Title: Method and apparatus for quantitative judgment of distortion of x-ray image
Inventor: RAINAA HAINRIHI KOTSUPE
IPC: G06T1/00
Filed: 1994-04-28
Abstract: PURPOSE: To more exactly detect distortion by approximately calculating the coordinate values of picture elements in a distorted image from the coordinate values in a non-distorted image and determining the real coordinate values in the distorted image. CONSTITUTION: An X-ray source 1 and an X-ray image amplifier 2 at a cross section synthesizer are mutually oppositely moved through linear routes to a lot of position to form X-ray images. The X-ray images provided at various radiation source positions are overlapped so as to form a slice image and the slice image of an object placed between the radiation source 1 and the X-ray image amplifier 2 is sharply imaged but all the other areas of an object are made nonsharp on the other hand. In this case, a test object G is arranged on a fulcram plane 3 in order to quantitatively discriminate the distortion. Then, overlapping can be executed only after the conversion of test images to non-distorted output images A and A'. The distortion corrected output images are coincident with the test object G excepting for a reduced scale.

Title: Developing device for image recorder
Inventor: FUJITA AKIHIRO
IPC: G03G15/08
Filed: 1991-04-24
Abstract: PURPOSE:To obtain the developing device for the image recorder where an excessive load is not exerted on a rotational shaft by providing a torque limiter mechanism between an agitator and the rotational shaft. CONSTITUTION:The rotational shaft 18 is rotated only in the direction X by a driving gear 20 fixed to the rotational shaft 18. Toner is agitated by the agitator 12 inserted and held between a pressing spring part 22a and an auxiliary spring part 22b of a leaf spring 22 being rotated synchronized with the rotational shaft 18. If the excessive load is put on the agitator 12 here, since the rotational shaft 18 is rotated in the direction of X, the pressing spring part 22a of the leaf spring 22 deflects and runs off from the agitator 12, and the leaf spring 22 is rotated once and returned. In this case, because the rotational shaft 18 is continuously rotated in the direction X, the auxiliary spring part 22b is first brought into contact with the agitator 12, and the agitator 12 is jumped over. As the result, the leaf spring 22 is returned to an initial state of slackness, that is the normal state. The initial normal state is completely recovered here by eliminating the cause for the excessive load.

CONSTITUTION:When an amount of cold water flowing out from each external faucet Fc is higher than an amount of water fed from a water feed source 32 and the surface level of cold water in an inner tank 20b is lowered to the position of a two-dot chain line Lc, cold water on the inner bottom part of an outer tank 20a is automatically supplied with the aid of an internal circulating pump Pib as water flowing through communicating holes 22a and 22b to the inner tank 20b is effectively cooled. When the temperature of cold water in the inner tank 20b is increased, the internal circulating pump Pib is run under a state in which an internal circulating pump Pia is run to inject cold water in the inner tank 20b through an injection pipe 70 to the external tank 20a. Cold water in the external tank 20a is forced to flow in the same direction to melt water frozen on the inner periphery side of an evaporator 40 and produces low temperature cold water, which is automatically supplied in the inner tank 20b.

Abstract: PURPOSE:To compensate a dropout with least deterioration of a picture with a simple circuit constitution by providing a baseband signal dropout copensating means to compensate the dropout of a baseband signal converted from a chroma signal by a converting means. CONSTITUTION:A reproduced brightness signal separted from a reproduced composite video signal by a HPF 4 is supplied to a dropout detecting circuit 16.

Accordingly, the outputs of the switches 8, 18a and 18b come to be respective 1H preceding signals that is delayed for one horizontal scanning period by 1H delay circuits 9, 19a and 19b during the time dropouts are happening. In such a way, a signal including a dropout is interpolated by a 1-H preceding signal, then outputted.

Title: Digital broadcast receiver
Inventor: ICHIKAWA TOSHITO
IPC: H03J7/06
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To suppress the omission of information due to a filter by changing the frequency dividing ratio to keep the frequency offset within a prescribed level, when it exceeds this level. SOLUTION: It is decided whether the absolute value of the frequency offset value of an input signal that has been calculated at a control part 5 exceeds a prescribed quantity. If the absolute offset value exceeds the prescribed quantity, the error polarity is decided. When the frequency error is decided to be in the positive direction, the oscillation frequency of a receiver side being lower than that of a transmitter is signified. Thereby, the oscillation frequency of the receiver side is controlled to be made higher. That is, the frequency dividing ratio of a divider 9 which frequency-divides the output of a VCO 8 is changed by just one step portion so as to heighten the oscillation frequency of the VCO 8 by one step. When the frequency error is decided to be in the negative direction, the oscillation frequency of the receiver side is higher than that of the transmitted side.  Thus, the divider 9 is controlled so as to lower the oscillation frequency of the receiver side.

Title: Semiconductor manufacturing device and its method for transferring wafer
Inventor: OZAWA MAKOTO
IPC: B65G49/07
Filed: 1995-03-28
Abstract: PURPOSE:To improve throughput, simplify the device and suppress wafer contamination due to particles by transferring the wafer in the atmospheric air permitting the increase of a natural oxide film on the surface of the wafer to be within a range that does not cause actual trouble. CONSTITUTION:A wafer cassette 26 loaded with wafers 25 is stored on a cassette shelf 24. The wafer 25 taken out from the wafer cassette 26 in the atmospheric air is loaded on a boat 18. Since it takes approximately 15 minutes to transfer all the wafers 25 to the boat 18, the increase of the natural oxide film on the wafer 25 is not more than 1Angstrom  and the increase causes almost no influence to product manufacture. Then, inside of the load lock chamber 17 is filled with nitrogen gas, and the wafer 25 is transferred to the reaction chamber 15. Thus structure is simplified with one air-tight chamber, operation sequence of the device is simplified, and since nitrogen gas substitution is performed only for the load lock chamber, transfer cycle time is shortened and throughput is improved.
