Title: Traffic control sign installing metal fitting
Inventor: KOBAYASHI SOUJI
IPC: E01F9/627
Filed: 1992-02-21
Abstract: PURPOSE:To absorb a sharp bent angle and a twist. CONSTITUTION:A main body 15 is installed in a support metal fitting 10 so as to be capable of making horizontal turning motion freely, and a movable body 19 is installed in the main body 15 so as to be capable of making turning motion freely, and they are constituted so as to be bent in two stages. A V shape notch part 22 is formed in a spherical body part 20 of the movable body 19, and a twist is reduced to its original position by means of a guide pin 23 and this notch part 22. Thereby, since this traffic control sign installing metal fitting can be bent in two stages, even if a sharp bend is applied, troubles are not caused, or even if a twist force acts upon it, it can be restored to its original condition, so that a traffic control sign is not left still in a twisted condition.

Title: Cooler for motor
Inventor: SUDA TOKU
IPC: H02K9/19
Filed: 1992-02-21
Abstract: PURPOSE:To effectively cool a stator which tends to have a highest temperature in a motor and to efficiently cool the motor in response to a driving state of the motor. CONSTITUTION:A controller 33 is mounted in a pump 31 for supplying cooling refrigerant to a cooling refrigerant supply passage 27 provided in a driving shaft 15 at which a cooling refrigerant injection hole 29 is provided at a position opposite to a winding lug 23. When a motor 10 is rotated, the refrigerant supplied to the passage 27 is injected from the hole 29 by a centrifugal force to be applied to the lug 23, and a stator 13 is directly cooled. Since a quantity of the refrigerant to be discharged from the pump 31 is controlled so as to follow up a composite loss amount of a motor 10, an injection amount of the refrigerant from the hole 29 faithfully follows up the composite loss amount of the motor 10, thereby controlling a cooling capacity corresponding to a quantity of generated heat.

Title: Method for disposing of abandoned magnetic card
Inventor: INO TOSHIO
IPC: G11B5/80
Filed: 1988-02-19
Abstract: PURPOSE:To prevent the illegal use of an abandoned magnetic card by erasing the data track, with the clock pulse track being left as it is, when the magnetic information encoded on the abandoned magnetic card is erased. CONSTITUTION:A passenger ticket card is provided with a clock pulse track 30 and data track 20 and the data encoded on the card are not reproduced unless pulses are inputted. On the other hand, even when pulses are inputted to the clock pulse track 30 and the recorded content of the data track 20 is reproduced, the reproduced data become '0' if the recorded content is '0'. Therefore, when only the data track 20 is erased at the time of disposing of an abandoned magnetic card, the abandoned magnetic card can be distinguished from other abnormal tickets (such as un-encoded tickets, tickets whose data are wrongly erased by means of a magnet, etc.). Since the abandoned magnetic card becomes distinguishable from other abnormal tickets, the illegal use of the abandoned ticket can be prevented effectively.
