Title: Loudspeaker
Inventor: HARA KOZO
IPC: H04R7/12
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a loudspeaker capable of outputting the frequency bands of a tweeter and a ribbon-shaped speaker. SOLUTION: A ring-shaped diaphragm 2 having a C-shaped cross section is arranged on a cylindrical bobbin 3, and the top end of this ring-shaped diaphragm 2 is made into a free end. The speaker using the ring-shaped diaphragm 2 enables reproduction with piston vibrations in a high frequency range and with divided vibrations in an ultrahigh frequency range. Thus, by using such a speaker in place of a tweeter arranged in a three-way speaker system, it is not necessary to use a ribbon-shaped speaker, a matching transformer is not required and it is not necessary to care of speaker arrangement.

Title: Photodetector
Inventor: KASUYA YUKIO
IPC: H01L31/10
Filed: 1986-05-13
Abstract: PURPOSE:To increase the S/N ratio as a signal representing the brightness ratio of detected area by a method wherein photoelectric converting parts and an auxiliary electrode are connected by an extension part of either one of the first or the second conductivity type layer. CONSTITUTION:When a photodetector is irradiated with light from a detected area such as a picture image from an insulating transparent substrate 11 side, such light, after penetrating the insulating transparent substrate 11, reaches photoelectric converting parts 15 and the first conductivity type layer 17 including the extension part of said photoelectric converting parts 15. Furthermore, carriers such as electrons.hole pairs corresponding to the intensity of said light are generated in the photoelectric converting parts 15. When the space between an auxiliary electrode 23 and the second electrode 25 in such a state is impressed with specified voltage to be an inverse bias, said carriers can be taken out as photoelectric current. Through these procedures, the brightness ratio of a detected area can be detected.

IPC: B60G17/015
Filed: 1990-04-24
Abstract: PURPOSE:To prevent generation of sounds and vibrations and enhance the comfort in a car cabin by providing a car suspension device which is equipped with a shock absorbing device, whose damping force characteristics is variable with the product of the superspring/subspring relative displacement and the superspring/subspring relative velocity. CONSTITUTION:A control unit 8 is fed with superspring/subspring relative displacement signals r1-r4 from car height sensors 41-44 mounted in shock absorbers 1-4, followed by differentiating process to determine the superspring/ subspring relative velocity. Then the superspring/subspring relative displacement for each wheel is multiplied with the relative velocity ri to determine the judgement function. Then the square of the superspring/subspring relative velocity for each wheel is multiplied with the gain value (g) so as to set the specific value Ki. If the judgement function hi is smaller than the specific value Ki, it shall be conditioned as vi=1, and if the hi is larger than Ki it shall be assumed that vi=0. Then actuator control signals upsilon1-upsilon4 are emitted. Thus generation of sound and vibration due to unnecessary change of the damping force characteristics can be prevented.

Title: Melt processing method for waste active sludge
Inventor: HIROKAWA NORIO
IPC: C02F11/10
Filed: 1979-08-30
Abstract: PURPOSE: To stabilize arc and enable easy melting by a method wherein the volatile content of the waste active sludge is reduced to be 50% or less by burning and later the burnt residue is charged in an arc fuanace.  
     CONSTITUTION: The waste active sludge 3 is thrown into a totary furnace 1 from a hopper 2. As the burning condition in the rotary furnace 1, the volatile content of organic substances and the like except for humidity is reduced to be 50% or less. Residue 8 left after burning is sent from the rotaty furnace 1 through a feeder 6 to a hopper 7, where it is stocked, and then is charged in the closed-type arc furnace 9. The arc furnace 9 is started by laying grained coke, iron scraps, etc. between ele- ctrodes at the bottom of the furnace and heating them in redheat through electrification, and the burnt residue 8 is dropped thereon to be heated and melted. The heavy metal compound contained the melted residue is reduced in the arc furnace and sinks down to the bottom of the furnace, getting metal phase 15. Organic substances accounting for the most part of the residue get slag phase 14, since they are hard to reduce, and are gathered on the metal phase 15.

Filed: 1987-05-06
Abstract: PURPOSE:To improve S/N by respectively allotting specified codes to the leading edge and the trailing edge of synchronizing signals in television signals and transmitting them with A/D conversion data in other television signals. CONSTITUTION:If a trailing edge detector 4 and a leading edge detector 5 output the specified codes, a switch 7 substitutes the output of a code detection converter 6 with the specified codes. The outputs of the switch 7 are converted in series into objective serial digital signals in a parallel/serial converter 3 and are transmitted to a signal output terminal T4. Here, different specified digital codes are allotted to the trailing edge and the leading edge of the synchronizing signals in the television signals and the specified digital codes are transmitted to the television signals excepting the trailing edge and the leading edge of the synchronizing signals without including the codes as the digital codes after A/D conversion. Since the synchronizing signals can be transmitted by two specified codes and the codes excepting two specified codes are effectively used for the A/D conversion of video signals, the video signals which satisfactory S/N can be transmitted.

Title: Soldering method for printed wiring board
Inventor: TSURUSAKI ARATA
IPC: H05K7/14
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To improve the strengths of soldered junctions between the earth lands of the printed wiring board of a television tuner, etc., and a shielding case. SOLUTION: Hardened plated copper-like layers 25h are formed successively from earth lands 22e arranged along the end edge of a printed wiring board 20 by applying copper paste 25 to the end face of the wiring board 20 and heat-treating the paste 25. Since the earth lands 22e are connected to the layers 25h with pawl sections 12 formed by notching the side wall of the case 1C and solder junctions Sd by facing the pawl sections 12 and the end edges of the earth lands 22e of the wiring board oppositely to each other, the areas of the solder junctions corresponding to the layers 25h increase and the strengths of the solder junctions are improved.  When the pawl sections 12 of the case 10C are made narrower in width than the hardened plated copper-like layers 25h, the strengths of the solder junctions are further increased, because the solder infiltrates to the end faces of the pawl sections 12.
