IPC: B21C45/00
Filed: 1992-12-01
Abstract: PURPOSE:To improve the productivity in a forging device and to enable the mass-production of a hollow product of a ring material, etc. CONSTITUTION:In a forging method for spreading the outer periphery of a long hollow blank 10 by rolling down from plural direction crossing at the right angle to this axial direction at the same time, a long mandrel 12 is inserted into the heated hollow blank 10. The hollow blank 10 is spread b forging in the condition of inserting the mandrel 12, and after completing the forging, the inserted mandrel 12 is removed by cutting work. By this method, in order to remove the mandrel by the cutting work after forging without considering reuse of the mandrel, the work taking out the mandrel 12 from the forged product is unnecessary. At the time of fitting the mandrel 12 to a manipulator device, the end part of the mandrel can only be held to the manipulator device. The method is released from the fitting work to a mandrel over for the long term, and the productivity of the forging device is improved.

Title: Optical detecting method for gap
Inventor: NAGAI KOTARO
IPC: G01B11/24
Filed: 1992-12-01
Abstract: PURPOSE:To detect a gap correctly by providing a back material which can cover the gap between a pair of to-be-measured objects from the side opposite to the side where the light is projected from an optical sensor. CONSTITUTION:While a part of a gap 7 of works 2, 3 is covered with a back material 6 from below, the light is cast by an optical sensor 1 from above, so that the data as to the surface shape of the works 2, 3 is obtained. Since the light from the optical sensor 1 is positively reflected even at the part of the gap 7 between the works 2 and 3 owing to the back material 6, it becomes possible to stably obtain the sensor data of the surface shape of the part of the gap 7 from which the reflecting light could not be obtained hitherto. Accordingly, the data of the gap 7 such as the length of the gap or the like can be detected correctly.

Filed: 1987-12-18
Abstract: PURPOSE:To reduce the thickness of a pressure-resisting insulator tube by transferring the arc to pressure release holes through an insulating gas in the enclosed space when a current limit element is made in a conductive condition and an arc is generated. CONSTITUTION:In an enclosed space of a pressure-resisting insulator tube 1, a current limit element 1 with the nonstraightness of voltage-current property is accommodated with a specific interval to the inner periphery surface.

Title: Drive circuit for direct current brushless motor
Inventor: ISHIZUKA HIROMI
IPC: H02P6/08
Filed: 1988-12-20
Abstract: PURPOSE:To eliminate rotational variation by connecting a circuit to limit the output of a current control amplifier to desired voltage after stationary rotation, but not in starting, to the output of said current control amplifier. CONSTITUTION:An output limiting circuit 14 is connected to the output of a current control loop and the output of a current control amplifier 8 is clamped to desired potential even if a feedback loop is lost immediately after switching. Thereby a current booster power transistor is not overdriven, therefore, a current reaches to the stationary value without overshoot. The control terminal 15 of the output limiting circuit 14 can be installed so that a motor may be operated at rotational frequency high enough to make the speed induction volt age thereof higher than desired or higher frequency because operating the output limitating circuit 14 from the time of starting excessively increases the power consumption of the power transistor. In starting, the motor is thus accelerated as conventional and reaches to the stationary rotation in the shortest time.

Title: Digital transmission equipment
Inventor: KONNAI SUEO
IPC: H04M11/00
Filed: 1987-12-22
Abstract: PURPOSE:To protect a digital transmission equipment from the impression of an overvoltage exceeding an ordinary available voltage by inserting an overvoltage limiting circuit to the front stage of a DC-DC conversion part. CONSTITUTION:The device is provided with the overvoltage limiting circuit 10 consisting of a bidirection/two-terminal thyristor inserted between feeding paths from connection points 30 and 31 to the DC-DC conversion part 11. In the digital transmission equipment, the bidirectional/two-terminal thyristor 10 is inserted to prevent the DC-DC conversion part 11 from being damaged due to the impression of the overvoltage at the time of impressing the overvoltage on the connection points 30 and 31 with a digital communication line. In other words, even when the multi-connection of constant current sources at a station side is performed and a voltage at the input terminal of the transmission equipment is increased to flow an overcurrent, the voltage drops when it arrives at the break over voltage (VBO) of the bidirectional/two-terminal thyristor, which prevents the device from being damaged due to the impression of the overvoltage.

Title: Residual capacity display for battery
Inventor: HASEGAWA HIROKAZU
IPC: G01R31/36
Filed: 1992-12-02
Abstract: PURPOSE:To perform high frequency updating of the accurate residual capacity of a battery by defining a value, which is obtained by dividing a discharge quantity accumulated value when discharging from charge completion to first alarm detection by a value determined from a residual capacity value at alarm detection, as an updated capacity. CONSTITUTION:By setting a residual capacity to be 10% when a residual capacity alarming means 4 alarms, the frequency of alarming is increased in practical use. Then, the updated accurate capacity of a battery can be obtained from a capacity memory means 9 by dividing a discharge quantity accumulated value when discharging without charging on the way from charge completion to first alarming by 0.9. As a result, high frequency updating of the accurate capacity of the battery is allowed by the capacity memory means 9 to realize a high-precision residual capacity display.

Title: Waterproof and drip-proof device for camera
Inventor: TAJIMA KOJI
IPC: H04N5/225
Filed: 1992-12-02
Abstract: PURPOSE:To obtain a waterproof and drip-proof device for camera without interfering photography due to the attachment of water drip and a stain on a lens cover. CONSTITUTION:An operation to eliminate foreign matters is set in either mode of cutoff, intermittence, or continuance in advance. When the operating mode of a camera main body is set at a (recording) or (recording standby) mode, a transparent lens cover 2 is rotated by being driven intermittently by a lens cover driving motor 4 if the mode is set in the mode of intermittence according to the above setting, and the foreign matters such as the water drip and the stain, etc., attached on the transparent lens cover 2 are eliminated by being wiped by a fixed viper 3. In such a way, power consumption can be saved since the operation to eliminate the foreign matters is performed only when the operating mode of recording or recording standby is set. Also, since not only the wiper 3 but a lens cover 2 side is also rotated when the operation to eliminate the foreign matters is performed, such inconvenience to interfer the photography by covering a photographic lens with the wiper 3 can be prevented from occurring.
