IPC: G11B7/09
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To supply an optimum focus driving voltage after discriminating a kind of optical disk by storing reviously a focus driving voltage corresponding to the kind of optical disk as a prescribed value. SOLUTION: When a measuring time of a timer of a microcomputer 25 exceeds a prescribed time stored previously in a 1st ROM 33, a voltage value V2 at a peak held by a peak hold circuit 24 is stored in a RAM 32. Subsequently, if the voltage V2 exceeds a prescribed threshold TH2 stored in the ROM 33, the optical disk is judged as a CD. Then, if not, the judgement is made as a DVD. In this case, the threshold TH2 is specified as an intermediate value between a max. amplitude voltage of a focus error signal detected by an optical pickup 22 with +1st order light of the CD and that of the DVD.  Then, CD and DVD focus driving voltages FDE-C and -D stored in a 2nd ROM is read out by the microcomputer 25 to issue a control command to a servo coil driving circuit 29, and hence an objective lens is moved to their respective positions, so that focusing can be performed in the same time irrespective of these kinds of optical disks.

Title: Data transfer control method
Inventor: KODAMA SATOSHI
IPC: G06F13/12
Filed: 1994-09-20
Abstract: PURPOSE:To prevent deterioration in performance of a communication cable due to the transfer delay time by setting intervals of data requests on the b ' data transfer speed between a storage control part and an information storage part when the data requests are issued. CONSTITUTION:The storage control part 3 and information storage part 4 which are connected to a host processor 1 constitute an information storage subsystem 2. The storage control part 3 receives a data transfer start indication 11 and transmits a 2nd data request 13 even between the end of the transmission of a 1st data request 12 and the reception of 1st data, so a buffer 6 never becomes empty. Then intervals 17 between respective 2nd data requests 13 are calculated on the basis of the mean transfer speed of data from the storage control part 3 to the information storage part 4. Consequently, the data mean transfer speed between the storage control part 3 and host processor 1 never exceeds the data mean transfer speed between the storage control part 3 and information storage part 4, so the buffer 6 never overflows.

Title: Powe supply built-in scr gate driving circuit
Inventor: KURISUTOFUAA OUSUTEIN SUMISU
IPC: H03K17/79
Filed: 1990-08-28
Abstract: PURPOSE: To selectively limit the scattering of a drive energy by lowering the base of a second PNP bipolar transistor to a low level by a first NPN bipolar transistor and supplying a drive signal to the gate of a silicon controlled rectifier element(SCR). CONSTITUTION: The base of an output transistor Q4 is lowered to a low level by a transistor Q2 for supplying a drive signal to the gate of an SCR. A transistor Q3 forms a limiter circuit for stealing a base drive from the transistor Q4 and limits current that passes through the transistor Q4, when the current of a resistor R7 exceeds a desired current limitation along with the resistor R7. Thus a proper gate current to the SCR where amplitude is fixed, regardless of a potential between the both edges of the SCR is assured, hence limiting the scattering and leakage current of power to a low level.

Abstract: PURPOSE:To prevent passengers from dropping even if passengers stand on the step member during the shift of a step member or when a drive section is broken by moving the step member so that it may always keep itself parallel with the top surface of a platform. CONSTITUTION:In lifting a lifting operation part 5, first of all, a hydraulic cylinder 16 is stretched to rotate a parallel link 13, as a result, a slide base 3 moves from a mounting frame 1 to the gap between a train 9 and platform 8. In the next step, when a hydraulic cylinder 21 is stretched, crossing angle of members 19 and 20 is made to change, lifting a lifting member 5, as a result, the stepping member 6 on the lifting member 5 is made to lift always keeping its position parallel with the top face of the platform 8 and stops at the position where matches the top surface of the platform 5. With this constitution, even if an exit and entrance driving section 4 or lift drive section 7 are broken, there is not such a danger that passengers drop.
