Title: Detecting and displaying circuit of power supply voltage
Inventor: OOSAKI YOSHIHARU
IPC: H02J7/00
Filed: 1983-05-11
Abstract: PURPOSE:To display the state of the voltage of one power supply by the other power supply when its voltage is reduced by providing a power supply for detecting the variation of a power supply voltage and a power supply for driving a display part independently. CONSTITUTION:It is supposed that the power supplies A4, A5 are formed and the power supply A4 has larger current consumption and its power supply voltage is precedently reduced. The variation of the power supply voltage of the power supply A4 is applied to the base of a transistor (TR)13 through a constant voltage diode 11 and amplified. A diode (D)12 is set up so that the load of the TR13 is suddenly increased at a part close to the lower limit value of the power supply voltage of the power supply A4 and a constant voltage diode 14 fixes the emitter voltage of the TR13. A CMOS inverter 15 operates surely at the lower limit vaue of the power supply voltage, and when the output of the inverter 15 is inverted, a TR17 is turned on, an LED16 lights up and the voltage reduction of the power supply A4 is displayed. The LED16 is turned on by the power supply B5 and the consumed status of both power supplies A4, B5 can be uniformed.

Title: Mold for injection molding
Inventor: FUKUSHIMA AKIRA
IPC: B29L11/00
Filed: 1991-03-22
Abstract: PURPOSE:To miniaturize mold clamping members and to obtain molds for injection molding wherein the mold clamping members and the molds are prevented from deterioration. CONSTITUTION:Molds 2 and 3 (with a thermal expansion coefficient of alpha2) are joined together at a low temp. condition and bolts 1 (with a thermal expansion coefficient of alpha1:alpha1<alpha2) are screwed therein to clamp the molds. Then, the molds 2 and 3 with the bolts 1 are heated up to a specified temp. Because of difference between the thermal expansion coefficients, strains in the molds 2 and 3 become larger than strains in the bolts 1 and as the result, the molds 2 and 3 are clamped stronger than at the timer of clamping and the condition is kept by themselves. In a gradually cooling process after filling a resin, accompanied with lowering the temp., the difference in amt. of strain between the bolts 1 and the molds 2 and 3 becomes less and a self-holding force of mold clamping is decreased accordingly.

Filed: 1982-05-18
Abstract: PURPOSE:To perform data waveform shaping with an optimum slice level, by detecting the upper and lower limit values of the slice level, and generating the voltage equivalent to the mean value between said upper and lower limit values to use as a slice level. CONSTITUTION:An error flag 9 showing the correctness of data is delivered from an error detecting circuit 6 and compared with the DC value through the 2nd level comparator 11. A slice level 4 which is supplied to the 1st comparator 1 is supplied from the 2nd D/A converter 12. The input data of the converter 12 is varied by a clock pulse B and a counter 14. The input voltage of the comparator 11 varies in response to the change of the level 4. When this input voltage is equal to a certain voltage level, a latch 15 transfers upper and lower limit values V1 and V2 to an alithmetic unit 16. Then the latch 15 calculates the mean value between the values V1 and V2 which is equivalent to the optimum value of the level 4 and transmits it to the converter 12. In such a way, it is possible to perform data waveform shaping with an optimum slice level.

Title: Rewinding control device for paper manufacturing machine
Inventor: UMEMOTO FUJIO
IPC: B65H23/198
Filed: 1989-04-03
Abstract: PURPOSE:To maintain the optimum speed response from a start of paper rewinding to its end by providing a speed response gain correcting means which continuously changers a speed response gain in a speed control system so as to compensate a change amount of GD<2> of a spool containing paper in accordance with a change of detected rewinding size. CONSTITUTION:When a rewinding diameter D is input, a function generator 18 outputs a speed response gain correction coefficient K such as compensating GD<2> of a spool containing paper in accordance with this rewinding diameter D, accordingly when the diameter is gradually increased, this correction coefficient K is continuously changed. Next, a multiplier 19 multiplies a speed response gain, determined by ratio of a resistor R1 to a series circuit of a resistor R2 and a capacitor C, by the correction coefficient K and the result of multiplication is output. Accordingly, the speed response gain G of a speed control part 13 is continuously changed so as to compensate a change amount of GD<2> of the spool containing paper. As a result, the optimum rewinding condition can be maintained from single unit state of a reel drum until the state of its maximum rewinding size in relation to the spool.
