Filed: 1990-01-29
Abstract: PURPOSE:To enable the centroid drive of both focus actuator and track actuator and to obtain a good characteristic by disposing an optical block of coupling an actuator and a positioner driving coil in between two lines of linear motor magnetic circuits. CONSTITUTION:The optical block 3 and the lens actuator 6 are disposed between one pair of the linear motor magnetic circuits 5 in two lines as a set. Then, an objective lens 9 is positioned in a deviated part from a rotary shaft of the lens actuator, and on both right and left end parts, integrated focus and tracking coils 7 and 8 are disposed respectively in the magnetic circuits for common use with the positioner driving coil 4. Then, by the focus and tracking coils 7 and 8 supported slidably in the linear motor magnetic circuits 5, the objective lens 9 being supported by a hinge mechanism actuator is driven in the focusing direction and tracking direction of the disk. By this method, the centroids of both focus and track actuators 6 are driven, and moreover shock resistance and acceleration resistance are superior, and hence the good characteristic optical head is thus obtained.

Title: Underground buried object probe
Inventor: WATANABE YASUSHI
IPC: G01S13/88
Filed: 1986-01-30
Abstract: PURPOSE:To enable a rapid measurement to be conducted by providing a circuit for feeding hold signals to a plurality of sample hold circuits and a circuit for sequentially changing over the output from the sample hold circuits after enlargement for a prescribed necessary time. CONSTITUTION:A synchronous circuit 12, in synchronism with trigger pulses, sequentially feeds hold signals from sample hold circuits 13a-13n at intervals DELTAt. An output changeover circuit 14 sequentially changes over the sample hold outputs from the sample hold circuits 13a-13n every given time. Then, since the holds of all the sample hold circuits are completed by the reflection echo produced by one transmission, a reproduction at any frequency is enabled without depending on a repetitive period. Thus, when an output changeover time interval is taken equal to 9repetitive period + DELTAt), the output waveform equal to that of an sampling output can be reproduced by one reception echo and, even when the number of samplings is very large or the repetitive period is very long, the waveform converted to a low frequency can be reproduced at a given frequency.

Title: Freezing cycle device
Inventor: TAKANO YOSHIAKI
IPC: F25B1/00
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To prevent the stay phenomena of a refrigerant in a refrigerant pipe at hot gas bypass operation. SOLUTION: A check valve 16 is built in the joint 151 of an expansion valve 15 of a temperature type for depressurizing the refrigerant condensed in a condenser, and a bypass connection port 165 where the outlet of a hot gas bypass passage is to be connected is opened downstream of this check valve 16. This prevents the refrigerant from the hot gas bypass passage from flowing reversely to the upstream of the expansion valve 15. Since the bypass connection port 165 and the check valve 16 can be arranged adjacently, this freezing cycle device can favorably prevent the occurrence of such phenomena that the discharged gas refrigerant flows in a refrigerant pipe upstream of the expansion valve 15 and stays there at hot gas bypass operation.
