Inventor: TANAKA TAKAO
IPC: H01L21/225
Filed: 1988-03-30
Abstract: PURPOSE:To form a diffused layer uniformly and with good reproducibility by heat treating by a laser light in vacuum. CONSTITUTION:An oxide film doped with an impurity therein is formed on a semiconductor wafer 12, and with the oxide film as a diffusion source an impurity diffused layer is selectively formed on the wafer 12. That is, it is heat treated with carbon oxide gas laser light 8 of the wafer 12 in vacuum. Thus, since the wafer 12 is irradiated with the light 8 to diffuse the impurity of a small part, no dust is generated due to a friction as in case of using a quartz jig, and since it is treated in high vacuum, the impurity is not mixed from heat treating gas, and no disturbance of the gas occurs. Thus, a predetermined diffused layer can be formed uniformly on the wafer with good reproducibility.

Title: Supercharger for internal-combustion engine
Inventor: NAKANO HIDEAKI
IPC: F02B37/18
Filed: 1983-05-06
Abstract: PURPOSE:To prevent a supercharger from abnormal load by detecting the rotational condition and back pressure of an exhaust gas turbine to control a bypass valve and vary exhaust back pressure. CONSTITUTION:When exhaust back pressure is abruptly reduced during the continuous running of an internal combustion engine 1, the rotational speed of an exhaust gas turbine 7 is increased. Sensors 11, 13 detect respectively the increase of the rotational speed and the decrease of exhaust back pressure and send the respective signal to a controller 12. The controller 12, upon receiving the signals, compares the detected value of the signal with set values from a rotational speed setter 14 and an exhaust back pressure setter 15 to open a bypass valve 10 according to the degree of the detected value. When exhaust back pressure is abruptly increased during the continuous running of the internal combustion engine 1, the rotational speed of the exhaust gas turbine 7 is abruptly reduced. In this case, the bypass value 10 is closed according to the degree of the detected value reversely to when the exhaust back pressure is reduced.

Filed: 1990-03-28
Abstract: PURPOSE:To eliminate risk of loosening by vibration, etc., even though a large pitch screw is used to a fitting means by furnishing a round form connector with a click lock means in which a projection falls in a recess when fitting of the connector is completed. CONSTITUTION:When a coupling ring 12 is rotated, first a ring 12 solely is advanced by a fitting means toward a receptacle conductor. This is followed by reduction of the distance between the flange pressing part of the ring 12 and a flange 113 of a plug shell 11 to cause compression of an undulate ring- shaped spring 21 pinched by the flange and the flange pressing part. This spring 21 is equipped with a projection confronting the rear end face of the flange 113. Because the spring 21 rotates in a single piece with the ring 12, the projection collides with the flange 113 and slides. The plug shell 11 is inserted in the receptacle shell, and an electric contact is fitted. In the condition that fitting of the connector is completed, the projection of the spring 21 mates with the recess in the flange 113, so that fit is achieved with a clicking sound.

IPC: B41J2/375
Filed: 1979-06-26
Abstract: PURPOSE:To obtain a thermal head wherein a heating dot part is prevented from being heated high sharply, the heat radiation is expedited and high-speed driving is enabled, by reducing the thickness of a heat-insulating layer just below the heating dot part. CONSTITUTION:An electrode layer 4 is formed in such a way that a heat-insulating layer 2 (ex: glass) is formed on a heat-resistant insulating substrate 1 (ex: alumina substrate), whereon a heating-registant element layer 3 generating Joule heat is formed, on which a heating dot part 3' is further formed, and an abrasion resisting layer 5 is also provided. In this case, the partial thickness of the heat-insulating layer 2 just below the heating dot part 3' is removed partially or completely by etching or other means. Since the thickness of the heat-insulating layer 2 is reduced or eliminated, heat radiation is promoted and the peak (T3) of surface temperature is rather lowered even when heating to high temperature is made for high-speed driving. As a result, the life of the heating-resistant element layer, etc. is prolonged and the high-speed driving (short pulse driving 2m sec or less) turns so far possible.
