    • A method of producing a plurality of masks which are used when ROM type data are written in an optical recording medium for ROM type optical recording cards. The method is practiced by way of steps of producing a mother mask having a preformatting pattern, next, transcribing the preformatting pattern for the mother mask, next, producing a master mask having a required optical recording pattern written therein and next, producing a working mask from the master mask. When the preformatting pattern is prepared in a writable type, writing or inspecting of the master mask or inspecting of the working mask or mother mask can be achieved using a writing/reading apparatus for writable type optical recording cards.

    • In an optical card, a card substrate has its rigidity which is sufficient to handle the card substrate independently. The card substrate has a first side which serves as a reading side upon which reading light is incident. An optical-data recording section includes a light-reflective pattern. The optical-data recording section is arranged on one of the first and second sides of the card substrate. Optical data incident upon the optical-data recording section toward the reading side of the card substrate is recorded by the optical-data recording section. A shielding layer is arranged on one of the first and second sides of the card substrate, for shielding the optical-data recording section from a viewer's field of view. The shielding layer has its transmission characteristic with respect to the reading light, which is sufficient to shield light within a visual range and to enable reading of the optical-data recording section.
    • 在光卡中,卡片基板(30; 212; 312)具有足以独立地处理卡片基板的刚性。 卡片基板具有用作读取光入射的读取侧的第一侧(30a; 212a; 312a)。 光学数据记录部分(70; 270; 370)包括光反射图案(42; 214; 314)。 光学数据记录部分布置在卡片基板的第一和第二侧中的一个上。 通过光学数据记录部分记录在光学数据记录部分朝向卡片基板的读取侧的光学数据。 屏蔽层(34; 216; 316)布置在卡片基板的第一和第二侧之一上,用于屏蔽光学数据记录部分不受观察者的视场影响。 屏蔽层相对于读取光具有其传输特性,其足以将光屏蔽在视觉范围内并且能够读取光学数据记录部分。

    • A disk cartridge comprises a cartridge casing having a head entry aperture, a disk recording medium rotatably accommodated in the cartridge casing, a shutter for opening/closing the head entry aperture, and a spring member for resiliently biasing the shutter in the closing direction. The spring member includes a proximal end portion engaged with the cartridge casing, a resilient end portion engaged with the shutter, and an intermediate engaging portion provided between the proximal end portion and the resilient end portion, a displacement-preventing portion is provided in an area where the intermediate engaging portion is passed upon an opening/closing operation of the shutter, and the intermediate engaging portion is adapted to be brought into contact with the displacement-preventing portion, thereby canceling a force of the spring member to spring out or fall in, and enabling to enhance reliability.

    • Several embodiments of vehicles having automatic or manual speed control. The manual speed control permits the operator to control the speed of the engine and the automatic speed control is effective when a power takeoff shaft is being driven for automatic speed control under this condition. In each embodiment, the automatic speed control includes a governor that is driven only when the power shaft takeoff is being driven. In one embodiment, a throttle valve controls the engine speed and the manual and automatic speed controls alternatively operate the throttle valve through selectively engageable couplings that are operated in response to shifting into and out of the power takeoff mode. A number of other arrangements are also illustrated and described that provide different throttle valve arrangements for controlling the speed automatically or manually.
