Patent JP-H0246770-A (JP)
Title: Semiconductor device
Inventor: KATO JURI
IPC: H01L21/762
Filed: 1988-08-08
Abstract: PURPOSE:To obtain a thermal oxide film and a diffusion layer which are durable to mechanical stress and thermal stress, and excellent in breakdown strength, by specifying oxygen concentration of an Si substrate and that of an upper layer Si thin film forming the device. CONSTITUTION:The oxygen concentration of an Si substrate is so high as 10<17>-10<19>cm<-3>, and that of an Si thin film on SiO2 is so low as 10<17>cm<-3> or less. For example, the oxygen concentration of a CZ growth Si substrate 1 is about 10<18>cm<-3>. The oxygen concentration of an FZ growth Si substrate 2, in which SiO23 is formed by oxidizing the surface, is equal to or less than 10<16>cm<-3>. These substrates 1 and 2 are stuck each other and bonded by heat treatment, Then, by polishing the FZ growth Si substrate 2, a thin film Si layer 2' of 0.1-10mum thick is formed. In such an SOI substrate, the Si thin film 2' is constituted of FZ growth Si of low oxygen concentration, and the Si substrate 1 occupying the most part of wafer volume is formed by CZ growth Si of high oxygen concentration. The SiO2 film 3 may be formed on the CZ Si substrate 1.

Title: Fan unit of elevator cage
Inventor: OBARA HIDEYA
IPC: B66B11/02
Filed: 1992-07-24
Abstract: PURPOSE:To damp a vibration attendant upon the rotation of a fan so effectively by interposing an added weight rigid body, being at least two times over fan weight, between a vibro-isolator and the fan, in a device which installs the fan on top of an elevator cage via the vibro-isolator. CONSTITUTION:In an elevator cage additionally provided with a fan unit in order to ventilate an inner part of this cage, plural pieces of rubber vibro- isolators are annularly installed on top of an opening part 5a formed in a ceiling board 5 of the cage, and a soft steel plate 2 as an added weight rigid body having at least two times over the weight of a fan, is attached to each top of these rubber vibro-isolators 3. In succession, this fan 1 is locked to a top face of this soft steel plate 2 after turning its blow-off side downward. With this constitution, a vibration produced by rotation of the fan 1 is made dampable by the soft steel plate 2 without heightening any rigidity in the ceiling board of the elevator cage, an unpleasant feeling and a malaise to be imparted to passengers in an elevator are eliminated in this way.

Filed: 1988-08-09
Abstract: PURPOSE:To shorten a time necessary for the control of a rolling position and improve the tracking performance of the title missile by a method wherein steering aerofoils and a steering system are connected to a fuselage through bearings and the control of the rolling position of only the steering aerofoils and the steering system is permitted. CONSTITUTION:When a guided missile is flying with the rolling position of 0 deg. and a target is found in a direction Z, a steering system 3 is controlled to the rolling position of 45 deg. whereat the maximum turning acceleration is obtained and, thereafter, the missile is turned. A signal for controlling the rolling position is given to a driving device 4 from a cable 8 through a slip ring 6 and a slip ring terminal 7. The driving device 4 steers steering aerofoils 2 in accordance with the roll control signal. A rolling moment is generated by an aerodynamic force by the steering of the steering aerofoils 2 and a torque is exerted on the steering system 3, however, the steering system 3 is connected to a fulelage 2 through bearings 5 and is free from the rolling motion and, therefore, only the steering system 3 effects the rolling motion. Steering for the turning is effected after the steering system 3 has arrived at the rolling position whereat the same device 3 generates the maximum turning acceleration.

Title: Cassette mounter
Inventor: KUMAGAI KIYOSHI
IPC: G11B15/665
Filed: 1993-07-19
Abstract: PURPOSE:To conduct lid opening operation surely with a simple constitution. CONSTITUTION:A cassette holder is moved vertically by sections 6, 7 on a lid opening member in the state in which the side plate 8 of the cassette holder is held. Since a lid-opening member body 3 is supported by giving a backlash on a reel chassis (the vertical direction of a paper surface), on the other hand, cassette mounting operation is conducted as the relative positions of a cassette lid 1 and an opening pin 4 are left as they are kept constant. That is, even when cassette mounting operation is performed by lateral pushing, the lid opening pin 4 is shifted while following the deformation in the lateral direction of the cassette holder, thus preventing the disengagement of the engagement of the lid pin 4 and a cassette-lid end face 16, then carrying out positive lid opening operation.
