Title: Chip type noise elimination filter
IPC: H03H7/075
Filed: 1992-03-09
Abstract: PURPOSE:To suppress distortion of a signal waveform inexpensively by providing an earth electrode used to form a capacitor with a resistor connecting outer electrodes of both ends of a dielectric bobbin to both sides and connecting both ends of a winding wound in the middle of the dielectric bobbin to both outer electrodes. CONSTITUTION:Outer electrodes 14a, 14b and a resistor 16 connecting them are formed to both sides of one end of a dielectric bobbin 12. A thermet and carbon resistor subject to thick film print or formed to be thin film by vapor deposition or the like is used for the resistor 16. Moreover, a resistance of the resistor 16 is selected to be nearly 10-300ohms based on balance between suppression of distortion in a signal waveform or noise elimination. Furthermore, earth electrodes 18a, 18b forming a capacitor with the resistor 16 and a winding 20 forming an inductance in the middle of the bobbin 12 are provided on the same face as the resistor 16 and both ends of the winding 20 are connected to the electrodes 14a, 14b. Thus, a pi type filter and a damping resistor are formed and the signal waveform distortion is inexpensively suppressed.

Abstract: PURPOSE:To reduce the number of demodulating/modulating circuits to one to simplify the constitution by constituting a device having the dubbing function so that the modulated signal detected by a read head is recorded on a magnetic disc through a write head as it is. CONSTITUTION:When picture information recorded on one magnetic disc is dubbed on the other magnetic disc, the modulated picture signal detected by a read head 5 passes a head amplifier 6 and is subjected to required signal correction in a correcting circuit 32 without being demodulated and is inputted to a recording amplifier 12 and is recorded on the magnetic disc by write heads 13 and 34. When the reproduced signal is outputted to the external, a switch SW attached to a demodulating/modulating circuit 31 is turned on to operate this circuit 31 as a demodulating circuit, and the output of the head amplifier 6 is outputted as a video signal to the external through a route indicated by solid lines. When the input signal from an input terminal 33 is recorded, the switch SW is turned off to operate the demodulating/modulating circuit 31 as a modulating circuit, and the input picture signal is recorded on the magnetic disc through a route indicated by broken lines by heads 13 and 34.

Title: Surface treatment apparatus capable of feeding and discharging liquid in short time
Inventor: TAKEMURA ISAMU
IPC: C25D11/00
Filed: 1979-04-23
Abstract: PURPOSE: To place and lift off the object to be treated into and from the treating liquid tank without moving vertically, by providing a notch in the treating liquid tank so that the object to be treated may pass through and installing a shutter in the notch which moves up and down with the treating liquid level, when performing surface treatment such as plating.  
     CONSTITUTION: When performing surface treatment such as plating, a treating liquid tank 1 is communicated with an auxiliary tank 5 for liquid level adjustement disposed in an upper position and a storage tank 12 for the leaked liquid. A notch 1a is provided in the side wall of the treating liquid tank 1 in the direction of passing of the object to be treated, and a shutter 3 which moves up and down by the buoyancy of the liquid in a inside guide 4 is provided. The pressure inside the auxiliary tank 5 is reduced by a vacuum tank 10 to suck up the liquid in the treating liquid tank 1. As a result, the liquid level in the tank 1 is lowered and the shutter 3 is set down to open the notch 1a, so that the object to be treated enters the tank 1 in horizontal movement. Next, an electromagnetic valve 8 is closed, and a valve 6 of an exhaust pipe 7 is opened to set the tank 5 to atmospheric pressure, thereby feeding the liquid into the tank 1. At the same time, the shutter 3 goes up to close the notch 1a to treat the object with the liquid. By repeating this operation, the tank 1 is emptied, and the notch 1a is opened, then the object is transferred to a next process.

Abstract: PURPOSE: To reduce the area of a substrate by arranging the outer lead of a leadframe in the center on the lower surface of a package, thereby eliminating the space for coupling the outer lead of the package with the metal wiring on a printed wiring board at the time of mounting. CONSTITUTION: A plurality of outer leads 23 to be connected with a printed wiring board are bent toward the lower part of a chip paddle 21 at the inner end of a plurality of inner leads 22 coupled with a semiconductor chip 1 and arranged in the center on the lower surface of a package.

Filed: 1982-03-31
Abstract: PURPOSE:To make superior electric insulation and thermal conductivity and to accomplish high density by a method wherein a plastic adhesive layer is formed on a surface corresponding to the supporting plate of a thermosetting plastic film and a metallic foil corresponding to a circuit element is formed on the other. CONSTITUTION:A polyimide film as a insulating film 7 is glued onto the plane 11 of a radiating fin 1 with a plastic adhesive agent and a metallic plate 3 is glued to a metallic foil 71 selectively formed on the film 7, whereas a transistor pellet 41 is glued to the metallic plate 3 in a conductive state. Moreover, a wiring pattern 72 is formed on the periphery of the metallic plate 3. With this construction, insulation across the fin 1 and the metallic plate 3 for mounting a heat generating element is secured uniformly and satisfactorily because of the thermohardened film 7. In addition, because the polyimide film and an organic plastic layer 75 of fluoric series in the adhesive layer are extremely thin, reduction in heat radiation can be minimized. Furthermore, heat radiation on the side where the metallic plate 3 is mounted is never affected. For this reason, the metallic plate 3 can be made compact.

Title: Rolling bearing
Inventor: MUTO YASUYUKI
IPC: F16C33/58
Filed: 1995-03-10
Abstract: PURPOSE: To maintain good vibrating characteristics without any need additional improvement to roundness by making the number of waviness existing in a track a specific one based on the number of rolling elements. CONSTITUTION: On the tracks of inner and outer rings of rolling bearings 4, 2, unavoidable waviness exists in processing. Assuming that the number of rolling elements 5 is Z and (n) is a positive integer, when as much waviness as the number of crests nZ exists, both the inner and outer rings do not displace in the radial direction because the rolling element 5 is positioned at the top or bottom of the waviness at the same time, however, vibration occurs in the axial direction by pressing the rolling element 5. When the number of crests of (nZ±1) exists, the rolling element on the opposite side is positioned at the bottom of the waviness the moment any rolling element 5 is positioned at the top of the waviness, and vibration occurs in the radial direction. The waviness of crests of more than (nZ+2) do not much affect vibration of both radial and axial directions.  Therefore, by specifying the number of crests of the waviness, it is possible to reduce irrotational synchronous runout.

Abstract: PROBLEM TO BE SOLVED: To utilize connection terminal and an ISDN trunk in a short time even when the connection terminal at the private branch of exchange side cannot start its restoration on the reception of an interruption message from an ISDN. SOLUTION: Upon the receipt of an 'interrupt' message from an ISDN 3, a central processing unit 10 identifies whether or not an information element of 'in-band signal available' is included in the 'interrupt' message and reads restoration start enable information from a restoration start enable information storage section 12. The central processing unit 10 discriminates the restoration start from a terminal equipment 2 to be 'disable' based on the information element of 'in-band signal available' and restoration start enable information, then the CPU 10 sends a 'release' message to the ISDN 3 via an ISDN trunk 15. Upon the receipt of a 'release end' message from the ISDN 3 in reply with it, the CPU 10 releases the terminal equipment 2 and the ISDN trunk 15.
