Title: Noise attenuator
Inventor: IWABUCHI GORO
IPC: H01F1/14
Filed: 1993-04-16
Abstract: PURPOSE:To provide a compact noise attenuator at a low cost in which the suppression of a noise can be sufficiently attained without increasing the capacity of a capacitor or the number of steps of a filter. CONSTITUTION:A balanced inductance coil 1 using a toroidal core 1A made of an iron-base microcrystal soft magnetic material is cascade-connected with a balanced inductance coil 2 using a toroidal core 2A made of a ferrite so that a filter can be constituted. Therefore, noise components in a high frequency area are blocked by a part constituted of the balanced inductance coil 2 using the toroidal core 2A made of the ferrite, and the noise components in a low frequency area are blocked by a part constituted of the balanced inductance coil 1 using the toroidal core 1A made of the iron-base microcrystal soft magnetic material. Thus, the noise in a wide frequency range can be effectively suppressed.

Title: Tension controller
Inventor: MATSUNAGA TAKASHI
IPC: B29C65/48
Filed: 1993-04-16
Abstract: PURPOSE:To prevent formation of flares at bonding parts at the time of machining when plastic films are automatically and continuously laminated by installing a tension controller between the feeding device and bonding device of a plastic film bonding facility, the tension controller comprising a balance detector and a balance adjustor. CONSTITUTION:When a film 1 is sagged, a roll 3 is lowered and a semicircular gear 6 is rotated about a balancing shaft 5, and at the same time the speed of rotation of the electric motor of a feeding device is reduced in response to an electric signal produced by a balance adjustor B comprising a balance detecting gear 8 which operates in conjunction with the gear 6 and an amplifier 10, and the tension of the film 1 returns to its original state. When a film 2 is sagged, the speed of rotation of the electric motor is reduced likewise. The speed of rotation of the electric motor of the feeding device is thus adjusted so that the tension of the film 1 is the same as that of the film 2. Therefore no flare is formed at the bonding portion of the films during machining by a difference in tension.

Title: Hot water tank
Inventor: YAMAZAKI HIRONORI
IPC: E03D9/08
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To extend a time for feeding hot water from a tank body at the preset temperature level, regarding a hot water tank used for a hygienic washing device. SOLUTION: A water inlet pipe 50 for introducing water from a water supply source to a tank body 40 has a feedwater pressure cushioning chamber 52b at an intermediate position. The feedwater pressure cushioning chamber 52b is used for the partial expansion of the cross sectional area of the water inlet pipe 50 and acts to weaken and straighten a water flow. As a result, water flowing from the water inlet pipe 50 to the tank body 40 does not agitate hot water contained in the tank body 40. Thus, a time to deliver hot water from the water inlet pipe 50 at the preset temperature is extended.

Filed: 1994-04-05
Abstract: PURPOSE:To provide a bearing which can be operated for a long time with no supply of oil, and which is lightweight so as to reduce inertia force and shock upon abrupt acceleration or deceleration, by forming the bearing from resin dispersed therein with carbon fibers, in a substantially cylindrical shape. CONSTITUTION:A needle bearing 1 is columnar, having a diameter (d) and a length L which is relatively larger than the diameter (d). A rod-like resin stock dispersed therein with carbon fibers, is cut into a predetermined length, and is then machined into the needle bearing 1 having a desired shape and dimensions. Alternatively, heated molten fluid resin dispersed therein with carbon fibers is cast under pressure into dies formed in a desired shape and having desired dimensions, and thereafter, it is cooled and cured so as to have the needle bearing 1. Polyacetal dispersed therein with carbon fibers is used as the resin dispersed with carbon fibers. With this arrangement, it is possible to maintain satisfactory lubricativeness so that no abrasion or seizure occurs. Further, since the bearing is relatively lightweight, the inertia force thereof is small even though abrupt acceleration and stopping are repeated, thereby it is possible to reduce shock.
