Title: Idling speed control device for engine
Inventor: YAMAGATA HIROTO
IPC: F02D41/16
Filed: 1986-04-26
Abstract: PURPOSE:To enable a normal regulation of the idling engine speed properly by causing a learning value stored in a learning value calculating and storing means to be reset in relation to the operation of a feedback control inhibiting means which is caused by an idling speed regulating means. CONSTITUTION:When a feedback control inhibiting means 6 is not put in operation, a feedback control, which is performed by a feedback controlling means 5 so that an actual idling engine speed is caused to converge on a target idling engine speed, is made in accordance with a learning value which is updated and stored in a learning value calculating and storing means 4. On the other hand, when the feedback control inhibiting means 6 is put in operation by an idling ending speed regulating means 7, such control is made by the idling engine speed regulating means 7 so that an actual idling engine speed is caused to agree with a target idling engine speed. Hereupon, a learning value is reset by a learning value resetting means 8. Thereby, an error in the learning value is prevented from exerting an adverse effect upon the regulation of the idling engine speed.

Title: Variable slit heat exchanger
Inventor: MUKODA HIDEAKI
IPC: F28F1/32
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To achieve a higher energy efficiency of equipment by further lowering a low pressure loss with a higher heat transfer efficiency of a heat exchanger. SOLUTION: Slit fins 5a, 5b, 5c and 5d are formed in a heat exchanger fin by being cut and erected sequentially to the downstream side from the upstream side of air sucked. The slit fin 5a is formed with the height a1 and width b1 in dimension, the slit fin 5b with the height a2 and the width b2, the slit fin 5c with the height a3 and the width b3 and the slit fin 5d with the height a4 and the width b4. There is little air on the upstream side of the air sucked making a kind of approach section. Air high in speed passes through the surface and the rear of the slit fin 5a to accomplish heat exchange action sufficiently though the height a1 and the width b1 are small and with a small air resistance, it also acts on the slit fin 5b at the next stage without a substantial drop in the air speed.  The slit fin 5b also accomplishes a sufficient heat exchange action as the height a2 and the width b2 thereof are larger than those of the slit fin 5a. Likewise, the slit fins 5c and 5d can exert such a heat exchange action sequentially.

Title: Facsimile equipment
Inventor: SHIME MASARU
IPC: H04N1/00
Filed: 1981-06-26
Abstract: PURPOSE:To prevent a mistake by discriminating the top from the reverse of a transmission original. CONSTITUTION:When the front edge of an original is detected, the counters of a transmission line counting part 1 and an all-white line counting part 2 are both cleared. Every time one line is read, a line synchronizing signal is inputted to a reverse-side detection part, and the transmission line counting part 1 adds 1 to the contents of the counter by the input signal. The all-white line counting part 2, when this line synchronizing signal and an all-white signal inputted according to a one-line all-white state are both on, adds 1 to the contents of the counter. This operation is repeated until one original ends. After one-sheet transmission, a line-number comparison part 3 operates to the ratio of the number of all-white lines to that of transmission lines, and when the ratio is greater than a certain reference value (e.g. 0.95), the reverse side is judged to output a signal to an abnormality display part 4, thus letting a person in charge of transmission know the abnormality through display.

Title: Ic-mounted printing head
Inventor: KOMATSU KATSUAKI
IPC: B41J2/345
Filed: 1986-04-30
Abstract: PURPOSE:To reduce the height of a sealing member which covers the surface of an IC for miniaturization by providing the IC in a recess on the surface of a substrate concerning a printing head having a dot printing part and the IC for driving said dot printing part on a substrate. CONSTITUTION:A recess is formed on a substrate 1 and an IC 7 is adhered in the recess using an adhesive of epoxy resin, etc. For this reason, the height of a sealing member 10 is reduced, so that a recording material 12 does not contact the sealing member 10, if the distance between a dot printing part H and an installation position of the IC 7 were shortened. Accordingly cost can be cut through miniaturization. A glazed layer 2 is formed on the substrate 1 by making pulverized glass adhere using silk screen printing and baking it 700-800 deg.C. Consequently it is easy to obviate the need for the glazed layer 2 in the recess of the substrate 1. Further the depth of the recess should preferably be almost the same as that of the IC 7.

