Title: Manufacture of sm-co magnet
Inventor: YAMADA HIROYUKI
IPC: B22F9/06
Filed: 1985-03-20
Abstract: PURPOSE:To contrive reduction in cost of production of the titled magnet by a method wherein the metal powder, in which Co or a part of Co is replaced with other element, Sm2O3 powder and Ca grains are placed in a retort, and they are reduced by heating under the specific conditions. CONSTITUTION:Inexpensive Sm2O3 powder is used as the Sm which is a component constituting an Sm-Co magnet, and the powder in which Co powder or a part of Co is replaced by Fe, Cu, Zr and the like is used as the metal of the titled magnet. Also, Ca grains are used as the reducing agent for Sm2O3. These mixed materials are placed in a retort, and they are reduced in an Ar gas atmosphere at the temperature range of 1,000-1,300 deg.C. The reduced Sm and the metal powder can not be alloyed at the heating temperature of less than 1,000 deg.C, and when the temperature exceeds 1,300 deg.C, the retort is damaged. The obtained alloy powder is washed with water and dried up as occasion demands, it is fused in an induction furnace, homogenized and pulverized. As low-priced Sm2O3 is used instead of expensive metal and Sm and the magnet is manufactured by performing a consistent process, reduction in cost of production can be contrived.

Abstract: PURPOSE:To provide an efficient vibration type converter power supply for controlling the output in wide range smoothly by so controlling the open or close of the primary winding side switching element as to vary the closed time responsive to the variation of the control input while retaining the duration of the open time constant. CONSTITUTION:The primary winding side switching element 4 of a vibration type inverter for supplying a direct current through smoothing capacitors C1, C2 to a load Rl opens or closes according to the open or close control signal from a control signal generator circuit 6 operating on the basis of a diviation Ed between the output setting voltage Er and the output voltage detected by the voltage drop of the resistor Rs. The circuit of R3-R4-C3 determines the open or close time of the element 4, the charging time of the C3 becomes the closed period of the switching element 4, and the discharge time of the C3 becomes the open time of the element 4. The open period is so set as to become substantially equal constant value of the time duration of initial half cycle of the free running waveform of the bouncing voltage generated from the secondary winding of a stepup transformer 1.

Title: Optical object detector
Inventor: ONO KAZUO
IPC: H03K17/94
Filed: 1983-04-01
Abstract: PURPOSE:To enhance detection resolving power and to exclude the influence of extraneous light by clearing a detection point, by such simple constitution that a light emitting drive current is controlled corresponding to the detection state in a light receiving point. CONSTITUTION:A current flows the LEDLD of the light emitting part and the photo-transistor P of the light receiving part of an optical type matter detector 10 connected to a constant-current circuit 14 in common in a mutually differential manner and, when a part of the light from LEDLD is blocked by matter and the current flowing the transistor P is reduced, a light emitting drive current flowing LEDLD increases and voltage V0 detected by the transistor P is not abruptly changed. On the other hand, when light emitted from LEDLD is further blocked by matter, the brightness of LEDLD is saturated and the voltage V0 detected by the transistor P abruptly becomes large to clear a detection point. By this mechanism, the detection point is cleared by simple constitution, detection resolving power becomes high, the influence of extraneous light is excluded and the enhancement in the accuracy and reliability of an optical type object detector can be achieved.
