Title: Heat exchanger
Inventor: INOUE SHIRO
IPC: F28D7/16
Filed: 1984-10-19
Abstract: PURPOSE:To permit to clean heat transfer tubes easily by a method wherein heat medium fluid is sealed into the trunk of the shell-and-tube type heat exchanger and high-temperature fluid is flowed through the lower part of the group of heat transfer tubes while low- temperature fluid is flowed through the upper part of the group of the same. CONSTITUTION:The heat medium fluid A is sealed into a sealed chamber 16. The sealing amount of the heat medium fluid is in a degree that the interface between gas and liquid upon operating arrives at an intermediate position between the group 14 of upper heat transfer tube and the group 14' of lower heat transfer tubes. The high-temperature fluid B is flowed through the group 14' of lower heat transfer tubes while the low-temperature fluid C is flowed through the group 14 of upper heat transfer tubes. The heat of the high-temperature fluid passes through the wall surface of the lower heat transfer tubes 13 and is transmitted to the heat medium fluid A. Then, the heat medium is boiled and evaporated immediately and the vapor ascends through the sealed chamber 16 to transmit the heat to the low-temperature fluid flowing through the upper heat transfer tubes 13, simultaneously, the vapor is condensed and becomes liquid drops thereby dropping through the sealed chamber 16. According to such cycle of the heat medium fluid, heat may be transmitted from the high-temperature fluid, flowing through the lower heat transfer tube group 14', to the low-temperature fluid, flowing through the group 14 of upper heat transfer tubes.

Abstract: In a process for phosphating iron and steel surfaces according to the low-zinc technology, a nitrite-free aqueous acidic phosphating solution of 30 to 65 DEG C is used which contains     0.4 to 1.7 g/l of Zn   7 to 25 g/l of P2O5   2 to 30 g/l of NO3 and in which the weight ratio of free P2O5 to total P2O5 is adjusted to a value in the range from 0.04 to 0.20. H2O2 or alkali metal perborate is added to the phosphating solution in an amount such that - in the incorporated state - its maximum peroxide concentration is 17 mg/l, preferably 8 mg/l (calculated as H2O2), or its maximum Fe(II) concentration is 60 mg/l, preferably 30 mg/l (calculated as Fe). It is particularly advantageous to control the addition of H2O2 and/or alkali metal perborate according to the electrochemical potential determined with a redox electrode. The phosphating solution may additionally contain Mn, Ni, Co, Mg and/or Ca or fluoroborate, fluorosilicate and/or fluoride. The process can be used in particular for the preparation of metal surfaces for coating. <IMAGE>

Title: Drive circuit for printer
Inventor: MANFUREETO GURIYUNAA
IPC: H01F7/18
Filed: 1982-12-16
Abstract: The drive circuit for an electromagnetic actuator for the impact element in a printer includes a series circuit of a drive transistor and of a switching transistor there being a reference resistor interposed which together with a Zener diode serves as a current limiter for the current through the drive transistor and the electromagnetic element. The two transistors are controlled in that each of the base electrodes is serially connected to the emitter collector path of a control transistor and the two control transistors in turn are connected to monostable multivibrators which are triggered concurrently but furnish pulses of different duration such that the switching transistor is turned off before the drive transistor. The current limiting permits utilization of residual electromagnetic energy from the preceding actuation pulse without incurring undue losses.

Title: Oscillation type dc igniter
Inventor: ISHIKAWA MICHIO
IPC: F02P15/10
Filed: 1986-09-19
Abstract: PURPOSE:To aim at an increase in ignition power, by installing a rectifier at the secondary high-tension side of an ignition coil, in case of an igniter which secures a high voltage by oscillation of the ignition coil using a closed iron core of a ferrite core or the like and a semiconductor. CONSTITUTION:When a point p is closed, power flows into an emitter of a transistor Q1, a base, a resistor R2 and a body for conduction, adding voltage to a transistor Q2 for conduction, whereby oscillation is produced among a transistor Q3, a coil, a condenser C1 and a resistor R3, thus a high voltage is generated in a secondary side coil of a transformer T. This high voltage is rectified by a rectifier D1 and impressed on a distributor. Here, a closed iron core of a ferrite core or the like is used for the transformer T. Thus, magnetoresistance force is small, ignition power in a secondary high voltage is enlargeable, a startup also becomes so sharp, and it is made into a direct current so that there is almost nothing of a floating capacity loss, thus a stable secondary high voltage is generated irrespective of aneing speed.

