Title: Bass-reflex type speaker device
Inventor: YOSHIDA KOJI
IPC: H04R1/26
Filed: 1995-05-17
Abstract: PURPOSE: To make a device compact by composing it from a front buffle for supporting a speaker for low-frequency sound and the speaker for high-frequency sound attached so as not to close a bass-reflex duct. CONSTITUTION: The bass-reflex duct 6 is the bass-reflex duct 6 in a tapered cylindrical shape arranged next to the speaker 3 for the low-frequency sound of the front buffle 1 and a diameter is made gradually smaller towards the side of a rear box 2. The speaker 4 for the high-frequency sound is attached to the tip on the side of the rear box 2 of the bass-reflex duct 6. A clearance is secured on the peripheral edge of the speaker 4 for the high-frequency sound and the low-frequency sound emitted from the speaker 3 for the low-frequency sound to the inside of this bass-reflex type speaker device is emitted from the clearance through the bass-reflex duct 6 to the outside.  Thus, since the function of other than the bass-reflex duct 6 is also provided in the bass-reflex duct 6, space required for the arrangement of the bass-reflex duct 6 is reduced and the enlargement of the speaker device is prevented.

Title: Powder for base layer of coating type magnetic recording medium and magnetic recording medium using the same
Inventor: SAITO KAZUHISA
IPC: G11B5/706
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To form a nonmagnetic layer having superior surface smoothness by depositing a specified amount of a carboxylic acid on the surface of α- FeOOH particles. SOLUTION: A carboxylic acid as an organic compound is incorporated into the surface of α-FeOOH (iron oxyhydroxide) particles to modify the surface property of the particles, and the particles are used as powder for the base layer of a coating type magnetic recording medium. It is sufficient that the amount of carboxylic acid deposited is only that which is required amount to cover the α-FeOOH particles and is added with respect to the range of 0.1 to 10 wt.% of the α-FeOOH powder to the powder. If the amount is less than 0.1 wt.%, the desired effects are not obtained due to the low viscosity of the coating material, and even if it is added in excess of 10 wt.%, its effects will be saturated and will affect the coating material composition.  Thereby, the dispersibility of α-FeOOH particles to the binder resin can be improved, and the viscosity of the coating material can be decreased. Thus, the obtained base layer has superior surface smoothness.

Title: Manufacture of magnetic recording medium
Inventor: ICHIJO MINORU
IPC: G11B5/84
Filed: 1989-06-05
Abstract: PURPOSE:To obtain an application type magnetic recording medium whose running property and durability are excellent by subjecting the surface of a magnetic recording layer to plasma processing. CONSTITUTION:First of all, the plasma processing is executed by exposing the surface of an application magnetic recording layer 10 to plasma in a vacuum tank. As a result, gas in the vacuum tanks is activated in the plasma, and a low molecular weight component on the surface of the recording layer 10 is brought to etching. Simultaneously, a motion of the surface of the recording layer 10 becomes active, each radical generated by etching is coupled and the crosslinking density of the surface of the recording layer 10 rises. As a result, in the vicinity of the surface of the recording layer 10, a part 11 of the degree of precise and high crosslinking is formed. By forming this precise and high crosslinking degree part 11, the durability of the magnetic recording medium is improved. In this regard, non-organic compound gas such as rare gas, oxygen, nitrogen, fluorine, carbon tetrafluoride, carbon monoxide or water vapor, etc., is led into the vacuum tank singly or as a mixture, and under its existence, the plasma processing is executed.

Filed: 1979-11-05
Abstract: PURPOSE: To provide a simple structure offering reduced installation and running costs by installing the first catalytic layer having reaction and nonreaction sections and the second catalystic layer consisting of a reducing catalyst.  
     CONSTITUTION: A single ammonia or an ammonia-containing organic mixture gas is admitted through the gas inlet 1 and is preheated to the specified temperature in the heating section 2. The preheated gas is passed through the first catalytic layer 8 consisting of an oxidation catalyst 3 and a noncatalyst 4. The gas passed through the oxidation catalyst 3 causes its ammonia content to be reacted with oxygen in the gas and transformed into nitrogen oxides and steam, and an organic gas, if contained, is also oxidized into CO 2  and steam. On the other hand, the gas passed through the noncatalyst 4 passes as it is. Next, the nitrogen oxides and ammonia in the passed gas are decomposed into nitrogen and steam by the action of the reducing catalyst in the second stage catalytic layer 5. The oxidation catalyst 3 and noncatalyst 4 are to be proportioned to obtain the optimal ratio suited to the purpose.

Abstract: PURPOSE:To accurately set the phase difference between two output signals to 180 deg. by obtaining an output signal from the collector of a third transistor(TR) which has the base connected to a reference power source and has the emitter connected to the collector of a first TR. CONSTITUTION:First and second TRs Q1 and Q2 whose emitters are connected in common through a first resistance R1, a signal source Vi from which a signal is applied to the base of the first TR Q1, a third TR Q3 which has the base connected to the reference power source and has the emitter connected to the collector of the first TR Q1 through a second resistance R2, constant current sources I1 and I2, and reference power sources E1 and E2 are provided. In this case, the resistance value of the second resistance R2 is made equal to that of the first resistance R1, and the variance in phase due to the first resistance R1 is compensated by the second resistance R2. Consequently, a current i3 flowing to the third TR Q3 is equal to a current -i2, and the phase difference between both signals is pi. Thus, signals of opposite phases are correctly obtained in output terminals OUT1 and OUT2.
