Title: Antibacterial sintered body and antibacterial filter using it
Inventor: YOSHITAKE SHUNICHI
IPC: C22C1/05
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To obtain a sintered body in which the revelation of antibacterial properties is early, also, the antibacterial effect is maintained over a long period, and the production is easy as well by controlling the content of silver oxide in a silver-silver oxide composite sintered body to a specified range. SOLUTION: In a silver-silver oxide composite sintered body, the content of silver oxide is 5 to 30 wt.%. The content of silver oxide is the value needed for maintaining effective antibacterial properties over a long period without deteriorating the initial revelation. In the case this antibacterial sintered body is used as a filter for city water, by the presence of silver oxide, the elution of silver ions having antibacterial properties is made easy, and also, by adjusting the content of silver oxide in the sintered body, the eluting rate thereof is controlled, and sufficient sterilizing power can be maintained over a long period.  Moreover, by forming it into a composite sintered body with silver, the high strength sintered body withstanding use over a long period can be obtd., and furthermore, by a simple method of sintering a silver oxide sintered body in the air, the desired sintered body can be obtd.

Title: Frame synchronizing circuit
Inventor: MACHIDA SHINICHI
IPC: H04L7/08
Filed: 1990-05-23
Abstract: PURPOSE:To shorten a time until frame synchronization is established by shifting input data by (N+1) bits when a pattern shows a noncoincidence pattern delaying>=(N+1), and shifting it by one bit when the pattern shows a delay pattern, delaying by 1-N bits. CONSTITUTION:A coincidence pattern decision circuit 14, a noncoincidence pattern decision circuit 15, and a delay pattern decision circuit 16 compare the pattern of the input data with a prescribed frame pattern and the delay pattern delaying>=three bits when a pattern detecting timing pulse from a frame counter 19 is inputted. When only a noncoincidence pattern decision signal is outputted from the noncoincidence decision circuit 15, the four clocks of an input clock are prohibited to output from a bit shift decision circuit 17 and an OR element 18. Thereby, the input data is set in a state where it is shifted by four bits. In such a way, it is possible to detect the pattern coinciding with the frame pattern or the delay pattern delaying<=three bits.

Title: Sound signal recoding circuit
Inventor: YAMAOKA KATSUMI
IPC: H04N5/92
Filed: 1988-05-31
Abstract: PURPOSE:To improve the accuracy and stability of a circuit characteristic as to a sound signal by executing a digital pre-emphasis processing to a digital sound signal before written to a memory. CONSTITUTION:The sound signal digital-converted by an A/D converter 10 is sent to a pre-emphasis circuit 12, and the pre-emphasis processing is digitally executed to the sound signal to be digital-converted there. Since the pre-emphasis processing reduces the influence of a high band noise as to the sound signal in a condition in which the sound signal is recorded to a recording disk Dc. it is the processing to raise a gain as the band of the components is high according to the frequency band of the sound signal. The pre-emphasis circuit 12 is composed of, for example, plural multipliers, adders, and delaying circuits. In such a way, by executing the pre-emphasis processing to the sound signal before time-base-compressed, the pre-emphasis processing can be executed in which the high accuracy and excellent stability are secured.

Title: Power circuit for base drive circuit
Inventor: TSUNODA HARUO
IPC: H02M1/08
Filed: 1990-05-24
Abstract: PURPOSE:To dispense with a current limiting resistor specified for a constant-voltage diode, by providing the constant-voltage diode of which a cathode is connected to a negative potential side bus line of a base drive circuit and an anode to a negative pole of a DC power source and by providing a smoothing capacitor between the cathode of the diode and a reference potential point on a control.

Moreover, a capacitor C3 is provided between the cathode of the diode ZD and a reference point which turns the potential of the cathode to be a reference potential GND. The point N of the base drive circuit 1 turns to be a negative potential by a terminal voltage E3(E3 = E2 - VZ) of the capacitor C3 in relation to the reference potential GND. In other words, the voltage E3 turns to be a reverse bias voltage for the drive circuit 1 and the value thereof is made variable properly by a change in the amount of voltage drop form a source voltage E2 due to a change in the Zener voltage VZ.

Title: Thermal transfer color printer and ink sheet used therefor
Inventor: OKA KENICHIRO
IPC: B41J31/00
Filed: 1995-05-31
Abstract: PURPOSE: To improve the quality of an inlay print by more increasing the energizing and deenergizing times of a thermal head for sequentially superposing ink layers of colors of one set of ink layers to be transferred by repeating the energizing and deenergizing of an ink sheet at the later arraying order of the one set of ink layers. CONSTITUTION: The longer the energizing time of a single heating resistor is at the times 20, 21 and 22 of recording yellow, magenta and cyan in the control waveform for energization to heat a thermal head at each line, the more the inks of the dots are melted, the viscosities are lowered, and the fluidities are improved, thereby improving the penetrability to a recess. The energizing times t11, t12, t13 of the one dots of the inks of the yellow, magenta and cyan have the relationship of t11<t12<t13. The deenergizing times T11, T12, T13 of the control waveforms at the time of recording correspond to cooling times. Thus, since the energizing heating times are increased more for the inks to be transferred later, they can penetrate the recess, and hence the color reproducibilities are not lost.

Then bus drivers 24 and 21 are turned on to give the feature data of the RAM 12 to the part 15 for calculation of the distance. At the same time, the feature data equivalent to the next template is transferred to the RAM 11 from the part 10. Here the reading action of the RAM is carried out at a high speed. While the transfer action is carried out at a low speed from the part 10.
