IPC: H01L21/66
Filed: 1988-02-22
Abstract: PURPOSE:To three-dimensionally, highly accurately, and quickly detect the notch and bend of the lead of a circuit pattern formed flexibly by moving an optical displacement measuring instrument which measures the displacement of an object to be measured by projecting a light beam on the surface of the object in a plane. CONSTITUTION:An optical displacement measuring instrument 1 which measures the displacement of an object to be measured by projecting a light beam 9 on one point of the surface of the object is fitted to a two-dimensional moving device 2 and moved at high speed in accordance with a lead 8 formed on a flexible table 6. A part of the irregularly reflected light on the lead 8 is received by a light receiving lens and focused on a light receiving position detecting element in corresponding to the displacement of the lead 8 in the direction of the optical axis. Therefore, when the output signal of the element is detected with high accuracy, presence/absence and the displacement in the optical-axis direction of the lead 8 can be detected highly accurately.

Title: Control device for steam turbine
Inventor: MATSUMOTO SENJI
IPC: F01D15/10
Filed: 1980-03-27
Abstract: PURPOSE: To prevent the fluctuation of frequency of generated power at the time of releasing pressure-regulating operation by a method wherein a signal of deviation of the generated power from the position of a synchronizing device is transmitted to a motor for the synchronizing device only at the time of releasing the pressure-regulating operation.  
     CONSTITUTION: Signals of an output detector 15 and a position detector 16 of the synchronizing device 10 are compared by an operator 20 and a compensation signal is delivered from a regulation meter 17 to the motor 11 for the synchronizing device. When a breaker 2 is opened and the steam turbine 4 is switched over from the pressure-regulating operation to speed-regulating operation, a switching element 23 is closed. At this time, a control signal of the regulation meter 17 maintains the output of a power generator 5 and the motor 11 for the synchronizing device prevents the increase in the rotational number of the turbine, while a steam-adjusting valve 9 does not open rapidly. In this way, the fluctuation of frequency can be reduced at the time of releasing the pressure-regulating operation of the steam turbine.

Title: Detecting method for shaft center of motor
Inventor: SHIOZAWA ETSUO
IPC: G11B19/20
Filed: 1986-02-26
Abstract: PURPOSE:To detect a shaft center of a rotation shaft of a motor from its outer diameter with high accuracy by halving the interference fringes on a globe observed by an interference microscope or the outer diameter of the globe observed by an optical microscope in order to detect the shaft center of the rotation shaft. CONSTITUTION:To detect the shaft center of the rotation shaft 5 of a motor to which a steel ball 36 is attached a chassis 28 is fixed on a jig (not shown in the figure), then the steel ball 36 attached on the shaft 5 is observed by the interference microscope 70 with the shaft being stationary. In the field of view of the microscope 70, dense annular interference fringes generated on the steel ball 36 are seen. Since the sphericity of the ball 36 is high, the center of said fringes coincides with that of the ball 36 i.e. the center of the shaft 5, and also the fringes themselves are accurate and of high visibility. Therefore, by obtaining the position that halves the distance between the positions that are 180 deg. apart from each other on, for instance, the secondary fringe out of the interference fringes (diameter of the annulus ring), the shaft center of the rotor 5 can be determined with a high accuracy.

Filed: 1987-02-24
Abstract: This invention relates to formaldehyde-free, aqueous glue dispersions which contain polyisocyanates. These systems are particularly suitable for gluing veneers and surface materials on wood and wood products. The systems are prepared from polyisocyanates in combination with extenders based on flours and cold water-soluble of hydrolyzed natural starch. In this process, polyisocyanates or aqueous dispersions thereof are added while stirring to aqueous solutions or mixtures of starch and flour. The extender-containing adhesive systems are aqueous glue dispersions having increased service life which in their preferred embodiment contain about 15 to 30% by weight of polyisocyanates, preferably polyphenyl-polymethylene polyisocyanate (PMDI), 10 to 15% by weight of starch which is soluble in cold water and 14 to 25% by weight of (cereal) flour and optionally, other additives and the appropriate quantity of water adding up to 100% by weight. The glue dispersions are easily applied with glue spreading machines and if applied in suitable quantities do not bleed through veneers. The implements used for applying the glues can easily be cleaned by rinsing them with water. The invention is also directed to the use of the glue dispersions for gluing, particularly for gluing veneers or other surface coating materials to wood or wood products.

Title: Adjusting device for instrumental error of flowmeter
Inventor: IWATA SEIICHI
IPC: G01F1/12
Filed: 1980-03-28
Abstract: PURPOSE:To improve durability of the device, by uniforming the force which rotates the impeller to rotate the impeller smoothly by providing the adjusting plate, which adjusts the area of the flow hole of the rectifier, concentrically for the flow of the fluid to be measured. CONSTITUTION:Instrumental error adjusting plate 30 is provided concentrically for the flow of the fluid to be measured, and this adjusting plate 30 is turned in the arrow direction to increase and reduce the area of flow hole A of rectifier 2, thereby adjusting the instrumental error. In this instrumental error adjustment, the fact that the relation of omega/Q is changed when area F of flow hole A is changed is utilized on a basis of the relational expression between the flow rate of the fluid to be measured and rotation of impeller 4 (Q, omega, C, r<->, F and theta are the flow rate to be measured, the angular velocity of the impeller, a constant, the average rotation radius of the impeller, the area of the flow hole, and the impeller angle respectively). Thus, the deflected flow is not generated in the fluid to be measured, and the force which rotates impeller 4 becomes uniform to rotate impeller 4 smoothly, and therefore, durability is improved.

Title: Business management method and device, and storage medium where its program is recorded
Inventor: TAJI RYUTARO
IPC: G06Q50/00
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To perform business management even for a non-routine job or even in a work system wherein a worker's role is not well defined by allowing all workers to share business information through multi-address communication and determining necessary operation and their role by their own judgement according to the business information. SOLUTION: A server 11 always has a registration report on a new business item or business information change report received by a communication part 3 from a client 12 and starts a processing when receiving any information. Once the processing is started, a state management part 1 determines whether it concerns the registration of a new business or a change in an existing business, and generates an entry of the new item on a data base and sets it in an unprocessed state in case of the registration of the new item. Here, a necessary work and assignment are determined by a worker's judgement, and when the state of a business item is changed on the indication, the state of the item on the data base is changed. Then the new state of the item is informed through a multi-address communication part 2 to all workers.

Filed: 1990-02-21
Abstract: PURPOSE:To obtain a uniform magnetic field between electrodes by arranging a superconductive material on a peripheral part of a magnetic gap. CONSTITUTION:A deflection electromagnet 42 has a sectionally C-shaped core 44 while having magnetic poles 48, 50 oppositely arranged through a magnetic vacant space 46 and arranging a vacuum container 22 along a magnetic vacant space 46. That is, since the magnetic vacant space is allover surrounded by superconductive plate materials 60, 62, 64, generated magnetic flux 56 between magnetic poles 48, 50 is bounced at the superconductive plate materials 60, 62, 64 due to the Meissner effect so as to cause no leakage magnetic flux by making the superconductive plate materials 60, 62, 64 a superconductive state. Thereby, the inside of the magnetic vacant space 46 gets uniform magnetic field strength both in the circumferencial and diametrical directions.
