Title: Joint cutting method of concrete face
Inventor: HACHITANI KAZUAKI
IPC: E04G21/02
Filed: 1993-09-21
Abstract: PURPOSE:To prevent a joint groove from breaking, by cutting a joint so as to form a joint groove before drying the superficial part of surface-finished concrete and covering the edge of joint groove and inserting a joint material to engage it with the joint groove and forming cracks in the joint groove. CONSTITUTION:A joint groove 2 is formed on the surface of placed concrete by use of a light joint cutter obtainable in the market, before the surface of placed concrete dries. Next, a joint material 3 is inserted and stuck into the joint groove 2 before the surface of concrete dries. Next, the placed concrete is cured and dried. In this way, the edge of joint groove 2 is not broken due to external causes. And cracks 7 formed due to the initial contraction and dried contraction of concrete can be concentrated in the joint groove 2.

Title: Oxygen sensor
Inventor: KUROSAWA HIDEYUKI
IPC: G01N27/00
Filed: 1987-09-19
Abstract: PURPOSE:To obtain a stable sensor which is simple and whose power consumption is small by constituting a zirconia solid-state electrolyte substrate of a porous substrate, and using it as a diffusion controlled speed means. CONSTITUTION:On both faces of a zirconia solid-state electrolyte substrate 21, porous electrode layers 22, 23 are formed, and the electrode 23 is isolated and closed up hermetically from an external atmosphere by a spacer 25 and a sealing plate 26. In this state, first of all, the substrate 1 is heated, and subsequently, between the electrodes 22, 23, a DC constant-voltage is applied. As a result, oxygen being at the electrode 23 side is ionized, moves in the substrate 21, and an oxygen ion which has reached the electrode 22 is oxidized and blown off as gas oxide. Therefore, since oxygen partial pressure of the electrode 23 side drops, oxygen flows in from an external atmosphere through a pore of the substrate 21. In this case, since the substrate 21 functions as a diffusion controlled speed layer, oxygen diffused to the electrode 23 side is brought to controlled speed, and the oxygen partial pressure of the electrode 23 side is balanced to the oxygen partial pressure of an external atmosphere with some difference. In this case, between the electrodes 22, 23, a threshold current being in a steady state which does not depend on the applied voltage flows, and by measuring this current value, oxygen concentration of the external atmosphere can be determined.

Title: Method for continuously casting molten steel
Inventor: OSAKI MASAHIRO
IPC: B22D11/10
Filed: 1994-09-30
Abstract: PURPOSE: To reduce the surface defect on a steel product by arranging a nozzle for discharging molten steel only in one direction on the opposite sides in a mold and pouring the molten steel from the nozzle along the inner wall of the mold so that discharged flows do not mutually interfere. CONSTITUTION: The molten steel is discharged from the discharging holes 5, 5a of immersion nozzles 4, 4a. The discharged flows forms circular flows in the horizontal direction in the mold 3. Since the residence zone for the molten steel 6 does not exist in the mold 3, and the ascending flow does not form, the entrapment of power, etc., on the molten steel surface is not occurred. Since the descending flow does not form, the inclusion in the steel is not transferred to the zone high in viscosity near the solidified layer. The molten steel is allowed to slowly flow on the surface of the solidified layer and this flow removes the inclusion, gas bubble, etc., stuck on the surface of the solidified layer. The occurrence of breakout is prevented.

Filed: 1983-12-15
Abstract: PURPOSE:To enhance S/N of a color difference signal and reproduced picture quality by transmitting signals so that a color difference signal at an output terminal of a DA convertor will change in a full-range from a pedistal level to a white peak level by digital processing. CONSTITUTION:A digital line sequential color difference signal, which was subjected to time base compression from an RAM16, is supplied to a multiplier circuit 17. Said circuit 17 multiplies said signal by such a coefficient that the maximum amplitude of a DA converted signal will be approximately equal to that ranging from a pedistal level of a luminance signal to a white peak level, and outputs a digital signal with the same seven bits as the number of quantized bits of a digital luminance signal. This means that since the multiplier circuit 17 transmits the line sequential color difference signal which has been DA-converted, utilizing fully said level range, an multiplying coefficient is selected so that level information of said signal will be about 7.5 times.
