Title: Fluff tester
Inventor: TSUTSUI SHINICHI
IPC: D02J1/00
Filed: 1993-07-30
Abstract: PURPOSE:To provide a fluff tester enabling fluffs of yarns traveling in high speed to be tested accurately and stably. CONSTITUTION:This fluff tester is equipped with (A) a projector 1 to project light beams on a traveling yarn 5, (B) a light receiver 2 to receive light beams changed in light level due to yarn fluffs, (C) a transducer 8 to transduce the light level received by the receiver 2 into voltage output, (D) an A/D transducer 9 to transduce the voltage output into digital output and (E) an operator 10 to discriminate the above digital output from noise and determine the digital output change for a specified time as fluffs to calculate the amount of fluffs. In this fluff tester, the projector and the light receiver are so arranged so that the light beams are parallel with the traveling yarn and such an air nozzle 6 as to supply rectified air of uniform flow to the traveling yarn throughout the fluff testing interval is also set up. This tester enables accurate fluff test for yarns traveling in high speed and improves fluff detection accuracy, resulting in determining the cause of developing fluffs on yarns traveling in high speed on looms or in spinning processes and in reducing fluff test time.

Title: Thermal printer
Inventor: TANIGUCHI JUN
IPC: B41J19/00
Filed: 1995-07-26
Abstract: PURPOSE: To make a thermal printer compact and inexpensive, by providing a driving force-transmitting means for transmitting a driving force of a driving motor to a roller-driving shaft only when a thermal head goes beyond a printable range and controlling a moving action of a carriage and a driving action of a transfer roller by one driving motor in an associated manner. CONSTITUTION: When a stepping motor 5 is driven, the rotation of an output gear 6 is transmitted to a carriage-driving gear 28, so that a carriage 23 is moved right on a rack plate 30 via a worm 26 spline-coupled with a carriage- driving shaft 27. At this time, in the middle of the movement when a left end part of a thermal head 13 at, the side of a rear face of the carriage 23 moves to a recessed part 8 along an inclined face 12a, the thermal head 13 is, before a printable range, pressed into touch with a platen 10 by a leaf spring 32 thereby to be faced dawn. In the succeeding two and a half rotations, the carriage 23 holding the faced-down thermal head is further moved right. When the carriage is located in the printable range during the movement, a heat-sensitive paper 3 is printed based on printing data.

Title: Restart extension method of lambda control in internal combustion engine with lambda control
Inventor: CLEMENT ALBRECHT
IPC: F02D41/14
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To reduce toxic nitrogen oxide by a simple method as much as possible in a restart process in an internal combustion engine by changing set values of λ control in a predetermined period of time so that lean extension or rich extension of an air-fuel mixture is formed. SOLUTION: A change II of a set value FR of λ control prolongs a rise integration part 110 which forms a change of an air ratio λ from a rich condition to a lean condition in a two position controller during a period of a predetermined time interval Δt so as to achieve rich extension of an air-fuel mixture. Consequently, the set value FR forms the rich extension of an air-fuel ratio of air and fuel which are jetted. Moreover, it is possible to further raise a rise diagonal face of the integration part 110 during the predetermined time interval Δt only instead of fixed extension. Rich extension of the air fly(31 mixture which is jetted, namely, restart extension of λ control, is securely done in a restart process only based on various determination standards.  Furthermore, it is possible to reduce nitrogen oxide owing to the operation through the optimum air ratio.

Title: Differential amplifier
Inventor: JIEEMUZU UU
IPC: H03F3/45
Filed: 1988-07-29
Abstract: PURPOSE: To improve the transient characteristics and inverse destroy voltage of an input stage by providing a differential transistor amplifier, error detecting means and correction circuit, converting a correction voltage to a correction current and adding it with the output current of a main differential amplifier stage. CONSTITUTION: An error voltage dV is settled at a base/emitter voltage Vbe of input transistors 46-60. The same error as this error is generated in a collector/emitter voltage Vce of detection transistors 52-50. Therefore, assuming that a signal source resistors 44-62 are ignored and the β of transistors is infinitely large, concerning a main differential output current dI of a main differential amplifier, the voltage to be impressed to a correction amplifier is only the dV. This voltage is fine and the correspondent error voltage of this stage is low and can be ignored. Therefore, the correct representative value of an error voltage between paired input transistors is impressed to the correction amplifier. When regulation resistors 50-56 are suitably selected as primary approximation, the gain fluctuation factors of these resistors can be completely excluded.

Title: Plate type heat exchanger
Inventor: NUMATA MITSUHARU
IPC: F24F5/00
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To stabilize the overcooled state by correcting uneven temperature distribution of overcooled water due to dead water zone in a water channel. SOLUTION: A water channel has an outlet side choking part 74 for blocking conduction of heat medium, formed at a part corresponding to the peripheral part of a coolant flow-out path 64a, such that the width of the water channel becomes narrower toward a heat carrier flow-out path 62. Since the outlet side choking part 74 is provided, water flowing from a water flow-in path 61 into a water channel flows, at a substantially constant rate, toward the water flow-out path 62 without standing in the vicinity of a fourth opening 84a. Consequently, the water standing in a dead water zone is not cooled to freeze in the water channel and overcooled state of the heat carrier can be stabilized.

The tunnel (106) is provided with two columns of louvers (140) along its entire length through which the air from the duct (104) flows. Air exiting the louvers (140) is deflected by a baffle plate (146) which extends the full width of the rear of the cabinet (10). The edge portions (152, 154) of the baffle plate (146) are perforated. The air thus must move out forward through the louvers (140) then laterally across the solid portion of the baffle plate (146) before turning forward again through the perforations in the baffle plate into the interior of the cabinet (10). The improved air (low greatly reduces temperature differences within the carbinet (10) when used as an oven, and the air flow over the heating elements is more uniform, reducing hot spots and thus prolonging their life.
