Title: Production of permanent magnet powder
Inventor: HIROZAWA SATORU
IPC: H01F1/059
Filed: 1991-05-20
Abstract: PURPOSE:To easily produce the permanent magnet powder which has a high coercive force and can be easily handled by coarsely grinding a cast ingot having a specific compsn. consisting of a rare earth element, Fe and C to specific grain sizes and subjecting the ground grains to a specific H2 treatment to form powder, then subjecting the powder to a specific nitriding treatment. CONSTITUTION:The cast ingot consisting of 9 to 12at.% R (R is the rare earth element contg. >=30% Sm), 88 to 91% T (T is Fe or <=50% thereof is substd. with Co and Ni) and 0.1 to 5% C is coarsely ground. The cast ingot is preferably roughly ground after the primary crystal phase of the Fe group is decreased to <=20vol.% by subjecting the cast ingot to a soln. heat treatment for 1 to 100 hours at 800 to 1200 deg.C at this time. The roughly ground powder is 50 to 500mum average grain sizes. This powder is heated and held for 30 minutes to 8 hours at 500 to 900 deg.C in 0.1 to 10atm gaseous H2 and is then subjected to a de-H2 treatment. The powder having 0.05 to 0.5mum average crystal grain sizes is thereby formed and thereafter, the powder is held for 30 minutes to 6 hours at 350 to 650 deg.C in 0.5 to 50atm gaseous N2. The permanent magnet powder consisting of the hyperfine crystals having about >= 6kOe coercive force is obtd. in this way.

Title: Amplifier circuit
Inventor: MARUTA MASARU
IPC: H03F3/34
Filed: 1984-07-13
Abstract: PURPOSE:To attain amplification at a low voltage by providing a current source applying a current having a relation with a collector current of an input stage transistor (TR) to a base of an output stage TR. CONSTITUTION:The current source is formed by a current mirror circuit comprising TRs 7, 8 having equal emitter area. Then a current equal to the collector current of the input stage TR9 is fed to a base of the output stage TR10. Thus, the current amplification factor IC/IB is nearly equal to the product of the current amplification factor of the Darlington circuit. Since the operating voltage is a base-emitter forward voltage drop VBE9, the amplification at a low voltage is attained. In replacing the TRs 7, 8 into TRs 15, 16 having the emitter area ratio of 1:n, the current amplification factor is increased to a multiple of (n).

Filed: 1977-12-07
Abstract: PURPOSE: To suppress an instantaneous voltage drop of a generator low at a load throwing in time by providing an intermediate tap in an armature winding and by connecting a load to this tap only at a time throwing in a load.  
     CONSTITUTION: Providing intermediate taps in an armature winding, a load 10 is connected to each output terminal 3-8 through switches 9a-9c. Also an output voltage is detected by a voltage detecting device 13 through transformers 11 and a switch 12 and feed back to a voltage controlling device 14.

Abstract: PURPOSE:To select an effective operation order for a stacker crane by estimation-calculating operating hours from capability of a stacker crane such as a position, speed and acceleration and operating restrictions, etc., to select an operation pattern of the shortest operating hours. CONSTITUTION:When an object to be handled arrives at a warehousing station 4, a shelf for storing it is determined depending on the type of the object, and when three pieces of the objects, which correspond to the number of forks, are accumulated at the warehousing station 4, a stacker crane 2 admits them in. At this time, an object A is to be stored on a storing shelf (a), an object B is to be stored on a storing shelf (b) and an object C is to be stored on a storing shelf (c), while estimated time required for the storage to be completed onto the each shelf is calculated from running speed, lifting speed, acceleration, restrictions, etc., with regard to six cases which correspond to all of the shelves. Thus use of a route of the shortest time can permit the most effective operation. In the case of the next shipment, a route of the shortest time is selected under the conditions similar to the warehousing.

Title: Safety system for robot device
Inventor: KOBAYASHI AKIO
IPC: B25J19/06
Filed: 1992-05-13
Abstract: PURPOSE:To improve the safety of a robot system by disabling the operation of the robot device unless the operator carries an identification card. CONSTITUTION:When the operator approaches a raw material transfer robot 2 carrying an identification card 100, the card 100 sends an identification code 101 to the robot 2 and this signal is received by a power supply allowance unit 24. The unit 24 then decodes the identification code 101 contained in the signal sent. If the unit determines that the code 101 is correct, power supply to the raw material transfer robot 2 is allowed. Then, when the operator turns the power on, the raw material transfer robot 2 starts operation. Therefore, this system is safe because the raw material transfer robot 2 does not operate even if an attmpt is made to use a power supply key to operate a power board, unless the operator carries the identification card 110.
