Title: Lithium secondary cell
Inventor: KOISHIKAWA YOSHIMASA
IPC: H01M10/0525
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a lithium secondary cell which can improve a charging/ discharging cycle life and a life on storage. SOLUTION: A negative electrode applying as a negative electrode active material an amorphous carbon material with a irreversible capacity of not less than 5% to not more than 25% of primary charging capacity to a rolled copper foil and a positive electrode applying as a positive electrode active material an aluminum foil and lithium manganate are used, a discharging ratio of the negative electrode to the positive electrode (-/+ ratio) after primary charging is adjusted to not less than 1.3 to not more than 1.8 by adjusting an applying amount (thickness) of the positive electrode active material and a Li/Mn ratio in the positive electrode material is adjusted to a range of 0.55-0.60.  As a degree of discharging of the positive electrode is lower to a degree corresponding to the irreversible capacity, deterioration of the positive electrode can be controlled, and as a utility ratio of the negative electrode is low and a deterioration of the negative electrode can be controlled because of an excess of negative electrode active material.

Title: Keyboard musical instrument
Inventor: KAWAMURA KIYOSHI
IPC: G10H7/00
Filed: 1990-11-27
Abstract: PURPOSE:To improve timbres and sound volume by calculating the vibration state of a tensed string and a virtual string of the same interval as this tensed string in accordance with the line spectrum indicating the vibration state of the tensed string, converting this state to a sound and producing the sound after the prescribed time set shorter than the audible identification time from the sounding time of the tensed string. CONSTITUTION:The sound corresponding to the tensed string 11 is produced if this string 11 is struck. A detecting means 12 simultaneously detects the vibration state of the tensed string 11 and a calculating means 13 calculates the vibration state of the virtual string of the same interval as the interval of this tensed string 11 in accordance with the ray spectra indicating this vibration state. The sound producing means 14 produces the sound by converting the vibration state of the virtual string to the sound. The sound producing means 14 produces the sound within the time shorter than the audible identification time after the sound producing by the striking of the tensed string 11 in such a case. The sound produced by the tensed string and the sound produced by the virtual string are eventually simultaneously audible to a listener. Both the timbres and sound volume of the sound produced by a key touch are improved.

Title: Axle body suspension truck using magnetic force
Inventor: YAMAGUCHI HIROSHI
IPC: B61F5/30
Filed: 1987-12-23
Abstract: PURPOSE:To improve vibration isolability and riding quality as well as to improve curve passability, by using magnetic force for the transfer of body load from a truck to an axle box. CONSTITUTION:Power is supplied to a superconductive coil magnet 5 till a truck frame 2 comes to floatage by repulsion of the magnet and an axle box 3 comes into a state of being supported in a noncontact state in all directions to the truck frame 2. When a superconductive switch 10 is closed in this state, a permanent current flows in the superconductive coil magnet 5, whereby the truck frame 2 maintains a floatage and noncontact state with the axle box 3. Accordingly, vibration isolability against vibrations in a wheel 4 higher than the truck frame 2 is remarkably improved and thereby riding comfort is enhanced. In addition, there is no frictional sliding part, and thus an axle box suspension system with improved maintainability is realizable.

Title: Iron core type reactor with gap
Inventor: ISAKA SUSUMU
IPC: H01F27/24
Filed: 1990-11-27
Abstract: PURPOSE:To reduce loss in a magnetic block itself in order to lower eddy current loss and stray loss due to leakage magnetic flux by inserting a magnetic block formed by sintering magnetic material powder to cover a winding between the end part of iron core legs and yoke iron core. CONSTITUTION:Iron core legs 3 with gap are formed by stacking a plurality of block iron cores 1 with a magnetic gap 2 and plate type magnetic blocks 9a, 9b obtained by sindering and molding magnetic material powder are sandwiched from upper and lower yoke iron cores 5a, 5b at the upper and lower ends of the iron core legs 3 to cover a winding 6 together with the right and left side legs 4. Therefore, a volume resistivity of magnetic blocks 9a, 9b is as large as 10<6> or larger and an eddy current loss can be neglected for the magnetic flux of commercial frequency range. Accordingly, overheat of the magnetic blocks 9a, 9b are not considered as a problem and sufficiently plays a role for uniformly applying the magnetic flux in the ununiform distribution from the block iron core 1 and winding 6 to the yoke iron cores 5a, 5b. Thereby, loss in magnetic block itself is reduced and eddy current loss, stray loss due to magnetic flux can be lowered.

Title: Circuit and method for detecting maximum amplitude of three-phase signal
Inventor: MATSUYAMA YASUHIKO
IPC: G01S3/808
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To surely detect maximum amplitude of three-phase signals. SOLUTION: Three-phase signals are converted into digital sampling data by means of A/D conversion circuits 11, 12, and 13 and inputted to a comparison means 21 in an appropriate sampling period. The means 21 checks whether or not the values of any two of the three signals match with each other, by comparing the sampling data of the signals utilizing such properties of three- signals, that when the amplitude values of any two of the three signals match with each other, the amplitude value of the remaining one signal can be set the maximum amplitude of the signals. When matching is detected, a maximum amplitude deciding means 22 records the sampling data of the remaining one signal as the maximum amplitude value or outputs the data to the next processing block.

Title: Contactless signal coupler and electronic apparatus system
Inventor: NOZAKI HIROSHI
IPC: B43L1/04
Filed: 1994-12-27
Abstract: PURPOSE: To improve the transmission efficiency of a signal coupler using a sheet coil and to make progress of the performance of an electronic apparatus system having such a coupler by providing a magnetic sheet having high permeability on the back surface side of the coil. CONSTITUTION: Even if an interval between sheet coils 5a and 6a is the same as that between contactless signal couplers 5 and 6, the quantity of a magnetic flux which can pass the coil of the secondary side of that generated from the coil of the primary side, i.e., electromagnetic bonding force is remarkably increased since the sheets 5b, 6b of high permeability materials are extended to the back surface of the coils. Thus, a signal transmission gain between the coils 5a and 6a is increased, and the power level of the signal obtained from the coil of the secondary side is increased. Since the sheets 5b, 6b perform functions of magnetic shields for covering the back surface side with respect to the coils 5a, 6a, it is scarcely affected by the electromagnetic noise, whereby the S/N ratio is improved.

Title: Damper opening and closing device
Inventor: TSUJIMOTO AKINORI
IPC: F25D17/08
Filed: 1990-11-29
Abstract: PURPOSE:To simplify the structure of the title device by a method wherein a rotor is stopped at every inlet port of cold air and the outlet port of the same while the cold air inlet port and the cold air outlet port are blockaded by a damper and the flow of cold air to the outlet port is guided by the projected part of the rotor. CONSTITUTION:An outlet port 15a is communicated with a first chamber and another outlet port 15b is communicated with a second chamber while a rotor 19 is stopped at a position whereat a damper unit 19b closes the inlet port 14 of a housing to blockade the inflow of cold air from a cold air discharging port when the temperatures of both chambers are low, for example. When only the temperature of the second chamber is high, the rotor 19 is turned clockwise by 90 deg. whereby the outlet port unit 15a is closed. In this case, the cold air, entered through the discharging port, flows out of the outlet port 15b into the second chamber along the recessed curved surface 19e of the projected part 19e of the rotor 19. According to this method, the temperature control of two chambers can be effected by a single rotor 19 whereby the structure of the captioned device can be simplified.
