Title: Variable valve system for internal combustion engine
Inventor: SAKAMOTO ATSUHIRO
IPC: F01L13/00
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To generate a lift difference between suction/exhaust valves in the same cylinder by providing valve springs having a difference between the exciting force to at least one suction/exhaust valve when closing it and the energizing force to the other suction/exhaust valve when closing it. SOLUTION: The energizing force of a valve spring 3a on the left side when closing a valve is set smaller than that of a valve spring 3b on the right side. When a cam lift is started, the lift of a suction valve 2a on the left side is started earlier than a suction valve 2b on the right side, and a lift difference is generated between them at the start of the cam lift. The lift difference is eliminated at the maximum lift of the suction valves 2 because the right and left valve springs 3b, 3a are set to the same energizing force, and both suction valves 2a, 2b can be set to the maximum lift. A similar lift difference is generated when the cam lift is reduced. Since the lift difference is generated, a suction air swirl is generated at the time of the low rotation of an engine, the gas flow is activated, and the combustion deterioration at the time of low-lift control is prevented.

Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To correct a sound volume difference to be almost constant in a listening sense by automatically correcting a sound volume difference of an output voice signal caused in the case of switching a signal source. SOLUTION: The user controls a remote controller 7 to set a sound volume correction amount to correct a difference for a reception sound volume level between signal sources such as a VHF and a BS, then a microcomputer 5 stores the sound volume correction amount to a memory 6 and the sound volume level instructed by the usual sound volume level by the remote controller 7 is stored in the memory 6 as reference voice data. Then in the case of channel selection, the microcomputer 5 reads voice reference data and the sound volume correction amount from the memory 6 and controls a voice circuit 4 so that the output voice level indicates a sound volume denoted by the sound volume data obtained by the addition of the data above.  For example, in the case that a source VHF is changed into a source BS, the sound with almost a constant sound level is outputted from a speaker 8 without manual sound volume adjustment by the user.

Abstract: PURPOSE:To form the high density electrode terminal to be used for the external wiring by a method wherein the electrode terminal which will be used to connect wirings to outside is made into multilayer constitution through the intermediary of an insulating film and the above is then formed in stepped type. CONSTITUTION:An insulating film 51 is formed on a substrate 1 and an electrode wiring is formed thereon.

Also, the electrode terminal 42 required for outside wiring is left over, an insulating film 53 is covered thereon, and the layers of necessary number are formed in the same manner. As the terminal parts required for the external wiring are formed by multilayer wirings and arranged in stereoscopical form as above- mentioned, short-circuit troubles are lessened by the staircase-shaped stepping 6 which effectively works when an external wiring connection is performed, thereby enabling to reduce the wiring pitch and to accomplish the formation of the highly densed electrode terminal.

Abstract: PURPOSE:To detect a flow rate in a vector manner, by a method wherein, in a laser Doppler flow rate gauge, a maneuvarability is improved by employing a  optical fiber at a sensor part, and the optical fiber is placed two-dimensionally  or three-dimensionally. CONSTITUTION:A measuring object is irradiated with a laser light of frequency omegao from a laser light source 1 after the laser light passes through half mirrors 3, 3a, a lense 4, and a optical fiber 10. Meanwhile, a frequency of a laser light passing through half-mirrors 3 and 2 is shifted by a frequency shifter 15 into a frequency omegao+omegac, and produces a reference light passing through half-mirrors 2a and 3a to a lens 7. A frequency of a reflection light from the measuring object is shifted into a DELTAomega frequency, and the reflection light is reflected in the direction of the lens 7 by the half-mirror 3a, the light entering an avalanche photo diode 16 togetherwith said reference light. In a correlator 13, an electric signal, corresponding to a difference omegac-DELTAomega in frequency between the two lights, is obtained, and a flow rate and a direction are found from the absolute value and polarity. The optical fiber 10 is arranged two-dimensionally or three- dimensionally so that it is positioned at a given angle, and this permits finding  of two-dimensional or three-dimensional flow velocity vector.

Title: Bus controlling system
Inventor: NAKASHIMA TAKENOBU
IPC: G06F11/30
Filed: 1980-12-01
Abstract: PURPOSE:To prevent a bus line from being locked, by initializing a transfer request of a DMA device, if no transfer is made for a fixed time from the transfer request of the DMA device via the bus line. CONSTITUTION:When a transfer request signal is transmitted from a DMA device to a CDA bus connected via a customers DMA adaptor to a high-speed bus, a J-KF/F21 is set and a BUSY of Q output goes to ''H''. As a result, a monostable multivibrator 22 is set to output a pulse of a fixed width. The pulse width is set a little longer than the time required for transfer. Thus, if a failure takes place, when the CDA bus is detected for the occupancy with the trailing edge of the output pulse of the monostable multivibrator 22, it is detected that the DMA device is in failure and an initializing signal is transmitted to the CDA bus.
