Title: Simultaneous measuring method for refractive index and its dispersion
Inventor: IMOTO NOBUYUKI
IPC: G01N21/41
Filed: 1978-10-30
Abstract: PURPOSE:To ensure the simultaneous performance of two measurement with one turntable device by measuring the light whose wavelength is slightly longer than the central wavelength of the light and the incident angle with which the short light shows a constant and equal deviation angle through the prism. CONSTITUTION:The area where the light given from wavelength variable light source 1 enters vertically to the face of orism 5 is defined as the zero degree of the revolving angle of sample stage 6. Then light position detector 4 is fixed at a proper position, and the wavelength of source 1 is set to lambda-DELTAlambda/2 to turn stage 6 and then stop the stage before several degrees to incident angle phi10 which gives the minimum deviation angle. The revolving angle of that moment is set to phi1a. After this, angle phi1b which is positioned at the area larger than incident angle phi10 and gives the same deviation angle is read. Then the wavelength of source 1 is set to lambda+DELTAlambda/2 to obtain the similar angles phi1a' and phi1b'. Based on the mean value of these angles, phi10 is obtained, and refractive index n is obtained from phi10 and through calculation. Then change DELTAn caused by angles phi1a and phi1a' plus phi1b and phi1b' are divided by change DELTAlambda of the wavelength to obtain refractive index dispersion dn/dlambda.

Title: Screw compressor
Inventor: URASHIN MASAYUKI
IPC: F04C18/16
Filed: 1988-06-01
Abstract: PURPOSE:To prevent seizure of the end face of a rotor by providing a ring-like thrust bearing whose outer diameter is smaller than the diameter of root circle of the screw rotor and which is formed to be projected from the face of a casing to the casing opposed to the delivery side end face of the rotor. CONSTITUTION:During a normal operation, a thrust bearing 5 takes a thrust from the delivery side of a rotor 1 to the suction side. At the time of starting or stopping, or during operations such as a defrosting operation, etc. where an abrupt change in pressure occurs, a force from the suction side to the delivery side can act on the rotor 1, and the force is received by a thrust bearing 4a. Since the thrust bearing 4a is ring-like, and its outer diameter is smaller than the diameter of root circle of the rotor and formed to be projected from the delivery casing 3, the tooth end face where land parts and groove parts alternate and an oil film is difficult to be formed, does not contact the casing 3, and the rotor 1 is supported by the root circle of the rotor 1 where load faces are formed continuously. As a result, a reliable thrust bearing 4a capable of preventing seizure of the rotor end face can be obtained.

Title: Contactless igniter for internal-combustion engine
Inventor: NAGASAWA MASAO
IPC: F02P3/09
Filed: 1983-07-21
Abstract: PURPOSE:To prevent a capacitor from being overcharged, by short-circuiting the terminals of the capacitor through a short-circuiting semiconductor switching element when the charged voltage of the capacitor is higher than a prescribed level, to keep a high voltage from being induced. CONSTITUTION:In the medium and high speed revolution of an engine, the charged voltage of a capacitor 13 becomes higher than a set level and the potential of the voltage division point between voltage dividing resistors 9, 10 rises, when a second high voltage is induced across a charging coil 1, so that a transistor 6 is turned on and the base of another transistor 8 is short-circuited. As a result, the transistor 8 is not turned on even if a third and other succeeding forward half rectification outputs are generated across the charging coil 1, so that a high voltage is not induced across the coil any more. Consequently, the capacitor 13 is not charged any more. The capacitor 13 is thus prevented from being overcharged.

Title: Dustproof conveyor
Inventor: ONO YOSHINOBU
IPC: B65G54/02
Filed: 1989-05-25
Abstract: PURPOSE:To simplify a device in structure by making turning effort in a roller shaft of a carriage equipped with a wafer carrier provided with a filter so as to be transmitted to a fan in the wafer carrier via an electromagnetic clutch. CONSTITUTION:A secondary conductor 2 installed in the lower part of a carriage 3 is driven by a linear motor 1, traveling this carriage 3. With this, a roller 4a rotates so that a fan 12 rotates as well via a shaft 9a, a gear 10b, a shaft 9b, an electromagnetic clutch 11, and a shaft 9c, and thereby air in a wafer carrier 6 is exhausted out of an exhaust port. When the carriage 3 is stopped, the electromagnetic clutch 11 is cut off before carriage stoppage and the fan 12 is rotated by its inertia. Consequently, even if the carriage 3 comes to a stop, the air in the carrier 6 is exhausted by this inertia. With this constitution, a dustproof effect is thus improved despite structural simplification.

IPC: G06T11/80
Filed: 1995-05-31
Abstract: PURPOSE: To shape any input polygonal figure having even number of apexes to a proper polygonal figure of point symmetry by automatically extracting the center of point symmetry. CONSTITUTION: When a polygon having even number of apexes is inputted, a middle point calculation part 24 makes the m-th apex and the (m+n)th apex out of 2n apexes correspond to each other as a pair of apexes and calculates the coordinates of middle points of n segments obtained by connecting pairs of apexes which are made correspond to each other in this manner. A centroid- middle point distance calculation part 26 calculates the distances between the centroid and middle points. A point symmetry determination part 27 determines the calculated centroid as the center of point symmetry when all distances between the centroid and middle points are within a prescribed allowable range.  When the centroid is determined as the center of point symmetry, a point symmetry processing part 28 corrects coordinates of apexes of the input figure to shape it so that it is a figure of point symmetry which is symmetrical with respect to the centroid.

Title: Check system for transfer data
Inventor: SEKI TAKEO
IPC: G06F11/00
Filed: 1978-10-31
Abstract: PURPOSE: To ensure the check after transfer, by inspecting the check circuit before the transfer of information, in the circuit to check the information from registers to other registers.  
     CONSTITUTION: The check register CRT consists of the T-type latch, and this latch is set to 0 when the stored information is the same as new information. Before transferring information from the registers at other part to the register R 2 , control pulse is fed to the control terminal C 3  to zero each T-type latch. If the T-type latch is normal, the input to the AND circuit via the inverter 11 is all 1 to obtain the AND output. CR is normal if the AND output is present even after the disappearance of the control pulse. Next, when the data are fed to the register R 2  via the gate 8, they are fed also to CR. After that, the content of the register R 2  is fed to CR via the gate 9 and the inverter 16. If there are no error in the data, the two inputs fed to CR are different, and the output of each T-type latch is 1 and 1 output is obtained at the AND circuit 17.
