Title: Dust removal method for magnetic tape cassette
Inventor: KITA AKIHISA
IPC: G11B23/113
Filed: 1992-02-28
Abstract: PURPOSE:To provide a dust removal method for a magnetic tape cassette capable of easily and effectively removing dust generated at the time of welding of halves. CONSTITUTION:When a pair of halves 4 and 6 is ultrasonically welded, ionized air is blown into a case 8 from one opening port 20 of a pair of opening ports 20 and 22 in a condition that a lid is opened. Though dust is generated in the case 8 because of an ultrasonic vibration at the time of the half depositing, dust is eliminated easily and effectively by the blowing-in of air. Further, since the blown-in air is ionized beforehand, the electrification of dust stuck to the inside surface of the case 8, etc., is eliminated and thus, the effectiveness of dust erasing by means of air blowing is further improved.

Title: Nonaqueous electrolytic secondary battery
Inventor: KOBAYASHI MORIO
IPC: H01M10/60
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To suppress the abnormal temperature rise in a battery, and also improve safety and assembly by installing a refrigerant vessel in the center part of a battery case, and when the temperature in the refrigerant vessel exceeds a set value by releasing the sealing of the refrigerant vessel by a valve mechanism, to remove heat in the battery by the vaporization heat of a refrigerant. SOLUTION: A refrigerant vessel 20 is positioned in the center part of an electrode group 15 in a battery case 10. When an abnormal temperature rise occurs in the battery 10, an electrolyte in the battery is decomposed, also the electrolyte and the active materials of positive and negative electrodes 1 and 2 cause chemical reaction to generate a gas to suddenly increase its pressure in the battery case 10. This cleaves an explosion-proof valve 9 to blow off the gas outside the battery case 10 for reducing the explosion force of the battery. At that time, when the temperature in the refrigerant vessel 20, corresponding to that in the battery reaches a set temperature equal to or less than the oxygen separation starting temperature of the positive electrode active material, a temperature actuation valve mechanism 22 is released continuously.  The heat in the battery is absorbed by the refrigerant 21 to be vaporized and gasified into air, thereby preventing the temperature rise in the battery.

Title: Air cleaning apparatus
Inventor: HIRAI TOSHIHISA
IPC: F24F7/00
Filed: 1990-02-23
Abstract: PURPOSE:To electrically charge powder dust strongly accompanying the increase of sucked air amount and to enhance dust collecting efficiency of a dust collecting filter installed in an electric dust collecting apparatus by increasing applied voltage to a discharging part of an electric dust collecting apparatus with the increase of sucked air amount. CONSTITUTION:When air pollution is intense and a rotary speed of a motor 11 is risen corresponding to the output of a dirt detecting sensor and the amount of sucked air is increased, the voltage applied by a high voltage generating part 6 between a counter electrode, an earthing electrode and a discharging electrode of an electrical dust collecting apparatus becomes high. Consequently, polarization efficiency by the discharging part is heightened, so that powder dust is strongly discharged, and as a result, dust collecting efficiency of a dust collecting filter is improved. On the other hand, when the amount of sucked air is small, the speed (winding rate) of air passing the dust collecting filter is low and in this case, sufficient dust collecting efficiency is achieved only with the dust collecting filter.

Filed: 1982-03-18
Abstract: PURPOSE:To measure the output voltage of an ignition coil for an engine numerically  under the actual in-use condition without detaching a high-tension code, etc., by utilizing two kinds of branch resitances connected to a breaker contact in parallel. CONSTITUTION:The values of the resistances R1 and R2 of branch restance circuits are  so set that they are 5OMEGA when pulse signals shown in the figure are applied to input  terminals 7 and 8 of control electrodes of, for example, SCRs 5 and 6 to turn on the  two branch resistance circuits simultaneously for a parallel connection and 10OMEGA when  only the SCR5 is turned on. Consequently, a current is shunted to the branch resistance  circuits of 5OMEGA and 10OMEGA and a cut current when the breaker contact 2 is broken is reduced to lower each output voltage of the ignition coil 1; while ignition is not performed, the each output voltage of the iginition coil 1 is measured at a measurement  point P through a high-tension voltage sensor 9 and the difference Vd of each output  voltage of the ignition coil 1 when the current is shunted by the two kind of branch resistance circuits, i.e. resistances 5OMEGA and 10OMEGA is measured to find its gradient. Consequently, the maximum value of the ignition coil 1 is found as a linearly approximate  value from the operation of Vmax=VdXK (K; constant).

IPC: H03K17/13
Filed: 1979-04-12
Abstract: PURPOSE:To establish the zero voltage switch in which the conduction control of thyristor is made by photo transistor operated in unsaturation. CONSTITUTION:The transistor Tr33 is conducted at saturation state with the voltage increased at the output terminals 40, 41 of the fullwave rectifier 9. Accordingly, the thyristor 16 is non-conductive. When the voltage at the terminals 40, 41 is a value near zero, Tr33 is non-conductive. In this case, the light emitting diode 25 is in illuminating state, and when the photo diode 24 is activated, a current flows to the gate of the thyristor 16 to make conductive the thyristor 16. As a result, the voltage drop of the resistor 8 triggers the Triac 7 and make conductive it. Thus, the loop of the AC power supply 1, load 2, resistor 36, diode 12, thyristor 16, diode 11, resistor 8 and AC power supply 1, is formed which can supply a current to the load 2.
