Title: Zero position regulating method of robot
Inventor: MUKAI YASUSHI
IPC: G05B19/18
Filed: 1992-05-14
Abstract: PURPOSE:To provide a zero position regulating method that is relatively inexpensive and promotes automation so easily by making a direct measurement of a tilt angle and an inclined direction to the gravitional direction of each turning center shaft in respective articulations, performable without receiving any effect of machining accuracy in an arm structural member and so on, and actualizing a highly accurate regulation simply, while regulating plural pieces of articulated shafts with a single sensor. CONSTITUTION:A tilt angle sensor 3 detecting a tilt angle 7 to a gravitional direction G is secured to a robot arm A, while the tilt angle gamma is measured by the sensor 3 as rotatively operating a rotating articulated shaft J4 one by one with a robot controller, and a tilt angle alpha and a tilting direction to the gravitional direction of another articulated shaft J3 are calculated from information of a turning angle gamma of the obtained articulated shaft J4 and another information of the tilt angle gamma. Each zero position of respective articulations is regulated successively accordingly with the gravitional direction G being used as a criterion.

Title: Formation of functional thin tin film
Inventor: FUSHIMI MASAHIRO
IPC: C03C17/09
Filed: 1986-05-28
Abstract: PURPOSE:To form a flat and uniform thin Sn film on a substrate surface by converting a gaseous mixture composed of raw material SnCl4 and reducing agent H2 to plasma and reducing a gaseous raw material at the time of forming the thin Sn film on the surface of the substrate having steps by a CVD method. CONSTITUTION:The inside of a reaction vessel 2 contg. a pair of electrodes 3 consisting of the electrode connected with an electric wire 4 for throwing of high-frequency electric power connected to a high-frequency power and the grounded electrode and the substrate 5 set on a substrate susceptor 6 contg. a heater is evacuated to <=10<-5>Torr reduced pressure by a discharge pipe 7 connected to a rotary pump. The raw material SnCl4 is then bubbled with an inert gas such as He to form gaseous SnCl4 which is introduced by a carrier gas such as He mixed with the reducing agent gaseous H2 from a supply pipe 1 into a reaction vessel 2. The plasma is generated by impressing a high-frequency voltage of 13.56MHz to the electrodes 3, 3 to reduce the SnCl4 with the H2, by which the uniform and flat thin Sn film is formed on the surface of the substrate 5 having the steps.

Title: Actuator for throttle valve of fuel feeder
Inventor: TAKAYAMA TERUO
IPC: F02D41/08
Filed: 1980-09-03
Abstract: PURPOSE:To enable smooth screw transmission in an actuator for opening or closing an automobile throttle valve, by causing a restoring force when a gear slips due to the protrusion of the actuator. CONSTITUTION:A compressed spring 18 is provided between an output shaft 7 and an outer shell member 14. The torque of a DC motor 8 is transmitted to a third gear 15 through a gear train to protrude the output shaft 7 through the threaded part 17 of the gear 15 against the force of the compressed spring 18. The spring 18 acts to push the output shaft 7 toward the third gear 15. The pushing force of the spring 18 becomes maximum when screw transmission fails. When the DC motor 8 is reversed, threaded parts 16, 17 are engaged with each other again to pull the output shaft 7 back. The reengagement is smoothly effected because the restoring force of the spring 18 acts.

Title: Instrument and method for magnetic permeability measurement
Inventor: YONEDA YOSHIROU
IPC: G01R33/16
Filed: 1990-05-14
Abstract: PURPOSE:To reduce the measurement error of high frequency by inserting a coil for gain measurement into a measuring circuit and correcting a value of magnetic permeability with a measured transfer function. CONSTITUTION:Only when a signal source changeover switch 8 is placed on the side of the coil 7 for gain measurement and a sample to be measured is inserted into a magnetic flux detection coil 2, a detection coil changeover switch 4 is switched between a magnetic field detection coil 3 and the coil 2 to supply a signal to an input terminal 9. The ratio of outputs of an output terminal 10 in those cases is found. Then the ratio of outputs is fond similarly without inserting the sample to be measured into the coil 2. Further, the switch 8 is switched to the side of a coil 1 for AC magnetic field generation and the ratio of outputs when the sample to the measured is inserted into the coil 2 and not inserted is found similarly. Those four ratios are substituted in a specific equation to find corrected magnetic permeability, thereby reducing the measurement error.

Title: Exchange control system
Inventor: KAIYAMA AKIRA
IPC: H04M3/00
Filed: 1983-07-04
Abstract: PURPOSE:To obtain high profitability and high reliability by clearing information related to a call when a repeating exchange is in communication, and after the completion of the communication, disconnecting the connection line by information from a preceding exchange or a following exchange. CONSTITUTION:A subscriber's exchange LS transmits a call signal to a signal transmission/reception part 3 in the repeating exchange TS. The transmission/reception part 3 transfers the calling signal to a communication line connection control part 4. The control part 4 connects the communication line and then accumulates the call signal in a call information accumulating part 5. Then the control part 4 outputs an instruction for transmitting a call confirming signal with call information to the transmission/reception part 3. Receiving said signal, a transmission/reception part 1 accumulates the call information of the TS in a call information accumulating part 6. Receiving the call confirming signal from the following exchange, the TS clears the call information accumulated in the accumulation part 5. At the time of disconnection, the LS transmits a disconnection signal provided with the call information accumulated in the accumulation part 6 to the transmission/reception part 3. The transmission/reception part 3 controls the release of the communication line. Thus, the system makes it possible to reduce the number of storage circuits.

Abstract: PURPOSE:To obtain a pn junction LED which can emit blue color light with high practical luminous intensity by setting the thickness of light emission layer at a specific value or above. CONSTITUTION:The face having orientation inclining about 5 deg. in the direction of <11-20> on the (0001) Si face is employed as the growing face of a substrate. High frequency current is then fed to a work coil 24 while feeding hydrogen gas into a reaction tube 21 through a gas introduction port 26 thus heating an n-type SiC single crystal substrate 10 at 1400-1500 deg.C and then material gas and impurity gas are fed thereto. A light emission layer 200 of n-type SiC single crystal, a first P type SiC single crystal layer 300, and a second P type SiC single crystal layer 400 for current diffusion layer are formed sequentially on the substrate 10. The light emission layer 200, and the first and second P type SiC single crystal layers 300, 400 are then etched selectively to form a mesa structure. Consequently, light emission mechanism is prominent when the light emission layer of a pair of n-type donor and acceptor is 5mum thick or above thus realizing a pn junction LED having high luminous intensity.
