Data transferred from a host computer to a memory device is written into sectors whose addresses in a memory area are decoded by a decode table. Old data to be updated by the above data is erased or marked with erase flags. At a predetermined point of time, in order to create free areas, necessary data is evacuated to a primary memory media and unnecessary data indicated by erase flags is erased by a unit of predetermined memory size. Part of the memory media which has become defective is marked with a defect flag, and is replaced by an alternate area. In doing so, the decode table is rewritten to arrange the memory area.

A double-cavity half-toroidal type continuously variable transmission comprises an input shaft rotatable by means of a drive source, first and second input disks rotatable integrally with the input shaft, first and second output disks opposed to corresponding input disks, and a hydraulic loading mechanism. The hydraulic loading mechanism includes first and second hydraulic chambers arranged in the axial direction of the input shaft. The first hydraulic chamber is defined by the back surface of the first input disk, an end face of the first disk member, etc. The second hydraulic chamber is defined by the inner end face of the first cylinder, an end face of the second disk member, etc. The first and second hydraulic chambers are simultaneously supplied with pressurized oil by means of a pressure source. Under the pressure of the oil, the first input disk is pressed toward the first output disk, and the second input disk is pressed toward the second output disk through the medium of an interlocking portion.

A moving apparatus with a driving force assist mechanism traveled mainly by human power. This moving apparatus detects, in a non-contact manner, with respect to rotating portion such as traveling wheel, etc., rotation speed of the rotating portion to detect traveling state to deliver, from the driving force assist mechanism, assistant driving force corresponding to speed change information that a person who operates the moving apparatus intends to give on the basis of the detected traveling information to carry out traveling to thereby permit smooth traveling even in the case where traveling by only human power becomes difficult.

In the toroidal type continuously variable transmission system 100 incorporating a power roller bearing 11 therein, race grooves 15 and 16 respectively formed in the inner and outer races 35 and 13 of the power roller bearing 11 are respectively structured in such a manner as to have an arc-shaped cross section, and the radii of curvatures of the arc-shaped cross sections of race grooves 15 and 16 are set in the range of 52% to 59% of diameter of a rolling ball body which can roll on these race grooves, thereby being able not only to restrict an increase in dynamic torque of the power roller bearing but also to improve life of the power roller bearing.

The toroidal-type continuously variable transmission includes an input disk, an output disk disposed coaxially with the input disk, a trunnion capable of swinging about its pivot shaft portion situated at a torsional relation with respect to the respective center axes of the input and output disks; and a power roller supported on the trunnion and inclinably rollable on and between the input and output disks. The trunnion includes a main body plane portion for holding a displacement shaft supporting the power roller rotatably and a pair of pivot shaft portions respectively formed in the two end portions of the main body plane portion integrally therewith, while two connecting portions respectively between the main body plane portion and the pair of pivot shaft portions are respectively formed so as to include continuous metal flows.

An electron beam drawing process of high throughput, coping with the changes in static distortion and dynamic distortion of a lower layer exposure apparatus or an optical reduction exposure apparatus. At least two marks formed in each chip formed on a wafer are detected for a predetermined number of chips, and the relation between the shape distortion of each chip in the wafer plane and the wafer coordinates is determined from the positions of the detected marks and the designed positions of the marks by a statistical processing. Patterns are drawn in all chips while correcting the patterns to be drawn on the individual chips, by using the relation between the determined chip shape distortion and the wafer coordinates. As a result, the superposition exposure with the lower layer can be with a high throughput and with a high accuracy without any manual adjustment.

摘要:
A load applied to the constituent member of a toroidal type continuously variable transmission is mitigated to thereby improve the durability thereof. During low speed running, a clutch for low speed is connected and a clutch for high speed and a clutch for backward movement are disconnected. During high speed running, the clutch for high speed is connected and the clutch for low speed and the clutch for backward movement are disconnected. During the high speed running, a torque is applied to the output side disc of the toroidal type continuously variable transmission. This torque becomes smaller as the transmission ratio as a whole is displaced to the high speed side. Correspondingly thereto, the load applied to the constituent member of the toroidal type continuously variable transmission can be mitigated.

A semiconductor device may include a double hetero junction bipolar transistor and a field-effect transistor. The base of the bipolar transistor and the gate of the field-effect transistor are connected to each other to serve as an input terminal and the collector of the bipolar transistor and the drain of the field-effect transistor are connected to each other to serve as an output terminal. The bipolar transistor and the field-effect transistor may be created on a common substrate. In this case, both the bipolar and field-effect transistors can have the same multilayer/film structures.
