Title: Dpcm coding circuit
Inventor: MURAKAMI YOSHIHIRO
IPC: H04N11/04
Filed: 1979-05-17
Abstract: PURPOSE:To secure the steady circuit operation although the sampling frequency may be three times as much as the chrominance carrier, by decreasing the number of the circuit elements of the loop circuit relating the predictor functioning as a pre- predictor. CONSTITUTION:The video signal received at input terminal 11 is turned into the digital output of A/D converter 1 via the sampling signal sent from terminal 13 to reach quantizer 3. The desired PCM output is obtained through output terminal 12 by making the output of quantizer 3 pass through bit converter 4. At the same time, the output of quantizer 3 is applied to adder 6. The output of adder 6 is applied to 2-dimensional predictor 10, and the output of predictor 10 is applied to adder 16 via delay circuit 9. On the other hand, the output of predictor 15 is applied also to adder 16, and the output of adder 16 is applied to adder 7. Pre-predictor 8 is included in the loop circuit in which substractor 2, equalizer 3, predictor 8,  adder 7 and latch circuit 5 are connected in the sequential and circulating way.  Accordingly, the time required for operation of the loop circuit can be shortened by  decreasing the number of the circuit elements, thus securing the steady operation of  the circuit even with the high sampling frequency.

Title: Production of 6-aminopenic anic acid
Inventor: MORITA YUTAKA
IPC: C12N9/84
Filed: 1983-03-05
Abstract: PURPOSE:To obtain 6-aminopenicillanic acid in high yield and purity, by using a variant strain, sensitive highly to a beta-lactam antibiotic substance, and obtained by subjecting the beta-lactam antibiotic substance to variation treatment. CONSTITUTION:An antibiotic substance, sensitive highly to beta-lactam antibiotic substance, and obtained by subjecting the beta-lactam antibiotic substance to the variation treatment, e.g. a strain sensitive highly to the beta-lactam antibiotic substance, and obtained by subjecting coliform bacillus Escherichia coli IFU 3366 strain to the variation treatment, is used to produce 6-aminopenicillanic acid. The high sensitivity to the beta-lactam antibiotic substance results in the high permeability of cell membranes to penicillins as a substrate and 6-aminopenicillanic acid as a product. Thus, the high permeability permits easy entry of the penicillins brought in contact with microbial cells into cells. Then, the penicillins are subjected to the enzymic reaction, and converted into the 6-aminopenicillanic acid comes out of the microbial cells. Therefore, the high permeability provides increased activity per unit weight of the microbial cells.

CONSTITUTION:A coating compsn. is obtd. by incorporating a fluorinated copolymer (A) wherein the fluorine content based on the fluoroolefin unit is 10wt.% or more and which is soluble in a solvent and has a curable part (pref. a fluorinated copolymer wherein a fluoroolefin and vinyl ether are incorporated as comonomer components and which has an inherent viscosity measured in tetrahydrofuran at 30 deg.C of 0.05-2dl/g and is soluble in a solvent) and a polyfunctional organosilicon compd. (B) contg. an acyloxy group directly bound to a silicon atom (e.g. methyltriacetoxysilane). As this compsn. can be cured in a one-package form and does not need a baking operation at high temp., it makes the coating operation quite easy and exhibits an extremely excellent adhesive properties on a substrate such as glass or metal and excellent weatherability and heat resistance. In addition, it exhibits an effect of shortening the curing time.

