Title: Manufacturing device for imitation bamboo
Inventor: FURUKAWA KISHIKAZU
IPC: B21C37/16
Filed: 1989-01-30
Abstract: PURPOSE:To automatically manufacture an imitation bamboo having a bamboo node pattern by expanding a round pipe transferred by a prescribed length annually from its internal part to its external peripheral and forming a striped recessed groove in the intermediate part in the width direction of this annular expansion part. CONSTITUTION:One end Pa of the round pipe P made from Al, etc., is held by a holding apparatus 2. This holding apparatus 2 is provided with a diameter-expandable press-contacting member 29 and a push-draw operating member 21 and holds the round pipe P so that it cannot turn. A forming device 4 for an annular expansion part provided with the push-draw operating member 41 and an expansion part forming part 44 is inserted from the opening at the other end Pb of this round pipe P to form an annular expansion part on the external peripheral of the round pipe P. The recessed groove forming part 64 of an annular recessed groove forming device 6 is press- contacted with the intermediate part in the width direction of this annular expansion part while the recessed groove forming part 64 is revolved to form a striped annular recessed groove. Whenever this expansion part and the recessed groove are coupled to form one part, the pipe holding apparatus 2 holding the round pipe P is moved by a transfer 8 a prescribed length in the lengthwise direction of the round pipe P.

Title: Photographic film package
Inventor: OKADA KATSUMASA
IPC: B65D81/30
Filed: 1992-02-06
Abstract: PURPOSE:To provide a low-cost photographic film package such that external light entering from open end portions are surely blocked so that a used photographic film enclosed therein is not exposed. CONSTITUTION:Protruding streaks 14, 15 are formed by embossing at both ends of an opening 16 formed through a shielding envelope 4. Because the ends of the shielding envelope 4 where the protruding streaks 14, 15 are formed are increased in thickness, they are strongly held by shielding clips 5. The open end portions of the shielding envelope 4 are therefore held more strongly so that external light is prevented from entering the shielding envelope 4.

Filed: 1993-02-10
Abstract: PURPOSE:To enable the more efficient execution of region division and the efficient extraction of a specific region by executing the region division by clustering on a space, binarizing the regions, erasing background parts and extracting the specific region. CONSTITUTION:Respective pixels can be mapped on L=0 plane by one kind of projection operation along a semiellipse.

Title: Photoelectric switch
Inventor: ENDOU MASASHI
IPC: H01L31/02
Filed: 1980-02-22
Abstract: PURPOSE:To prevent erroneous operation due to noise signals, by integrating the detected signal by using the first synchronous pulses sychronized with a driving pulse and the second synchronous pulses whose phase is shifted from the first pulses, and by detecting the level. CONSTITUTION:The signal A which is the amplified signal of the detected signal R is detected to have a positive phase during the period the first synchronous pulses are present via a synchronous detecting circuit 6 and becomes the detected signal D1. During the period the second synchronous pulses are present, however, the signal A does not exist, and the detected signal D2 is not generated. In the case the amplified signal A which is a noise signal is generated from an amplifier 5, an integrating circuit 7 increases the level of the integrated signal I when the detected signal D1 is given, and decreases the level of the signal I when the detected signal D2 is given. The increase and decrease of the level is repeated, and the ON level La is not reached, and as a result, the noise signals are cancelled. The output Q of a Schmitt trigger circuit 8 remains at the low level L, and the erroneous operation is not generated. In this constitution, the erroneous operation due to noise signals can be prevented.

Title: Inverter type x-ray device
Inventor: DOMOTO TAKUYA
IPC: H05G1/32
Filed: 1991-02-15
Abstract: PURPOSE:To stabilize the voltage of an X--ray tube by feedback controlling a rectifier circuit on the input side of a resonant type inverter, keeping the input voltage of the inverter at optimum value, and suppressing noise or loss generated in a switch part of the inverter. CONSTITUTION:The wide voltage range inherent in an X-ray device is covered only by phase difference control of a resonant type inverter 3a, wherein the inverter phase difference theta is selected to around 0.3pi when the tube voltage Vh is in steady state with turbulence and power variation taken into consideration. When the phase difference is constant, the input voltage of the inverter 3a is approx. proportional. to the tube voltage. Therefore, the inverter input voltages Vinhi, Vinlo with max. and min. tube voltages are determined experimentally tube current by current, and in this interval the tube voltage Vh is proportionally calculated using the max. and min. tube voltages Vhhi, Vhlo. A rectifier circuit 2a is feedback controlled with the determined target inverter input voltage Vin. This reduces noise and loss of resonant type inverter 3a in the steady state, which should give a stable tube voltage.
