Patent JP-H088831-A (JP)
Title: Optical transmitter
Inventor: TAWARA YOKO
IPC: H04B10/07
Filed: 1994-06-22
Abstract: PURPOSE:To attain the compensation operation to obtain an optimum output waveform duty ratio sequentially and automonously without the effect of component dispersion and temperature fluctuation in an IC circuit by controlling a reference voltage of an optical signal output drive means to reduce an error between a monitor signal and a prescribed signal of input data. CONSTITUTION:A mark rate monitor voltage from a mean value output circuit 108 is applied to an inverting input terminal of a comparator 106 and an optical output monitor voltage from a PD 103 is fed to a noninverting input terminal. Thus, when a reference voltage REF given to an LD driver circuit 101 rises, an output pulse width is made narrow and an optical output power is reduced, and when the reference voltage decreases conversely, the output pulse width is made wider and an optical output power is increased. Then duty ratio of an optical output waveform of an LD 102 is controlled so that the optical output mean power of the LD 102 is equal to the input data mean value output of the mean value detection circuit 108 independently of the internal configuration of the LD driver circuit 101 through the negative feedback as above.

Abstract: PROBLEM TO BE SOLVED: To provide the information distribution method and the information distribution device where information stored at distribution from an external information source is not useless updated thereby preventing connection of useless calls in an external stationary network and newest information is distributed to each terminal at all times. SOLUTION: Upon the receipt of an information distribution request from a mobile terminal 40a, a base station 10 connects an information service device 30 once to the request to acquire only an updated date and time of the requested information. An information management means 15 collates the acquired update date and time with an update date and time of the information stored in an information storage means 14 to discriminate which is newest.  When the information stored in the information storage means 14 is newest, a control section 16 distributes the information from the information storage means 14 to the mobile terminal 40a, and when the information in the information service device 30 is newest, the control section 16 acquires the newest information from the information service device 30 and distributes the information to the mobile terminal 40a and updates the information in the information storage means 14.

Title: Supercharger control device in engine
Inventor: MOCHIZUKI YOSHIYUKI
IPC: F02B33/44
Filed: 1984-07-05
Abstract: PURPOSE:To prevent, as possible as it can, both temporary torque-down and torque shock just after stopping of the drive of an air pump, by opening a control valve at a high load side which is higher than the engine load so that the introduction of intake-air from a communication passage is initiated prior to the stopping of the drive of the air pump. CONSTITUTION:When a throttle valve 5 is actuated in its opening direction upon acceleration, a control valve 11 starts its closing operation simultaneously with the drive of an air pump 7 so that it gradually closes, and a part of sucked air which has been pressurized by the air pump 7 is relieved from a communication passage 10 to the upstream side of the air pump 7 just after starting of supercharge operation caused by the air pump 7. When the throttle valve 5 is actuated in its closing direction upon deceleration, the control valve 11 starts its opening operation at a high load side which is higher than that at the time point at which the air drive of the air pump 7 is stopped, and therefore, the effect of supercharge operation due to the air pump 7 is gradually reduced, thereby no abrupt variation in intake-air pressure upon stopping of the drive of the air pump is brought about.

IPC: B60R25/24
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To improve convenience in use while keeping thief prevention even when power is not supplied to each part due to lowering of battery voltage. SOLUTION: When battery voltage is lowered, power is not supplied to each part even by setting ON a main switch. A user therefore starts an engine by operating a kick pedal.

A spherical part formed at a central part of a quartz tube forming a discharge lamp 1 is formed by combination with a curve having a curvature at two times or more of the maximum radius thereof. With this structure, all of the halogenated material inside of the light emitting tube is evaporated without generating the coldest part inside of the light emitting tube during the lighting. In this case, when the curvature of the curve to be combined with the spherical part becomes a curvature less than two times of the maximum radius thereof, a space around the electrode in right and left of the spherical part becomes large, and the sealed halogenated material is stayed so as to generate a trouble in a lamp function.

Filed: 1977-11-24
Abstract: PURPOSE: To prevent the blow-through, improve the igniting property and reduce the fuel consumption, by changing the mixture supply for low-load running or high- load running.  
     CONSTITUTION: Pistons 8, 9 are movably fitted in a cylinder 5. A thick mixture is introduced into the cylinder through a first scavenging port 24. A second scavenging port 25 is provided in a position of better opening time than the first scavenging port 24 to supply a thin mixture or air into the cylinder 5. Combustion gas is discharged from the cylinder through an exhaust port 13. A deflector 32 slows down the flow of the thick mixture from the first scavenging port 24 under low-load running. A scavenging restrictor valve 32 stops the supply of the thin mixture or air from the second scavenging port 25 under low-load running. An exhaust restrictor valve 30 reduces the degree of opening of the exhaust port 13 under low- load running. Compression ignition running is performed under low load. Spark ignition running is performed by a spark pulg 12 under medium or high load. Thereby, the blow-through is prevented, the igniting property is improved, the fuel consumption is reduced, and the amount of discharged HC is decreased.
