Title: Frequency conversion circuit and digital camcorder
Inventor: SUGIYAMA MASAYA
IPC: H04N5/372
Filed: 1994-11-22
Abstract: PURPOSE: To use an inexpensive CCD by providing each means which converts the output of the CCD driven by a clock signal A out of both clock signals A and B into the data synchronized with the signal B after the processing of both signals and then records the data on a magnetic tape by means of the signal B. CONSTITUTION: The 1st and 2nd clock signals CK1 and CK2 are used, and an A/D converter 6 and a digital camera signal processing means 7 applies the prescribed signal processing to the output of a CCD 1 which is driven by the clock CK1. A frequency converter means 10 Kenerates the intermediate video data at an intermediate point set between both adjacent sample points of the input video data through an LPF containing an output signal 7a of the means 7. Then an interpolation circuit of the means 10 performs the linear interpolation at a sample point synchronously with the clock CK2 and based on the input and intermediate video data. Thus a signal 10a undergone the linear interpolation is outputted. A digital recording/reproducing processing means 3 processes the signal 10a by means of the clock CK2 and then records and reproduces the signal 10a on a magnetic tape 5.  Thus it is possible to use a highly reliable and inexpensive CCD which can improve the accuracy of the output image data.

Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain good touch feels varying with compass by providing keyboards with pseudo action devices for imparting different loads thereon. SOLUTION: A controller 20 discriminates whether keytouchs are detected by key sensors 4 or not when sound production processing is started. This controller determines a time difference from the differences in the on-times between the two contacts of the key sensors 4. Next, the controller calculates the output values of control signals (voltage waveform signals, current waveform signals etc.) to an electronic sound source 80 in accordance with these time differences according to the key numbers of the touched keyboards 2. The prescribed waveform signals are obtd. in accordance with the key numbers of the touched keyboards 2 and the key numbers and an electronic sound source 80 is controlled in accordance with the waveform signals to produce sounds from a speaker 90. The sound production from the electronic sound source 80 is stopped when the key release is detected.  Then, even if the different loads are imparted on the keyboards 2, the output values in the case the respective keyboards 2 are touched with the same intensity are controlled uniformly among the keyboards 2.

Abstract: PURPOSE:To obtain a fixing device by which an operator does not get burned even when he touches a fixing frame and where image quality is not deteriorated caused by the fallen fiber of flocked fibers by providing a minute projection or a rib on the surface of the frame of the fixing device which the operator touches with his hand. CONSTITUTION:The pointed ribs 12d, 12d,... are provided on the surface 12b which the operator tends to touch in the case of jamming processing, because a fixing roller 13 and a pressure roller 14 which generate heat in the case of operation are fixed on the frame of a mold member in the fixing device 12. Thus, the operator does not get burned even when the operator touches the frame 12, because the contact area is small. The temperature in the fixing frame 12 goes near to 100 deg.C. However, only the heat equal to that in the case of flocking the fibers is felt by setting the ribs whose height is 2mm and whose tip is R0.3 at the pitch of 5mm or within that pitch. The minute projection 12C is provided instead of the rib. By providing the projection whose height is 2mm and the tip is R0.3 at the pitch of 5mm or within that pitch, the effect equal to that in the case of providing the rib is obtained.

Title: Printer and method of printing
Inventor: OTSUKA NAOJI
IPC: B41J2/21
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of color variation due to a scanning direction even when executing bi-directional color printing by a different quantity of ink. SOLUTION: Two sets of recording heads capable of producing relatively large dots of inks of cyan(C), magenta(M) and yellow(Y) and relatively small dots thereof, respectively are symmetrically provided in the scanning direction. The orders of C and M to be applied to a secondary color of pixel by each of the dot sizes are to be symmetric orders (C→M, M→C). Therefore, as the applying orders of inks of any dot sizes to be applied to the secondary color pixel are symmetric with each other, the applying orders are not different from each other even when the pixel is formed in any scanning in outward and inward passages. As a result, it is possible to suppress occurrence of color variation due to the applying order of the inks.
