Title: Pulverized coal burning device
Inventor: ORIMOTO MANABU
IPC: F23K1/02
Filed: 1986-09-08
Abstract: PURPOSE:To secure a steady burning condition even if the load is low for a coal pulverizer by attaching a vent tube to the pulverizer to allow the extraction of a certain amount of primary air, and regulating the amount of extraction relative to the reduction of load. CONSTITUTION:In a case where the load fluctuation is to be coped with by a burner cut, the amount of finely pulverized coal flowing into the vent air is minimized since the inlet of the vent tube concentrically disposed relative to the coal feed pipe 28 is placed in an area where the coal concentration is leanest in the classifier due to the centrifugal force. Therefore, the rate of venting can be regulated corresponding to the number of burners which are cut off, and so the amount of primary air to the burners in use does not increase unnecessarily. The extracted vent air is supplied to a cyclone separator 6 to separate finely pulverized coal contained therein. This way, the coal/air concentration is raised, and the burner nozzle speed reduced, by starting venting. In this manner, a high coal/air concentration can be maintained, and the burner nozzle speed maintained at a proper level, even under low load conditions.

Filed: 1990-08-08
Abstract: PURPOSE:To form an LDD structure by one implantation process by a method wherein a gate electrode is formed by making use of a metal thin film as a mask, ions are implanted into a wafer and the metal thin film is removed. CONSTITUTION:A polycrystalline silicon film 104 is formed of a gate-electrode interconnection material; and an aluminum thin film 105 is formed on the polycrystalline silicon film by a sputtering operation or a vapor deposition operation. Then, a resist is patterned. Then, a gate electrode interconnection is patterned by a dry etching operation by making use of the aluminum film as a mask. Then, an ion beam of B ions, P ions or the like is irradiate; and a source-drain region is formed. Since the aluminum thin film acts as a mask in a part near the end of the gate electrode, the part becomes a shallow low- concentration diffusion layer 107. Lastly, the aluminum thin film on the gate electrode is removed by using an etchant, and an LDD structure is formed.

Title: Magnetic tape device
Inventor: MAEJIMA MITSURU
IPC: G11B5/09
Filed: 1989-08-14
Abstract: PURPOSE:To enforce the efficiency of using a magnetic tape by erasing the data on a recording position by an erasing circuit in the case that the data is recorded on the recording position to be accessed by the different type of devices and writing the data on that position based on information in a system area at the time of writing the data. CONSTITUTION:In the case that writing command is given by a host device, whether preceding data to be recorded on a specified stripe on which the data is written by the other type of the devices or not is checked by volume control information stored in a memory 2. In the case that the data is written by the other type of the devices, the erasing circuit 7 is driven so as to output a high AC to a writing heat 10 and to move the magnetic tape 22, therefore, a high AC magnetic field is received at the time of passing through the gap part of the writing head 10, and a data signal which is recorded after being once magnetized to be in a saturated state is completely erased. After erasing, the data is written. Thus, a cartridge tape on which the data is written by the lower rank type of the devices having a low recording frequency can be used as it is, and the efficiency of using the magnetic tape 22 can be enforced.

Abstract: PURPOSE:To measure the length of crack accurately by applying load repeatedly by predetermined times on a test piece while keeping constant the variation of stress intensity factor and the ratio between maximum and minimum values thereof thereby setting a constant interval of beach mark. CONSTITUTION:A test piece 7 is set in a test equipment and a computor 4 commands a controller 5 to operate an actuator 1 such that the maximum and minimum values of repeating load and the ratio therebetween are kept constant. When the repeating load is applied by predetermined times, load signal of a load cell 2 and opening dispacement (COD) from a strain gauge 3 are inputted in order to determine a compliance value C and a crack length (a) thus calculating DELTAK, i.e., the difference between maximum and minimum stress intensity factors. Repeating load is applied while keeping the DELTAK constant and the ratio between minimum and maximum loads at 0.1 and the compliance is measured when the load-is applied by predetermined times. Subsequently, Kmax is kept constant and the DELTAK' is kept constant at DELTAK/2 and the load is applied repeatedly on the test piece 7. A beach mark is then inserted, the test piece 7 is separated vertically, crack length (a) from the mark position to each position is measured and combined with the compliance value to determine the coefficients thus calibrating the measurement of crack length.

Title: Reader
Inventor: WATANUKI HIROSHI
IPC: G06K7/01
Filed: 1981-12-26
Abstract: PURPOSE:To reduce read errors, by providing a means which blows a hot blast to the read surface of a read window. CONSTITUTION:A blow hole 9 is provided throughout the overall length of one side of a window glass 5a in the side of a read window on the upper face of a reader 1. Discharge air generated by driving of a fan which cools the heating of each unit in the reader 1 is led to the blow hole 9. In this constitution, when the reader 1 is used, air absorbs heat generated in internal units by driving of the internal cooling fan and becomes a hot blast and is led to the blow hole and is discharged onto the window glass 5a in the direction of arrows. Consequently, dust is difficult to stick to the window glass 5a, and stuck dust is blows off. When the surface of the window glass 5a is wet with the water drop, the drop is vaporized with the hot blast to dry the surface. Thus, the read surface is kept clean to reduce read errors.

Abstract: PURPOSE:To obtain a world timepiece of a hand display by generating a motor driving signal, by a relative time difference generating circuit, corresponding to a relative time difference of a place name which is inputted by a place name input switch of the world, and a place name which has been inputted previously. CONSTITUTION:A signal which becomes a time standard is outputted from an oscillating circuit 1 and frequency-divided by a frequency dividing circuit 2, and by using this frequency divided signal, a motor 4 is driven by a motor driving circuit 3, and the time is displayed by the hand. In this case, for instance, when the time of London has been displayed, if Paris is inputted by a place name input switch 6, a relative time difference generating circuit 5 generates a signal of + one hour, based on a signal of the circuit 2, so that the time display by the hand is advanced by one hour. In this way, by displaying the time of the inputted place name, a world timepiece by the hand display can be obtained.
