Title: Lithium ion secondary battery
Inventor: AMEZUTSUMI TORU
IPC: H01M10/0525
Filed: 1992-02-28
Abstract: PURPOSE:To increase the energy density of a lithium ion secondary battery by causing negative electrode carbon to store the lithium of lithium salt solution added to an electrolyte via a charging process. CONSTITUTION:When lithium as a component corresponding to the first charge and discharge capacity is released from the lithium salt solution of an electrolyte and stored by a negative electrode, a lithium amount released from an active electrode material and stored by the negative electrode becomes roughly equal to a lithium amount released from the negative electrode to a positive electrode. It follows, therefore, that a difference of lithium amounts released from both active and negative electrode materials can be reduced, and a compensation can be made for a loss in charge and discharge capacity. This lithium salt solution added to the electrolyte is electrically resolved, and becomes gas at the positive electrode. Consequently, a reset type relief valve 1 is provided to discharge gas from the inside of a battery. This valve 1 clamps a sealing plate 4 via a gasket 3 on the upper end opening of an externally mounted can 2. A valve port 5 is formed at the center of the plate 4 and closed with a valve seat 6. This seat 6, however, is pushed up with gas pressure, and gas is thereby discharged outside.

Title: Multi-channel information device
Inventor: TOKORO KIYOUSUKE
IPC: G06F3/06
Filed: 1989-02-23
Abstract: PURPOSE:To reduce or eliminate the added quantity of data by adding the control information on the additional data, a direction pointing signal, etc., into the conversion table data and outputting the control information together with a real address signal via an address conversion means. CONSTITUTION:An address conversion means 21 which performs the conversion of addresses for an access to a buffer memory 3 outputs the control information together with a real address signal. In other words, a real address signal is outputted to give an access to a specific channel and at the same time the requested control information is outputted to the specific channel via the same address as the real address signal of the means 21 at input of a virtual address signal 8a. A control means receives the requests from each channel and produces previously the due conversion table data 20a to store it in the means 21. Thus both the real address signal and the control information are simultaneously outputted in the timing for input of the signal 8a. Then the control actions are attained with accurate synchronization.

Title: Optical transmission system
Inventor: TSUCHIYA TOSHIYUKI
IPC: H04B10/2507
Filed: 1991-03-08
Abstract: PURPOSE:To avoid degradation in the quality of a signal by changing the frequency band of a transmission signal so that intermodulation secondary distortion due to the added frequency is caused at a frequency higher than a transmission band and secondary distortion due to difference frequency is caused at a frequency lower than the transmission band. CONSTITUTION:A signal (d) is converted into an optical signal by a synthesizer 11, a signal generator 12, an HPF 13 and an amplifier 14 and transmitted so that intermodulation secondary distortion (f1+f2) by carriers f1, f2 is set to a frequency higher than a transmission band and intermodulation secondary distortion (f60-f1) by carriers f1, f60 is set to a frequency lower than the transmission band. The frequency band of the signal (d) is set to 490-868MHz, then the intermodulation secondary distortion (fn+fa) is set to 988.5MHz or above and the secondary distortion (fn-fa) is selected to be 354MHz or below so that they are not overlapped with the transmission band while holding a sufficient guard band therebetween. Thus, even when the analog optical signal (e) of 1.55mum is transmitted through an optical fiber cable 21 whose zero dispersion wavelength is 1.3mum, the transmission signal (a) is not affected by the intermodulation secondary distortion.

Title: Supply voltage detecting circuit
Inventor: TABATA JIYUNICHI
IPC: G01R19/165
Filed: 1978-04-14
Abstract: PURPOSE: To constitute the supply voltage detecting circuit completely in IC, by forming the detecting circuit with reference voltage generating circuit, supply voltage dividing circuit, and voltage comparator circuit.  
     CONSTITUTION: When a reference voltage generating circuit A is formed with P type MOS transistor TR1 and N type MOS transistor TR2, and resistance 3, potential Vs at point a is the sum of threshold voltage VTP of TR1 and threshold voltage VTN of TR2. Even if the voltages VTP, VTN fluctuate individually, such discrepancy is canceled and the sum is always stable. A voltage comparator circuit B consisting of P type MOS transistors TR4, 6 and N type MOS transistors TR5, 7 has two input terminals, of which one is connected to point (a) and the other to contact (b) of resistances 8, 9. By properly selecting the resistances 8, 9, when the battery reaches the life end voltage, an output is delivered from the comparator circuit B, so that the life of the battery may be detected. Thus, since the effect of variation in IC process of each circuit and temperature coefficients may be kept to a minimum, the circuit may be completely designed in IC.

Title: Gutter elbow
Inventor: FURUBAYASHI KEIZOU
IPC: F16L43/00
Filed: 1978-04-15
Abstract: PURPOSE: To make a gutter easily executable to any place where conventional elbows cannot serve well, without sacrificing the draining performance, by using flexible tubes for connecting gutter cylinders.  
     CONSTITUTION: Bottom plates of two gutter cylinders 1a, 1b have water holes 3 which are opposed to each other and communicated by means of L-shaped flexible tubes 4. Consequently the angle between the cylinders 1a, 1b is easily adjustable, by virtue of the flexible tubes, to any situation where conventional elbows cannot serve for fitting a gutter. Since the nest of flexible tubes 4 is smaller than the cylinder 1 in diameter, its cross section is not reduced even if its form is changed and accordingly its draining performance is not lowered.

Title: Magnetic recording medium and its production
Inventor: KITAGAMI OSAMU
IPC: G11B5/73
Filed: 1986-02-28
Abstract: PURPOSE:To reduce noise and to permit high-density recording by providing a thin ferromagnetic metallic film layer on a soft magnetic underlying layer on a substrate and decreasing the content ratio of the nonmagnetic element to cobalt in the thin ferromagnetic metallic film layer gradually toward the boundary face with the soft magnetic underlying layer from the surface. CONSTITUTION:The vapor of the cobalt flows mainly in the perpendicular direction and is directed to the substrate 8 and the vapor of the nonmagnetic element flows mainly in the incident direction of an electron ray A and is directed toward the substrate 8 when the electron ray A is made incident at a sharp incident angle theta and a ferromagnetic material 14 is heated to evaporate. As a result, the thin ferromagnetic metallic film layer formed by the deposition of the vapor flow of the ferromagnetic material on the substrate 8 is formed with such a concn. gradient at which the content ratio of the nonmagnetic element to the cobalt decreases gradually toward the boundary face with the soft magnetic underlying layer from the surface. The tin ferromagnetic metallic film layer having the satd. magnetization quantity lower on the surface and higher toward the soft magnetic underlying layer is thus formed. The generation of inverse magnetic domains is thereby suppressed, the reproduction output is improved and the noise is suppressed.
