Title: Defect inspecting device
Inventor: NAITOU SHIMON
IPC: G01N21/90
Filed: 1987-05-09
Abstract: PURPOSE:To detect the defect of the side part of a bottle by measuring the solid shape of the flank of the mouth part of the bottle repeatedly while rotating the bottle on an axis, and comparing adjacent positions. CONSTITUTION:This inspecting device consists of a slit light source 8, a television camera 2, an image processor 3, a rotating device 9, etc. Parallel sheet type incident light 6 from this light source 8 which is parallel to the rotary axis of the bottle 4 is made incident on the side part of the bottle 4 to be inspected at a specific angle.

Title: Boundary detector for automatically traveling working truck
Inventor: YOSHIMURA SHINGO
IPC: G05D1/02
Filed: 1987-05-09
Abstract: PURPOSE:To prevent suspension of a working truck during automatic traveling, by inputting detected information of a normal sensor instead of detected information of a sensor having caused an accident to a boundary detecting means when the accident is found by a sensor disorder detecting means. CONSTITUTION:Detection or a sensor disorder is judged depending upon a sensor disorder signal outputted from a signal treating circuit 15. When one of a pair of light sensorS S1 and S2 has an accident, whether the sensor has caused the accident is in a untreated working side or not is judged. When the sensor is in the untreated land side, the sensor is judged whether the sensor is inside or outside with respect to a truck and the detected date of the sensor having caused the accident are replaced with detected data of a normal sensor.

Title: Anti-backlash drive device for rotor
Inventor: KIMURA TAKASHI
IPC: H02P5/60
Filed: 1982-06-28
Abstract: PURPOSE:To obtain an anti-backlash drive device of an antenna which has less delay of detecting a malfunction by providing a malfunction detector which detects the occurrence of the malfunction of a rotor drive circuit and turns OFF the drive circuit. CONSTITUTION:Since the armature currents IM1, IM2 of motors 4, 5 are, when an antenna 3 is normally driven, in any of I ;IM1>0, IM2<0, II;IM1>0,  I M2> 0, IM2>0, III;IM1<0 and IM2<0 and IM2<0, the relationship of IM1<-h (reference signal), IM2>h cannot be obtained, and the relay 3 is not operated. On the other hand, when the antenna 3 is not normally driven and becomes IM1<-h, IM2>h, a relay 31 is operated, its contacts 31a, 31b intercept the energy to be supplied to the motors 4, 5. In this manner, a malfunction detector 22 detects the malfunction of the drive circuit 1, and when an overload is applied to the antenna 3, the motors 4, 5 are immediately deenergized, thereby preventing the load from being damaged.

Title: Laser diode
Inventor: HASE NOBUYASU
IPC: H01S5/042
Filed: 1983-06-22
Abstract: PURPOSE:To facilitate the formation of a large scaled monolithic optical IC including the title element by a method wherein two electrodes, i.e. a P-electrode and an N-electrode, are formed on the same flat plane. CONSTITUTION:The InGaAsP stripe laser diode has the construction of the P- electrode 8 and N-electrode 103 on the same flat plane by utilizing a buffer layer 2 as the current path. A current impressed between the electrodes 8 and 103 leads from the electrode 8 through a Zn diffused region 7 and an active layer 3 then to the buffer layer 2. Here, the current passes through the layer 2 to a conduction region 102 and then to the electrode 103, when laser oscillation is generated in the active layer 3, resulting in light emission. In this case, the current does not directly interconnect the regions 7 and 102 because of the interposal of an insulation region 104 between the electrodes 8 and 103.

IPC: B23K9/073
Filed: 1990-04-28
Abstract: PURPOSE:To prevent the generation of excessive overshooting at the time of changing over characteristics and to reduce the generation of spatters by initializing a lag module of an error amplifier to a predetermined value in each initial stage of changing over constant voltage characteristic and constant current characteristics. CONSTITUTION:When an electrode 6 and a workpiece 7 are short-circuited, an arc state detection signal Sa is made to a low level and an analog switch SW1 of an initialization circuit 17 is opened and an analog switch SW2 of an initialization circuit 18 is closed. Consequently, the output of the error amplifier 13 is changed according to a time constant determined by the lag module of the error amplifier 13 of the initialization circuit 17. When the short circuit between the electrode 6 and the workpiece 7 is solved, the output voltage V0 increases and the output Sa of an arc state detector 10 is made to a high level and a changeover circuit 15 returns to its original state. At the time, the switch SW1 of the initialization circuit 17 is opened and the switch SW2 of the initialization circuit 18 is closed. Accordingly, at the time of each changeover from the arc generation to the short circuit or from the short circuit to the arc generation, excessive overshooting is not generated on the output voltage and current.
