening 21 and is covered with a cap of waterproof structure, water and the like may be surely prevented from flowing into the air pump 1.

Title: Production of porous glass preform for optical fiber
Inventor: SUZUKI RYOJI
IPC: G02B6/00
Filed: 1989-09-04
Abstract: PURPOSE:To improve the deposition efficiency of glass fine particles even when the outer diameter of a glass fine particle-deposited layer is increased by changing the direction of a burner so as to be satisfied with a specific conditions with the increase of the outer diameter of the glass fine particle-deposited layer when a porous glass preform for an optical fiber is produced by an outer-coating method. CONSTITUTION:In a method for producing a porous glass preform for an optical fiber by feeding a glass raw material into the flame 4 of a burner 3 for synthesizing glass fine particles to produce the glass fine particles and adhering the produced glass fine particles on the periphery of a central member 1 to form a porous glass fine particle-deposited layer 2, the following processes are adopted. As the outer diameter of the deposition layer 2 is increased, the direction of the burner 3 is changed so that an angle theta between the axis of the burner 3 and the contact line of the surface of the deposition layer at the cross point of the axis of the burner 3 with the surface of the glass fine particle-deposited layer 2 may substantially be fixed within a range of 40-80 degree. The further transfer of the burner 3 in the direction separating from the central member 1 with the increase of the outer diameter of the deposition layer so that the distance of the burner 3 from the surface of the deposition layer 2 may substantially be fixed permits to further heighten the effect.

IPC: F16L13/00
Filed: 1988-09-13
Abstract: PURPOSE:To obtain an enough seal pressure by forming a tube fitting by a shape memory alloy and forming an outer cylinder portion and an inner cylinder portion in such a manner as to extend from the central portion where the end portion of a connecting pipe is pressed on both sides like a double cylinder. CONSTITUTION:A tube fitting 1 is formed by extending an outer cylinder portion 3 and an inner cylinder portion 4 from the central portion 2 on both sides. The extension length of the inner cylinder portion is made shorter than the extension length of the outer cylinder portion 3. The forward end portions 3a and 4a of the outer cylinder portion 3 and the inner cylinder portion 4 are gradually decreased in thickness as they are directed to the forward ends. The tube fitting 1 is formed by a shape memory alloy such as Ni-Ti group alloy, Cu-Zn-Al group alloy, Fe-Mn-Si group alloy or the like. Accordingly, when the tube fitting is subjected to heat treatment, the pipe is tightened from both sides by the outer cylinder portion and the inner cylinder portion so as to obtain enough seal pressure without deforming the tube. Further, a high strength for tensile load or bending load can be obtained.

Abstract: PURPOSE:To obtain a lamp for a ultraviolet light source to which only mercury starting discharge at a room temperature is enclosed, by staring discharge using a device for externally applying a high electric field of a DC or AC current when the lamp for the ultraviolet light source is lit. CONSTITUTION:High frequency power is applied to a pair of electrodes 3 for applying high frequency power disposed in a light source bulb to which only mercury starting discharge at a room temperature is enclosed from a high frequency power source 7 via a coaxial cable 5 and a matching device 6. Although discharge is not started in the state even if matching is effected, the application of a high voltage to electrodes 8 for applying high voltage from a high voltage generating circuit 10 via a high voltage cable 9 causes mercury vapor in the light source bulb 1 gripped between the electrodes 8 to ionize to produce plasma so that discharge occurs between the electrodes 3 for applying high frequency power. Then, the discharge between the electrodes 3 is maintained even if the high voltage cable is shut off.

Title: Ink ribbon cassette
Inventor: ARA YOJI
IPC: B41J31/00
Filed: 1986-09-30
Abstract: PURPOSE:To obtain a high-quality print with stable density which is not influenced by ambient temperature, by pivoting an ink roller to a cassette case movably in the axial direction of a ribbon feed roller, then pressure contacting a spring against the shaft and loading the shaft toward the ribbon feed roller. CONSTITUTION:An ink roller 18 is loaded toward a ribbon feed roller 13 by a compression spring 23 pressure contacting with a roller shaft 22. The diameter of the ink roller 18 expands as the ambient temperature rises and shrinks as the ambient temperature lowers, but since the roller shaft 22 is pivoted slidably to a bearing hole 21, the ink roller 18 contact neither the ribbon feed roller 13 with excessively strong pressure nor quite low pressure. When a bimetallic or shape-memory alloy is employed for the compression spring, the compression spring can be deformed to weaken the spring force under high temperature and to strengthen the spring force under low temperature so as to further stabilize the pressure contacting force of the ink roller 18 irrespective of the ambient temperature.

Title: Solar heat utilizing device
Inventor: HATSUTORI MASAJI
IPC: F24S90/00
Filed: 1983-12-06
Abstract: PURPOSE:To enable to utilize the low temperature air generated at heat collector for cooling indoor by a method wherein the heat collector is attached on a part of outer walls and a fan is arranged above the heat collector and the operations of a pump and of the fan are controlled by the hot water temperature detector of a heat storage tank. CONSTITUTION:When a solar switch 23 is turned ON, because of the hot water temperature being low, a pump 6 and a compressor 2 are started in order to raise the water temperature. When the hot water temperature reaches the set value, a hot water temperature detector 13 is changed-over to a normally open contact 13a side and a contact 13' is made open, resulting in ending the heat collecting operation. When the cooling operation is to be performed, a cooling switch 24 is turned ON. When the hot water temperature is low, the pump 6, the compressor 2 and a fan 20 are put into operation, resulting in forcibly sending the cooled air into a room in order to perform cooling. At the same time, the heat collecting operation is performed by storing the collected heat in a heat storage tank 12. When the hot water temperature rises further higher due to the continuation of the heat collecting operation, the hot water temperature detector 13 is changed-over to a normally open contact 13b side so as to bring an air cooling fan 18 into actuation in order to thermally discharge the high temperature of a heat exchanger 8. Consequently, the breakage of the heat storage tank 12 due to overheating by abnormal heating is also eliminated.
