Title: Manufacture of electrode for battery
Inventor: YANAGIHARA NOBUYUKI
IPC: H01M4/02
Filed: 1988-03-30
Abstract: PURPOSE:To extend the service life and the charge-discharge cycle life by melting and fixing metallic particles on the surface of an electrode supporting body, applying an electrode constituting material or an active substance on that surface, and making them in a body by pressing. CONSTITUTION:Paste-like metallic particles 3 are melted and fixed on the surface of an electrode supporting body. An electrode constituting material 1 or an active substance is applied to sandwitch the supporting body which is then pressed to be made into an integral body. Because the metallic particles 3 are melt-fixed on the surface of the electrode supporting body, the metallic particles 3 are firmly combined with the electrode constituting material 1 or the active substance on the surface with a strong adhesiveness. As a result, the contact resistance between the two components is small and the separation phenomenon between them is reduced. As a result, the electrode can extend the life of a fuel cell and extend the cycle life of hydrogen storage electrode and a nickel oxide anode.

Filed: 1983-04-30
Abstract: PURPOSE:To produce a highly reliable identification card which is hardly affected by defective contact and magnetism by generating an identification signal in accordance with presence or absence of shields buried in the card. CONSTITUTION:In case magnetic shields 2 and 3 are buried in positions A and D out of positions A-D in a card body 1 and are read by a reader, coils 11-14 are excited by an AC power source 15 to generate an alternating field. Though this alternating field is received by coils 21-24, only coils 22 and 24 generate an electromotive force because magnetic shields 2 and 3 exist, and this electromotive force is read by a reading circuit 25. The read digital signal is ''0101''.

Title: Charging circuit for telephone communication terminal
Inventor: TOYAMA TETSUYA
IPC: H04B7/26
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To enable satisfactory power supply from a secondary battery and to satisfactorily operate various functions, even when many calls are originated from a telephone communication terminal by charging capacitor and charging the secondary battery from the capacitor, while utilizing the incoming signal current of a high voltage, not only when the telephone communication terminal is not used or is used but also when an incoming signal is detected by the telephone communicating terminal.

Thus, the incoming signal current of the high voltage (220 VPP) flowing to the telephone lines L1 and L2 is rectified to a DC current by the rectifying bridge 2 and supplied to the capacitor 8 later, and the capacitor 8 is charged quickly. When the incoming signal current does not flow any longer, the capacitor 8 is discharged, the discharging current is supplied to a secondary battery 5 and the secondary battery 5 is charged.

Title: Shaft for golf club and production thereof
Inventor: TAMASU SHII UORUTAN
IPC: A63B53/10
Filed: 1990-03-28
Abstract: PURPOSE: To select a kick spot of shaft and intensify the section of the shaft by comprising an epoxy polymeric parent body having the angle of 30 deg. to 45 deg. between a strand against the longitudinal axial line of the shaft intensified by an intensified strand woven by an aramid fiber and a carbon/graphite fibers composed, and using a composite material having a ore light weight and a more higher rigidity. CONSTITUTION: An intensified organic fiber and the parent body improve the feeling of the golf club of damping the oscillation. For example, when an adjusted shell consisting of the intensified epoxy parent body with an increased rigidity by 50vol.% of an intensified aramid fiber and 50vol.% of graphite/carbon fibers-woven intensified strand is used, the aramid fiber composite provides a more higher damping ratio than the graphite/carbon intensified composite, therefore, a structural rigidity and the damping action of the oscillation is obtained. These strands is made so as to put the angle of 30 deg. to 45 deg. against the longitudinal axial direction of the shaft. By this feature, the comparatively economical saving of a weight can be realized by adjusting the kick point of the shaft by modifying a steel-made or the other metallic-made shaft.

Title: Temperature controller for copying machine
Inventor: SUDOU TOSHIHIKO
IPC: G03G15/20
Filed: 1982-05-08
Abstract: PURPOSE:To prevent the safety of the temperature sensor of a heat fixing device from degrading during a breakdown by stopping copying operation after discharging copying forms remaining in a passage when it is judged that the breaking of wire occurs to a fixing device temperature detection part. CONSTITUTION:If the breaking of the sensor 1 or sensor lead wire occurs during the operation of the copying machine, a microcomputer 20 outputs a control signal to a driving group 40 to inhibit forms from being fed from a form dish and if there is a form in the passage near the fixing device, the form is discharged by carrying on the copying operation and then the machine stops. When there is no form in the passage, the machine stops operating immediately. For this purpose, a heater 33 is turned on the off under control based upon the output of an AND circuit 4, but microcomputer control may be employed. The heater 33 is provided in a heat roller 31 contacting the presser roller 32 of a fixing part E. The sensor 1 uses a thermistor, etc., which decreases in resistance value according to a temperature rise.

Title: Electromagnetic device
Inventor: KAKEHASHI HIDENORI
IPC: H01F29/10
Filed: 1988-03-28
Abstract: PURPOSE:To increase the variable amount of inductance by a method wherein a wire- wound bobbin is provided, and recessed and protruding parts, which will be attached to said bobbin by being pinched from both ends, are formed side by side in the circumferential direction on the butt-together surfaces of the inner magnetic path and the outer magnetic path. CONSTITUTION:Pot cores 11 and 12 are composed of inner magnetic paths 13 and 15, which pass through a bobbin 10, and the outer magnetic paths 14 and 16 which are externally fit to the bobbin 10. The butt-together surfaces 17, 18, 19 and 20 of the inner magnetic paths 13 and 15, and the outer magnetic paths 14 and 16 are divided into two parts of protruding parts 21, 23, 24 and 25, and recessed parts 22, 24, 26 and 28 in circumferential direction. As the distance between magnetic bodies becomes smaller and an opposing area becomes wider, the magnetic reluctance becomes smaller; the magnetic reluctance becomes larger in the order of the state of theta=0 deg. (the state wherein the protruding parts 21 and 25, and the protruding parts 23 and 27 are opposingly positioned) theta=90 deg. and theta=180 deg., while the inductance becomes lower. At the same time, the variable amount of inductance is increased compared with the case of the where the recessed and protruding parts are formed only in the inner magnetic parts as by the method heretofore in use.

Title: Frequency characteristic equalizer for loudspeaker system
Inventor: KURIYAMA JOJI
IPC: H04R3/04
Filed: 1988-03-29
Abstract: PURPOSE:To obtain a desired amplitude/phase frequency characteristic at a wide listening area with high accuracy by providing an adaptive digital filter section applying self-adjustment such that the square means value of error signals are minimized. CONSTITUTION:An input signal is retarded by a prescribed time only at a delay circuit section D and sent to an error detection section 11 through a filter section G having a desired amplitude phase frequency characteristic. On the other hand, an output signal from plural reception microphones M1-Mn is subjected to weighting processing and the result is inputted to an error detection section 11. The error detection section 11 subtracts total sum signal of sound reception microphone output signals from the output signal of the filter section G and sends the result to an adaptive digital filter section M as an error signal. The adaptive digital filter section H applies self-adjustment so that the square mean value of error signals is minimized. Thus, the sound pressure frequency characteristic in the listening area where the sound reception microphones M are installed is subjected to correction and equalization with high accuracy so that it is nearly equal to the frequency characteristic set to the filter section G.
