Title: Continuous casting mold powder for extra-low carbon steel
Inventor: WASHIO MASARU
IPC: B22D11/108
Filed: 1987-09-18
Abstract: PURPOSE:To decrease the surface defects of extra-low carbon steel occurring in mold powder by adding Na2O;B2O3 of limited components to the mold powder for continuous casting of steels which consists of SiO2;CaO;Al2O3 limited in components by weight ratios. CONSTITUTION:<=1.0% Na2O and 5-20% B2O3 are incorporated into the mold powder for continuous casting of extra-low carbon steels which contains, by weight, 30-60% SiO2, 20-50% CaO and 1-15% Al2O3. The reasons for limiting the SiO2;CaO;Al2O3 are as follows: While the SiO2 has an effect of lowering the softening point, the effect is insufficient at <30wt.% and the viscosity increases in excess of 60wt.%. The powder is crystallized if the CaO is excessive ly added to the powder and, therefore, the content thereof is limited to the above-mentioned range. The content of the Al2O3 is automatically determined to the above-mentioned range when the content of the SiO2;CaO is determined. The effect of lowering the rate of crystallization is obtainable by limiting the content of the Na2O;B2O3.

IPC: F28F1/40
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To improve the condensing performance as well as the evaporating performance of refrigerant. SOLUTION: A refrigerant 4, utilized for a refrigerating cycle, flows under the condition of gas and liquid two-phase while a heat transfer tube with internal surface grooves is provided with a plurality of spiral inner surface fins 2, condensing or evaporating the refrigerant 4, and internal surface grooves 3, provided between respective internal surface fins 2. Respective internal surface grooves 3a, 3b are constituted so as to have at least two kinds of groove widths of a groove width W1, facilitating the condensing of the refrigerant 4, and a groove width W2, facilitating the evaporation of the same. The groove width of the internal grooves 3a, 3b is changed so as to be two kinds of more of a large groove width W1 and a small groove width W2 while the large groove width W1 and the small groove width W2 are arranged alternately.  Accordingly, liquid is hardly reserved in the large groove width W1 and the condensing performance of the liquid is improved while the liquid is readily reserved in the small groove width W2 and the evaporating performance of the liquid is improved.

Title: Stepping control for time recorder
Inventor: KOGO TAKASHI
IPC: G07C1/00
Filed: 1987-09-18
Abstract: PURPOSE: To eliminate a step position shift and give a print always at a correct position by temporarily interrupting operation when a time card is inserted halfway in stepping-up operation, and performing the remaining stepping-up operation after the card is drawn out. CONSTITUTION: A step-up signal S4 is supplied five times from a control circuit 5 to a step-up solenoid driving circuit 55 for five-stage stepping-up operation, and when two pulses P1 are outputted to a step-up solenoid 56, the time card is inserted and a card detection switch 53 operates; if a pulse P2 is generated, the circuit 55 temporarily stops supplying the pulse P1. Then the three remaining pulses P1 are supplied a T time later after printing operation ends, the time card is drawn out, and the detection switch 53 turns off. Stepping-up operation is performed with the spring force charged in a return spring with the previous pulse P1 before the T time, so no step position shift is caused. Therefore, desired stepping-up operation is performed correctly with the leaving two pulses P1 and remaining pulse P1.

Filed: 1984-11-08
Abstract: PURPOSE:To obtain a recording liquid for ink jet system or writing utensils, free from nozzle clogging, development of sediments and foreign substance settling on heating head, by regulating to a level below specified value the content of the Mg as an impurity present in an ink composition containing water-soluble dye. CONSTITUTION:The objective recording liquid, being a liquid composition containing a water-soluble dye, can be obtained by regulating the content of the Mg present in said composition to a level <=4ppm. This recording liquid is used, for example, in ink jet recording system operating by applying thermal energy. For said regulation, one of the processes is as follows: sodium sulfate is added to an aqueous dye solution to subject the dye to salting-out. The resulting precipitate deposited is collected by filtration, being washed with aq. Na2SO4 solution and dried. The solid thus obtained is dissolved in a water- soluble organic solvent followed by filtration. The resultant filtrate is incorporated with water followed by passing the liquid through cation exchange resin layer then pH adjusting. This filtrate is left at rest for 7-10 days followed by filtration.

Title: Imaging device
Inventor: TAKEDA FUCHIO
IPC: G03G15/06
Filed: 1986-10-03
Abstract: PURPOSE:To prevent the area of a photosensitive body from being developed in flat black during the period from the start of movement of a photosensitive body due to imaging up to the arrival of the area at a developing area through an imaging area by arranging a potential shifting voltage generating part for setting up the potential of a base part electric conductor of the photosensitive body to a value different from that of an earth part of an imaging device between a base part electric conductor and a earth part. CONSTITUTION:The potential shifting voltage generating part 20 is provided between the electric conductive base part conductor 11 of the photosensitive body 1 and the earth of the whole device and a developing bias power supply 13 is formed by a simple constitution having only an ON/OFF switching circuit. The voltage generating part 20 shifts high voltage source systems 10, 15 and the photosensitive body 1 from the earth part of the device body by the voltage generated from itself. Since the developing bias is simple kept at OFF during the period from the start of movement of the photosensitive body up to the arrival of an area A at the imaging area through the developing area, it is unnecessary to propose a bipolar switching circuit. The output value of the voltage generating part 20 may be set up to a value larger than a value setting up the quantity of toner sticking to the area A to zero.

Title: Optical axis detecting device
Inventor: KIDOKORO HITOSHI
IPC: G01C15/00
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To provide an optical axis detecting device for detecting deviation in an optical axis in a vertical direction even at the time of using a radar head for scanning laser beams in a horizontal direction. SOLUTION: A reflector 201 arranged in a vertical direction and a reflector 202 arranged in an oblique direction are irradiated by a laser device, and the position with strong reflection strength from the vertical reflector is defined as a central position. A distance between the positions of the both edges with weak reflection strength from the oblique reflector and the center is calculated so that the angle of irradiation in the vertical direction can be detected. For example, when the angle of irradiation of a laser radar is directed more upward than a horizontal direction, the range of irradiation on a target board is biased upward, and a difference(x1>x2) is generated in the distance from the center.  The value of the distance is made correspond to a shearing angle Ψ (angle of irradiation) from the horizontal face so that a shearing angle Ψ in the vertical direction can be calculated by calculating the value.
