Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To converge the oxygen storage amount in a three-dimensional catalyst into the optimum region in the air-fuel ratio control of an internal-combustion engine and enhance the exhausting characteristics of the engine. SOLUTION: An electronic control device 30 calculates the air-fuel ratio feedback correction factor to repetitively perform the skip control and integral control so that the sensor voltage VOF of a front oxygen sensor 11a installed upstream of a three-dimensional catalyst 20 converges to the reference voltage and corrects the fuel injection amount using the obtained correction factor. Further an air-fuel ratio sub-feedback control is performed to repetitively conduct the skip control and integral control for the skip control amount of the air-fuel ratio feedback correction factor so that the sensor voltage of a rear oxygen sensor 11b installed downstream of the catalyst 20 converges to the reference voltage.  In this sub-feedback control, a large update amount concerning the skip control is taken into account, and even after transition to the integral control, the skip control amount is held constant for a certain period of time.

Title: Spark ignition type internal combustion engine
Inventor: YAN UISEN
IPC: F02B77/02
Filed: 1986-11-07
Abstract: The invention relates to a spark-ignition internal combustion engine having a combustion chamber which, at least in part, presents surface areas (10) which have been treated to reduce the octane number requirement of the engine. 
<??>The surface area to be treated may, for example, be either blasted or etched to produce surface depressions, and is then flame sprayed with copper particles to form heat-reflective surfaces. At least this latter method results in solely low-temperature heating of the walls of the combustion chamber, which can be advantageous in the case of diesel engines, but not in the case of Otto-cycle engines. 
<??>The improvement in such engines afforded by the invention is that the surface areas (10) are instead provided with at least one layer (12) which presents to the combustion chamber (1) a defining surface (9) which exhibits an extremely low reflectivity to electromagnetic waves in the wavelength range of about 0.2-7.0 microns, and which also results in diffuse reflection of non-absorbed incident waves (14).

IPC: H05K3/46
Filed: 1990-10-02
Abstract: PURPOSE:To double the number of bare chips to be mounted per unit area by sealing the chips mounted therein simultaneously upon laminating of a board. CONSTITUTION:A bare chip 2 is connected to a foot print 11-1a formed on an intermediate layer 11-3, surface layers 11-2 are superposed on both outside surfaces through adhesives 11-3, and heated. Then, the adhesives 11-3 are softened to flow to an air gap formed between the layers 11-1 and 11-2 to be formed by the thickness of the chip 2. When the adhesives 11-3 are cured, the chip 2 is sealed between the layers 11-1 and 11-2, and hence laminating of the layer 11-2 and sealing of the chip 2 can be performed in one step. In this case, other bare chip may be surface-mounted on the surface layer of a printed board with the bare chip. Thus, the number of the bare chips to be placed on the board per unit area can be doubled.

Title: Ultrasonic motor
Inventor: NOJIMA TAKASHI
IPC: H02N2/00
Filed: 1992-10-06
Abstract: PURPOSE:To provide an ultrasonic motor which can rotate stably at high efficiency even upon application of radial load to an output transmission shaft. CONSTITUTION:An elastic member 29 is placed between a mover 27 and an output transmission shaft 28 for transmitting rotation of the mover 27 to an external load. An output take-out part 28b of the output transmission shaft 28 is provided on the side of a bearing 31 located on the oscillator 24 side in order to regulate the rotational position of the output transmission shaft 28 thus taking out output from the oscillator 24 side of the output transmission shaft 28. Since the distance between a fulcrum, i.e., the bearing 31, and a working point is short, deformation of the output transmission shaft 28 due to load functioning thereon can be retarded when abnormal force is applied radially to the output transmission shaft 28. Furthermore, deformation absorbing effect of the elastic member 29 mounted on the mover 27 can be exhibited by providing the output transmission shaft 28 with a free end at a part coming into contact with the elastic member 29.

Filed: 1986-11-10
Abstract: PURPOSE:To obtain images of good quality which are free from photographic fog and have good gradation and have not negative characteristics by allowing a small quantity of magnetic particles to exist on a developing area. CONSTITUTION:A magnetic brush 51 is formed with toner particles holding fine silica powder on surfaces and magnetic particles so that 5-80mg/cm<2>, preferably, 10-70mg/cm<2> magnetic particles 27 exist on the developing area of a developer carrier. In the developing area, nonmagnetic toner particles 28 are moved back and forth between a latent image holding body and the surface of the developer carrier as well as the surface of the magnetic brush 51 formed on the surface of the developer carrier to develop a latent image. These nonmagnetic toner particles display only <=10emu/g magnetization in 5,000Oe external magnetic field and cannot practically act as a magnetic toner. Thus, excellent developed images are obtained with a very high development efficiency.

Abstract: PURPOSE:To make use of a valve chamber as a flow path for working fluid, and make for compactness and higher speed by forming an inlet side passage at the lower center section of a valve body, and concurrently forming exhaust side passages at both the sides of the aforesaid inlet side passage in the sliding direction. CONSTITUTION:An inlet port 6 communicated with a valve chamber 2 is opened to the side periphery section of a valve seat 3 in the width direction, outlet ports 7A and 7B and exhaust ports 8A and 8B are opened to the center section of the valve seat 3 while being arranged in parallel in the sliding direction of each valve body 5, an inlet side passage 9 is formed between the two valve bodies 5, which allows the outlet ports 7A and 7B to be selectively communicated with the valve chamber 2, and concurrently exhaust side passages 10A and 10B are formed in the respective valve bodies 5, which communicate the outlet ports 7A and 7B isolated from the valve chamber 2, with the exhaust ports 8A and 8B. By this constitution, since the valve seat 3 and the valve bodies 5 can be made small in size in the sliding direction of each valve body 5, and the slide valve can also be made small in size, the sliding resistance of each valve body 5 can thereby be decreased with the contact area of each valve body 5 with the valve seat 3 made small, so that the switch-over speed can be made high.
