Title: Optical branching device and optical disk device
Inventor: NISHIWAKI SEIJI
IPC: G11B7/09
Filed: 1993-06-18
Abstract: PURPOSE:To provide an optical branching device with simple constitution and effective in branching a beam, and to provide a new optical disk device applying it. CONSTITUTION:When a laser beam 4 is incident on a grating coupler 3A at a proper angle, a waveguide beam 5 with a mode corresponding to an incident angle is excited. Although the waveguide beam 5 is the beam with a single mode, a waveguide mode is disturbed by passing through a step structure 2S, and the waveguide beam 5 becomes the waveguide beam 6 where several modes coexist. Although the waveguide beams 6 (6a, 6b) are radiated from a linear grating coupler 3B for output, a radiation angle depends on the waveguide mode, and the waveguide beams 6 (6a, 6b) are radiated at angles for respective waveguide modes. That is, the waveguide beam 6a with 0-order mode is outputted as a radiation beam 7a with the large radiation angle, and the waveguide beam 6b with 1st-order mode is outputted as the radiation beam 7b with the small radiation angle.

Title: Disk reproducing device
Inventor: OKANO KAZUNORI
IPC: G11B20/10
Filed: 1995-06-14
Abstract: PURPOSE: To obtain a disk reproducing device of reduced power consumption. CONSTITUTION: After reproduction operation, double-speed reproduction and reproduction pause are alternately repeated, thus storing audio data which are constantly equal to or more than a certain amount in a DRAM 12 for preventing sound jump. Audio data are continuously read from the DRAM 12 at a standard speed and a reproduction audio signal is obtained at an output terminal 14. When the alternate operation of the double-speed reproduction and reproduction pause continues for a specific time, a state for continuously performing standard-speed reproduction is automatically initiated by the control of the microcomputer 20. In this case, the amount of data stored in the DRAM 12 is retained to be at a constant value. When the servo-lock state is disabled in the standard-speed reproduction, an intermittent operation of the double-speed reproduction above is initiated.  When a state where the double-speed reproduction and reproduction pause are alternately performed (a motor 2 constantly rotates at the double speed of the standard rotary speed) continues for a specific amount of time, the standard-speed reproduction where the motor 2 rotates at a standard speed is initiated, thus reducing power consumption.

Title: Excitation control device for rotary machine
Inventor: YAMADA TSUTOMU
IPC: H02P9/14
Filed: 1979-11-14
Abstract: PURPOSE:To contribute to the voltage recovery function of a system to the limit of the capacity of a generator by allowing the excessive excitation state during the time period inversely proportional to the magnitude of a field current. CONSTITUTION:A subtractor 16 is operated to subtract a signal equal to the square of the rated field current form a signal doubled by the field current. An operational amplifier 14 squares the deviation signal between the field current and the allowable field current. If the field current becomes higher than the allowable field current, a relay 11 is energized, to cause the contact 11b to be closed. Thus, an operational amplifier 21 integrates the signal added with the outputs from the subtractor 16 and the amplifier 14. If the output of the operational amplifier 21 exceeds the set value, a relay 24 is energized to cause the contact 24a to be closed, and the deviation signal is supplied as an excessive excitation limit signal to an automatic voltage regulator 4. Thus, the voltage recovery of the system can be contributed up to the limit of the capacity of the generator.
