Title: Charging equipment
Inventor: IKEDA YUSUKE
IPC: H02J7/04
Filed: 1987-04-30
Abstract: PURPOSE:To prevent recharge by the few number of parts by forming constitution in which a capacitor for smoothing for a rectifier circuit is removed. CONSTITUTION:When a charge type battery pack 21 is connected and a commercial power supply AC is connected, voltage is applied at both ends of a thyristor 23. Since a capacitor 26 is brought to a discharged state at that time, fixed voltage is applied at both ends of a resistor 24. The voltage is applied to a gate for the thyristor 23 through a resistor 27, and the thyristor 23 is turned ON and charging currents flow. Since the capacitor 26 smooths voltage at both ends of the thyristor 23 through the resistor 24, both-end voltage of the thyristor 23 does not take a negative value when the capacity of the capacitor 26 is sufficiently large, and the thyristor 23 continues an ON state. When charge proceeds and overcharge is brought, the temperature of a charge type battery body 21a is elevated, a temperature switch 21b is opened, and the thyristor 23 is turned OFF, and charging currents are interrupted.

Filed: 1990-04-23
Abstract: PURPOSE:To improve bursting resistance at the time of expansion by using such bag like woven fabric that a diameter in the 45 deg. bias direction to the warp direction of the woven fabric forming an air bag is smaller in a specific range than diameters in the warp and woof directions. CONSTITUTION:In view of the 45 deg. bias direction structure to the warp direction in bag like woven fabric 1, forming an air bag, having large effect on the bursting resistance of the air bag, a diameter d1 in the 45 deg. bias direction to the warp direction is set smaller in a specific range than a diameter d2 in the warp direction and a diameter d3 in the woof direction. That is, the diameter ratio of the bag like woven fabric 1 is set, although depending on the elongation of raw yarn forming the fabric 1, in such a way that the diameter d1 in the 45 deg. bias direction to the warp direction is 0.7-0.95, desirably 0.75-0.90, to the diameter d2 in the warp direction and the diameter d3 in the woof direction. This results in heightening bursting pressure at the time of bag expansion and also improving enclosing performance.

Filed: 1984-05-25
Abstract: PURPOSE:To arrange so that clear printing may be performed on whatever paper may be used in terms of thickness by providing a paper thickness detection means for detecting the thickness of printing paper and controlling printing speed based on a paper thickness detection signal. CONSTITUTION:If a paper thickness detection sensor 24 is pressed onto printing paper 4 on a platen 3, a surface pressure acts on a pressure-sensitive conductive rubber 25 and this voltage is inputted to a comparator 29. If the voltage value reaches a reference level by a variable resistor 34, a paper thickness signal SG1 is outputted resulting in the stoppage of a stepping motor 14. Then based on the number of drive pulses from a reference position to the stop position, CPU31 calculates an actual paper thickness of printing paper 4. Next, the stepping motor 14 is reversed setting a suitable print clearance. At the same time, the frequency of a drive pulse to a carriage drive motor 22 is changed according to a calculated paper thickness value. Thus an optimal moving speed is programmed.

Title: Drying device for adhered part with high frequency wave
Inventor: KUBOTA ATSUSHI
IPC: B29C65/48
Filed: 1978-08-31
Abstract: PURPOSE: Said device is equipped with a hydraulic cylinder for pressing the adherend that is bonded to the edge of a plate and together with a high-frequency heater in which the distance between the electrodes is made narrower than the width between the electrode and the cylinder, thus drying rapidly the adhesive.  
     CONSTITUTION: Said device for drying adhered parts with high frequency waves is composed of endless belt 7 for carrying the substrates, hydraulic cylinder 5, and high-frequency electrodes 6, etc. A plate 1 to which adherend 3 is bonded on the edge 2 is placed on the endless belt 7 and conveyed to a prescribed position. The hydraulic cylinder 5 operates to press the adherend 3 through wood material with fixed wall 8 and movable wall 9. Then, the movable electrode 2 of the high-frequency heater comes down and the movable electrode 12 and stationary electrode 10 hold the edge 2 of the plate 1. The high-frequency waves are applied to the edge 2 to dry the adhesive. At this time, the width between both electrodes is made narrower than that between the electrode and the cylinder 5 and so the electricity flows only the part between the electrodes and does not leak to other part, thus drying rapidly the adhesive.
