Title: Polarization transforming optical system
Inventor: TAKANASHI RYOYU
IPC: G02F1/13
Filed: 1990-05-18
Abstract: PURPOSE:To obtain a high illuminance characteristic having high efficiency for utilizing beams without varying the illuminance characteristic by emitting a linearly polarized beam composed of almost one series of S polarized beams or P polarized beams mixed and synthesized by plural mirrors. CONSTITUTION:The first S polarized beam is reflected on the side of a mirror face 4a1 of a mirror face 4a and the second S polarized beam is reflected on the side of a mirror face 4a2. These first and second S polarized beams are mixed and synthesized so as to obtain the linearly polarized beam of almost one series of S polarized beams composed of parallel light flux. Since this third S polarized beam mixes and synthesizes the beams, it becomes the almost uniform linearly polarized beam. On the other hand, from indefinitely polarized beams from a light source, the linearly polarized beam of the mixed and synthesized S or P polarized beams composed of the parallel light flux is obtained by using a single polarized beam splitter 1 without using plural polarized beam splitters. Thus, the high illuminance characteristic having the high efficiency for utilizing beams can be obtained without varying the illuminance characteristic.

Title: Centrifuge
Inventor: NAGATA AKIO
IPC: B04B15/02
Filed: 1980-09-17
Abstract: PURPOSE: To enhance the accuracy of temperature control and to enable high- accuracy separation, by putting a freezer into an ON state with proper use of a device for generating an ON-OFF signal on the basis of the magnitude of a rotor temperature-detecting signal and another device for generating an ON-OFF signal having predetermined time intervals.  
     CONSTITUTION: When an ON-OFF signal (a) on the basis of a temperature-detecting signal 21 is at an ON level, a heater relay turns into ON to put a heater into an ON state. When the signal is at an OFF level, an output from an inverter 24 turns into an On level. When an ON-OFF signal (b) from a freezer relay signal-generating circuit 28 is at an ON level, a freezer relay turns into ON to put a freezer into an ON state. Therefore, if the ON and OFF periods of the freezer are preset so as to minimize the temperature gradient of a rotor, the duration while the freezer is ON is shortened. Consequently, the freezer works as if it were miniaturized in volume. As a result, a temperature fluctuation in relation to the preset temperature of the rotor becomes small, and high-accuracy centrifugal separation can be done.

Title: Opening and closing device
Inventor: ASANO HIDEO
IPC: B60H1/00
Filed: 1994-06-13
Abstract: PURPOSE:To keep fluid leaking to a minimum when each passing through hole is blocked by providing the device with a movable membrane shaped member equipped with an opening section capable of opening each passing through hole, and with an operating means moving the membrane shaped member in a sate that the aforesaid member is faced to each passing through hole, and concurrently providing each lattice for the passing through holes. CONSTITUTION:The setting of a blow-off mode section lever to a ventilation blow-off mode position permits a drive plate 50 to be driven by a wire, allows a ventilation blow-off port to be fully opened by a first opening section 25, and consequently allows a defroster blow-off port 12 and a heater flow-off port 14 to be fully blocked by a film damper 20. Since each lattice 22 and 24 is provided in the insides of the openings of the defroster blow-off port 12 and the heater blow-off port 14, the film damper 20 is thereby kept small from swelling outward. Therefore the film damper 20 is kept small from being deflected, and air can thereby be kept small from leaking when both the blow- off ports 12 and 14 are blocked.

Title: Feed servo circuit for optical disc reproducing device
Inventor: MAEDA SATORU
IPC: G11B7/085
Filed: 1985-06-17
Abstract: PURPOSE:To attain feed servo operation with low power consumption by using a drive signal to drive a feed control device to apply moving control to an optical pickup in the radial direction of a disc in a way that the DC component produced in a tracking servo circuit is decreased. CONSTITUTION:The DC component of an output signal V22 of a low-pass filter 22 is increased in response to changes in a displacement X of a tracking actuator 21 and since a feed servo switch 27 is turned on only when a feed servo control signal FC is at a high level, the control signal is fed intermittently to a feed motor drive circuit 23 for a prescribed time at a prescribed period and the feed motor drive signal FC is fed to a feed motor 24. When a drive signal having a sufficient voltage level is given to the feed motor 24, the motor 24 is driven at points of time t1, t2 to apply moving control to the pickup 12. Since the feed servo circuit applies intermittently the drive signal to the feed motor 24, no power is consumed during pause period and the power efficiency is increased. Thus, the feed servo operation is attained with low power consumption.
