An abutting part 4 is so disposed as to limit the rotation of a paper presser holder 1 in the direction that the paper presser roller 3 separates from a paper feed roller 2. In this manner, when the thickness of the printing paper 7 is not less than a fixed value, the paper presser holder l abuts against the abutting part 4. In this case, a pressing force of the paper presser roller 3 against the printing paper 7 and the paper feed roller 2 is not less than a pressing force when the thickness of the printing paper 7 is less than the aforesaid fixed value and has a positive correlation to the total of the displacing amounts of the paper feed roller 2 and the paper presser roller 3.

Abstract: PURPOSE:To obtain good image quality generating no blotting of a picture element at the time of high-density printing and not interfered by the density of the adjacent picture element by eliminating the dropouts of picture elements at the time of low-density printing, by providing an auxiliary heat generator element narrower than each main heat generator element between a plurality of main heat generator elements. CONSTITUTION:Because a predetermined drive current is supplied to auxiliary heat generator elements 8, 8 at the time of low-density printing and the auxiliary heat generators 8, 8 generate heat, the temp. characteristic of thermal recording paper in the horizontal direction X comes to the state shown by A and predetermined temp. is kept even at the part corresponding to the space between main heat generator elements 2a, 2b, that is at the space between picture elements and no dropout is generated. At the time of high-density printing, no drive current is supplied to the auxiliary heat generator elements 8, 8 and, because said auxiliary heat generator elements 8, 8 have extremely good heat conductivity, the heat between the main heat generator elements 2a, 2b, that is, between the picture elements is dissipated through said auxiliary heat generator elements 8, 8. Then the temp. characteristic of the thermal recording paper in the horizontal direction X is shown by C with no interference acting between the adjacent main heat generator elements 2a, 2b and the blotting of the picture element is improved without being interfered by the density between adjacent picture elements. Accordingly, printing high quality is obtained.

Abstract: PROBLEM TO BE SOLVED: To easily obtain the dew point of gas by calculating a steam partial pressure value from a saturation steam partial pressure value and measurement humidity and obtaining a temperature that becomes a dew point corresponding to the partial pressure value from a data table. SOLUTION: When a valve 5 of a switching valve 26 is located at a position being shown in Fig. 2, a drying process is executed by a B cylinder 4 and a pressurizing process or a reproduction process is executed by an A cylinder 3. More specifically, wet compression air being supplied to a dehumidifying device is guided to a port C of the switching valve 26 via an introduction path 30 from an introduction port 10 of an inlet head 15, and is further guided into the B cylinder 4 from a B cylinder communication path 32 via a port (d). While the wet compression air passes inside the B cylinder 4 from a lower portion to an upper portion, moisture is sucked and dehumidified by an adsorbent 17 that fills here. Then, a check valve 18B that is provided at its top is pushed up for guiding to a supplying path 20 of the outlet head 5, and is further supplied from a support port 9.  Also, one portion of dry air from the upper opening of the B cylinder 4 is guided to a purge chamber 22, flow rate is reduced, and moisture through the adsorbent 17 is eliminated.

Title: Scintillation camera
Inventor: TABUCHI HIDEHO
IPC: G01T1/161
Filed: 1988-07-18
Abstract: PURPOSE:To improve the imaging of a small organ such as the head by increasing sensitivity by about two times by setting a collimator to a unidimensional converging type one and making the converging distance thereof larger than the distance between said collimator and the opposed detector. CONSTITUTION:Unidimensional converging type collimators 50a-50d are made parallel to a center-of-rotation shaft OR1 and formed so that the converging positions thereof become the surface positions 51a-51d of the opposed collimators. In this case, the effective visual field of a single photon emission CT constituted of a plurality of detectors becomes the inscribed circle formed by the lines connecting the converging positions 51a-51d of the collimators 50a-50d and both ends of the collimators and becomes smaller than that in the case of parallel collimators. However, since detection sensitivity is increased by about two times, this camera is suitable for the imaging of a small organ such as the head or an infant.

Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a spread spectrum communication receiving device whereby carrier wave is surely reproduced and the simplification and the stable operation of a circuit are obtained. SOLUTION: The peak part of a self correlative signal is taken-out by a second automatic gain control amplifier for an inverse spreading signal which is obtained in an SAW(surface acoustic wave) matched filter 14, it is given to an SAW delay line 18 and an electric signal with the same phase as that of the peak part, which is reference information for reproducing carrier wave, is repeatedly outputted for a prescribed time. Then, the outputted signal is given to a carrier wave reproducing circuit 16 so as to reproduce carrier wave. Therefore, even when the appearance time of the peak part is short, the signal with the same phase as that of the signal of the peak part is continuously outputted a thereafter so that carrier wave is surely reproduced.  Carrier wave is also correctly reproduced and outputted since the recognition of synchronization is successively executed without waiting the appearance of the succeeding peak part.
