Abstract: PURPOSE:To suitably control a vehicle slip with unnecessary ASB control eliminated and also a wheel rock condition quickly released by setting the thresholds of deceleration and a slip ratio in a vehicle with the friction factors of different road surfaces added respectively. CONSTITUTION:A body speed is calculated with a means 30 based on a wheel speed detected with means 26-29, and also a wheel slip ratio is computed with a means 31 based on the wheel and body speeds in a control unit UTR. An adjustable speed is calculated with a means 32 based on the wheel speed. Moreover a means 37 controls a means 38 for adjusting brake pressure respectively so that the brake pressure can be pressure-raise-kept when deceleration directly after brake-starting becomes a threshold or less, and the brake pressure can be decompressed when the slip ratio becomes a threshold or less. In this case, the threshold of deceleration memorized in a means 35 is read with a means 34 in a high mu road based on a road surface condition presumed with a means 33. On the other hand, the threshold of a slip ratio memorized in the means 35 is read with the means 34 in a low mu road.

Title: Recording/reproducing system for tracking signal
Inventor: NUMAZAWA JUNJI
IPC: G11B5/588
Filed: 1986-07-07
Abstract: PURPOSE:To detect the center position of a track with high accuracy by carrying out previously the DC demagnetization in a recording mode so as to secure different DC magnetized states between the right and left sides set on the basis of the center of a recording track. CONSTITUTION:A main signal recording/reproducing head 23 is set under a DC magnetized state so that the track center is coincident with 25 and 25'. Then the head 23 causes the inversion of magnetization in response to the recording signal. The direction of the DC magnetization caused by the tracking signal recording/reproducing heads 21 and 22 is reversed on a recording track #2 adjacent to a recording track #1. The track position is detected from the output of the head 23 or the differential output between both heads 21 and 22. Thus, it is not required to put a special pilot signal for detection of the track position into the recording signal. Then the availability is improved with a recording signal band.

Title: Battery holder for electronic and electric equipment
Inventor: AKAMATSU KENJI
IPC: H01M2/10
Filed: 1994-06-16
Abstract: PURPOSE:To allow batteries of two kinds of size to be mounted by letting a flexible sheet rested on one end of a rectangular plate having a cut-out guide section be moved into a cylindrical case at the other end, and thereby inscribed therewith by a lever only when a small size cell is housed in. CONSTITUTION:A battery case 1 is made out of a rectangular plate which is flat at one end, bent into a cylindrical shape at the other end, in which a SUM-3 type battery 13 is inserted, and has a cut-out guide section 2 formed in the direction normal to the cylindrical axis roughly at the center over the surface of the plate. When a SUM-3 type battery is inserted in, since a movable sheet 3 is rested over the plane section, no insertion is thereby prevented. In the case of a SUM-4 type battery 14, the operation of a lever 4 permits the sheet 3 to be moved in the extension direction of the guide section 2, and thereby inscribed with the inner surface of the cylinder. The inner diameter of the inscribed section shall be identical to a diameter in which the battery 14 is inserted. Besides, the back face of the sheet 3 is provided with a projected section 5 which is inserted into the guide section 2, and is wider at its tip end than its width. Besides, a positive electrode 6 can be brought into contact with the anodes of two kinds of cells because the electrode is moved by a spring provided for the back face.

Filed: 1989-06-23
Abstract: PURPOSE:To continuously extend a memory address by a single memory controller without being limited by the physical arrangement of memory blocks by selecting the memory block to be accessed based on coupling between the arranging state and address of the plural memory blocks. CONSTITUTION:An informing means 2 is provided to inform the arranging state of plural memory blocks 4, 5, 6 and 7 and a memory block selecting means 3 is provided to select the memory blocks 4, 5, 6 and 7 to be accessed based on the coupling between the arranging state, which is informed by this informing means 2, and address of the plural memory blocks 4, 5, 6 and 7. Namely, when an instruction from an address 1 is executed from a processor 1, the memory block selecting means 3 selects the access destination of the memory block based on the combination of the address, which is instructed from the processor 1, and arranging state of the memory blocks which is informed from the informing means 2. Then, the allocation address of the plural memory blocks is virtually accessed as the continuous addresses. Thus, even when the respective memory blocks are in various sizes, the memory blocks can be made continuous.

Title: Multipolar dc motor
Inventor: KOMATSU FUMITO
IPC: H02K25/00
Filed: 1981-10-06
Abstract: PURPOSE:To avoid starting dead center and to facilitate the winding of a coil on a core by a method wherein a projection section is provided at the tip section of the core in the rotary direction of an armature and a commutator is provided at a rotor. CONSTITUTION:The polarity of an armature 18 is converted in the direction energizing the rotation of the armature 18 by the action of a commutator 22 during rotating the armature 18. However, the core 14 of the armature 18 stops at the position corresponding to the poles of a stator 10 if the power is turned off. When starting is further done and with a current supplied, a magnetic path is deviated in the rotary direction of the armature 18 by the influence of the projection section 16 of the core 14. Therefore, starting is begun by avoiding dead center. In the case of a contactless system using a hall device or the like for position detection, a permanent magnet ring 32 and the armature 18 may be used as a rotor and a stator respectively.

IPC: H04L7/04
Filed: 1993-06-07
Abstract: PURPOSE:To provide a phase controller capable of detecting stably a frequency offset value independently of the reception state. CONSTITUTION:The phase controller having a frequency offset detection means 7 detecting a frequency offset value based on phase information of a received known symbol is provided with a power detection means 9 for detecting a power of the received known symbol, and a selection means 10 which selects a frequency offset value detected by the frequency offset detection means 7 as a phase control output based on the phase information of the received known symbol when the detected power is within the range of a setting value and selectes a frequency offset value outputted precedingly as a phase control output when the power is outside the range of the setting value. When the power of the received known symbol is deviated from the range of the setting value, since it is estimated that the reception state is bad, the frequency offset is not revised, and it is revised only when the power of the known symbol is within the setting value.
