Title: Manufacture of semiconductor device
Inventor: ABE RIYOUJI
IPC: H01L21/768
Filed: 1984-05-31
Abstract: PURPOSE:To prevent the occurrence of discontinuous lines in growing of a cover film, to improve moisture resistance and to prevent the occurrence of cracks, when the cover film is formed on a wiring, which is formed on an insulating film of a semiconductor substrate, by forming a liquid phase oxide film by a spin coating method, and burying the difference in steps of wiring edges. CONSTITUTION:An insulating film 12 is formed on a semiconductor substrate 11 by an ordinary technology. On the insulating film, e.g., an aluminum wiring 3 is formed. In the present invention, a cover film is not directly formed, but a liquid phase oxide film 14 is formed. The liquid phase oxide film is formed by, e.g., the following way: hydrochloric acid is added to methyl silicate: alcohol is added to said mixture as a solvent; the mixture is applied on the substrate by a spin coating method; then baking is performed at 450 deg.C; the solvent is removed; the methyl is removed by a chlorine group; and silicon dioxide is hardened. Then, e.g., PSG is grown and a cover film 15 is formed. Since the film 15 is grown on the gentle surface, the occurrence of discontinuous lines is suppressed.

IPC: B23K26/064
Filed: 1992-04-30
Abstract: PURPOSE:To carry out accurate machining of a specific shape on a work piece by converging a laser beam with a lens having a specific shape. CONSTITUTION:When a silicon nitride sintered ceramic plate 2 is irradiated with a KrF excimer laser beam (248nm wave length, 30nsec pulse width) through a conical lens 1a made of a molten quartz, a ring with an inner diameter of 50mum and a width of 200mum is drawn. By a 500 pulse irradiation with an energy of 4J/cm<2>, a groove with a depth of 45mum is formed. By this method, a laser abrasion is activated only in a ring shaped area, and an annular grooving can be performed without moving a sample 2. The annular diameter is adjusted by varying a distance between the lens 1a and the sample 2, and the annular width is adjusted by varying the apex angle alpha or the refractive index of the conical lens 1a. In addition, if the shape of the lens is made cylindrical, a linear spot is obtained; and if a triangular prism, a parallel spot is obtained.

Title: Program loading system
Inventor: KIKUCHI KAZUFUMI
IPC: G06F9/445
Filed: 1985-05-27
Abstract: PURPOSE:To improve the memory efficiency and to increase an execution speed by providing an external storage device string a load program which transfers a processing program and the data on the execution mode to a main storage. CONSTITUTION:A data program 6 converts the basic language into the execution mode data 7 by an initialization program 4 and stored in an external storage device 1. When a data processor executes a processing program, a data load program 3 and a processing program 5 stored in the device 1 are loaded to a main storage RAM 2 for execution of the program 3. The data 7 is loaded to the RAM 2 and the processing program is executed. Thus the executing time of the program 5 is shortened and it is not needed to store both programs 4 and 6 in the RAM 2. As a result, the memory capacity is saved since the program 3 is smaller than the program 4.

Filed: 1979-08-31
Abstract: PURPOSE: To obtain a synthetic resin sheet whose surface is in an excellent condition by a method wherein a doctor blade for peeling off a synthetic resin material wound round a roll is moved up and down along the roll in accordance with the surface temperature of the roll.  
     CONSTITUTION: A heated synthetic resin material 1 is passed through between a roll 2 and a lower roll 5. When the surface temperature of the roll 2 exceeds the set temperature, it is detected by a temperature sensor 8 and the doctor blade 4 is moved downward, thereby the quantity of the wound synthetic resin material 1 being reduced, thus the amount of heat transferred from the synthetic resin material 1 to the roll 2 being reduced, and the surface temperature of the roll 2 being lowered to the set temperature. In the case contrary to this, the doctor blade 4 being moved upward, the amount of heat transferred to the roll 2 is increased and thus the surface temperature is raised to the set temperature. By doing this, the surface of the synthetic resin sheet can be finished to be in a uniform condition.

Title: Fm radio equipment with voice control
Inventor: TAKANO TAKESHI
IPC: H04B1/10
Filed: 1986-05-15
Abstract: PURPOSE:To prevent the generation of noise and to decrease power consumption of a transmitter by providing a control signal generating means on a transmitter of an FM radio equipment and a voice output changeover means connecting/ disconnecting a reception sound output on a receiver and allowing the receiver to output a sound signal for a period when the sound signal is received depending on a control signal from an opposite transmitter. CONSTITUTION:A voice control means 16 provided on a transmitter detects a sound signal, impresses a power to a transmission section 5 for a period of the sound signal to operate a transmission section. Further, a control signal generating means 14 slices a transmission sound signal outputted from a microphone 1 at a prescribed level to form two pulse control signals corresponding to the leading/trailing of the sound signal. On the other hand, a sound output changeover means 15 provided on the receiver turns on/off a low frequency amplifier section 11 by using a control signal corresponding to the leading/ trailing received from the transmitter thereby operating a low frequency amplifier section only for a period receiving the sound signal. As a result, a noise generated when a conventional carrier is lost is shut completely to reduce remarkably the power consumption.

Title: Memory back-up circuit
Inventor: KOMODA YOSHIYUKI
IPC: G06F1/00
Filed: 1985-05-25
Abstract: PURPOSE:To cut off a malfunction pulse and to prevent the destruction of the memory contents by putting a flip-flop circuit between the output terminal of the 1st delay circuit and the chip enable terminal of a memory. CONSTITUTION:A flip-flop 9 which receives the supply of power from a memory back-up battery 6 is put between the output terminal of the 1st delay circuit 3 and the chip enable terminal CE of a memory 5. The flip-flop 9 is set by an output port 10 of a CPU 2 and then reset by the reverse output of the circuit 3. Therefore the chip enable signal is delayed to the memory 5 only when a power supply is turned on. Thus a malfunction pulse is cut off and therefore no trouble is produced while the power supply is kept off.

Abstract: PROBLEM TO BE SOLVED: To reduce the execution time by generating a window of a specific size for pattern matching and referencing a table registering a window pattern in advance when any matched pattern is not in existence. SOLUTION: A control section 9 segments a picture element group of 9.8 picture elements from an image bit map memory 3 and stores it to a matching pattern memory 4. A window of 3.3 picture elements consisting of a center picture element and its adjacent picture elements is segmented and weighting is applied to each picture element value in the window in response to the position of the picture elements and the results are summed to calculate hash values of 0-511 corresponding to kinds of all patterns. The control section 9 collates data of a template data storage section 6. and corrects the pattern with data in a correction data storage section 7 when they are matched. However, since lots of patterns without corresponding templates are in existence actually, the table 5a of the hash values is provided to a matching processing section 5.
