摘要:
The invention relates to a wiper blade that secures a proper error angle, wherein the wiper blade is comprised of a rubber blade and a resilient member composed of a plate spring to which a twisting feature is applied. A posture-correcting portion applies a twisting feature to the resilient member so that the full length of the resilient member and rubber blade can be curved in a spiral direction. By twisting, the resilient member approaches its natural state, and both the tip and base end portions of the rubber blade's lip portion in the lengthwise direction are adjusted in directions opposed to each other, thereby correcting the posture thereof.

A winding structure of induction electric apparatus cooling disc windings within a cooling block evenly. With respect to a pair of cooling blocks including a cooling block A disposed upstream of axial insulating cylinder cooling flow of a blocking plate blocking a vertical cooling passage and another cooling block A disposed downstream of the axial insulating cylinder cooling flow of the blocking plate, a vertical guide cooling passage splits an outer vertical cooling passage into two parts. The vertical guide cooling passage includes a side face of the disc windings and a flow passage adjusting guide plate with the flow passage adjusting guide plate placed along the circumference of the disc windings with two ends facing the disc winding side, surrounding the disc windings disposed upstream of the axial insulating cylinder cooling flow of the blocking plate and the disc windings disposed downstream of the axial insulating cylinder cooling flow of the blocking plate.

A laser waveform generation function is provided in a laser driving waveform generator 2 near a laser 3. A recording clock generator 9 is included in the laser driving waveform generator 2 to generate a clock with a frequency higher than that of a synchronizing clock 202. This allows a recording laser current (waveform) to be generated without transmission of a high frequency signal from the modulator 6. Further, because the synchronizing clock 202 is stopped upon a reproduction operation including reproduction operation in an ID unit, undesired effects on a reproduction operation such as ID reproduction can be reduced. Because the response speed of the recording clock generator 9 can be changed, a high precision clock can be generated. Thus, a high-precision recording laser current (waveform) can be generated.

An information recording/reproducing apparatus which can record and reproduce information data into and from various kinds of recording mediums has a laser driver which enables recording strategy control for each kind of recording medium. The laser driver receives an NRZ binary signal and a clock signal synchronized with the NRZ binary signal from a modulation circuit, and generates a recording current signal corresponding to the NRZ binary signal. The laser driver includes a PLL circuit disposed in the laser driver which oscillates at a recording frequency, and an unlock detection circuit which detects an oscillating condition of the PLL circuit and outputs a detection signal indicative of the oscillating condition of the PLL. A recording operation of the information recording/reproducing apparatus is controlled based on the detection signal outputted from the unlock detection circuit.

An information retrieval scheme using classification trees with respect to a plurality of information sources connected to a network is disclosed, where each classification tree having a hierarchical structure defined in terms of entries. In the information retrieval apparatus, classification tree class information for each classification tree class defined among entries constituting each classification tree is managed, where each classification tree class information indicating retrieval condition parameters for each classification tree class. Then, the information retrieval is controlled by receiving from a user a retrieval request indicating a retrieval target entry that was obtained by the user by tracing the classification trees, generating retrieval commands with respect to selected information sources among said plurality of information sources by referring to each classification tree class information corresponding to the retrieval target entry that is managed by the class definition unit, obtaining a retrieval result of a retrieval with respect to the selected information sources using the retrieval commands, and returning the retrieval result to the user.

The wiper control method is capable of preventing damages on a wiper due to erroneous operation of the wiper when a vehicle is subjected to a car washer with its wiper operation kept in an "AUTO" mode, and the wiper automatically operates without troubles while driving. The wiper control method is used for an automatic wiper system which automatically controls wiper operation of a vehicle by sensing the climate condition by a rain drop sensor 7, and the state of a door mirror of the vehicle is detected by a mirror folding detection switch 5. When the door mirror is folded, wiper operation control performed by the automatic wiper system is stopped so that the wiper is not operated even if the rain drop sensor 7 detects a rain drop.
摘要:
A microcomputer 4 responds to an instruction signal to turn the load L on or off to control the FET 2 through the drive circuit 5. The microcomputer 4 samples an electric current I.sub.L which is supplied through the A/D converter 6 and which flows in the load L at every predetermined sampling time T.sub.S and subjects the sampled electric current I.sub.L to a comparison with a known rated current value I.sub.R for the load L. When I.sub.L .gtoreq.I.sub.R is satisfied, the microcomputer 4 starts counting energizing time T. When the accumulated value of I.sub.L .times.T.sub.S is enlarged to a predetermined value S.sub.O, the microcomputer 4 turns the FET 2 off. When the detected electric current I.sub.L is larger than an upper limit I.sub.O (>I.sub.R) determined previously, the microcomputer 4 immediately turns the FET 2 off through the drive circuit 5.
