Title: Optical disk
Inventor: KYODA TAKESHI
IPC: G11B7/24
Filed: 1992-01-31
Abstract: PURPOSE:To prevent the generation of the warpage of an optical disk by substantially equaling the products of the internal stresses of 1st and 2nd resin protective layers respectively formed on both surfaces of a plastic substrate and the thickness of the layer. CONSTITUTION:At least an optical recording layer is formed on one surface of the plastic substrate and the resin protective layer is formed thereon. The 2nd resin protective layer is formed on the other surface. The internal stresses (force per unit sectional area) generated in the 1st and 2nd resin protective layers are respectively designated as sigma1 and sigma2 and are so set that the conditions of sigma1Xsigma1=sigma2Xsigma2 substantially hold. The internal stresses generated in the respective resin protective layers on both surfaces of the plastic substrate are substantially equaled in this way and, therefore, the generation of the warpage of the optical disk is prevented.

Title: Magnetic disk device
Inventor: ASADA HIDEO
IPC: G11B21/10
Filed: 1990-01-25
Abstract: PURPOSE:To simplify a head positioning operation by discriminating an offset amt. of a head positioned with a servo surface position error signal from a data surface position error signal that is produced from a data surface servo data to be read by the head selected by a host device. CONSTITUTION:The error signal 65 is generated by a data surface position error signal generating circuit 4 from the data surface servo data 5 to be read by the data head selected by the host device, while the error signal 66 is generated by a servo surface position error signal generating circuit 2 from a servo surface servo data 1. A difference between the signals 65 and 66 is compared with a reference voltage level 8 by a level detecting circuit 7, and when the difference exceeds this level, a data surface servo operation signal 9 is generated. During the movement of the head, the signal 66 is switched to a position error signal 12 by a switching circuit 10 upon the receipt of a seeking operation signal 15 of a control circuit 11, and during holding of the head, the signal 66 is taken, and when an instruction signal 9 is inputted, the signal 65 is taken. The reference speed for positioning the head is decided by the control circuit 11 when a seeking command 68 is received, and a voice-coil motor 56 is driven. The seeking is stopped when the signal 12 is at 0-level.

Title: Method and device for controlling falling velocity of test piece
Inventor: KIKUCHI TAKAMASA
IPC: G05D13/34
Filed: 1989-01-26
Abstract: PURPOSE:To attain weightless tests using various test pieces by actuating an air pressure control part based on the signals given from a fall conforming means and a pressure detecting means and controlling the velocity of a test piece falling within a perpendicular and decelerating tubes. CONSTITUTION:The pressure in a perpendicular tube 1 is measured by a pressure detecting means 15 provided in the tube 1. Thus the total weight of a test piece (s) can be recognized and the proportional relation is unequivocally decided between the falling velocity and the relief area of the piece (s). The relief area can be increased/decreased by opening/closing an air pressure control part 9 of the tube 1. Then the falling velocity of the piece (s) can be controlled. The decelerating tube 7 attached at a lower end part of the tube 1 has a diameter smaller than that of the tube 1. Therefore the falling velocity of the piece (s) is automatically reduced when the piece (s) rushes into the tube 7. In addition, the air pressure control parts 12a and 12b of the tube 7 are properly opened/ closed so that a sudden change can be released for the relief area formed between both tubes 1 and 7. Thus it is possible to prevent a sudden pressure change that affects the piece (s).

CONSTITUTION:Plural normal patterns NOR1-NOR4, introduction patterns INT 1-INT3, fill-in patterns FIL1 and FIL2, and ending patterns END1-END3 are prepared by respective accompaniment styles of a march, waltz, and rock as the automatic accompaniment patterns. Automatic switching to a pattern corresponding to a last performance pattern is performed when music changes from an introduction pattern to a normal pattern, when a fill-in pattern is inserted into the normal pattern, and when the music changes from the normal pattern to an ending pattern. Further, a transition pattern which is automatically determined is changed as the player specifies.

Title: Ac arc stabilizer
Inventor: HAGIWARA SEIGO
IPC: B23K9/073
Filed: 1978-02-16
Abstract: PURPOSE:To maintain the stable spark discharge and to reduce the noise, by causing the spark discharge through the spark gap of comparatively long interval at starting the arc, and by reducing the input voltage for the high-frequency generator and shortening the spark gap after the welding curent is detected. CONSTITUTION:At starting the arc, a high input voltage is impressed on the high- frequency transformer 25 through the normally closed contact 22 of the transformer 21, and a high-frequency voltage is impressed by the spark gaps 24, 25, on the torch 1 through the coupling coil 8. When the detective relay detects the welding curent, the contact 22 opens, the contact 23 closes, the voltage impressed on the high-frequency transformer 5 goes down, the voltage impressed on the transformer 5 goes down, and the high-frequency voltage of the transformer 5 is greatly reduced. According to this method, the AC arc stabilizer with high-frequency noise of low level can be obtained.

Title: Radio wave sensor for satellite broadcast reception
Inventor: FURUTA TAKASHI
IPC: H01Q3/02
Filed: 1989-01-26
Abstract: PURPOSE:To detect and judge quickly whether or not the reception of a ratio wave of a satellite broadcast is enabled at the location by rotating a small sized planer antenna at a high speed in the absence of a reception signal at the reception antenna. CONSTITUTION:A broadcast reception ratio wave sensor judges a small sized planer antenna 1 at a high speed in the absence of a reception signal at a reception antenna to judge whether or not the reception of the ratio wave of the satellite broadcast is attained. If the reception is enabled, the arrival direction of the ratio wave is judged and the satellite broadcast reception antenna A is rotated so that the reception direction of the satellite broadcast reception antenna A is directed to the arrival direction. That is, even when the tracing of the satellite broadcast reception antenna A is disabled because of the presence of a rapid direction change of a mobile body or vibration, the small sized planer antenna 1 driven at a high speed detects and judges the arrival direction of the radio wave of the satellite broadcast quickly so as to direct the reception direction of the reception antenna A to the direction of the broadcast satellite without any time loss.

Patent JP-S63184919-A (JP)
Title: Magnetic recording medium
Inventor: SAKAMOTO KAZUNORI
IPC: C09D7/12
Filed: 1987-01-28
Abstract: PURPOSE:To permit hard kneading effective to exert sufficient shearing force on the kneaded matter of magnetic powder by incorporating a specific amt. of partially esterified metal-contg. higher fatty acid or metal-contg. higher fatty acid incorporated therein with a hydrophilic functional group by partial hydrolysis as a surfactant into the magnetic powder. CONSTITUTION:The partially esterified metal-contg. higher fatty acid or the metal-contg. higher fatty acid incorporated therein with the hydrophilic functional group by partial hydrolysis is incorporated at 0.5-1.0wt.% as the surfactant into the magnetic powder. While the surfactant decreases the friction between the kneaded matter and the wall surface of a kneading machine by the characteristics as a solid lubricating agent intrinsically possessed by the metal- contg. higher fatty acid, said surfactant plays the role of a surface treating agent for the powder by inducing the chemically active group such as ester group or hydrophilic functional group into the molecule, thus eventually suppressing the generation of heat arising when a liquid component is immersed therein. The sufficient shearing is thereby applied to the kneaded matter while the generation of heat during kneading is suppressed. The good heard kneading is thus permitted.
