Title: Combustion cylinder for petroleum stove
Inventor: NAKAMURA KAZUHARU
IPC: F23D3/02
Filed: 1980-01-31
Abstract: PURPOSE: To stabilize the combustion and enable flames to adhere to the perforated side of an outer combustion body by a method wherein a plurality of horizontal ribs projected toward an inner combustion body are provided at the central and upper parts of the outer combustion body where throat area ratio is high.  
     CONSTITUTION: The plural horizontal ribs 5 projected toward the inner combustion body 2 are provided at the central and upper parts of the outer combustion body 3 where the throat area ratio is high, thereby partly deforming the draft in the gap between the combustion bodies 2, 3. Due to the ribs 5 being provided on the side of the body 3, the mixture gas and the combustion gas flowing upward in the gap between the bodies 2, 3 are provided with higher velocities at positions closer to the inner combustion body 2 and lower velocities at positions closer to the outer combustion body 3. Accordingly, in the area close to the body 2 where the gases flows upward at higher velocities, the pressure in the gap between the bodies 2, 3 is lowered by a larger amount as compared with the case when the ribs 5 are not provided. Therefore, large amounts of air is fed through small holes 2' and the combustion proceeds rapidly.

Title: Manufacture of solid electrolytic capacitor
Inventor: IDA TAKASHI
IPC: H01G9/032
Filed: 1990-01-19
Abstract: PURPOSE:To improve the rate of capacitance achievement by a method wherein, after a semiconductor mother liquor has been impregnated, it is solidified, a solvent-removment by vacuum treatment is repeated a plurality of times, and a thermal decomposition process is conducted at least one or more times. CONSTITUTION:When a semiconductor layer consisting of manganese dioxide is formed, after semiconductor mother liquor has been impregnated, the liquor is solidified, and after a solvent removing vacuum treatment has been repeated a plurality of times, a thermal dissolution process is conducted at least once or more times. To be more precise, as the quantity of semiconductor consisting of manganese dioxice formed by thermal decomposition process is increased, the number of thermal decomposition process is reduced. Accordingly, leakage current is reduced and a semiconductor layer, having manganese dioxide infiltrated into the fine holes of a sintered body, can be formed. As a result, the rate of capacitance achievement can be improved.

Title: Working state monitoring device of pulse laser machine
Inventor: KANEHARA YOSHIHIDE
IPC: B23K26/00
Filed: 1988-01-21
Abstract: PURPOSE:To monitor a work and its working state even while under laser machining by opening and closing the shutter means provided at the front of the TV camera photographing the state of a working part with the oscillation of a pulse laser light and specified timing by a driving circuit. CONSTITUTION:When the pulse signal for generating a pulse laser light 2 from a pulse signal generator 15 is input to a transmitter 55 as well as feeding it to a laser oscillator 1, a driving signal is transmitted toward an amplifier circuit 53 from this oscillator 55 and a PLZT optical shutter 10 is subjected to an opening and closing operation electrically with the specified timing. The strong light generated by the pulse laser light 2 is therefore shielded by closing the shutter 10 during the generation of the pulse laser light 2 and the working state is made to be observed by releasing it in the period of no generation, hence not only the working part but also its circumference can be monitored well during working.

Title: Power supply voltage control type amplifier
Inventor: NAKAGAKI HARUSHIGE
IPC: H03F1/02
Filed: 1982-01-29
Abstract: PURPOSE:To improve the power efficiency, by turning on and off a switch FET in a self-exciting way while suppressing the maximum pulse width of the output of comparison between the power supply voltage and an input signal and then varying the power supply voltage in response to the input signal. CONSTITUTION:When a feedback signal (vi) is lower than the reference voltage (ei) of a voltage comparator 43, the comparator 43 delivers the positive voltage. At the same time, a pulse waveform shaping circuit 45 also delivers the positive voltage to give conduction to a switch FET25. As a result, a diode 28 conducts, and the output voltage passed through a filter circuit 10 rises up to reach the potential higher than the level of the voltage (ei). Thus the output voltage of the comparator 43 is inverted into the negative voltage, and an FET25 is cut off, and the electric power is supplied to an output amplifier by discharging a capacitor 31. When the signal (vi) is lower than the voltage (ei), the output voltage is inverted again to repeat the above-mentioned operation. That is, the switch FET25 is turned on and off by a feedback system in a self-exciting way in response to the level of output quantity and while the maximum conduction time of the switch is suppressed by the circuit 45. As a result, the output quantity is kept at an equal level of the input voltage (ei).

Abstract: PURPOSE:To produce a graphic form having shadow in high quality by unifying the shadow with a graphic form when a graphic form having shadow is produced so that the graphic form forming efficiency is improved and the shadow attribute can be optionally selected. CONSTITUTION:The shadow attribute is first designated by an input device 530.

Abstract: PURPOSE:To efficiently perform a current constriction without generating the loss of light and to contrive to be able to drop an oscillation threshold value by a method wherein a current constricting layer is constituted of specified first and second current constricting layers. CONSTITUTION:A first conductivity type first current constricting layer 9 has a band gap which does not absorb light from an active layer 3. A first conductivity type second current constricting layer 10 has a band gap which absorbs the light from the active layer 3 and its aperture is formed larger than that of the layer 9. Accordingly, a current is constricted by the layer 9 to be injected in the active layer 3 and light, which luminesces in the active layer 3 by this injection and infiltrates into the layer 10, is absorbed by the layer 10. Thereby, the loss of light is not generated and furthermore, to increase the current is also eliminated and the oscillation threshold value can be easily dropped.
