Title: Hermetic compressor
Inventor: NISHITSUJI KAZUICHI
IPC: F04B39/00
Filed: 1978-01-20
Abstract: PURPOSE: To reduce noise of a hermetic compressor without enlarging its size, by fitting a vertically dividing partition to the space of a suction passage and a suction tail pipe to the partition.  
     CONSTITUTION: A motor 4 drives a rotor 11 and accordingly a crank shaft 18 which reciprocates pistons 17A, 17B to introduce refrigerant taken in a hermetic case 1 from a suction pipe 2 into a motor cover 24. The refrigerant passes through a clearance between the stator 10 and rotor 11 and a suction port 11a, and is taken in a space formed by the lower surface of the motor 4 and a partition 26, then reaches the lower space through the partition's suction port 26a and a suction tail pipe 27 and is discharged from a discharge pipe 3 being taken in by the pistons 17A, 17B. The noise produced by the suction system is reduced by the partition 26 and the long suction tail pipe 27 as well.

Title: Method and device for decontaminating radioactive waste
Inventor: HATTORI AKINORI
IPC: G21F9/28
Filed: 1992-01-14
Abstract: PURPOSE:To reduce a product of secondary waste and decontaminate radioactive waste to a well low level, by cyclicly using an abrasive blasted until it is pulver ized to go out of usability, in a dry blast decontaminating method. CONSTITUTION:A radioactive waste 2 is supported within a blast chamber 1. Abrasives such as a cast iron grits are blasted on the surface of the waste 2 in an oblique direction with compressed air supplied from a compressed air source 4 to a nozzle 3. Abrasives recovered after blasting are classified by a cascaded classifier 5 set below the chamber 1. Abrasives pulverized in the extent impossible of using are recovered to a reclaimer 6. The other most of abrasives are sent to a hopper 7, returned again to the nozzle 3 through a circulating path 8, and used to blast. A radioactive concentration of abrasives reaches to a saturated value about a time when the number of circulating times exceeds a certain number of times, and then almost ceases to increase. Thus, the attained surface contamination density of the waste 2 can well be lowered.

Filed: 1987-01-12
Abstract: PURPOSE:To execute focus detecting operation appropriate for each mode by expanding a focus detecting area in a 1st mode for driving a lens to a focusing position based on a focus detecting result and narrowing the focus detecting area in a 2nd mode for executing only focus detection. CONSTITUTION:The titled device is provided with the 1st and 2nd focus detecting means 1, 2 and a focus detecting area based upon the former means 1 is wider than that based upon the latter means 2.

Abstract: PURPOSE:To obtain 3D system stereophonic sound with 2 system amplifiers by connecting a woofer between the output terminals of 2 system power amplifiers with antiphase operation each other and connecting tweeters between the output terminal of each power amplifier and earthing so as to be antiphase each other. CONSTITUTION:An L signal is entered into the plus terminal of L channel CH power amplifier 8, an R signal is entered into the minus terminal of RCH power amplifier 9 and amplifiers 8 and 9 are excitated with antiphase each other. Since an addition signal of L and R is applied to woofer 14 connected between output terminals of amplifiers 8 and 9, the voice output of L+R are generated from woofer 14 as a 3D system woofer. Since LCH tweeter 10 and RCH tweeter 11 which are connected between each output of amplifiers 8 and 9 and earthing respectively are  antiphase each other so as to compensate the antiphase between amplifiers 8 and 9,  therefore, LCH and RCH tweeters are sounded acoustically with the same phase  and they make 3D system stereophonic sound reproducing device available together with woofer 14.
