Title: Marker agent for mri and marker
Inventor: HIRANO HIROMICHI
IPC: A61B5/055
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To enable the use of a marker agent sensing both at the time of photographing of the longitudinal relaxation emphasis image and transverse relaxation emphasis image of an MRI. SOLUTION: The gelatinous marker agent is prepd. by adding Gd-DTPA which is the conjugated matter of gadolinium of a paramagnetic material and DTPA of a chelate agent at a concn. of 1mol/l into gelatin dissolved to attain a concn. of 5wt.% and making the entire part uniform. This marker agent is dissolved and is packed into a fine tubular vessel made of polytetrafluoroethylene having an inside diameter of 2mm and an outside diameter of 3mm and the end of this vessel is sealed, by which the internally gelatinized marker is obtd. This marker agent and marker emit signals by sensing both of the longitudinal relaxation (T1 ) emphasis and transverse relaxation (T2 ) emphasis. These signals appear distinctly on the photographed topographic images.

Title: Double conversion tuner
Inventor: KAYAGAKI YOSHINORI
IPC: H04B1/26
Filed: 1987-06-29
Abstract: PURPOSE:To prevent back talk by presetting the value of the 1st intermediate frequency so that the frequency of the 1st local oscillator in receiving an input signal with a minimum frequency in the reception frequency range is twice or over the input signal of the highest frequency in the reception frequency range and its value does not exceed 1GHz. CONSTITUTION:The 1st intermediate frequency f1P is selected so that the frequency f1 of the 1st local oscillator 4 in receiving a signal of the lowest frequency fRF1 in the reception frequency range fRF1-fRFn is twice or over the signal of the highest frequency fRFn in the reception frequency range. A RF signal (signal band W) received from the input terminal 1 is converted into the 1st local oscillation frequency f1 by the 1st mixer 3 and the difference component (signal band W') is fed back to the input side to form a back talk component. However, the lowest frequency (f1-fRFn) of the difference component is at the outside of the band fRF1-fRFn of the input band pass filter 2, the difference component is attenuated by the input band pass filter 2. Thus, back talk is blocked without adding any new circuit while utilizing the amplification element within 1GHz.

Abstract: PURPOSE:To obtain the chuck, which does not damage a wafer and combines a vacuum chuck and a Bernoulli chuck, by properly using a suction from a negative pressure introducing pipe and the injection of an air current from an air- current introducing pipe and tapering the inner edge of the nose of an attracting head. CONSTITUTION:When a valve is changed over and the wafer is sucked under vacuum, negative pressure is introduced to the recessed section of the lower surface of the head 11 from the pipe 13, and the tapered surface 12 of the head forms angles of 2 deg.-5 deg. together with the top surface of the wafer 1, thus attracting and holding the wafer under the state of a linear contact in a fringe shoulder section. Accordingly, the surface of the wafer is not damaged. When the valve is changed over, a suction under vacuum is stopped and N2 gas is introduced 18, N2 flows on the surface of the wafer 1 along a plate 17, and the wafer is chucked by buoyancy. A distance (t) between the wafer and the plate is determined according to the flow rate of N2. A chuck surface and a wafer surface are kept parallel in either case of the vacuum chuck or the Bernoulli chuck by the action of a spherical bearing 14. The chuck is suitable for receiving or feeding the wafer from or to the upper section of the heating plate of a CVD device.

Title: Magnetic recording and reproducing device
Inventor: HAMA MINORU
IPC: G11B15/46
Filed: 1982-09-13
Abstract: PURPOSE:To reduce the noise of modulation with simple constitution, by bringing a modulation noise reducing part into contact with a tape in cooperation to a magnetic head in a record or reproduction mode. CONSTITUTION:A scrape filter 15 serves as a modulation noise reducing part. The 1st and 2nd rolls 17 and 20 are attached pivotably to shafts 18 and 21 on a base 16 interlocking a head mechanism part, and these rolls are connected with a belt 23. In a record or reproduction time, the filter 15 is also shifted toward a cassette in cooperation to the head mechanism part. Then the roll 17 is in contact with a tape 6. Therefore the mechanical loss of the tape 6 is increased to reduce the modulation noise by decreasing the length between nodes of the tape 6 and increasing the oscillation frequency. In addition, the insufficient damping of the roll 17 is compensated by the roll 20 owing to the connection with the belt 23. Thus the effect is improved.

Abstract: PURPOSE:To facilitate the attachment or a wheel to a body frame of a bicycle in such a condition that a removal checking tool acts. CONSTITUTION:A removal checking tool 9 for preventing a wheel W from coming off from the vehicle body frame F is attached to a cylindrical axle 4 by means of a support tool 11 and a lock nut 12 so as to be slidably switchable between an operative position A where an acting end part 9a of the tool 9 covers over a wheel attaching part 13 on a vehicle body frame F and a non-operative position B where the acting end part 9a can be removed from the wheel attaching part 13. When the removal checking tool 9 is switch to the nonoperative position B, the removal checking tool 9 is self-sustained by a pressing action given by the urging force of a Belleville spring 14 so that a manipulation for manually supporting the removal checking tool 9 at the nonoperative position is not required. When the wheel W attached to the vehicle body frame F is rotated, a cam type attaching means 9b incorporated to the removal checking tool 9 makes contact with spokes 15, and accordingly, the removal checking tool 9 can be automatically switched to the operative position by a torque from the wheel W.

Title: Scintillation camera
Inventor: MATSUYAMA TSUNEKAZU
IPC: G01T1/208
Filed: 1984-07-31
Abstract: PURPOSE:To compensate easily a drift of a circuit system due to a secular change of a photomultiplier and a variance of surroundings by providing a scintillator, the photomultiplier, a preamplifier, etc. CONSTITUTION:The radiation passes a scintillator 1 and is sent from a photomultiplier 2 to an adding circuit 4 through a preamplifier 3 to obtain a position signal and an energy signal. When the scintillation light in a certain position occurs, the output of the photomultiplier 2 is inversely proportional to the length from this position to the photomultiplier. Since the total sum of outputs of the photomultiplier 2 corresponds to the energy of the incident radiation, the total sum signal is obtained as the energy signal. Meanwhile, a microcomputer 7 is operated at intervals of a certain time to output a cut-off signal to the photomultiplier 2, and the output is sent to an integrating circuit 6 through the preamplifier 3 and the circuit 4 and is integrated and is stored in a sampling and holding circuit 8. The integral value of the circuit 8 is subtracted from the output of the circuit 4 by a subtracting circuit 5. Thus, the drift is cancelled to perform compensation easily.

Filed: 1980-11-14
Abstract: PURPOSE:To increase the compression efficiency, by transmitting the state of data and number of consecutiveness through coding, when the data of consecutive blocks are all the same, in the data compression of each block. CONSTITUTION:One optical scanning region on an original 1 is of band phase, which is split into video elements. The contrast information is stored in a memory B1. A counter K1 counts a clock pulse reading out the memory B1 one by one bit.
