Title: Method for solidifying granular steel-making slag
Inventor: NAKAGAWA MAKIKO
IPC: B09B3/00
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To improve the solidification strength of granular steel-making slag by a method in which, in an apparatus in which the slag is contact-reacted with gas containing carbon dioxide or carbonic acid water in a highly wet atmosphere to be carbonated, the slag after being washed with an acid is carbonated. SOLUTION: Steel-making slag contains CaO and Al2O3 as main components, and CaO reacts with water to cause expansion destruction. To make a solid substance applicable to a practical use as a roadbed material and a building/civil engineering material, it is necessary to convert it in advance into a substance free from the expansion destruction. Namely, the granular slag containing at least 50 wt. % of particles 5 mm or below in particle size is contact-reacted with gas containing carbon dioxide or carbonic acid water in a highly wet atmosphere to be carbonated. In this process, the slag, after being washed with an acid, is carbonated. Preferably, the slag after the carbonation is kept in a water-containing state or heated in high pressure steam.

Title: Induction heating roller device
Inventor: KITANO YOSHIO
IPC: H05B6/14
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To uniformly cool the surface of a roller with a simple structure without using any large-sized cooling pipe by using an induction heating roller also as a cooling roller to efficiently generate heat, taking the heat of a gas phase heating medium by the heat of a load by use of a coolant in cooling, and discharging it. SOLUTION: A plurality of jacket chambers 8 is provided on the thick part of a roller along the circumference so as to extend in the axial center direction, and a two-phase heating medium 9 of liquid and gas sealed each in the inner part thereof. When the roller is induction heated, the liquid phase heating medium 9 is evaporated by the contact with the inner circumference of the roller, and then converted to a liquid phase by the contact with the low-temperature circumferential wall to release the latent heat, which heats the low-temperature circumferential wall of the roller, whereby the surface temperature distribution of the roller is uniformed.  When the load temperature is higher than the temperature of the roller in the use of the roller for cooling, the roller locally becomes a high temperature, the liquid phase heating medium 9 touched to it is evaporated to take the latent heat, and then liquefied by the contact with the low-temperature part of the roller to impart the latent heat thereto, whereby the surface temperature distribution of the roller is uniformed.

Title: Controller for electronic device
Inventor: IBA AKIO
IPC: G06F9/32
Filed: 1982-09-24
Abstract: PURPOSE:To change the next address to be executed with a signal bed from an external circuit, by using an adder circuit which gives an input to an address terminal of an ROM and a selecting circuit which selects the 2nd input or the carry input of the adder circuit with an external input signal. CONSTITUTION:The signals supplied to ekip terminals SKT2 and SKT3 are fed to an AND22 and AND23 respectively. In this case, however, the address value of a half adder HA1 which is previously supplied from an ROM through the latch circuit group varies since a skip control signal S1is fed to AND22 and 23 respectively from a control signal generating part CONT. At the same time, skip terminals SKT1-SKT3 deliver the input to AND19-AND21, and skip control signals S2-S4 are fed to the 2nd input and controlled through an OR2 so as to give +1 to the address to be executed next. In such a way, a program memory is saved and at the same time the using efficiency is improved for a register.

Title: Branching filter circuit
Inventor: ITANAMI TAKAO
IPC: H01P1/213
Filed: 1984-08-08
Abstract: PURPOSE:To obtain a branching filter circuit offering an excellent characteristic over a wide frequency range with small size and light weight by using a ridge waveguide for a waveguide having a low cut-off frequency and using a waveguide having a ridge whose height is changed gradually as a connecting waveguide. CONSTITUTION:The ridge waveguide 1a has a ridge for both wide faces, its cut- off frequency is lower than a low frequency fL, and the connecting waveguide 3a has a ridge 8 whose height is changed gradually at both wide faces. A wave of a high frequency fH is propagated in the connecting waveguide 3a without being cut off and a wave of a low frequency fL is cut off on the way of the connecting waveguide 3a and reflected completely. Since one sub waveguide 6 is enough in the branching filter circuit of such constitution above, the entire shape is small in size and light in weight. Further, the cut-off frequency of the TE20 mode in the connecting waveguide 3a is high by the effect of the ridge 8 provided to the connecting waveguide 3a. Thus, no characteristic deterioration by the TE20 mode is caused.

Filed: 1989-06-28
Abstract: PURPOSE:To prevent the diffusion of impurity so as to obtain an ohmic electrode extremely high in wire bonding rate by a method wherein an Mo layer is interposed between a contact layer and a pad layer. CONSTITUTION:The ohmic electrode of an N-type or a P-type AlGaAs 1 of a light emitting element is formed of a contact layer 2, an Mo layer 3, and a pad layer 4, where the layer 3 is interposed between the layers 2 and 4. The thickness of the Mo layer 3 is 50-1000Angstrom , and it is adequate that the composition of the AlGaAs 1 concerned is so set as to satisfy an inequality, 0.2<x<0.8, when the composition is represented by a formula, AlxGa1-xAs. For instance, AuGe500Angstrom /Mo500Angstrom /Au1500Angstrom  is evaporated on an N-type AlGaAs, which is alloyed at a temperature of 500 deg.C, and then an LED is formed. By this setup, impurity is prevented from diffusing to the surface of an electrode from an AlGaAs side, and an Mo layer itself never diffuses to the surface of a pad layer, so that the surface of the electrode is excellent in cleanness and becomes excellent in wire bonding property.
