Title: Phase inversion type speaker
Inventor: ONO HIDENORI
IPC: H04R1/26
Filed: 1990-03-16
Abstract: PURPOSE:To obtain a low sound with a sufficiently hard sense of a sound tone by adopting the constitution of the speaker system such that a sound wave radiating from a rear side of a woofer unit is subjected to attenuation of a high frequency tone in a low frequency region in a 2nd chamber and the result enters a 1st chamber with a port. CONSTITUTION:An internal space of a speaker box 10 is separated into a 1st chamber 16 having a tweeter unit 12 and a 2nd chamber 17 with a woofer unit 13 by a partition plate 15 having an opening 15a at its part, a sound absorbing member 18 is adhered to the inner face of the 2nd room 17 and a port 14 linking the inside and the outside of the speaker box is provided to the 1st chamber 16. That is, the sound wave radiating from the rear side of the woofer unit in the 2nd chamber 17 is subjected to attenuation of high frequency sound by the sound absorbing member in the inner face of the 2nd room 17 and enters the 1st chamber 16 through the opening of the partition plate and goes to external from the port 14 provided to the 1st chamber 16. Since the sound wave is subjected to attenuation of high sound frequency in the 2nd chamber 17 and enters the 1st chamber 16 with the port 14 in this way, the high frequency sound in the sound wave outputted from the port 14 is less and the low frequency sound is emphasized. Then a frequency characteristic is obtained in which the gain of a low frequency sound is increased and the gain of a high frequency sound is decreased and a low frequency sound with a sense of a hard tone is realized.

Title: Optical detector
Inventor: KAMEI MITSUHITO
IPC: H01J43/30
Filed: 1981-04-29
Abstract: PURPOSE:To enable highly reliable measurement free from the effect of disturbance by a simple constitution, by setting a bleeder current of a photomultiplier tube to set a prescribed relation-ship with a signal current and thereby giving a AGC function to the multiplier tube itself. CONSTITUTION:A negative high voltage is impressed on the bleeder of a photomultiplier tube and thereby a bleeder current iB is made to flow from the earth side through the final resistor RB of the bleeder. Similarly, a signal current iP flows from the earth side via a load resistor RL, a plate 21, etc., and thus a bleeder voltage VB relating to the gain of the photomultiplier tube is made to have a value: VB=(iB-iP)XRB. Accordingly, the voltage Vb decreases when the current ip increases and vice versa, and thus an AGC function is given to the multiplier tube itself. When this bleeder current is set in the range of 50-200% of the signal current, the latter is made stable in relation to the change in a reflection factor and the fluctuation of the quantity of light of a light source  which turn to be disturbance, and thereby an optical defect detector enabling  highly reliable measurement free from the effect of disturbance can be formed  by a simple constitution.

IPC: B01J20/02
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To obtain a deoxygenating agent by reuse of waste material of used magnetic recording media by forming swell on a coated magnetic recording medium in a facial direction and making the recording medium retain polyelectrolyte. SOLUTION: A magnetic layer primarily consisting of ferromagnetic metal particles such as iron, nickel and the like and a bonding agent is formed on a substrate such as polyethylene terephthalate or the like to make a coated magnetic recording medium. Swell is formed in a facial direction of a used magnetic recording medium so that a space is formed between two fiagments of the magnetic recording medium when the two fiagments are disposed to overlap one another. Diffusion of air, therefore, is enhanced so that capacity of deoxygenation of the ferromagnetic metal particles can be sufficiently exerted. When the magnetic layer is made to retain a polyelectrolyte such as acrylic acid, metacrylic acid and the like therein, ions of the polyelectrolyte functions to enhance oxidation of the ferromagnetic metal particles so that activity of deoxygenation is enhanced.
