Filed: 1989-12-05
Abstract: PURPOSE:To provide a cooking pot capable of roasting, steaming and boiling without scorching and smoking, by a method wherein, in the inside of a ceramic vessel with a bottom, a ceramic middle-vessel with a bottom, of which the outer diameter is slightly smaller than the inner diameter of the vessel, is placed, and a ceramic lid having an engagement part near the periphery thereof is placed on the opening part of the top of the vessel. CONSTITUTION:When a ceramic vessel 1 is placed on a heat source 30 such as a gas range or an electric heater and a lid 20 is placed so that a recess 22 thereof is at the top thereof, the heat source heats the lid 20 through the air of the inside 9 of the vessel 1, and hence pieces of meat A are placed on the lid 20 and can be quickly roasted. The heated air enters the inside 9 of the vessel through through-holes 3 on a bottom 2 of the vessel 1, and heats a middle-vessel 10, and then rises through cut parts 12 among leg parts 11 for the middle-vessel 10 as shown with arrow marks. After that, the heated air is exhausted to the outside through air holes 5 on a wall 4 of the vessel and air-exhausting parts 7 formed at cut parts of a top 6 of the vessel, and hence the heated air is effectively circulated in the vessel 1 by convection and can equally heat the lid 20. For that reason, pieces of the meat A or the like can be roasted without scorching and smoking, and the fat distilled from pieces of the meat A flows down through grooves 24 on the lid 20 and collects in a groove 25 for the fat, around the led 20. As the result of it, pieces of the meat A are not sticky and can be deliciously roasted.

Title: Fabrication of semiconductor device
Inventor: KADOMURA SHINGO
IPC: H01L21/28
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To remove natural oxide efficiently while reducing damage to a substrate. SOLUTION: Natural oxide is removed from the surface of the layer of silicon based material using a pulse time modulation plasma of hydrogen based gas. Since the effective electron temperature is lower in the pulse time modulation plasma as compared with a continuous discharge plasma, generation of high energy hydrogen based active species is suppressed. Furthermore, the sheath voltage decreases and thereby the collision energy of charged particle decreases. Especially, when the effective electron temperature is selected lower than the interatomic bonding energy of Si-Si bond, possibility of destruction of a crystal lattice in a single crystal Si substrate is substantially zero. According to the method, natural oxide on the bottom face of the contact hole or on the surface of source/drain region 16 in the salicide process can be removed well.

Title: Condenser discharge type ignition device for internal combustion engine
Inventor: SASAKI KOJI
IPC: F02P3/08
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To improve starting properties of an engine by increasing spark energy when a temperature of the engine is low. SOLUTION: A voltage applied from an exciter coil 2 to an ignition circuit 1 is controlled by conducting a thyristor T when a voltage detection signal Vs obtained by dividing an output voltage of an exciter coil 2 by a resistor divider of an exciter voltage detecting part 401 reaches a set value to thereby short circuit the exciter coil 2. A temperature sensitive resistive element Rt1 having a negative temperature coefficient is connected to both ends of a resister R2 of the resistor divider constituting the exciter voltage detection part 401. When a temperature of an engine is low, a voltage dividing ratio of the resistor divider is reduced to thereby set a limiting value of the output voltage of the exciter coil 2 in low temperature high. Accordingly, spark energy is increased.
