Abstract: PROBLEM TO BE SOLVED: To provide a commodity discharging device for an automatic vending machine the thickness of which device is reduced without hindering its commodity discharging operation. SOLUTION: Two discharge units 30 which are facing the storage carrier paths 5 can be placed back to back between a pair of paths 5. A protruding upper stopper 33 regulates the falling of the second lowest commodity 4 included in the path 5, and at the same time a lower stopper 35 moves back to its storing posture to cancel the regulation caused by the stopper 35 and accordingly discharges the lowest commodity 4 under the path 5. In such a constitution of the commodity discharging device used for an automatic vending machine, the inner side of a part of the stopper 33 where the commodity 4 is received and restricted is formed almost in a sawtooth shape. Then the sawtooth shape parts 33a of the units 30 set back to back are alternately placed with no mutual interface caused between them.

Title: Amplifier
Inventor: NAKATSUKA TADAYOSHI
IPC: H03G3/10
Filed: 1987-07-27
Abstract: PURPOSE:To realize the input output matching and the low distortion at the time of attenuating a gain by inserting a high frequency attenuator composed of a field effect transistor FET into the front step of a wide band amplifier. CONSTITUTION:A wide band amplifier connects a high frequency attenuator connected serially and in parallel to a pi shape with plural FETs 102-104 to the front step. When an input signal power is minimum, the potential of an attenuating quantity control terminal 116 is made into 0V, the drain source resistance of the FET 102 is lowered, the attenuating quantity is made into the minimum condition, and reversely, when the input signal power is maximum, the potential of an attenuating quantity control terminal 117 is lowered, an FET is made into a pinch-off condition and the drain source resistance is made maximum, namely, the attenuation quantity is made maximum. Usually, the condition between these is obtained, and the attenuation is executed in accordance with the input signal power. The input output impedance matching is executed by controlling the potential of an impedance control terminal 115 and changing the drain source resistance of the FETs 103 and 104. Thus, the input output matching is kept and the attenuation can be executed without generating a high order distortion.

IPC: H04J13/00
Filed: 1987-07-27
Abstract: PURPOSE:To improve a signal-to-noise ratio without changing a process gain by close arranging plural primary modulated wave signals in a condition in which they are not interfered and executing a spectral spreading by a single spreading code. CONSTITUTION:Plural primary modulated wave signals are prepared to a piece of information data, respective primary modulated wave signals are close arranged in maintaining the condition in which they do not interfere with one another, and by executing a spreading by a spreading code to consider a clock signal frequency for the spreading code set beforehand and the period of the spreading code, the spectral spreading without a spectral interference is executed. Further, at the time of demodulating, the detection of plural modulated wave signals, after a reverse spreading, is executed. Thus, the S/N of the information data obtained by being detected can be improved in proportion to plural primary modulated wave signals, and when an S/N improvement degree is equal, a spectrally spread band width can be made narrow by the degree.

IPC: B29C48/08
Filed: 1985-08-28
Abstract: PURPOSE:To prevent the generation of die line, gear mark, transfer mark, adhesion mark and warping by a method wherein molten resin, extruded out of a dice, is pinched and pressed by one pair of cooling rolls, which are contacted by the resin at a first time, while the surface temperature of a roll, only pinching and pressing the molten resin but never carrying and sending the resin, and the same of the other roll are maintained in specified ranges. CONSTITUTION:Molten resin, extruded out of a die 1, is pinched and pressed by one pair of cooling rolls, to which the molten resin contacts at a first time, and the roll A among the cooling rolls, which only pinches and presses the molten resin but never support and carrying it, is maintained at 30-90 deg.C in the surface temperature thereof.

The surface temperature of the other roll B is maintained at 100-140 deg.C. Warp, shrinkage strain, wavy streaking or the like is readily generated when the surface temperature thereof is up to 100 deg.C while adhesion mark may be generated readily when it exceeds 140 deg.C.

Title: Mosfet and manufacture of the same
Inventor: SAKURAI JUNJI
IPC: H01L27/12
Filed: 1986-08-12
Abstract: PURPOSE:To reduce hot electron deterioration and improve radiation-resistant characteristics by a method wherein the end of the gate insulating film of an MOSFET is provided inside the gate electrode or the gate electrode is composed of gas. CONSTITUTION:A gate insulating film 3 has its end at an arbitrary position below a gate electrode 4 or the gate insulating film 3 has its end inside a drain so as to avoid electric field concentration near the drain. As the specific inductive capacity of the air or a vacuum is 1/4 of that of SiO2, if the end exists in the channel region near the drain, the electric field concentration at that part can be relieved so that hot electrons can not easily be produced. Moreover, the space where the carriers are trapped is reduced with the composition area of the gas in the gate insulating film and the radiation-resistant characteristics can be improved.
