摘要:
A moving-coil type pickup cartridge comprises a vibration system including a stylus for tracing a sound groove of a record disc, at least one coil plate adapted to vibrate in response to vibration of the stylus of the vibration system, and an arrangement for producing magnetic fields with respect to the coil plate. The coil plate has at least one coil formed by thin film in a spirally-shaped pattern. The magnetic field producing arrangement has at least one permanent magnet for producing magnetic fields wherein are produced magnetic fluxes of mutually opposite directions respectively in regions of the coil resulting from substantially halving of the coil in the vibration direction thereof.

A moving-coil type pickup cartridge comprising a cantilever provided at the free end thereof with a stylus for tracing a sound groove of a record disc, a coil plate provided on the cantilever in a manner to vibrate in response to vibration of the stylus, and an arrangement for producing an effective magnetic field within a specific gap. The coil plate comprises a thin electrically insulating base plate and at least one coil which is formed from a thin film in a spirally-shaped pattern on at least one surface of the base plate. The coil plate has at least one upright part formed by bending the base plate together with a portion of the coil and interposed in a freely vibratory manner within said gap of the magnetic field producing arrangement and a mounting part integrally joined to the upright part and fixed to the cantilever.

A signal-pickup cartridge is adapted to be loaded into a holder of a signal-pickup device proper of a rotating recording medium reproducing apparatus. The signal-pickup cartridge comprises a cantilever having at its distal tip a reproducing element for picking up and reproducing a signal from a rotating recording medium rotating in the apparatus, a cartridge case supporting therewithin the cantilever and having a ceiling plate and vertical walls on opposite sides thereof, a box-shaped cover joinable to the cartridge case to cover the lower face thereof in a manner to protect the cantilever and the reproducing element, and a mechanism for joining the cover and the case in latched state. This mechanism is triggered to unlatch the cover from the case when the cartridge is inserted into the holder.

A signal pickup device in a rotary recording medium reproducing apparatus, comprises a cantilever provided with a reproducing element for picking up and reproducing a signal from a rotary recording medium at the tip end thereof, a support member having a support part for supporting the rear end part of the cantilever, and arms which unitarily extend on both sides from the support part, and a frame having engaging parts engaged with and mounted with the arms of the support member, for holding the arms. The arms of the support member respectively are provided with mounting parts having non-circular cross-section in the vicinity of the end part thereof, for engaging with the engaging parts of the frame. Moreover, the mounting parts and the engaging parts are shaped so that the support member is at an angular position together with the cantilever where the reproducing element is at a raised position, when the mounting parts are mounted onto the engaging parts.

The part lifetime management system includes a parts server and a parts lifetime managing server. Parts server stores various data of parts used to repair car, automobile, etc. When the drawing of a repair part is released, future integration plan of the part is decided and inputted to the parts lifetime managing server with an integration condition. In the future, when the integration condition is satisfied, the parts lifetime managing server outputs the instruction to integrate a part to predetermined terminal. Then, the supply of a pre-integration part is stopped and changed to post-integration part so that the number of kinds of repair parts are reduced.

A pickup cartridge comprising a cantilever and a stylus attached to the free end of the cantilever. The cantilever is formed with a flat portion and a ribbed portion extending along the length of the flat portion so that the transverse cross-section of the cantilever is of a cruciform configuration. The flat and ribbed portions are dimensioned so that the cantilever tends to oscillate at a frequency different from the resonant frequencies of disc records.

In the present invention, by the method using a backing material such as copper, which is not melted by a welding heat source, in an end face of a member without using a backing metal or consumable backing material at a joint welding time, overlay welding is performed to increase a plate thickness and a plate width. Thereafter, edge preparation including a member of a designed joint weld location and an overlay weld is performed, and the groove processed portion is placed to an opponent member to provide joint welding in order to obtain an effective throat depth more than a plate thickness and a plate width of the member.
