Filed: 1985-06-19
Abstract: PURPOSE:To suppress surely overshooting of an output voltage by providing a current by-passing path that clamps voltage between base and emitter to below fixed voltage when output voltage dropped largely and voltage between the base and emitter of a transistor of phase dividing stage is going to rise up. CONSTITUTION:A current by-passing path involving voltage drop is provided from the base side of a bipolar transistor Q 3 of phase dividing stage 2 to the output (out) side of an output stage 1. Magnitude of voltage drop in the by-passing path is set to become smaller than voltage drop generated in a path from the base of the bipolar transistor 3 of a phase dividing stage 2 to negative side of a power source, i.e. grounding side through the emitter. The current by-passing path is constituted of two diodes, pn connection diode D1 connected in series in normal direction and a Schottky barrier diode D2. Accordingly, the magnitude of voltage drop Vf 1 in the current by-passing path goes to the sum of voltage in normal direction Vf (D1), Vf (D2) of diodes D1, D2 respectively.

Filed: 1980-09-22
Abstract: PURPOSE:To diffuse a sheet resistor between lots of a wafer with less irregularity by exposing and using fresh surface at every predetermined number of times of a solid diffusion source. CONSTITUTION:As the number of uses of a solid diffusion source increases, the volatile amount of impurity decreases. Accordingly, the sheet resistance rhos of the wafer will decreases. When the surface of the solid diffusion source is polished when it is lowered to the prescribed degree to expose new surface and reuse it, it is so diffused as to approximately maintain the sheet resistance rhos of the wafer always constantly.

Abstract: PURPOSE:To perform control corresponding to the distance to an obstacle only by a pair of a transmitter and a receiver by providing plural detection output circuits which generates outputs corresponding to signal levels to the receiver for a reflection signal from the obstacle. CONSTITUTION:A signal sent by the signal generator 1 impinges on the obstacle and returns as the reflection signal B having a level corresponding to its distance. This signal B is received by the receiver 2 and converted into an electric signal, which is passed through a filter circuit 5 to remove its noise and then sent to a high-level detecting circuit 4 and a low-level detecting circuit 5. When the obstacle is nearby and the signal level is high, both the high-level detecting circuit 4 and low-level detecting circuit 5 detect the signal and both a high-level output circuit 6 and a low-level output circuit 7 output signals. When the obstacle is distant and the signal level is low, only the low-level detecting circuit operates and the output circuit 7 sends out a signal. The detection corresponding to the distance is performed by one obstacle detection sensor.

Title: Method for preventing caking of particulate material
Inventor: EBARA AKIRA
IPC: B01J2/00
Filed: 1984-06-29
Abstract: PURPOSE:To avoid the caking of a particulate material easy to cake by uniformly adhering a slight amount impurities adhered to the particulate material to the surface thereof to prevent the direct contact of particles, by applying stirring treatment to the particulate material prior to storing or packing said particulate material. CONSTITUTION:Stirring treatment is applied to a particulate material easy to cake such as an inorg. substance, for example, salt or magnesium chloride, an org. substance, for example, urea and foods or food materials prior to storing or packing the particulate material. In this case, stirring is not limited to a usual concept for performing stirring merely by a stirrer and, for example, stirring treatment, such that the particulate material is allowed to fill a drum and stirred by a screw, may be taken. By this method, in an angular particulate material, friction action is generated between particles by stirring treatment and corners of the particulate material are slightly rounded off and the pressure at the contact points between particles are markedly reduced and caking is hardly generated.

Filed: 1984-06-29
Abstract: PURPOSE:To prevent central segregation by rolling down continuously a billet while subjecting a pair of rolls to the repetition of the reciprocating motion to draw gradually the billet in the casting direction. CONSTITUTION:The billet 1, supported by supporting rolls 5, is rolled down by a pair of billet hold-down rolls 6 near the point where the solidification is completed while the rolls are moved back and forth respectively by hydraulic cylinders 7.

IPC: B41M1/40
Filed: 1986-06-09
Abstract: PURPOSE:To prevent the thickness of a coated film from being made excessive and to prevent the generation of coating failure by regulating a rotated and driven coating roller freely far and near from/to the circumferential surface of the drum of electronic parts and separating the roller from the electronic parts when the transfer of an endless belt is reduced and stopped.

Title: Gain control circuit
Inventor: ENDO TOSHIO
IPC: H03G3/10
Filed: 1985-06-19
Abstract: PURPOSE:To control unequivocally the gains of plural amplifier circuits by means of a microprocessor by connecting mutually sources of dual FETs, changing a gain control voltage to control a current flowing to one FET. CONSTITUTION:RQ1, RQ2 represent the equivalent resistance of the FET of left and right halves of the dual FETQ2'. An operational amplifier IC represents an operational amplifier or an integration circuit using an operational amplifier. A potential VA at a point A is equal to a control bias voltage VS by the action of the operational amplifier IC. Since the collector current of a transistor (TR) Q1 depends on the equivalent resistor RQ1 of the dual FET Q2', the current I depends definitely on the FET control bias voltage VS. Thus, the gain of the amplifier is decided unequivocally by the control voltage VS.
