Filed: 1981-04-24
Abstract: PURPOSE: To cut a glass plate into many glass pieces in a short time simultaneously and in high precision, by cooling the face of a glass plate with scribing lines set and heating the other side while pressing the glass plate from both the faces.  
     CONSTITUTION: The scribed face of the work 21 which is previously provided with the scribing line is set in such a way that it is brought into contact with the cooling plate 20 cooled by water, etc., and compressed while being pressed by the heating plate 22 heated at about 100W350°C. The face of the work 21 in contact with the heating plate 22 is heated quickly, expanded in the right and left direction with the scribing line as the center as shown by the arrow 23, and the face in contact with the cooling plate 20 is not expanded. consequently, high tension occurs near the scribing line in the direction equal to the arrow direction, so that the breaking face 24 is formed in a face perpendicular to the face of the work 21. In the work 30 of sandwich glass, a scribing line is set on the face of the glass plates 31 and 32 on the side of the cooling plate 20. The glass is cut more easily by putting the spacer 34 consisting of a heat conducting material such as copper, etc. between the heating plate and the glass in pressing and heating.

Filed: 1984-03-28
Abstract: PURPOSE:To stabilize the tape driving path and to give no damage to the tape by shifting a tape guide by the elastic power in the width direction of the tape like a tape reel. CONSTITUTION:A drive shaft 21 of a tape reel 19 of a magnetic recording/reproducing device is fitted to a recessed part of the reel 19 when a tape cassette is loaded to said recording/reproducing device and also pressed toward an upper half 14.

Title: Reactor water supply flow rate control device
Inventor: TEJIMA TOSHIAKI
IPC: G21D3/08
Filed: 1993-03-22
Abstract: PURPOSE:To suppress supply water flow rate variation during the normal operation maintaining the advantage of 2 loop control method by adding a 'gain and delay compensation' circuit to the signal of motor drive supply pump inlet flow rate as a feedback signal. CONSTITUTION:To reduce the water level fractuation in a rector, a two-loop control method with good control convergence is constituted of a main controller 4, M-RFP (motor driven supply pump) 5 and T-RFP (turbine driven supply pump) flow rate controller and water level variation is recovered rapidly. The M-RFP 5 is driven by a constant revolution motor and the pump flow rate is controlled with a supply flow rate control valve 7. Therefore, the small variation of the M-RFP inlet flow rate 8 is magnified due to the excess time of the control valve 7 and abnormal flow rate variation is caused. To prevent this, a gain and delay compensation circuit 9 is added to the M-RFP inlet flow rate 8. In other word, at the time when the inlet flow rate 8 begins to variate due to the control signal 6, flow rate signal is feedback immediately to the controller 5 to supress the variation of suply flow rate.

Abstract: PURPOSE:In a method of tying and cutting off the end of a wound linear material, to stabilize the cut-off position of the linear material, by causing a compressive strain in the linear material in the cut-off position, and applying a tensile force to the material to cut it off. CONSTITUTION:A nozzle 5 is moved to a winding position at a bobbin 1 in the spindle 4 of a winder so that a compressive strain is caused in a linear material, the winding of which is just started from a overlay-wound linear material 12. A tensile force is then applied to the linear material 2 between a pinch means 6 and a winding start terminal pin 1a so that the material 2 is broken off by tension. After that, the nozzle 5 is reciprocated so that a shearing strain is caused in the linear material 2 in a cut-off position and a tensile force is applied to the material. The material 2 is thus broken off by tension. According to this constitution, the cut-off position is stabilized independently of the cross-sectional form of the terminal pin 1a, and a tied portion not projecting as a whisker from the peripheral surface of the terminal pin is provided.

Title: Power system, discharge lamp lighting device, and lighting system
Inventor: MITA KAZUTOSHI
IPC: H02M7/48
Filed: 1994-03-31
Abstract: PURPOSE:To simplify the structure, prevent an inverter from malfunctioning due to surge voltage, reduce the cost, and accurately detect the life of a charge lamp without making an error in detection due to the surge voltage. CONSTITUTION:A resistance value of a surge voltage conduction element 29 decreases dramatically due to surge voltage applied to the element 29 and thereby a capacitor C21 is connected in parallel with a capacitor C20. As a result, large voltage is obtained by charging and discharging with the sum of electrostatic capacity of the two capacitors and enough voltage can be applied to an inverter 27 and thereby the switching operation does not get out of the class E oscillation operation and overcurrent does not flow in a transistor and there is no insulation breakdown of the device due to generation of heat. At the same time, the voltage across the surge voltage conduction element is conducted every half cycle by means of a diode D15 which is parallelly connected to the surge voltage conduction element. Due to this conduction, current which flows in the surge voltage conduction element is reduced and thereby generation of heat is prevented and the device is protected.
