Title: Time capsule having solar battery
Inventor: ISHIHARA SHUNICHI
IPC: F24F7/06
Filed: 1989-03-08
Abstract: PURPOSE:To obviate the need for facility for fuel storage and permit a semipermanent use of a time capsule by keeping an air exhaust means supplied all the time with an output from a solar battery changeable dependent upon the amount of the sunlight received. CONSTITUTION:The electric power generated by a solar battery during the day drives a suction fan 5 and an exhaust fan 7 to replace the air inside a time capsule 1 with outside air. When the amount of the electricity generated by the solar battery becomes large, particularly in fine weather weather, the outside air of a low humidity in fine weather can be effectively drawn in the time capsule. On the other hand, due to a smaller amount of the electricity generated by the solar battery during the night or in rainy weather, the amount of the outside air of a high humidity drawn therein becomes smaller. In this way, the air inside the time capsule can be replaced automatically with the air suitable to storage.

Title: Dipped plate for fast breeder
Inventor: MOUTAI KATSUHIKO
IPC: G21C17/07
Filed: 1978-05-09
Abstract: PURPOSE: To promote a discharge of a upper plenum of FP gas in a cooling material, by shaping a slope at a dipped plate and by making gas exhaust holes on the slope.  
     CONSTITUTION: A dipped plate 18, which is located at and hanged down from a shelter plug 9 of a reactor container 1 through the medium of rods 17, are shaped in an angle, and gas exhaust are made at the respective tops of the angles. The plate 18 is dipped in an area, which covers an overall surface of the inside of the  reactor container 1 but keeps clear of a upper mechansim 8 and the like at the  inside of the reactor, so that the plate can cover a surface of a natrium cooling material 10. Air bubbles in FP gas exhausted into a cooling liquid go upward and  gather at the top rising along the angular slope of the plate 18, and are exhausted  into a cover gas in a upper plenum 15 after passing through exhaust holes 19. This  causes air bubbles in FP gas to be free from attaching to the plate 18, and thus,  FP gas can be easily exhausted.

Filed: 1981-04-09
Abstract: PURPOSE:To make the intensity distribution of an acoustic wave beam nearly rectangular and uniform in a beam vertical plane by dividing an electroacoustic element in two dimensions, and then driving mutually adjacent electroacoustic element pieces with a 180 deg. phase difference. CONSTITUTION:On an acoustooptic medium 6, a base electrode 7 is mounted, and on it, a piezoelectric diaphragm 8 of LiNbO3 is bonded under pressure with low melting point metal such as Sn, etc.; and a dielectric film is vapor-deposited with a mask, etc., and after an upper electrode 9 is vapor-deposited on the dielectric film, slots 10 and 10', and 11 and 11' are formed with a wire saw, etc. Here, the slots 10' and 11' split the upper and lower electrodes 9 and 7, and the slots 10 and 11 split the upper electrode 9 and the dielectric film 13 only, so applying a high frequency signal to a terminal RF allows split adjacent piezoelectric diapharagms to oscillator with a 180 deg. phase difference. Consequently, the intensity distribution of an acoustic wave beam becomes uniform and even when the light beam is stopped down, the intensity of distribution of diffracted light never deviates from that of a Gauss type, speeding response.

IPC: B24B37/30
Filed: 1986-03-14
Abstract: PURPOSE:To provide processing of a super-flat surface with good productivity by using a pneumatic bearing, and applying restrictive force in the radial direction during lapping between a holder and an outer ring. CONSTITUTION:Compressed air 6 supplied from an air supply port 5 intrudes in a gap (a) between an air supply ring 4 and an outer ring 3, and thereafter is partially led to outside from a' while the rest intrudes in a gap (b) between the outer ring 3 and a holder 2 from a nozzle 7 furnished at the outer ring 3 to be then released to outside. This causes the holder 2, outer ring 3 and air supply ring 4 out of contact from one another, and further, the nozzle 7 is located in the position dividing the outer ring circumference equally, so that it is difficult for the holder to displace in the radial direction. This lapping jig is located in a correction ring of a lapping machine, and when the lapping surface board beings rotating, a flange 3' at the bottom of the outer ring 3 comes in contact with the correction ring, and now the outer ring 3 rotates and the holder 2 also rotates. Thus a specimen 1 can be lapped without procession to provide high precision surfaces easily.

IPC: H04J13/00
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To provide an automatic frequency control circuit which reduces an influence of the error of frequency offset to correct the frequency offset with a high precision. SOLUTION: A Δθ estimating part 8 obtains two phase deviations Δθ1 and Δθ2 per bit from a reception signal.
