Title: Automatic vending machine
Inventor: HAGIMOTO TAKEO
IPC: H05B6/10
Filed: 1988-03-04
Abstract: PURPOSE:To remove troubles such as the different in heating degree due to the capacity of a drink can and to improve an operation rate by detecting a voltage generated in a power switch semiconductor, deciding the capacity of the drink can, determining a heating output, and controlling the heating output. CONSTITUTION:A heating coil 1 is cylindrically wound along a can wall including all drink cans 15-19 having different capacities. A voltage resonance type inverter changes its operation waveform at the time of changing a distance between the heating coil 1 and an object to be heated in accordance with the characteristics. Namely, VCE(P), IC/d(P) to be the peak values of voltage IC/P to be the sum of collector-emitter voltage VCE and current flowing into a diode 4' reversed from a collector current is increased in accordance with the increment of the distance and reduced in accordance with the decrement of the distance. Since the equivalent distance between the heating coil 1 and a drink can 2 is changed in accordance with the difference of the shape of the drink can 2 in the heating coil 1, the value of the VCE(P) generated in accordance with the difference is changed.

Title: Blocking-resistant heat sealer foam and its manufacture
Inventor: SAITOU HIROSHI
IPC: G03G7/00
Filed: 1980-04-22
Abstract: PURPOSE: To eliminate the softening trouble of a sealer at time of fixing a print by means of an electronic printer by applying a blocking resistant agent on a heat sealer applied on a foam base, thus preventing blocking prior to printing.  
     CONSTITUTION: A heat sealer consisting of a hot melt adhesive of e.g. a copolymer of a polyacetic vinyl resin and a polychloric vinyl resin is coated on a sealing part of a foam base, and the a blocking inhibiting agent consisting of a partially saponified polyacetic vinyl, etc. is applied on the heat-sealer applied surface. A blocking inhibiting heat sealer foam thus obtained is printed by an ordinary method. After this process, the blocking resistant agent is removed at temperature not more than a heat seal agent melting point (or softening point) to perform a heat sealing. The blocking inhibiting heat sealer foam is free from the generation of blocking during storage and transportation prior to printing. In addition, it is possible to prevent the generation of blocking when a print is heated and fixed by means of an electronic printer and also alleviate the temperature control of heating and fixing.

Title: Sound circuit in pinball machine
Inventor: RI SEIMOU
IPC: A63F7/02
Filed: 1989-03-03
Abstract: PURPOSE:To dispense with power loss and adjust the volume of a speaker by connecting a series circuit having a capacitor and a switch for controlling the current supply and interruption to the capacitor in parallel to the speaker. CONSTITUTION:The spectrum of sound outputted from a speaker 5 includes a plurarity of high frequency components rather than a single frequency. When the speaker is operated in the small volume mode, a switch S1 is turned on to make a capacitor C1 effective. Then, the high frequency component bypasses the capacitor C1 and is not applied to a coil L of the speaker 5. Thus, the interval pronounced is lowered while the volume is reduced. By removing the high frequency component with a high frequency shutting-off circuit and consequently reducing drive power applied to the coil L of the speaker 5, the volume is reduced, so that the conventional power loss due to resistance is not produced.

Title: Electric discharge machining method
Inventor: INOUE KIYOSHI
IPC: B23Q11/10
Filed: 1980-04-21
Abstract: PURPOSE:To carry out stable machining at high processing velocity by controlling a processing liquid supply volume for electric discharge machining at a specific value against the processing volume of works and also controlling a supply pressure at a specific pressure level. CONSTITUTION:If a processing liquid supply volume for electric discharge processing is set at a rate of 400-3,000cc per one gram of processing volume, processing velocity becomes the maximum. In addition, a supply pressure for resisting against an electric discharge pressure is set at 10-100kg/cm<2>. Since the processing volume is determined by an energy applied to a processing clearance, a detection signal for processing power from a detection circuit 11 is inputted to a control circuit 10, controlling valves 8, 9, so that a processing liquid flow becomes the optimal value according to a processing volume. If controlled in this way, it is possible to remarkably improve processing velocity even under the same machining conditions.

Title: Receiving device
IPC: H04B10/548
Filed: 1992-03-11
Abstract: PURPOSE:To increase the band of the receiving frequency by applying both upper and lower heterodyne detection systems and switching these systems to each other according to the received signal frequency. CONSTITUTION:An image cancel mixer 25 receives the upper or lower band of the local oscillation signal inputted to the mixer 25 from a local oscillation circuit 17 and cancels the other band as an image signal. The one of both bands that should be canceled is decided by the control signal received from a switch signal generating circuit 203 which receives the channel selection data given through a terminal 29 and produces a switch signal. At the same time, a base band signal is outputted from a terminal 14 via a polarity switching circuit 20 so that the different polarities of the upper and lower bands are matched with each other. The switching of the mixer 25 links to the switching of the demodulation output of the circuit 20. Thus both upper and lower bands of the oscillation signal can be received in a wide frequency band.

Abstract: PURPOSE:To obtain the titled firmly bonded safety glass having high safety, by applying butyl rubber to a circumference of the edge of a glass plate leaving an opening part, pressing another glass plate to the butyl rubber, filling a specific resin into the gap through the opening part and sealing the opening part with butyl rubber. CONSTITUTION:Butyl rubber 3 is attached to the circumference of the edge of a glass plate 1 leaving an opening part 2. Another glass plate 4 is pressed to the butyl rubber 3 to integrate the glass plates 1 and 4. Methyl methacrylate 5 is poured into the gap 6 through the opening part 2 and the part is sealed with butyl rubber 3 to obtain a sound-insulating safety glass. Since all the materials existing between the glass plate pair are liquid resins, the generation of void can be completely prevented even if the glass plates have irregular bonding surfaces and, accordingly, the plates are firmly bonded together and the generation of bubbles, dew condensation and clouding of the glass can be prevented. The safety glass is resistance to break because of its flexibility and has excellent safety, sound-proofing and sound-insulating properties. It can be easily bored to form a beautifully machined product. Methyl methacrylate is available at a low cost.
