Title: Film picture plane position detector
Inventor: KANEKO ROKUSABURO
IPC: G03B27/46
Filed: 1989-06-29
Abstract: PURPOSE:To eliminate influence caused by the difference in film base densities by reading the DX code of a film, retrieving the base density of each film type based on this read DX code, and deciding a picture plane position based on this base density. CONSTITUTION:When a negative film 14 is inserted from the inlet of a film carrier, a film detecting sensor 41 detects the insertion of the film. A controller 50 fetches a signal from a DX code sensor 43 with this detected signal, and retrieves the base density of the film 14. The controller 50 carries the film 14 as well. By this carriage, each picture plane is scanned by a light receiving sensor 77, and a Dmax is extracted by a Dmax extracting part 88. This Dmax is read out from a RAM 53 by a comparator 89, and is binarized based on the obtained film density signal via a D/A converter 90. The controller 50 detects the edge of each picture plane with the binarization signal. Thus, each picture plane is positioned to a film watching window.

Title: Power transmission
Inventor: SAEKI MANABU
IPC: F16H55/36
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To reduce the weight and cost of a pulley device provided with a limiter mechanism by changing material used for a V-pulley and a hub, to resin material. SOLUTION: When normally operated, a shoe 5 provided to protrude from the outer periphery of a cylindrical hub 4 is pressed by the energizing force of a pressing part of a spring into a recessed groove 6 formed at the side face of a V-pulley 3 belt-driven by an engine. The V-pulley 3 and hub 4 are thereby fitted ruggedly to transmit rotational power from the engine to a driving shaft of a compressor. When a limiter is actuated, the rotation of the hub 4 is stopped, and after the shoe 5 comes out from between the pressing part of the spring and the recessed groove 6, the projecting part of the spring works to cover the recessed groove 6. The rugged fitting of the V-pulley 3 and hub 4 is thereby released to cut off a power transmission path extending from the engine to the driving shaft of the compressor.

Title: Double-raw type stepless speed changer for car
Inventor: HAYASHI TAKASHI
IPC: B60W10/10
Filed: 1986-07-17
Abstract: PURPOSE:To secure sufficient durability for a long period of time even for a car with a large capacity engine by using two stepless speed change mechanisms arranged parallelly, and thereby transmitting the engine output separatively. CONSTITUTION:Stepless speed changers 4F, 4R are arranged parallelly on input shafts 8F, 8R and on independent output shafts 10F, 10R. This allows torque transmission from the input shaft 8F to output shaft 10F and from input shaft 8F to output shaft 10R at speed ratios variable steplessly. Here a viscous coupling 3 divides the input shaft 8 into stepless speed changers 4F, 4R for the input shafts 8F, 8R individually. Accordingly when specified values are given to the target revolving speed of engine E/G and the target torque distribution proportion to the front and rear wheels, the stepless speed changer 4F controls so that the engine E/g will get the target revolving speed, and at the same time, the target input shaft revolving speed of the other stepless speed changer 4F is controlled so that the target torque distribution proportion is obtained, wherein the torque transmitted through said viscous coupling 3 is taken into consideration.

Title: Gas chromatographic method and gas chromatograph mass-spectrometric method
Inventor: BANDO TOMOMI
IPC: G01N30/06
Filed: 1992-06-26
Abstract: PURPOSE:To provide sensibility for DEP with a high sensitivity by turning the DEP thermally stable into derivative using anhydrous trifluoro acetic acid as a reagent for turning into derivatives. CONSTITUTION:DEP as one sort of agricultural chemicals for use in a golf place is very unstable thermally. Anhydrous trifluoro acetic acid as a reagent for turning into derivatives is added to a solution of DEP, and the resultant is left as it is at room temp. for five min. Adding 1-10vol.% trifluoro acetic acid to the DEP solution turns the DEP into derivatives and stabilizes according to the equation C4H8Cl3O4P+CF3COOH C6H7-Cl3F3O5P+H2O. Because of quick and high sensitivity analysis, the temp. rise speed can be set high, and even though the column oven attains the pyrolytic temp. before the DEP flows out, the DEP remains within the column without undergoing decomposition. Accordingly the setting of the temp. rise speed is free from restriction, and also the analyzing time can be shortened.

Abstract: PURPOSE:To make injection of ink sure and improve ink injecting characteristics by a method wherein ink feeding grooves connecting piezoelectric elements and a common ink layer are arranged in multiple layers in a drop-on-demand type multi nozzle print head. CONSTITUTION:The ink feeding grooves 2 connecting the piezoelectric elements 3 and the common ink layer 1 are arranged by laminating either single plates formed with the grooves 2 on both surfaces thereof respectively or more than two sheets of plates formed with the same. As a result, since it becomes not necessary to arrange a multitude of ink feeding grooves 2 on one sheet of plate, the width of the ink feeding groove 2 can be made wider and the injection of the ink becomes easier to be effected, at the same time, since the ink feeding groove can be made longer, an influence of the pressure in the piezoelectric element 3 to the stream of the ink in the other nozzle through the ink feeding groove 2 and the common ink chamber 1 is reduced when the piezoelectric element 3 is contracted.
