Title: Drive circuit of light emitting element
Inventor: HARA YUUJI
IPC: H04B10/00
Filed: 1983-12-14
Abstract: PURPOSE:To increase each projected luminous amount by making the light emitting timing of each light emitting element provided in parallel different so as to increase the current amount flowing to one light emitting element. CONSTITUTION:An output from a pulse code generating circuit 6 is inputted to a scan signal generating circuit 8 and a signal having a different scan timing is outputted respectively to a base circuit of the 2nd transistors (TRs) 31-33. Thus, the TRs 31-33 are turned on switchingly sequentially and light emitting elements 11-13 are lighted switchingly. Since only one of the light emitting elements 11-13 is driven at all times in this way, the current amount per element is increased so as to improve the lighting power.

IPC: H01J61/16
Filed: 1994-09-29
Abstract: PURPOSE: To reduce the unevenness of color of the light projected onto a screen from a light projecting device by forming a light diffuse layer in the surface of a light emitting tube of a direct current lighting type metal halide lamp over from a part, which corresponds to the intermediate part between the center of emission inside of the light emitting tube and the tip of a positive electrode, to the negative electrode side end.

Title: Electromagnetic rotating machine
Inventor: IMAI YASUAKI
IPC: H02K29/12
Filed: 1991-09-17
Abstract: PURPOSE:To obtain a small-sized electromagnetic rotating machine, cost of which is reduced, by making the offset component of the change of magnetic field intensity generated by one of two electromagnetic coupling elements installed on the rotor side and the stator side, affecting to the other, to 1ppr. CONSTITUTION:A change by the revolution of a rotor 4 in a magnetic field generated by an FG magnet 2 is detected by a generating wire element 7a. The output signal of the generating wire element 7a generates sixty pulses pre one revolution (sixty ppr) because one hundred and twenty magnetizing inversion is executed to the pattern of the magnet 2. When the generating wire element 7a is disposed within a fan-shaped range at 45 deg. to the whole circumference of the FG magnet 2 because the magnet 2 is offset and magnetized, a rotational position signal can be formed from an offset modulation component. Accordingly, a rotary magnet exclusive for a conventional index and an element for detecting a rotational position can be omitted, thus allowing miniaturization.

Title: Manufacture of semiconductor device
Inventor: TANIGUCHI AKIHISA
IPC: H01L21/288
Filed: 1986-10-02
Abstract: PURPOSE:To prevent a short circuit between electrodes due to the penetration of Au plating by a method wherein, after a resist mask has been provided on a Cr layer, the mask is etched and Au is plated in order to avoid plating the Au on the Cr layer. CONSTITUTION:After an oxide film 2 has been formed on a collector layer 1 and an opening has been made, a base layer 3 and an emitter layer 4 are formed. By making the opening at the oxide film 2, Pt or Cr is evaporated and sintered to form a silicide. Then, a barrier metal 7 (e.g., Ti, W or Cr), Au 8 and Cr 12 are evaporated. By providing resist 11, the Cr layer 12 is patterned. Then, an Au-plated layer 9 is formed, and the resist 11 is removed. Then, by making use of the Au layer 9 as a mask, the Cr 12, the Au 8 and the barrier metal 7 are removed in succession so that an electrode can be completed. Through this constitution, even if the space between electrodes is narrow, a short circuit is not caused between the electrodes because the Cr layer 12 is formed and the Au is not formed on this layer. As a result, the high-frequency characteristic can be improved.

Title: Collision preventing device for self-traveling cart
Inventor: NISHINO SHUZO
IPC: B61B13/00
Filed: 1991-08-23
Abstract: PURPOSE:To surely and automatically stop the self-traveling carts for prevention of collision of them by controlling the stop of the carts based on only the detection signal of a single sensor corresponding to the route type detected by a detector. CONSTITUTION:A straight-travel sensor 3 detects a backward reflecting surface of a preceding cart when the distance between a self-traveling cart 1 and the preceding cart traveling on the same straight-travel route part 14 becomes less than a fixed distance L1. A cart control part 11 gives a stop command to a motor controller 12 based on the detection signal of the sensor 3. Thus a motor 13 stop to prevent the collision of both carts. Meanwhile a right sensor 4 detects the surface 2 of the preceding cart when the distance between the cart 1 and another cart which are traveling on the same curve route part 15 becomes less than a fixed distance L2. Then the motor 13 stops based on the detection signal of the sensor 4. Thus the cart 1 automatically stops before it collides against its preceding cart.

Title: Automatic voltage regulator for three-phase ac motor
Inventor: TANUMA TOSHIHIKO
IPC: H02P9/30
Filed: 1988-09-21
Abstract: PURPOSE:To suppress abnormal phase voltage rise under unbalanced load by providing an unbalance voltage regulating section for lowering the output voltage from a detecting/smoothing section, when a three-phase load is balanced, and feeding the lowered voltage while feeding the output voltage from the detecting/smoothing section as it is, when the three-phase load is unbalanced, between the detecting/smoothing section and a detecting/comparing section. CONSTITUTION:When one phase output voltage is higher than 240V under unbalanced load, a Zener diode DZ3 is turned ON thus turning a transistor Tr7 ON. Consequently, a resistor R5 is shortcircuited and the voltage to be applied onto a Zener diode ZD1 in a detecting/comparing section 7 increases to lengthen the OFF time of transistors Tr1, Tr1' in a field current control section 8 thus reducing the field current flowing through a field coil 3. By such arrangement, output voltage of a main generating coil 2 drops from above 240V down to 220V.
