Title: Valve driving device of engine
Inventor: KAWAMURA HIDEO
IPC: F01L9/04
Filed: 1991-08-20
Abstract: PURPOSE:To make valve opening timing accurate by making valve opening and closing force regulatable, and also to prolong a service life of the valve and to improve wear resistivity of a rocking body by making the valve come in contact with the valve seat softly. CONSTITUTION:A valve 1 is provided with a rocking body 4 integratedly. Force for opening and closing the valve 1 can be regulated by controlling the magnitude of the force caused by the relationship between the magnetic flux generated by a fixed coil 8 and the regulated electric current in the moving conductor wire 6 of the rocking body 4. In such a way, strong force is output during the early stage of the valve motion by controlling the magnitude of the opening and closing force of the valve 1. When the valve 1 is going to come in contact with the valve seat, braking force makes the contact of the valve soft. Accordingly, wear of the valve 1 is reduced. In addition, it is possible to prolong the service life of the whole valve driving device by using the wear resistive material, which is impregnated with Aluminum in porous material, in the sliding portion of the brush of the rocking body 4.

Filed: 1988-09-20
Abstract: PURPOSE:To attain the loopback test of a signal having a delay time taking timing into account by providing a delay circuit and a loopback circuit to a data terminal equipment(DTE). CONSTITUTION:In the case of conducting a loopback test, that is, a loop test in a data terminal equipment, an SEL signal is brought into an H level. An output of a delay signal generating circuit 20 is applied to other input of selectors 16-19, the selector selects an output of the delay signal generating circuit 20 respectively and applies it to a host computer. An HRS signal and an HER signal from the host computer are applied to the delay signal generating circuit 20, and a signal retarded by a specific time for example, is generated from the two signals and fed to the selectors 16-19. Since a delay in the delay signal generating circuit 20 is used in this way, the signal is reflected not by simple signal loopback but by loopback as a signal with a delay depending on, e.g., a preset value.

Title: Disk player device
Inventor: YOKOTA HACHIRO
IPC: G11B27/34
Filed: 1992-09-01
Abstract: PURPOSE:To display a track title by eliminating the need of a RAM for a track title incorporated in a system controller or making the capacity of the RAM small. CONSTITUTION:This device is a disk player device provided with a shockproof memory 11. In the case the data recording amount of the memory 11 is between a 1st value approximate to a normal recording amount and a full data value, the recording data of a disk 1 is read at high speed and written in the memory 11. When the data recording amount of the memory 11 attains the full data value, the read of the disk 1 is interrupted until the data recording amount of the memory 11 is lowered to the 1st value or under, and the track title is read out from the disk 1 when the display of the track title is required in the midst of playback. During the above, the data written in the memory 11 is read out and the playback is continued. When the data recording amount of the memory 11 attains the 2nd value equal to or under the 1st value, the high-speed read of the recording data of the disk 1 takes priority over the readout of the track title.
