Title: High voltage device for x-ray
Inventor: SASAKI OSAMU
IPC: H05G1/32
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To miniaturize a high voltage transformer by obtaining a mean value of the current in a primary winding of the high voltage transformer, and by feeding the mean value back to the positive and the negative switching width of an inverter to control the mean value to be zero. SOLUTION: When a positive or a negative mean value output generates from a mean value circuit 64 due to the magnetic distortion in a high voltage transformer 15, one of the input to the voltage to pulse width converter 51, 52 becomes larger and the other input becomes smaller. In response to this, a positive switching width in an inverter circuit 14 becomes longer, and a negative switching width becomes shorter. Thus, a feedback to control the distorting current detected by a current detector 63 and the means value circuit 64 to be zero is made, and a control not to always generate the magnetic distortion is done.  Consequently, when a material with relatively small saturated magnetic flux density, such as ferrite, is used as a core of the high voltage transformer 15, the number of turns for the primary winding can be made smaller, and the high voltage transformer 15 can be miniaturized as a result.

Title: Display of exposure controlling value
Inventor: OOHASHI HIDEYO
IPC: G03B17/18
Filed: 1982-02-03
Abstract: PURPOSE:To simplify recognition, and also to decide at a glance the remaining quantity of a  battery or a replacement time, namely, a life, by constituting a titled display so that voltage is  displayed on a dot display part in case when the voltage of an power supply battery is prescribed voltage or above, and an alarm such as flashing, etc. is given in case when it is below  prescribed voltage. CONSTITUTION:An output of a photometric circuit 1 and an output of a power supply battery  circuit 2 are selectively switched by a switching circuit 3, an analog signal from the switching  circuit 3 is converted to a digital signal VAD by an A/D converting circuit 4 and is applied to  a central processong unit 5, and digital operation is executed so that the digital signal VAD is  suitable for display. A display 6 containing a digital display part 6a and a dot display part 6b  is displayed as shown in a figure (a) at the time of photometry, and is displayed as shown in  a figure (c) at the time of battery check. In this way, by utilizing a digital operating circuit of  a digital exposure value controller, and the display 6, the voltage of a power supply battery is  displayed in bar graph, displayed in dot or digitally displayed, and in case when it is prescribed voltage or below, it is alarmed by flashing, etc. Therefore, in case when the voltage of  the power supply battery is prescribed voltage or above, a digital operation result can be displayed almost analogously by the bar graph display or the dot display, and in case when it is  prescirbed voltage or blow, an alarm can be executed by flashing, etc., therefore, the recognition is simplified.

Title: Bushing pocket for high power current
Inventor: KOJIMA TAKESHI
IPC: H01F27/04
Filed: 1977-02-18
Abstract: PURPOSE: To provide the subject bushing pocket wherein the corner portions of the surface and side plate of a cover pocket are formed into a curvature to reduce the eddy-current loss thereby to reduce the local overheating at the pocket corner portions.  
     CONSTITUTION: The magnetic field due to a loop current flowig concentrically to the lower end of the case of a phase separation bus 8 becomes smaller as it is apart away from the lower end of the case, and hence the occurrence of eddy-current loss is also reduced. Therefore, the corner portion of the surface of the pocket cover 1 and side plate 2 thereof has a curvature structure. For this reason, particularly the edge part of the conventional pocket corner portion of rectangular construction is eliminated, and the positions of the corner parts 22 and 23 are substantially separated from the lower end of a box 8, thereby reducing the eddy-current loss. For this reason, in the high power current bushing pocket the local overheating of the corner portion particularly liable to be overheated on the cover surface

Title: Magnetic recording and reproducing head device
Inventor: JITSUKAWA TAKUJI
IPC: G11B5/265
Filed: 1980-02-13
Abstract: PURPOSE:To prevent the influence of positional slippage of the track, by arranging the head used for recording and reproducing and the erasing head so that the recording track width is larger than the reproducing track width. CONSTITUTION:The first recording and reproducing magnetic heads 15-18 and the second recording and reproducing magnetic heads 19-22 are so arranged that gaps are parallel, and erasing heads 23-27 are arranged between the first recording and reproducing magnetic heads and the second those, and they are shielded from one another by shielding plates 28 and are stored in cover 29. The interval of arrangement of erasing heads is smaller than the gap width of the first and the second recording and reproducing magnetic heads 15-18 and 19-22. Consequently, for example, when recording is performed by magnetic head 15, edges are erased by erasing heads 23 and 24 in the track width to make the recording track width narrower by these components, and it is reproduced by magnetic head 19 of a wider width, so that positional slippage is ignored if slippage of the recording track is within the range where it is included in the reproducing track.

Title: Frame synchronizing circuit
Inventor: SHIRAI KAZUHIKO
IPC: H04J3/06
Filed: 1988-01-29
Abstract: PURPOSE:To suppress the increase of hard quantity even to the repeating signal of a specified fixed pattern and to execute synchronous leading-in without tail by providing a memory to store the generating condition of a coincident signal and a dissident signal instead of a counter to count these signals. CONSTITUTION:Whether the condition of a frame bit is satisfied in correspondence to respective bit positions or not is checked by plural synchronization detecting parts 1 and the generating condition of the coincident signal and dissident signal, which are outputted from the correspondent synchronization detecting part 1, is stored in plural memory parts 2. How different bit number is from the generating condition of the coincident signal and dissident signal to be expected to the frame bit position for the contents of the correspondent memory part 2 is detected by plural difference detecting parts 3. Then, a deciding part 4 receives all the outputs of the difference detecting parts 3 and decides whether the difference is over one constant or not in the other bit position excepting for one bit position. Thus, even to the repeating signal of the specified fixed pattern, the increase of the hard quantity is suppressed and the synchronous leading-in can be executed without fail.
