An object of the invention is to, in a vehicular alternating current (AC) dynamo, reduce an influence of vibration on a brush during operation, thereby preventing the brush from wobbling, cracking or causing other damages, also to make the brush sufficiently exposed to cooling air during operation, thereby preventing the brush temperature from rising excessively. In the vehicular AC dynamo, by virtue of a pressing force produced upon a tubular cover integral with a fan guide being fixed to a rear bracket through a seal member, an abutting end surface of a projection of the tubular cover is axially abutted with an inner abutting surface of a recess of the brush holder for pressing and fixing said brush holder against and to the rear bracket. In addition, the side of the fan guide and the side of the brush holder are arranged to be flush with each other, and a labyrinth seal structure is constituted by a circumferential groove of an end flange and a cylindrical projection which is formed by both the tubular cover and the brush holder.

A strut mount allows a sufficient pre-compression to be applied to a rubber member without impairing the retaining force for the rubber member, thereby achieving improved durability of the rubber member. A pre-compression member (4) has an outer diameter that is smaller in the distal end side than in the proximal end side, and is press-fitted into the inner peripheral surface of an inner tube member (1).

A process of making a chlorinated hydrocarbon through a thermal dehydrochlorination step in which an unsaturated compound represented by the following general formula (2) is obtained by thermally decomposing a saturated compound represented by the following general formula (1). CCl3—CCl2-mHm—CCl3-nHn (1) CCl2═CCl2-mHm-1—CCl3-nHn (2) (in the above formulas, m is 1 or 2, and n is an integer of 0 to 3.).

A slide action type hinged-lid package (2) includes an inner case (6) having a lid (4), and an outer body (8) slidably accommodating the inner case. The outer body has an opening (46) formed through a front wall thereof (40) and allowing the inner case to be partly exposed, and a contact piece (48) provided at the rear edge of an upper open end thereof (38) and extending toward the interior of the outer body. The inner case has a reinforcing member arranged on the inside of a front wall thereof (14) which is exposed through the opening, and a strip (34) connected to the rear part of the lid and capable of engaging with the contact piece. When the inner case is slid up relative to the outer body, the engagement between the strip and the contact piece causes the lid to open and also regulates the amount of sliding of the inner case.

An auto laser power control circuit is provided which improves the response of the optical output level of a laser diode in accordance with variations in the operation mode. In an auto laser power control circuit for comparing a voltage corresponding to the optical output from the laser diode which emits a light in accordance with a supplied driving current with a reference voltage, and controlling the driving current so as to reduce the difference at the time of the steady operation, by controlling a switch connected between the input and output terminals of an operational unit which compares the voltage corresponding to the optical output from the laser diode and the reference voltage, the driving current to the laser diode is controlled with a smaller time constant upon the start such as a transition of from a read operation mode to a write operation mode as compared with the time of the steady operation.

A vehicle alternator output rectifier instrument in which mesa structure Zener diodes, formed by diffusion of impurity on a P-type silicon substrate, are used as rectifier elements which are used in rectifier circuits for rectifying an alternate current output of a vehicle alternator. Since the vehicle alternator output rectifier instrument employs the above Zener diodes, this rectifier instrument can endure high temperature circumstances, considerably reduce a reverse leakage current to thereby prevent a battery voltage from being discharged and reduce a radio noise to thereby reduce a bad influence exerted upon an electronic device serving as a load.

Glycidyl (meth)-acrylate polymer and an organic acid, phosphoric acid, phosphorous acid, hypophosphoric acid and/or a compound other than an organic acid containing one or more functional groups selected from among carboxyl, amino, hydroxyl, acid anhydride and thiol groups added to an aromatic polycarbonate resin composition, decrease the luster of the composition without compromising the properties of the composition.
摘要:
A laser printer comprises a cartridge of a photosensitive unit, a printing mechanism for effecting a printing operation by electrifying a photosensitive member of the photosensitive unit, applying a light beam to the electrified photosensitive member to form an electrostatic latent image thereon, developing the electrostatic latent image to create a visible image and then transferring the image to printing paper, and a nonvolatile memory for storing data indicating the printing history of the photosensitive unit. The printing device further comprises a microprocessor for updating the data stored in the nonvolatile memory each time the printing operation is effected, checking whether the data stored in the nonvolatile memory has reached a value corresponding to a service life of the photosensitive unit, and generating a replacement requiring signal when it is detected that the data stored in the nonvolatile memory has reached the value.

There is disclosed a rectifier assembly for an AC generator for use with vehicles. The rectifier assembly comprises a single horseshoe heat radiating plate and electric circuit elements mounted thereon, and including at least one rectifier unit and two DC output conductor plates. The two d.c. output conductor plates are disposed in spaced relationship on one surface of the heat radiating plate with an intermediate insulating layer and electrically connected to output terminals of the rectifier unit. The assembly may be incorporated with a voltage regulator of an integrated circuit configuration for controlling the output voltage of the AC generator and a brush holder. The voltage regulator may be coplanar with the conductor plates.
