Title: Brine generator
Inventor: NAKAKUKI YASUHIDE
IPC: B01D61/36
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To obtain a brine generator reduced in the consumption of energy and needing only a small floor space for the equipment. SOLUTION: Seawater 90 is stored in a concd. brine tank 24 by operating a raw water pump 12, and then the seawater 90 in the tank 24 is heated by operating a circulating pump 34 and a heat source 40 and circulated between the tank 24 and a membrane-distillation membrane module 18. The unheated seawater 90 is simultaneously passed through the inside of the module 18. Consequently, only fresh water is extracted from the seawater being circulated in the module 18 and stored in a fresh water tank 46. Accordingly, the seawater being circulated is gradually increased in salinity with time according to the amt. of the fresh water extracted, the circulation is stopped when the salinity of the seawater stored in the tank 24 reaches a desired salinity. As a result, the brine of the desired salinity is obtained.

Title: Picture coding system
Inventor: OGURA KOJI
IPC: G06T9/00
Filed: 1989-02-27
Abstract: PURPOSE:To relieve the excess load of a processing to a post-stage multi- processor by adjusting a threshold level for coding implemented by a pre-stage multi-processor depending on the data storage quantity of a buffer placed between the pre-stage multi-processor and the post-stage multi-processor and controlling an effective block number to the constant. CONSTITUTION:As for input data inputted from an input terminal 1 and stored in an input frame memory 4, the pre-stage processing such as movement compensation, conditional picture element supplement, etc., are executed by a processing unit in the pre-stage multi-processor 5 and its result of processing is outputted to a buffer 7. The block data stored in the buffer 7 is subjected to a post-stage processing such as vector quantization, discrete COS transformation and decoding by a post-stage multi-processor 6. An output control section 8 sends a feedback data to the pre-stage multi-processor 5 to control a threshold level, thereby limiting the quantity of production of a coded data to the constant. Thus, the load of the post-stage multi-processor 6 is relieved.

Title: Blower for ventilating duct
Inventor: KAZAOKA MOTOHIRO
IPC: F24F7/10
Filed: 1989-02-27
Abstract: PURPOSE:To discharge air in a living room and malodor remaining in a duct, to simplify the execution of installation work, and to reduce its cost by a method wherein a damper is controlled by a control section to close an opening communicating to a washroom and the like after a switch for the washroom has been turned OFF, and a blower is operated for a predetermined period of time. CONSTITUTION:When a switch 46 for a washroom is turned OFF, a timer in a control section is impressed to continue the operation of a blower during a predetermined period of time. A damper is regulated to close an opening communicating to a washroom 21 and open a connecting port on the side of a living room 20 so as to communicate to a first duct 25, and air in the living room 20 is thus exhausted through the first duct 25. More particularly, after a toilet has been used, malodor is once discharged through a second duct 30; however, since malodor may more or less flow into the first duct 25 and the living room 20, the damper is switched over for a predetermined period of time to exhaust air in the first duct 25 and the living room 20. According to this method, a single exhaust device has only to be set and the work of penetrating through beams has only to be done at one place, thus enabling the execution of installation work to be simplified.

Title: Piezoelectric vibrator component
Inventor: SUGIMURA TOSHIAKI
IPC: H03H9/10
Filed: 1990-02-26
Abstract: PURPOSE:To relax a tightening stress from an outer package resin while keeping an effect damping an internal piezoelectric element by providing a silicone rubber foaming body to coat a vibration region of the piezoelectric element and coating the surrounding of the piezoelectric element coated by the silicone rubber foaming body with the outer package resin layer. CONSTITUTION:A piezoelectric ceramic board 1 is covered by a silicone rubber foaming body 17 and the outside of the silicone rubber foaming body 17 is further covered by an outer package resin layer 8. The silicone rubber foaming body 17 has only to be arranged at least to a vibration region, that is, only at the region where split electrodes 2, 3 and a common electrode are formed and at the surrounding of the peripheral region. Since lots of air bubbles are dispersed in the silicone rubber foaming body, the tightening stress by the outer package resin layer due to deformation and compression of the air bubbles is effectively relaxed. On the other hand, the specific gravity of the silicone rubber in the contact face with the element rather than the elasticity of the silicone rubber is much effected on the effect damping the piezoelectric element. Thus, the damping effect in not much reduced.

For example, when the voltage between the terminals is under the command set by a Zener diode 102, a transistor (Tr) is off and Tr 111 is on. When the voltage between the terminals is risen to the set voltage, Tr 104 is on and Tr 111 is off for starting the charging of a condenser 114 through resistances 112 and 113. When the condenser voltage is risen to the set voltage set by resistances 115 and 116, a gate signal is given from a comparator 117 to the thyristor 5.

Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To reduce the rotational torque by using spherical bodies of different curvature by the part of the surface for rolling elements to discharge excessive grease outside a raceway track in a short time. SOLUTION: A spherical body whose section passing through the center of the spherical body is approximate to the distorted circle of equal diameter having three peaks, is used for a rolling element 3, and when it is rolled on a raceway surface groove R5, in the beginning, grease is present in a space 7-a constituted by the groove R5 and the R dimension 6-a, where 6-a is the R dimension of the spherical body 3 on the same section as the groove R5. When the spherical body 3 is rolled on the raceway surface, and brought into contact by the R dimensions 6-b, 6-c at the position of large R dimension of the spherical body, the space 7-a is narrowed by the dimensional change into 7-b, 7-c. Grease present in the space 7-a is extruded from the raceway groove.  When the rolling is advanced from the R dimension 6-d to the position 6-e, 6-a at the position small in R dimension, the space is expanded to 7-e, 7-a, but grease is slightly returned by its viscosity, and the quantity is small, and the rotational resistance can be reduced.

Abstract: PURPOSE:To reduce press-in force by providing a clutch member to a motor-side bear between two gears which are coupled together through a spring member, absorbing the horizontal movement extent of a cassette holder by the spring member, and inhibiting the spring member from expanding during vertical movement. CONSTITUTION:When a cassette 1 is pressed in, the cassette holder 2 is also pressed simultaneously, guide pins 2a and 2b move along guide grooves 3a and 3b respectively, and a link 20 also moves while rotating, so that a driving arm 10 rotates clockwise. Then, a driving gear 9 also rotates clockwise by being pressed with the driving arm 10, and a synchronous gear 17 engaging the driving gear 9 and further a spring peg gear 7 also rotate. A loading motor 4, however, stops and a worm wheel 6 engaged with a worm gear 5 which is coupled directly with the motor does not rotate, and the movement of the cassette holder 2 is absorbed through the expansion of a torsion coil spring 8. For the purpose, a spring with weak force is used as the spring member which absorbs the movement of the cassette holder to move the cassette holder smoothly.
