Title: D/a converting circuit
Inventor: ZAKOUJI MITSUYUKI
IPC: H03M1/82
Filed: 1989-07-28
Abstract: PURPOSE:To widely reduce the amount of data required for the output of waveforms and to obtain the desired waveform while preventing the reduction of system performance by successively reading out a target voltage and voltage change amount and executing D/A conversion while controlling the count value of a counter. CONSTITUTION:A frequency divider 10 divides the frequency of a reference clock with a frequency dividing ratio corresponding to the voltage change amount out of a pair of data read out from a data holding means 7 which holds the plural pairs of data concerning respective bending points. A digital comparator 11 compares the size of a count converting value for the voltage of the bending point out of a pair of the data read out from the data holding means 7, with the size of the real count value for an up/down counter 12 to define a clock, which frequency is divided by the frequency divider 10, as an operating clock. When the count value of the counter 12 is smaller than the count converting value, up-count is instructed to the counter 12 and when the count value is larger, down-count is instructed. A D/A converter 14 converts the real count value of the counter 12 to an analog voltage.

Title: Absorbing method in waste gas desulfurizing equipment
Inventor: OGURI HARUO
IPC: B01D53/77
Filed: 1981-12-15
Abstract: PURPOSE:To maintain a high desulfurization ratio and to eliminate an oxidizing tower as well as to avoid a clogging obstacle with the formation of gypsum, by introduing a liquid in which air is preliminarily dissolved under pressure into a liquid accumulation tank. CONSTITUTION:The part of a recirculated absorbing liquid is introduced into a pressurizing tank 20 from a branched return passage 19 and the absorbing liquid 14a of which the air content is increased by dissolving air 1 under pressure is returned into a liquid accumulation tank 15 from a relatively high pressure position through a sparger 23. Air dissolved in the absorbing liquid is formed into air bubbles with the releasing of pressure and raised while the absorbing liquid 14 is subjected to aeration treatment. Because the formed gypsum 24 is sent to a filter machine to be recovered and the solubility of CaCO3 is lowered but, by the aeration treatment, the solubility and the dissolving speed of CaCO3 are enhanced. In addition, air bubbles are not generated in the absorbing liquid with high air content directly before discharged from the sparger 23 because of high pressure and the sparger 23 is not clogged by the precipitation and  the adhesion of gypsum.

Title: Electronic parts
Inventor: ONO HIDEYO
IPC: H04W88/02
Filed: 1990-07-27
Abstract: PURPOSE:To make the electronic parts light in weight and low-priced by letting jamming radio waves, which come from a signal line, flow through a capacitor to a ground side and letting unnecessary radio waves, which are radiated from the electronic parts, flow to the ground side after catching them. CONSTITUTION:Jamming radio waves coming from an antenna, etc., to an IC 43 are reflected or caught by a thin copper piece 431. The caught radio waves are guided to a ground face by soft copper wires 433 and 434. In this case, the level of the unnecessary wave generated by mixing is extremely low, and since this unnecessary wave is caught by the thin copper piece 431 and guided to the ground face although it is radiated from the IC 43, the unnecessary wave does not arrive at the antenna 3. Further, jamming waves made incident to the circuit pattern of a circuit board 49 are bypassed by a capacitor 437 loaded on the IC 43 before going into the IC 43. Thus, the electronic parts can be made light in weight and low-priced.

Abstract: PURPOSE:To form toner images like sharp image patterns easily by using the developer consisting of at least two components of the 1st particles having conductivity and magnetism and having a visual color and the 2nd particles having a color differing from the same. CONSTITUTION:DC bias is applied between a sleeve 5 and a transparent conductive substrate 12 of a photoreceptor by using the developer mixed with the 1st particles 6a of a certain color and the 2nd particles 6b which are smaller in grain sizes than said particles, have about the same conductivity and magnetism as those of the 1st particles and have a different color. Picture light is exposed to the position where the developer and the photoreceptor contact. In the non- picture parts, that is, in the dark parts D, the electric field is weak and if the 2nd particles 6b stick on the photoreceptor, the 1st particles 6a hardly stick thereon, but in the bright parts L, negative charge is generated on the surface of the photoreceptor to obtain the strong electric field and the 1st particles 6a having relatively large grain sizes stick sufficiently on said parts as well. The images formed in such a way are substituted by the another color in the fogged parts of the base to obtain the sharp pictures.
