IPC: B05D7/00
Filed: 1982-09-02
Abstract: PURPOSE:To improve water proof, dust proof and antioxidation properties of a paint coating for outdoor stacks such as coal by sprinkling a predetermined amount of the total paint amount to be sprinkled from the upper side of the stack and the residual amount from the lower side. CONSTITUTION:When an outdoor stack such as coal is covered with a coating paint which becomes insoluble after dried, the total amount of the paint is determined from the surface area and coating thickness of the stack to sprinkle 50-75% of the paint from the upper portion side of the outdoor stack through a nozzle. At the remaining paint is sprinkled with the nozzle directed obliquely upward or horizontally while moving around the bottom of the stack. Thus, a continuous coating is satisfactorily formed to improve water proof, dust proof and antioxidation properties of the stack.

Title: Failure memory device for combustion apparatus
Inventor: EMURA YUICHI
IPC: F23N5/24
Filed: 1988-06-22
Abstract: PURPOSE:To allow holding of the contents of failures stored even when the power is not supplied to a failure memory device by writing the contents of failures to a non-volatile memory. CONSTITUTION:When a failure detecting device 4 detects a failure, a signal corresponding to the content of the failure is input to a microcomputer 2, and a writing device 2a writes the content of the failure to a non-volatile memory 3. On the other hand, every time a switch 6 is pressed to display the written content of the failure on a failure annunciator 5, a reading device 2b of the microcomputer reads the content of the failure from the non-volatile memory, and a failure annunciator operating device 2c outputs the content of the failure to the failure annunciator to display it. The non-volatile memory requires power supply to write, however, power supply is not necessary to hold the contents of failures written so that the contents of failures are not lost even if the power supply is cut off.

IPC: H01S3/094
Filed: 1990-06-14
Abstract: PURPOSE:To attain high conversion efficiency by realizing single mode processing of both space characteristics and spectral characteristics of two basic waves. CONSTITUTION:A non-linear optical element 6 is arranged at a beam waist position in the inside of a solid state laser resonator having rectangular bending structure which consists of a resonator mirror 1, a YAG laser element 2 as a solid state laser element, a dichroic mirror 3 of 45 deg. incidence, a wavelength selecting element 4 and a dichroic resonator mirror 5. Oscillation light of an excitation semiconductor laser 7 is converged, and the YAG laser element 2 is side-excited for resonance between the resonator mirror 1 and the resonator mirror 5 to oscillate YAG laser; then, oscillation is realized at a single wavelength by the wavelength selecting element 4 inside a resonator. Furthermore, single wavelength oscillation and sum frequency light of YAG laser can be acquired simultaneously; therefore, arrangement of the wavelength selecting element 4 is limited, and single mode beam can be acquired as for space characteristics of YAG laser beam by a countermeasure such as arrangement of a circular opening inside a resonator if necessary. Accordingly, it is possible to produce sum frequency light effectively and to acquire high conversion efficiency.

Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent the collection of working chips by a short-circuit current, and reduce the flow generated on the surface of a workpiece in powder electric discharge machining by stopping the application of a working pulse when a short-circuit is caused between an electrode and the workpiece. SOLUTION: When a working form is complicated, the circulation of a working fluid 11 in a working part is deteriorated to make the discharge of working chips difficult. When the discharge of working chips is not satisfactorily performed, powder 113 and the working chips are stayed between an electrode 102 and a workpiece 103 and apt to cause a short-circuit. When a short-circuit is caused between the electrode 102 and the workpiece 103, the output of a short-circuit detecting circuit 106 becomes 'L'. Therefore, the output of an OR circuit 110 becomes 'L', and the output of an AND circuit also becomes 'L'. Consequently, a switching element 104 is laid in OFF state to stop the application of voltage.

Abstract: PURPOSE:To obtain a graphic input device having high stability to the fluctuation of operation by averaging the writing pressure of a pointer over a graph and comparing this writing pressure with the boundary pressure to obtain the corresponding color information and then to decide the color of the graph. CONSTITUTION:A pressure position input part 3 consists of a pointer 4, an input surface 5 and a control part 6. The pressure information and the position information are produced when an operator operates the pointer 3 containing a strain gauge on the surface 5. The pressure information is sent to an average pressure calculating circuit 7. The circuit 7 adds the pressure information sampled between the start and the end of input and dividing the integrated value by the sampling frequency when the input is through to obtain the average value. This average value is sent to a color deciding circuit 8 and compared with the contents of a boundary pressure memory to obtain the pressure level information. Then the color information corresponding to the pressure level is read out of a color information memory 10. Thus it is possible to decide the color or a graph from the average value of the writing pressure of the graph.

Filed: 1985-07-12
Abstract: PURPOSE:To set optionally a hysteresis width by connecting transistors TRs different in emitter area between the earth and emitters of a pair of TRs whose bases an input voltage is impressed to differentially. CONSTITUTION:A TR 12 is provided, and the collector of the TR 12 is connected to the emitter of a TR 2 and the base of a TR 4, and the base of the TR 12 is connected to the anode of a diode 9 and the base of a TR 10, and the emitter of the TR 12 is grounded. Emitter areas of TRs 10 and 12 are (n) times and (m) times as large as that of a TR 11 for constant current source. By this circuit constitution, a hysteresis width V3-V4 (V3 and V4 are base voltages of TRs 3 and 4) is not dependent upon current amplification factors of TRs but dependent upon the emitter area ratio of the TR 10 to the TR 12. The variation of the hysteresis with due to temperature can be ignored. Thus, the hysteresis width can be set to an optional value determined only by the emitter area ratio of TRs.
