Abstract: PURPOSE:To remove perfectly and easily irradiation defects without resulting in crystallization defects in their vicinities, by a process in which a silicon layer with irradiation defects is oxidized under a high pressure and a low temperature and is etched away with hydrofluoric acid, etc. CONSTITUTION:An oxidized film 2 with a predetermined film thickness is formed on a silicon substrate 1, a resist film 3 is deposited thereon, and then a window 4 is opened through a given region of the resist film 3. Using the resist film 3 as a mask, the oxidized film 2 directly underlying it is etched with hydrofluoric acid to form a window 5, the resist film 3 is removed, and the silicon substrate 1 is reactive-ion-etched using the oxidized film 2 having the window 5 formed as a mask to form a groove 6. This is placed in a quartz vessel 11 in a high pressure and low temperature oxidizing apparatus 19 to do oxidizing process. In this etching, the silicon layer with irradiation defects 7 caused in the groove is oxidized to form a oxidized layer 8 united with the oxidized film 2, and the oxidized layer 8 and the oxidized film 2 are removed with wet etching. The irradiation defects in a silicon layer can be removed perfectly and easily without resulting in crystallization defects in their vicinities.

IPC: F24C7/02
Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To prevent a failure of cooking by comparing an output of a weight sensor with a reference weight after a door is opened or closed, and rewriting the reference weight if a difference of them falls within a predetermined range. SOLUTION: When a material to be cooked is disposed in a cooling container, the container is disposed on a table base 17, a door 12 is closed and a starting operation of cooking is conducted, in the case of oven cooking, burnt hot air of a gas burner 5 is returned to a cooking chamber 3 by an operation of a circulating fan 7. When the cooking is finished, the door 12 is opened, the material is taken out, and the cooking is finished. Then, opening or closing state of the door 12 is detected. That is, after an operation of a leaf spring is stabilized when 3 sec is, for example, elapsed when the door 12 is closed, an output of a weight sensor 23 is compared with a reference weight.  If the output of the sensor 23 falls within a tolerance of a preset predetermined range of the reference weight, it is judged that notching is disposed on the base 17, and the output of the sensor 23 is rewritten as the reference weight.

Title: Current collector for railway
Inventor: ISHIZU KAZUMASA
IPC: B61D49/00
Filed: 1994-09-14
Abstract: PURPOSE: To prevent the generation of aerodynamic sound during traveling while suppressing the increase in the weight of a train. CONSTITUTION: Two current collecting shoe elevating mechanisms are installed at a pantograph 2, and the mechanisms and current collecting shoes are eccentrically deviated laterally at a train. Thus, when the two mechanisms are opposed longitudinally of the train, the both can approach to each other, and a pantograph cover 11 for enclosing the pantograph 2 can be reduced in size and weight. When the train is advanced, the two mechanisms are operated, only the rear shoe with respect to the advancing direction is brought into contact with a trolley wire, and the other shoe is retained in a folded state. Thus, an air flow generated by the traveling of the train is jumped up to the oblique surface 11a of the cover 11, thereby suppressing the flowing speed in contact with the shoes and the mechanisms.

Furthermore, the internal constitution of the case 1 has an exactly same function as that of an ordinary mouse with only its external appearance different from the mouse. Thus, an operator can definitely operate the case 1 like an ordinary mouse.

IPC: G11C11/407
Filed: 1991-08-06
Abstract: PURPOSE: To attain a smooth operation even for the fluctuation of a critical voltage despite of low power consumption by using a depletion type FET and an increase type FET as an FET for a load.

Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To stabilize the output voltage of a switching power source so that no overvoltage can be applied across an element which is connected to the power source as a load by detecting in advance the abrupt reduction of the load current of the power source and utilizing the detected signal of the abrupt reduction for controlling the width of a switching pulse. SOLUTION: A logic controller 4 judges the operating state of a load 3 in accordance with a logic control program and, when the controller 4 detects the abrupt reduction of the current consumption of the load 3 in advance, a power source control section 11 drops the reference voltage of a reference voltage input circuit 11c which is the input of an operational amplifier 11b for controlling voltage, and then, reduces the width of the output pulse of a comparator 11a for generating switching pulse. Therefore, the output voltage (g) of a switching power source 1 is dropped by outputting the output pulse of the comparator 11a to the switching transistor 10a of the DC-DC converting section 10 of the power source 1 and, thereafter, the current consumption of the load 3 is abruptly reduced.
