Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To directly treat the surface of incombustible material contaminated with radioactive element and the like or formed with an oxide layer, without braking it and the like. SOLUTION: In removing the redioactive element in an incombustible material contaminated therewith, the contamination material of the element is transformed into a volatile material by a vapor phase chemical reaction and is is separatively removed of finish the treatment of the material. The reaction is a carbonylation reaction and/or fluorination reaction. In removing the oxide layer from the incombustible material with the oxide layer, the treatment is made under super critical state of reactive gas to finish the surface of the incombustible material. In removing the oxide layer and radioactive element from the incombustible material with the oxide layer, the super critical treatment and carbonylation and/or fluorination treatment are in order or simultaneously applied to finish the surface of incombustible material.

Abstract: PURPOSE:To manufacture a high-density RCo5-type sintered alloy magnet excellent in magnetic properties, by allowing a green compact prepared by compacting an RCo5-type alloy powder (R means rare-earth element of Y) to occlude hydrogen, dehydrogenating the above in an Ar atmosphere and then carrying out sintering. CONSTITUTION:A powdered raw material composed principally of RCo5-type alloy powder (where R means one or more kinds among rare-earth elements and Y) is compacted. This green compact is held in a hydrogen air flow at the prescribed temp. in a range between ordinary temp. and 200 deg.C for a prescribed period to undergo occlusion of hydrogen. The resulting hydride is subjected to complete dehydrogenation at the prescribed temp. of <=900 deg.C by converting a hydrogen atmosphere into an Ar atmosphere to remove residual hydrogen. By the above procedure, the growth of crystalline grains at the time of sintering is prevented and the configuration of crystal atoms in the above powdered raw material is regularized to improve sintering characteristics. Subsequently, this green compact is sintered in an Ar atmosphere at the prescribed temp. in the range between 1,100 deg.C and 1,200 deg.C. In this way, the RCo5-type sintered alloy magnet excellent in all the magnetic properties of coercive force, residual magnetic flux density, and maximum energy product can be obtained.

Title: Water supplier for automatic ice maker
Inventor: NONAKA HIKARI
IPC: F25C1/24
Filed: 1993-03-24
Abstract: PURPOSE:To achieve elimination of a supply water pump and moreover, constant supply of water to an ice making tray by a method wherein a supply water valve is opened in linkage to supply water in a water storage tank by a fixed amount to a constant amount water storage when a water outlet valve is closed with a drive source and then, the water is supplied to the ice making tray by a head from the constant amount storage. CONSTITUTION:With the power disruption of an electromagnet 29, a water delivery valve 31 opens an water delivery port 30 and a water supply valve 43 closes the upper end opening of a supply water part 42. After completion of the ice making with an ice making tray 22, the ice making tray 22 is turned upside down so that ice falls into a ice storage case to store and when the ice making tray is turned back to the original position, the electromagnet 29 is energized. As a result, a valve rod 33 moves upward by a magnetic attraction force of the electromagnet 29 with a magnetic body 36, causing the delivery valve 31 to close the delivery port 30 while the supply water valve 43 is pushed up to open the upper end opening of the supply water port part 42. Thus, the water in a water storage tank 40 flows out into the constant amount water storage device 25 through the supply water port part 42 and is stored in the constant amount water storage device 25.

Abstract: PURPOSE:To obtain a circuit applicable to many kinds of applications, by providing a differential amplifier having symmetrical input terminals, grounding one of the two input terminals, summing an input signal to be compared and a reference signal for comparison and inputting the sum to the other input terminal. CONSTITUTION:A voltage from a Zener diode 28 is a reference voltage inverted for the polarity, and an output terminal 29 is extracted from the output by grounding one of the two input terminals of the differential amplifier 21, e.g., the inverting input terminal. The values of resistors 23, 25 and a variable resistor 22 is set so that the sum between the reference signal (voltage) for comparison obtained at a Zener diode 28 and the input signal (voltage) to be compared obtained between input terminals 24 and 27 is zero, that is, the potential at the non-inverting input of the differential amplifier 21 is 0V. Thus, if the input signal to be compared deviates from the reference signal for comparison, a level difference is caused between the two input terminals of the amplifier 21, and the differential output is extracted at an output terminal 29 as an error signal.

Title: Test method for multi-port ram
Inventor: NAKAMURA KAN
IPC: G06F12/16
Filed: 1987-03-18
Abstract: PURPOSE:To ensure a sure test for multi-port RAM by changing the position values of (n) pieces of bits of an address register for each port. CONSTITUTION:When the value of the lowest order bit of an address register 1-0 in a port 0 is set at 0, the address 0, 2, 4- are allocated to the side of the port 0. When the lowest order bit of an address register 1-1 is fixed at 1, the addresses 1, 3, 5- are allocated to the side of the port 1. Under such conditions, the tests are started at both ports 0 and 1. Thus different test patterns are given from both ports for each port with bits kept fixed. As a result, even the interference occurring between bits can also be checked on a memory plane.

Filed: 1994-03-10
Abstract: PURPOSE:To reduce the cost and to provide listener with a sound of well- balanced sound quality by attacking speaker box to a attaching board, arranging this attaching board on the lower side of a rack and installing a speaker toward the listener. CONSTITUTION:The attaching board 8 is provided with slits or Saran (R) nets, etc., and is fixed to the front plate part 9 in the lower part of the rack 7 toward a player. The mid- and low-compass speakers 4 and speaker boxes 3 are directly attached and fixed to this mounting board 8. As a result, the weight of the speaker 4 is held by the attaching board 8 and is, therefore, stabilized. The speaker box 3 merely covers the speaker 4 and does not receive load and is, therefore, formable to have a smaller thickness and lighter weight. The speaker box made of resin is sufficiently usable as well. Since the mid- and low-compass speakers 4 are installed toward the listener, the sounds of the mid-compass components having high directivity are directly supplied to the player and the listener and, therefore, the good-quality sound is offered to them with the good balance without insufficiency.
