IPC: B65D5/74
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To weld both of members to a packaging material with sufficient strength and to reduce the time required for welding by a method wherein at least one out of two kinds of members respectively made of two kinds of materials that are incompatible is heated with a burner equipped with a plurality of nozzles and one member is pressed against the other member. SOLUTION: For a packaging container housing liquid food such as milk, a film at the surface of a packaging material forming the container main body is melted with hot air blown upon a cap attachment part at the top of the main body, and a cap body is welded to the packaging material. For a burner unit 72 used for welding of the film, a pair of buners 71 are fixed, being opposite to a picking device that holds the container. With grouped nozzles comprising of a plurality of nozzles 74 arranged at each of the burners 71, a plurality of fine flames are produced. The peripheral part at the reverse side of the cap body is partly heated with such flames, and the material especially polyester resin forming the cap body is made quickly meltable and the cap body is welded quickly to the material, for instance polyethylene resin, that forms the packaging material.

IPC: G11B5/62
Filed: 1990-05-28
Abstract: PURPOSE: To reduce the crosstalk noise and the deterioration of signal output by arranging to shift the position of a pair of upper/lower magnetic disks holding a glass substrate magnetic disk therebetween. CONSTITUTION: The substrate of the magnetic disk 1 consists of glass, and the magnetic layers are vapor-deposited on the upper surface and lower surface sides of this substrate. The 1st magnetic head 2a is arranged on the upper surface side of this magnetic disk 1 and supported by a 1st slider 3a. Also, the 2nd magnetic head 2b is arranged on the lower surface side of the magnetic disk 1 and supported by a 2nd slider 3b. Then, the 1st magnetic head 2a and the 2nd magnetic head 2b are arranged so that the recording tracks are shifted by (d). By this arrangement, the attenuation amount of signal output and the crosstalk noise are remarkably reduced without forming a shield layer on the substrate of the magnetic disk 1.

Title: Temperature display unit of cooking device
Inventor: MORI KEIICHI
IPC: G01K7/00
Filed: 1979-10-19
Abstract: PURPOSE: To make it possible to easily make sure of a temperature, by displaying the present temperature state of the food to be cooked, as compared with the set temperature.  
     CONSTITUTION: The potential A is compared with the reference potential B, C by forming the window comparator by comparators 18, 19. When the temperature is lower than a set temperature, the resistance value of the sensor 9 is large, and therefore the relation among said potential becomes A>B>C, and only the lamp L 20 is turned on. When the temperature has become higher than the set temperature, the resistance value of the sensor 9 becomes very small, and said relation becomes B> C>A, and therefore only the lamp H 21 is turned on. Subsequently, when the relation of the potential has become B>A>C, both the outputs of the comparators 18, 19 become high, and therefore the pilot lamps 20, 21 are turned off, and the pilot lamp 25 is turned on, by which it is displayed that temperature is within the range of the set temperature.

Title: Batchwise kneading machine
Inventor: OTAKE SHOSUKE
IPC: B01F7/04
Filed: 1992-04-28
Abstract: PURPOSE:To improve kneading efficiency together with self-cleaning and to lessen the wear of paddles. CONSTITUTION:The paddles rotate while the peak parts 6c of the major diameter parts 6a of the one paddle come into contact with the peak parts 7d of the minor diameter parts 7d of the other paddle 7 or the peak parts 6d of the minor diameter part 6b of the one paddle come into contact with the peak parts 7c of the major diameter parts 7a of the other paddle 7, when the one paddle 6 and the other paddle 7 are rotated in directions different from each other and at different speeds. Two material spaces (max. space areas) are formed together with the rotation. The materials are then begun to join and are successively compressed until the materials are largely compressed in the one narrow material space. The chances of surely mingling with each other and coming into frontal collision are thereby increased. The materials are thus uniformly mingled with each other. In addition, the number (n-set) of the major diameter parts and minor diameter parts of the one paddle and the number (m-set) of the major diameter parts and minor diameter parts of the other paddle are not equal and, therefore, the materials are further effectively kneaded.

Title: Vertical pump
Inventor: TAKAHASHI MASUHITO
IPC: F04D13/00
Filed: 1988-06-02
Abstract: PURPOSE:To remarkably reduce vibration and noise so as to relax the harmful effect to the title pump by interposing a valve body in an intake passage for intercommunicating an impeller to the inside of a pit at a minimum level and connecting the valve body or a valve body actuating source with a valve body opening/closing mechanism. CONSTITUTION:As a water level becomes a minimum water level LWL, a valve body 11 is opened so as to speedily introduce a large quantity of air inside an intake bell-mouth 3. That is, since an impeller 1 is intercommunicated to the air, thus operating the pump in the air so as to avoid the occurrence of air intake swirl and respiration phenomena so that it is possible to remarkably reduce the vibration and noise. Since the operation changing timing can be relayed with the valve body actuating source only during the water level is varied in a region A ranging from the minimum water level LWL to a pumping starting water level HWL, it is unnecessary to frequently perform the change between the air operation and pumping operation in a short cycle. Thus, it is possible to reduce the frequency of the impact generated each change and remarkably relax the harmful effect to the pump.

Title: Transistor-driven intermittent wiper
Inventor: ANDOU FUJIHIKO
IPC: H02P7/00
Filed: 1979-10-22
Abstract: PURPOSE: To eliminate the necessity for a relay and obtain a wiper device durable and good in quality, by such constitution that to a transistor operated by an output signal from a blocking oscillator circuit a wiper motor is connected in series.  
     CONSTITUTION: When a transistor Tr2 is conducted an electric current by an output signal from a blocking oscillator circuit 1, the electric current flows in a wiper motor 5 to start rotating the wiper motor 5. If the rotating motion of the wiper motor 5 causes a movable contact 6a of an automatic stop switch 6 to be contacted to a fixed contact 6b, the wiper motor 5 holds its rotating motion. Because the output signal from the blocking oscillator circuit 1 is intermittently output, the Tr2 is turned off before a completion of one revolution of the wiper motor 5. Accordingly the movable contact 6a of the automatic stop switch 6 is selectively contacted to the fixed contact 6c to short circuit the wiper motor 5.

IPC: G06F13/36
Filed: 1991-06-07
Abstract: PURPOSE:To eliminate the interference of data transfer between an initiator and a target by excluding driving to be suddenly executed to an SCSI bus when a power source is turned on/off. CONSTITUTION:At a time point when the power source is turned on, a negative control voltage is outputted from a power source on/off detector 2 for fixed time and inputted to the gate of an NMOS transistor 4, and the transistor is turned off. Therefore, the drive of an illegal output to the SCSI bus to be executed through an NMOS transistor 3 and an output terminal 51 according to an SCSI bus output signal in an indefinite state from a controller inside circuit 1 is masked. After the lapse of the fixed time, the transistor 4 is turned on by the positive control voltage of the detector 2, the mask operation is canceled, and a normal operation state is started. Even at a time point when the power source is turned off, the transistor 4 is turned off for the fixed time so as to mask the drive of the illegal output to be executed through the transistor 3 and the terminal 51 to the SCSI bus.
