Title: Recording disc cleaner
Inventor: OOTSUKI TOSHIO
IPC: G11B3/58
Filed: 1977-12-27
Abstract: PURPOSE:To perfectly remove the dust having deposited on modulated grooves by a simple method by so disposing a support shaft that a part of record disc except its label is dipped in the liquid in an ultrasonic cleaning bath and cleaning the record disc while letting the same rotate. CONSTITUTION:A record disc support shaft 7 which supports a record disc 8 by passing through its central hole is rotatably engaged at its both end parts in the nothces 6a of the support plate 6 provided to an ultrasonic cleaning bath and is provided with a groove 7a which defines the movement in the axial direction. The record disc 8 is supported approximately perpendicularly with respect to the shaft 7 by the auxiliary plate 9 fixed to the support shaft 7. The support plate 6 provided in the opening part of the cleaning bath 1 is set at such a height that when the support shaft 7 is mounted a part of the record disc 8 dips in the cleaning liquid surface in the cleaning bath 1 but the label 10 affixed to the central part does not dip in the cleaning liquid surface. Hence, if the cleaning bath 1 is operated while the record disc 8 is being rotated, the dust having been deposited in the minute modulated grooves may be readily and perfectly removed.

Filed: 1989-06-19
Abstract: PURPOSE:To improve number of repetitive erasure times and the heat resistance by providing a thermal expansion layer made of an organic dystuff and a binder onto a transparent base and providing a shape keeping layer made of a low melting point metal on the expansion layer. CONSTITUTION:The thermal expansion layer 12 made of an organic dystuff having an absorbing band in a wavelength of a near infrared-ray and a binder being an amorphous polymer is formed on a transparent base 11. The tin is vapor-deposited on the layer 12 to form a low melting point metallic layer 13. Moreover, a flexible layer 14 and an overcoat layer 15 are formed on the layer 13. In the recording, a laser beam with a medium power level irradiates from the transparent base side so that the focus resides in the vicinity of the border between the layer 12 and the base 11 to heat the layer 12 to be at 150 deg.C or over and at the melting point of the layer 13 or below. Thus, the layer 12 is thermally expanded to lift up the layer 13 to cause plastic deformation, dome shaped pits are formed on the layer 13, resulting that signals are recorded. Through the constitution above, the size of the pits is stable, residual signals left unerased is less at the erasure and the number of repetitive erasure times and the heat resistance are improved.

Abstract: PURPOSE:To eliminate a strong or weak state of air blowing sound and enable an efficient operation to be attained by a method wherein an output from a first differential amplifier and a reference voltage are differentially amplified to generate an output voltage and a second differential amplifier composed with a rate of amplification being variable is provided. CONSTITUTION:A control device for a ventilation fan may differentially amplify through a second differential amplifier 13 having a variable amplification rate G a voltage Vo1 in which a set voltage VS and a detected voltage Yt are differentially amplified with a first differential amplifier 11 and a reference voltage Vr for determining an output voltage at the set temperature, an output voltage Vo corresponding to its value is applied to a ventilation fan 6 so as to control its rotational speed. Accordingly, the output voltage Vo is proportional to a difference between the set temperature and the detected temperature and an amplification rate of the second differential amplifier 13 so as to get an output voltage proportional to the temperature difference. An adjustment of the amplification rate of the second differential amplifier 13 causes an inclination of the output voltage proportional to the temperature difference to be varied. With such an arrangement, the temperature is always kept well and no severe strong or weak air blowing sound is produced and uncomfortable feeling can be avoided and an efficient operation may always be performed.

Filed: 1994-07-08
Abstract: PURPOSE:To improve compressing efficiency by forming an inclined flow passage with its exit located more in a radial outside direction than its entrance between a casing and a rotationally-driven disk and disposing a reverse chamber part in a part of a rotor blade attached to the disk. CONSTITUTION:When a reverse chamber part 41 is disposed on a rotor blade 40, a part of compressed air flows along the projecting surface 42 or the recessed surface 43 of the reverse chamber part 41. When a part of compressed air meanders in the vicinity of the reverse chamber part 41, a centrifugal force fo and a static pressure difference DELTAp in a circumferentia direction are applied to the compressed air flow. A resultant force consisting of this centrifugal force fo and the static pressure difference DELTAp is provided with a component in a direction opposite to that of a divided force fc of a Coriori's force and thus thease offset each other. Therefore, by balancing the vector sum of the centrifugal force fo and the static pressure difference DELTAp with the devided pressure fc of the Corioli's force, an imbalanced component of these can be reduced in the vicinity of a hub 2 and a casing. Also generation of a secondary flow among rows of the rotor blades 40 can be limited.
