Title: Internal-combustion engine controller
Inventor: HATA YOSHITAKA
IPC: F02P5/15
Filed: 1981-10-28
Abstract: PURPOSE:To control an engine so that it may be operated at the most efficient and  stable combustion as well as to prevent it from knocking, by adjusting property the  ignition timing, fuel supply and exhaust reflux rate with the help of the detected value  of cylinder internal pressure varied by combustion. CONSTITUTION:The cylinder internal pressure signal detected by a detector 11 and the  engine shaft rotating position signal detected by a detector 12 are inputted into a detection circuit 13 and thereby the value of the cylinder internal pressure maximum  position is found, upon which this value is inputted into a comparator 16 in order to  judge whether an engine is being operated at its maximum output or not by comparing  said value with the values in the desired range. According to the result of judgement,  an ignition timing adjuster 18 and an exhaust reflux rate adjuster 19 are trued up to operate the engine at its maximum output. Further, the value of the cylinder internal  pressure maximum differential positive is found by means of a differentiator 14 and  detection circuit 15, and the value is compared with the desired values by means of a  comparator 17 in order to decide whether combustion of the engine is stabilized or not.  Also, according to the result of judgement, the ignition timing adjuster 18, the exhaust  reflux rate adjuster 19 and air-fuel ratio adjuster 20 are as well trued up and thereby  combustion of the engine is controlled to the extent of being so stabilized enough.

Abstract: PURPOSE: To facilitate taking of a reading at a comparatively high precision, by a method wherein several digital weighing data of a weighing device for baby are sampled through a computer, and a fixed indication is performed only when the value is larger than a set value.  
     CONSTITUTION: Several weighing data of a weighing part 6, such as load cell of a weighing device for baby, are sampled according to programs of a ROM10 by means of a CPU9 through the working of an AD converting unit 7 and a data selector 8, and are stored in a RAM11. In the meantime, status, such as hold keys, tare keys, and a minimum weight (500g) are stored in the RAM11 from a status input 14 through a data selector 15. Weighing value in the RAM11 is compared with the set value of the minimum weight, only data exceeding the set value is fixed, and the weight is indicated in an indicator 20 through a digit decoder 18 and a segment decoder 19. This permits facilitation of taking a reading at a comparatively high precision.

Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to maintain reliably the site of an object of measurement on a thin plate at a set temperature without a temperature unevenness by a method wherein the thin plates and high-low temperature units, which are placed on a stage part, are moved relatively to each other using an X-Y movement mechanism and the thin plate is locally heated or cooled by the high-low temperature units. SOLUTION: An IC wafer, which is an object of inspection, is placed on the upper side mount surface 4A of a stage part 4 to make a test for the wafer. A circular space 21A, wherein high-low temperature units 6 can be moved relatively to the IC wafer, is provided in the central part of a hanging bell-shaped stage base of the stage 4. The wafer placed on the upper side mount surface 4A of the stage part 4 is locally (only the site of an object of inspection) heated or cooled by the units 6. When the site of the object of inspection on the wafer reaches a set temperature, probes of a probe part are brought into contact with the surface of the wafer to make a characteristic test for a measurement of a microcurrent or the like.  Thereby, the units 6 can be significantly miniaturized and at the same time, the generation of the deterioration of the detection accuracy of a prober due to a temperature unevenness can be reliably prevented.

Title: Flow noise control system for throttle valve
Inventor: NAKASE YOSHIHIRO
IPC: F02D9/10
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a flow noise control system that is able to check any noise to be produced at a time when a throttle valve installed in an intake passage or the like of an internal combustion engine is opened. SOLUTION: Two circular low barrier members 9 and 10 are installed in an inner wall surface 6 of an air passage 2 at the downstream side of a throttle valve 3 as a resistant means imparting a resistor to a flow passing through a vertical pair of clearances 7 and 8 to be formed at the valve opening initial stage of this valve 3. Therefore flow velocity and flow rate in the flow passing through these clearances are decreased, whereby the extent of noises to be produced when flows out of the paired clearances 7 and 8 are joined together is reduced. The barrier members 9 and 10 may be plurally installed in parallel, or deformed to some extent as well. In addition, as another resisting means, fins of more than one piece along a central axis of the air passage may be used as well.  Moreover, in place of the resisting means, a turbulence generating means such as dimples made up on the inner wall surface 6 and such a wire as extending to the downstream side along the central axis of the air passage may be installed to generate a turbulent flow along the inner wall surface 6.

Title: Automatic analyzer
Inventor: HANAWA MASAAKI
IPC: G01N35/00
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To predict a change with the lapse of time in sliding torque so as to prevent a device from stopping for improving reliability by comparing a pulse number given to a pulse motor to be driven with a pulse number required to a predetermined position and storing the pulse number in a normal sliding torque time and that in an abnormal time into a storage device. SOLUTION: Firstly, a stop is determined by a designated detector after operation. Secondly, the present condition of the detector is checked again. When the detector is in a normal condition, it is determined whether the number of the remaining pulses is zero or not. If the number of the remaining pulses is not zero, a shift to determination of a normal value range for the remaining pulses is carried out. It is determined whether the number exceeds an upper limit value of the normal value range or not, and if the number is not above the upper limit value, the lower limit value is checked and the operation is ended normally if the number is above the lower limit value. If the number of the remaining pulses is less than the lower limit of the normal value range, this information is stored as an alarm.  In addition, if a fixed number or more of abnormal action occurs, the alarm is displaying for warning an operator. In this way, alarm information is analyzed, so that a change in sliding torque with the lapse of time can be predicted.

Title: Collected dust disposal method
Inventor: MITSUSHIBA YASUO
IPC: F23G7/00
Filed: 1990-06-29
Abstract: PURPOSE:To make it possible to collect dust collector dust which is generated when sludge is burn-molten efficiently and reduce dust in the final exhaust gas effectively as much as possible by a method wherein dust collector dust which is separated and collected from exhaust gas is mixed in wet sludge prior to drying, and the dust collector dust is collected by making it stick to the wet sludge and returned to a melting furnace. CONSTITUTION:As mentioned before, wet sludge to which dust collector dust is mixed to be adhered is burn-molten by repeating a series of processes such as dry-kneading by a multi-stage dryer 3, crushing by a crusher, 4, burn-melting by a rotary flow melting furnace 5, dust collecting by an electric dust collector 6 and mixing of dust collector dust in wet sludge; and the collected dust is made into slug with high efficiency. In this dust collector dust disposal method, dust in the exhaust gas discharged from the melting furnace is always collected and adhere-mixed in wet sludge, and therefore, the collected dust is not re-mixed in the exhaust gas by flying in the rotary flow melting furnace 5, and the dust can be disposed in the plant system itself. For this reason, the rate of transforming into slug of the dust is increased, and a dust volume in the final exhaust gas can be reduced, and the plant can be made into a closed system.
