Patent JP-H11150066-A (JP)
Title: Manufacture of semiconductor device
Inventor: MIYASAKA MITSUTOSHI
IPC: H01L21/20
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To manufacture a semiconductor device so that a device may obtain an excellent characteristic at a relatively low temperature, by performing thermal oxidation at a specific temperature in an oxidizing atmosphere in a second process and making the oxidation time of a monoatomic layer longer than the stress relaxation time of an oxidized film. SOLUTION: A silicon oxide film is deposited on a substrate 501 as a substrate protective film 502 by a plasma chemical vapor deposition method. Then, an amorphous silicon film is deposited on the protective film 502 by the low- pressure chemical vapor deposition method and an island 503 composed of a semiconductor film is formed by patterning the formed amorphous silicon film. Next, a silicon oxide film 504 is formed on the surface of the patterned island 503. At the time of forming the silicon oxide film 504, the oxidation of the island 503 is performed by maintaining the same condition (oxidation process) after an oxidation temperature of <1,070 deg.C is reached, so that the thickness and quality of the silicon oxide film 504 may become desired ones and a smooth interface may be obtained between the film 504 and the island 503.  Then unnecessary low-temperature oxidation can be prevented by completely releasing stresses from the oxide film during the oxidizing period.

Title: Regular test guide device
Inventor: HISAJI MASAHIKO
IPC: G05B23/02
Filed: 1985-11-15
Abstract: PURPOSE:To prevent a mis-operation based on a display operation guide, and to improve safety by providing a guide control device at an arithmetic processor, and providing a red and a green flickers so as to be lightened with the controller. CONSTITUTION:For the first, operation items (I)-(III) are estimated, and an arithmetic processor 5 stores each bit of operation information in each item. Each bit of operation instructing information of stored items (I)-(III) is drawn out and displayed on a display device 2 by the request of an operator from a function selection switch 3, and is transmitted to a guide controller 6. The bit of operation indicating information transmitted to the controller 6 lightens either of a red lamp R and a green lamp G as the state display lamp of an operation switch 4, and either of a red flicker R1 and a green flicker G1 as guide lamps 7 and 8 with the control of the controller 6. Therefore, a guide operation can be performed without a fault, and the position of the switch 4 (4c-4g) can be easily confirmed, thereby a required test time being reduced.

Title: Optical information recording and reproducing apparatus
Inventor: OE SHINICHI
IPC: G11B11/105
Filed: 1993-10-13
Abstract: PURPOSE:To set up the focus servo at the position where the focus point is deviated from the center of defocusing of the disk surface in order to avoid the phenomenon that if the focus point is located at the center of the defocusing of the disk surface, the tracking acceleration of an objective lens becomes high when the focus servo is set up, resulting in the possibility of failure of focusing. CONSTITUTION:A relative velocity of the reflecting surface of a disk 2 for the focus point is obtained by differentiating a focus error signal with a differential circuit 20. Only when such relative velocity value is less than the reference value, a focus servo loop is closed by a switching control circuit 13 and a switch 14.

IPC: B62D6/00
Filed: 1993-10-13
Abstract: PURPOSE:To stably perform the control in accordance with the change of the curvature of a road or the vehicle speed and to reduce the calculation volume and the memory capacity. CONSTITUTION:A means 10 which measures a vehicle speed V and a device 30 which measures a vehicle yaw angle (y), a road curvature Cr, and an extent epsilonor transverse deviation as the extent of positional deviation of the vehicle from a reference line of the road are provided. A device 24 multiplies the extent epsilonof transverse deviation and its time differential value by gains and adds multiplication results and outputs the result. A device 22 multiplies the road curvature Cr by a gain and outputs the result. A device 18 outputs a learning signal which determines the gain to be used in a device 20 and is defined by the difference between the command curvature calculated by a means 18A and the running curvature calculated by a means 18B. The device 20 consists of a neural network and uses the learning signal to calculate and output the extent of compensation which reduces the extent epsilon of transverse deviation which is generated because proper gains cannot be set in the device 24.

IPC: H05K3/34
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To increase mounting density of printed wiring board by providing a wiring pattern at the lower part of an insulation layer under a chip part. SOLUTION: A land part 7 narrower than the width of the electrode 6a of a chip part 6 is formed on the surface of the base 5a of a printed wiring board 5. An insulation layer 5b is formed on the base 5a and a window 5c is opened at a part of the insulation layer 5b abutting against the upper surface of the land part 7. The window 5c is narrower than the electrode 6a and wider than the land part 7. In other words, a slight gap is present between the land part 7 and the window 5c. The chip part 6 is mounted on the insulation layer 5b and connected with the land part 7 through the window 5c and the electrode 6a is jointed to the land part 7 through solder. Since the land part 7 and the window 5c are narrower than the electrode 6a, a wiring pattern 8 can be arranged directly below the electrode 6a. According to the structure, wiring density is increased and thereby mounting density can be increased.
