Title: Ribbon feeder mechanism
Inventor: SUZUKI TAKAYOSHI
IPC: B41J35/04
Filed: 1986-02-27
Abstract: PURPOSE:To enable the weight of a carrier to be reduced by using a fold-back mechanism 4 on a carrier to fold back a ribbon in two stages, each upper and lower without mounting a printing ribbon reel on the carrier in a transfer- type serial printer. CONSTITUTION:When a carrier 5 performs horizontal printing, a ribbon 11 is pulled out of a supply reel 1 and folded back through a guide roller 6-8 and a fold-back mechanism 4 to shift to an upper stage. Again the ribbon 11 contacts a head 3 again through the roller 8, and later reaches a non-rotating takeup reel 2 through the guide rollers 7, 6. In the meantime, when the carrier 5 performs a printing action to the left, a supply reel 1 does not rotate and the ribbon is taken up by the takeup reel 2 rotated with a rotary means at the same speed as said reel. In the meantime, printing is performed by a printing head 3 which is shifted to a lower stage. In either case, a ribbon 11 is relatively stationary with printing paper at a printing head 3. Thus the weight of the carrier can be reduced and printing by performed when the carrier moves horizontally with an overall improvement of printing speed.

Filed: 1983-03-16
Abstract: PURPOSE:To distribute efficiently bands by combining plural sheets of spectroscopic filter groups of multilayered films and alotting the widths of the wavelength bands occupied by the spectral outputs of respective colors according to wavelengths. CONSTITUTION:Photoelectric converters 901-906 receive respectively the output light from spectrally divided channel 1 - channel 6. An incident ray 910 to, for example, the converter 903 of the channel 3 transmits through dichroic mirrors C, B, and is reflected by a dichroic mirror A and thereafter the ray is taken out through an interference filter 913 for shaping band. The spectral output determined by the product of the reflection or transmission characteristic of the dichroic mirrors existing on each optical path and the transmission characteristic of the interference filter for shaping the band in the terminal part appears similarly in the other channels as well.

Title: Amplitude equalizer
Inventor: RIYUU TOSHIHIKO
IPC: H03H7/01
Filed: 1978-04-12
Abstract: PURPOSE: To obtain the flat delay characteristics complementarily as well as to secure variation of the amplitude-frequency characteristics through variation of the delay amount, etc. by giving the serial connection to two amplitude equalizers in which the delay circuit, phase-shift circuit and the attenuation or amplification circuit are provided between the branch circuit and the compound circuit.  
     CONSTITUTION: The 1st amplitude equalizer 1 branches off the input signals at signal branch circuit 11. One of the branched signals is sent to signal compound circuit 12, and the other is supplied to delay circuit 13 for delay and then attenuated or amplified 15 after phase shift at phase- shift circuit 14. And the output is applied to circuit 12 to be compounded with the signals sent from circuit 11. Then the output is sent to 2nd amplitude equalizer 2, and one signal branched off 11 is attenuated or amplified 15 to be sent to circuit 12. At the same time, the other signal is sent to circuit 12 after delay 13 and phase shift 14 and then compounded at circuit 12 to be then delivered. Thus, the flat delay characteristics is obtained through the complementary setting of the delay characteristics of both equalizer 1 and 2. At the same time, either at least one of the attenuation or amplification factor, the delay amount and the phase-shift amount is varied to change the amplitude-frequency characteristics.

Title: Ultrasonic flowmeter
Inventor: WADA ICHIROU
IPC: G01P5/00
Filed: 1978-04-13
Abstract: PURPOSE:To enable fluid of uneven distributions of velocities of flow to be readily coped with the by performing transmission and reception of acoustic waves through formation of different plural propagation routes and doing such things as removing the signals having been affected by channeling, air bubbles, etc. or averaging the respective signals. CONSTITUTION:The acoustic waves respectively oscillated from the first ultrasonic transducer part 2 in the P1 and P2 directions are reflected in the P3 and P4 directions by the reflecting faces M1 and M2 of the reflecting face parts 4 and 5 of the inside wall of a measuring pipe 1. In this way, the different plural propagation routes P1-P3 and P2-P4 are beforehand set, then even if air bubbles and foregin matter enter one routes, e.g., P1-P3 and the acoustic waves attenuate considerably, the transmission and reception of the acoustic waves by the propagation route P2-P4 are accomplished, thus producing no errors in measurement. If transmission is simultaneously accomplished with both propagation routes, the reception is accomplished simultaneously on the reception side and therefore if the receiving signals by both routes are summed, the large receiving signal is obtained even if there is some signal attenuation. If there is the effect of channeling, a lag occurs in the arrival time of both and therefore discrimination may be made based on this.

Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To reduce a circuit scale, reduce a mounting area and to realize a high speed operation by means of shorting delay time between elements by preventing circuits outputting the PN patterns of reference from becoming proportional to the number (n) of the bits of parallel signals. SOLUTION: Respective flip flop circuits 4-1 to 4-N output the sampled PN patterns of respective n-th bits with the operation result by (n-N+1) to n-bit post operation circuits 6-(n-N+1) to 6-n as a base by setting PN(1)-PN(N) as initial values. The comparison of reception data and the PN patterns of reference is executed by comparing data obtained by delaying reception data in a delay circuit 7 with the PN pattern of reference. Namely, the comparison of first to N-th buts is the comparison of the outputs of the flip flop circuits 4-1 to 4-N with the first to N-th bits of reception data outputted from the delay circuit 7. The comparison of (N+1)-th to n-th bits is executed by the comparison of the outputs of the operation circuit 6-1 to 6-(n-N) and (N+1)-th bits to n-th bits, which are outputted from the delay circuit 7.
