Filed: 1989-05-29
Abstract: PURPOSE:To obtain the simplified fading generator which can confirm a receiving equipment, and also, can be carried easily by turning ON/OFF a contact of a high frequency relay by an output of a pulse generator, allowing an inputted RF signal to pass through when the contact of the high frequency relay is turned ON, and varying the strength of an electric field by a converting means at the time when the contact is turned OFF. CONSTITUTION:An astable multivibrator 3 outputs a pulse signal having a period determined by values of a capacitor 32 and resistors 33-35. This pulse signal is applied to a high frequency relay 2, and the high frequency relay 2 turns ON/OFF the contact in accordance with the pulse signal. In accordance with ON/OFF of this contact, an input RF signal is switched as to whether it is outputted as it is to output terminals 51, 52 or passes through a resistor 4. In case of passing through the resistor 4, the strength of an electric field of the input RF signal is varied in accordance with a value of the resistor 4. Accordingly, the input RF signal is fluctuated by a period determined by the astable multivibrator 3 by a variation portion by which the strength of an electric field is determined by the resistor 4. In such a way, a fading generator which is suitable for confirming an operation of a mobile radio receiving equipment, which is small in size and can be carried easily is obtained.

Title: Driving method of ingot drawing roll in horizontal continuous casting machine
Inventor: HONDA AKIRA
IPC: B22D11/128
Filed: 1979-10-17
Abstract: PURPOSE:To freely adjust drawing and pushing-back cycles of an ingot by giving ingot pushing-back rotating force at all times to an ingot drawing roll and giving drawing rotating force overcoming the ingot pushing-back rotating force at the drawing. CONSTITUTION:An ingot drawing roll shaft 9 is held applied with rotating force by means of a drive motor 10 for ingot pushing back in the direction of pushing back the ingot. A crank shaft 1 is rotated by a drive motor 3 for ingot drawing and its revolutions are transmitted via a crank rod 6 to an intermediate shaft 4. An intermittent rotating gear 7 is mounted to this intermediate shaft 4, and is meshed with a drive gear 11 mounted to the drawing roll shaft via a clutch 12. The drawing direction rotating force of the intermittent rotating gear 7 is set larger than the pushing-back direction rotating force of the drive gear 11. As a result, despite the exertion of the pushing-back direction rotating force at all times upon the drive gear 11 at the drawing, the rotating force of the intermittent rotating gear 7 overcomes  said force and rotates in the drawing direction.
