Title: Controlling method of dc shunt field motor for vehicle
Inventor: WATANABE NOBUO
IPC: H02P7/298
Filed: 1984-07-12
Abstract: PURPOSE:To prevent a current overshoot at starting time while obtaining sufficient stability and adaptability by providing a varying limiter for limiting the variation amount of conduction rate. CONSTITUTION:A feedback controller 13 outputs a feedback conduction rate alpha2 in response to a deviation DELTAI between an armature current command value IC and an armature current 1A. A damping controller 14 subtracts the differentiated value of the current IA by the differentiated value of a capacitor voltage EC and outputs a damping conduction rate alpha3. A feed-forward controller 12 outputs a feed-forward conduction rate alpha1 in response to an armature speed VLC and a filter capacitor voltage EC. A varying limiter 15 limits the varying rate of the conduction rate alpha0 added with conduction rates alpha1-alpha3 to the prescribed value C1 or lower and outputs an armature chopper conduction rate alpha.

Filed: 1980-10-15
Abstract: PURPOSE:To obtain an inverter function having greater noise margin, by constituting a logical circuit with the 1st and 2nd Schottky barrier type field effect transistors, diodes connected to the source and a load resistor. CONSTITUTION:The drain of a Schottky barrier type field effect transistor (TR)11 is connected to a DC power supply 14 via a load resistor 13, the source is to ground via a diode D15 and the gate is to an input terminal 18, repectively. The drain of the TR11 is connected to the gate of a TR12 of the same type as the TR11, the drain of the TR12 is to the power supply 14 and the source is ground via a D16 and a load resistor 17, respectively. An output terminal 19 is led from the connnection point of the D16 and a resistor 17. When a signal V1 at a terminal 18 is at low level, the TR11 is turned off and the TR12 turns on, and an output signal V2 is at high level. When the signal V2 is at high level, the TR11 turns on and the TR12 turns off, and the signal V2 is at low level. Since the TRs 11, 12 are grounded via Ds 15, 16, the amplitude of logic can be taken larger and the noise margin is also increased.

Abstract: PURPOSE:To prevent generation of a sink in the outside of a gasket, by a method wherein a part of an insert member is held by inserting into a groove or a hole formed into the inside of a molding tool and injection molding is performed by extending the other part of the insert member into a cavity space. CONSTITUTION:Window glass 14 is arranged on a fixed position on a bottom force 12. One fringe part 17a of an insert member 17 is held by inserting the same into a groove 12b of the bottom force 12. The other fringe part 17b of the insert member 17 becomes a state where it is extended into a cavity space 15. A top force 13 is put over the bottom force 12 under this state and the window glass 14 is held between the bottom and top forces 12, 13. Mold clamping is performed and a gasket forming material is injected into a cavity space 15 after that. In this instance, since the fringe part 17a of the insert member is held by inserting into a groove 12b of the bottom force 12, it does not happen that positional deviation is generated. After injection, the gasket forming material is solidified through cooling or cured through reaction, the bottom force 12 and top force 13 are broken and the window glass with a gasket is taken out.

Filed: 1985-07-04
Abstract: PURPOSE:To obtain a stable microwave by forming three semiconductor lasers of double hetero structure on the same semiconductor substrate, composing the two in a composite resonator laser to produce the beat of the two outputs from the other third semiconductor laser. CONSTITUTION:An n-type InP layer of sections I, II and an n-type InGaAsP layer 4 of active layer are partly cut to form a composite resonator laser having an internal reflecting surface (d) in the sections I, II, and the section III is used as a resonator. Since the resonator length is long in the sections, adjacent mode is extremely near, a longitudinal mode position is varied by an interval of several Angstrom  order due to the variation in the gain distribution owing to the variation in a driving current, while the section II has a longitudinal mode characteristic having stable variations in the driving current and the temperature. Since the two lasers of the sections I, II are formed on one substrate, a central wavelength is extremely approached, a beam is formed between the two oscillation waves to produce the beam frequency as a stable microwave from the section III.