Title: Ink jet recorder
Inventor: TERASAWA HIROHARU
IPC: B41J2/185
Filed: 1989-03-13
Abstract: PURPOSE:To externally discharge ink in a nozzle at the time of reuse even if bubbles are generated to cause an improper discharge, and to simply eliminate the improper discharge by providing sucking means for sucking ink from a discharge port through a cap. CONSTITUTION:If the improper discharge of ink occurs due to a cause such as backward movement of a meniscus of the surface of the ink, generation of bubbles in a nozzle 3, a resilient cap 9 at the end of a cap slide 4 is brought into pressure contact with a recording head 1, and a lever 5 is slid between a cap securing plate 12 and the slide 4 in this state to be pressed down, thereby lowering a piston 26. Since a space 36 formed between the large-diameter part 27 of the piston 26 and the upper end of a pump body 20 becomes negative pressure by the expansion of its volume, the interior of a passage connected to the space 36 also becomes negative pressure. Since a tank for supplying the ink to the head 1 is always opened with the atmosphere, the ink in the nozzle 3 is externally discharged by means of the pressure difference before and after the nozzle 3.

Title: Thermal printer
Inventor: MATSUMOTO TOMOO
IPC: B41J25/312
Filed: 1987-03-18
Abstract: PURPOSE:To obtain a thermal printer wherein only small pressure is applied to a platen from a thermal head in a stop state to avoid the deformation of the platen and a pressure contact force applying/releasing mechanism or a detection sensor for detecting the presence of pressure contact force is unnecessary, by arranging the rotary shaft of the support of the thermal head to a lower part on a printing paper supply side or to an upper part on a printing paper feed-out side with respect to the circumferential tangential line of the platen at the contact point of the head. CONSTITUTION:A thermal head 1 is supported by a support 2 while the support 2 is made rotatable around a rotary shaft 3. A platen 4 composed of a rubber roller is arranged under the thermal head 1 to be rotated in the direction shown by an arrow A to feed the printing paper 5 fed between the platen 4 and the thermal head 1. Herein, the rotary shaft 3 is present at a part below the tangential line C at the thermal head contact point B of the circumference of the platen 4 on a printing paper supply side and an angle theta is formed by the tangential line C and the straight line D connecting the thermal head contact point B and the rotary shaft 3. By this constitution, sufficient pressure contact force is obtained during printing driving in spite of pressing force not deforming the platen at a non-printing stop time, and thereby a pressure applying/releasing mechanism or the detection of the presence of pressure can be omitted.

Title: Control device for thread
Inventor: ERITSUHI UEIDOMAN
IPC: B65H59/22
Filed: 1993-02-25
Abstract: PURPOSE: To provide a thread braking device capable of exhibiting less danger of damage to a thread and preventing the thread from being contaminated. CONSTITUTION: A thread breaking device includes a pair of braking members 6, 6', which are arranged symmetrically with respect to a thread running path. The braking members 6, 6' respectively have spring members 7, 7'. Between these spring members 6, 6', a line-shaped and vertically-arranged braking zone is defined for a thread 18. For effecting a braking action, the spring members 7, 7' are pivoted by control arms 8, 8' toward the thread running path. Due to this movement of the spring members 7, 7' as well as due to the vertical arrangement thereof, deposition of contaminations in the braking zone is avoided. The elasticity of the spring members reduces danger of damage to the thread in the presence of thickened thread sections.

Title: Lighting method and lighting system
Inventor: OTAKE SHIRO
IPC: H05B37/02
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To increase brightness produced by optical radiation, without increasing the quantity of optical radiation by presenting light whose intensity varies by specific time-dependent average illuminance and frequency from before a specific time of the time letting a seeing object make visible. SOLUTION: A bright lighting environment can be obtained by imparting light varying intensity with time as prior adaptation light, until immediately before making a seeing object visible. The intensity level of the prior adaptation light is made 0.01-1,000 lux, and the frequency is set to 0.2-10 Hz. After the prior adaptation light is switched to illumination light for visibility, adaptation to the illumination light for visibility proceeds. Effect of a low adaptation level produced by the prior adaptation light is kept for about five seconds, but after five second is passed, effect is decreased. Frequency of time-dependent variation of intensity in the prior adaptation light can resolve monotony caused by variation of a single frequency by mixing the variation of different frequency or time-dependent variation of the frequency.
