Abstract: PURPOSE: To use a chip coil as formed by fitting the chip seal consisting of the self-lubricating material to a seal groove of a spiral body erected on a scroll, and installing a partitioning plate which is the folded seat material of the heat resistant thin film in the space therebetween. CONSTITUTION: A seal groove 2 is provided on the tip of a spiral body of a scroll member.

Title: Filter
Inventor: CHIGA AKIHISA
IPC: F16N1/00
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To dispense with bringing a casing into a working site for an element since the element is assembled to the casing at the same time by vibration welding and to carry out the element from a factory as finished products. SOLUTION: An element 30 is assembled as a single part by sticking a filter medium 31 between a disc metallic plate 32 and a doughnut metal plate 33 having a communicative window 33a and it is put between as finished products and welded by vibration in an assembling site, thereby dispensing with bringing a part of a housing in a working site for the element 30 to do working.

IPC: F02D45/00
Filed: 1990-06-12
Abstract: PURPOSE:To prevent excessive spark advance/delay at the sudden change time of a rotational cycle and the aggravation of engine speed build-up after startup by judging that the engine speed computed from the output of a crank angle sensor after startup has reached the specified value, and forbidding this judgement until the engine speed reaches the specified value. CONSTITUTION:The change of a rotational cycle is predicted on the basis of the output of a crank angle sensor B for detecting the crank angle position of an engine A so as to estimate the engine speed after this change by a means C. The ignition timing is also set by a means D on the basis of the estimated engine speed. The sudden change of the rotational cycle is further judged by a means E, and the ignition timing set by the means D is corrected by a means F at the sudden change time of the rotational cycle. A means G then judges that the engine speed computed from the output of the sensor B after startup has reached the specific value, and the judgment made by the means G is forbidden by a means H until the engine speed reaches the above-mentioned specified value after startup.

Title: Automatic rotation frequency adjustment unit of engine test unit
Inventor: DOI TAKESHI
IPC: F02D41/14
Filed: 1978-12-15
Abstract: PURPOSE: To automatize the set operation for idling rotation frequency to improve a work efficiency by detecting the rotation speed of an engine and comparing this detection rotation speed and a set rotation speed from a rotation instructing unit with each other to adjust the rotation speed into a required value.  
     CONSTITUTION: The rotation frequency of rotation axis 2 of engine 1 is measured by rotary generator 4 and is converted to a voltage proportional to the rotation frequency by feedback function unit 5 and is sent to comparator 7. The engine is rotated in a high speed by the command from high-speed rotation instructing unit 8 at the start time of the engine; and when the engine is warmed up to the state for normal rotation, a timer is operated to send a voltage, which is set to idling rotation frequency, from low-speed rotation instructing unit 9 to comparator 7. Comparator 7 compares the set voltage value from unit 9 with the measured voltage value from unit 6, and their difference voltage is amplified 10 to adjust idling set screw 14 through DC motor 11, decelerating unit 12 and rotation joint 13. As a result, the best idling state is set automatically to improve the work efficiency.

Title: Frame synchronizing method
Inventor: UENISHI MASARU
IPC: H04J3/06
Filed: 1993-06-25
Abstract: PURPOSE:To surely conduct frame synchronization by continuing the collation of a frame synchronization pattern for received data till synchronizing signal data are lost when the result of collation of the frame synchronization pattern is unmatched after bit synchronization. CONSTITUTION:An FM receiver is provided with a reception antenna 1, an FM reception circuit 2, a control circuit 3, a shift register 4 and a ROM 5, also a reception data analysis circuit 6 in addition. Then bit synchronization is established while sensing a carrier with a bit synchronizing signal and whether or not a pattern of received data just after a bit synchronizing signal is matched with a predetermined data pattern is collated to decide frame synchronization. Every time of reception of one bit after the establishment of bit synchronization, the control circuit 3 collates the received data with the frame synchronization pattern. When the result of collation indicates unmatch, the received data analysis circuit 6 judges whether or not the bit synchronizing signal is included in the received data to decide the stop or continuance of frame synchronization processing.

Title: Coil device
Inventor: ABE HIROMITSU
IPC: H01F19/04
Filed: 1992-06-15
Abstract: PURPOSE:To provide a coil device on which the adverse effect due to leakage magnetic flux is lessened and the yield of production is improved by decreasing the leakage magnetic flux generated on the circumference of a gap. CONSTITUTION:The first leg parts 11a and 12a, where the coil 13 of the device is wound, form a leakage magnetic flux part 14 on the tip side of a substrate 11', and a gap length adjusting part 15 is formed on the tip side of the above- mentioned attenuation part 14. The leakage magnetic flux generated on the circumference of the gap 10 can be reduced by the leakage magnetic flux attenuation part 14, and as the shape of the leakage magnetic flux attenuation part 14 is not changed even when the tip face of the gap length adjusting part 15 is scraped, the length of the gap G10 can be adjusted without changing the attenuation characteristics of the leakage magnetic flux. As the gap length adjusting part 15 has a draft grade and it is formed in such a manner that its cross-section becomes almost uniform, the demolding becomes easy when the magnetic core is molded, the generation of cracks can be prevented, and the yield of production can also be improved.

Title: Control system for priority processing of event notice
Inventor: KOMURO HIROSHI
IPC: G06F13/10
Filed: 1987-06-22
Abstract: PURPOSE:To eliminate the need for control at the side of an information receiver task by registering an event notice among tasks on a holding queue of a semaphore in the order of priorities and then allocating them to the information receiver tasks in the register order. CONSTITUTION:A new event notice having the highest priority A is given to notice receiver task 40 from a notice transmitter task 30 via a semaphore 20. In such a case, the task 40 is processing the vent notice of the priority B lower than the priority A by a rank. Thus a priority even notice register means 11 registers the even notice of the priority A on a holding queue of the semaphore 20. A priority checking means 12 detects that said new event notice is registered on the head of the queue of the semaphore 20 and compares the priority A with the priority B of the event notice which is processed by the task 40. In this case, a processing state control means 13 preserves the state under processing to prepare for the processing start of the priority A since the priority A is higher than the priority B.

Abstract: PURPOSE:To obtain a combustion, being stabilized and never causing backfire, by a method wherein, a fuel supplying passage is formed by combustion plate, flat type and arranged so as to be opposed to each other, and a heat permeable body such as glass or the like to unify the temperatures of the combustion plates. CONSTITUTION:Exhaust gas, in the downstream of mixture from flame port plates 9, 10 and flames 27, 28, is decelerated as it approaches the center of a combustion chamber and forms the point of stagnation at the center of the flame port plates 9, 10 and the combustion chamber 17, therefore, the flow rate thereof becomes zero and the flames 27, 28 are stabilized. Further, the static pressure of the exhaust gas is increased as it approaches the point of stagnation and the flow rate thereof is reduced while the flow rate of the mixture 32, injected from the flame port plates 9, 10 becomes uniform in the whole of the flame port plates 9, 10, therefore, the flames 27, 28 may be unified. The flame port plates 9, 10 are arranged so as to be opposed to the flames 27, 28, therefore, temperature reduction may be reduced even upon low combustion. As a result, a combustion may be effected even with a large air ratio whereby the generating amount of NOX may be reduced.
