Title: Apparatus for electron beam lithography
Inventor: TSUJI HIROSHI
IPC: G03F7/20
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for electron beam lithography of which trajectory is not affected by a magnetic field leakage from a permanent magnet used in a guide and drive mechanism of a specimen stage. SOLUTION: A guide mechanism of a specimen stage 16 comprises an air bearing guide, floating over a fixing table 18. The stage 16 is drawn by a permanent magnet 17 toward the fixing table 18 maintaining the stage position. The permanent magnet 17 is shielded by a shield member 21 in order to prevent a magnetic field leakage of the permanent magnet 17 from affecting the position of illuminating the specimen 7 with an electron beam 4. Another shield member 22 is mounted below the electron lens 5 in order to inhibit the magnetic field variation generated above the specimen 7 owing to the movement of the shield member 21 through the leakage. The guide mechanism of the stage is not contacted to prevent any slight distortion of the table member mounting the specimen, so that the stage may be precisely moved to precisely picture the specimen by the electron beam.

Title: Diversity receiving system
Inventor: KOBORI SATOSHI
IPC: H04L1/06
Filed: 1994-12-05
Abstract: PURPOSE: To provide a diversity receiving system which can always ensure a good receiving state of signals. CONSTITUTION: In a diversity receiving system which performs the reception of signals by switching plural receiving paths 1 and 2, the distortion value of detection signals of both paths 1 and 2 are detected. At the same time, the path 1 or 2 that has the least detected distortion value is selected for reception of signals. It is preferable to observe the detection signals in terms of time series to calculate the eye opening and the receiving path where the eye opening is largest is selected. On the other hand, a shift extent is calculated at a symbol point against the prescribed reference value of the detection signal and the receiving path where the shift extent is minimized is selected.  Furthermore, it is desirable to previously select in time division an undetected receiving path and also the distortion value of the detection signal is calculated for the selected receiving path. Then the receiving path where the calculated distortion value is minimized is selected for reception of signals.

Title: Testing method of reflection with high resolution and apparatus therefor
Inventor: HORIGUCHI TSUNEO
IPC: G02B6/00
Filed: 1987-12-01
Abstract: PURPOSE:To realize a testing method of reflection with high distance resolution, by a method wherein a difference between the delay times of a reflected light signal from an optical fiber and a reference light from their emission to reception is adjusted to be zero or a value close thereto. CONSTITUTION:An optical wave divider 2 divides an emission light from a light source 1 into a probing light and a reference light. A light frequency shifter 3 shifts the frequency of the probing light by DELTAf from a frequency (f) of the light source 1, and the probing light is made to enter an optical fiber 5 through an optical directional coupler 4. In this constitution, an optical delay circuit 9 is adjusted so that a beat electric signal by a composite wave formed of the probing light reflected or back- scattered at some point in the fiber 5 and of the reference light be the maximum, and then the optical delay circuit 9 is adjusted so that a belt due to reflection or the like at another point in the fiber 5 be the maximum. When a difference between a delay time for one point and a delay time for another point is denoted by DELTAT and a light velocity in the fiber 5 by V, on the occasion, a distance between one point and another point can be determined by V.DELTAT/2, and a high distance resolution is obtained even by using a light source of which a coherence time is short.

Title: Current limiting device
Inventor: TOUDOORU BAIATSU
IPC: H02H9/02
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To restrain a short-circuit current to be at most the breakdown limit of an electric device or passive elements of a circuit which are to be protected, by connecting a PTC resistor with a parallel circuit to a varistor of a bypass resistor branch. SOLUTION: A bypass resistor branch 6 is connected in parallel with a PTC resistor 5 via a main current circuit. The bypass resistor branch 6 is a series circuit constituted of a varistor 7, an ohmic resistor 8, and a choke or an inductor 30. In the case of an error or a short circuit, the PTC resistor 5 generates heat, and exceeds its response temperature. As a result, the resistance of the PTC resistor 5 is largely increased, and limits a current. A short-circuit current is made to flow in the bypass current branch 6, so that thermal breakdown of the PTC resistor 5 is avoided. Thereby the short-circuit current can be limited within 10μs, i.e., the value lower than or equal to the breakdown limit of an electric device or passive elements of a circuit which are to be protected.

Title: Collision-preventing device for vehicle
Inventor: MATSUDA SHOHEI
IPC: G01S13/931
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To improve the driving feeling of a driver and to easily accept an actuator by changing a possibility-of-collision discriminating level or actuator actuating level based on the lateral relative distance to an object from its own vehicle. SOLUTION: When the lateral relative distance to a preceding vehicle from its own vehicle is calculated 7 from the measured value of a distance measuring unit 1, a collision avoiding level discriminating means 9 sets a collision level discriminating coefficient K at a smaller value as the lateral relative distance becomes longer and a discriminating means 2 changes a reference distance for warning and another reference distance for automatic brake by taking the coefficient into consideration. Therefore, when the lateral relative distance to the preceding vehicle from its own vehicle is long and the collision with the preceding vehicle can be avoided through the steering operation of the driver, the actuating frequencies of an actuator AA for warning and another actuator AB for automatic brake are reduced and the driving feeling of the driver is improved.  When the relative distance is short, on the contrary, the actuators AA and AB are actuated in an early stage so as to improve the driving feeling.

Title: Device for treating radioactive methyl iodide-containing gas
Inventor: MAEDA TAKESHI
IPC: G21F9/02
Filed: 1988-11-29
Abstract: PURPOSE:To remove radioactive methyl iodide by an active carbon filter by using a pitch type active carbon fiber filter and absorbing away the acidic gases and hydrocarbon contained in a radioactive methyl iodide-contg. gas by this filter. CONSTITUTION:The pitch type active carbon fibers 4 are sandwiched by dust removing filters 5 and are bent to a corrugated shape to obtain the pitch type active carbon fiber filter 6. The filter 6 is held by a holder 7 and is mounted to a mounting frame 8. A discharge fan 3 is then driven to absorb away the acidic gases and hydrocarbon from the radioactive methyl iodide-contg. gas past the dust removing filter 1. The radioactive methyl iodide contained in the gas is then removed by the active carbon filter 2 added with a radioactive methyl iodide removing agent. The acidic gases and hydrocarbon of a low concn. are then effectively absorbed away as the adsorption rate of the filter 6 is high. The early degradation in the adsorption performance of the filter 2 is thus averted.
