Title: Air-fuel ratio control device of engine
Inventor: NAKAJIMA YUKI
IPC: F01N3/20
Filed: 1991-08-19
Abstract: PURPOSE:To eliminate an influence exercised by erroneous learning occurring owing to introduction of secondary air and to promote the progress of learning during deterioration of a catalyst by a method wherein the more deterioration of the catalyst progresses, the more a learning prohibition time decreases. CONSTITUTION:When a secondary air introduction device 46 is actuated by means of a working means 47 during idling, surplus oxygen is adsorbed to a catalyst, and the adsorbed oxygen is discharged for some time starting from the stop of operation of the secondary air introduction device 46. The discharging time responds to the degree of deterioration of a catalyst and the more the degree of deterioration of the catalyst is increased, the more the discharging time is decreased. Therefore, when the discharging time is set as a learning prohibition time by means of a set means 49, a learning prohibition means 50 prohibits update of a learning value for the learning prohibition time.

Title: Optical head
Inventor: GOTO HIRONORI
IPC: G11B7/085
Filed: 1985-09-19
Abstract: PURPOSE:To miniaturize the size of the entire head by moving a convex lens for light collection and diffusion collecting and diffusing a light beam from a light source in response to a face deflection of an optical memory medium in the light axis direction and moving the focus of the convex lens for light collection and diffusion based on the movement. CONSTITUTION:The light beam emitted from a laser light source 13 is made incident in an optical eye 16 via an access error generator 14 and an access servo actuator 15. After the light beam being made incident on the optical eye 16 is reflected in a mirror 17, the beam is transmitted through an objective lens 18 and formed into a minute spot on a recording face. The light reflected in an optical disc 10 reaches the access error generator 154 via the optical eye 16 and an access error signal and an information signal are extracted from the generator 14. The access error signal is fed back to the access servo actuator 15 to adjust the zoom mechanism in the actuator 15 so as to minimize the feedback quantity.

Title: Symbol clock reproducing circuit
Inventor: OISHI MUTSUHIKO
IPC: H04L7/00
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To reproduce a symbol clock signal with a correct phase even when phase offset is residual in a base band signal. SOLUTION: A phase quantizing part 1 samples an in-phase signal and a quadrature signal, for which the frequency of a received modulation wave is converted to the base band signal, calculates the phase and performs quantization (quantized phasing) later and a phase change amount calculating part 4 calculates the phase change amount of the said quantized phase at plural symbol cycle times. A timing detecting part 5a detects the timing when the said phase change amount is closest to a phase change amount determined for each modulation system. A timing synchronizing means 3 reproduces the symbol clock synchronized with the said timing. Thus, even when phase offset is residual, the clock signal can be reproduced with the correct phase.

IPC: H05K3/22
Filed: 1992-08-04
Abstract: PURPOSE:To cut off excessive bonding wire automatically by making a cut in a chip. CONSTITUTION:A bonding wire 3 is laid above a pad 2 formed on the surface of a printed board 1 while previously coated with solder such that the leading end of the wire 3 projects from the pad 2.

Title: Ac switch for switching bypass power of uninterruptible power unit
Inventor: NOZAKI TOSHINOBU
IPC: H02J9/06
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To mitigate the influence of instantaneous power failure of a bypass power source by keeping ON condition while the switch to supply the bypass power between the bypass power source and load is on. SOLUTION: An uninterruptible power unit 1 stops power supply by the occurrence of abnormality. Moreover, when an ON signal is inputted into the semiconductor element 32 of an AC switch 3, the semiconductor element 32 is turned on, and supplies power through a breaker 5 from a bypass power source 4. Accordingly, switching without a break from the uninterruptible power unit 1 to the bypass power source 4 can be realized. Furthermore, the semiconductor element 32 of an AC switch 3 keeps the ON condition also after turning on of the switch 31 of the AC switch 3. Accordingly, the influence of the instantaneous power failure of the bypass power source can be prevented to its minimum by making the semiconductor element of the AC switch act upon it.

Title: Spreading and leveling device for high viscosity pavement material
Inventor: KIMURA KOHEI
IPC: E01C19/48
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of spreading and leveling work by providing a traveling vehicle with a storing and discharging machine, a spreader and a leveling device, spreading a pavement material on the road floor surface by a spreader plate, bringing the edge part into contact with the pavement material, and rolling the spread and leveled pavement material. SOLUTION: A traveling vehicle 14 kneads a high viscosity pavement material 76 by a mixer 16, and then advances while delivering the material to a road floor surface 12 by a transport mechanism 18. Next a spreading plate 62 of a spreader 20 is driven to spread the pavement material 76 discharged to the road floor surface 12 in the lateral direction by a spreading plate 62, and the material is leveled to be substantially uniform in thickness by a leveling plate 88. Compaction is performed by a rolling roller 108. Thus a series of processes from kneading of the pavement material 76 to compaction can be continuously performed by one device so as to improve the work efficiency. Further, the time required by processes of mixing the pavement material 76 to the completion of compaction can be reduced. Thus adhesion of the high viscosity pavement material 76 and the occurrence of thickening can be prevented.

Abstract: PROBLEM TO BE SOLVED: To start a commutatorless motor having a permanent magnet rotor and no pole position detecting means, e.g. a Hall element, surely while positioning the rotor surely using a bootstrap system inverter circuit. SOLUTION: When an IGBT (switching element) 3d is turned on at the starting of a motor, a current flows from a DC power supply 4 through a resistor 5 and a diode 6a to a capacitor 7a which is thereby charged to provide a DC power supply for an IGBT 3a. After the IGBTs 3a-3f are turned off for a predetermined time, the IGBTs 3a, 3e are turned on and the rotor of a commutatorless motor 12 is positioned. In this regard, a capacitor 7b is charged from the DC power supply 4 through a resistor 5 and a diode 6b to provide a DC power supply for the IGBT 3b. Consequently, the commutatorless motor 12 is started and when the IGBT 3f is turned on, a capacitor 7c is charged from the DC power supply 4 through the resistor 5 and a diode 6c to provide a DC power supply for the IGBT 3c.

Title: Production of lactic acid ester
Inventor: TANIYAMA EIJI
IPC: B01J23/44
Filed: 1994-09-01
Abstract: PURPOSE: To advantageously produce a lactic acid ester under mild conditions by reducing an industrially readily available glycidic acid ester as a raw material with hydrogen in the presence of a reducing catalyst. CONSTITUTION: This method for producing a lactic acid ester of formula II comprises reacting glycidic acid ester of formula I (R is a 1-8C alkyl) used as raw materials with hydrogen in the presence of a reducing catalyst at a normal pressure or under pressure. Palladium carbon is especially preferably used as the reducing catalyst. Furthermore, the glycidic acid ester of formula I of a raw material is readily obtained from an acrylic acid ester which is a general-purpose industrial raw material. Since this method does not use a poisonous raw material such as hydrogen cyanide or carbon monoxide and does not produce a by-product such as ammonium sulfate, the method is advantageous. The lactic acid ester is useful as a solvent for resist and coating.
