A motor used in a power window system includes a motor section, a warm-gear included output section and a one-way clutch. The one-way clutch is disposed between a motor's shaft and a worm's shaft. The one-way clutch includes a drive member having at least a pair of guide surfaces, driven member coupled with the drive member, a stationary housing, and a rotary member disposed between the driven member and the stationary member and between the pair of guide surfaces. The motor and the one-way clutch has a common member fixed to both the motor and the one-way clutch.

A linearly polarized light beam emitted from a coherent light source reaches a polarizing phase plate and is thereby divided into a primary beam and a subsidiary beam having a polarized light component perpendicular to the polarized light component of the primary beam and a double-humped pattern, in which the center position coincides with the center position of the primary beam and the principal portion is equal in size to the principal portion of the primary beam. The primary beam and the subsidiary beam are focused onto an information storage surface of an optical disk and reflected therefrom, so that they are separated again through polarization separation and individually detected by first to third optical detectors. The output signals from the first to third optical detectors are calculated by a differential calculator and outputted therefrom.

A paint film laminate is co-molded over a desired plastic substrate to produce an automobile bumper member, chin spoiler or rocker panel part. Along a desired surface of the part, such as, for example, a border between a part surface having one segment covered by paint film and a second segment comprising the exposed substrate, the edge of the paint film is embedded in the plastic substrate along a surface discontinuity such as a recess or ridge so that an aesthetically pleasing sight edge having a desired contour exists along this surface portion. The sight edge is formed during the co-molding process via the provision of an incline or ramp along a desired mold cavity surface. When the co-molded part is installed in its intended application, the paint film edge is substantially hidden from view by the surface discontinuity.

A transmission and reception system for controlling a locking/unlocking operation of a key includes a transmission section for transmitting a control signal having a predetermined frequency for effecting locking/unlocking of the key, and a reception section for receiving the control signal and effecting driving control of the key in response to the control signal. The reception section includes a carrier detection circuit for detecting a frequency of the control signal and supplies power only to the carrier detection circuit when the control signal is not received.

Improved methods of superposing a film laminate over a plastic substrate and fused film-plastic parts made thereby. Improvement in traditional techniques is provided by preforming the film laminate proportionately relative to the size and shape of the underlying plastic substrate whereby improved gloss consistency of the fused film-plastic part is observed. The film laminate is preformed by shaping it over a pattern block wherein the film laminate is provided with an inner height and inner face width. The inner height of the film laminate is less than the height of the plastic substrate while the inner face width of the film laminate is greater than the face width of the plastic substrate. The film laminate is next positioned in a mold cavity wherein a molten resin is injected thereby forming the plastic substrate and fusing the film laminate thereover.

A light beam emitted from a semiconductor laser element is collimated by a collimating lens, and is applied to an optical disk through a polarizing holographic beam splitter, a .lambda./4 plate and an objective lens, a light beam reflected by the optical disk is applied to the polarizing holographic beam splitter and is diffracted. Diffracted light beams of +1st order and -1st order are applied to two photodetectors, and a focus error signal and a tracking error signal are obtained on the basis of the diffracted light beam of +1st order and an information signal is obtained on the basis of the diffracted light beam of -1st order.

A fusion protein comprising a carrier and a desired peptide or protein linked to the carrier via an enzymatically excisable dipeptide, such as Lys-Arg, is produced in a host microorganism and then the desired peptide or protein is recovered by treating the fusion protein at least with a protease specifically recognizing the dipeptide and specifically hydrolyzing the peptide bond of the dipeptide. The fusion protein includes tandem-form fusion proteins in which desired peptide or protein molecules are linked together repeatedly. According to the cleavage site in the dipeptide, the protease may be used in combination with an aminopeptidase specifically releasing a basic amino acid from the N-terminal side of the dipeptide and/or a carboxypeptidase specifically releasing a basic amino acid from the C-terminal side of the dipeptide.

An optical element includes a crystal of LiTa.sub.X Nb.sub.1-X O.sub.3 which has one of an x-surface and a y-surface, where X denotes an atomic fraction and 0.ltoreq.X.ltoreq.1. Proton-exchanged layers periodically extend on one of the x-surface and the y-surface of the crystal. Grooves extend in said one of the x-surface and the y-surface of the crystal, and have bottoms which are defined by surfaces of the proton-exchanged layers. Ordinary light which has passed through the proton-exchanged layers and the grooves is out of phase with respect to ordinary light which has passed through a region of the crystal outside the proton-exchanged layers and the grooves by a quantity of (2n+1).pi., where n denotes an arbitrary integer. Extraordinary light which has passed through the proton-exchanged layers and the grooves is out of phase with respect to extraordinary light which has passed through a region of the crystal outside the proton-exchanged layers and the grooves by a quantity of 2 m.pi., where m denotes an arbitrary integer.

The wavelength tolerance of a frequency doubler is enhanced so as to perform stable operation. Further, with the use of this frequency doubler, a laser source can directly modulate a laser. A waveguide and a periodic domain inverted layer are formed on an LiTaO.sub.3 substrate of -C plate, and the waveguide is divided into a plurality of zones having different propagation constants. A fundamental wave inputted in the waveguide is converted into a harmonic wave in each of the zones, and is emitted as SHG light. Parts for modulating the phases of the harmonic waves produced in the respective zones are provided between the zones.

An apparatus for controlling a continuously variable vehicle transmission includes a fixed pulley member and a movable pulley member which is supported for movement toward and away from the fixed pulley member. A groove defined between the pulley members has a width which is decreased and increased to thereby respectively increase and decrease the rotational radius of a belt which is received in the groove. A control arrangement executes speed change control to change the belt ratio. The control arrangement includes a control unit which receives throttle opening degree and vehicle velocity detection signals and determines first and second target engine rotational speed which are based respectively on these detection signals. The control unit determines an optimum target engine rotational speed based on the firt and second target engine rotational speeds and sets upper and lower limit values of the optimum target engine rotational speed in accordance with predetermined conditions. The control unit processes the optimum target engine rotational speed to obtain a final target engine rotational speed which is used to control the transmission.
