Title: Device and method for automatically measuring density of body
Inventor: AARU POORU GURENBIRU
IPC: G21C17/06
Filed: 1994-02-25
Abstract: PURPOSE: To prevent measuring errors caused by the surface defect of a chip or the like by measuring the weight of an object using a robot device in a dry medium and in a wet medium, and calculating the density of the object according to Archimedes' principle. CONSTITUTION: Air, for example, is used as a dry medium, and distilled water of a known temperature and density as a wet medium. A pellet 1 (object for measurement) on a conveyor 2 is taken out by the fingers 27 of a robot 21 for extracting and placing and is placed on a dry measuring saucer 17 to measure the weight W1 of the pellet 1 in air with a balance. Next, after the pellet 1 is temporarily placed on a plate 31, it is put into water in a tank 7 by the fingers 29 and placed on a wet measuring saucer 19 to measure the underwater weight W2 of the pellet 1. The measurements are input to a CPU, where the density D of the pellet 1 is calculated according to Archimedes' principle using D=(W1 ×d)/(W1 -W2 ). In the formula, (d) is the density of the water.

Title: Leakage flux flaw detecting apparatus
Inventor: FUKUDA SHINICHI
IPC: G01N27/83
Filed: 1993-03-12
Abstract: PURPOSE:To detect a minute flaw on the surface of a cylindrical or circular cylindrical magnetic material transferred in the axial direction and reduce areas left without being detected, by holding both sides of a looped magnetic coil by a sensor holder and arranging a sensor zigzag at the inner peripheral face of the sensor holder. CONSTITUTION:An exciting current generated at an exciting current source device 10 is supplied to a looped magnetic coil 3 held by a sensor holder 4, thereby to form a high-density magnetic field 2 at the surface of a to-be-inspected material 1. The magnetic field 2 generates a leakage flux 8 at a part of a surface flaw 7. The leakage flux 8 is detected and converted electrically when the to-be-inspected body 1 is positioned immediately below a sensor 5 set at the inner peripheral surface of the sensor holder 4. Flaws of a tubular end 9a and a tubular end 9b are detected respectively by a sensor 5a in the rear stage and a sensor 5b in the front stage, whereby areas left without being detected are reduced. A surface flaw detecting signal is amplified at 11, from which noises are removed by a filter 12. After the waveform of the signal is shaped at 13, the signal is recorded at 14. A signal not lower than a predetermined level is extracted by a comparator 15, compared with a reference value at 16, so that the to-be-inspected material 1 is evaluated.

Title: Magnetic guidance system for vehicle
Inventor: SATO SHUN
IPC: G05D1/02
Filed: 1989-03-06
Abstract: PURPOSE:To simplify the constitution of a driving controller and to improve the automatic driving stability for a vehicle by adding a single dislocation detection coil having the winding surface of a winding set in parallel to a magnetic mark as well as the winding surrounding a magnetic field generating means to a magnetic sensor 3. CONSTITUTION:The magnetic field generating means 4 of a magnetic sensor 3 receives an exciting signal and produces a spatial magnetic flux via the magnetic poles of both ends. This magnetic flux forms a magnetic flux distribution responding with the dislocation of a vehicle 1 to a magnetic mark 2 and turns toward this mark 2. Then the spatial magnetic flux interlinks the winding of a single position error detection coil 5 which surrounds the means 4. Then the vehicle 1 has the dislocation and the sensor 3 gets out of the center of the mark 2, the magnetic flux distribution is asymmetrical to the center of the mark 2 and interlinks asymmetrical the coil 5. Consequently, a dislocation detection signal is produced at the coil 5 and the extent and the direction of the dislocation of the vehicle 1 is detected to the mark 2. In such a manner the constitution of a control circuit is simplified and the driving of the vehicle 1 is controlled with high accuracy.

Filed: 1986-03-11
Abstract: PURPOSE:To prevent the malfunction of a circuit due to an erroneous input by constituting the capacity of a pulling side to the size of the capacity or above of an active side to exist respectively between an input line and the power source line of the mutually different active side and pulling side. CONSTITUTION:Concerning respective capacity values of a capacity Cp of a pulling side and a capacity Ca of an active side, so as to come to be the relation of Cp>=Ca, an electrode is provided through a dielectric object between the transparent plates of a liquid crystal displaying panel and a capacity is formed. When an electric power source voltage V2 is quickly increased to V2(t0) for a time t0 by a noise, a threshold voltage VT=V2/2 of a circuit 4 is changed to VT(t0)=V2(t0)/2 and an electric potential V3=V2 of an input line 3 is changed to V3(t0)=V2+{V2(t0)-V2} and Cp/(Ca+Cp). When the relation of respective capacities is Ca<=, an electric potential V3(t0) of the input line 3 does not always arrive at a threshold voltage VT(t0) of the above-mentioned circuit 4, and it can be prevented that the erroneous input is obtained.

Title: Exhaust pipe and vacuum unit and semiconductor manufacturing device using it
Inventor: JINBO TAKESHI
IPC: F16K31/36
Filed: 1988-03-09
Abstract: PURPOSE:#?To enable slow exhaust to be achieved smoothly by detecting a pressure difference from the atmospheric pressure generated through evacuation of a pipe inside. CONSTITUTION:When, for instance, exacuation is carried out in the direction of an arrow mark, the pressure at A part is lowered due to a closed circular butterfly valve 1 and a bellows 2 shrinks by being prossed with a pressure difference from the outside atmospheric pressure. Then, the circular butterfly valve 1 opens through a link mechanism 3 connected to the bellows 2. Therefore, the pressure at A part is raised a well as B part is evacuated resulting in expan sion of the bellows to close the circular butterfly valve 1 to throttle discharge. B part is gradually evacuated by repeating the above process and the bellows 2 is perfectly shrinks with the circular butterfly valve 1 fully opened under a vacuum state allowing no pressure difference between A part and B part. Thus, slow exhaust can be achieved smoothly because dilicate alteration of conductance in response to the pressure change can be carried out.

Both the upper part and the lower part are deaerated to maintain the reduced pressure vacuum state and thereafter, the counter substrate is brought into tight contact with the coated substrate. The atm. pressure is restored in the upper part and rubber sheet working is executed.  As a result, a pair of the substrates are laminated via the high-polymer soln. in the vacuum state and, therefore, the high- polymer soln. laminate having the negative pressure state in the substrates is obtd. The degree of the reduced pressure vacuum is <=100mmHg, more preferably <=50mmHg. The lower limit is preferably about 1mmHg or 0.1mmHg.
