Abstract: PURPOSE:To provide a high-pressure sodium lamp having a stable luminous spot of discharge and excellent in performance characteristics, by melt-spraying aluminum oxide onto the portion of an electrode rod except its tip portion and onto the portion of an electroconductive member which is exposed to the interior of a luminous tube. CONSTITUTION:A luminous tube 2 is made of polycrystalline alumina or single crystal of alumina. A metal such as sodium and mercury to become a buffer gas, and a starting rare gas, which is neon alone or a mixture of neon and argon or the like, are sealed in the tube 2. The interior of an outer tube 1 is kept in a vacuum by using a getter. An electrode 6 comprises a rod 7 and a coil 8. Al2O3 10 is melt-sprayed at a thickness of 10mu or more onto the portion of the electrode 6 except an area of 1mm., for example, from the tip of the rod 7, and onto the portion of an electroconductive member 9 which is exposed to the interior of the luminous tube 2. As a result, electrons are emitted only from the tip portion of the electrode 6 so that the luminous spot of discharge is stabilized early and excellent performance characteristics are achieved.

Title: Dc compound motor
Inventor: TSUJIMOTO SHIZUO
IPC: H02P7/06
Filed: 1977-12-02
Abstract: PURPOSE: To eliminate unbalance of flux generated by shunt winding divisions with such a construction that a bridge is constituted by coils of the same impedance even at the time of sudden change of the overhead line voltage.  
     CONSTITUTION: A DC motor 1 has a shunt winding consisting of divisions 4A and 4B, which form a bridge together with external windings 12 having the same impedance as that of each shunt winding division. Of the terminals of this bridge, two opposing terminals are connected to a shunt circuit, and the other terminals are connected to an exciting circuit of a rectifying circuit 9. Thus, when the frequency is reduced to be lower than a reference frequency with reduction of the voltage on the overhead line 11, a thyristor 91 of the rectifying circuit 9 is fired to cause exciting current I e  to flow in the opposite direction to the shunt current I f  through the shunt winding divisions 4A and 4B. When the overhead line voltage 11 is increased, a thyristor 92 is fired to cause the exciting current I e  to flow in the same direction as the shunt current I f  through the shunt windings 4A and 4B.

Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by preventing a transfer material electrifying means (paper electrifier) from acting when an image is formed only on the front surface of transfer material. SOLUTION: When a double-sided image forming mode is selected, the paper electrifier 150 is actuated by a DC constant-current power source E1, and double- sided image forming process is executed by a double-sided image forming program P1, so that the color toner image of a back surface image is transferred on a toner image receiving body 14a and the color toner image of the front surface image is formed on a photoreceptor drum 10. When a back-surface image forming mode is selected, the electrifier 150 is actuated by the power source E1 and a back-surface image forming process for one surface is executed by a back surface image forming program P2, so that the color toner image of the back surface image is transferred on the receiving body 14a.  When a front surface image forming mode is selected, the toner image does not exist on the receiving body 14a, so that paper electrification is not performed, and the actuation for the electrifier 150 by the power source E1 is not performed.

Filed: 1979-11-07
Abstract: PURPOSE: To perform setting of proper developing bias voltage by disposing members which detect the colors and densities of the ground colors of an original to a photodetecting part.  
     CONSTITUTION: The output signals of level discriminating circuits 7A, 7B respectively emit high levels to the terminals L, H' alone and emit low levels to all the other terminals M, H, etc.; therefore, these signals are inputted via latching circuits 8AW8F to selecting logic circuits 9, so that only the output of the logic circuit 9C is made the signal of a high level and the outputs of all the other logic circuits are made the signals of a low level. Hence, the combinations of the output signals of the circuits 9 corresponding to the kinds and varying densities of the colors of the original ground colors placed on an original platen are obtained from a series of operations. ON and off of switching transistors 10AW10I of a developing bias voltage selecting circuit 10 are accomplished by these combined output signals. Thereby, proper developing bias voltage can be set.

Title: Display method for request specification component element
Inventor: HIRASAWA KEIICHI
IPC: G06F9/06
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To change more easily a request specification by merging and dividing the characters when a system engineer acquires the request specification of a development object from a customer. SOLUTION: A 'preparation' character 3002 means a node character where a character is merged with a node character. An operator selects a 'character hierarchy display' command out of a command menu of a character definition editor. The character information and the node character information are successively acquired from the character definition information to generate the hierarchy display information. The characters are arranged again in a character display area 301 based on the generated hierarchy display information, and the lines 3101 to 3103 are drawn to show the hierarchies among characters. Thus, the relations among characters can be visually grasped while a request specification is acquired.

Filed: 1983-08-10
Abstract: PURPOSE:To decrease an input power and also to attain a high-frequency circuit by using an MOSFET as an input side transistor (TR) and using a bipolar electrostatic induction TR as an output side TR. CONSTITUTION:The MOSFETQ4 having a smaller input current is used as the input side TR and also the bipolar mode electrostatic induction TRQ3 having a small storage time is used as the output side TR.
