Title: Telephone set
Inventor: YUKI TAKAYUKI
IPC: H04M1/67
Filed: 1993-01-26
Abstract: PURPOSE:To restrict implementation of an expensive long distance call from an external remote commander through a handset. CONSTITUTION:When a handset 6 is lifted up and an off-hook signal is outputted from a hook switch 7, a CPU 8 outputs an internal off-hook signal to close a line switch 1. When a telephone number is entered from a key board 9, the CPU 8 checks its 1st digit and outputs an internal on-hook signal in the case of '0' to open the line switch and keeps a line loop as it is in other cases to attain dialing. On the other hand, when a DTMF signal corresponding to the telephone number is inputted from a DTMF generator 12 via a transmitter 6, A DTMF receiver 13 decodes its 1st digit and sends it to the CPU 8 and when it is '0', the CPU 8 outputs an internal on-hook signal to open the line switch 1 and in other cases, the line loop is kept as it is to attain dialing.

Title: Optical fiber communication method and optical fiber communication network using frequency multiplexing
Inventor: ORIBIE ODOUAN
IPC: H04B10/27
Filed: 1992-01-24
Abstract: PURPOSE: To obtain optical fiber communication method, using frequency multiplexing processing and the optical fiber communication network. CONSTITUTION: Transmission frequencies (F(1)...F(2P)) used for simultaneous communication are formed as a stack from a prescribed base frequency F(0), to be reached to stack apexes (F(2P-1), F(2P)). A transmission frequency (F(2P-1)) used for a communication at start of each communication exists at an apex of the stack. When a subordinate base frequency (F(2P-2)) is detected during communication, the transmission frequency is kept at a high order by a prescribed spectral difference(DF) from the suborbinate base frequency by a servo control. Conversely, the transmission frequency is gradually shifted towards the base frequency. The method is used especially for communication between peripheral equipment of information systems.

Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To provide an electronic equipment having a function which automatically detects the deterioration of an integrated circuit used inside. SOLUTION: An electronic equipment 10 is operated when a power supply voltage v11 is supplied from a power source 11 in a normal using state. Afterwards, the electronic equipment 10 is turned into the self-diagnostic mode of a voltage margin before a power source is turned into an off state. At that time, a self-diagnostic instruction for decreasing the power supply voltage v11 is outputted from a controlling part 12, and the power supply voltage supplied to the controlling part 12 is made lower than the output voltage v11. Afterwards, the self-diagnosis of an IC in the controlling part 12 is operated, and when it is confirmed that it is normal, the processing is ended as it is, and the power source is automatically turned into the off state.  On the other hand, when a self-diagnostic error is generated at the time of the decrease of the power supply voltage supplied to the controlling part 12, the generation of the self-diagnostic error is displayed by a failure generation recording part 14. Then, an operator makes a maintenance exchanging request for preventing the fault of the controlling part 12.

Filed: 1986-01-22
Abstract: PURPOSE:To attain the complete pull-in even in a narrow band PLL by adding together the outputs of both 1st and 2nd phase comparators and smoothing these added outputs to send them to a voltage control oscillator in the form of the frequency control voltage. CONSTITUTION:The frequency error discriminating output is obtained at the output of the 2nd phase comparator 15 and the detecting signal of the phase error (double) is obtained at the output of the 1st phase comparator 16 respectively. In an asynchonizing mode, the frequency error discriminating signal passes through an LPF 19, an adder 17 and an LPF 18 to control the frequency and controls the frequency error within the synchronizing range of a PLL. While the phase synchronizing operation is carried out through the PLL consisting of the comparator 16, the adder 17, the LPF 18 and a VCO 1 in a synchronizing mode. That is, the frequency error is compressed by an automatic frequency control action carried out based on the frequency discriminating action in an asynchronizing mode. Thus the complete PLL pull-in is attained.

