Title: Voltage comparison circuit
Inventor: OKAYASU TOSHIYUKI
IPC: G01R19/165
Filed: 1993-03-22
Abstract: PURPOSE:To eliminate an influence due to the frequency dependence of a drain conductance (gd) by a method where drain-to-base voltages for a first field-effect transistor (FET) and a second FET are kept at definite values. CONSTITUTION:In a first FET Q1 and a second FET Q2, the side of each source is connected to a power supply -V, and the side of each drain is connected to a power supply +V. When an input signal Vin is given to FETs Q1, Q5 and a reference voltage Vr is given to FETs Q2, Q6 a minimum-value (increase) current flows to the FET Q1 and an increase (minimum value) current flows to the PET Q2 when Vin<Vr (Vin>Vr). Constant-current circuits I1, I2 are not turned off even at a minimum value and an increase portion flows to a constant- current circuit I3. FETs Q3, Q4 to which constant-voltage elements ZD1, ZD2 give a definite voltage are operated so as to keep a gate-to-Source voltage definite, and the FETs Q1, Q2 keep a drain voltage definite. As a result, while the drain-to-source voltage VGS is kept definite, only a current is increased or decreased by whether the signal Vin is high or low, a voltage change is caused in load resistances RD1, RD2, and terminals TO1, TO2 output a compared result. Consequently, a comparison error is not caused in an FET whose gd is provided with a frequency characteristic.

Title: Inspecting method for resistance wire strain gauge
Inventor: MATOBA YUJI
IPC: G01B3/06
Filed: 1985-03-28
Abstract: PURPOSE:To easily check whether or not a measurement of strain is taken accurately by connecting at least one intermediate lead wire to a halfway point of a resistance wire and thus sectioning the resistance value into plural resistance wires having the same resistance value, and measuring the quantity of strain induced on each resistance wire. CONSTITUTION:When the total resistance value between terminal lead wires 3A and 3B is denoted as 2R, the resistance value between the lead wire 3A and intermediate lead wire 3C and the resistance value between the lead wire 3B and lead wire 3C are R. If the lead wire 2 is strained, variation in the resistance value between the lead wires 3A and 3C and variation between the lead wire 3B and 3C become equal to each other as long as a wire strain gauge is normal. If however, the adhesive strength between the wire strain gauge and a body to be measured decreases or if the resistance wire 2 deteriorates, there is a difference in variation in resistance value generated. For the purpose, the quantity of strain between the lead wires 3A and 3C and the quantity of strain between the lead wires 3B and 3C are measured and compared with each other to check the resistance wire strain gauge.

Title: Paper feeder
IPC: B65H11/00
Filed: 1992-03-18
Abstract: PURPOSE:To prevent a failure of paper sheet feed while enabling a manual insertion paper sheet to be sent/energized sufficiently by means of a pickup roller when the paper sheet is fed by providing a gear mechanism to transmit a rotational motive power to a driven gear, and providing a fixing means to lock a rotary shaft and the driven gear within an allowable angle range so as to be capable of making relative turning motion. CONSTITUTION:When the tip of a manual feed paper sheet P being inserted from a paper sheet inserting part 15 butts the peripheral surface 22 of a pickup roller 21 in a standby condition, the pickup roller 21 is pushed by the paper sheet P, and is put in turning motion in the sending direction within an allowable angle range. Thereby, the manual feed paper sheet P is fed perfectly to the roller 21. When a driven gear 25 is rotated in the arrow direction through a gear mechanism 45 under this condition, a rotary shaft 24 is rotated in the sending direction through a twin fan shape groove part 35, a fixing pin 32 and so on, so that a paper sheet feed operation is carried out. Thereby, the manual feed paper sheet P is sent/energized sufficiently, and is sent out reliably from the pickup roller 21, so that a failure of paper sheet feed can be eliminated.

Title: Flaw detecting method of steel product
Inventor: ISHIKAWA HIDEYUKI
IPC: G01N29/14
Filed: 1979-05-19
Abstract: PURPOSE: To achieve the improvement in the accuracy of flaw detection and the improvement in production efficiency by mounting acoustoelectric transducers to the steel product and detecting the production of flaws based on the electric signals output by the acousto-electric transducers during surface hardening to the steel product.  
     CONSTITUTION: The gear GR mounted with the sensors 1aW1d comprising using acousto-electric transducers is put into a high-frequency hardening device and while it is being subjected to hardening, the circuits of the sensors 1aW1d and afterward are driven, whereby the flaw defection is accomplished. When hardening cracking occurred during the treatment, the elastic waves of a high level are produced and therefore the main amplifier output of the elastic waves taken into a main amplifier 6 through a channel selector 3 from the sensors 1aW1d exceeds the threshold level Th of a level discriminator 7, by which the plural pulse signals are output to a counter 8. The counter 8 counts these and when the count value reaches the set value, an alarm device 9 actuates to alarm the occurrence of hardening cracking.

Title: Liquid fuel burning device
Inventor: TOMITA HIDEO
IPC: F23D11/24
Filed: 1986-03-20
Abstract: PURPOSE:To achieve burning condition without generation of carbon monoxide and soot, prevent the temp. rise in nozzles, and stabilize the burning quantity by installing shielding plate near the upper part of the nozzles. CONSTITUTION:Fuel oil pressurized by an oil pump 65 in spouted from nozzles 61A, 61B and this atomized oil is mixed with air to start the so-called pressure type atomization burning by the electric discharge from an ignition electrode 22. Burnt gas colliding to an inner cylinder 52 descends along the cylinder 52 and forms a circulating stream flowing in a vaporizing region 70 from a communication holes 5 and keeps the region 70 at a high temp. This circulating stream causes a fire flame to descend and a descending fire flame is generated. At the neighborhood around the nozzles 61A, 61B where an isolation plate 60 is installed, the circulating stream is not formed and also a descending fire flame is not generated. Therefore, the oil drop burning caused by the descending fire flame serving as an ignition source is not generated and excellent burning condition without generation of carbon monoxide and soot is achieved. Temp. rise in the nozzles 61A, 61B is prevented.

A pulse width per gradation in such a case becomes 12ns, and it is enlarged six times compared to a pulse width 2n per gradation when zigzag scanning is not executed. Then, the displayed image with high gradient can be obtained.

The object to be dehydrated lying to the left from center line L of rotary shaft  5 during the process of rising is sufficiently dehydrated and filtered by water-removing basket 4,  and the object to be dehydrated lying to the right of center line L is separated from water-removing basket 4, and thereby preventing the clogging of water-removing basket 4. Moreover, by the  rotation of water-removing basket 4, dehydration is operated efficiently on the object by replacing  the dehydrated and filter portion and the separated portion alternately.
