Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To carry out work of winding and blocking a mouth of a bag in a stable manner and increase the speed and efficiency of the work as a whole. SOLUTION: After a mouth Ba of a bag B with which flaps Aa of a case A are covered is wound upward by a windup mechanism, the mouth Ba of the bag B wound up is flattened in forward and backward directions by a flattening mechanism. By driving a deaerating mechanism, both side faces of the bag are pressed with press plates to perform deaeration and, by driving fore and rear winding mechanisms 7, a pair of winding bars 61 disposed forward and backward are moved horizontally in directions opposed to the fore and rear edges of the bag B. After inserting the flat side edges of the bag B between the paired winding bars 61, 61 by a suitable size, respectively, the paired winding bars 61 disposed forward and backward are rotated in the winding direction while lowering them.  Since the mouth Ba of the bag B is wound suitable times to be blocked as it is being kept in a flat state, work of winding and blocking the mouth Ba of the bag B can be carried out efficiently.

Filed: 1980-06-10
Abstract: PURPOSE:To reliably perform an electrophoretic measurement with a constitution needing no movable part, by calculating the electrophoretic speed from the ratio of the Fourier-transformed outputs of the images, corresponding to the suspended particle distributions, detected by a diode array before the starting of electrophoresis and after a given time has passed since the starting. CONSTITUTION:The image of the sample particles injected into an electrophoretic tube 1 and irradiated with light is detected by a diode array 5. The Fourier-transformed value G(n) of the suspended particle density in the x direction of the rectangular coordinates at time 0 is stored in a 2 channel memory 8 through a CPU 12, an A/D converter 13, a Fourier transformer 7 and the like. Then, the Fourier-transformed value K(n) similarly obtained after a given time, e.g. two seconds, has passed since a voltage was applied between electrodes 2 and 3 to electrophoretically move the suspended particles is stored in the other channel of the 2 channel memory 8. When the ratio of both the contents of the memory 8 is calculated in a divider 9, the electrophoretic speed Fourier-transformed value phi(n) of the suspended particle density ratio according to the equation I is determined, and the electrophoretic speed is reliably detected through a reverse Fourier transformer 10, with a constitution having no movable part.

Title: Metal vapor discharge lamp
Inventor: WATABE KEIJI
IPC: H01J61/52
Filed: 1982-05-11
Abstract: PURPOSE:To prevent the hanging down of a tungusten coil and/or the damage of an outer tube caused by the overheating of a resistor while a lamp is being turned on by providing a heat screening body around the resistor. CONSTITUTION:Normally, at the first opening of a bimetal switch 3, a lamp comes on, but if the high voltage pulses generated in this case are in sufficient for the start of the lamp, the lamp cannot come on. When the bimetal switch 3 is closed again, current flows again in a carbon coat resistor 17, a heater 16, and the bimetal switch 3 and the bimetal switch 3 is actuated and high voltage pulses are regenerated. When the actuation of the bimetal switch 3 is repeated several times at the start of the lamp like this, the temperature of the carbon coat resistor 17 rises gradually from normal temperatures and an outer tube 10 is heated by this heat and may be cracked. Since a heat screening body 18 is provided around the carbon coat resistor 17 in this invention, the heating of the outer tube 10 is reduced by this heat screening body 18.

Title: Cooling cylinder for single crystal pulling-up device
Inventor: NISHIZAKI KATSUMI
IPC: C30B15/00
Filed: 1991-04-11
Abstract: PURPOSE:To increase the pulling-up velocity of single crystal by constituting the cooling cylinder of a double structure which is formed of both a specularly worked outer cylinder small in emissivity and a cooling inner cylinder having an outer face plated with gold and being large in emissivity while pinching the void. CONSTITUTION:A cooling cylinder 1 for a single crystal pulling-up device is constituted by forming a double structure of both an outer cylinder 2 and a cooling inner cylinder 3 described below while pinching the void 5. The outer cylinder 2 is obtained by specularly working the material small in emissivity such as SUS. The cooling inner cylinder 3 is obtained by spirally winding a tube made of the material large in emissivity such as Cu and plating the outer surface of the tube with gold. Single crystal 9 is pulled up from melt 8 in a crucible 7 and also cooling water 10 is passed through the cooling inner cylinder 3 to cool single crystal 9. Radiation heat emitted from an external heater 6 is reflected by the outer cylinder 2 of the cooling cylinder 1. On the other hand, the radiation heat emitted from single crystal 9 being pulled up is endothermically absorbed by the cooling inner cylinder 3. As a result, gaseous SiO2 ascending from melt 8 is not stuck on the cooling cylinder 1 but is discharged. The pulling-up velocity of single crystal 9 is increased.

Title: Humidity sensor made of crystal resonator
Inventor: GOTO MASAO
IPC: G01N5/02
Filed: 1987-03-31
Abstract: PURPOSE:To improve a moisture sensitive characteristic by bonding a trialkoxysilane compd. expressed by the specific formula on a vapor-deposited film of a crystal resonator formed with a vapor-deposited SiO film on the surface. CONSTITUTION:The trialkoxysilane expressed by the general formula H2N(CH2) nNH(CH2)mSi(OR)3 (where n and m are 2 or 3, R is a lower alkyl group), for example, 3-(2-aminoethyl aminopropyl)trimethoxysilane, is bonded to the vapor- deposited film of the crystal resonator formed with the vapor-deposited SiO film on the surface. More preferably, methacrylamide alkyltrialkyl ammonium halide is further bonded thereto. The bonding of these compds. is executed by immersing the film for the prescribed time at the prescribed temp. in an aq. soln. of the compd. of the crystal resonator. The sensitivity to humidity is thereby enhanced to a higher level than in the case of using a polyamide polymer.

Title: Pressing mechanism of printing head
Inventor: KOIKE SHOJI
IPC: B41J25/316
Filed: 1986-04-04
Abstract: PURPOSE:To reduce noise during printing by pressing a printing head to a printing surface by means of a shuttle motion obtained through rotary movement of a cam consisting of a cam connected to a rotational shaft or a cam consisting of a disc having an eccentric rotational shaft. CONSTITUTION:When a printing head 4 shuttles back and forth by the rotation of a cam 2, a printing pattern forming part 5 repeatedly presses a printing sheet 9 onto a platen 10. As a result, a printing pattern is printed on the surface of the printing sheet 9. If a motor is stopped or the distance between the printing head 4 and the sliding surface of the cam 2 is maintained, a contact between a printing forming surface and the printing ribbon 8 or the surface of the printing sheet 9 is lost, resulting in the stopping of printing. Noise is reduced by employing the pressing mechanism of the printing head and subsequently the operation of the printing head is accelerated at high speed and ordinary type sheet can be printed by the head.

Title: Transfer device of recording medium
Inventor: NISHIO TSUYOSHI
IPC: G11B15/68
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To miniaturize a cassette changer device utilizing an elevator system by reducing the space between the elevator and a loading/unloading part of a recording/reproducing device as much as possible. SOLUTION: When the cassette recording medium 12 is inserted, a tape streamer part 28 is transferred to the half injecting state to house the inserted cassette recording medium 12 inside this part. When the eject is instructed, the tape streamer part 28 is transferred to the half ejecting state without ejecting the cassette recording medium 12 housed therein in spite of the instruction of a host computer, then the cassette recording medium 12 is discharged awaiting the instruction of a cassette exchanging part 20. Thus, the collision of the cassette recording medium 12 with the elevator 200 is prevented in the manner of eliminating by the tape streamer part 28 that the cassette recording medium 12 becomes the half inserting state, during the time the elevator 200 is possibly moved.