Title: Focus detector
Inventor: ISHIDA TOKUJI
IPC: G03B3/00
Filed: 1988-01-21
Abstract: PURPOSE:To omit the insignificant setting of the position of a lens by driving a lens to an initial stopping position at the time of deciding that it is under condition that the driving of the lens should be performed in a condition decision means. CONSTITUTION:The initial stopping position Ns of the lens 1 is determined by a lens position determining means 3 in order to make probability that the focus detection can be possible high. And the condition decision means 5 decides whether or not the lens 1 is under the condition that the lens 1 should be driven to the initial stopping position Ns. Now, for example, a time when a main switch SM form power source is turned on is considered as the condition. In such a case, a control means 6 controls a lens driving means 4 so that the lens 1 is driven to the initial stopping position Ns. Thus, the initial setting of the position of the lens is performed under the specified condition and the probability that the focus detection can be possible is made high. Since the initial setting of the position of the lens is not performed when it is not under the specified condition, the quantity of current consumption can be reduced.

Inventor: TONE KAORU
IPC: H05K3/24
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To form gold-plated films of different thicknesses by a single electrolytic gold plating operation, by dipping a board in a gold plating solution containing floatable insulators, and performing electrolytic gold plating making the pressure of the solution being applied to a surface having bonding pads of the board higher than that of the other surface. SOLUTION: A gold plating solution 3 contains insulators 4 larger than the inside diameter of a through hole metal film 14, and floatable in the gold plating solution 3. If the height of the liquid surface of the gold plating solution 3 on the side of a surface A to be bonded is made higher than that of the gold plating solution 3 on the side of the other surface B, the solution pressure being applied to the surface A to be bonded becomes higher than that to the other. As the result, thicker gold-plated film 15 are formed on the surfaces of bonding pads 121 to which larger amounts of gold-plating solution flow, and thinner gold-plated films 15 are formed on the surfaces of the through hole metal film 14 and lands where smaller amounts flow. Accordingly, it becomes possible to form gold plated films of different thicknesses in a single electrolytic gold plating operation.

Title: Conveying passage control unit
Inventor: OMIYA TETSUO
IPC: B65G43/08
Filed: 1985-01-25
Abstract: PURPOSE:To improve efficiency so high as well as to reduce a noise to the smallest possible extent, by dividing a conveying passage into some parts, and driving each of these divided conveying passages with each state signal out of all apparatuses related. CONSTITUTION:When feeder 20 is operated, first of all, an operation signal is transmitted to a control unit 50 from the feeder 20. The control unit 50 receives the operation signal out of the feeder 20, taking in each state signal out of an accumulation device 40 and conveying passage trouble detectors 21 and 31 and, after making sure that there is no trouble, transmits an operation command signal to the accumulation device 40. Furthermore, the control unit 50 makes sure that it receives the operation signal of the accumulation device 40 and transmits the operation command signal to driving parts 32 and 22 in order. The control unit 50 receives each operation signal out of these driving parts 32 and 22 and thereby transmits a feed 'yes' signal to the feeder 20. The feeder 20 receives the said feed 'yes' signal and feeds a common conveying passage 62 with an object. Since the irreducible minimum of conveying passages alone operates, a noise is little and each conveying passage is driven by each state signal out of related apparatuses so that efficiency is high enough.

IPC: H01L21/8222
Filed: 1998-01-07
Abstract: PROBLEM TO BE SOLVED: To provide the NPN transistor driving circuit of high output current ability and a fast switching speed. SOLUTION: When a first transistor 1 is turned to a conductive state and a second transistor 2 is turned to the conductive state, the potential of the pinch layer of a pinch resistance element 10 is raised, a pinch resistance value becomes large and thus, a current flowing to the pinch resistance element 10 is reduced and the current flowing to the base of the second transistor 2 is secured to be large. On the other hand, when the first transistor 1 is turned to a non-conductive state, since the potential of the pinch layer of the pinch resistance element 10 is lowered roughly to a ground potential, the resistance value of the pinch resistance element 10 is lowered and electric charges stored in the base of the second transistor 2 are discharged in a short time.