Abstract: PURPOSE: To prevent the occurrence of the defect of a strip product to be produced by using ordinary refractories, such as alumina graphite, by setting preheated metal flow limiting refractory members to a pair of parallel casting rolls and executing pouring in the nip between a pair of the parallel casting rolls. CONSTITUTION: Molten metal is supplied via a tundish 18 and a delivery nozzle 19 to a pair of the parallel casting rolls 16 and the parallel casting rolls 16 are cooled, by which a solidified shell is produced on the parallel casting roll surfaces and is passed through the nip of the parallel casting rolls, by which casting is executed. The tundish 18, the delivery nozzle 19 and side closure plates 56 to form the pool of the molten metal on the parallel casting rolls 16 are separately preheated to a service temperature and are rapidly assembled into an operation assembly, by which the casting is started before the nonuniform or local cooling occurs in the preheated component parts.  The delivery nozzle 19 and the side closure plates 56 are subjected to oxidation retarding coatings, such as ceramic glaze, or their preheating is executed in an inert atmosphere in order to prevent the deterioration of the refractories or the occurrence of irregularities of the molten metal flow by oxidation in preheating.

IPC: B23K35/30
Filed: 1980-07-17
Abstract: PURPOSE: To enable perfect welding to be performed even in spheroidal graphite casting by making the cooling rate of the weld zone in welding process less than predetermined value and performing root-pass welding through plasma keyhole welding then performing the 2nd-pass welding by using the spheroidal graphite cast iron made welding material comprising the specific components.  
     CONSTITUTION: Root-pass welding is performed through plasma keyhole welding by determining material temperature in such a manner that the maximum cooling rate of the weld zone of spheroidal graphite cast iron material and near the same be- comes less than the upper threshold cooling rate of the continuous cooling transformation curve determined by the composition of this cast iron material, that is, while preventing the cracking of the weld zone. Thence, the 2nd-pass welding by gas welding etc. is performed by using eutectic welding material in the recesses produced in the surface of the weld zone by this root-pass welding. An electrode made of spheroidal graphite cast iron comprising 2W4wt% C, 1.5W5wt% Si, 0.02W 0.20wt% Ca or/and Mg and Fe for the remainder is used for this eutectic welding material.

Title: Electrifying mechanism for electrophotographic printer
Inventor: WATANABE AKIO
IPC: G03G15/02
Filed: 1987-04-21
Abstract: PURPOSE:To prevent a variance of the surface potential of a photosensitive drum by varying a current flowing through a grid of an electrifier, in the first rotation and the second rotation and thereafter, based on an output of a rotation detecting sensor of the photosensitive drum. CONSTITUTION:A timer 6 outputs a 'Low' level only when an OPC drum (photosensitive drum) 5 makes one rotation, by which a transistor 8 becomes ON through an inverter 7, and a resistance 9 is short-circuited. In this case, a current which has flowed out of a discharge electrode 3a flows to the OPC drum 5 and an electrically connected grid 3c, and a reflecting plate 3b, but the sum of the currents flowing to the grid 3c and the reflecting plate 3b is limited by a varistor 10 and a resistance 11 due to a short circuit of the resistance 9, and the remainder flows to the OPC drum 5. When the timer 6 becomes a 'High' level, the transistor 8 becomes OFF, the sum of the currents flowing to the grid 3c and the reflecting plate 3b is limited by a combined resistance of the varistor 10, the resistance 11 and the resistance 9, and the remainder flows to the OPC drum 5. In such a way, the OPC drum is electrified a great deal in the first rotation and electrified a little in the second rotation and thereafter, by which a variance of the surface potential of the OPC drum can be reduced.
