Title: Magnetic tape reproducing device
Inventor: KAWASHIMA OSAMU
IPC: G11B15/467
Filed: 1990-07-30
Abstract: PURPOSE:To indirectly detect the rotating speed of a cylinder and to reduce the thickness of the cylinder by extracting a clock signal synchronized with a regenerative signal from the regenerative signal reproduced by a magnetic head and generating a signal corresponding to a frequency deviation between this clock signal and a reference clock signal as a speed error signal. CONSTITUTION:The regenerative signal reproduced by reproducing heads 3a and 3b is amplified, while the clock signal synchronized with the regenerative signal is extracted from the regenerative signal, and the signal corresponding to a frequency change between this clock signal and the reference clock signal is generated as the speed error signal. By this method, the rotating speed of the cylinder 2 can indirectly be detected, and it is not necessary to fix a detector for detecting the rotating speed of the cylinder 2, and then the thickness of the cylinder can be reduced.

Title: Device and method for pen input, and computer-readable recording medium where pen input control program is recorded
Inventor: TADA SHIN
IPC: G06F3/0488
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To make a screen range choosable over two screens and to improve operability by deciding pen input operation which is not completed, but continuous between screens when pen input to a next screen is done within a specific time. SOLUTION: A timer clocks the time from the end of 1st input on an input screen 10a to the start of 2nd input on a 2nd input surface 10b and a judgement part judges whether or not the time clocked by the timer is longer than a specific time. When the clocked time is shorter than the specific time, an input control part recognizes the 1st input and 2nd input as one continuous input operation. Namely, when a touch pen 11a is put away from the screen 10a, a coordinate input device actuates the timer to measure the time up to the tracing of the pen 11a on the next screen 10b. When the screen 10b is traced within the specific time, it is judged that the input on the screen 10a with the touch pen 11a is not completed and a continuous process over the two screens is performed.

Filed: 1990-07-31
Abstract: PURPOSE:To improve the electric charging and discharging cycle characteristics of a nonaqueous secondary-battery by using as a binding agent for the positive electrode of the nonaqueous secondary-battery a material whose heat-resisting temperature is not less than the characteristic temperature and which has rubber elasticity. CONSTITUTION:A nonaqueous secondary-battery has a negative electrode using as its active material a material which can reversibly store and emit lithium or its ion, and a positive electrode having an intercalating type active material which can be reversibly charged and discharged with the lithium ion. As a binding agent for the positive electrode is used a material which has rubber elasticity and whose heat- resisting temperature is not less than 200 degrees Centigrade. A material being used for the binding agent is fluororubber consisting mainly of a copolymer consisting of hexafluoropropylene and vinylidene fluoride, or another fluororubber consisting mainly of a copolymer consisting of trifluorochloroethylene and vinylidene fluoride. Thus contact between the positive electrode active-material and a conducting agent or between the positive electrode and a current collector can be kept in its excellent condition so as to effectively use the positive electrode active-material without lowering the binding characteristic of the binding agent even if electric charge-and-discharge causes the expansion and construction of active-material grains.

Filed: 1992-07-30
Abstract: PURPOSE:To facilitate restitution to normal operation after the end of a transient phenomenon in a nuclear reactor by using only a condensate storage chamber during transient phenomenon using a logic circuit for changing over of refill water source. CONSTITUTION:A nuclear reactor containment 2 has a pressure vessel 1, dry well 3, and suppression pool 4, and the water in a condensate storage chamber 7 is refilled to the vessel 1 by a pump 8 in the condition that motor-driven valves 5, 6 are opened and shut, respectively, when the reactor water has sunk due to transient phenomenon in the nuclear reactor. Also when the reactor water is missing due to rupture of the piping, the refill water in the chamber 7 is supplied with the valves 5, 6 opened and shut. When the water level in the chamber 7 measured by a water level gauge 10 has become below the specified level, it is sensed and a low-level informing signal is emitted 11, and a logic circuit for changing over of water source turned open and shut the valves 5, 6, respectively, and thus changing-over of the refill water source takes place, and the pump 8 sends the water stored in the pool 4 into the vessel 1. During the transient phenomenon in the reactor, therefore, the water in the pool 4 will never flow into the reactor.
