Title: Locking mechanism for recording medium
Inventor: GOTO YOICHI
IPC: G11B33/02
Filed: 1991-11-15
Abstract: PURPOSE:To prevent the takeoff of a recording medium when signals are sent and received between the recording medium and an information processing device by judging the exchange of the signals between the information processing device and the recording medium, and controlling the operation of an electromechanical locking mechanism. CONSTITUTION:The signal exchange state between an information processing part 2 and a recording medium 3 is obtained with a signal-exchange judging circuit 4. When the signals are not sent and received between the information processing part 2 and the recording medium 3, the signal is sent into a control circuit 5. An electromechanical locking mechanism 6 is released by the output from the control circuit 5. When the signal are sent received, the locking mechanism 6 is operated, and the rear surface of the recording medium 3 is pushed. Therefore, even if an ejector 10 for taking out the recording medium 3 is pushed, the recording medium 3 is not taken out.

Title: Outer wall structure of spacecraft
Inventor: YOSHITOMI HISASHI
IPC: B64G1/12
Filed: 1993-11-30
Abstract: PURPOSE:To automatically block up a hole when the hole is bored in an outer wall by collision of cosmic dust, and detect a damaged place easily in a spacecraft such as a space station. CONSTITUTION:A space between a cell inner wall 1a and a cell outer wall 1b constituting an outer wall of a spacecraft, is divided into mutually independent plural cells 21, and air is supplied in the the respective cells 21 through a valve 4, and valves 3, 4 and 5 are made openable in response to pressure reduction in the cells 21 so that two kinds of liquids coagulating when being mixed in the valves 3 and 5 are injected into the respective cells. When a hole is bored by colliding with cosmic dust, pressure inside of the cells 21 is reduced, and the valves 3, 4 and 5 are opened, and the two kinds of liquids injected from the valves 3 and 5 are mixed together by an air flow close to the valve 4, and coagulate, and block up the hole. Damaged places of the cells 21 are detected by pressure sensors 6 of the respective cells 21.

Title: Servo device
Inventor: SUZUKI HARUYUKI
IPC: G11B7/095
Filed: 1993-11-30
Abstract: PURPOSE:To surely detect off-servo and to protect a driving device even if an error signal has nature to turn nearly to zero in positions near a target position and largely apart from this target position by an improvement of device constitution such as provision of an integrated circuit (INT). CONSTITUTION:A DET 5 receives reflected light from the information surface of an optical disk 1, detects the mispositioning between the information surface of the optical disk and the focus of a light spot as a focus error and outputs this focus error as an FE signal. The TNT 7 is inputted with this FE signal, integrates the focus errors and outputs the result thereof to a driving circuit (AMP) 10 through an adder 8 and a switch 9. This driving circuit 10 drives an actuator 4 according to the input signal from at least the INT 7, thereby minimizing the positional error of a lens 3. A WCMP 11, LOGIC 12 and loop switch 9 constituting a driving stop means stop the driving operation by the AMP 10 when the output signal from the INT 7 is off the prescribed range.

Title: Method and device for inspecting transfer defect
Inventor: SHIMADA NOBORU
IPC: G11B7/26
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To rapidly detect and inspect at high speed multiple transfer of a disk like optical recording medium changing the number of division sectors of a circuit according to a radial position. SOLUTION: An optical pickup 11 scans a laser beam L along to a groove on the signal recording surface of the optical disk 1 changing the number of division sectors of one circuit according to the radial position. A signal processing circuit 12 calculates a sum signal or a difference signal from a reflection laser beam from the signal recording surface. A decision circuit 13 decides a size of a leakage signal due to dragging of an address pit at a forming time observed on the sum or difference signal calculated by the signal processing circuit 12.

Title: Manufacture of semiconductor device
Inventor: OONUMA NORIHIRO
IPC: H01L21/302
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To reduce the contact resistance between lower-layer wiring and upper-layer wiring formed in a succeeding process by sufficiently removing substrate damages at the time of performing dry etching on a film made of an SiOx-based material on the lower-layer wiring composed of a film of an Si-based material. SOLUTION: After a via hole is formed through an SiOx interlayer insulating film to a polysilicon wiring pattern below the insulating film by etching the insulating film with a fluorocarbon gas, a damaged polysilicon layer formed on the bottom of the via hole and a deposited layer composed mainly of a carbon-based polymer are removed by performing chemical etching with a CF4 /O2 mixed gas containing CF4 at a flow rate ratio of 40-60%. When the damaged layer is removed in such a way, the growth of a suboxide (Si-rich SiOx) in a succeeding process can be suppressed and a low-resistance contact can be formed, because the damaged layer can be removed sufficiently without excessively eroding the polysilicon.

Abstract: PROBLEM TO BE SOLVED: To shorten the total length of a clutch by concentrically and interposingly arranging in the shaft direction, a fitting part of a clutch drum inside surface and a clutch piston outside surface and a fitting part of a clutch piston inside surface and a cancel piston. SOLUTION: A clutch plate 5 is arranged in a clutch drum 1, and a clutch disc 6 is arranged in a clutch hub 2, respectively, and they are connected to and separated from each other by a clutch piston 3.
