Title: Selection device for data circuit
Inventor: KAMITSUMA MAKOTO
IPC: H04M11/00
Filed: 1992-07-15
Abstract: PURPOSE:To unnecessitate an ordinary exchange or an exchanging function, to reduce cost and to reduce noise by adding a DC voltage to a facsimile equipment only when the facsimile equipment is cut off from a telephone circuit. CONSTITUTION:When no current is made to flow to a line (1), the state is detected at a current detection part inside a switching part 13 and the information of line usage permission is transmitted through a line control part 3 to a data control part 2. Then, when the line (1) and the line (3) are connected at the switching part 13, control signals are transmitted from the data control part 2 which detected the state through the line control part 3 to a facsimile calling part 11 so as to make access to an NTT network correspondence facsimile equipment 7. Thereafter, when the NTT network correspondence facsimile equipment 7 is called and the DC voltage is added simultaneously, the facsimile equipment monitoring the voltage and the current is made correspondable even when it is used as the NTT network correspondence facsimile equipment 7 so that the NTT network correspondence voltage is applied from the line control part 3 to a voltage impressing part 12.

Title: Lead frame for semiconductor device
Inventor: TAJIMA TAKAHIRO
IPC: H01L21/52
Filed: 1987-07-27
Abstract: PURPOSE:To prevent a melted solder from scattering onto a lead frame, the solder from creeping to a die pad lead and to prevent a hanging lead bent part from rising or a die pad from inclining by composing the die pad in a tray-like state capable of containing a semiconductor chip. CONSTITUTION:A die pad 10 is composed in a tray-like state becoming the same plane as the upper end of a lead frame 9, while the frame 9 is bonded to a chip 5 by melting solder 6 on the pad 10, and the upper face of the chip 5 is bonded by a connecting metal fine wiring 7 to the end of an inner lead 11. Accordingly, since the chip 5 is contained in a tray-like die pad, the solder is prevented from flowing, thereby preventing the melted solder from scattering to the surfaces of the frame 9, the lead 11, the hanging lead 12 and creeping on the die pad 2a.

Title: Device and method for digital lock detection for phase locked loop
Inventor: REBUAIN SUTEIIBUN ENU
IPC: H03K5/13
Filed: 1991-07-02
Abstract: PURPOSE: To precisely make a lock instruction by using a phase-locked loop that has an input signal and an output signal and generating a lock detection signal in response to a relative phase of the input and output signals of the phase-locked loop. CONSTITUTION: Programmable control signals Y and Z which are outputted from a bandwidth control circuit 20 control a loop operation frequency. A composite substrate clock signal is connected to a divider 16 through a phase and frequency adjusting circuit network 12. For instance, 1.92 MHg clock reference signal is given, the divider 16 gives 6000 Hg loop operation frequency without the other operations and therefore, a multiple frequency DPLL circuit performs 6000 correction per second. Further, dividers 26 and 28 are connected to 1.92 MHg reference clock and an AND gate 30 and give an output signal that can be some possible frequencies based on the signals Y and Z. In this way, when the circuit network 20 adds or subtracts 6000 pulse/second to/from the reference clock signal, a phase-locked loop can compensate for phase noncoincidence.

Title: Four-wheel steering gear for vehicle
Inventor: KANAZAWA HIROTAKA
IPC: B62D7/15
Filed: 1982-10-26
Abstract: PURPOSE:To enhance operability of a four-wheel steering gear at intermediate and high vehicle velocities, by providing a controller for controlling a rear-wheel steering gear in accordance with rear-wheel steering angle characteristics relative to a front-wheel steering angle. CONSTITUTION:Front wheels 1, 1 and rear wheels 2, 2 are mechanically separated from each other, an output 4a from a front-wheel steering angle sensor 4 detecting a steering angle thetaH of a steering wheel 3 is inputted into a controller 10 for the rear-wheel steering gear, and the rear wheels 2, 2 are steered by the input signal. A point of inflection P1, P2... at which a steering ratio thetaR/thetaF is reduced is varied toward a smaller front-wheel steering angle thetaF as the vehicle velosity is increased, so that a G range is reduced with an increase is the vehicle velocity, and the rear-wheel steering angle thetaR reaches a limit value theta'R for a small front-wheel steering angle thetaF, thereby enhancing operability. In addition, a higher steering ratio is obtained for a higher vehicle velosity, whereby response characteristic at the time of a lane change at an intermediate or high vehicle velocity is enhanced.

Title: Circuit for detecting fault of diode switch
Inventor: YAJIMA YASUO
IPC: H04B17/00
Filed: 1989-07-20
Abstract: PURPOSE:To surely detect any kind of fault of a diode by detecting a beat frequency component generated at a time when transmission output from two transmitters are mixed and sent to an antenna due to the fault of a diode switch. CONSTITUTION:When the diode of the diode switch 3 is deteriorated, etc., and its impedance is changed, the transmission output (input 1, input 2) from the transmitter cannot be blocked with a diode D1 or D2. Consequently, the transmission output (input 1, input 2) from the two transmitters are mixed and outputted from an output terminal P0 to an antenna feed line 7. The fault of the diode can be detected by detecting a beat signal generated at such a case with a detector 6 and a beat frequency component detecting part 9. In such a manner, the fault of the diode can be completely detected extending over a wide range.

Abstract: PURPOSE: To provide a game machine capable of expressing a state of the inner structure being subjected to attack viewed from outside, by displaying an outer mechanical object before it is subjected to attack and an inner mechanical screen by a part of outer object when subjected to attack. CONSTITUTION: Once the program for a CPU 2 circuit starts, the images for an interior mechanical screen (A) are stored in a screen memory 4c. Then, an exterior mechanical objects (B) are stored in a buffer memory 3c with separating the object into plural parts.

The priority of the exterior mechanical objects is placed over that of the exterior mechanical screen, and thus the exterior objects are displayed on a CRT equipment 6. This is the state that an enemy is not shot yet. Once the enemy is shot, a through object C is overlapped on the exterior mechanical object B, and thus the priority of the part of the exterior mechanical objects is reduced and the interior screen of the point is displayed.

Title: Paper sheet feeder
Inventor: IWASHITA YOSHIHARU
IPC: B65H5/02
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To ensure that a paper sheet loaded into a paper sheet loader into which paper sheets such as bills are loaded is fed even while another paper sheet passes through the loader by providing an auxiliary drive mechanism inside the loader. SOLUTION: When a bill S1 passing through a bill loader B is detected by an upstream side sensor 60, the rear end of another bill S2a loaded is put into a waiting position along the outer periphery of an upstream side feed belt 9 by the bill holding mechanism 55 of a bill discriminator. As the passing bill S1 comes in, it is brought into contact with the round belt 47 of a pulley 44 by an auxiliary drive mechanism 43 and fed up to its rear end while slipping on the waiting bill S2a. Then the bill S2a comes into contact with the feed belt 9 and the round belt 47, but is not fed while overlapping with the passing bill S1 since its rear end is held by the holding mechanism 55. When the rear end of the bill S1 is detected by a downstream side sensor 70, the holding mechanism 55 for the bill S2a is released, and the bill S2 is fed continuously.
