Title: Dynamic loudspeaker
Inventor: SAEKI SHIYUUJI
IPC: H04R9/02
Filed: 1982-06-17
Abstract: PURPOSE:To obtain the flat frequency characteristics, by attaching a voice coil to a rectangular diaphragm with eccentricity and at the same time bonding the edge of the diaphragm further away from the voice coil to a frame. CONSTITUTION:A rectangular diaphragm 1 is driven with eccentricity by a voice coil, and a part of an edge member at the side further away from the voice coil is adhered to a frame. The length of the edge adhered part is selected to change the stiffness value of the edge part. The stiffness value at the side further away from the voice coil is set larger than that of the other side. Thus the diaphragm 1 has different amplitude values at its each point and produces all vibrations in-phase. Therefore no negation of vibrations due to adverse phase components is produced. This ensures the flat frequency characteristics.

Title: Phase comparator
Inventor: WADA KENZO
IPC: H03D13/00
Filed: 1988-04-30
Abstract: PURPOSE:To obtain the said satisfactory phase comparison output with no use of a transformer by using a rat-race type power distributor to perform the double distribution with a phase difference pi. CONSTITUTION:When a reference signal is supplied from a reference signal input port 1, a step recovery diode 12 is driven for production of a pulse component. These produced pulse outputs are applied to the Schottoky diodes 13 and 14. At the same time, a microwave is supplied from an RF input port 2 and undergoes the double distribution with a phase difference pi through the rat-race type power distributors 4-7. These distributed microwaves are applied to the ports 1 and 2. Then the signals applied to both ports 4 and 6 are mixed with the signals applied to both diodes 13 and 14. Thus a phase comparison output signal is transmitted from a phase comparison output port 3. In such a way, a satisfactory phase comparison output signal is obtained with no use of a transformer.

Title: Low-loss oxide magnetic material and winding part
Inventor: CHIBA TATSUYA
IPC: H01F1/34
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To achieve the compact configuration of a magnetic core by specifying the average crystal-particle diameter of an Mn-Zn ferrite sintered body, whose main component composition is specified and obtaining the high specific resistance oxide magnetic material at the low resistance loss. SOLUTION: A Mn-Zn ferrite comprising the main component constitution of 48.0-50.0 mol.% of Fe2 O3 , 29.0-46.0 mol.% of MnO and the remaining part of ZnO is measured. After the mixing of two hours using attriter, particles are formed by a spray drier. The formed particle powder is preheated by a rotary kiln. Then, the obtained powder is crushed by using attriter. Thereafter, the particles are formed to the average particle diameter of 10 μm or more with a spray drier and pressed into the toroidal form. Sintering is performed at 1,250 deg.C. Furthermore, the sintered body has a resistivity of 2×10<9> Ωcm or more. Due to high resistivity, the sintering of a winding and the magnetic body as a unitary body by conductive paste can be performed, and the miniaturization can be obtained. As a result, the loss can be decreased mainly by the reduction of hysterisis loss.

Title: Heating method with current feed to electric resistor
Inventor: YAMADA YOSUKE
IPC: H05B3/00
Filed: 1990-04-20
Abstract: PURPOSE:To prevent a resistor element from destruction by forming a plurality of current feed paths, through which current is fed upon selecting two of current feeding electrodes arbitrarily, and performing the current feeding while the current feed paths are changed over one after so that the resistor element is heated uniformly. CONSTITUTION:Current is first fed to a current feed path leading from an electrode 3a to another 3c, and at the same time, current is fed to a current feed path leading from an electrode 3b to a one 3d. Then the circuit for supplying the electrodes with electricity is changed over to feed current to the path leading from the electrode 3b to 3a, and at the same time, current is fed to the path leading from the electrode 3d to 3c. These procedures are performed alternately, and thereby the whole core 1 is heated uniformly. Because current feeding to the path from the electrode 3a to 3c encounters a larger resistance of core 1 than feeding current to the path from the electrode 3b to 3a, the current feeding time must be prolonged accordingly so as to make uniform the temp. of the core 1. This can prevent physical damage such as crack or craze resulting from temp. difference.

IPC: B28B11/08
Filed: 1990-04-20
Abstract: PURPOSE:To enable an earthenware raw material to be reformed into a complicate shape by placing an earthenware raw material formed by lathe means or casing means and the like on a forming mold, and constituting a closed vessel with a flexible material that is adaptable to the outer shape of the earthnware raw material, and then injecting pressurized fluid into the closed vessel for press-deforming it. CONSTITUTION:An earthenware raw material 6 molded into a multi-production shape by lathe means or casting means is placed on a forming mold 5 and a closed vessel 3 is secured thereto such that the inner wall surface 1 of the closed vessel 3 formed with a flexible material comes into close contact with the earthenware raw material 6 and, for example, fluid (air) pressurized by press means 7 comprising an air compressor is force-fed into the closed vessel 3 via a pressure pipe 8. Since the closed vessel 3 is formed by a rigid material in its outer wall 2, the flexible material deforms and comes into contact with the earthnware raw material 6 tightly by pressurized air and, further, by supplying pressurized air thereinto, the earthenware raw material 6 is pressed while maintaining the outer peripheral shape thereof adhered closely to the flexible material and thus deforms to be adaptable to the forming mold 5 or, when the deformed part thereof is not opposed to the forming mold 5, deformation according to the pressurized pressure occurs therein, thereby forming a complicate shape that is utterly different from the shape molded by multi-production means.

Filed: 1984-05-25
Abstract: PURPOSE:To insulate and separate active semiconductor regions formed on an insulating substrate by emitting a light from the back surface of the substrate in reactive accumulation gas. CONSTITUTION:A single crystal Si 32 is epitaxially formed on a sapphire substrate 31, a resist mask 33 is formed, an RIE is performed, and an ultrafine groove 34 is formed. The mask is removed, secured to a sample base 13, and heated at 300 deg.C. Mixture gas of SiH4 and O2 is fed into a vaccum vessel 11 in this state, and a laser beam 17 is emitted from a light source 16 to the back surface of a sample. At this time, a beam 17 is reflected on the layer 32, and the beam 35 passed through the groove 34 decomposes the SiH4 to SiHx radical, reacted with O2 to accumulate only SiO2 36 in the groove 34. Since the SiO2 36 entirely transparent for ArF laser beam 35, the SiO2 36 is accumulated thickly as time goes, and eventually completely buries the groove 34. With this configuration, the active region can be insulated and separated in the simple steps, and charged beam does not damage the active region.
