摘要:
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.

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.

A head-up display system for a vehicle includes a front windshield, a display, a polarizing member and an optical rotatory film. The display for displaying an image on the front windshield to be viewed by a driver of the vehicle is disposed such that light therefrom is incident on the front windshield at an angle which is substantially equal to Brewster's angle. The polarizing member is disposed between the front windshield and the display for polarizing light from the display. The optical rotatory film serves to rotate the plane of polarization of light polarized by the polarizing member. The optical rotatory film installed on the front windshield includes a liquid crystal high polymer which is in twisted nematic orientation under liquid crystal condition and is in glassy condition at a temperature which is lower than liquid crystal transition point. Thus, double image problem can be eliminated with respect to light having a wide range of wavelengths.

The present invention relates to a freshness retentive for cut flowers, which comprises a mixture of a silver compound and a primary amine and/or a nucleic acid-related substance and/or reaction products thereof. The silver compound is silver nitrate, silver acetate or silver phosphate; the primary amine is methylamine, ethylamine, monoethanolamine, tris(hydroxymethyl)aminomethane, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-ethyl-1,3-propanediol, .alpha.-aminooxyacetic acid or aminoethoxyvinylglycine; and the nucleic acid-related substance is nucleic base, nucleoside, nucleotide, oligonucleotide, polynucleotide, purine derivative or pyrimidine derivative.The present freshness retentive for cut flowers demonstrates an extremely excellent effect on cut flowers highly sensitive to ethylene, e.g. carnation, Gypsophila elegans, sweet pea, etc., as well as on cut flowers low sensitive to ethylene, e.g. chrysanthemum, rose, orchid, etc., for their freshness retention.
摘要:
An electron beam writing system which permits a relatively low voltage to be applied to perform high speed focus correction with high accuracy. The electron beam writing system includes a focus corrector arranged inside a lens which provides the largest product of the magnification factors of the lens and all succeeding lenses and the optical path length of the lens at issue. Thus, the electron beam provides high sensitivity and a small change in the magnification ratio due to the correction.
摘要:
In a high speed logic circuit using a vertical hetero-junction bipolar transistor, in which two-dimensional carriers formed at a semiconductor hetero-junction interface are used as a base layer, the uppermost layer being a collector layer, the lowest layer being an emitter layer, two base electrodes making contact with the base layer are disposed so as to put a collector electrode, which is electrically in contact with the collector layer, therebetween. The base electrodes are used at the same time as a source electrode and a drain electrode, respectively, of a field effect transistor using the two-dimensional carriers as an active layer. The high speed logic circuit is so constructed that one of the base electrodes of the bipolar transistor is an input terminal; the other is connected with a power supply; the emitter is grounded; and the collector is an output terminal.
