Title: Nondirectional underwater ultrasonic transducer
Inventor: INOUE TAKESHI
IPC: H04R1/44
Filed: 1986-07-02
Abstract: PURPOSE:To have an acoustic radiation characteristic highly efficient over a wide frequency band and to attain a high-power transmission by coating a cylindrical ceramic piezoelectric oscillator with a sheet made of fiber reinforced composite material by winding around the circumference so that the direction of the fibers coincides with that of the center axis of the cylinder. CONSTITUTION:The sheet 21 made of the fiber reinforced composite material arrayed so that the fibers are along the direction of the center axis of the cylinder, is wound in multi-layers on the outer surface of the cylindrical ceramic piezoelectric oscillators 11 and 11' with organic adhesive between the layers. To facilitate said winding, the material is freperably elastic in the direction of X in order to easily form the transducer. For the material, glass-fiber reinforced composite material(G-FRP) or carbon-fiber reinforced composite material(C-FRP) may be appropriate. As a result, the effective mass per unit acoustic radiation area can be considerablly reduced, and the acoustic impedance matching with water is drastically improved. Thus a transducer effieinct for a wide frequency band can be obtained.

Title: Hollow thread module
Inventor: NOZAKI MASASHI
IPC: B01D63/04
Filed: 1987-06-25
Abstract: PURPOSE:To increase a filteration efficiency without increasing the flow resistance of filtered water in a collecting mechanism by gradually enlarging the cross section area of the collecting mechanism of a hollow yarn module formed by connecting stepwise the vertical bundle of hollow yarns arranged circumferentially to the collecting mechanism. CONSTITUTION:The cross section areas of intake pipes 2C, 2B and 2A at a hollow yarn module formed by stepwise connecting the vertical connection 5A and 5B of a bundle 4 of hollow yarns through connecter 6 are made so that 2C is smaller than 2B and 2B is smaller than 2A. The bundle 4 of hollow yarns is formed by arranging open ends hollow yarns 3 around the intake pipes 2 with open ends as a collecting mechanism. When raw water is treated with this kind of hollow yarn module suspended in a filteration column, the flow rate of filtered water in the intake pipes 2 becomes greater as the intake pipe 2 positions move upper; however, a flow resistance of the filtered water does not increase accordingly because the cross section area of the intake pipes 2 becomes larger stepwise.

Title: Line heater
Inventor: KIKUCHI YOSHIKAZU
IPC: H05B3/00
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To enhance accuracy of temperature detection of a fluid heated by a line heater. SOLUTION: This line heater is equipped with a passage for a fluid such as air, a rod-shaped heating part 2 disposed in the passage along the stream of the fluid in order to heat the fluid, and a temperature detecting part 3 disposed in the passage on the downstream side of an end of the heating part 2 and detecting the temperature of the fluid. An end part 20 of the heating part 2 facing to the downstream side is so formed as to taper down toward the downstream side. Because the downstream side end part 20 of the heating part 2 gradually expands the passage for the fluid that is going to pass by the heating part 2, turbulence is not produced in the fluid. Resultantly, the temperature after heating the fluid detected downstream of the heating part 2 by the temperature detecting part 3, can be detected with enhanced accuracy.

Title: Electrostatic recording film
Inventor: KUROYAMA YOSHIHIRO
IPC: G03G5/14
Filed: 1985-07-18
Abstract: PURPOSE:To provide substantial adhesive strength to a substrate to the titled film and to eliminate grazing even when the film is subjected to recording by an electrostatic printer plotter by consisting a conductive layer of flake mica powder coated with antimony solutionized tin oxide and org. binder. CONSTITUTION:The flake mica powder coated with the antimony solutionized tin oxide is used on the both surfaces of the film substrate, by which the same effect is obtd. even if the conductive material is compounded therewith at the lower ratio as said tin oxide has the larger specific surface area than the specific surface area of the conventional metallic oxide such as spherical tin oxide or zinc oxide. The electrostatic recording film having excellent quality is thus formed by forming the conductive layer together with >=30wt% org. binder and providing a dielectric layer (recording layer) on one conductive layer thereof. Since the micaceous particles to be used are flat, the particles have the larger specific surface area than the spherical particles even if the content thereof is <=70wt%. The contact of the particles with each other is thus maintained and the electrical conductivity is developed. The addition of >=30wt% org. binder to the conductive layer is thereby permitted, by which the film strength and the adhesive strength to a base material are improved and the grazing in the stage of recording is prevented.

Abstract: PROBLEM TO BE SOLVED: To efficiently detect the current position of a predetermined block area with simple configuration and also easily detect the origin of a rotor even if a part of a detecting means gets out of order by arranging identifiers in a plurality of block area provided in a rotor, and arranging plural detecting means in the periphery of the rotor. SOLUTION: Among a plurality of block areas 21 formed by dividing a rotor 20 by the equal angle, identifiers (identifying mark or the like) 22 are arranged in three areas 21, for example, the identifiers 21 are detected by a plurality of detecting means 23 (sensors 1-3) arranged in the periphery of the rotor 20, and according to a logic pattern of the logic output data of the detecting means 23, the existing position of a selected specified area 21 is discriminated by a discriminating means 24. In this arrangement, when a part of the plurality of detecting means 23 gets out of order, the defective detecting means 23 is excluded from the inspection operation, and only the remaining detecting means 23 are used to recognize the origin of the rotor 20. Thus, the select operation for a predetermined area 21 can be continuously executed.

Title: Thermo-sensitive device
Inventor: NAGAMURA TORU
IPC: H01H37/04
Filed: 1988-06-24
Abstract: PURPOSE:To prevent poor contacting because of slide wear dust by connecting a contacting plate with a pair of terminal plates when the outer frame is lifted by the pressing force of a spring, lifting the contacting plate by a fixed shaft when the outer frame comes in contact with an object to be heated and sinks, and thereby separating this contacting plate from the terminal plates. CONSTITUTION:When there is no object to be heated 9, a thermo-sensitive device (outer frame) 3 is lifted by the pressing force of a spring 5, and a contacting plate 20 is put in electrical connection with a pair of terminal plates 13 to shortcircuit a thermo-sensitive element 8, which becomes free from electric supply to give a sensing output that there is no object 9. When object 9 is arranged above, the thermo-sensitive device is pushed down against the pressing force of the spring 5 to allow the contacting plate 20 to be held by a fixed shaft 19, and the two terminal plates 13 sink to separate from the contacting plate 20, and no more power is supplied to the thermo-sensitive element 8. Thus the contacting part does not slide between a conductive part and non- conductive part, but makes contacting and separation, so that poor contacting due to wear dust will no more be generated.

IPC: H04N7/173
Filed: 1995-06-23
Abstract: PURPOSE: To improve the utilization efficiency of communication channels by making communication possible even when the carrier waves of either one of an outgoing communication channel using the carrier waves for outgoing communication and an incoming communication channel using incoming carrier waves are used. CONSTITUTION: The channels of a CATV are constituted of the carrier waves fd0 for outgoing control, the carrier waves fd1-4 for outgoing communication and the incoming carrier waves fw0-3. When a user requests the establishment of a communication channel to the CATV terminal equipment(TE), the TE checks a free allocation control channel from the received result of free channel broadcasting by the fd0 of the allocation control channel and requests a communication channel slot to the center unit by using the free channel. The center unit allocates a free outgoing communication channel Ddi from all the carrier wave channels to the TE. Thus, respective user terminals can utilize the communication channel of optional carrier waves and a time slot is effectively utilized.
