Patent JP-H042160-A (JP)
Title: Integrated circuit
Inventor: TAKEDA YOSHINORI
IPC: H01L29/732
Filed: 1990-04-18
Abstract: PURPOSE:To prevent overcurrent and malfunction due to e drop in a first source voltage by connecting the first source voltage with an isolated potential region through a high-value resistor. CONSTITUTION:An isolated potential region 38 is connected to a first source voltage through a high-value resistor. If the source voltage drops or becomes zero because of a failure, the potential region 38 is maintained at a high voltage through the resistor 44. Consequently, the bass-emitter junction of a parasitic pnp transistor 42 is not biased, thus preventing overcurrent flowing from emitter to collector in the parasitic transistor.

Filed: 1987-04-24
Abstract: PURPOSE:To prevent deterioration of a sensor by a detected voltage by providing a voltage control means for decreasing the voltage to be impressed to the metal oxide semiconductor of an exhaust gas sensor in a region where the resistance value of the sensor drops extremely. CONSTITUTION:A load resistance R1, resistances R2, R3 for setting the detection levels of an air-fuel ratio, and reference resistance R4, R5 for discriminating whether the interruption of a power supply is needed or not are connected to the exhaust gas sensor 6 consisting of the n-type metal oxide semiconductor. The intermediate voltage of a rich level and lean level is taken out by the resistances R2, R3 and whether the air-fuel ratio is rich or lean is discriminated. The output corresponding to the rich level is taken out by the resistances R4, R5 and whether the sensor output is above said level or not is discriminated. Whether the resistance value of the sensor 6 drops down to the value below the resistance value determined by the reference voltage or not is detected in such a manner and the drop of the resistance value of the sensor 6 below the above-mentioned value is adopted as the condition for cutting the detection voltage.

Title: Method of winding sheet band
Inventor: NAGAHATA KUNIYOSHI
IPC: B65H19/26
Filed: 1983-06-08
Abstract: PURPOSE:To prevent the cut-off end of a sheet band from becoming defective, to keep the overlaid band from being deformed, by making the circumferential speed of a roller higher than the moving speed of the sheet band at the same time as the cut-off of the band in its winding on the roller, to remove the cut- off end of the band of a looseness, a wrinkle and a fold. CONSTITUTION:When the piston rod of an air cylinder 38 on a winding arm 5 is protruded, a cutter 20 cuts off a sheet band 4 between a guide bar 17 and a roller 2. At that time, a limit switch is turned on to put a timer into operation to make the circumferential speed of the roller 2 higher than the moving speed of the sheet band 4. For this reason, a slip is caused between the peripheral surface of the roller 2 and the band 4 being wound thereon, at the same time as its cut- off, so that the band is removed of a looseness, a wrinkle and a fold from the cut-off end and then wound. The cut-off end of the band is thus prevented from becoming defective, so that the sheet band overlaid on the cut-off end is kept from being deformed.

Patent JP-H042927-A (JP)
Title: Mechanical vibration sensor
Inventor: SAKATA MINORU
IPC: G01H11/06
Filed: 1990-04-19
Abstract: PURPOSE:To obtain good detecting sensitivity over a wide frequency range by providing a vibrator chamber having a vibrator built therein and which is filled with an electrid viscous fluid, an electrode for impressing a voltage to the electroviscous fluid, and means for impressing a voltage corresponding to the frequency of an electric signal to the electrode. CONSTITUTION:A cantilever vibrator 7 and an opposing electrode 9 fixed opposite to the vibrator 7 are provided in a vibrator chamber 3 in a sealed structure. The change of the electrostatic capacitance between the vibrator 7 and electrode 9 is converted to the change of a voltage by an electrostatic capacitance/voltage converter 11, and the change of the voltage is converted to an electric signal of the frequency corresponding to the vibrating number by a voltage/frequency converter 13. The electric signal is output to an output terminal 15. When the vibrator 7 detects vibration, the voltage corresponding to the frequency of the vibration is, through the frequency/ voltage converter 21, impressed between control electrodes 19 and 21. Therefore, as the detected frequency of the vibration is higher, a larger voltage is impressed between the electrodes 19 and 21, and the viscosity of an electroviscous fluid 17 is correspondingly increased. As a result, the damping effect for the high frequency vibration is enhanced and the sensitivity of the low frequency vibration to the high frequency vibration is improved.

Title: Predicting method for lead storage battery life
Inventor: NISHIMURA KYUZO
IPC: H01M10/48
Filed: 1989-04-24
Abstract: PURPOSE:To predict the life of a battery through a simple method and with high precision by detecting the voltage of the battery under being charged with electricity for integrating the quantity of charged electricity on and after the approximate attainment of a battery voltage to a constant voltage, and then predicting the battery life from the integrated value. CONSTITUTION:A charged current I is detected by a charging current detector 4. A charged battery voltage V is meanwhile detected by also a battery voltage detector 5, and the subsequent rise of the voltage V to a rated constant voltage VI causes the voltage detection output signal to be transmitted to a timer 10 which is operated by the detection output signal so as to output a timer signal after the passage of a predetermined time. Entry of this timer signal causes a relay 11 to be operated so as to make a contact 11a, and therefore a charged- electricity quantity integration unit 12 integrates the quantity of charged electricity according to the charged current detected by the charging current detector 4 for transmitting the integrated value to a life calculating unit 13. The life calculating unit 13 calculates the ratio of the integrated value to the quantity of overcharged electricity regarding the actual service life of a specified type storage battery 3, the information of which is pre-entered into the unit 13, so that the calculated value is displayed as a predicted life value by a life display unit 14. The battery life can thus be predicted through a simple method and with high precision.

Title: Manufacture of polyamide film
Inventor: HAMANO AKITO
IPC: B29C48/08
Filed: 1984-05-22
Abstract: PURPOSE:To manufacture a polyamide film having excellent uniformity of thickness with good efficiency by a method in which a specific polyamide resin is melted and molded into a film by extrusion, closely adhered to a rotary cooling roll electrostatically, and hardened by cooling. CONSTITUTION:A polyamide resin containing a metal compound and having a melt specific resistivity (at 260 deg.C) of 1.5X10<5>OMEGA.cm or less and a melt viscosity (at 270 deg.C) of 250-1,800 poise is melted and extruded into a film. The film is closely adhered to a rotary cooling roll electrostatically and hardened by quick cooling. The small melt viscosity of the polyamide resin favors the enhancement of the electrostatic adherence of the film, but when the melt viscosity is too small, the melt moldability of the resin and the mechanical strength of the film are lowered. In the case of polyamide containing no metal compound, small melt viscosity serves to increase the electrostatic adherence property, and even in polyamide resin containing metal compound and having small melt specific resistivity, the small specific resistivity, the higher electrostatic adherence.
