Title: Shaft sealing apparatus
Inventor: FUKUSHIMA YASUO
IPC: F16J15/40
Filed: 1981-09-11
Abstract: PURPOSE:To reduce the amount of drain oil and to thereby lower the running cost, by detecting the level of oil in a drain pot in which drain oil is once collected, and actuating an oil pressure control valve in a shaft sealing oil circulating line by applying the output signal of an oil level detector to a differential pressure controller. CONSTITUTION:In case that the amount of drain oil from a shaft sealing section 11 is reduced, the level of oil in a drain pot 18 is lowered. Resultantly, the level of output signal of an oil level detector 19 is also lowered, so that a low-level detector switch 20a is set into operation. By the operation of the detector switch 20a, a selector switch 17 is shifted and a differential pressure controller 15 is actuated by the output signal of the oil level detector 19 to open an oil pressure control valve 14 and to thereby increase the amount of shaft sealing oil supplied from an oil supply passage 12. Thus, the amount of drain oil can be controlled to a proper level. In case that the amount of drain oil is increased, on the other hand, the amount of shaft sealing oil to be supplied is reduced by way of reverse control. By thus controlling the amount of shaft sealing oil, it is enabled to lower the running cost and to prevent burn-out of seal rings.

Abstract: PROBLEM TO BE SOLVED: To print on parts to be printed of various forms by controlling an output data provided from a data storage part to output to a position based on positional information provided from a position sense part, and printing in accordance with a control signal of a printing control part. SOLUTION: When a user moves a main frame 50 with pressing a print button 40 manually, a rotary gear 36 of a sense part 33 and a linear gear 31 of a base frame 32 are meshed with each other and moved rotating along a guide groove 41. A rotating force of the rotary gear 36 is transmitted to an encoder 37 via a shaft 38, so that the encoder 37 rotates by an amount equal to the rotating force. The rotation amount of the encoder 37 is detected by an infrared sensor 39 and transmitted to a printing control part. The printing control part supplies an injection signal of an information in a data storage part through an ink cartridge 34 based on a positional information of a sense part provided from the sensor 39, thereby executing an ink jet operation.

Filed: 1986-06-18
Abstract: PURPOSE:To keep a printed circuit board itself from causing natural oscillation at a vibration test thereof, by performing a point pressing by an independent pressing force at several points arranged at fixed intervals along all four sides of the printed circuit board. CONSTITUTION:Four rotating shaft 12 which are driven to rotate through a link of a gear 18 using one air cylinder 17 are provided on the circumference of a printed circuit board 1 and pressing elements 10 each having a spring 13 for pressing the printed circuit board 1 are arranged on each of the rotating shafts 12 at fixed intervals. When the rotating shaft 12 turn and stops at respective fixed positions, all the pressing elements 10 press the printed circuit board 1 at points independently by a spring force. Thus, as pressing forces of the pressing elements 10 are independent of one another, there generate no clearance between the printed circuit board 1 and the pressing elements 10 regardless any gap a' between the printed circuit board 1 and the sponge 9, thereby keeping the printed circuit board 1 from developing natural oscillation.

Title: Image recorder
Inventor: SUZUKI AKIO
IPC: H04N1/00
Filed: 1990-05-30
Abstract: PURPOSE:To obtain a uniformly beautiful image having no irregularity irrespective of density of a copy image by a method wherein a read means which reads the copy image and a determination means which determines a recording density level of a test image for obtaining an irregularity-correcting data according to a read result of the copy image by this read means, are established. CONSTITUTION:A signal 103 for which image processing is performed is so converted as to correct irregularity of a recording head with an irregularity- correcting table ROM 104. An irregularity correcting RAM 117 stores a selective signal of a correction straight line necessary for correcting irregularity of each nozzle. That is, it stores 256 nozzle contents of an irregularity signal, and outputs the irregularity correction signal 118 in synchronization with an image signal to be inputted. By performing such process, a dot by a nozzle of a thick density part of the recording head lowers a printing duty, and a dot by a nozzle of a thin density part raises the printing duty reversely. Consequently, irregularity in density of the recording head is corrected, and a uniform image is obtained.

Filed: 1994-06-24
Abstract: PURPOSE:To produce a surface-treated steel sheet excellent in brazability and heat resistance by forming a mixed oxide layer of Al oxide and Mg oxide on the space of a steel sheet and an Ni-Cr brazable film. CONSTITUTION:On the surface of a steel sheet, a mixed oxide layer with 0.01 to 10mum thickness contg. At oxide and Mg oxide and in which the average content of the Al oxide is regulated to 10 to 90wt.% is formed. On the surface of this mixed oxide layer, a brazable film with 20mum thickness constituted of, by weight, 5 to 40% Cr, 1 to 20% B and/or Si, and the balance Ni is formed. This alloy film can be formed by plating, particularly by dry plating. The mixed oxide layer has an effect of suppressing the mutual diffusion between Ni in the brazing filler metal and Fe in the base material at the time of the heating and has a thermal expansion coefficient close to that of the steel sheet, and peeling caused by the thermal expansion of the steel sheet does not generate. Furthermore, at the time of the heating, the base material components and brazing filler metal components exuded from cracks and gaps along the grain boundaries are mixed and firmly joined.

Title: Logic level conversion circuit
Inventor: KAMURO SETSUSHI
IPC: H03K19/0185
Filed: 1990-05-31
Abstract: PURPOSE:To prevent a through-current from flowing from a power source to earth by controlling an output voltage applied to a gate electrode so that one transistor (TR) is interrupted while the other TR is conductive. CONSTITUTION:When the signal voltage of logic '0' is applied to a 1st inverter 34, a voltage at an output terminal goes to logic '1' and since the voltage at the output terminal is applied to the gate of one TR 35 of a 2nd inverter 40, the one TR 35 is conductive. Since the voltage of logic '0' is applied also to control means 37, 39, the control means 37,39 interrupt the other TR 38 of the 2nd inverter 40. Conversely, when the signal voltage of logic '1' is applied to the 1st inverter 34, the TR 35 is interrupted and the signal voltage of logic '1' is applied to the control means 37, 39, which make the TR 38 of the 2nd inverter 40 conductive. Thus, no through-current flows to the 2nd inverter.
