IPC: H02M3/28
Filed: 1979-05-28
Abstract: PURPOSE:To omit a transverse current correcting circuit and thus to simplify a circuit configulation of a parallel operation inverter by driving a conversion unit of a subsidiary inverter according to driving signal of a main inverter. CONSTITUTION:An inverter is constituted with one main inverter 10 in parallel operation and one more subsidiary inverters 11. The main inverter is constituted with an oscillator 4 to determine AC frequency, a conversion unit 5 to obtain an alternating current by means of a semiconductor switch, a filter unit 6 to extract a sine wave from an output of the conversion unit 5, and a driving circuit 7 to set an AC output frequency and drive the conversion unit 5 so as to make an output voltage constant. The subsidiary inverter 11 has the conversion unit 5 and the filter unit 6 and is driven by a driving signal from the driving circuit 7 of the main inverter 10. Since both main and subsidiary inverters are operated by the same driving signal, the inverter can be balanced in good condition, and a complicated transverse current correcting circuit can be omitted to simplify a circuit configuration.

Abstract: PURPOSE: To make it possible to take out efficiently without causing any damage to a container, by lifting a conical article, such as a container of ice cream in process, from a conveying belt in a refrigerator by a supporting piece of a circulating chain taking advantage of shape of the container and carrying it outside of the system.  
     CONSTITUTION: A conical container 9 is automatically put into a receiving unit 81 of a circulating conveyor belt 1 by a feeding device, and while it goes round inside of a refrigerator, ice cream in process held in the container 9 solidifies and becomes a finished product. When the container 9 is passing under a take-out device 4, top of the container 9 becomes loosely fit in between a set supporting pieces 7 and 7a hanging downwardly from the circulating chain 5 on the both sides. The conveyor belt 1 and the circulating chain 5 travel at a constant speed while maintaining this condition, and when space between a pair of the chains 5 became narrow, the pair of supporting pieces 7 and 7a contact outside circumference on the top of the container 9. When the chain 5 is going up along an inclined section 62 of a guide lever 6, the pair of supporting pieces 7 and 7a lift and carry the container 9. As space between the circulating chains becomes wider at the downstream side of the inclined section 62, the container 9 falls onto a chute 10.

IPC: G11B5/733
Filed: 1985-03-28
Abstract: PURPOSE:To obtain practicable durability which does not depend on a magnetic head material by forming a magnetic recording layer consisting of a thin ferromagnetic metallic film on a substrate having preliminarily provided fine particle projections and the fine particle projections of oligomer which deposit in the stage of forming the film. CONSTITUTION:The fine particle projections 10 are preliminarily fixed by a resin 11 of a base film 8 consisting of a high-polymer material and the fine particle projections 9 of the oligomer are deposited in the stage of forming the film. The magnetic recording layer 12 consisting of the thin ferromagnetic metallic film is formed on the film 8. Since the micro-projections having different hardnesses are disposed on the surface, the adhesion arises hardly even if the magnetic head is of an alloy or oxide type. Even if the adhesion arises, the adhered layer is removed by polishing and therefore the cause for the generation of a flaw can be eliminated from the permanent adhesion if the hardness is higher. The surface of the magnetic recording layer having the durability to permit the use in a still state under various kinds of environment even when adopted for an important alloy head is obtd. by increasing the density of magnetic recording.

Abstract: PURPOSE:To attain easily troubleshooting of a failed interphone set by detecting a signal transmitted to a transmission line for a call signal so as to drive a display device and discriminating whether or not the set is failed depending on the operating state of the display device. CONSTITUTION:When a call signal is transmitted from an interphone set E to an information line B, interphone sets F, G inputs the call signal to a control section 4 and the control section 4 discriminates whether or not the call signal is coincident with a preset own station number. When they are coincident, a talking section 3 is driven to ring the call tone and also to connect a talking line C and the talking section 3 thereby attaining talking. On the other hand, if a failure takes place in the circuit of the set E and a signal is outputted continuously to a call signal output port of the control section 4 or transistors 6, 9 are operated in error to be turned on continuously, a signal similar to the call signal is outputted continuously on the information line B, thereby inactivating the entire system. In this case, a display function LED15 is lighted continuously on the failed set E and the failed interphone set is distinguished easily.
