Title: Current supply circuit
Inventor: ODA SHINJI
IPC: H03F3/343
Filed: 1987-12-09
Abstract: PURPOSE:To obtain a stable output by providing a current mirror circuit having at least >=2 current outputs so as to form an operational amplifier and a negative feedback loop thereby controlling the output current depending on the resistance of an externally mounted resistor even when the current amplification factor of a transistor(TR) is dispersed. CONSTITUTION:A voltage V is inputted to a noninverting input of an operational amplifier A1 and a current in response to the output flows to a TR Q2. In a current mirror circuit comprising TRs Q2, Q3, Q4, the collector current of the TR Q3 flows to an externally mounted resistor R2. Since a voltage across the resistor R2 is given to an inverting input of the operational amplifier A1, TRs Q1, Q2, Q3 and the operational amplifier A1 form a negative feedback loop. Since the noninverting input and the inverting input of the operational amplifier are of the same potential, the voltage caused in the R2 is equal to the input voltage and a current I0=V/R2 flows to the resistor R2. Since the current flowing to the inverting input of the operational amplifier A1 is negligible, the collector of the TR Q3, and the collector of the TR Q4, that is, the output terminal 12 has a current I0=V/R2 and a current required in the inside of the IC is controlled accurately by the externally mounted resistor.

Title: Automatic vending machine
Inventor: TOMIOKA TOSHIICHI
IPC: G07F9/10
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent an automatic vending machine from being contaminated by the inside invasion of insects or the like by providing a forced geneting means for a harmful insect repellent inside the casing of automatic vending machine. SOLUTION: Inside an automatic vending machine 1, a repellent generator 8 is provided as the forced generating means for the harmful insect repellent. Concerning the repellent generator 8, a solid agent adsorbing an insect agent to a carrier such as silica gel is heated by a heater as the harmful insect repellent and the component of repellent is evaporated. Concerning heating in the case of low steam pressure pyrethroid chemical, smooth heating is enough and even when a dedicated heater is used, a little power consumption is enough. Otherwise, even without especially using any heater, heat at a heating section such as a fluorescent lamp 16 or the radiator of cooler 18 can be utilized as well.  Thus, when the repellent is generated by the repellent generator 8, the inside is filled with the repellent and it is leaked outside the casing so that insects do not get closer to intervals or the like.

Title: Semiconductor storage device
Inventor: WATANABE YOJI
IPC: G11C11/34
Filed: 1986-12-26
Abstract: PURPOSE:To obtain a dRAM with a large sense margin and to extend its refresh cycle by arranging dummy cells along dummy bit lines parallel to bit lines and selecting one dummy cell with one word line. CONSTITUTION:The dynamic type dRAM is provided with one dummy cell for each word line WL and also provided with a couple of dummy bit lines DBL for transferring information charges to and from those dummy cells DC; when a memory cell MC selected with some word line WL is connected to one bit line of a bit line couple PL, one dummy cell DC driven with this word line WL is connected to the other bit line BL from a dummy bit line DBL through a switch circuit. Only one dummy cell is therefore selected with one word line, so a reference potential written therein is left as it is for nearly the same time with the information potential of memory cells. Consequently, the potential of the dummy cell is fixed and the high sense margin is held for a long time.