Title: Coil bobbin
Inventor: YOSHIDA SHIGERU
IPC: H01F27/32
Filed: 1989-08-28
Abstract: PURPOSE:To obtain a coil bobbin in which a winding collapse is not caused even at a high-speed winding operation by a method wherein at least two kinds of tapers whose angles are opposite with reference to an axial direction of a winding are formed so that a length of a circumference face of a winding part can be set to be nearly equal in any position in the axial direction. CONSTITUTION:A coil bobbin 1 is formed in such a way that a peripheral edge of a winding part 2 is set to be a tape [dimension (a)< dimension (c)] in a state as viewed from a plane and that the peripheral edge of the winding part is set to be a taper [dimension (b)> dimension (d)] as viewed from the front. That is to say, two kinds of tapers whose angles are opposite with reference to the axial direction of a winding are formed at the winding part 2 of the coil bobbing 1. Since the angles os the tapers are set so as to be a dimension 2a+2b  a dimension 2c+2d, a length in a winding direction at a circumference face of the winding part 2 is nearly equal in any position in the axial direction. Consequently, a winding collapse which was a problem in conventional winding operations of a coil is not caused; a high-speed winding operation can be executed.

Abstract: PURPOSE:To simplify the constitution of a circuit by delaying a video signal read out from a memory means corresponding to a phase difference and mixing a color signal where a luminance signal is removed with the luminance signal where the color signal is removed from the video signal before a delay. CONSTITUTION:When a read timing T2 is inputted in a latch circuit 12, phase information read out from a memory 13 is inputted in a phase difference detection circuit 14 and the phase difference (x) is detected. At the same time the video signal read out from the memory 13 is inputted in a delay circuit 15 and it is made to be delayed by the phase difference (x). And the video signal outputted from the delay circuit 15 is converted into an analog value and the luminance signal components of the signal is removed by a band-pass filter 18 to be inputted in a mixing circuit 20. The video signal read out from the memory 13 is converted into the analog value and the color signal components of the signal is removed by a band-elimination filter 19 to be inputted in the mixing circuit 20. Thus the screen having a favorable color link on one screen can be composed.

Title: Fuel injection control unit for engine
Inventor: NAKAMURA NORIHIRO
IPC: F02P5/152
Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To optimize fuel amount to be increased according to an octane number of used fuel so as to prevent a damage to parts caused by overheating in an exhaust system by lowering an exhaust temperature. SOLUTION: In this system, it is judged whether or not a coefficient of fuel amount to be increased for lowering exhaust temperature KRICH is 1.0 or more (S102). When judged that KRICH is 1.0 or more, that is, in a high exhaust temperature range, a difference between a real final spark timing SPKreal and a spark timing for regular gasoline STD is calculated as an advancing angle amount X (S104). A fuel reduction amount coefficient KGEN is set with reference to a table in which the advancing angle amount X serves as a parameter (S105).  A final fuel injection pulse width Ti is set by correcting the coefficient of fuel amount to be increased for lowering exhaust temperature KRICH with the fuel reduction amount coefficient KGEN (S106, S107) Accordingly, a fuel amount to be increased is optimized by the coefficient of fuel amount to be increased for lowering exhaust temperature KRICH according to an octane number of the fuel actually used. Therefore, protection for a catalyst or the like is enabled by preventing overheat of the exhaust system reliably by not causing excessive or insufficient fuel increase.
