Title: Scroll type vacuum pump
Inventor: NAKANO YODO
IPC: F04C25/02
Filed: 1985-06-10
Abstract: PURPOSE:To prevent the increase of the driving torque by forming a plurality of relief holes which permit the communication between the operating space and the discharge side when the pressure in the operating space becomes over a prescribed discharge pressure, onto the fixed scroll member of a scroll type vacuum pump. CONSTITUTION:A plurality of communication ports 4 which communicate to an operating chamber 19 and a discharge side space 100 are formed onto the fixed scroll member 2 of a scroll type vacuum pump, and a check valve 16 which is opened when the pressure in the operating chamber 19 exceeds the discharge pressure is arranged at the opened part to the discharge side space 100 of the communication port 4. Therefore, even if the excessive compression is generated in the operating chamber 19 during the operation of the vacuum pump, the excessively compressed fluid is released into the discharge side space 100 by the discharge valve 16 safely, and the action of an excessive load onto a driving source because of the increase of the driving torque is prevented.

Title: Hydrosol or gel of polyanion polymer, its preparation, and preparation of enteric drug using the same
Inventor: KURIHARA KOUZOU
IPC: A61K47/30
Filed: 1978-10-13
Abstract: PURPOSE: To prepare the title novel sol or gel, useful as a coating material of an enteric drug, by dissolving a water-insoluble polyanionic polymer in water in the presence of a basic substance, and adding an acidic substance to the solution.  
     CONSTITUTION: A water-insoluble polyanionic polymer (e.g. hydroxypropylmethylcellulose phthalate) is dissolved in water containing a basic substance (e.g. sodium hydroxide), or a water-soluble basic salt of the above polymer is dissolved in water,  to obtain a solution. The basic substance is neutralized by adding an acidic substance (e.g. hydrochloric acid) to the solution under stirring, to obtain the title hydrosol or gel. The hydrosol or gel thus obtained is used as a coating material of various drug preparations under ordinary conditions. Since the preparation thus prepared has an weakly acidic coating layer of the polymer, it does not dissolve in the stomach having strong acidity, and dissolves in the intestines.

Title: Winding method for automatic winder
Inventor: SHIOMURA SHIGEO
IPC: D02J1/22
Filed: 1986-05-30
Abstract: PURPOSE:To reduce occurrence of sloughing, by winding yarn which is tied after it has been cut by sloughing while the yarn is wound at a speed at least lower than an initial normal winding speed. CONSTITUTION:When sloughing is caused in winding yarn, a slub catcher 6 senses a defective portion of the yarn for causing a cutter 13 to cut the yarn at once. Further, a yarn clearer 10 applies a sloughing sensing signal 21 to a control circuit 19 to permit an inverter 18 to be controlled. The yarn is wound again in a time necessary for tying it after it has been cut by sloughing. The winding speed at the time is set to a value smaller than an initial winding speed. The winding speed after the yarn is tied is not changed even if sloughing is caused again in winding. Therefore, sloughing is not caused repeatedly and yarn is wound effectively.

Title: Logic integrated circuit
Inventor: NAKAMURA YOSHIYUKI
IPC: H03K19/00
Filed: 1992-05-20
Abstract: PURPOSE:To test all of the clock signals in a scan path circuit in which a polyphase clock can be handled. CONSTITUTION:When a scan mode signal SMC is '0' and a clock signal CK1 is '1', an output signal T11 of a latch circuit 1a becomes '1' and an output signal T12 of an AND gate 2 becomes a value of the first test clock signal SCK1 to be used for a clock of a scan circuit 6, so that the value of a data input signal D is fetched into the scan circuit 6. On the other hand, when the clock signal CK1 is '0', the value of the latch output signal T11 becomes '0' and the output signal T12 of the AND gate also becomes '0', so that the scan circuit 6 does not fetch the data input signal D into it and keeps the value that is scan-inputted. In this way, the difference in the clock signals CK1 can be reflected on the output of the scan circuit 6.

Abstract: PURPOSE:To remove and recover efficiently with small amount of equipment expense by using a non-water permeable film, bringing water solution in which subject compound is dissolved into contact with one side of said film, setting a specified condition on the other side and permeating subject compound which is contained in industrial waste water, service water and the like and gives an unpreferable effect on human bodies and the like. CONSTITUTION:Water solution in which halogenated hydrocarbon is dissolved is brought into contact with one side of a non-water permeable film and the vapor pressure of said halogenated hydrocarbon is made close to zero for the purpose of permeating the halogenated hydrocarbon and removing and recovering said permeable compound. The process of making the vapor pressure of said water solution component is, for instance, removing the permeable component mechanically by a vacuum pump or the like, or flowing inactive gas and removing the permeable component and the like. For instance, it is preferable to use Teflon, polyethylene or the like in the hollow yarn state or in the flat film state. Also, as for the recovering process for the subject compound, the inactive carbon adsorption process and the like are utilized.

Title: Sash window
Inventor: HOSOOKA SHUICHI
IPC: E06B3/06
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a sash window offering various selective heat insulating performance and reduced cost. SOLUTION: A sash window is formed on a window frame 2 framed at its four peripheries with an upper frame 41, a lower frame 12 and right and left vertical frames by the combination of sashes selected out of sashes 5-9 which are different in heat insulating performance and have holding grooves of the same opening sizes L6 for holding a double glazing. The sashes 5-9 different in heat insulating performance are properly selected to be assembled into the window sash 2 so that the sash windows different in heat insulating performance can be easily manufactured at lower cost. The sashes 5-9 having holding grooves of the same opening size L6 provide the use of the double glazing in common. As a result, the types of parts such as glasses and gaskets are reduced and assembling and ordering errors are reduced to lead to reduction in manufacturing and inventory managing costs.

Title: Bookshelf type record player
Inventor: MORITA JUJI
IPC: G11B17/04
Filed: 1980-09-13
Abstract: PURPOSE: To ensure a continuous and assured operation of a record player, by detaching a locking pin from a rack at the position of performance and securing the engagement between the locking pin and the sliding base when a record is on a turntable.  
     CONSTITUTION: When a record is put on a turntable, a record detection pin 11 lowers down and at the same time a resetting plate 10 is detached from a cam 4a to turn a record detecting lever 9 counterclockwise. Then the pin 11 turns the lever 9 from the position shown by a dotted line to the position shown by a solid line. As a result, even if a sliding base moves back, a pin 9b of the lever 9 does not engage a hook 8a of a lock lever resetting plate 8. When the slide base reaches the position of performance, a pin 7a of a locking lever 7 which is already reset and energized clockwise is put into a cut 1b of a suide wall 1a to hook the sliding base. Thus the hooking of the rack 5 is cancelled.

Abstract: PURPOSE:To provide a picture recognizing method capable of the edge detection equivalent to the human's visual recognition in an arbitrary space scale. CONSTITUTION:Original pictures are represented in L*Cab*Hab deg. color spaces. The convolution arithmetic operation with the Laplacian of Gaussian function is performed for three coordinate value L* (clearance), Cab* (chroma), and Hab* (hue), thereby obtaining the zero intersection point where the three functions become zero and extracting the zero intersection point as the edge section for respective three coordinate values. Then, the information on the edge section of original pictures can be obtained by synthesizing information on these edge sections.
