Title: Protective circuit for pack battery and secondary battery
Inventor: TSUKAMOTO HISASHI
IPC: H02H7/18
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To suppress voltage decrease as much as possible at the time of discharging. SOLUTION: A circuit 15 exclusively for charging through which charging current Ic to a secondary battery 11 flows and a circuit 13 exclusively for discharging through which discharging current Id flows are installed. A FET 16 for preventing overcharging is installed at least in the circuit 15 exclusively for charging of them and the discharging current Id is made to run only in one FET 14 at the time of charging, so that the voltage decease due to the inner resistance of FET is lowered to a half as compared with that in a conventional battery.  Consequently, since the discharging current does not flow in a switching element of the circuit exclusively for charging due to installation of the circuit exclusively for charging, vain voltage decrease by the switching element can be avoided and as a result, high output voltage can be reliably retained even in the case a secondary battery as same as a conventional one is used.

IPC: B09B5/00
Filed: 1994-02-04
Abstract: PURPOSE:To inexpensively and rapidly carry out a treatment operation by processing raw materials into treating materials which are assemblies of compsn. units of small grain sizes, then heating the treating materials in the state of coating these compsn. units with oil at the time of producing useful regenerated resources with various kinds of org. waste as raw materials. CONSTITUTION:The raw materials are first processed into the treating materials which are the assemblies of the compsn. units of the small grain sizes in order to produce the useful regenerated resources with various kinds of the org. waste consisting of residues of fish and shellfishes, vegetable scrap, etc., as a raw material. For example, a crushing and kneading machine 1 is used at this time and the org. waste is fed from a feed port 11 and is rubbed and crushed by stationary struts 12 and rotating blocks 13 and thereafter, the waste is pressurized by a perforated plate 15 and is discharged from a discharge port 14. The treating materials are then heated and dehydrated in the state of coating the compsn. unit with the oil. For example, a heating type agitating and mixing machine 2 is used and rotary vanes 22 mounted at a revolving shaft are rotated while these vanes are heated by the steam injected from the end 23 of the revolving shaft in this time. In the meantime, the kneading machine 1 and the mixing machine 2 may be connected by a rotary valve 3.

Abstract: PURPOSE: To make a lubricant possible to develop an excellent lubrication performance at high temperature range, and to improve the simplicity of the use and the workability of stripping after the forging work, by compounding a specified proportion of boric acid, borax, graphite and molybdenum disulfide to form the titled lubricant.  
     CONSTITUTION: The lubricant is prepared in a state of a water paint by homogeneously kneading 80W95pts.wt. boric acid, 20W5pts.wt. borax, and 25W50pts.wt. graphite and/or molybdenum disulfide against 100pts.wt. the sum of foregoing two components, with water. After applying this lubricant to the surface of forging blank, it is, directly or after receiving a preparatory drying process, heated by the heating furnace; thereby, boric acid and borax are molten together forming a glass state which therein forms a lubricative film. This lubricative film consists of a double layer construction possessing a ceramic coat firmly bonding to the steel surface; since the skin layer is rich in graphite, and the second layer comprises complicated oxides of steel, so that the lubrication effect of such solids as graphite, etc., is effectively displayed to the maximum.

     CONSTITUTION: High frequency pulse current and pure DC generating units 2, 3 receiving control commands Ih 0 , Id 0  from respective current control circuits 4, supply currents proportional to these to an electrode 5 and a work 7 to be welded. Setting devices 4a 1 , 4a 2  of circuits 4 output set points Ih 0 ' and It 0  respectively of high frequency pulse current and total current, and an adder 4b obtains Id 0 '= (It 0 -Ih 0 '), and issues a command Id 0  if Id 0 ' is positive. The potential of point A of code inverting circuit 4d is 0, and an adder 4e delivers Ih 0 ' as Ih 0 . When Id 0 ' is negative, a limiter circuit 4c sets Id 0  to 0, then point A in the circuit 4d becomes positive polarity, so that a command Ih 0 '-It 0  may be obtained. As a result, the adder 4e delivers It 0  as Ih 0 . When Id 0 ' exceeds the pure DC power supply maximum output defining command value Idp, the circuit 4c defines it to Idp.

Consequently, ultrasonic-wave transmitting and receiving timing of vibrators 11, 12... is adjusted through timing signal generator 8 corresponding to time response characteristics due to variance of element parts. On the other hand, computer 11 controls high-speed sampling circuit 6 after reception corresponding to the delay time that corresponds to time response characteristics to perform high- precision ultrasonic flaw detection by interference without selecting parts characteristics rigidly. In addition, when both receiving timing and transmitting-receiving timing are adjusted, the same results is obtained.
