Title: Cooking sheet and cooking method
Inventor: TANAKA NORIYUKI
IPC: C01B31/04
Filed: 1993-07-16
Abstract: PURPOSE:To shorten the cooking time and to uniformly transfer heat to an object to be cooked, by using a graphite sheet as a cooking sheet. CONSTITUTION:An expanded graphite sheet formed of expanded graphite which is obtained by expanding a graphite material with a high multiplying factor and then by pressing the same which is therefore reduced into a sheet-like shape, is used as a cooking graphite sheet. The graphite sheet preferably has a thickness of 0.2 to 1.0mm. Further, if the bulk density of the graphite sheet exceeds 15g/cm<3>, the flexibility of the graphite sheet decreases so that the graphite sheet can hardly be shaped. Further, the bulk density is less that 0.5g/cm<3>, the thermal conductivity is low, and the strength thereof is insufficient so that the handling thereof becomes inconvenient. If the graphite sheet is shaped so as to surround an object to be cooked, infrared radiation and far infrared radiation are emitted from the surrounding around the object to be cooked, and accordingly, the object to be cooked can be more uniformly heated. For example, if a graphite sheet having beforehand shaped into a cylindrical shape is manufactured, the graphite sheet is shaped into a cylindrical shape, or the graphite sheet is bent and folded with a curvature so as to surround the object to be cooked, less vertically different browning occurs.

Title: Heat exchanger
Inventor: ADACHI MASAAKI
IPC: F25B39/00
Filed: 1982-12-21
Abstract: PURPOSE:To raise the heat conductivity of a heat exchanger as well as to lower the pressure loss of the heat exchanger by a method in which flow paths for two fluids are formed, a vapor-liquid two-phase fluid is passed through one of the flow paths, and the side of the vapor-liquid two-phase fluid is made up of a heating fin having at least two kinds of opening ratios in such a way as to obtain wide and dense heating surfaces. CONSTITUTION:A low-temperature liquid refrigerant flows into an inlet 8, and passes through many flow holes 5 provided in the inside heating fin 4. On the other hand, water flows into an inlet 10 and heat-exchanged with the wall faces as heating faces of the heating cylinder 1 and inside and outside heating fins 4 and 6 while flowing in many flow holes 7 provided in the outside heating fin 6. The refrigerant is vaporized, and the water is cooled to become cold water, and they are each discharged from outlets 9 and 11. Since the inside and outside heating fins 4 and 6 are closely attached to the flow paths of water and refrigerant, the heating surfaces become highly densed and widened. Also, since the opening ratio of the flow hole 5 of the inside heating fin 4 on the refrigerant side is made larger toward the direction of advancing the vaporization of the refrigerant or as a high dryness region is reached, the sectional area of the flow path of refrigerant is increased, and as the flow rate is lessened, the pressure loss can be reduced.

Title: Gate drive circuit in power converter
Inventor: TAKIZAWA AKITAKE
IPC: H02M1/08
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To make a reduction in a noise compatible with a reduction in a turning-on loss, by a method wherein a gate drive circuit at a switching device detects a value corresponding to the second-order differential of a current flowing to the switching device, and a drive means is operated when its detection output becomes a prescribed value or higher or lower. SOLUTION: An output signal in which a signal 3 having a value corresponding to the second-order differential of a current flowing to an insulated-gate bipolar transistor (IGBT) and a command signal (d<1> i/dt<2> ) 4 used to change over a gate resistance value are compared by a comparator 5 is inputted to a gate drive circuit at an FET 1. Then, on the basis of a compared output signal, the FET 1 is turned off only during a period in which the value corresponding to the second-order differential of the current flowing to the IGBT becomes a certain threshold value (d<2> i/dt<2> *) or lower. As a result, a reduction in a noise can be made compatible with a reduction in a turning-off noise.
