Patent JP-H10154326-A (JP)
Title: Production of magnetic recording medium
Inventor: NAKADA JUNJI
IPC: G11B5/85
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of thermal yielding which is the drawback of high-frequency induction heating and to further improve vapor deposition efficiency with a process for producing a magnetic recording medium by forming magnetic layers of multilayered constitution and an apparatus therefor. SOLUTION: The magnetic material 10A in a first evaporation vessel 16A is heated by an electron beam 31 emitted from an electron gun 30 and the magnetic layer of a first layer is deposited by evaporation on a base film 3. The magnetic material 10B in a second evaporation vessel 16B is heated by a high-frequency induction heating coil 12 and the magnetic layer of a second layer is deposited by evaporation on this base film 3. Charges are accumulated on the film 3 by the electron beam 31, by which the film 3 is brought into tight contact with cooling cans 4A, 4B. The heat by the vapor deposition is made to escape well to these cooling cans 4A, 4B and the thermal yielding of the film 3 is prevented. Further, the vapor deposition efficiency is improved as compared with the formation of the magnetic material of the multilayered constitution by the electron beam alone.

Title: Hole force opening method for molten metal outflow hole and hole force opening device therefor
Inventor: TADA MITSUHIRO
IPC: B22D11/10
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent the contamination of molten metal as packing sand is not used in a molten metal outflow hole by detaching an upper part closing plug from the molten metal outflow hole by a pushing-up rod moved upward by a lower part closing plug and opening the hole of a sliding type opening/closing device. SOLUTION: When a rod 8 is moved upward to the sliding surface of a stationary plate 10 and a sliding plate by a hydraulic cylinder 7, the lower closing plug 4 pushes up the pushing-up rod 6 and comes into contact with the upper closing plug 3. The pushing-up rod 6 rises further and the upper closing plug 3 floats in the molten steel. The molten steel flows successively into an upper nozzle 9. The top end face of the lower closing plug 4 is aligned to the front surface of the sliding plate 11 and the sliding plate 11 is rotated around the axial center A by the hydraulic cylinder 7, by which the outflow hole of the stationary plate 10 and a collector nozzle 12 are mated to allow the molten steel to flow out.  As a result, the packing sand is not used for the molten metal outflow hole and, therefore, their is no contamination of the metal by the packing sand and the mechanical opening by the hole opening device is made possible.

Title: Picture display device
Inventor: IIDA MASAYUKI
IPC: G09F9/00
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To enhance a yield in a manufacturing process and to decrease a failure rate during use. SOLUTION: An external input signal of a counter electrode potential is inputted to PAD 112c of pad groups 112 for external connections. A mass wiring layer 117 is connected with PAD 112c. An external input signal of the precharge signal, etc., is inputted to PAD 112a. A wiring layer 118 of an intermediate capacity is connected with PAD 112a. These wiring layers stay between a guard ring layer 111 and an internal circuit wiring layer 114 of a small capacity internal circuit 114, and an internal circuit 113.  Since the wiring layers are arranged so that a capacitance value becomes smaller from the guard ring layer side to the internal circuit in sequence of a mass wiring layer and a wiring layer of an intermediate capacity, even if electrostatic charges are generated on a large area of the guard ring layer, the influence is eased with the wiring layers successively and does not give electrostatic damage to PAD 112a, 112b, 112c and the internal circuit 113.

Title: Helical scanning method of magnetic tape for recording and executing method of said method
Inventor: YURUGEN KAADEN
IPC: G11B27/32
Filed: 1993-12-13
Abstract: PURPOSE: To read a timer mark even at a high tape speed by dividing time code information into different weighted groups and shifting these groups with respect to space or frequency to record them. CONSTITUTION: The signal on a track S1 has bit information at intervals of 40ms, and a frame signal F indicates an independent area of data recorded on a helical track. This signal is supplied to the servo device of a video signal processing means and is used for synchronization. Three control bits C indicate control information for the whole of the device and follow the synchronizing bits. For example, they are used for the power frequency, the picture aspect ratio, and use of an HD or SD signal for recording. Nineteen bits following them have information related to hours, minutes, and seconds for each group and are counted as a binary and are protected with a parity bit for each group. Nineteen bits following them are expressed in 25% duty ratio in the case of H bits and are expressed in 75% duty ratio in the case of L bits.  Thus, the time mark is read even if the tape is carried at a high speed.

Title: Process variations discriminating circuit and system
Inventor: NAKANO YOSHITO
IPC: H01L21/02
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To automatically discriminate a process variation easily and quickly on each LSI chip basis. SOLUTION: Reference voltages obtained by dividing a voltage VDD from taps T1 to T5 of a reference voltage generation circuit through resistors are applied to gates of transistors TR1 to TR5 to be measured. The transistors TR1 to TR5 are turned on or off, depending on whether the process management widths of the transistors TR1 to TR5 are higher or lower than their gate voltages or within their ranges, which are discriminated by NAND gates ND0 to ND5, which in turn output their discrimination results to terminals A0 to A5 in the form of binary signals of '1' and '0'. Transistors TR6 and TR7 are also turned on or off depending on the presence or the absence of a MOS capacitor, which are also discriminated by NAND gates 6 and 7. Discrimination results are output from the NAND gates to terminals A6 to A7 in the form of binary signals.  The circuit is mounted on each LSI chip, digital discriminating signals indicating the process variations of the chips can be obtained automatically.
