Title: Brazing method for metallic material
Inventor: SHIROYAMA MICHIO
IPC: B23K33/00
Filed: 1989-05-11
Abstract: PURPOSE:To execute brazing so that a molten brazing filler metal does not flow down to the lower part by forming in advance many grooves extended in the axial direction on one or both of the outside peripheral surface of an insert end part of a cylindrical metallic material and the inside peripheral surface of a hole of another metallic material into which the metallic material concerned is inserted. CONSTITUTION:A ring-like brazing material 12 is fitted in advance into a large diameter part formed in the part of a main pipe 2 insert side in a through-hole 9 of a throttle body fitting body 6. Also, on the outside peripheral surface of an insert end part 2a to the hole 9 of the fitting body 6 of the main pipe 2, many grooves 13 and projecting lines 14 of prescribed length extended in the axial direction are formed in advance alternately in the peripheral direction. Subsequently, the end part 2a of the main pipe 2 is brought to press fitting into the large diameter part 9a of the hole 9, and a combined body of the main pipe 2, a branch pipe 5, the fitting body 6 and a connecting member 7 is put into a furnace, and heated in an N2 gas atmosphere or a vacuum atmosphere by using a chlorine compound flux. Next, each connecting part containing the main pipe 2 and the fitting body 6 is brought to brazing in the lump. As a result, it is prevented that a molten brazing material flows down as mentioned above, and the generation of a fillet in the upper part of a joint part of two metallic materials is prevented.

Title: Dropping-type mole-catching device
Inventor: YAMASHITA YOSHITO
IPC: A01M23/20
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a dropping-type mole-catching device enabling mole to invade from both sides, capable of catching mole by utilizing the impetus of the mole and made of a mechanism friendly to nature without causing a dangerous accident, since any measures have not been taken against the damage of crops due to moles until now. SOLUTION: When the channel of a mole is broken, the mole again proceeds while confirming whether its passage is the trail of its channel or not. Since space is formed around hanging plates 3 and the mole cannot proceed while drilling without mounting the bottom plate 4, soil pushed out forwards makes the plate 3 move in the direction of the center and the bottom plate 4 is unfastened and falls together with soil, and the mole can be caught alive.

Title: Kotatsu (foot warmer) in frame work
Inventor: KURIYAMA TAKESHI
IPC: F24C7/04
Filed: 1981-07-28
Abstract: PURPOSE:To allow to put a table plate fixedly on a Kotatu main body without being restricted its setting direction by a method wherein a circuit, which connects over the wireless with the variable resonance circuit of the table plate and controls the energizing to a heating element by detecting the state of resonance of said variable resonance circuit in regard to voltage, is provided in the Kotatu main body. CONSTITUTION:The circuit, which controls the energizing the heating element 9 by detecting the state of resonance of the variable resonance circuit 10 equipped in the table plate 12 and operated by means of an operating unit, is provided in the Kotatu main body 11. When the oscillation frequency of a voltage controlling oscillation circuit 1 nears the resonance frequency f0, the impedance of a circuit 10 rises and the output of a detector 4 lowers. When the output of the detector 4 drops below the reference voltage VD, the output of a comparator 5 turns to be low level, resulting in discharging capacitors C in order to lower the oscillation frequency of the circuit 1. On the contrary, when the oscillation frequency lowers, the capacitors C are charged by reversing the operation as described above in order to raise the oscillation frequency of the circuit 1. Consequently, the voltage across the capacitors C is kept constant, resulting in allowing to keep the temperature in the Kotatu constant by means of a power controlling circuit 8 and the like.

Filed: 1978-09-29
Abstract: PURPOSE: To promote evaporation and mixing by providing near the inlet of an evaporation chamber a plate so slanted as to make the outlet width smaller toward an outlet and providing near the outlet of the chamber a hole opening into a mixture gas passage communicated with a combustion chamber.  
     CONSTITUTION: A liquid fuel sprayed onto an evaporation pan 13 is heated to evaporate by a heater and mixed, in an evaporation chamber 4, with the primary air 5a flowing in from around a nozzle chip 12. Above the pan 13 is provided a slant plate 14 so slanted as to make the outlet width smaller toward an outlet; therefore, a vena contracta develops and a first-stage mixing with air takes place. The mixture gas having undergone the first-stage mixing is expanded on passing through the narrow portion of the slant plate 14, subjected to a second-stage mixing with the mixture gas flowing in constantly in front of a hole 15, and is turned into a vena contracta again at the hole 15. The mixture gas having undergone the second- stage mixing is expanded on passing through the hole 15, and subjected to a third- stage mixing before reaching a mixture gas passage. Thus, mixing is promoted.

SOLUTION: A used lithium-manganese battery is roasted at 500 to 750 deg.C, burnt and organic matters such as graphite and carbon powder of negative active substances are decomposed, burnt and volatilized, and, moreover, CO to form into reducing gas is generated. The obtd. roasted material is pulverized so as to be controlled to about <20 mm by a standard sieve, and again, roasting treatment is executed to the surface of the sieve. The valuables at a plus sieve are magnetically selected, and iron in a battery case as the magnetic material is separated from nonmagnetic material. A minus sieve is composed of the powder of carbon, copper, aluminum, manganese or the like mechanically adhered to iron, and copper is recovered from the minus sieve. By roasting the battery, the weight reduces, and the load of the crushing reduces.  The recovered iron is small in the intrusion of Mn and high in purity, so that it can be used as all iron sources.
