Title: Constant current circuit
Inventor: KANESU NORIYUKI
IPC: G05F1/56
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a constant current circuit which operates stably and can supply a constant current in accordance with the control signal voltage even when the input/output characteristic of a control transister or a wiring resistance varies. SOLUTION: This circuit consists of the modules 10a-10j of the same constitution, and a constant current is supplied to a load terminal 2 in accordance with the control signal voltage supplied to a control input terminal 1. In each of the modules 10a-10j, the drain of an Nch type MOS transistor Tr1 is connected to an output terminal 12 and an operational amplifier 15 is connected to the gate of the Tr1. A source current I1a is detected by a current detection resistance R1 and a differential amplifier 16, controlled by the negative feedback action of the amplifier 15 and not affected by a wiring resistance R2a. The negative feedback is carried out on each module to keep the constant control characteristic of the module. Therefore the current I1a has no variance despite the variance in the input/output characteristic of the Tr1.  Thus, the Tr1 never exceeds the highest bonding temperature nor the highest drain current standard.

Title: Fuel injection valve controller for compression ignition type internal combustion engine
Inventor: SASAYAMA TAKAO
IPC: F02D41/34
Filed: 1978-05-12
Abstract: PURPOSE: To improve response by providing a pulse generator detecting engine feed- air speed and engine speed both as digital amounts.  
     CONSTITUTION: An engine speed detecting pulse generator 1 outputs pulse sequentially, and when output of an engine feed-air speed detecting pulse generator 2 tends to lower level, an up-down counter 13 begins to count down counts. On the other hand, output of a ring counter 3 becomes set input for a set-reset type flip flop 14 through an invertor 11. Accordingly, the signal of beginning down count is given as set input for the set-reset type flip flop 14 and set the flip flop 14, thereby, the Q output thereof is increased into high level and put a transister 15 driven on the base of the Q output "ON" condition, which puts a fuel injection valve 16 into operation to inject fuel for the engine.

Title: Interlocking device of breaker for wiring in switchboard
Inventor: MASUMOTO HIDEYUKI
IPC: H02B1/14
Filed: 1988-03-09
Abstract: PURPOSE:To allow each breaker to be interlocked, by moving an engaged member with a locking member and by transmitting its displacement to the other engaged member to read it from the position where the locking member is brought into contact. CONSTITUTION:When a knob 24 of the 1st handle operation device 19 is operated to the ON position, the 1st locking member 33 moves the 1st engaged member 40 by designated quantity, which will stop before the 1st locking member 33 reaches the locking position. The knob 24 is operated as it is, the 1st breaker 17 for wiring is turned ON and a door 13 is locked. On the other hand, the movement displacement of the 1st engaged member 40 is transmitted to the 2nd engaged member 41 by an interlocking member 42, so that the 2nd locking member 37 is caused to retreat from the position where it is brought into contact. Under this condition when a knob 36 of the 2nd handle operation device 20 is operated in the ON direction, the 2nd locking member 37 is interlockingly acted to lock the knob 36. On that account, when the 1st breaker 17 for wiring is turned ON, the 2nd breaker 18 for wiring cannot be turned ON.

Title: Control method for roll eccentricity of rolling mill
Inventor: HOSHINO IKUYA
IPC: B21B37/66
Filed: 1986-03-13
Abstract: PURPOSE:To perform the highly accurate plate thickness adjustment by compensating a rolling load varying component caused by a roll eccentricity by adjusting a balancing force for backup roll balance. CONSTITUTION:A loading force variation DELTAPLC detected by a load cell is sent to a roll eccentricity component analyzing unit 1, which uses a band-pass filter in which pass frequencies are changed to backup roll rotation frequencies. The unit 1 extracts a roll eccentricity component DELTAPE from load signals by the load cell. The component DELTAPE is sent to a balancing force adjuster 2, which adjusts so that a balancing force variation equals to the DELTAPE.

Abstract: PURPOSE:To display the whole contents of a line on a screen by dividing characters in one line into plural lines at the time of deciding that the number of characters in a stored line exceeds the number of display digital of each line of a display means and outputting respective divided lines. CONSTITUTION:When plural character strings are inputted from an input part 15, these inputs are stored in a RAM 14 in each line through a CPU 11. The CPU 11 decides whether the number of characters in each line stored in the RAM 14 exceeds the number of display digital of each line on a display part 16 having the prescribed number of display digits or not. At the time of deciding the number of characters does not exceed the number of display digits, the data stored in the RAM 14 are directly outputted on the display part 16, which displays characters or the like based upon the data. At the time of deciding the the number of characters in one line stored in the RAM 14 exceeds the number of display digits of each line on the display part 16, characters in one line stored in the RAM 14 are divided into plural lines and the data of the divided lines are outputted to the display part 16. The display part 16 displays the character string inputted over the number of display digits of the display part 16 on the same display screen by plural lines.

Title: Method for heating corrosive liquid, etc.
Inventor: IGARASHI SHIGEO
IPC: F28C3/06
Filed: 1994-03-25
Abstract: PURPOSE:To achieve a marked improvement in thermal conductivity, good resistance to chemicals, and other useful effects by passing saturated steam, etc., through a tubular vessel consisting of sintered silicon carbide which forms an aggregation of pores of less than a specific size to heat a corrosive liquid through the pores. CONSTITUTION:Inside a tank 1 which holds a corrosive liquid 4 such as an acid a tubular vessel 2 is placed, which consists of sintered silicon carbide forming an aggregation of numerous pores 5 of less than 10mum and whose surface appears black. By passing a stream of saturated steam or hot air through the inside of the tubular vessel 2 the corrosive liquid 4 inside the tank 1 is heated through the pores 5. Since the whole of the tubular vessel 2 is made up of numerous projections and depressions formed by numerous pores 5, the area for heat exchange is enlarged and the heat load density is multiplied. Therefore, the synergy of this effect with the excellent thermal conductivity of silicon carbide itself enables efficiently heating the corrosive liquid 4 in the tank 1.
