Title: Filter element
Inventor: OKABE KIMIO
IPC: B01D35/147
Filed: 1995-04-25
Abstract: PURPOSE: To obtain a filter element which is constituted in such a way that refuse, etc., which are caught, are prevented from flowing out from the element when it is removed. CONSTITUTION: A filter element is constituted so as to have a lower end plate which covers the lower end part of a cylindrically formed filter medium 20 and in which an inflow hole 14 communicating with the inside space 23 of the filter medium is formed. Fluid introduced from the hole 14 passes through the filter medium 20 from the inside space 23 to the outside to be filtered. A lid member 15 is installed which can move freely between a shielding position for shielding the hole 14 and a opening position for opening the hole 14. The lid member 15 is transferred to the opening position shown by a chain line by the pressure of fluid introduced from the hole 14 and moves to the shielding position indicated by a continuous line when the flow of the fluid from the hole 14 is stopped.

Title: Nut runner
Inventor: KUWABARA MASAYUKI
IPC: B25B21/00
Filed: 1985-06-07
Abstract: PURPOSE:To lower a driver only with its own weight for smooth thread tightening by providing the play in the moving direction of a cylinder joint for transmitting the motion of a piston to a driver section. CONSTITUTION:When air enters 29 in a cylinder 18 of a lift section, a piston 34 desends. Through a cylinder joint 19 descends as the piston descends, said joint does not contact a slider 20 directly connected with a driver since said joint has the play in the moving direction so that the descending motion of the piston 34 is not transmitted to a driver. Thus, the driver section is lowered only by its own weight. When the piston 34 further descends and the cylinder joint 19 contacts the slider 20, the descending motion of the piston 34 is transmitted to the slider 20 through the cylinder joint 19 so that the driver descends to tighten finally a screw.

Title: Mixed flow pump and axial flow pump
Inventor: EGUCHI TAKESHI
IPC: F04D29/66
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To suppress collision of an impeller caused by reverse flow in a low level so as to reduce shaft power near no-discharge operation by providing with an impeller whose angle is variable, a pressure sensor for detecting pressure of flow, and a control device for changing the angle of the impeller on the basis of pressure detected by the pressure sensor. SOLUTION: When a mixed flow pump is started in a no-discharge operation, water is boosted up by an impeller 1, and reverse flow rages are formed on the inlet and the outlet of the impeller 1 for preventing it from flowing. 7 to 9 pieces of impellers 4 are arranged so as to face the inlet and the outlet of the impeller 1 to each other in the circumferential direction of a casing 3, and the impellers 4 are moved at one time by an annular guide ring 6 for enclosing the casing 3 continuously to a lever 5 installed on the rotary shaft 12 of each impeller 4 penetrated on the casing 3. It is thus possible to suppress shaft power in no-discharge operation by setting the installing angle of the impellers 4 so as to suppress collision of flow of the impeller 1 to a minimum level.

Title: Solar radiation sensor
Inventor: TOYODA INEO
IPC: G01J1/42
Filed: 1995-05-24
Abstract: PURPOSE: To provide a solar radiation sensor which can be inexpensively manufactured without adding a process of forming a light shielding film to a manufacturing process of a sensor chip. CONSTITUTION: In a sensor chip 1, a circular first light receiving part 8a is arranged in the center, and an annular ring shaped second light receiving part 8b is arranged in its outside, and a signal processing circuit part 9 is further arranged on its outside. The sensor chip 1 is formed as a package 3 molded by transparent epoxy resin in a state of being mounted on a lead frame 2, and a light shielding mask 5 is formed on its surface. The signal processing circuit part 9 is arranged in an area separate by a prohibiting distance (xo) or more expressed by an expression from the edge of the light shielding mask 5, and any incident light does not reach there. When the solar radiation light is made incident at an angle of 45 deg., it becomes a peak value.  Since a process of covering an upper surface of the signal processing circuit part 9 of the sensor chip 1 with a light shielding member becomes unnecessary, cost can be reduced.

Title: Method and device for generating investigation information
Inventor: MATYAS JR STEPHEN M
IPC: G06F21/60
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To reinforce the functions of an electronic payment system for allowing a buyer to purchase a product by transmitting an electronic payment order to a seller so as to provide product investigation information. SOLUTION: A buyer 10 generates a certification code as an one-way funtion of a secret value generated at random and includes the certification code in a payment order. At the time of providing investigation information to an evaluator 10 thereafter, the buyer 10 includes the secret value in the investigation information. The evaluator 50 provides information for identifying a transaction and the secret value to a buyer's payment demanding system to verify the purchase transaction.  The buyer's payment demanding system extracts a certification code from transaction information received from a seller 20, compares the extracted code with a code regenerated from the secret value by using the one-way function and transmits the compared result to the evaluator 50, which uses the investigation information at the time of certificating that the certification code is related to a practical transaction between the buyer 10 and the seller 20.

IPC: F16C33/64
Filed: 1990-05-17
Abstract: PURPOSE:To improve reproducing performance of working depth and smoothness on a rolling member running face by arranging an electrode in a face-to-face-relation on a bearing basic body having a rough rolling face formed by rough working after forming the bearing basic body, interposing electrolyte between the rough rolling face and the electrode, and applying voltage between them for removing the rough rolling face chemically. CONSTITUTION:A rotating grinding wheel 4 is abutted against the part of a sliding base 1 preliminarily sementation hardened on which a rolling face is formed, and it is ground to form a rough rolling face 11'. After an electrode 5 is arranged with a specified gap to each rough surface 11', electrolyte 6 is flowed in between the face 11' and the electrode 5, and also a pulse D.C voltage 7 is applied to a part between the sliding base 1 and the electrode 5 so that a current is supplied from the side of the sliding base 1 to the side of electrode 5. As a result, the rough rolling face 11' contacting the electrolyte 6 is melted out in the electrolyte 6, and the formation of four lines of load rolling faces 11 is completed on the sliding base 1. Uniform working conditions of voltage application time and the like makes the working depth substantially uniform at every sliding base 1.

Abstract: PURPOSE:To readily obtain the title compound useful as a synthetic intermediate for medicines by reacting an enantiomer mixture of pentanolide derivative with an acylating agent in the presence of an asymmetric hydrogenase. CONSTITUTION:First, an enantiomer mixture of pentanolide derivative shown by formula I (R is alkyl) is allowed to react with an acylating agent shown by the formula R<1>COOR<2> (R<1> is alkyl; R<2> is H or alkyl) in the presence of an asymmetric hydrogenase (e.g. lipase derived from Candida cylindracea) preferably at 25-50 deg.C to stereoselectively convert hydroxy group at the 3-position of one optically active substance into an acyloxy group. Then, a formed optically active 3-hydroxy-4-pentanolide derivative is separated and collected. The enantiomer mixture of the raw material, for example, is obtained by subjecting a propanal compound shown by formula II to the ring closure reaction in the presence of zinc and a di-lower alkylaluminum chloride.
