Title: Tacky-polarizing-plate defective removing device automatic tacky-polarizing-plate sticking machine
Inventor: NAKAMURA TAKESHI
IPC: G02F1/1335
Filed: 1980-08-08
Abstract: PURPOSE:To simplify polarizing-plate working facilities by removing a defective part with minimum loss, by providng a means of peeling off only a polarizing plate, which is defective before being stuck among successive long-sized polarizing plates from a separator. CONSTITUTION:A defective removal device 10 consists of a peeling pawl 29 arranged over a polarizing plate tape 3 drawn forth from above a tool rest 22 and rocking around a pivot 28, a cylinder 30 rocking the peeling pawl 29, and a film 31 which is made of polyester, etc., and, while running right over the polarizing plate tape 3 in the opposite direction, receives a deflective polarizing plate 4a over the peeling pawl 29 to displace it. Once a sensor 25 detects a defective 3a, the cylinder 30 extends to rotate the peeling pawl 29 downward, thereby peeling the defective polarizing plate 4a from a separator 6. Consequently, only the defective polrizing plate is peeled off locally, so the waste of polarizing plates is minimized.

Abstract: PURPOSE:To reduce effects due to fading and to realize the system with a simple receiver by generating a signal having an amplitude proportional to a time interval of a reception signal subjected to amplitude limit at there reception side, restoring amplitude information and applying envelope detection demodulation. CONSTITUTION:A transmission section 7 adds an output of a SSB modulator 3 and an output of a carrier oscillator 2 by using an adder circuit 4 to obtain a SSB signal added with a carrier as the output. A signal reception section 15 uses a reception antenna 8 to receive a signal, which is subjected to downconvert and amplification and the result is inputted to an amplitude limiter 10. The limiter 10 suppresses the fluctuation of a reception level caused by fading to a constant amplitude and the output of the limiter 10 is given to a sawtooth wave generating circuit 11, from which a sawtooth wave proportional to the time interval of the output of the amplitude limiter crossing the zero point is generated. An undesired wave is eliminated from the output by a band pass filter 12. The output of the band pass filter 12 is detected by an envelope detector 13 and outputted to a demodulation signal output terminal 14.

Abstract: PURPOSE:To facilitate the operation for mounting a lens barrel onto camera main body, by making a lens operating member and the photgraphic lens barrel into one body provisionally in accordance with the operation for mounting the photographic lens barrel onto the camera main body. CONSTITUTION:Before a photographic lens barrel is mounted on a camera main body, the tip part of a key member 6 is projected from the barrel by the elasticity of a spring. In this state, when a lens-side count member 5 is pressed into a body-side mount member 15 of the camera main body and the lens barrel is rotated for the camera main body, a pressed moving piece 6a is pressed downward by the cam slope of a bayonet notch, and the key member is led into the barrel. In accordance with this operation, a detaining member 7 is turned clockwise, and the rotation of a distance ring 3 is stopped by a detaining part 7b.  Consequently, the user touches the distance ring 3 with fingers to rotate the whole of the lens barrel, thus mounting easily the barrel onto the camera main body.

Title: Supervisory system and method
Inventor: KINGDON JASON
IPC: G06Q20/00
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To find out an illegal action in a system by making blocks have a prescribed identification tag respectively, dividing them into plural subblocks which have the same tag while they are used and supervising final return to the source of electronic value with the identification tag and related value. SOLUTION: Tagging is performed to plural blocks that have independent value. This value is moved through an electronic value exchange system. It is inspected when it is returned to a person who executes a plan and holds tag information and the record of related value. Once the accounts of a block of specifically tagged value is settled, the existence of the other values which are identified with the same tag immediately exposes an illegal action. In such cases, the identification information of a tag includes information of a date and time or consists of them. By using tagging in this way, there is possibility that value inspection which simplifies independent quantity of electronic value may occur and illegal value is found out.

Title: Production of ni-base alloy hollow body
Inventor: TAKI MOTOJI
IPC: B22D13/02
Filed: 1985-05-24
Abstract: PURPOSE:To improve the quality of a product and to reduce the production cost thereof by forming a hollow body made of an Ni-base alloy by a centrifugal casting method and subjecting the hollow body to a diffusion treatment then to forging. CONSTITUTION:The Ni-base alloy is melted by melting in the atm. or in a vacuum and the melt thereof is formed to a hollow ingot by the centrifugal casting method. The defective parts on the inside and outside circumferences are cut away and the ingot is subjected to the diffusion treatment and is further molded by forging. Since the hollow ingot is formed by adopting the centrifugal casting method, the internal crystal grains are made finer than the crystal grains of a solid ingot. The fine casting defects are eliminated by the effect of centrifugal force and the forging time is decreased as the ingot is a hollow body. The quality of the product is thus improved and the production cost thereof is reduced.
