Title: Manufacture of rapid-start fluorescent lamp
Inventor: NARITA JIROU
IPC: H01J61/54
Filed: 1983-12-23
Abstract: PURPOSE:To obtain a rapid-start fluorescent lamp having a stable starting characteristic by forming an antimony oxide film on the inner surface of the glass tube and forming a tin oxide film containing a small quantity of antimony on said antimony oxide film in an oxidizing atmosphere. CONSTITUTION:A glass tube for a fluorescent lamp is heated in a stream of nitrogen to form an antimony oxide film (Antimony oxide is a dielectric substance.) on the inner surface of the tube. Next, the thus obtained body is further heated in an oxidizing atmosphere to form a tin oxide film containing a small quantity of antimony on the antimony oxide film. As a result, a transparent conductive film having a low resistance is formed even when the concentration of tin in the film is decreased. An insulating protective film of minute alumina particles or similar material is formed on the transparent film as necessary. By the means mentioned above, an energy-saving rapid-start fluorescent lamp which has a good starting characteristic and in which yellow sports are minimally formed is obtained.

Title: Power amplifier
Inventor: OIKAWA HIROO
IPC: H03F3/68
Filed: 1985-10-30
Abstract: PURPOSE:To save number of DC blocking capacitors into one by connecting one input terminal of the 2st and 2nd speaker loads to an output terminal of the 1st and 2nd power amplifier sections whose output terminal DC potential is equal to each other, connecting the other input terminal of each speaker and connecting a capacitor between the connected part and ground. CONSTITUTION:The 1st and 2nd power amplifier sections 2, 4 are conventional power amplifiers provided with complementary output stages 10, 11 and the DC potential at the output terminal is nearly 1/2Vcc. Thus, the DC potential of each output stage gives no effect on the current flowing from the output terminal of the 1st power amplifier section 2 to the output terminal of the 2nd power section 4 through the 1st speaker load 6 and the 2nd speaker load 8. Similarly, the converse flowing gives the same effect. The connecting point between the 1st speaker load 6 and the 2nd speaker load 8 is grounded in terms of AC and only the AC signal is driven by the speaker loads 6, 8.

Filed: 1983-12-23
Abstract: PURPOSE:To attain weight reduction and to read accurately information by providing an optical system which consists of an aspherical projection lens and a lens barrel for supporting it, and a relative position detecting means which detects the relative position between an information track and a spot of light. CONSTITUTION:When the spot of light shifts from a read point in the center of the information track in three dimensioal, direction a detector 8 connected to a photodetector 7 detects which direction the spot of light shifts in. The output of the detector is supplied to an information detection head 6' which has the aspherical projection lens 101 fitted to the lens barrel 102 to control the position of the projection lens supported movably in the three dimensional direction according to the detected shift in light spot position. Consequently, the shift from the optical axis of the light spot in a plane crossing the optical axis of the light spot at right angles corresponds to the reduction magnification of the projection lens with the amount of movement of the lens and the light spot is positioned accurately at one point on an information track to perform focusing.

Title: Detecting apparatus of flow rate of fuel gas
Inventor: OSADA KIYOSHI
IPC: G01F3/20
Filed: 1991-09-24
Abstract: PURPOSE:To obtain an apparatus which can detect the flow rate of a fuel gas generated in a fuel tank in a simple constitution. CONSTITUTION:A fuel gas is introduced into a cylinder part 9 through a suction pipe 6. When the pressure in the cylinder part 9 is raised, a diaphragm 4 is moved upward and consequently the cylinder part 9 communicates with a diaphragm chamber 10. At this time, a magnet 16 is moved to the front of a magnetic field sensor 14. Therefore, the magnetic field sensor 14 generates a high level signal. When the fuel gas is discharged from a discharge pipe 7 and the pressure of the diaphragm chamber 10 is lowered, the diaphragm 4 is moved downward, with closing a communication hole 19. The pressure when the communication hole is closed is Lower than that when the communication hole is opened because the pressure receiving area of the diaphragm 4 is widened in the former case. Therefore, the hysteresis is present between the valve opening pressure and the valve closing pressure. When the diaphragm 4 is moved down, a magnet 17 is moved to the front of the magnetic field sensor 14 and accordingly the signal is changed to a low level signal. The flow rate of the fuel gas can be calculated based on the hysteresis by detecting the time while the high level signal is generated.

Abstract: PURPOSE:To shorten the overall length of a valve piston, by installing an outlet valve in the valve piston receiving pedal operating force as well as installing an inlet valve in the said outlet valve in parallel, while operating the inlet valve via an interlock member at a time when the valve piston goes forward. CONSTITUTION:An outlet valve 30 is installed in a tip end of a valve piston 38, while the said valve 30 controls interconnection and interception between an output hydraulic chamber 25 and an oil trank 2. An inlet valve 29 is installed in a booster cylinder 20 in parallel with the outlet valve 30.

That is to say, when the valve piston 38 is in nonoperational, the inlet valve 29 is closed but the outlet valve 30 is opened whereby a booster S is made to come into a state of being nonoperational. When the valve piston 38 goes forward, the outlet valve 30 closes and simultaneously an interlock member 47 installed in the valve piston 38 advances forward whereby the inlet valve 29 opens via an actuating rod 35. Therefore, pressure in these hydraulic pressure sources 27 and 28 is fed to the output hydraulic chamber 25 so that the booster S operates.
