Title: Input device of position information
Inventor: ONODA KATSUHIRO
IPC: G06F3/0488
Filed: 1980-10-24
Abstract: PURPOSE:To install an input device of position information of the information process system at an easy-to-use position for the free use, by installing a loop-shaped antenna at both sides of a tablet respectively. CONSTITUTION:Receiving loop-shaped antennas 30 and 31 are set at the right and left sides of a tablet 12. When an indication pen 23 is on one board face of the tablet 12, the reception signals of both antennas 30 and 31 produced by the radiated electric waves are added to each other to be supplied to a receiving part 36. In case the pen 23 goes beyond the antenna 30 or 31 and at a position outside the tablet 12, the reception signals of both antennas are offset to each other with the reverse  phase. As a result, the signals to be supplied to the part 36 is extremely attenuated  to be substantially O in case the space between the pen 23 and the tablet 12 is large enough compared with the space between the antennas 30 and 31. Accordingly no distrubance is given from other devices.

Title: Stepping motor control method
Inventor: SASAKI TSUTOMU
IPC: H02P8/00
Filed: 1990-06-11
Abstract: PURPOSE:To suppress fluctuation of rotation by varying the magnitude of current to be applied on one phase of a motor according to the number of excitation. CONSTITUTION:A clock signal repeats single phase excitation and two-phase excitation for every clock. Up and down signals are fed to a current control port, respectively, during single phase excitation interval and two-phase excitation interval according to the clock signal. In such a manner, a signal for regulating a current setting reference voltage through a transistor Tr3, as well as sequence data A, A', B, B' signals, are fed to the current control port. The signal goes Low during two-phase excitation interval and then goes High through an inverter I. Subsequently, the transistor Tr3 is turned ON to lower the current setting reference voltage which is set by means of voltage dividing resistors R1, R2, thus lowering the set current. During single phase excitation interval, the transistor Tr3 is turned OFF to increase the current setting reference voltage thus increasing the set current.

Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To easily adjust a flight distance by providing a touch sensor as integral part of the operation part of a flight distance adjustment means. SOLUTION: A shooting operation function part is formed out of a flight distance adjustment means as a touch sensor in common, and a flight distance display 21. Also, the flight distance adjustment means is formed so that a slide type variable resistor 17 is laid within a ball feed tray 5 and a operation part 18 of the resistor 17 is projected from the right surface of the tray 5. In this case, when the operation part 18 is moved right, a flight distance signal corresponding to the position of the operation part 18 is outputted from the variable resistor 17 to a shooting control device, thereby controlling a flight distance. In this way, the operation part 18 is formed to be the touch sensor in common, and the surface thereof is formed as a conductor, using a plating or deposition process.  At the same time, the operation part is connected to a touch switch circuit through a lead wire. According to this construction, current flows across the touch switch circuit simply when a player touches the operation part 18, and a touch signal is subsequently outputted, thus improving operability.

Abstract: PURPOSE:To restrict generation of hydrogen and prevent capacity of an alkaline- zinc storage battery from being lowered by plating a metal core with zinc and employing a current collector, which is composed by treating a portion of the plated zinc with ion displacement by the metal having oxidation-reduction potential and larger hydrogen overvoltage than those of zinc, as a zinc electrode. CONSTITUTION:A metal core is plated with zinc. A current collector which is composed by treating a portion of the plated zinc with ion displacement by the metal having oxidation-reduction potential which is more noble than that of zinc and hydrogen overvoltage which is larger than that of zinc is employed as a zinc electrode. Such as indium, thallium, cadmium, tin or lead may be employed as the metal having oxidation-reduction potential larger hydrogen overvoltage than those of zinc. The plated zinc is pure zinc, so that it is self-discharged and hydrogen is generated. Accordingly, when the portion of the plated zinc is treated with ion displacement by the metal having larger hydrogen overvoltage, the generation of hydrogen from the portion of the zinc where is plated is completely restricted.
