Patent JP-H0923007-A (JP)
Title: Semiconductor device and its manufacture
Inventor: NAGANO TAKASHI
IPC: H01L29/78
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of short circuits between transistors and, at the same time, flatten the surface of a semiconductor device by forming an element separating insulating film, a gate electrode, a first conductive layer, and a second conductive layer so that the surfaces of the film, electrode, and layers can be nearly flushed with the surface of a semiconductor substrate. SOLUTION: The level difference between an element separating insulating film 14 which separates a first area 12 and a second area 13 from each other and a gate electrode 23 which is formed in the first and second areas 12 and 13 is almost eliminated in a state where the electrode 23 is conducted, because the area 14A of the insulating film 14 in which the gate electrode 23 is formed is formed at nearly the same height as that of the surface of a semiconductor substrate 11. Consequently, the level difference caused by the gate electrode 23 passing on the insulating film 14 is eliminated. In addition, since the surfaces of first conductive layers 33 and 34 and second conductive layers 43 and 44 are nearly flushed with the surfaces of the electrode 23 and film 14, the level difference caused by the electrode 23 and the surface of a semiconductor device 1 is almost eliminated.

Title: Disk discriminating method and device
Inventor: MATSUSHITA KATSUHIKO
IPC: G11B7/09
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To accurately discriminate plural kinds of disks having different recording formats of recorded signals respectively from an output of an optical pickup even in the case of optical recording media having about the same reflectivity such as the DVD(R) and the CD and also to surely discriminate whether a disk is a single layer or plural layers such as the single DVD and the dual DVD. SOLUTION: In the disk discriminating method for discriminating plural disks 6 having different recording formats, the kind of the disk is discriminated by comparing a ratio of an output level of the max. amplitude of an HF signal obtained by rotating the disk 6 to the min. amplitude level with a 1st prescribed value. Then, when the ratio of the max. amplitude output level of the HF signal to the min. amplitude level is larger than the 1st prescribed value, the kind of the disk is discriminated by the number of crests or troughs of a focus error signal. Then, in this case, the kind of the disk 6 can also be discriminated by comparing the max. amplitude level with a 2nd prescribed value.

Title: Recorder
Inventor: OOTSUKA HIROYUKI
IPC: G11B27/30
Filed: 1981-10-27
Abstract: PURPOSE:To surely perform recording, by operating a pseudo signal generator and using its output, when a synchronizing signal from a video signal is not oibtained or unstable. CONSTITUTION:An output from a synchronizing signal separating circuit 1 is inputted to an input (b) of an OR circuit 5, the output drives a monostable multivibrator 6 and is applied to a base of a signal storage transistor 2. A time constant circuit C, R having a longer time constant than the period of an synchronizing signal is connected to the emitter, and the input to an inverter 3 is taken as 1 and the output as 0. Thus, an oscillator 4 is inoperative. If the output of the circuit 1 is unstable or includes only an audio signal, the input to the inverter 3 is 0, the output goes to 1, the oscillator 4 is operated, and the output is inputted to an input (a) of the OR circuit to drive the multivibrator 6. Thus, even if the synchronizing signal is unstable or only audio signals are recorded from television signals, the recording can be done stably.

Title: Manufacture of semiconductor substrate
Inventor: SHIMODA KOICHI
IPC: H01L29/732
Filed: 1988-07-13
Abstract: PURPOSE:To build a narrowed isolation layer pattern by a method wherein the entirety planned for a plurality of buried layers is formed, provided with a first impurity concentration, and only the upper part of a buried layer to be provided with a second impurity concentration is subjected to oxidation, and finally the layer is provided with the second impurity concentration. CONSTITUTION:A first and second buried layers 3 and 4 are formed, both provided with the impurity concentration of the first buried layer 3, which is quite high. A concentration-reducing process follows wherein the second buried layer 4 is selectively reduced in impurity concentration, with the first buried layer 3 remaining high in concentration. In this design, only one mask serving in the process of forming a high-concentration buried layer is used for processing both low-concentration and high-concentration layers involved in pattern formation. The result is a method free of mask deviation as in a conventional method using different masks for different concentrations. This dispenses with the need for tolerance to compensate for mask deviation. Accordingly, in the process of forming a P<+>-type isolation layer 10, there will be no deviation between a tolerance region and a buried Iayer, which narrows down an isolation layer pattern.

IPC: B22D11/10
Filed: 1994-07-26
Abstract: PURPOSE:To surely prevent the sticking of alumina to an immersion nozzle, to enable multi-sequential continuous castings and to improve the continuous casting operation and the quality by specifying the cross sectional area of the inner hole of a refractory-made pipe, at the time of supplying molten steel in a ladle into a through the refractory-made pipe. CONSTITUTION:When the cross sectional area of the inner hole of the refractory-made pipe 2b is smaller than the total area of the inner hole of an immersion nozzle 5, the supply of the molten steel 4 into the tundish 1 from the ladle 3 can not follow the casting speed and therefore, the cross sectional area of the inner hole of the refractory-made pipe 2b is made the same area or larger as the total cross sectional area of the inner hole of the immersion nozzle. Further, when the cross sectional area of the refractory-made pipe 2b becomes larger, the contact between the molten steel 4 and the refractory-made pipe 2b becomes insufficient, and the removal of the alumina inclusion in the refractory-made pipe 2b becomes insufficient to develop the clogging of the immersion nozzle 5 and therefore, the cross sectional area of the refractory-made pipe 2b is made to be < 4 times of the total area of the immersion nozzle 5. Therefore, the sticking of the alumina can be prevented.
