Abstract: PURPOSE:To enable the possession of the steric feeling or beauty sense of a printing character, by making the color of an overlapped part different from at least one side color of its circumference in overpring. CONSTITUTION:An overlapped character printing mode is selected with a function key and each character buffer is secured in RAM at step S1. The shift amount between two characters is set at S2, a shift position setting routine is executed at S4 and the shift amount is established. A background character is stored in the first character buffer at S7. the character of an input key is stored in the second character buffer at S10 and printed at S11. A thermal head is returned by the amount which is one character minus x at S12, S13. It is changed at S14 to the printing color preliminarily determined and the background character stored in the first character buffer is printed at S15. Because the characters in the first and the second character buffers are printed thus by different colors, a striking printing mode can be obtained.

Title: Optical lens tray and optical lens contained in it
Inventor: NAGATA KOJI
IPC: G02B7/02
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To obtain an easily handleable optical lens tray by making the circumferential end surface of a flange part possible to touch the inner peripheral side surface of a second containing part. SOLUTION: At the time of containing an optical lens 1 into a lens containing part, an optical lens 1 is supported by an optical lens tray by making the lower surface of a flange part 3 touch the upper surface of a second containing part 7. In addition, a situation is arranged in which the circumferential side surface of the flange part 3 can touch the inner peripheral side surface of the second containing part 7. Consequently, when the optical lens tray receives an impact from outside, as the impact is transmitted from the inner peripheral side surface of the second containing part 7 to the circumferential side surface of the flange part 3, a transmission of the direct impact to the lens part 2 deciding the property of the optical lens 1 is stopped and a damage to the surface of the lens part 2 can be prevented.  Thus by limiting a place being in touch with the optical lens 1 in the optical lens tray to only the flange part of the optical lens 1, the impact from the outside is concentrated to the flange part of the optical lens 1.

Abstract: PURPOSE:To obtain clock recovery with high performance with simple constitution and to send other information by allowing a signal generator to modulate other information different from a data to be sent and to generate a signal while taking the multiplication of PR detection into account. CONSTITUTION:Taking the multiplication of partial response (PR) detection into account, a signal generator 9 is provided to the sending side (or receving side) at the PR(1, 0, &-1) detection to form a frequency fb/2. After a multiplexer 7 multilexes the signal and the output of a modulator 2, the result is impressed to a transmission line 3. The output signal from the line 3 is subjected to equali zation via an equalizer 4 and the detection of PR(1, 0, -1) is executed by a detector 5. On the other hand, the output of the line 3 is impressed to a band pass filter 8, from which a component near the frequency fb/2 is extracted. Since the pass band of the band-pass filter 8 is set narrow, a continuous wave with high S/N is obtained from the band-pass filter 8. Thus, clock recovery and tracking detection with high performance are attained and other information is sent by utilizing the frequency band (near fb/2).
