Title: Die for vertical die casting
Inventor: FUJINO KIYOSHI
IPC: B22D17/12
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent the unnecessary temp. raising of a die by fitting a tubular cover having coolant inlet and outlet on the outer periphery of a tubular groove. SOLUTION: A lower die 1 and an upper die 4 are arranged in the die for a vertical type die casting. In the lower die 1, a pouring hole 6a and a gate 8 are arranged. The lower die 1 is formed with a design die 2 and a backup die 3, and both are fixed with a fastening bolt 26. The periphery of a center shaft in the vertical direction of the design die 2 is formed as the shape having a cylindrical projection 14 which has the small diameter gate 8 at the center part and the smaller outer diameter than the diameter of the pouring hole 6a and directs downward and fits by inserting into the inner surface part of the backup die 3. The tubular groove 13 is formed at the outer periphery of the base part of this cylindrical projection 14. On the outer periphery of the groove 13, a coolant passage (groove) 13 is formed by fitting a cover 15 having the inlet and the outlet of the coolant.  In such a structure, the cooling of the gate 8 and the surrounding in the design die 2 is executed. By this method, the local temp. raising around the gate can be prevented.

Title: Joining method using adhesive and welding in combination
IPC: C09J5/00
Filed: 1992-03-13
Abstract: PURPOSE:To reduce an occurrence of weld defects and to execute tack-working by a general operator. CONSTITUTION:Members 1 to be joined are abutted and tack-bonded together by adhesives or an adhesive tape 4 with little produced gas and then, the members 1 to be welded are subjected to regular welding. Since a partial buildup part as in the case of performing conventional tack-welding is not generated, sound regular welding can be performed and the occurrence of defects of regular welding is remarkably reduced than in the past. In addition, since welding is not required in tack-working, a general operator can execute tack-working.

Title: Shearing interferometer for measuring lateral aberration of lens
Inventor: MATSUDA JOJI
IPC: G01M11/00
Filed: 1991-03-28
Abstract: PURPOSE:To obtain a shearing interferometer with a simple construction by which the lateral aberration curve of a lens can be obtained. CONSTITUTION:A shearing interferometer 1 for measuring lateral aberration of a lens shears a wavefront in a direction of a horizontal axis from a test lens TL with a wedge W of a parallel planar plate and turned about the horizontal axis slightly to tilt. A lateral deviation of an interference fringe as caused by the tilting indicats a phase difference to be obtained by the shearing. On the other hand, in the lateral aberration of the lens, when a parallel light is made to impinge onto the lens, an image is formed at a focal position in the case of an ideal lens but if a lens aberration exists, the image formation occurs at a position deviated from the focal position. A curve depicting the deviation value with the height of the lens taken on the vertical axis and the deviation value on the horizontal axis is a lateral aberration curve. The differentiated value of the wave front multiplied by a focal distance is the deviation value at the focal position. The differentiated value of the wave front is obtained by a shearing interference and the value corresponds to the lateral value of the interference fringe of the tilting. Thus, the interference fringe of the tilting passing through the center of the lens is proportional to an aberration curve to determine a scale of the horizontal axis thereby obtaining the lateral aberration curve.

Title: Excitation controller for synchronous machine
Inventor: SOGABE TOSHIAKI
IPC: H02P27/02
Filed: 1987-04-14
Abstract: PURPOSE:To suppress the sudden boosting of the voltage of a synchronous machine terminal, by adding the signal of counter polarity in proportion to the output of the voltage of the synchronous machine terminal, to the input of a phase controller, when the voltage is established at the time of starting, and by weakening excitation. CONSTITUTION:By a bias signal generator 12, the terminal voltage value of a synchronous machine is detected, and the output of the bias signal of counter polarity in proportion to said value is directed to a phase controller 9. By the bias signal generator 12, it is detected that the terminal voltage of the synchronous machine comes to the rating value of approx. 95-98 % in the proximity of a rating regulating value, and the output of the bias signal generator 12 is cut, then the only output signal of an automatic voltage regulator 7 exsists. Accordingly, the input of maximum rising signal to the phase controller 9 is provided, but the terminal voltage of the synchronous machine immediately comes to the rating regulating value, and so the output of falling signal from the automatic voltage regulator 7 is generated, and by the terminal voltage of the synchronous machine, slight overshooting only is performed, and the voltage is controlled to a rating value.

Title: Inertial supercharging device for multicylinder engine with turbocharger
Inventor: KOBAYASHI AKIO
IPC: F02M35/104
Filed: 1982-05-29
Abstract: PURPOSE:To improve the volumetric efficiency under inertial supercharging, by connecting one primary passage of an intake manifold to the other along a curve and prescribing the ratio of the radius of the inside of the curve to the inside diameter of the former primary passage. CONSTITUTION:The action of a turbocharger 35 is matched in the rapid rotattion range of an engine 31. Inertial supercharging is matched in the slow or medium rotation range of the engine. When a valve 40 is closed, matching is effected in the slow rotation range of the engine 31 because the characteristic frequency of a tube system including a main pipe 34 and extending downstream therefrom is low. When the valve 40 is open, matching is effected in the medium rotation range of the engine because a tube system including a bypass pipe 39 and extending downstream therefrom vibrates and has a higher characteristic frequency. The volumetric efficiency etav is high when the inside diameter D of primary pipes 33A, 33B and the radius R of curvature of the inside of a part coupling the main pipe 34 to the primary pipes are prescribed as R/D>=0.05.

Title: Optical measuring instrument
Inventor: WAKATAKE KOICHI
IPC: G01N21/27
Filed: 1985-04-26
Abstract: PURPOSE:To obtain a true analytic value with high accuracy even if the direction of incidence of measuring light to a reaction measuring pipe deviates from the axis of the pipe by selecting the maximum value of the quantity of transmission by a selecting circuit as the true analytic value from variation in the quantity of transmission of the measuring light due to the movement of the measuring pipe. CONSTITUTION:The extent of reciprocal motion of a support base 11 is so secured that the measuring light l passes through the axis (x) of the reaction measuring pipe F at least once. If the measuring light l off the axis (x) of the reaction measuring pipe F is irradiated, the majority of the measuring light l is reflected irregularly, so the conversion voltage of the quantity of transmission of the measuring light l photodetected by a photodetecting element 5 is extremely low in level correspondingly. Further, when the measuring light lis irradiated while aligned with the axis (x) of the reaction measuring pipe F, the diffused reflection on the surface of the reaction measuring pipe F is small, so said conversion voltage is high in level correspondingly. For the purpose, the high-level voltage value is selected as the true analytic value to obtain accurate analytic data.
