Title: Monolithic cd storing case
Inventor: SAKOU MORIZOU
IPC: B65D85/57
Filed: 1995-05-26
Abstract: PURPOSE: To obtain a paper-made CD(compact disc) storing case that is lightweight and excellent in impact resistance and heat resistance, by a method wherein a square base paper made of two-side corrugated board with a thickness within a specified range is formed into the CD storing case by press-hot deep drawing. CONSTITUTION: A sheet of thin two-side corrugated board with a thickness of 1.0-1.6mm is integrally formed into a CD storing case 1 by press-hot deep drawing. To store a CD in a stowing part 2, the center hole of the CD is fitted on a protruding fitting part 7 formed at the central part of a recessed part 5 of the storing part 2 and the peripheral place of the central hole is supported on the upside of a protruding mount 6. The inside face of a lid 3 comes in contact with a flange part 8, the downside (or upside) of the CD stowed and the upside of the protruding fitting part 7 to fix the CD stored. Since the recorded side (or downside) of the CD stored is separated from the bottom of the recessed part 5 of the storing part 2 and only the peripheral part of the center hole, i.e., the non-recorded part on the recorded side, is supported, the recorded side is prevented from being contaminated and damaged.

Title: Negative feedback amplifier
Inventor: GOTOU HIROSHI
IPC: H03F1/34
Filed: 1983-08-20
Abstract: PURPOSE:To couple directly a line amplifier and a recording amplifier by decreasing a time constant comprising a negative feedback resistor of a negative feedback amplifier and a capacitor between a negative feedback point and a common point less than a time constant viewed from a control circuit to control a transistor (TR) of said capacitor circuit. CONSTITUTION:The negative feedback resistor R3 is connected between an output point of the negative feedback amplifier 2 and its negative feedback point, and a passive circuit having a series capacitor C5 is connected between the negative feedback point and the common point through a switching TR1. The 1st time constant comprising the negative feedback resistor R3 and the capacitor C5 is decreased less than the 2nd time constant comprising an impedance viewed from the control circuit connected to a base of the TR1 and the capacitor C5. Thus, the effect due to a charge current is almost eliminated and distortion is reduced remarkably.

Title: Optical disk driving device
Inventor: KURIBAYASHI AKIRA
IPC: G11B23/50
Filed: 1985-07-12
Abstract: PURPOSE:To reduce an error rate for the reproduction of information by providing a driving means which shifts a cleaning means to a position where a contact is secured with the disk surface in response to the action signal given from a host device owing to a reproduction error. CONSTITUTION:An optical disk controller 20 contains a reproduction error detector which decides whether the received information is correct or not. The controller 20 gives an instruction to an optical disk driving device 21 to clean the surface of an optical disk 1 via a brush 6 and to retry reproduction in case the reproduction is wrong due to the wrong information. When receiving said instruction, the driving device 21 lifts the brush 6 up to a position where the contact is secured with the surface of the disk 1 by means of a solenoid 5 in order to remove the dust, etc. Then the brush 6 is detached again from the surface of the disk 1. The brush 6 is kept contact with the surface of the disk 1 only when a reproduction error is produced. Other wise the brush 6 is kept away from the surface of the disk 1. This prevents the undesired damage given to the disk 1 and reduces the error ratio for the reproduction of information.

Title: Method for preventing corrosion of copper-base piping
Inventor: SHINOHARA YOSHIHARU
IPC: C23F11/167
Filed: 1984-07-23
Abstract: PURPOSE:To restore the internal corroded part of copper-base piping and to protect the piping from corrosion by passing water or hot water contg. phytic acid or a salt thereof at a proper high concn. through the piping having the corroded part for a prescribed period and by reducing the concn. CONSTITUTION:When the inside of copper-base piping for supplying water or hot water is corroded, phytic acid or a salt thereof is added to water or hot water flowing through the piping by 1.1-10ppm to restore rapidly the corroded part, and after the lapse of about 1 month, the amount of phytic acid added is reduced to 0.01-1.0ppm so that the piping is protected from corrosion. Since phytic acid or a salt thereof maintains its corrosion preventing effect for about 1 month, it is intermittently added at intervals of about 1 month after reducing the concn. to 0.01-1.0ppm.

Title: Speaker device and television receiver using this
Inventor: YOSHIDA TOMOISA
IPC: H04R5/02
Filed: 1995-05-26
Abstract: PURPOSE: To obtain excellent acoustic characteristics in the wide ranges from a low pass to a high-pass by setting the mounting location of a speaker to the intermediate part of the closed end and opened end of a sound tube and effectively absorbing a standing wave. CONSTITUTION: By mounting a speaker 3 at the location which is closer to a closed end side by the 1/3 length of the total length of a sound tube 4 and making the speaker opposite to the location of the belly of a 3/4 wavelength standing wave, the resonance of the standing wave is suppressed. In the waveguide 43 of the sound tube 4, the cross section is extended toward an opening end. In the waveguide 44, the cross section is reduced toward the closed end. By the asymmetry of the cross section, the reflection wave at the closed end is weakened. The sound absorbing material 5 on the closed end side absorbs the total refelction wave from the opening end and the circular truncated cone shaped projection part 6 opposed to the sound wave radiation part of the speaker 3 mitigates the change of the acoustic impedance in the connection part of the speaker 3 and the sound tube 4.  Thus, excellent acoustic characteristics can be obtained.
