Patent JP-H06146208-A (JP)
Title: Plate heater
Inventor: SUZUKI TETSUO
IPC: H05B3/20
Filed: 1992-11-02
Abstract: PURPOSE:To achieve efficient heating and reduce cost by accumulating honeycomb structures which store heat and have heat insulation effect on the face of heater like plate and imbedding them in the road in cold districts. CONSTITUTION:Dry mixing mortar is spread on the road ground, and a plate heater 100 and asphalt pavement are accumulated on it sequentially. When a heater 5 of the plate heater 100 is heated, heat is radiated from the top and bottom faces of the heater 5. Then, heat radiated on the top face side is stored in a honeycomb structure 1 on the upper side, and heat radiated on the lower side is insulated by a heat insulating material 3 and the structure 1. Accordingly, heat of the heater 5 scarcely escapes into the soil and is stored in the structure 1 to make the road surface warm. The structure 1 is formed in such a way that many holes 15 of roughly conical shape use a side wall 17 in common on the top and bottom faces of a plate made of synthetic resin, and has sufficient heat storage and heat insulation functions owing to air in the holes 15. Consequently, it is possible to utilize heat efficiently and assemble and construct it easily because its structure is simple and light-weight.

Title: Thermal head
Inventor: OKUHARA YASUFUMI
IPC: B41J2/345
Filed: 1987-12-14
Abstract: PURPOSE:To eliminate the irregularity of printing density, by providing a thermal element in the vicinity of a heat generating resistor. CONSTITUTION:When a signal is inputted to enable input 7, a monomultivibrator circuit 6 outputs the positive pulse proportional to the time constant determined by a substrate temp. detecting resistor 5 and a condenser 8. At this time, when printing data is H, a control signal becomes L and a current flows to a heat generating resistor 3. The current supply time of the heat generating resistor 3 is determined by the above mentioned time constant but, when the temp. of a thermal head substrate 1 is high, the time constant becomes short (because the substrate temp. detecting resistor 5 has a negative temp. coefficient) and, therefore, a current supply time becomes short. Contrarily, when the temp. of the thermal head substrate 1 is low, the time constant becomes large and the current supply time of the heat generating resistor 3 becomes long. As mentioned above, since the current supply time of the heat generating resistor 3 is changed corresponding to the change of the temp. of the thermal head substrate 1 and the temp. of the heat generating resistor after the supply of a current is kept constant regardless of the temp. of the substrate 1, printing generating no density irregularity can be performed.

IPC: G06F9/38
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To increase the arithmetic processing speed and to prevent the increase of the circuit scale. SOLUTION: A CPU 20 performs the 1st and 2nd instruction processes via a pipeline process. In the 1st instruction process, a computing element 23a performs an arithmetic process by means of the data given from a 1st bus 27. Then the arithmetic result data obtained from the element 23a are stored in a resister R2 of a register group 21 designated by a control part 35 via a 2nd bus 29. At the same time, a computing element 24a which performs the 2nd instruction process sometimes reads and fetches the arithmetic result data under storage as a computing subject. Under such conditions, a selector 30 outputs the arithmetic result data to the bus 27 from the bus 29. In other words, the arithmetic result data can be outputted to the bus 27 where both elements 23a and 24a can fetch the data by a single selector 30.

Abstract: PROBLEM TO BE SOLVED: To obtain a large-scale integrated circuit device that is more efficient, by calculating the delay time of a macro on the basis of delay characteristic data concerning a designed logic circuit, and logically simulating the designed logic circuit according to the found delay time. SOLUTION: When the macro is registered in a logic library, the macro is regarded as a macro core 35 and boundary cells 31 to 33 are regarded an input initial-stage cell and an output final-stage cell, thereby registering the added macro 34. Further, the boundary cells 31 to 33 are arranged nearby the input terminals MA and MB and output terminal MX of the new macro 34. Thus, the boundary cells are added nearby the input terminals MA and MB and output terminal MX and the macro 34 is registered. Consequently, the input terminals and boundary cells correspond to each other one to one firstly and then the delay time depending upon an input through rate can easily and accurately be calculated by making good use of characteristics or characteristic parameters of the boundary cells.

Abstract: PURPOSE:To obtain a heat-treating furnace capable of heat-treating uniformly materials to be heat-treated by forming a plurality of fine holes in a furnace body so that an atmospheric gas is blown in a direction reverse to the rotational direction of a case and downwardly into a heating chamber. CONSTITUTION:A furnace body 1 has fine holes 6 for blowing an atmospheric gas, which communicate the external side to each region 4, the fine holes being formed at four places at every region 4, respectively. Each region 4 in a heating chamber 2 is heated up to a predetermined temperature by a heater 5, and the atmospheric gas is blown into the region through the fine holes 6 of the furnace body 1 in a direction reverse to the rotational direction of a case and downwardly toward the heating chamber 2. Then, the cases 30 containing materials 8 to be heat-treated are conveyed successively through the upper opening of the furnace body 1 to be stacked on a rotary base 21. This rotary base 21 is lowered while being rotated and, when a second case 30a from the bottom comes to a predetermined position at the lower opening of the furnace body, the case is held by a holding jig 7. Thereafter, the rotary base 21 is stopped when its upper face is flushed with the upper face of a stand 12. As a result, it becomes possible to keep a heating temperature uniform at every portion of the materials to be heat-treated, and the materials can be heat-treated without irregularity.

Of the released rays, the rays of blue and green wavelengths are irradiated to respective liquid crystal display panels 8, 9 for blue and green by dichroic mirrors 3, 4 and a total reflection mirror 5. The other light source for a red wavelength is constituted by providing a lens system 13 on the optical path for irradiating the liquid crystal 10 for red with the light of this light source via the respective dichroic mirrors 3, 4 and the total reflection mirrors 6, 7. Namely, the distances from the light source 1 to the liquid crystal display panel 9 for blue are equal to each other but the distance from the light source 1 to the liquid crystal display panel 10 for the red is longer than the above-mentioned distance. The lens system 13 for correcting the illuminance distribution is, therefore, disposed on the optical path in which the rays of the red wavelength pass.
