Title: Internal pressure explosion-proof mechanism
Inventor: ONISHI KEN
IPC: B25J19/00
Filed: 1993-06-02
Abstract: PURPOSE:To simplify a wiring system or the like by making common use of an electric wire of a solenoid valve to open and close an exhaust hole of an external frame and an explosion-proof object apparatus when infiltration of flammable gas is prevented while maintaining the inside of the external frame to shield the explosion-proof object apparatus in a high pressure condition. CONSTITUTION:When painting work is carried out by a robot 1, since explosive gas happens to generate from paint or the like, the robot 1 is shielded by an external frame 2. Before the painting work is carried out, explosion-proof work is carried out. That is, a hand valve 61 of an air pipe 60 is opened, and air is supplied inside of the external frame 2 from an air inlet hole 52. At the same time, a solenoid valve 51 is opened, and the air in the external frame 2 is discharged from an exhaust hole 50. When a pressure detector 53S detects that air pressure in the external frame 2 reaches an upper limit value, an electric current is carried to a robot control device 10 or the like by a protective monitoring device 20 after prescribed timer time passed. The solenoid valve 51 is closed, and the air pressure in the external frame 2 is held under high pressure.

Title: Object-position detecting system
Inventor: TAKEUCHI TAKAHIKO
IPC: H04W84/10
Filed: 1990-05-22
Abstract: PURPOSE:To recognize the positions of persons and materials in real time based on transmitted signals which have undergone spectrum diffusing modulation from a data carrier by providing the data carrier wherein a pseudo-random series inherent to many persons and materials, e.g. a gold series, is assigned. CONSTITUTION:Carrier signals are transmitted from a data carrier 10-1 and undergo spectrum diffusing modulation in a gold series G1. The signals are received with a leakage cable 12-2. The frequency of the signal from one end E1 of the cable is converted into a frequency f2 in a frequency converter 16-2. The signal is superimposed on the signal from the other end E2. The signal is sent into a receiving unit 18. In the unit 18, correlation computation of the received signal series and the gold series G1 - Gm is performed by using two frequencies f1 and f2 with respect to the received signals from a transmitting cable 14. A delay time DELTAT between peak values is detected. A distance L1 from the terminating end E1 of one cable is obtained as L1 = (L - DELTAL)/2 based on DELTAT. The data carrier 10-1 can be identified based on the reference gold series used in the correlation computation when the correlation peak values are obtained in the receiving unit 18.

Title: Reticle
Inventor: KUSANO YASUSHI
IPC: G03F1/42
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To measure the overlapping accuracy of an enlarged pattern of a reticle to a wafer with high accuracy by constituting a measuring pattern in such a manner than the outline of a light-shielding part is axial symmetry perpendicular to the outline of a light-transmitting part or in point symmetry of the light-transmitting part. SOLUTION: The measuring pattern of the reticle consists of a light- transmitting part 17 formed in a light-shielding part 20a and a symmetric light- transmitting part 36 enclosing the light-transmitting part 17 and having a square frame with the same center as that of the light-transmitting part 17. By forming the symmetric light-transmitting part 36, a light-shielding part 37 which is symmetric for the center lines 23a, 23b of the light-transmitting part 17 and forms the outline of the light-transmitting part 17 is formed. The light-shielding part 37 is symmetric around the center P of the light-transmitting part 17. In this constitution, since the thermal expansion of the mark for the measurement of overlapping accuracy is isotropic around the center P, the center P does not move even when the mark for the measurement of overlapping accuracy expands by heat.  Therefore, the overlapping accuracy can be measured with significantly higher accuracy than a conventional method.

Title: Hidden face processing device
Inventor: OKI TAKESHI
IPC: G06T15/40
Filed: 1987-05-28
Abstract: PURPOSE:To perform the hidden face processing and the output of processing results at high speed by providing a token converter to quickly operate a hidden face processor independently of the speed of data input. CONSTITUTION:A hidden face processor 2 and a token converter 1 are provided. Segment information to be inputted to the hidden face processor 2 is inputted to the converter 1 asynchronously, and the converter 1 outputs inputted effective segment information to the processor 2 synchronously with a clock if segment information is complete, and the converter 1 generates effective segment information and sends it to the processor synchronously with the clock if segment information is not complete. Since ineffective segment information is generated and is given to the hidden face processor 2 when segment information is not complete, this hidden face processing device can be independently operated by a very high-speed synchronizing clock even if it is connected to a slow asynchronous system like a host bus, and the system performance is improved.

Title: Design of reactor for solid electrolyte ion-conductor
Inventor: GOTTZMAN CHRISTIAN FRIEDRICH
IPC: B01J19/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To conduct an effective ion-conductor reaction in a gas separation system by a method wherein heat generated from a reactant gas flow reacting with oxygen transmitted through an ion-transporting membrane is transferred to a feed gas flow to heat the feed gas flow and temp of the ion-transporting membrane is allowed to be held within an operational range of the ion- transporting membrane. SOLUTION: An oxygen-contg. gas flow 18 enters into a shell 14 at proximity to the top of a reactor and flows downward in a cross countercurrent against a stream of reactive purge gas inside an ion-transporting pipe 1 directed by a deflector 4 or the flow of a reactant gas flow 16 and enters into a ring passage 2 between the ion-transporting pipe 1 and a shroud 3, where oxygen is extracted from the gas flow 18 by being transported radially into the inside via the ion-transporting pipe 1. The gas flow 18 is recovered from a space between a pipe seat 7 and a pipe seat 8 as a gas flow 20 with a decreased amt. of oxygen. The reactant gas flow 16 flows inside the ion-transporting pipe 1 and, while the reactant gas flow 16 passes through the ion-transporting pipe 1, generates a gas flow 22 by a reaction with oxygen atoms, being emitted from the reactor.
