Title: Horizontal deflecting circuit
Inventor: SAWADA HISAO
IPC: H04N3/27
Filed: 1984-03-19
Abstract: PURPOSE:To apply a sawtooth wave signal having a prescribed frequency as well as the peak-to-peak value similar to the conventional one to a horizontal deflecting coil without doubling the value of EB, by using a conventional general-purpose horizontal deflecting coil. CONSTITUTION:A horizontal oscillation circuit 2 consists of an oscillation part which outputs a pulse signal having an oscillation frequency of 15.75kHz and a capacitor 5 which is connected to the part 3 via the 1st changeover switch 4 and serves as a converting element to 31.5kHz. Thus the oscillation frequency of the pulse output is changed to 31.5kHz from 15.75kHz when the switch 4 is turned on. The reactance of a horizontal deflecting coil 14 is set at I/4Ly=0.375mH when viewed from the side of a transistor 19. Then the actuation equal to that obtained with 31.5kHz is secured as shown in a table I by selecting the peak-topeak value of an ic at 9A. Thus a current Iy which flows actually to the coil 14 is set at iz=I/2ic and can be suppressed with 4.5A like to conventional 15.75kHz. Therefore the heat higher than the conventional level is never produced to the coil 14.

IPC: G01D5/18
Filed: 1984-03-19
Abstract: PURPOSE:To improve the resolution of a rotary angle and to enlarge the gap between a magnetic recording medium and a magnetic head, by constituting the magnetic head by MR elements, which are arranged at every (n+1/4)lambda or at every (n+3/4)lambda. CONSTITUTION:When a magnetic recording medium 1 and MR elements 41-44 at a 3/4lambda pitch are located at a position indicated in the Figure, an output voltage of Q0 is obtained. When the end surface of the magnetic recording body is moved to the right by lambda/4, an output voltage of Q1 is obtained. When the end surface is further moved to the right by lambda/4, the output voltage become Q2. Then an output B of a comparator is changed by one cycle. When the end surface is further moved to the right by lambda/2, the output voltage is changed to Q4 through Q3. After all, the output voltage of the comparator is changed by two cycles owing to the movement of the magnet recording medium 1 by one bit length lambda. When the same recording medium is used, the resolution of the rotary angle, which is more precise than the conventional medium by twice, can be obtained.

Title: Intra-device time setting system
Inventor: TABATA TAKASHI
IPC: G06F1/14
Filed: 1989-03-08
Abstract: PURPOSE:To attain the coincidence of time among plural devices by securing a constitution where the time setting destination side sets the reported time information at its own time counting mechanism and then reads out the information to report it to the time setting side and the time setting side obtains the correction value from its own time information and the time information reported from the time setting destination side and reports again the correction value to the device of the setting destination side. CONSTITUTION:N pieces of information processors 11 - 1N contain the time counting mechanisms 21 - 2N respectively and transfer the information with each other via a common communication channel 3. Then the occupation right of the channel 3 is temporarily to the device of the time setting side in order to prevent the delay of a time setting request due to the communication carried out among other devices. At the same time, the time setting destination side sets the reported time information at its own time counting mechanism and then reads out the information to report it to the time setting side. Thus the time setting side obtains the correction value from the difference between its own time information and the reported time information of the time setting side and reports again the correction value to the device of the time setting destination side. Thus the coincidence of time is secured with a small error among the mechanisms 21 - 2N of devices 11 - 1N connected to the channel 3.

Abstract: PROBLEM TO BE SOLVED: To read the change in detection temperature at a glance by changing recording colors per specified temperature zone on a temperature recording chart. SOLUTION: In a disc chart 10, specified temperature zones are respectively indicated by changing their recording colors. For example, black is used for a zone A of 10 deg.C or higher, red for a zone B of at most 10 deg.C blue for a zone C of 0 deg.C to -5 deg.C, green for a zone D of at most -5 deg.C. The respective zones A, B, C, and D are indicated by different color lines using different pressure sensitive paints. Thus, every time when the detected temperature is out of the specified temperature zone, the recording color is changed, so that the frequency of defrost operation or the time when the detected temperature is out of the specified temperature zone can be grasped simply.
