Title: Electron gun structure for color image receiving tube
Inventor: TAKAHASHI YOSHIAKI
IPC: H01J29/50
Filed: 1988-03-16
Abstract: PURPOSE:To provide excellent resolution by providing a sideways longer opening in horizontal direction around an opening on the converging electrode side of a control electrode and an accelerator electrode. CONSTITUTION:On the converging electrode side of a G1 electrode (control electrode) 41 and a G2 electrode (accelerator electrode) d2, sideways longer openings 5b, 6b are provided in the horizontal direction around openings 41b, 42b in these electrodes so as to generate an axially asymmetrical electric field about axis. Such a constitution shall be alike in the electron gun portions on both sides of an in-line type electron gun, i.e. in other openings 41a, 41c in the G1 electrode 41 and G2 electrode 42. Whether the beam current of electron beam is greater or smaller, the electron beam is properly distorted by this axially asymmetrical electric field about axis sideways longer in the horizontal direction and focused and projected on a fluorescent screen while properly combined with the action of irregular magnetic field to ensure that a good beam spot is formed on the whole screen. This prevents deterioration of the resolution of color image receiving tube.

Title: Method for blowing gas into molten metal
Inventor: OGAWA YUJI
IPC: C21C5/52
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To extend the variable range of gas flow rate by preheating the gas in the case of increasing the gas blowing rate so as to keep a sound mushroom. SOLUTION: In this method, gas is blown after preheating in the case of blowing the gas so that an apparent line flow speed exceeds 300Nm/sec at the tip part of a blowing nozzle. This is based on the information that, at the time of flowing the gas at higher speed, mushroom is grown in an excess degree and the gas flow passage tends to clog, and at the time of lowering the flow rate of the gas such as to 200-400 Nm/sec apparent line flow speed, the sound mushroom is formed and the service life of a tuyere is hroloneed. Even in the case the gas flow rate becomes <200Nm/sec or> 400Nm/sec apparent line flow speed, the variable range of the gas flow rate can be extended while keeping the formation of the sound mushroom by controlling the gas temp. so that the cooling capacity becomes almost constant.

Title: Biological treating apparatus for waste water in a low concentration
Inventor: SHIMIZU KOICHI
IPC: C02F3/28
Filed: 1988-03-15
Abstract: PURPOSE:To enhance the efficiency of contact between anaerobic microorgan- isms and waste water, by providing a fixed bed having supports to which the anaerobic microorganisms are liable to attach and which are placed randomly therein in a reaction tank for receiving the waste water through its bottom and outflowing the purified water through it top. CONSTITUTION:The waste water 1 being flowed upstream into a reaction tank 2 by a raw water supply pump 3 is sent from the bottom to the top thereof while in contact with the anaerobic microorganisms attached to a fixed bed 4 so as to undergo the decomposition of the organic substances. The water 6 thus purified is discharged out of a treatment device from the upper part of the reaction tank 2 through a siphon 5. The fixed bed, with the supports 8 provided randomly therein, produces a turbulant flow against the water stream in the reaction tank 2 to prevent the disruption of the water flow therein, thereby enhancing the efficiency of contact between the waste water 1 and the anaerobic microorganisms. Furthermore, the fixed bed 4 exerts a filtering effect to thereby prevent the outflowing of the anaerobic microorganisms.

Title: Magnetic bubble memory element
Inventor: KONDOU HIRONORI
IPC: G11C11/14
Filed: 1982-04-14
Abstract: PURPOSE:To increase the current margin, by setting the rising or falling time when the current flowed to a conductor reaches the designated 90% value at the prescribed value. CONSTITUTION:The rising time when the current flowed to a conductor reaches the designated 90% value is set at >=1/8 rotary magnetic field period equivalent to 45 degrees of the phase difference between rotary magnetic fields at the maximum and minimum values of a conductor current. As a result, the difference between the maximum and minimum currents is increased compared with a case where a square wave current is used. Thus the current margin is also increased. The same effect is obtained by setting the falling time in the same way.

Title: Facsimile broadcast receiver
Inventor: NOHARA SATOSHI
IPC: H04N7/08
Filed: 1991-03-04
Abstract: PURPOSE:To attain the classification, retrieval and confirmation of a picture signal through the use of reception information by correspondingly processing the picture signal and the reception information relating to a received broadcast at a picture signal processing means such as a printer, monitor and a memory. CONSTITUTION:When a reception reservation time comes, a reception signal is demodulated and a picture is generated and a picture signal is obtained from a picture generating section 3. Simultaneously, a reception information generating means generates reception information based on reception reservation information. A system controller 7 gives a received picture signal by one page to a picture memory 6 from the picture generating section 3 and gives the reception information thereto, in which the reception information is stored as a header of the picture signal. In the case of implementing soft or hard copy, the picture signal and the reception information are fed from the picture generating section 3 to a monitor 4 or a printer 5 to display the reception information onto the upper part of the picture. Thus, the classification, retrieval and confirmation of the picture signal are implemented by utilizing the reception information to improve the utility.

Title: Constant-voltage circuit
Inventor: KAJIWARA AKIHIRO
IPC: G05F1/618
Filed: 1983-04-08
Abstract: PURPOSE:To supply a relatively large electric current without using any large scale transistor and without causing no voltage variation in a low-impedance load, by connecting loads with each other in series. CONSTITUTION:Loads L1 and L2 are connected with each other in series and the output line of a constant-voltage circuit is connected between the loads L1 and L2. The constant-voltage circuit is formed in such a way that the base and emitter of a reverse conducting type transistor Q1 are connected with the base and emitter of another reverse conducting type transistor Q2, respectively, and their common base and common emitter are connected with a Zener diode ZD and the outut line, respectively. Moreover, collectors of each transistor Q1 and Q2 are connected with a power source through resistances R1 and R3, respectively. Since an electric current equal to the difference between an electric current I1 flowing to the load L1 and another electric current I2 flowing to the load L2 flows to the constant-voltage circuit, the difference electric current becomes smaller and, therefore, the voltage variation becomes smaller, even though the values of the electric currents I1 and I2 are both large.
