Title: A-d converting circuit
Inventor: MARUMO YOSHIHARU
IPC: H03M1/52
Filed: 1981-03-10
Abstract: PURPOSE:To measure the mean value of an input signal with an optional period accurately by automatically varying the reference voltage of a double integral type A/D converting circuit according to the period of an input signal. CONSTITUTION:A current (i) from an artificial pendulum oscillating circuit A is converted by an operational amplifier OP1 into a voltage (a), FFs F1 and F2 are set by a signal (b) obtained by shaping the waveform of the voltage (a), and analog switches S1 and S3 are closed by the output of the F2. The voltage (a) is integrated for one period by the 1st integrator composed of an operational amplifier OP2, a resistance R1, and a capacitor C1. A reference voltage from a Zener diode D is passed through the S3 and then integrated for one period by the 2nd integrator composed of an operational amplifier OP3, a resistance R2, and a capacitor C2. After the one period, the F1 amd F2 are reset by the Q' output of an FFF3 and the S1 and S3 are opened to turn on the switch S2 of a control circuit, thereby performing reverse integration by the 1st integrator with the output signal (h) of the 2nd integrator. When the output of the OP2 is ceased,  a pulse generator W is triggered to reset the F3 by its output, and then a gate  G2 is opened to count a clock P by a counter CT, calculating the mean value of the current (i).

Title: Spot knocking unit of cathode-ray tube
Inventor: TAKAHASHI SUSUMU
IPC: H01J9/44
Filed: 1978-03-24
Abstract: PURPOSE: To perform spot knocking without damaging a cathode-ray tube by providing a prescribed-value capacitor in the electrostatic capacity which donnects the cathode terminal of a socket to one of electrode terminals except the anode terminal.  
     CONSTITUTION: When discharge in a tube is caused between anode 13 and the first grid 20, the discharge current is flowed to voltage supply terminal 304 of ground potential from the first grid terminal 11 through  capacitor 25, so that the voltage between grid 20 and cathode 19 may be prevented from rising, and the secondary discharge in the tube is not caused between them. Similarly, even when discharge in the tube is caused between anode 23 and heater 18, the secondary discharge in the tube is not caused between cathode 19 and heater 18. Since heater 18 is a resistor and the discharge current can hardly flow to heater 18, it is necessary to insert capacitors 26 and 27 between heater terminals 8 and 9 and respective cathode thermnals 10. Capacitors having electrostatic capacity range 0.001 to 10μ F can be used as these capacitors.

IPC: H01L23/495
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor chip capable of preventing a deformation due to a mechanical pressure and a stress and a semiconductor device of chip- on-chip structure. SOLUTION: A slave chip 2 is supported above a master chip 1 by connecting a slave side bump B2 to a corresponding master side bump B1. The bumps B1 and the bumps B2 contain a functional bump B1 and the bump B2. The chip 1 is electrically connected to the chip 2 by connecting the bumps BF to each other, and the connection of the bumps BD does not contribute to electric connection of the chip 1 and the chip 2. That is, since a dummy bump which does not contribute to the electric connection to a solid is formed on an opposed surface of another semiconductor chip to a solid surface (substantially flat surface) of a circuit board or the like, in addition to the functional bump for the electric connection to the slid, a force operating the chip can be dispersed in the case of connecting the chip to the solid to seal it with resin or the like.

Title: Automatic vending machine
Inventor: YOKOI KANJI
IPC: G07F9/00
Filed: 1990-02-15
Abstract: PURPOSE:To make it possible to sufficiently heat/cool a commodity and vending the heated/cooled commodity even if residual number of unfed commodities is small by aborting commodity vending when the residual number of commodities arrives at '0' before a timer counts up a prescribed time, and when the timer counts up the prescribed time, allowing the commodity vending. CONSTITUTION:When the vending of commodities is frequent in the summer or winter season, it may frequently occur that the residual number of commodities becomes zero because of a sellout or the residual number is small. In this case, the residual number is stored in a residual number memory 14 by the vending of a commodity after feeding commodities before the timer 12 counts up the prescribed time. When the residual number becomes zero, a vending aborting means is driven to abort commodity vending. When the timer 12 counts up the prescribed time after sufficiently cooling or heating the fed commodities, a vending allowing means is driven and commodity vending is allowed. Thereby, even when the residual number of commodities is small, the commodities can be vended after sufficiently cooling or heating them.
